In order for its continued use, it must be validated. Many studies conducted on motion palpation’s inter-examiner reliability in the spine have shown it to be below average, however only a few studies have addressed its use in the extremity joints. No inter-examiner reliability studies on motion palpation were found for the elbow, let alone the symptomatic elbow with regards to chronic lateral epicondylalgia, a common disorder of the elbow effectively treated by the use of manipulation. Objectives The objectives of this study were to determine the inter-examiner reliability of motion palpation of the elbow for the asymptomatic elbow and the symptomatic elbow with regards to chronic lateral epicondylalgia. It also aimed to compare these results to determine any difference in reliability, the number of manipulable subluxations and the presence of manipulable subluxations in particular directions, between the two groups. Method Twenty participants (n=40 elbows) between the ages of 18 to 65, with one asymptomatic and one symptomatic elbow (chronic lateral epicondylalgia) were examined by three final year masters chiropractic students for the presence of manipulable subluxations in end play, using only motion palpation. The examiners were pre-trained, randomised and blinded. Each examiner individually motion palpated both elbows on each participant, in nine directions of motion palpation, incorporating the humeroulnar and proximal radioulnar joints. They were also required to identify which elbow was symptomatic. Fleiss’ kappa and percentage agreement (perfect percentage agreement and mean percentage agreement) were used to measure reliability. Paired non parametric Wilcoxon signed ranks compared the difference between both groups and McNemar’s chi square tests assessed the percentage of correctly identified symptomatic elbows for each examiner. A p value <0.05 was considered statistically significant. iv Results The asymptomatic elbows showed a poor range of kappa results, from 0.0683 to -0.1321, with a mean kappa of -0.0664. Perfect percentage agreement was 50% to 85% and mean percentage agreement was 83.30% to 94.99%. The symptomatic elbows’ kappa values ranged between -0.2691 to 0.4034 with a mean kappa of -0.0028. The humeroulnar medial to lateral direction of motion palpation had a moderate kappa value of 0.4034. Perfect percentage agreement ranged from 10% to 85% and mean percentage agreement from 69.94% to 94.99%. There was an insignificant difference in kappa values between the two groups (p=0.260), although there was a trend towards the asymptomatic kappa values being lower than the symptomatic values. The difference between symptomatic and asymptomatic elbows was significant in proximal radioulnar posterior to anterior glide in pronation (p=0.013), as well as proximal radioulnar rotation of the radial head on the ulna (p=0.008). Overall, more manipulable subluxations were found in the symptomatic elbows than in the asymptomatic elbows. The examiners correctly identified the symptomatic elbow in 65% to 90% of participants (p=1.000). Conclusions and Recommendations In conclusion, the inter-examiner reliability of motion palpation in the asymptomatic elbow was poor, and in the symptomatic elbow (chronic lateral epicondylalgia), poor to moderate. There was an insignificant difference in reliability between the two groups, although more manipulable subluxations were found in the symptomatic elbows overall. These were mainly in proximal radioulnar posterior to anterior glide in pronation, as well as proximal radioulnar rotation of the radial head on the ulna, two directions of motion that form part of Mills’ manipulation. This study also found that examiners were able to identify the symptomatic elbows with the use of motion palpation. It is recommended that future research continue from this study in assessing the identification and presence of manipulable subluxations in all the extremity joints. However the methodological problems with the statistical analysis need to be addressed.

Dissertation submitted in compliance with the requirements for the Master's Degree in Technology: Chiropractic, Durban University of Technology, 2013. / Background: Horses are unlike most animals as they take part in equine sports and thus are athletic animals. Comparable to a human athlete, horses are prone to sports related injuries and disease. Equine chiropractic has shown to be one of the most utilized forms of complementary and alternative veterinary medicine (CAVM) worldwide, providing a drug free approach to equine health care and maintenance. However, equine chiropractic lacks research and therefore a wide gap in the literature exists. Studies on CAVM therapies have shown that these therapies are largely driven by the public and the public’s perceptions towards these therapies. However, little is known of the public’s perceptions towards equine chiropractic in KwaZulu-Natal (KZN). Horse riders represent the primary contact with the horse and are in the best position to note the outcome of post equine chiropractic treatment. For this reason they have influence on the utilization of equine chiropractic. It is, therefore, important to attempt to close the gap through ascertaining the horse riders’ knowledge, perception and utilization of equine chiropractic, particularly in KZN, where no such data exists. Aim: The aim of this study is to determine the knowledge, perception and utilization of equine chiropractic amongst horse riders in the KZN region. Method: The research design is a descriptive, quantitative, self administered survey based study. The study population included all horse riders in KZN (N= 500). There is no available list that details the number of horse riders in KZN, therefore, it was estimated that there are 500 horse riders in KZN (This was based on the number of horses stabled in KZN). The study sample included all horse riders at stable yards in KZN that had given written permission for the research to take part at their yard (N= 330). This was estimated by the number of horses stabling at the yards where owners had given written permission. Results: The response rate was 25% (n=83). The respondents were predominantly white (98%) and female (81%), and between the ages of 41- 50 years. Most respondents had previously been treated successfully by a chiropractor and had tertiary education. The majority of respondents were part of a horse society and participated predominantly in show- jumping. Most respondents had ridden horses for 0-10years, and currently rode only one horse. Their main horse (the horse they rode the most), for which most respondents were both the owner and rider, stayed predominantly in a stable and was between the ages of 5- 10 years. Most respondents had not sought alternative veterinary care for this horse, but had sought alternative veterinary care for their other horse(s) that they rode. Out of all the alternative veterinary therapies respondents reported to utilize, equine chiropractic showed to have the highest utilization. Equine chiropractic reported to have an overall high success rate with both the respondents’ main horse (92%) and their other horse(s) (87.5%). Respondents’ overall subjective knowledge of equine chiropractic was ‘that they knew something about it’. Respondents’ objective knowledge score was 75%. Most respondents had gained their knowledge of equine chiropractic through a friend and stated that the information they had gained was favourable towards equine chiropractic. It was interesting to note that 90% of respondents had some knowledge of equine chiropractic. Most respondents knew of one or more equine chiropractor(s), and were referred to them predominantly by a riding instructor. Just under half (49.4%) of the respondents had utilized an equine chiropractor, yet most respondents showed to have accurate knowledge of what equine conditions chiropractors treat. The majority of respondents supported the future utilization of equine chiropractic, but would like more information on equine chiropractic techniques. The research data revealed a trend showing that the utilization of alternative equine therapies or equine chiropractic corresponded with an increased knowledge of equine chiropractic. The data revealed graphically that the more equine chiropractors a respondent knew of, the more they utilized equine chiropractic. Conclusion: Respondents showed predominantly to have a positive perception towards equine chiropractic. Their knowledge of equine chiropractic was overall accurate and they showed to utilize and support the future utilization of equine chiropractic.

Completed in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic, Durban University of Technology, 2014. / Background: Dry needling is known to be effective and efficient in the treatment of myofascial pain syndrome; pragmatically however, patients utilise Flurbiprofen LAT patches as home therapy anticipating similar results. This may not be true and thus, this study aimed to investigate the effectiveness of dry needling versus Flurbiprofen LAT patches in the treatment of myofascial pain syndrome of the upper Trapezius muscle. Methods: This ethics approved, prospective, randomized, single blinded (blinded assessor), comparative clinical trial required sixty participants, randomly (randomisation table) allocated to two groups. After the completion of informed consent participants received treatment over three consultations with a follow up a week later. Baseline and repeated outcome measures included Numerical Pain Rating Scale, Neck Disability Index Questionnaire, Myofascial Diagnostic Scale, Algometer and Cervical Range of Motion device. The data was analysed using ANOVA tests with the p-value set at 0.05. Results: Baseline demographics and outcome measures showed that only age was significantly different between the groups. This difference was controlled for in the statistical analysis. Dry needling resulted in better treatment outcomes than the Flurbiprofen LAT patches in terms of function (cervical range of motion) (right lateral flexion p=0.043) and Myofascial Diagnostic Scale scores (p<0.001), whereas the Algometer measures and remaining cervical ranges of motion improved significantly over time in both groups, but not between the groups. Tthe Flurbiprofen LAT patches fared better in terms of the subjective reporting (Numerical Pain Rating Scale), this was not significant. Conclusion: The interventions were both effective over time, however, the needle group achieved improved functional ability and the Flurbiprofen LAT patches improved the pain outcomes with limited functional ability. Therefore the use of these modalities requires clinical judgement to appropriately administer the treatment option that the patient would best benefit from.

Submitted to the Faculty of Health at the Durban University of Technology in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Department of Chiropractic, Durban University of Technology, Durban, South Africa, 2015. / Background: Cryotherapy is often the first option in treating acute conditions and can be applied in various forms including ice packs and cooling gels. Cooling gels are easy to use and readily available making them popular with consumers. They can also contain additional ingredients which can assist with inflammation, making them ideal for musculoskeletal disorders. A cooling gel containing menthol and anti-inflammatory herbs is available in pharmacies nationwide in South Africa, but has not been clinically investigated. This gel is often used in the treatment of acute injuries such as low back pain but its effectiveness in treating this condition has not yet been verified. Objectives: To determine the effectiveness of a menthol cooling gel combined with anti-inflammatory herbs compared to a menthol gel and a placebo gel in the treatment of acute non-specific low back pain. Method: A double-blinded placebo controlled clinical trial (n = 60) was conducted. Each participant was randomly allocated into one of three treatment groups consisting of a minimum of 20 participants between the ages of 18 and 40 who met the study criteria. Informed consent was obtained from the participants prior to their participation in the study. At the initial consultation baseline measurements (pain rating, disability and pressure pain threshold) were taken and the respective treatments (menthol with anti-inflammatory herb, menthol or placebo gel) were administered. Participants were instructed on how to apply the gel at home and were requested to apply it three times a day for one week. Statistical analysis was performed using repeated measures ANOVA for inter- and intra-group analysis with one way ANOVA and chi square tests being used to compare baseline values. A p-value < 0.05 was considered to be statistically significant. The study received ethical clearance from the Durban University of Technology Institutional Research Ethics Committee (REC 81/13). Results: No significant differences were observed between the groups at baseline assessment, indicating that the groups were comparable. Participants were instructed on how to apply the gel at home and were requested to apply it three times a day for one week. Follow up appointments for data collection was scheduled at days three or four and six. No statistically significant differences were observed between the three groups over time for pain (p = 0.95), disability (p = 0.903) or pressure-pain threshold (p = 0.824), with all groups showing improvement. All three groups showed clinically significant changes in pain from moderate to mild over the duration of the study but no clinically significant changes were noted in terms of pressure-pain threshold and disability. Conclusion: The results indicate that irrespective of whether or not the gel contains active ingredients there was an improvement in acute low back pain. Further research needs to be conducted to determine if tissue depth and the concentration of the active ingredients such as menthol are factors affecting the efficacy of this gel.

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2015. / AIM: The aim of the study is to determine the epidemiology of adolescents attending public high schools, in the Westville ward of the Pinetown School District, who present with a history of primary headaches. SUBJECTS: Adolescents between 14 and 19 years of age currently attending a public high school in the Westville Ward of the Pinetown School District. METHODOLOGY: Upon approval from the Department of Education (DoE) and principals of participating public high schools, an appropriate time-slot was identified in which the post-pilot questionnaire and letters of information and informed consent could be delivered to the scholars via the researcher. One class from Grade nine, Grade 10, Grade 11 and Grade 12, in each school, was randomly selected by a blind draw to participate in the study. A total of 460 completed informed consent and post-pilot questionnaires were collected and placed in separate sealed ballot boxes. All sealed ballot boxes were collected by the researcher. All post-pilot questionnaires were kept confidential and only seen by the researcher and supervisor. A code was allocated to each questionnaire before data was captured on a spreadsheet for data analysis by the chosen statistician. RESULTS: In total 460 questionnaires were utilised for statistical analysis. The results showed a high prevalence of Migraine-type headache (MTH) (17.2%) and Tension-type headache (TTH) (27.6%). However, no scholars were diagnosed with a Cluster-type headache (CTH). The majority of scholars (63.8%) did not seek medical attention or advice for their headaches. A history of experiencing headaches (p=<001), participation in sport (p=0.008), difficulty sleeping (p=<0.001) and sleep bruxism (p=0.007) were the only significant risk factors noted as statistically significant in this study. CONCLUSION: This study is consistent with previous studies on the high prevalence of primary headaches in an adolescent population. Primary headaches negatively affect the daily activities of adolescents; however, majority of adolescents do not seek medical attention or advice for their headaches.

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2015. / Background CrossFit is a workout program developed in 2000 which involves high intensity interval training coupled with resistance training elements of powerlifting and gymnastics. CrossFit has grown to include competitive events and there are an ever increasing number of affiliate gyms internationally. CrossFit’s greatest criticism is related to safety. There is limited published data on the exercise program. Aims The aims of this study were: to determine a retrospective cohort analysis of the demographic, injury and treatment profiles of participants at the 2013 United We Stand CrossFit Games who presented to the Durban University of Technology’s sports treatment facility; to determine the association, if any, between demographics and injury types; and, to provide any recommendations regarding the clinical record form used. Methods This study was a retrospective, quantitative, descriptive study on the chiropractic Student Sports Association’s report form in order to produce a retrospective cohort analysis of the injury and treatment profiles. Persons who made use of the chiropractic treatment facility at the 2013 United We Stand CrossFit Games were required to complete an informed consent form. A sixth year chiropractic student then filled in a Chiropractic Student Sports Association report form to record participant, complaint and treatment information. The study was not limited to competitors, but all persons who had access to the chiropractic treatment facility. These forms were then collated and data captured on the complaints which presented and were treated at the chiropractic treatment facility. Results The data collected revealed that 137 participants presented to the chiropractic treatment facility in 162 visits, with 263 complaints treated. The age range of the sample was between 18 and 43 years, with a mean age of 27.49 years. The majority of participants who presented to the CTF were competing athletes and just under half of the study sample reported to not having a history of previous injury. The study found that the lumbar region (20.9%), wrist/hand (14.4%), shin/calf (11.0%) and knee (10.2%) were the most commonly presented regions of complaint. The highest presenting mechanism of injury was that of overuse (22.4%) followed by running (19.0%). Acute injuries accounted for 72.20% of all injuries. With regards to diagnoses, myofascial trigger points made up 21.6% of all injuries, followed by muscle strains (19.7%). Facet syndromes of the spinal column accounted for 13% of diagnoses.It was shown that kinesiotape, manipulation, massage and ischemic compression were the top treatment interventions utilised. It was also shown that rest, ice and referrals were types of treatment that were not utilised. Due to statistical inconsistencies no significance tests were possible between demographic and injury characteristics. Recommendations were proposed in order to maximise the quality of data captured. Conclusion: The results add insight into the injuries presented and the treatment they acquired at the chiropractic treatment facility at a national CrossFit event. The most common injuries require investigation in both training and competitive environments. Various recommendations have been proposed for the record form used at sporting events in order to facilitate the collection of high quality data. / M

Submitted in partial compliance for a Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2016. / Introduction There is a worldwide need for research into headaches in order to improve and add to the current model of literature to develop more efficient management strategies for headaches. Headaches can present clinically similarly and present a diagnostic challenge. Currently it is not known what the clinical accuracy of headache diagnosis is or which management strategies chiropractors prefer to use in practice to manage certain headaches. The aim of this study was to investigate the diagnosis of certain headaches by chiropractors in the greater Durban area and to determine how certain headaches commonly treated by chiropractors were managed. Methodology Based on the quantitative paradigm, this is a descriptive questionnaire based study involving a population of 88 chiropractors practicing in the greater Durban area. The final sample size was 63, a response rate of 72%. The questionnaire was developed specifically for this study and was validated by an expert group and tested by a pilot study to ensure construct and face validity. Data regarding demographic information, diagnostic approach to cervicogenic headache (CEH), intracranial haemorrhage, meningitis, migraine (MEH) and tension type headache (TTH) and management of CEH, TTH and MEH was collected from the sample. SPSS version 22 was used to analyse the data. Descriptive statistics were reported in frequency tables. Continuous variables were compared between independent categories using one way ANOVA tests. Trends were shown in cross tabulations and interpreted descriptively where Chi square tests could not be calculated. Results The sample size consisted of 63 chiropractors in the greater Durban area, South-Africa, of which 49.2% (31) were male and 50.8% (32) were female. The mean age was 37 years (range 25 to 71 years). The majority of the sample had between six- to nine years of practice experience, with the majority being in full time practice (82.5% (52)). The majority (92.1% (58)) of the sample had graduated from DUT. Seventeen point five percent (11) of the sample had additional tertiary qualifications, the most common of which was a Master’s degree of Medical Sciences (Sports Medicine), with a total of 19 additional short courses being reported by 79.4% (50) of the sample. Seventy five point one percent (41) of the sample indicated usage of chiropractic specific journals, with 38.1% (24) of the sample indicating that these journals had an impact on the way they manage headaches in practice. Seventy seven point eight percent (49) of the sample attended health related conferences on a regular basis, with 38.1% (24) of the sample indicating that these conferences influenced their management of headaches in practice. Seventeen point five percent (11) of the sample had practiced internationally, with a range of international practice from one month to 12 years. The majority of the sample indicated that they practiced according to a combination of mixer and evidence based philosophy. The accuracy of diagnostic outcome for meningitis was 98.4% (62), TTH was 47.6% (30), MEH was 82.5% (52), CEH was 82.5% (52) and intracranial haemorrhage was 30.2% (19). The results for the management of CEH, TTH and MEH indicated that a minimum of 98.6% (62) would adjust a patient with these headaches; the sample predominantly preferred application of specific adjustments to fixated segments in the cervical and thoracic spine. A minimum of 66.7% (42) regarded spinal manipulative therapy (SMT) as the primary focus of treatment across all three headaches. The most commonly selected modality to be used in conjunction with SMT was massage therapy (with a minimum selection frequency of 68.3% (43) across CEH, MEH and TTH). Massage therapy was the most commonly selected modality to be used when SMT is contra-indicated (minimum selection frequency of 61.9% (40) across CEH, MEH and TTH). A minimum of 98.4% (62) of the sample indicated that they would treat MFPTs if associated with headaches, most commonly using dry needling. For the majority of the sample, the interval of choice for a second appointment was two to three days and the number of treatments expected for relief of symptoms was two to three treatments. Further investigations were considered necessary by the majority of the sample after seven days without any relief of symptoms. The majority of the sample recommended pain free care. Regarding patient advice and education, there was agreement on postural and ergonomic advice, home stretching, stress management techniques and proprioceptive exercises. If treatment goals were not obtained, the majority of the sample agreed to change the treatment plan, reassess all of the previous findings and if necessary refer the patient to another non-chiropractic health care provider. Conclusion Based on the case scenarios used in this study, meningitis, CEH and MEH were accurately diagnosed by the majority of the sample. There appeared to be some confusion with regard to the diagnosis of TTH as nearly half of the sample confused it for CEH. The accuracy with regard to the diagnosis of intracranial haemorrhage was concerning as the minority of the sample correctly diagnosed this condition. A relatively similar approach was used by chiropractors to treat headaches, with relatively little change in the treatment options between CEH, TTH and MEH. Most of the treatment methods, used by most of the sample, have moderate evidence for efficacy in treatment of musculoskeletal conditions. The management options chosen by the majority of the sample could be of potential benefit for the management of the respective headaches. Few differences were noted with regard to the impact of demographic information on the diagnostic outcome and management approaches. Some, but not enough, evidence indicates that the older participants provided less accurate diagnoses. The headaches which were less accurately diagnosed possibly due to an age difference were meningitis, TTH and MEH. With regard to management of headaches the only statistically significant differences were noted for the management of TTH for which age appeared to influence the specificity of adjustments used in TTH. / M

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Department of Chiropractic, Durban University of Technology, Durban, South Africa, 2016. / Aim: To determine the intra- and inter-examiner reliability of the radiographic assessment of the cervical lordosis of asymptomatic adult males. Participants: Eighty lateral plain film radiographs of the cervical spine of asymptomatic males aged 18-45 years (taken in a previous study) were utilised for this study. However, due to the obstruction of the C7 vertebral body by the trapezius muscle, the examiners were unable to assess the CL on all 80 plain film radiographs. Three examiners took part in the study viz. Examiner One who was a qualified chiropractor with three years of clinical experience, Examiner Two who was a qualified chiropractor with six years of clinical experience and Examiner Three who was a chiropractic master’s student. Methodology: The initial set of assessments of the CL using the C1-C7 and C2-C7 modified Cobb methods was completed by Examiner One and captured on an Excel spread sheet for Round One. The procedure was then repeated for Examiners Two and Three. The process was repeated for the second set of assessments (Round Two). Each examiner was given a maximum of two weeks to complete their assessments for each round. The data was statistically analysed using SPSS 22.0 and Stata 13. Descriptive data was presented in tables as mean and standard deviation at a 95% confidence interval while intra- and inter-examiner reliability was determined using the Kappa coefficient. Results: The mean (± SD) CL values obtained by each examiner using the C1-C7 modified Cobb method for Round One was: Examiner One: 45.6˚ (± 10.4˚) (n = 70), Examiner Two: 44.0˚ (± 11.0˚) (n = 75) and Examiner Three: 43.8˚ (± 12.0˚) (n = 72). The mean (± SD) CL values obtained by each examiner using the C1-C7 modified Cobb method for Round Two was: Examiner One: 46.7˚ (± 10.7˚) (n = 72), Examiner Two: 43.3˚ (± 11.1˚) (n = 74) and Examiner Three: 43.8˚ (± 11.5˚) (n = 72). The mean (± SD) CL values obtained by each examiner using the C2-C7 modified Cobb method for Round One was: Examiner One: 15.9˚ (± 9.2˚) (n = 72), Examiner Two: 22.6˚ (± 9.7˚) (n = 75) and Examiner Three: 17.2˚ (± 9.7˚) (n = 72). The mean (± SD) CL values obtained by each examiner using the C2-C7 modified Cobb method for Round Two was: Examiner One: 16.3˚ (± 9.4˚) (n = 72), Examiner Two: 20.5˚ (± 9.0˚) (n = 74) and Examiner Three: 16.9˚ (± 9.2˚) (n = 72). The intra-examiner reliability obtained by each examiner using the C1-C7 modified Cobb method for Round One and Round Two was: Examiner One: K = 0.16, Examiner Two: K = 0.11 and Examiner Three: K = 0.16. The intra-examiner reliability obtained by each examiner using the C2-C7 modified Cobb method for Round One and Round Two was: Examiner One: K = 0.21, Examiner Two: K = 0.04, Examiner Three: K = 0.22. The inter-examiner reliability obtained by each examiner using the C1-C7 modified Cobb method for Round One and Round Two respectively was: Examiner One vs Examiner Two: K = 0.03; K = 0.09, Examiner One vs Examiner Three: K = 0.19; K = 0.15, Examiner Two vs Examiner Three: K = 0.03; K = 0.08. The inter-examiner reliability obtained by each examiner using the C2-C7 modified Cobb method for Round One and Round Two respectively was: Examiner One vs Examiner Two: K = 0.00; K = 0.01, Examiner One vs Examiner Three: K = 0.19; K = 0.11, Examiner Two vs Examiner Three: K = 0.02; K = 0.05. There was a significant difference in the intra-examiner findings for both the modified Cobb methods (p < 0.05). Using the C1-C7 modified Cobb method, there was a significant difference in the inter-examiner reliability findings between all three examiners for both rounds (p < 0.05). There was no significant difference in the inter-examiner findings of the CL using the C2-C7 modified method between Examiner One versus Examiner Two for Round One (p = 0.33) and Round Two (p = 0.23) but there was a significant difference in the findings between Examiner One versus Examiner Three (p < 0.05) and between Examiner Two versus Examiner Three (p < 0.05) for Round Two only. Conclusion: The results of this study are in agreement with those of a previous study which reported that the C1-C7 modified Cobb method over-valued the magnitude of the curve while the C2-C7 modified Cobb method under-valued the curve. A significant difference in the intra-examiner findings suggests that recall bias did not significantly affect the assessments while inter-examiner findings suggest that experience and skill of the examiners as well as assessments that require drawing of lines and measuring of angles might lead to differences in the results obtained. Further studies which would utilise a large number of digitised radiographic images from both asymptomatic and symptomatic individuals are required to confirm the findings of this study. / M

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Department of Chiropractic, Durban University of Technology, Durban, South Africa, 2016. / Background Literature has shown that clinical and radiological diagnoses do not always correlate in patients with neck pain (Ferrari and Russel, 2003; Peterson and Hsu, 2004). It is not known if this applies to the Chiropractic Day Clinic (CDC) at the Durban University of Technology (DUT) and if the radiological diagnosis leads to a change in the patient’s initial management plan. The impact of cervical spine plain film radiographs will therefore be investigated in the diagnosis and management of patients that presented with neck pain to the CDC at the DUT. It is also not known whether the reason for referral for cervical spine plain film radiographs is always indicated as per the indications in the clinic handbook and radiological referral guidelines. Objectives Objectives were: (1) To determine the suspected pre-radiographic clinical diagnosis and management of the selected clinical records prior to referral for cervical spine plain film radiography; (2) To record the reasoning to send for cervical spine plain film radiographic imaging and to establish whether these are in line with proposed guidelines for referral as found in the literature; (3) To determine the relationship between the suspected pre-radiographic clinical and the radiological diagnoses of patients with neck pain; (4) To determine the number of incidental findings in the selected patients’ plain film radiographs; (5) To determine any change in the pre-radiographic clinical diagnoses and management following radiological reporting of the selected patient’s plain film radiographs. Method This was a quantitative, retrospective, clinical study. The archives at the CDC at the DUT were searched for cervical spine plain film radiographs between 1 January 1997 to 31 December 2013 and these were matched with the corresponding clinical records. After applying the inclusion and exclusion criteria, 73 records were included in the study. The patient’s personal information was coded to ensure confidentiality (Appendix A) and specific clinical and radiological information was recorded (Appendix B). Statistical analysis included the use of frequency counts, percentages, mean, standard deviation and range for the descriptive objectives. Results A total of 73 clinical files and corresponding plain film radiographs were assessed. The mean age of the patients was 44 years. The gender distribution was 64.4% (n=47) females and 35.6% (n=26) males. The most frequent primary radiological diagnosis was loss of lordosis at 41.1% (n=30) followed by cervical spondylosis at 35.6% (n=26) and old cervical spinal trauma at 12.3% (n=9). Sixty four percent (n=47) of patients in this study were sent for cervical spine plain film radiographs after their initial clinical consultation. Reasons that are not considered relevant indications for plain film radiographic referral were present in 46.2% (n=34) of cases; these described non-specific mechanical disorders. The most common reason for plain film radiographic referral was due to positive orthopaedic tests 57.5% (n=42). A total of 27.4% (n=20) of clinical files reviewed had a change in their initial clinical diagnosis and 72.6% (n=53) of these patients had no change in diagnosis. All of the post-radiographic clinical diagnoses were non-specific mechanical conditions. Numerous treatment modalities were utilized by the students with the most common pre-radiographic treatment being soft tissue therapy at 63.0% (n=46). A total of 75% (n=55) of patients had a change of treatment after plain film radiographs were performed and spinal manipulative therapy (SMT) was the main treatment added in 41% of cases. Conclusion Cervical spine plain film radiographs have little impact on the diagnosis of patients with non-specific mechanical neck pain without red flags. It was however found that plain film radiographs had an impact on the management in the majority of cases, especially with an increase in SMT use after plain film radiographs. / M

Thesis (M.Tech.: Chiropractic)-Dept. of Chiropractic, Durban Institute of Technology, 2005 96, [20] leaves / Strengthening of the rotator cuff muscles forms an integral part of any rehabilitation programme for the shoulder. Shoulder rehabilitation programmes which incorporate early motion and emphasize strengthening, have a lower incidence of recurrent subluxations and dislocations. If cervical manipulation were proven to increase the strength of the rotator cuff muscles, then this could be used to develop and implement more effective treatment and rehabilitation protocols for patients with musculoskeletal painful shoulders and rotator cuff pathologies, and therefore provide future patients with more effective health care. Studies have shown consistent reflex responses associated with spinal manipulative treatments. These reflex responses have been hypothesized to cause the clinically beneficial effects of decreasing hypertonicity in muscles, pain reduction and increasing the functional ability of the patient, and although spinal manipulation has been shown to affect muscle strength, it has not been extensively researched and it is unclear whether increased muscle strength is yet another reflex effect of manipulation. As the rotator cuff is innervated by nerves arising from the mid and lower cervical spine, it is theorised that dysfunction of the spinal joints adversely affects nerve endings, causing inhibition of nerve function and affecting the rotator cuff. This is congruent with research which describes how there could be a decrease in muscular activity due to interference with the nerve supply of a muscle by means of a spinal joint fixation. In light of this, one could hypothesize that removal of a cervical joint dysfunction by manipulation, could increase motor unit recruitment and muscular activity of the muscles supplied by that cervical level and therefore possibly strengthen the muscles involved. Therefore the aim of this study was to determine whether cervical manipulation could contribute to the strengthening process of the rotator cuff. / M
