M.Tech. (Chiropractic) / Purpose: The effectiveness of cervical spine adjustments for improving spinal function and relieving pain has been well established. However, the mechanisms responsible for these changes after spinal adjustments are still being researched. Further scientific evidence regarding the neurological and physiological effects following spinal adjustments is warranted. Evidence suggesting that spinal dysfunction has an effect on central neural processing is growing. A number of palpation from the first to the sixth visit. The seventh visit consisted of gathering data only. Results: Clinical and statistical improvements in the entire group were shown over the course of the treatment with regards to cervical spine range of motion, touch pressure threshold and neck pain and disability. Conclusion: The results show that lower cervical spine adjustments do have an effect on touch pressure threshold, cervical spine range of motion and neck pain and disability in patients with chronic cervical facet syndrome. Touch pressure threshold returned to optimal function, cervical spine range of motion increased and neck pain and disability decreased in all participants over time. authors have suggested that spinal dysfunction may lead to altered sensory input to the central nervous system (Murphy and Taylor, 2008). Aim: The aim of this study was to determine the effect of C6, C7 and T1 spinal adjustment therapy on those individuals with posterior neck pain due to chronic cervical facet syndrome and its influence on touch pressure threshold, neck pain and disability as well as cervical spine range of motion. Method: This study consisted of a single group of thirty participants between the ages of eighteen and fourty-five. The potential participants were examined and accepted according to the inclusion and exclusion criteria. The only method of treatment administered to each participant was cervical spine adjustments delivered to restricted C6, C7 and Tl segments in the lower cervical spine. Subjective and objective findings followed. Procedure: Treatment consisted of seven visits. Subjective and objective data was taken at the first, fourth and seventh visit. Objective data consisted of cervical spine range of motion readings taken using a Cervical Range of Motion measuring instrument (CROM), and touch pressure threshold results obtained via the Semmes Weinstein monofilaments. Subjective data was taken in the form of a Vernon Mior Neck Pain and Disability Index. Cervical spine adjustments were applied to restricted segments in the lower cervical spine (C6, C7, Tl), identified through motion

Methodology: This study was a randomised single-blinded clinical trial which consisted of 40 participants residing in the eThekwini municipality, divided into two groups of 20 each. The participants were randomly assigned using concealed allocation to one of two treatment groups of 20 viz. Impulse iQ® Adjusting Instrument (IAI) trigger point therapy group and ischaemic compression (IC) group. Neck pain level was determined using a numerical pain rating scale (NRS). Degree of lateral flexion (LF) was determined by a cervical range of motion (CROM) goniometer. Pain pressure thresholds (PPT) were measured with a pain pressure algometer. The effect of neck pain on participants’ activities of daily living was assessed using the Canadian Memorial Chiropractic College (CMCC) Neck Disability Index (NDI). The participants’ overall perception of improvement since the initiation of treatment was assessed using the Patients Global Impression of Change (PGIC). The participants received three treatments over a two and half week period with the fourth consultation being used for the final subjective and objective measurements. Results: Repeated measures ANOVA testing was used to examine the intra-group effect of time and the inter-group effect of treatment on the outcomes of NRS, algometer readings and CROM goniometer measurements. Profile plots were used to assess the direction and trends of the effects. An intra-group analysis revealed that, objectively and subjectively, all groups responded positively to treatment over time, with no significant time-group interaction. It was noted that there was a higher rate of improvement in IAI Group with respect to algometer readings over time; however, this difference was not statistically significant. Conclusion: This study concluded that neither IAI nor IC is more effective than the other with respect to participants’ pain perception and CROM. However, the IAI was more effective on pain pressure threshold. Based on the results collected from this study, both therapies can used in the treatment protocols of neck pain associated with MFTPs. / M

Dissertation submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic at the Durban Institute of Technology, 2008. / Purpose Cricket fast bowlers are prone to the development of Myofascial pain syndrome and in particular active myofascial trigger points in their rotator cuff muscles of the shoulder joint (Scott, et al. 2001). This is due to the severe stresses placed upon the muscles, bones and joints of the shoulder as a result of the high velocity throwing action (Bartlett, et al.1996). In muscles containing active myofascial trigger points a decrease in the stretch range of motion as well as the maximal contractile force is noted, these two factors may negatively affect the speed at which a fast bowler deliver the ball (Travell, Simons and Simons, 1999). Dry needling is viewed as the most effective means of deactivating myofascial trigger points leading to in increase in both the contractile force and range of motion of the affected muscle, which could increase the speed at which the bowler delivers the ball (Wilks, 2003). The aim of the study was to determine the immediate effect of dry needling active myofascial trigger points of the rotator cuff on bowling speed in action cricket fast bowlers. Method The study consisted of 40 participants (randomly split into two equal groups of 20) each with shoulder pain of a myofascial origin. Group A (intervention group) received the dry needling intervention in their most tender active myofascial trigger point. While participants in Group B (control group) received no treatment. Bowling speeds were measured both before and after the intervention, to determine its effect on bowling speed. IV Data was entered into MS Exel spreadsheet and imported into SPSS version 15 (SPSS Inc.,Chicago, Iiiinois, USA), which was used for data analysis. Paticipants were evaluated on bowling speed, Algometer readings and Numerical pain rating Scale (NRS) both pre and post intervention. Participants were also asked if they believed the intervention increased, decreased or had no effect on their bowling speeds. Two sample t-test was used to compare baseline values between the groups. A repeated measure ANOVA was used to compare the rate of change of each outcome over time in the two groups. Pearson’s correlation analysis (intra-group) was used to assess the strength and magnitude of correlations of the changes in the outcomes. The McNemar – Bowker test and Weighted Cohen’s kappa statistics were calculated to assess agreement between perceived and actual levels of change. Results A significant treatment effect was observed in the intervention group were an increase in bowling speed, algometer readings as well a decrease in Numerical pain rating scale(NRS) scores was observed. There was also a perceived increase in the speed the participants delivered the ball in the intervention group. No significant changes were observed in the control group. The findings of this study indicate that dry needling as a treatment modality would be beneficial to fast bowlers in not only increasing their speeds but also the pain experienced as a result of active myofascial trigger points.

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2018. / Aim The aim of this study was to determine the concurrent validity of an isiZulu Bournemouth Questionnaire in comparison to its English counterpart. Methodology This quantitative correlational study compared the isiZulu version of the Bournemouth Questionnaire to its English counterpart, (consisting of three sections: back, neck and musculoskeletal). The study employed a design where subjects were compared to themselves. A sample of 120 volunteers over the age of 18 years, who were literate in both English and isiZulu took part in the study. Whether the participant was symptomatic or asymptomatic was not of concern. Using a randomised list, the participants were administered one of the two versions of the questionnaire to be completed first, the second and alternate questionnaire was administered after an interval of at least 20 minutes. Results Of 120 paired questionnaires, 107 completed pairs were returned, resulting in a response rate of 89.2%. Results, using Cronbach-α (α= 0.05) with subsequent testing using the Kaiser-Meyer-Olkin Measure of Sampling Adequacy and Bartlett’s Test of Sphericity, revealed that the questionnaires, in toto, had high levels of correlation. The relationship between the isiZulu and the English questions revealed a positive and high correlation using Kendall’s tau-b which was statistically significant (τb > 0.55, p = 0.000), although there were isolated instances of statistical difference between individual pairs of questions in respect to age, gender, site, primary language and level of education. Conclusions The study found that the isiZulu version of the Bournemouth Questionnaire showed concurrent validity with its English counterpart, and recommendations were made for the clinical application of the isiZulu version as a means of refining the interpretation of disjunct question pairs. / M

M.Tech. (Chiropractic) / Aim of this study was to compare which treatment either Proprioceptive Neuromuscular Facilitation or chiropractic manipulation, whether by itself or in combination, was more effective and beneficial in the treatment of mechanical neck pain. The effectiveness was measured by the use of a Visual Analogue Scale, Vernon- Mior Neck Pain and Disability Index questionnaire and the measurement of cervical spine range of motion using an analogous cervical spine range of motion inclinometer (CROM). The questionnaire and the measurements were taken prior to the treatments at the first, fourth and seventh consultations.Thirty participants who met the inclusion criteria were randomly placed into three groups of equal size (10 participants each). Group one received a Proprioceptive Neuromuscular Facilitation (PNF) stretching protocol to the cervical spine. Group two received a chiropractic manipulation to the cervical spine. Group three received a combination treatment, first receiving chiropractic manipulation and then a PNF stretching protocol to the cervical spine. Participants were treated six times out of a total of seven sessions, over a maximum of a three week period.Subjective data was collected at the beginning of the first, fourth and seventh consultations. This was done by means of a Visual Analogue Scale and a Vernon-Mior Neck Pain and Disability Index Questionnaire, in order to assess pain and disability levels. Objective data was collected by means of measuring cervical spine range of motion using a cervical range of motion (CROM) inclinometer. Analysis of collected data was performed by a statistician from STATKON, a department of the University of Johannesburg.Clinically significant improvements in group 1, group 2 and group 3 were noted over the duration of the study with reference to pain and disability. Statistically significant changes were seen in all three groups with reference to pain and disability. Group 3 was shown to improve the most with regard to pain and disability. Group 1 had statistically significant improvement with regard to cervical range of motion in the ranges of left and right rotation. Group 2 experienced a decrease range of cervical motion with regard to extension. As the study consisted of a small group of participants further, more extensive studies are needed...

M.Tech. (Chiropractic) / The aim of the study was to compare the efficacy of treating the active levator scapulae trigger point (TP1) with either chiropractic adjustments combined with ischemic compression or chiropractic adjustments combined with ultrasound therapy in physically active people in order to determine which of the two treatment protocols was superior.This study was a comparative study consisting of two groups of fifteen participants each. Participants were between the ages of eighteen and forty-five and there was an equal male to female ratio. Prior to becoming a participant in this study individuals were assessed according to the inclusion and exclusion criteria. The International Physical Activity Questionnaire, a clinical case history, full physical examination, a cervical regional examination and examination of the levator scapulae muscle for an active central trigger point (TP1) were completed. The method of treatment for each participant was determined by random group allocation. Group 1 received cervical spine chiropractic adjustments combined with ischemic compression to the active levator scapulae trigger point. Group 2 received cervical spine chiropractic adjustments combined with ultrasound therapy to the active levator scapulae trigger point. Subjective and objective readings were based on the above treatment protocols.Treatment consisted of seven consultation sessions over a three week period. There were six treatment visits with the seventh visit used only for data collection. There were two treatments each week with at least two days in between visits. The third week consisted of three visits with the last visit used only for data collection. Subjective data was collected from the Vernon-Mior Neck Pain and Disability Index Questionnaire and the Numerical Pain Rating Scale. Objective data was collected from the pressure algometer readings. Subjective and objective data was collected before treatment on the first and fourth visits and on the seventh final data collection visit. Analysis of the data collected was done by a statistician. The chiropractic adjustments used were based on motion palpation findings on the treatment visits and re-assessed on each visit.Clinically significant improvements regarding neck pain and disability and trigger point severity were seen in both Group 1 and Group 2 over the three week period. Group 2 showed greater improvements in all subjective and objective readings over the three weeks compared to Group 1.

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2017. / Aim: There is a paucity in the literature regarding the effectiveness of the Impulse Adjusting Instrument® (IAI) in treating myofascial trigger points (MFTPs) and regarding the effectiveness between dry needling and the IAI in the treatment of MFTPs. There are many limitations and an array of contraindications for dry needling. Therefore, an alternative method should be sought as this will be beneficial to the patient. Thus, the aim of this study was to determine the effectiveness of the IAI compared to dry needling in the treatment of MFTPs found in the upper trapezius muscle. Methodology: This study was a randomised single-blinded clinical trial. This study consisted of 41 participants between the ages of 18 and 40 who were divided into two groups. The participants were randomly allocated into their respective groups using a blinded allocation method that was drawn up by the statistician. Groups were divided into dry needling (Group one (n=18)) and IAI (Group two (n=23)) treatment groups. Subjective neck pain level was determined using a numerical pain rating scale (NRS). The neck disability index (NDI) subjectively assessed the effect neck pain had on the participants’ activities of daily living before and after treatment. The Patients Global Impression of Change (PGIC) tool was used to determine the participants’ subjective impression of treatment outcomes since the beginning of the treatment. Objective pain pressure thresholds (PPT) were measured with an algometer. Objective cervical range of motion (CROM) in lateral flexion (LF) was measured with a goniometer. Each participant had four visits over a two week period, which included three treatments and a final visit for final measurements. Data was analysed using IBM SPSS version 23. Repeated measures ANOVA was used to examine the effect on each outcome measure. Directional trends in effectiveness were drawn up using profile plots to assess the direction and trends of the effects. A p value of < 0.05 was considered to be statistically significant. Results: Intra-group and inter-group statistical analysis revealed all subjective measurements improved in both groups with no significant differences between the groups. With respect to objective measurements, there was no statistical improvement in LF CROM and dry needling had no improvement in PPT. Impulse Adjusting Instrument trigger point therapy showed an increase in PPT, however, when compared to dry needling there was no statistical difference in PPT. Conclusion: The conclusion for this study states that the trends in each of the outcomes suggest that the IAI is as effective as dry needling for the treatment of MFTPs. / M

M.Tech. (Chiropractic) / Neck pain is a common and costly complaint in society and many are made to believe that their neck pain is caused by pinched nerve, compressed disk, arthritis or displaced cervical vertebrae, when in reality the pain may be solely due to referral from myofascial trigger points in overworked or traumatized muscles of their upper back and shoulders. Travel and Simons (1999) demonstrated trapezius muscle of the neck, back and shoulder as the main cause of mechanical neck pain and stiffness. The aim of this study was to compare the effects of trigger point therapy using an activator instrument versus myofascial dry needling in combination with cervical spine adjustment in the treatment of those with acute or chronic neck pain associated with active trigger point 1 (TrP 1) or trigger point 2 (TrP 2) of upper trapezius muscle, with regards to pain and disability, pressure pain threshold and cervical spine range of motion. The clinical study consisted of forty participants, from the ages of 18 and 45, randomly allocated into two groups of twenty individuals each. Potential participants were examined and accepted based on inclusion and exclusion criteria. Group 1 received activator trigger point therapy to upper trapezius TrP 1 or 2 with chiropractic adjustment to restricted segments of the cervical spine, and group 2 received myofascial dry needling of upper trapezius TrP 1 or 2 with chiropractic adjustment to restricted segments of the cervical spine. Participants were treated four times over a period of two weeks. Subjective data was collected using the Vernon-Mior Neck Pain and Disability Index and a Visual Analog Scale. Objective data was collected using an algometer to measure pressure pain threshold of trapezius TrPs muscles, and a goniometer to measure cervical spine range of motion. All data was collected at the first and third visits prior to treatment, and at the fifth visit. The statistical analysis was conducted using nonparametric tests. Friedman’s test was used to assess whether neck pain, disability, cervical spine range of motion and pressure pain threshold varied over the three time intervals. Wilcoxon Signed Ranks Pair test was used for assessment of comparability of the results in each group separately, and the Mann-Whitney U test was used for comparison of the accumulated data in the two groups.

M.Tech. / Purpose: This study aims to compare the effects of Chiropractic manipulative therapy of the cervical spine in conjunction with SpiderTech therapy in the treatment of chronic neck pain with regards to pain, disability and cervical spine range of motion. Method: This study consisted of two groups of 15 participants between the ages of eighteen and forty, ensuring equal male to female and age ratios. The potential participants were examined and accepted according to the inclusion and exclusion criteria. The method of treatment administered to each participant was determined by group allocation. Group 1 received chiropractic manipulative therapy to restriction(s) of the cervical spine, with the SpiderTech Neck Spider applied to the posterior aspect of the neck. Group received chiropractic manipulative therapy to restriction(s) of the cervical spine only. Procedure: Treatment consisted of 6 treatment sessions with an additional follow up consultation, with two consultations being performed per week interval. Subjective data and objective data was taken at the beginning of the first, fourth and seventh sessions. The subjective data collected was in the form of a Numerical Pain Rating Scale and a Vernon- Mior Neck Pain and Disability Index. Objective data consisted of cervical spine range of motion readings taken using a Cervical Range of Motion measuring instrument (CROM). Analysis of collected data was performed by a statistician. The Chiropractic manipulative techniques used were based on restrictions identified during motion palpation and were applied at the first six consultations, with the seventh consultation consisting of data gathering only. Results: Statistically significant changes were noted in group 1 and group 2 with reference to pain and disability, and in group 1 and group 2 with reference to cervical spine range of motion. Clinically significant improvements in group 1 and group 2 were noted over the duration of the study with reference to pain, disability and cervical spine range of motion. However, the combined treatment group (group 1) had a clinically greater effect than that of the manipulation only group. Conclusion: The results show that both Chiropractic manipulative therapy, as well as Chiropractic manipulation in conjunction with the SpiderTech Neck Spider are effective treatment protocols in decreasing pain and disability and increasing cervical spine range of motion in patients with chronic neck pain. However, neither treatment protocol proved to be preferential. When compared to Chiropractic manipulative therapy alone, SpiderTech therapy in conjunction with Chiropractic manipulative therapy has a clinically larger effect on neck pain, disability and range of motion of the cervical spine.
