Dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic in the Faculty of Health at Technikon Natal / Myofasciitis IS a very common yet misunderstood problem. There are many treatments available yet there is no research to substantiate which of the many treatments available is the most effective (Travell and Simons 1983:6). The purpose of this study was to investigate the relative effectiveness of Cryotherapy versus moist heat in the treatment of myofasciitis of the shoulder girdle muscles. Patients for this comparative, randomized clinical trial were obtained by consecutive sampling. Any patient between eighteen and fifty-five presenting to the Chiropractic Clinic at Technikon Natal with neck pain, upper back pain or shoulder paIn was considered a potential candidate. Thirty patients underwent a screening process to assess their viability for the study. This screening procedure consisted of questions regarding the pattern of pain referral and of palpation of the relevant zones for muscle spasm, twitch responses, patient jump sign and/or referred palll. The thirty patients were randomly divided into two groups of fifteen. One group received cold and passive stretching and the other group received moist heat and passive stretching. Each patient was treated five times within a three week period. Thereafter a follow-up appointment was scheduled one month after the final treatment to assess the long term effects of the treatments . The subjective information was questionnaires: (1) the CMCC Neck Numerical Pain Rating Scale-l0l assessed us Ing three Disability Index, (2) the and (3) the Short Form McGill Pain Questionnaire. These three forms were used to subjectively assess vanaus aspects of the patient's pain. Patients were required to fill these forms out at the first and / M

Athletes who perform overhead throwing sports such as: baseball, javelin, swimming/waterpolo and tennis, are susceptible to sustaining a micro-traumatic injury of the rotator myotatic unit of the shoulder, owing to repetitive high velocity mechanical stress placed on the shoulder at the extreme ranges of motion. The inherent structure of the shoulder, with three external rotators and five internal rotators, causes a muscle imbalance before an activity, such as throwing occurs, and this can predispose an athlete to Repetitive Stress Injuries (RSI) as a result of overuse or overload. The incidence and activation of TrP's in shoulder muscles can be accounted for on the basis of mechanical stress such as overuse / overload and thus could change muscle fiber co-ordination (muscle activity) and precipitate a painful lesion. It can be seen in current literature that TrP's produce a number of signs and symptoms such as: spasm of other muscles, weakness of involved muscle function, loss of co-ordination and decreased work tolerance of the involved muscle . Therefore the TrP's present in the shoulder rotator unit could contribute to changes in internal/external rotation ratios in over head athletes, and thus by deactivating or eliminating these TrP's, it is possible that these ratios may be / M

A dissertation submitted in partial compliance with the requirements for a Master's Degree in Technology: Chiropractic, Technikon Natal, 1999. / The purpose of this study is to determine the relative effectiveness of (Contract-Relax- Agonist-Contract) CRAC stretching, a component of Proprioceptive Neuromuscular facilitated (PNF) stretching, as opposed to static stretching in the treatment of active myofascial trigger points of the shoulder girdle and neck muscles. This was a randomised clinical trial consisting of two groups. Group A received static stretching as their treatment protocol and Group B received PNF (CRAC) as their treatment protocol. Each group consisted of fifteen people between the ages of 18 and 55 who were randomly allocated to their respective groups. It is hypothesised that PNF (CRAC) stretching would be relatively more effective than Static stretching in the treatment of active myofascial trigger points of the shoulder girdle and neck muscles. Subjects diagnosed with active myofascial trigger points in the Trapezius, Infraspinatus and Rhomboid muscles were included in the study. The treatment regime consisted of a course of five treatments spread over a period of two weeks and then a one - month follow up consultation. Subjective and objective measurements were taken at the first, fifth and follow up consultations. Subjective data consisted of the Short Form McGill Pain Questionnaire, the CMCC Neck Disability Index and the Numerical Pain Rating Scale -101. The objective data was collected by means of algometer and goniometer measurements. This data was used to perform statistical analysis using the non-parametric Wilcoxin signed-rank test and the Mann Whitney unpaired test to compare intra-group and intergroup data respectively, at a 95% confidence level. This study suggests that both static and PNF (CRAC) stretching are effective in the treatment of active myofascial trigger points. However there is no clinical statistical difference between these two treatments. Further studies with a larger sample size are needed to clearly evaluate the use of stretching in the treatment of active myofascial trigger points. / M

Thesis (M.Tech.: Chiropractic) -Dept. of Chiropractic, Durban Institute of Technology, 2002 / The purpose of this randomized controlled clinical trial was to investigate the relative effectiveness of proprioceptive neuromuscular facilitation (PNF) versus ultrasound therapy for the treatment of Temporomandibular joint (TMJ) dysfunction caused by masticatory myofascial trigger points, in terms of subjective and objective clinical findings.

A dissertation presented to the Faculty of Health Sciences at the Durban University of Technology in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, 2009 / Introduction: The aetiology of Temporomandibular Joint Dysfunction (TMJD) is not fully understood and the treatment of TMJD is controversial. Most treatment plans are based on postulated aetiology. Treatment plans currently range from pharmacological to surgical and occasionally physical therapy is also used for any myofascial component. Myofacial Trigger Points (MFTP’s) in the head and neck region have similar pain referral patterns as TMJD and there is overlap in aetiology and epidemiology. If correlation can be proved to exist between the severities of TMJD and MFTP’s then the treatment of MFTP’s can potentially decrease the severity of TMJD and then the more radical treatments can be avoided. Objectives: To determine whether TMJD was present and establish severity. To locate any MFTP’s in the Sternocleidomastiod (SCM), Temporalis, Masseter, Posterior Cervical (PC), Lateral and Medial Pterygoid muscles and determine their severity. Methods: A random sample of 25 participants were evaluated. A p value <0.05 was considered as statistically significant. Quantitative variables were summarized using median, inter-quartile range and range due to skewness of distribution, while categorical variables were described using frequency distributions and bar charts. Spearman’s nonparametric correlation analysis, and curve estimation were used to determine the existence of a relationship between TMJ severity and MFTP severity. A scatterplot was used to graphically assess the relationship. Conclusion: The results suggested that the participants were actually chronic neck pain suffers that developed TMJD over the long term as a result of chronic neck pain changing the kinematic biomechanics or as a result of a completely different and independent event as suggested by Foreman and Croft (1995).

Dissertation submitted to the faculty of health in partial compliance with the requirements for the Masters Degree in Technology: Chiropractic, at the Durban University of Technology, 2008 / Introduction: Myofascial Pain Syndrome (MPS) is a painful and prevalent muscular condition. It is characterized by the development of Myofascial trigger points (TrPs) that are locally tender when active and which can refer pain through specific patterns to other areas of the body distal from the trigger point. There exist many types of treatments for MPS of which dry needling is one of the most effective forms. However, a very common side-effect experienced is postneedling soreness, which when compared to trigger point injections are more painful, with respect to both intensity and duration. Studies have shown that the exact cause of post-needling soreness has not been clearly documented. Action Potential Simulation (APS) Therapy operates using a direct electric current (DC) on muscles. It stimulates action potentials that are stronger than the natural nerve impulses. It operates on a similar principle to the gate control theory of Melzack and Wall (1988) which results in the inhibition of nociceptive signals. Stimulation by the APS unit creates a normal action potential that restores the inherent biochemical processes in the region. This low to medium frequency current (below 150 Hz) has been reported to alleviate pain, decrease inflammation, enhance blood circulation and aid in wound and bone fracture healing. Methodology: This study was designed as a prospective, randomised, controlled experimental investigation. Sixty subjects were randomly allocated into three equal groups of 20 subjects each. Group One received the fanning dry needling technique; Group Two received a combination of fanning dry needling plus APS Therapy. Group Three was the control group in which the subjects were treated with fanning dry needling with „Sham‟ APS Therapy. Algometer and Numerical Pain Rating Scale 101 (NRS 101) readings were taken immediately before and after the dry needling procedure and again at the follow-up visit 24 hours later. Subjects used a 24-hour pain diary and the NRS 101 scale which was filled out at 3 hour intervals, to record any post-needling soreness. Results: An intra-group analysis revealed that, objectively and subjectively, all groups experienced some degree of post-needling soreness, which deceased significantly over time. This decrease of pain was not significantly related to the treatment group, and there is no evidence of the differential time effect with the treatment. An inter-group analysis yielded no statistically significant results regarding the effectiveness of the treatments received by the patients. This could be because of the small sample size or because „„Sham‟‟ APS is not a useful intervention. Conclusion: The results from this study revealed that all three treatment groups responded equally in the alleviation of pain. However, the dry-needling treatment group alone (Group One) revealed a much more significant decrease in pain compared to the other two. It can thus be concluded that APS Therapy had no significant beneficial effects on post-needling soreness.

Dissertation submitted to the Department of Chiropractic in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, 2006. / Myofascial pain syndrome (MPS) is defined as the sensory, motor and autonomic symptoms caused by myofascial trigger points (MFTPs), or hyperirritable spots within skeletal muscles that are associated with palpable nodules in a taut band. The fact that MFTPs have been described in the literature for acupuncturists, anaesthesiologists, chronic pain managers, dentists, family practitioners, gynaecologists, neurologists, nurses, orthopaedic surgeons, paediatricians, physical therapists, physiologists, rheumatologists and veterinarians is evidence of the syndrome’s clinical importance. As a result of a large amount of research, a large number of different treatments have been shown to be clinically effective in the treatment of MFTP. These treatments include amongst others: - Ischaemic compression. - Myofascial manipulation. - Spray and stretch. - Ultrasound. - Transcutaneous electrical nerve stimulation. - Dry needling. As can be seen from the above, it is important to be able to treat MPS effectively because it is such a common disorder. According to Schneider an effective treatment is needed for MPS, despite the array of treatments available to a clinician. Han and Harrison agree that more studies are required to determine the efficacy of these treatments. The aim of this study is to evaluate the relative effectiveness of Myofascial Trigger point Manipulation (MFTPM) as compared to Proprioceptive Neuromuscular Facilitative (PNF) stretching in the treatment of active Myofascial Trigger Points (MFTPs) in the trapezius muscle (TP 1 and/or TP 2) in terms of subjective and objective clinical findings. The study required a total of 60 patients, which following acceptance were then randomly divided into two groups of 30, with an equal number of male patients in Group one (MFTPM) and two (PNF), and female patients in Group one and Group two. Each patient had four consultations (three treatments and one follow up visit) in a two week period. Subjective and Objective Data was recorded at each consultation prior to the treatment. Subjective measurements (Numerical Pain Rating Scale and Short Form McGill Pain Questionnaire) were taken prior to the treatment at all four visits. Objective measurements (Cervical Range of Motion Meter and Algometer) were also taken prior to the treatment at all four visits, except for Algometer readings which were taken at the initial consultation and the fourth treatment only. SPSS version 11.5 was used for analysis of data (SPSS Inc, Chicago, Ill, USA). Baseline comparisons were done between treatment groups using Pearson’s chi square tests or Fisher’s exact tests as appropriate for categorical variables, and student’s t-tests for quantitative normally distributed variables. Treatment effect was assessed with repeated measures ANOVA. A significant time by group interaction indicated a significant differential treatment effect. A p value <0.05 designated statistical significance. The direction of the treatment effect was assessed with profile plots. Evaluation of data collected from both groups showed a significant improvement in terms of objective and subjective clinical findings to a value of p=< 0.001. There was no statistical difference between the two groups in terms of objective and subjective clinical findings, although a trend was shown when looking at the objective findings that suggest that MFTPM was more effective than PNF stretching. The sample population was drawn from a very homogenous group of people (i.e. SARS call centre), in order to achieve greatest emphasis on clinical outcomes. This process however limits the clinical applicability of the results and thus will not always be applicable to all patients within the population. It is therefore the researcher’s conclusion that there is no statistical difference between MFTPM and PNF stretching in terms of objective and subjective clinical findings. Both treatment modalities have been shown to be equally effective in the treatment of subacute active TPs in the upper tarpezius. There is a definite trend when looking at the objective data that may support the hypothesis that MFTPM is as effective as, if not more effective than PNF stretching. It is of the opinion of the author that a larger sample size is needed to make it clinically significant.

M.Tech. (Chiropractic) / Myofascial trigger points are very common and can become a painful part of most people’s life at one time or another. According to Travell and Simons (1999), active upper trapezius myofascial trigger points are common in patients presenting with neck pain. Myofascial pain syndrome is a regional muscle disorder that is one of the most common causes of persistent pain in the head, face and neck regions (Rachlin, 2002). The PAIN®GONE pen is a device that produces a high voltage, low frequency pulse for only a brief period of time. The electrical stimulation activates endorphins in the hypothalamus which plays a role in pain relief (Puskas, 2004). The technical system of the device is clinically proven and uses Transcutaneous Electric Nerve Stimulation (TENS), based on the pain gate control theory of Melzack and Wall (1965). The purpose of this study was to determine the efficacy of treating active upper trapezius trigger points with PAIN®GONE therapy combined with cervical spine chiropractic adjustments.This study consisted of two groups, the PAIN®GONE therapy group (Group 1) with fifteen participants and the placebo PAIN®GONE therapy group (Group 2) with fifteen participants. The participants were between the ages of 18 and 40 years of age. Prior to becoming a participant of this study, individuals were assessed according to the inclusion and exclusion criteria, a case history, physical examination, cervical regional examination and upper trapezius muscle palpation to assess for upper trapezius myofascial trigger points. Treatment was applied to the cervical spine by Chiropractic adjustments, and to the upper active trapezius myofascial trigger points via PAIN®GONE therapy or placebo PAIN®GONE therapy, from which the subjective and objective data were based.Each participant was treated six times over a period of three weeks. Prior to the initiation of treatment, each participant was requested to complete a Vernon-Mior Neck Pain and Disability Index questionnaire and Numerical Pain Rating Scale. Algometer readings were obtained for the active upper trapezius myofascial trigger points. The Cervical Range of Motion (CROM) goniometer was used to obtain numerical values for the participant’s active cervical spine ranges of motion in flexion, extension, lateral flexion androtation. Both groups, received treatment to the active upper trapezius trigger points and Chiropractic adjustments to the cervical spine for a total of six treatment sessions. Both subjective and objective data readings were obtained before the 1st, 4th and 7th final consultation...
