Dissertation submitted in partial compliance with the requirements for the Masters Degree in Technology: Chiropractic, Durban University of Technology, 2011. / Background: Myofascial pain is a disorder, characterized by the presence of trigger points (MTrP). It is recognised by unique features which include a tender point in a taut band of muscle, a local twitch response (LTR), a characteristic referred pain pattern, and the reproduction of the patient’s usual pain upon examination. A debate exists as to the precise diagnostic criteria used in identifying trigger points. This has hampered the standardized assessment and treatment of Myofascial Pain Syndrome and has led to contradictory findings being reported by various authors due to the lack of a reliable diagnostic tool. Objectives: The first objective was to determine the inter-examiner reliability of palpation of MTrPs in the trapezius and gluteus medius muscles. The second objective was to determine whether training and standardization in palpation techniques would improve inter-examiner reliability of palpation of MTrPs. Methods: This study was designed as a quantitative pre and post intervention interexaminer reliability study. Three examiners (one qualified Chiropractor, one senior chiropractic intern from the CDC and the researcher) were used to examine sixty patients (thirty symptomatic and thirty asymptomatic) for MTrPs. This study was conducted in two phases. During the myofascial examination of patients examiners were required to determine whether a MTrP was present or absent, differentiate whether the MTrP was active or latent and determine the presence or absence of the five characteristics of MTrP (tender point in a taut band of muscle, a local twitch response (LTR), a pain characteristic referred pain pattern, the reproduction of the patient’s usual pain and a jump sign) however, in phase one the researchers were blinded to the characteristics being investigated. Subsequent to phase one, examiners had to attend two, one hour discussion sessions to reduce individual variation in the application of palpation techniques. Results: Inter-examiner reliability was assessed using Fleiss Kappa statistic, percentage agreement and confidence intervals. The results show that three examiners are able to attain acceptable agreement in the palpation of MTrPs, since the features (described above) were shown to improve considerably in phase two after the training session in which standardization of techniques was emphasized. Conclusion: This study provides preliminary evidence that MTrP palpation is reliable and therefore, useful diagnostic tool in the identification of MTrPs and the diagnosis of Myofascial Pain Syndrome.

<p>Bruxism is an oral parafunctional habit involving clenching and grinding of the teeth that occurs mainly unconsciously, diurnally and nocturnally. It is considered an important contributory factor in the aetiology of myofascial pain (MFP) and temporomandibular disorders (TMD). The aetiology of bruxism is considered to be multifactorial, involving physiological and psychological factors. The aim of this study was to examine the relationship between the subthreshold symptoms (subtle, prodromal, atypical and subclinical symptoms of which the severity precludes diagnosis as a disorder) of anxiety and bruxism in a sample of subjects using a spectrum model.</p>

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...

M. Tech. / Background: No substantiated theory exists by which chiropractic adjustments are known to correct myofascial trigger points (MTrPs). Myofascial trigger points are theorized to be either a primary muscle dysfunction or a secondary manifestation to central/ peripheral neurological mechanisms. Chiropractic adjustments are theorized to exert their therapeutic influence either primarily through biomechanical effects and/ or via neurophysiological mechanisms. Objective: The objective of this study was to investigate the effects of chiropractic adjustments on chronic, active rhomboid MTrPs, by comparing the clinical effects attained with rhomboid attachment-segment (C7-T5) relative to rhomboid innervation-segment (C4 and/ or C5) chiropractic adjustments. Setting: University of Johannesburg Chiropractic Day Clinic in Johannesburg, Gauteng. Participants: Thirty female subjects selected from the general population (from 18 to 40 years) were randomly divided into two different treatment groups of 15 each. Methods: The subjective information required the completion of the Subjective Pain and Discomfort Questionnaire, including the Numerical Pain Rating Scale (NPRS). The objective measures collected were pressure-pain threshold (PPT) and range of motion measurements using the algometer and digital inclinometer, respectively. Additionally, the change in the number of active MTrPs over the treatment period was recorded. All measurements were recorded at the first, third and fifth consultations, over a 3 to 4 week period. The data gathered were then statistically analyzed with the use of a 95% confidence interval. The nonparametric Friedman and Wilcoxon Signed Rank tests were used for the intragroup comparisons, and the Mann Whitney- U test was used for the intergroup comparisons. Interventions: Treatment group 1 received upper-thoracic/ attachment- segment chiropractic adjustments, and treatment group 2 received mid-cervical/ innervation-segment chiropractic adjustments. The research project was carried out so that both groups received 5 treatment sessions over 3 to 4 weeks. Results: There were no statistically significant results obtained for intergroup comparisons. Attachment-segment chiropractic adjustments revealed statistically significant changes in NPRS values (p=0.000), PPT values (p=0.000), cervical spine right lateral flexion range (p=0.004), thoracic spine extension (p=0.005) and left rotation range (p=0.003) over time. Innervationsegment chiropractic adjustments revealed statistically significant changes in NPRS values v ii (p=0.001), cervical spine right rotation (p=0.003), thoracic spine flexion (p=0.001) right lateral flexion (p=0.001) and left rotation (p=0.005) over time. Conclusions: This study does not suggest that attachment-segment or innervation-segment chiropractic adjustments possess greater clinical efficacy relative to one another in terms of improving the clinical picture associated with chronic, active rhomboid MTrP activity. In a further study, a larger sample size will be necessary to identify subtle changes in measurement parameters.

M. Tech. / OBJECTIVE: The aim of the study was to explore whether dry needle therapy delivered to latent myofascial trigger points of the biceps brachii muscle had an immediate effect on muscle activity and strength . DESIGN: One hundred participants with latent myofascial trigger points of the biceps brachii muscle and who were suitable for the study were drawn from the community. They were al located in to either a controlor treatment group so that each group contained fifty participants . The control and treatment group were divided in such a way to ensure that the two groups were comparable with one another un terms of age and gender. The International Physical Activity Questionnaire was completed by each participant to ensure that the two groups were also comparable with one another in terms of the total amount of physical activity performed per week. The results of this study were statistically analysed by STATKON at the University of Johannesburg.

M.Tech. / This study was conducted to investigate the efficacy of Chiropractic cervicothoracic spinal adjustment therapy in the treatment of active Trapezius myofascial trigger point dysfunction. Thirty participants were recruited and placed into one of two groups. Participants were between the ages of 18 and 30 years and selected based on the inclusion criteria being met. Participants had to present with active upper Trapezius trigger points and a restriction of the cervicothoracic junction. The experimental group received a Chiropractic adjustment to the cervicothoracic junction and the control group received detuned ultrasound as their respective treatments. The participants were treated six times over a 3-week period and measurements were taken on the first, fourth and seventh visits. A case history, physical examination and cervical regional examination were conducted at the first visit. Objective measurements included pressure algometry readings of Trapezius trigger points 1 and 2 and cervical spine goniometry readings. Subjective measurements included the Vernon Mior Pain Disability Index and the Numerical Pain Rating Scale. The results were interpreted by Statcon at the University of Johannesburg. The data was analysed using the Mann Whitney test and the Friedman test. According to the tests, the experimental group improved significantly in both the objective and subjective measurements over the seven visits. The control group showed an increase in the objective measurements and a decrease in the subjective measurements over the seven visits. This was found to be statistically insignificant. This study concluded that a Chiropractic adjustment to the cervicothoracic junction is effective in the treatment of upper Trapezius trigger points

M.Tech. / The term „myofascial‟ is derived from the word „myo‟ meaning muscle and „fascia‟ meaning connective tissue. Myofascial pain syndrome is a regional pain syndrome characterized by the presence of myofascial trigger points (Mense and Simons, 2001). The most crucial component of myofascial pain is muscle shortening from contracture (or „spasm‟). In fact, myofascial pain does not exist without muscle shortening. Prolonged shortening not only causes pain in the muscle but also physically pulls on tendons, thereby straining them and distressing the bone and joints they insert into and act upon (Gunn, 2002). Trigger points are most often discussed in the setting of myofascial pain syndromes, in which widespread or regional muscular pain is associated with hyperalgesia, psychological disturbance and significant restriction of daily activities (Huguenin, 2004).

M.Tech. / Problem Statement: Myofascial Pain Syndrome (MPS) is a painful and prevalent muscular condition that is characterized by the development of myofascial trigger points (TrP’s). These are locally tender when active and are able to refer pain through specific patterns to other areas of the body distal from the trigger point (Manga, 2008). Myofascial trigger points are a frequently overlooked and misunderstood source of the distressingly ever-present musculoskeletal aches and pains of mankind and many authors have found that the trapezius muscle is most often the muscle that has frequent myofascial trigger points (Travell and Simons, 1999). Much debate and discussion has arisen on the merits of the fanning dry needling technique compared to that of the static dry needling technique, but research evidence is very limited. Some practitioners prefer the static technique over the fanning technique as it reduces the presence and amount of post-needling soreness, as well as reduces the possibility of penetrating a blood vessel resulting in hemorrhaging. Other practitioners prefer the fanning technique as it increases the chances of locating the loci of the TrP, as well as increasing the chances of eliciting a local twitch response and possibly making this method more effective in deactivating a TrP than the static technique. Aim of Study: The aim of this study was to compare the effects of static myofascial dry needling to the effects of fanning myofascial dry needling of an active trigger point (TrP1) in the upper trapezius muscle in order to determine which of the two treatments is more effective with regards to decreasing neck pain and disability as well as increasing pressure pain threshold in patients with neck pain due to Trapezius Myofascial Pain Syndrome. Method: Forty participants underwent a general screening to determine whether they had active myofascial trigger points in the upper fibers of the trapezius muscle.
