Item Knowledge and practices of myofascial pain syndrome of the temporomandibular joint by dentists in the Greater eThekwini region(2018) Van der Colff, Hyla; Pillay, Julian David; Docrat, AadilBACKGROUND: Temporomandibular disorders (TMDs) affect up to fifteen percent of adults. It produces craniofacial pain of musculoskeletal structures within the head and neck. One particular cause of TMDs is said to be myofascial pain syndrome (MFPS), which according to various research papers, if not considered and/or assessed, the general cause of a patient’s pain could be disregarded and incorrect treatment offered. Numerous studies conducted internationally on dental management of temporomandibular joint disorder (TMJD) concluded that there is a significant gap in dentists’ education and training regarding the identification and management of MFPS. Upon reviewing the current literature available in South Africa, very little research existed on dentists’ knowledge and the management strategies that they utilised regarding MFPS in TMJD patients. OBJECTIVES: To determine the dentists’ knowledge regarding MFPS of the temporomandibular joint (TMJ). What assessment and treatment/management strategies they use, and whether they make use of referral networks and if the respondents’ demographics influence their knowledge, utilisation, perception and referral patterns. METHODOLOGY: The researcher developed a research questionnaire, which was validated by both an expert and a pilot study group. This questionnaire was then used as a research tool in this cross-sectional study. General dental practitioners from the Greater eThekwini Region received an invitation to participate. The questionnaire-based survey consisted of five sections: biographical profile of respondents; topic background; perception; knowledge; utilisation and management (including referral patterns) of MFPS. RESULTS: The majority of respondents did receive basic education in MFPS, with 76.9% reporting that they received undergraduate education and 57.7% indicating that they had attended post-graduate courses/talks on MFPS. There was a 100% response from dentists indicating their willingness to attend post-graduate courses/talks on MFPS. The results indicated that the respondents, who felt that their curriculum regarding MFPS was sufficient, were more knowledgeable and more competent in diagnosing and managing MFPS. Overall, the average score for knowledge was 65.17%. Clinical features (78.85%) and the perpetuating and relieving factors (72.11%) scored the highest while causes (58.06%) and differential diagnoses (51.16%) scored the lowest knowledge levels. Respondents mostly made use of allopathic medical fields, and not of alternative medical fields, however a high number of respondents (73.1%) indicated that they would consider chiropractic co–management of patients with MFPS. CONCLUSION: This study adds new information in the South African context regarding dentists’ understanding of the myofascial component of TMDs. It also provides the dental profession with information about the knowledge and practices related to MFPS as well as information regarding the strengths and weaknesses on its educational component. It is recommended that dentists receive additional training on differential diagnoses and causes. It is also recommended that the chiropractic profession take this opportunity to offer courses/talks on MFPS and join forces with the dentistry profession on how they can assist in managing patients with MFPS.Item The relative effectiveness of myofascial trigger point manipulation as compared to proprioceptive neuromuscular facilitative stretching in the treatment of active myofascial trigger points: a pilot clinical investigation(2006) Berry, Jason; Mac Dougall, TarrynMyofascial 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.
