Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2018. / BACKGROUND: 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. / M

Using this methodology, it is possible to evaluate the physiology of thermical maintenance through its skin surface representation. The aim of this work is to evaluate the thermography as the identification method of myofascial trigger points, been chosen the trapezius muscle as study focus since it is one of most affected body regions concerning myofascial syndrome. This syndrome is highly prevalent and historically sub-diagnosticated as it requires expert professionals to establish its diagnostic, through physical examination. The articipants of this study were gathered as a sample of thirty persons, fifteen men and fifteen woman, ages between twenty three and seventy years (32,5 years in average). The algometry by pressure, highly validated method on previous works, has been used as part of physical examination to confirm the thermography events. The equipment used to collect the thermograms was an infrared camera with digital image processing, with thermical sensitivity for spectral ranges from 7 to 12 micrometers, appropriate for medical diagnostic utilization; the error index for measurement on this equipment is either 2% or 2oC. It has been used a dynamometer, clock type, for the algometry, commercially available for clinical use, which makes possible to evaluate the applied pressure to the focal point. The trigger point identification was based in a pain diagram filled by the own subject using previously validated parameters. The imaging evaluation was done using a descriptive analysis, having been taking in consideration the thermographic event corresponding to the trigger point, the hot spot or a discoid shaped surface, with one or more degrees Celsius hotter if compared to the neighbor reference point. Algometry was used in this work as reference method It was applied descriptive statistics for evaluate sensibility and specificity in trapezius Myofascial Syndrome diagnoses. A totality of 250 trigger points had been founded: 198 (79.20%) identified by algometry and thermography; 41 points (16.40%) by thermography only; 11(4.40%) identified by algometry only. It was concluded that the thermograpy is an appropriated method for Myofascial Syndrome diagnostic on trapezius muscle. / A termografia, sistema com capacidade de captar a emissividade de luz infravermelha de qualquer superfície reflexiva, faz parte do arsenal atual de instrumentação em biomecânica. Com esta metodologia pode-se avaliar a fisiologia da manutenção térmica através de sua representação cutânea. O presente trabalho teve por objetivo avaliar a termografia comptadorizada na identificação de trigger points miofasciais, tendo sido escolhido o músculo trapézio como foco de estudo, por esta ser uma das regiões corporais mais acometidas pela Síndrome Miofascial. Esta síndrome é altamente prevalente na população adulta ativa e, historicamente, sub-diagnosticada por requerer profissional especializado e treinado para estabelecer seu diagnóstico, que é através de exame físico. Os participantes deste estudo compunham uma amostra de trinta sujeitos, quinze homens e 15 mulheres, com idade entre 23 e 70 anos (média de 32,5 anos). A algometria de pressão, método validado amplamente em estudos prévios, foi utilizada como parte do exame físico para confirmação ou não dos eventos da termografia. O equipamento utilizado para coleta dos termogramas foi uma câmara de infravermelho com processamento digital de imagens, com sensibilidade térmica em faixa espectral de 7 a 12 micrômetros, adequada à sua aplicação no diagnóstico médico; o índice de incerteza de medição deste equipamento é de 2% ou 2ºC. Para a algometria, utilizou-se um dinamômetro tipo relógio, disponível comercialmente para uso clínico, que permitiu avaliar a pressão aplicada aos pontos de interesse. A identificação dos trigger points foi baseada em diagrama de dor preenchido pelo próprio sujeito e utilizando-se parâmetros previamente validados em publicações cientificas. A avaliação das imagens foi realizada através de análise descritiva, valorizando-se o evento termográfico correspondente ao trigger point, que é um hot spot ou, área em formato discóide, com hipertermia de um ou mais graus Celsius em relação a um ponto de referência circunvizinho. A algometria foi usada como método de referência neste estudo. Utilizou-se análise estatística descritiva dos dados para avaliar a sensibilidade e a especificidade da termografia no diagnóstico de Síndrome Miofascial de músculo trapézio. Foram identificados um total de 250 trigger points; destes, 198 (79,20%) foram identificados pela algometria e termografia simultaneamente; 41 pontos (16,40%) identificados apenas pela termografia e 11 pontos (4,40%) identificados apenas pela algometria. Concluiu-se que a termografia é eficaz na identificação de trigger points miofasciais de músculo trapézio.

A síndrome da dor miofascial crônica é a causa mais frequente das dores musculoesqueléticas com prevalência mundial que varia entre 13,7% e 47% da população, destes, em torno de 17% apresentam dores na região do retropé medial. O músculo abdutor do hálux que se localiza na região medial do pé representa grande importância para as síndromes dolorosas plantares, seu estudo será importante para compreender melhor a fisiopatologia da dor miofascial que ainda permanece desconhecida. Objetivos: Descrição dos pontos de penetração dos ramos do nervo plantar medial no ventre do músculo abdutor do hálux através da dissecção anatômica e a sua inter-relação com os sintomas clínicos de dor plantar nos pacientes ortopédicos. Método: O estudo foi realizado em dois grupos com a amostra calculada pelo projeto piloto realizado anteriormente. No grupo de dissecção anatômica (GDA) foram dissecados 30 pés para a avaliação do número de pontos de entrada dos ramos nervosos no músculo associado ao grupo dos pacientes ortopédicos (GPO) onde 30 pés com sintomas de dor no retropé medial foram submetidos à avaliação da sensibilidade dolorosa com o dolorímetro digital de pressão. Ambos os grupos utilizaram o referencial dos quadrantes no músculo abdutor do hálux. O GDA foi submetido a análise de equações de estimação generalizadas com distribuição Poisson e função de log logaritmo seguida de comparações múltiplas de Bonferroni assim como no GPO mas para a distribuição normal e função de ligação identidade, os dados foram expressos em média ± desvio padrão. O nível de significância foi ajustado para 5% (p < 0,05). Resultados: Neste estudo o GDA apresentou uma diferença estatisticamente significante de pontos de entrada dos ramos do nervo plantar medial no ventre muscular do abdutor do hálux no primeiro quadrante (póstero-lateral, Q1, p < 0,05) em relação aos demais quadrantes, assim como no GPO onde Q1 também apresentou uma maior sensibilidade dolorosa quando comparado aos demais quadrantes (p < 0,05). Foi registrado a partir das dissecções uma inédita fixação no osso navicular do músculo abdutor do hálux. Conclusão: Nossos resultados sugerem que existe uma possível relação entre o maior número de entrada dos ramos do nervo plantar medial no ventre do músculo abdutor do hálux e a maior sensibilidade dolorosa no retropé medial, ou seja, os problemas musculares podem desencadear sintomas clínicos dolorosos a partir da compressão nervosa na região. Os dados vão cooperar para a melhor compreensão das síndromes miofasciais dos pés que auxiliarão para o desenvolvimento de futuros tratamentos / Chronic myofascial pain syndrome is the most frequent cause of musculoskeletal pain, with a worldwide prevalence ranging from 13.7% to 47% of the population, which 17% have pain in the retromedial area. The abductor hallucis muscle is located in the medial region of the foot represent high importance for plantar painful syndromes and your study will be important to better understand the pathophysiology of myofascial pain that remains unknown. Objectives: Description through anatomical dissection of the penetration points of the medial plantar nerve branches in the abductor hallucis muscle layer and their interrelationship with the clinical symptoms of plantar pain in orthopedic patients. Methods: The study was carried out in two groups, the sample size was calculated by the previous pilot study. In the anatomical dissection group (ADG), 30 feet were dissected for the evaluation of the number of entry points of the nerve branches in the muscle belly associated with the orthopedic patients group (OPG) where 30 feet with pain symptoms were submitted to the evaluation of pain sensitivity with digital pressure gauge, both groups used the quadrants referential in the abductor hallucis muscle for the evaluation. The ADG were submitted to the analysis of generalized equation of estimation with Poisson distribuition and log logarithnm and was followed by Bonferroni multiple comparisons, for OPG the same analysis but for normal distribution and identity link function, the datas were expressed as mean ± standard deviation. The level of significance was adjusted to 5% (p < 0.05) for all tests. Results: In this study, the ADG presented a statistically significant difference of medial plantar nerve branches entry points in the first quadrant (posterolateral, Q1) in the abductor halluccis muscle (p < 0.05) in relation to the others, as well as in the OPG, where the first quadrant (Q1) also presented a greater pain sensitivity when compared to the other quadrants (p < 0.05). It was recorded an unprecedented navicular bone fixation from abductor hallucis muscle. Conclusion: Our results suggests that there are a possible relationship between the greater number of entry of the medial plantar nerve branches in the abductor hallucis muscle and the higher pain sensation in the retromedial plantar area and the muscle can trigger an nervous compression to develop painful symptoms. These datas will cooperate to better understand myofascial pain syndromes that will help to develop new treatments

Orientador: Guilherme Antonio Moreira de Barros / Resumo: A Síndrome Dolorosa Miofascial (SDM) é considerada um importante problema de saúde pública, podendo, muitas vezes, ser incapacitante e de difícil tratamento. Considerando que, atualmente, o tratamento da SDM é pouco eficaz para o controle da dor, verificamos a necessidade do estudo de novas técnicas e da comparação com as técnicas já existentes. O presente estudo teve como objetivo comparar técnicas de eletroestimulação intramuscular com a técnica de agulhamento seco para o tratamento dessa enfermidade musculoesquelética. Foram estudados 90 pacientes divididos em três grupos. O primeiro grupo foi tratado com agulhamento seco em pontos de gatilhos (PGs), o segundo grupo com eletroestimulação intramuscular de PGs e o terceiro grupo foi tratado com eletroestimulação de pontos motores (PMs) pertencentes ao músculo acometido e/ou o nervo responsável pela inervação desse músculo. O músculo utilizado foi a porção superior do trapézio que é inervado pelo nervo acessório espinal. Foram realizadas sete sessões de tratamento em cada grupo e todos foram avaliados antes e após o término do mesmo. Não houve diferença estatisticamente significativa nos escores de dor da Escala Verbal Numérica (EVN) entre os grupos estudados, apesar de todas as intervenções terem se mostrado eficazes para o tratamento da dor miofascial do músculo trapézio. / Abstract: Myofascial Pain Syndrome (SDM) is considered an important public health problem and can often be disabling and difficult to treat. Considering that, currently, the treatment of SDM is not very effective for pain control, we verified the need to study new techniques and to compare them with existing techniques. The present study aimed to compare intramuscular electrostimulation techniques with the dry needling technique for the treatment of this musculoskeletal disease. Ninety patients were studied, divided into three groups. The first group was treated with dry needles at trigger points (PGs), the second group with intramuscular electrostimulation of PGs and the third group was treated with electrostimulation of motor points (PMs) belonging to the affected muscle and / or the nerve responsible for innervation of that muscle. The muscle used was the upper portion of the trapezius, which is innervated by the spinal accessory nerve. Seven treatment sessions were carried out in each group and all were evaluated before and after the end of the same. There was no statistically significant difference in pain scores on the Numerical Verbal Scale (EVN) between the groups studied, although all interventions have been shown to be effective for the treatment of trapezius muscle myofascial pain. / Doutor

INTRODUÇÃO: O tratamento com ondas de choque (TOC) é utilizado para tratar numerosas afecções musculoesqueléticas, incluindo-se as pseudartroses e as tendinopatias. Há poucos estudos bem estruturados sobre a eficácia do TOC no tratamento da síndrome dolorosa miofascial (SDM) e não há ensaio clínico aleatorizado sobre sua utilização no tratamento das SDMs das regiões lombar e glútea. OBJETIVOS: Avaliar a eficácia do TOC no tratamento das SDMs das regiões lombar e glútea. CASUÍSTICA E MÉTODOS: Foi realizado estudo prospectivo, controlado, com amostra aleatória e duplamente encoberto sobre o tratamento de doentes com dor moderada a intensa decorrente de SDM nas regiões lombar e glútea com duração superior a seis meses, submetidos previamente a tratamento padronizado com antidepressivo, analgésico, terapia física e orientações fisioterápicas durante seis semanas. Foram elegíveis 46 doentes que apresentavam dor com intensidade >= 4 de acordo com a EVA dentre os 121 convocados. Durante seis semanas os doentes elegíveis foram submetidos a tratamento farmacológico e fisioterápico padronizado. Sete doentes usufruíram melhora clínica importante e oito abandonaram o estudo, restando 31 doentes que participaram efetivamente do estudo. Após a randomização, 14 doentes foram submetidos a TOC com cabeçote ativo e 17 a TOC com cabeçote placebo. Foram avaliados os aspectos demográficos, a apresentação clínica, a incapacidade funcional, a intensidade e as características da dor até um ano após a realização dos procedimentos destes 31 doentes. As avaliações foram realizadas com uso da Escala Visual Analógica (EVA), Questionário de Incapacidade de Roland-Morris (RDQ), Índice de Incapacidade de Oswestry (ODI), Versão Reduzida do Questionário de Dor McGill (SF-MPQ) e Inventário Diagnóstico da Dor Neuropática 4 (DN4). RESULTADOS: Não houve diferenças estatisticamente significativas entre os grupos quanto às características sociodemográficas dos doentes. Entretanto, a duração das queixas de dor dos doentes do grupo TOC ativo foi significativamente superior (p < 0,05) a dos do grupo TOC placebo. Em relação aos doentes tratados com TOC placebo, os doentes tratados com TOC ativo usufruíram redução estatisticamente significativa da dor de acordo com a EVA na interação grupo versus tempo a partir do momento \"três meses\"; a melhora manteve-se estatisticamente significativa durante um ano (p < 0,001), achado que sugere que o efeito analgésico instala-se em longo prazo e mantém-se prolongadamente. Não ocorreu modificação estatisticamente significativa na interação grupo versus tempo nas pontuações dos questionários RDQ, ODI e SF-MPQ ao longo do tempo nos doentes de ambos grupos. No momento \"12 meses\" ocorreu redução superior a 50% da incapacidade funcional da dor lombar avaliada de acordo com o RDQ em 70,0% dos doentes do grupo TOC ativo e em apenas 14,3% dos doentes tratados com TOC placebo; diferença percentual estatisticamente significativa (p < 0,05). Ocorreu também redução superior a 50% das pontuações do ODI na avaliação realizada no momento \"12 meses\" em 70,0% dos doentes incluídos no grupo TOC ativo e em apenas 14,3% dos doentes do grupo TOC placebo, diferença percentual estatisticamente significativa (p < 0,05). CONCLUSÕES: O tratamento com o TOC ativo dos doentes com SDM nas regiões lombar e glútea proporcionou melhora significativa da dor a partir do momento \"três meses\" até, pelo menos, o momento \"12 meses\" de acompanhamento, achado que sugere que seu efeito analgésico instala-se tardiamente. Adicionalmente, proporcionou melhora da funcionalidade de acordo com o RDQ e ODI na avaliação realizada no momento \"12 meses\" / INTRODUCTION: Extracorporeal shockwave therapy (ESWT) has been used successfully in different musculoskeletal conditions, including pseudarthrosis and tendinopathies. However, there are very few well-structured studies on the efficacy of ESWT in the treatment of myofascial pain syndromes (MPSs) and no randomized clinical trial about the ESWT in the treatment of lumbar and gluteal myofascial pain. OBJECTIVES: To assess the efficacy of ESWT in the treatment of lumbar and gluteal MPSs. MATERIAL AND METHODS: The study was prospective, randomized, double-blind and placebo-controlled. From 121 patients with moderate or severe pain due to MPS in the lumbar and gluteal regions lasting more than six months were enrolled; a total of 46 patients with pain intensity >= 4 according to the VAS were considered eligible. The elected patients were treated with antidepressant, analgesic and physical therapy as a standard protocol during six weeks. Seven patients had significant clinical improvement with the pharmacological and physical therapies and eight dropped out the study. The remainder 31 patients were randomized and 14 underwent active ESWT and 17 underwent placebo ESWT. The demographic aspects, clinical presentations, functional disabilities, severity and characteristics of pain were evaluated previously to the inclusion in the study until the end of the first year after the treatment with active or placebo ESWT. The evaluations were based on the Visual Analogue Scale (VAS), Roland- Morris Disability Questionnaire (RDQ), Oswestry Disability Index (ODI), Short- Form of the McGill Pain Questionnaire (SF-MPQ), and the Neuropathic Pain Diagnostic Questionnaire 4 (DN4). RESULTS: There were no statistical differences between the groups regarding the baseline characteristics of the patients. However, the duration of pain of the patients treated with active ESWT was significantly higher (p < 0,05) than those treated with placebo ESWT. There was no statistically significant variation over time in the RDQ, ODI and SF-MPQ scores between the patients from each group. Patients treated with active ESWT presented a significant reduction of pain severity according to the VAS from the third until the 12nd month of follow-up (p < 0,001), finding indicative that the analgesic effect of the ESWT starts late but remains over time. At the 12nd month of follow-up, 70,0% of the patients treated with active ESWT and just 14.3% of the patients from de placebo ESWT group had more than 50% improvement of the functional disability of the low back pain according to the RDQ, statistically significant difference (p < 0,05). There was also a reduction of more than 50% of ODI scores in the 12th month of follow-up in 70.0% of the patients treated with active ESWT and in only 14.3% of the patients treated with placebo ESWT (p < 0,05). CONCLUSIONS: The active ESWT provided a significant and lasting reduction in pain intensity from the third until the 12th month of follow-up, finding that suggests that its analgesic effect settles late and has long duration. Additionally, it provided improvement of the functionality according to the RDQ and ODI at the 12th month of follow-up

Abstract Aim: The aim of this study was to investigate if treatment with “dry needling” in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment? Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment. The intervention group was treated twice, with a week in between, with “dry needling” in MTrPs. The control group was also treated on two occasions but was instead given a superficial needle in the infraspinatus muscle. All subjects were treated by the same physiotherapist. Pain was evaluated on the VAS when subjects performed active shoulder flexion before and after treatment. Provocative tests for shoulder impingement (Neer sign, Hawkins-Kennedy test and Jobe test) as well as range of motion tests were performed before, after and three weeks after treatment. The frequencies of positive/negative provocative tests were presented. Shoulder function was evaluated with the QuickDASH questionnaire. Significance level p≤0.05 was used in the study and a tendency was identified between 0.05 ≤ p &lt; 0.1. Results: There was a tendency (p=0.086) with decreased pain (VAS) in the intervention group after the treatment. Among the impingement tests only significant improved results was observed for Neer sign test three weeks after the treatment (p=0.025) No significant difference could be seen on the active shoulder mobility between before and after the treatment. The perceived function in the intervention group, measured with the Quick DASH questionnaire, showed a tendency (p=0.086) towards a better function. Conclusions: The study showed a tendency towards that”dry needling”  in MTrPs may affect impingement symptoms such as pain and function. The provocative tests for shoulder impingement, Neer sign, showed a significant decrease in pain after treatment. More studies with larger population is needed to make a statement about the effect of “dry needling” in MTrPs as a treatment for shoulder impingement symptoms. / Sammanfattning Syfte och frågeställningar: Syftet med studien var att undersöka om behandling med ”dry needling” (intramuskulär nålstimulering) i myofasciella triggerpunkter (MTrPs) i rotatorcuffmuskulaturen kan påverka impingementsymptom såsom smärta vid provokationstester, axelledsrörlighet och funktion. Frågeställningarna var: Förändras smärtskattning på visuell analog skala(VAS) vid aktiv axelflexion efter jämfört med före behandling? Förändras de positiva provokationstesterna för impingement efter jämfört med före behandling? Förändras den aktiva axelledsrörligheten efter jämfört med före behandling? Förändras den självskattade funktionen efter jämfört med före behandling? Metod: Studien var en prospektiv randomiserad interventionsstudie, 19 forskningspersoner (fp) med impingementsymptom, (medelålder 58 ± 18 år, besvärsdurationens medeltid 3.9 ± 1.6 mån), randomiserades till två grupper. Grupperna undersöktes före, direkt efter och tre veckor efter avslutad behandling. Interventionsgruppen behandlades vid två tillfällen, med en veckas mellanrum, med ”dry needling” i MTrPs medan kontrollgruppen vid två tillfällen istället fick en ytlig akupunkturnål i m infraspinatus. Behandlingen av alla fp utfördes av en och samma fysioterapeut. Smärta utvärderades med (VAS) vid aktiv axelflexion direkt före och efter behandling. Provokationstester (Neer sign, Hawkins-Kennedy test och Jobe test) samt rörlighetsmätning utfördes före, efter och tre veckor efter avslutad behandling. Frekvensen positiva/negativa provokationstesttest summerades. Funktionen utvärderades med frågeformuläret QuickDASH. Signifikansnivå p&lt; 0.05 används i studien och en tendens identifierades mellan 0.05 ≤ p &lt; 0.1. Resultat: Det fanns en tendens (p=0.086) till minskad smärta (VAS) i interventionsgruppen efter jämfört med före behandling. Bland impingementtesterna sågs enbart ett signifikant förbättrat resultat för Neers sign tre veckor efter avslutad behandling jämfört med före behandling (p=0.025). Ingen signifikant skillnad kunde ses gällande rörligheten före och efter behandling. Den upplevda funktionsförmågan mätt med frågeformuläret QuickDASH visade en tendens (p=0.086) mot bättre funktion i interventionsgruppen. Slutsats: Studien har visat tendenser på att ”dry needling” i MTrPs kan påverka impingementsymptom såsom minskad smärta och bättre självskattad funktion efter behandling jämfört med före. Impingementtestet Neer sign visade en signifikant minskad smärta efter behandling. Fler studier med större grupper, större ålderspann och längre behandlingstid behövs för att kunna uttala sig om effekten av ”dry needling” i MTrPs som behandlingsmetod vid impingementsymptom i axeln. / <p>Fristående kurs i Idrottsvetenskap inriktning idrottsmedicin 2013-2015</p>

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, 2014. / Background: Myofascial Pain and Dysfunction (MPD) is a diagnosis commonly encountered by practitioners, hence, there are several treatment approaches employed by various practicing physicians. Practitioners are required to perform evidence-based protocols on patients; however, such intervention becomes increasingly difficult with the increasing volume of evidence available with regards to treatment of MPD. A systematic review provides a well-structured, critical analysis of the available protocols, and as such, provides practitioners with an evidence-based summary of the available modalities and the effectiveness of these modalities. Thus, the aim of the study was to systematically review and evaluate the literature to determine the effects of various non-invasive modalities on MPD. Objectives: Studies investigating various non-invasive modalities were identified, evaluated against the inclusion criteria and then reviewed against PEDro criteria to present current available evidence regarding their effectiveness as a source of treatment for MPD. Methods: A literature search was conducted, based on key terms including: active and latent myofascial trigger points, manual therapy, manipulation, acupressure, massage, muscle stretching, ultrasound, transcutaneous electric nerve stimulation, electric stimulation therapy, magnetic field therapy, and exercise therapy. Databases searched were: PubMed, EBSCOhost, Medline, CINAL, Proquest, Health Source, Sport Discus, Science Direct, Springer Link, Google Scholar and Summons. The articles were screened according to inclusion and exclusion criteria, after which a secondary hand and reference searches were performed. Thereafter, the articles were reviewed by four independent reviewers and the researcher. The PEDro Scale was used to determine methodological rigor of the included studies. The results were then analysed and ranked. Results: Following the screening process during data collection for this study, a total of 25 studies were identified and included. The review and ranking of these studies revealed a moderate level of evidence present for the effectiveness of Topical Agents. A limited level of evidence was noted for TENS, Ischemic Compression, Ultrasound, Laser and Other Modalities. Approximately 25% of the reviewed studies involved combination therapies; hence their outcomes cannot be applied to the effectiveness of individual modalities. Conclusion: Upon comparison of the quality of evidence available for the various types of modalities present for the treatment of MPD, it was noted that Topical Agents were supported by a stronger level of evidence than TENS, Ischeamic Compression, Ultrasound, Laser and Other Modalities. However, due to a lack of strong overall evidence for any of these modalities it has been concluded that more research is required to establish which modality is in fact the most effective.
