Manual therapy prevents onset of nociceptor activity, sensorimotor dysfunction, and neural fibrosis induced by a volitional repetitive task.

Painful and disabling musculoskeletal disorders remain prevalent. In rats trained to perform repetitive tasks leading to signs and dysfunction similar to those in humans, we tested whether manual therapy would prevent the development of the pathologies and symptoms. We collected behavioral, electrophysiological, and histological data from control rats, rats that trained for 5 weeks before performing a high-repetition high-force (HRHF) task for 3 weeks untreated, and trained rats that performed the task for 3 weeks while being treated 3x/week using modeled manual therapy (MMT) to the forearm (HRHF + MMT). The MMT included bilateral mobilization, skin rolling, and long axis stretching of the entire upper limb. High-repetition high-force rats showed decreased performance of the operant HRHF task and increased discomfort-related behaviors, starting after training. HRHF + MMT rats showed improved task performance and decreased discomfort-related behaviors compared with untreated HRHF rats. Subsets of rats were assayed for presence or absence of ongoing activity in C neurons and slow Aδ neurons in their median nerves. Neurons from HRHF rats had a heightened proportion of ongoing activity and altered conduction velocities compared with control and MMT-treated rats. Median nerve branches in HRHF rats contained increased numbers of CD68 macrophages and degraded myelin basic protein, and showed increased extraneural collagen deposition, compared with the other groups. We conclude that the performance of the task for 3 weeks leads to increased ongoing activity in nociceptors, in parallel with behavioral and histological signs of neuritis and nerve injury, and that these pathophysiologies are largely prevented by MMT.

Creatine Supplementation Supports the Rehabilitation of Adolescent Fin Swimmers in Tendon Overuse Injury Cases.

Our purpose was to investigate the effect of creatine (Cr) supplementation on regeneration periods in tendon overuse injury rehabilitation of adolescent fin swimmers. The participants of this study were injured adolescent competitive fin swimmers (n = 18). The subjects were randomly assigned the creatine (CR) or placebo (PL) groups with a double-blind research design. The subjects were given Cr supplementation or received the placebo as part of the conservative treatment of the tendinopathy. We measured the segmental lean mass (SLM;kg), the ankle plantar flexion peak torque (PFT;N·m), the pain intensity (NRS;values), prior to immobilization, after immobilization (R2) and after the 2nd (R4) and 4th (R6) weeks of the rehabilitation period of the injured limb. The creatine kinase (CK; U/L) enzyme levels were measured before immobilization, and then every 24 hours for four days. There was a significant decrease in SLM (CR by 5.6% vs. PL by 8.9%; p < 0.03) after two weeks of immobilization in both groups (p < 0.001). After four weeks rehabilitation the SLM significantly increased in both groups (CR by 5.5% vs. PL by 3.8%; p < 0.01). The percent changes in PFT after supplementation in R4 (p < 0.001) and R6 (p < 0.03) were significantly different between groups. There was a significant percent increase measured in the CR group (R4 by 10.4%; p < 0.001; R6 by 16.8%; p < 0.001), whereas significant, but lower growth found in the PL group also took place (R4 by 7.1%; p < 0.001; R6 by 14.7%; p < 0.001) after four weeks of rehabilitation. Significantly faster decrease were found in NRS of CR versus PL group during treatment (p < 0.02). We detected significantly lower CK levels increase at the CR group compared to the PL group. The results of this study indicate that Cr supplementation combined with therapeutic strategy effectively supports the rehabilitation of tendon overuse injury of adolescent fin swimmers.

Freeing the foot: integrating the foot core system into rehabilitation for lower extremity injuries.

The intrinsic muscles of the foot play a critical role in the regulation of absorption and propulsion during dynamic activities. Dysfunction of these may lead to an increased demand on the remaining components within the foot core system to maintain dynamic foot control, leading to a more rapid breakdown of these contributors and those proximal to the foot. Training the intrinsic foot muscles through a systematic progression of isolation via the short foot exercise offers the opportunity to reincorporate their contribution into the foot core system. This article discusses the function of the intrinsic foot muscles, their contributions to dynamic foot control, and a progressive training paradigm.

Effects of a therapeutic laser and passive stretching program for treating tendon overuse.

OBJECTIVE: This study investigated the effects of a therapeutic laser, passive stretching, and their combined treatment on the strength of Achilles tendons with overuse pathologies. BACKGROUND DATA: Tendinopathy involving overuse is usually treated with exercise and stretching, but there has been no report on the treatment effect of a therapeutic laser combined with passive stretching on managing this condition. Despite the beneficial effect of a therapeutic laser on healing tendons that have had traumatic injury, its effect on degenerative tendons is not known. METHODS: Twenty-five mature Sprague-Dawley (SD) rats were used, with 20 subjected to daily bipedal downhill running for 8 weeks, to induce Achilles overuse, and 5 as normal controls. The exercised rats were divided into four groups: 1, laser treatment; 2, passive stretching; 3, combined laser and stretching; and 4, no treatment, running controls. GaAlAs laser with 660 nm wavelength was applied to both Achilles tendons for 50 sec for Groups 1 and 3. Passive stretching of 20 times/10 sec of maximum ankle plantar flexion was applied to Groups 2 and 3. Treatments were applied after each running session for a a total of 56 treatment sessions. On week 9, the tendons were tested for load-relaxation, stiffness, and ultimate strength. RESULTS: Stiffness was different (p=0.01), difference in ultimate strength was marginally insignificant (p=0.07), and load-relaxation difference was not significant among groups. Post-hoc analyses revealed that the mean stiffness of all the four exercise groups was lower than the normal control, whereas the ultimate strength from the laser and combined laser and stretching was not different from that of the normal control group, but was higher than that of the passive stretching and no treatment groups. CONCLUSIONS: We conclude that a therapeutic laser and combined laser with passive stretching might slow down the decrease in Achilles tendon strength but would not be able to stop the pathological changes of overuse from developing.

Performing arts medicine - instrumentalist musicians: part III - case histories.

In parts I and II of this article series, the basic principles of examining musicians in a healthcare setting were reviewed [Dommerholt, J. Performing arts medicine - instrumentalist musicians: part I: general considerations. J. Bodyw. Mov. Ther., in press-a; Dommerholt, J. Performing arts medicine - instrumentalist musicians: part II: the examination. J. Bodyw. Mov. Ther., in press-b]. Part III describes three case reports of musicians with hand pain, interfering with their ability to play their instruments. The musicians consulted with a performing arts physiotherapist. Neither musician had a correct medical diagnosis if at all, when they first contacted the physiotherapist. Each musician required an individualized approach not only to establish the correct diagnosis, but also to develop a specific treatment program. The treatment programs included ergonomic interventions, manual therapy, trigger point therapy, and patient education. All musicians returned to playing their instruments without any residual pain or dysfunction.

Proper body mechanics from an engineering perspective.

The economic viability of the manual therapy practitioner depends on the number of massages/treatments that can be given in a day or week. Fatigue or injuries can have a major impact on the income potential and could ultimately reach the point which causes the practitioner to quit the profession, and seek other, less physically demanding, employment. Manual therapy practitioners in general, and massage therapists in particular, can utilize a large variety of body postures while giving treatment to a client. The hypothesis of this paper is that there is an optimal method for applying force to the client, which maximizes the benefit to the client, and at the same time minimizes the strain and effort required by the practitioner. Two methods were used to quantifiably determine the effect of using "poor" body mechanics (Improper method) and "best" body mechanics (Proper/correct method). The first approach uses computer modeling to compare the two methods. Both postures were modeled, such that the biomechanical effects on the practitioner's elbow, shoulder, hip, knee and ankle joints could be calculated. The force applied to the client, along with the height and angle of application of the force, was held constant for the comparison. The second approach was a field study of massage practitioners (n=18) to determine their maximal force capability, again comparing methods using "Improper and Proper body mechanics". Five application methods were tested at three different application heights, using a digital palm force gauge. Results showed that there was a definite difference between the two methods, and that the use of correct body mechanics can have a large impact on the health and well being of the massage practitioner over both the short and long term.

In vitro modeling of repetitive motion injury and myofascial release.

OBJECTIVE: In this study we modeled repetitive motion strain (RMS) and myofascial release (MFR) in vitro to investigate possible cellular and molecular mechanisms to potentially explain the immediate clinical outcomes associated with RMS and MFR. METHOD: Cultured human fibroblasts were strained with 8h RMS, 60s MFR and combined treatment; RMS+MFR. Fibroblasts were immediately sampled upon cessation of strain and evaluated for cell morphology, cytokine secretions, proliferation, apoptosis, and potential changes to intracellular signaling molecules. RESULTS: RMS-induced fibroblast elongation of lameopodia, cellular decentralization, reduction of cell to cell contact and significant decreases in cell area to perimeter ratios compared to all other experimental groups (p<0.0001). Cellular proliferation indicated no change among any treatment group; however RMS resulted in a significant increase in apoptosis rate (p<0.05) along with increases in death-associated protein kinase (DAPK) and focal adhesion kinase (FAK) phosphorylation by 74% and 58% respectively, when compared to control. These responses were not observed in the MFR and RMS+MFR group. Of the 20 cytokines measured there was a significant increase in GRO secretion in the RMS+MFR group when compared to control and MFR alone. CONCLUSION: Our modeled injury (RMS) appropriately displayed enhanced apoptosis activity and loss of intercellular integrity that is consistent with pro-apoptotic dapk-2 and FAK signaling. Treatment with MFR following RMS resulted in normalization in apoptotic rate and cell morphology both consistent with changes observed in dapk-2. These in vitro studies build upon the cellular evidence base needed to fully explain clinical efficacy of manual manipulative therapies.

Performing arts medicine - instrumentalist musicians part I - general considerations.

Performing arts medicine is a relatively new specialty addressing the medical needs of dancers, musicians, ice skaters, and gymnasts. This paper focuses on the role of healthcare providers in the diagnosis and therapeutic management of instrumentalist musicians. Musicians are at high risk for developing painful musculoskeletal problems, including pain and overuse injuries, entrapment and peripheral neuropathies, and focal dystonias. Musicians' careers are threatened, when they are no longer able to play their instrument because of pain and dysfunction. To appreciate music-related injuries, it is important that clinicians are familiar with the context of musicians' injuries and disorders. This is the first paper in a series of three. This paper discusses the importance of taking an extended history. The typical history procedures need to be broadened when interviewing musicians, and should include instrument-specific questions, and questions regarding practice habits, education, repertoire, and employment. The second article addresses the physical examination, while the third article provides three case reports of musicians with hand problems, which serve to illustrate the points made in the first two articles. The articles are illustrated with several tables and photographs of musicians to assist the reader in assessing instrumentalist musicians and determining the most appropriate course of action.

WITHDRAWN: Ergonomic and physiotherapeutic interventions for treating work-related complaints of the arm, neck or shoulder in adults.

BACKGROUND: Conservative interventions such as physiotherapy and ergonomic adjustments (such as keyboard adjustments or ergonomic advice) play a major role in the treatment of most work-related complaints of the arm, neck or shoulder (CANS). OBJECTIVES: This systematic review aims to determine whether conservative interventions have a significant impact on outcomes for work-related CANS in adults. SEARCH STRATEGY: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (March 2005) and Cochrane Rehabilitation and Related Therapies Field Specialised Register (March 2005), the Cochrane Controlled Trials Register (The Cochrane Library, Issue 1, 2005), PubMed, EMBASE, CINAHL, AMED and reference lists of articles. The date of the last search was March 2005. No language restrictions were applied. SELECTION CRITERIA: We included randomised controlled trials studying conservative interventions (e.g. exercises, relaxation, physical applications, biofeedback, myofeedback and work-place adjustments) for adults suffering CANS. DATA COLLECTION AND ANALYSIS: Two authors independently selected trials from the search yield, assessed the methodological quality using the Delphi list, and extracted relevant data. We pooled data or, in the event of clinical heterogeneity or lack of data, we used a rating system to assess levels of evidence. MAIN RESULTS: For this update we included six additional studies; 21 trials in total. Seventeen trials included people with chronic non-specific neck or shoulder complaints, or non-specific upper extremity disorders. Over 25 interventions were evaluated; five main subgroups of interventions could be determined: exercises, manual therapy, massage, ergonomics, and energised splint. Overall, the quality of the studies was poor.In 14 studies a form of exercise was evaluated, and contrary to the previous review we now found limited evidence about the effectiveness of exercises when compared to massage and conflicting evidence when exercises are compared to no treatment. In this update there is limited evidence for adding breaks during computer work; massage as add-on treatment on manual therapy, manual therapy as add-on treatment on exercises; and some keyboard designs when compared to other keyboards or placebo in participants with carpal tunnel syndrome. AUTHORS' CONCLUSIONS: There is limited evidence for the effectiveness of keyboards with an alternative force-displacement of the keys or an alternative geometry, and limited evidence for the effectiveness of exercises compared to massage; breaks during computer work compared to no breaks; massage as an add-on treatment to manual therapy; and manual therapy as an add-on treatment to exercises.

The Extended Rehabilitation Program (PRA ? Programa de ReabilitaçãoAmpliado) was developed in response to a demand from thePublic Labor Ministry (MPT) of the 12th District following reports ofa high rate (10%) of occupational diseases?especially RSI/WRULDand mental disorders in a meat-packing company in mid-western SantaCatarina. Since the establishment of a partnership between the INSS,Centro de Referência Estadual em Saúde do Trabalhador (CEREST/SC) --- the State Reference Center for Occupational Health (CEREST/SC), Universidade Federal de Santa Catarina (UFSC) --- the FederalUniversity of Santa Catarina (UFSC), and the 12th District MPT,the PRA was developed as a proposal of Conduct Adjustment Terms(TAC - Termo de Ajuste de Conduta). This is the only such projectin Brazil and has three aspects: 1) assistance; 2) monitoring; and 3)requalification. Eighteen professionals were part of a multidisciplinaryteam who offer such services as: physiotherapy, occupationaltherapy (OT), psychology, acupuncture, postural re-education, tai chichuan, massage therapy, circle dances, information groups, physicalconditioning, water exercises, supplementary therapies, and socialassistance. This program, starting in November of 2007 and endingin September of 2008, attended 425 persons. The main goals of thispaper are: 1) to delineate the structure of the ERP and its proceduresregarding the assistance and requalification aspects; and 2) to presentthe results. This is a cross-sectional, quantitative study collecting dataat two points ? the outset and the termination. Data was analyzed usingdescriptive and inferential statistics (mean and standard deviation),T-test, and chi-square. A large number of workers showed significantimprovement in quality of life, general health, functional capacity,depression, and increase in range of movement.

The 'Bunkie' test: assessing functional strength to restore function through fascia manipulation.

It has been speculated that repetitive patterns of movement will lead to specific patterns in fascia contraction, which, if it exceeds a specific limit, will lead to injury. Therapists working in the athletic environment are challenged to find ways not only to assess and measure fascia dysfunction, but also to restore functional strength by manipulating the fascia back to its neutral position. The 'Bunkie' test was developed over a period of 12 years to measure the function of the specific fascia lines in athletes. Numerous athletes from various sports were assessed and treated. Results have shown over the years that this test can be used successfully to find the cause of and treat injuries and to determine the progress of treatment in elite and recreational athletes.

Case study: musicians' playing-related injuries.

Professional and student musicians are at high risk of acquiring a playing-related injury at some point in their careers. Yet, specialized healthcare for musicians is scarce and expensive for most self-employed musicians. Diagnosing these injuries is challenging, and simply taking a break from an activity that has caused physical problems does not address the ergonomic and biomechanic causes of the problem. Under these circumstances, it is not surprising that musicians are reluctant to seek care, and when they do, lack trust in the care that is provided to them. This article is a case presentation of the experiences of a graduate student musician studying performance at a North American university. A narrative style is used to reflect the quality and nature of experiences this musician encountered, followed by a discussion of how to advance a more participatory and holistic approach to enabling return to function.

Integrative interventions for MSDs: nature, evidence, challenges & directions.

BACKGROUND: When applied to workplace interventions, integrative may be seen in various ways, requiring elucidation. METHODS: Identification of primary studies through systematic reviews, limited bibliographic literature searches, the Cochrane Occupational Health Field database on intervention studies, and authors' files. Focus was 2000 on. Categorization according to the Cochrane classes and lenses on integrative. Synthesis as narrative review. RESULTS: Examples of each lens on integrative were uncovered: biomechanical and psychosocial, multiple component, primary and secondary prevention, organizational, and system. Each contributed different understanding to the potential impacts on different knowledge, exposure, behavior, health and administrative outcomes. CONCLUSIONS: Considerable opportunities exist to expand the range of integrative interventions, particularly at the organizational and system levels, and incorporate a combination of knowledge transfer and exchange with intervention evaluation.

Occupational and physical therapy for work-related upper extremity disorders: how we can influence outcomes.

Upper extremity disorders in the workplace continue to be an economic strain on society. Physical and occupational therapy plays a crucial role in the management of the disorders. Medical providers should use therapists whose treatments demonstrate improvement in function and provide superior outcomes. Skilled therapy intervention requires that a therapist be able to identify and treat an injured worker in a holistic manner by looking at the whole individual, including issues that involve mechanical dysfunctions, psychosocial issues that include job satisfaction, and other age-related organic comorbidities. Therapists who work with injured employees must be highly skilled in identifying behavioral and organic disorders and must be confident in communicating these findings to various members of the health care team to help facilitate further medical testing.

Efficacy of dextrose prolotherapy in elite male kicking-sport athletes with chronic groin pain.

OBJECTIVE: To determine the efficacy of simple dextrose prolotherapy in elite kicking-sport athletes with chronic groin pain from osteitis pubis and/or adductor tendinopathy. DESIGN: Consecutive case series. SETTING: Orthopedic and trauma institute in Argentina. PARTICIPANTS: Twenty-two rugby and 2 soccer players with chronic groin pain that prevented full sports participation and who were nonresponsive both to therapy and to a graded reintroduction into sports activity. INTERVENTION: Monthly injection of 12.5% dextrose and 0.5% lidocaine into the thigh adductor origins, suprapubic abdominal insertions, and symphysis pubis, depending on palpation tenderness. Injections were given until complete resolution of pain or lack of improvement for 2 consecutive treatments. MAIN OUTCOME MEASURES: Visual analog scale (VAS) for pain with sports and the Nirschl Pain Phase Scale (NPPS), a measure of functional impairment from pain. RESULTS: The final data collection point was 6 to 32 months after treatment (mean, 17 mo). A mean of 2.8 treatments were given. The mean reduction in pain during sports, as measured by the VAS, improved from 6.3+/-1.4 to 1.0+/-2.4 ( P <.001), and the mean reduction in NPPS score improved from 5.3+/-0.7 to 0.8+/-1.9 ( P <.001). Twenty of 24 patients had no pain and 22 of 24 were unrestricted with sports at final data collection. CONCLUSIONS: Dextrose prolotherapy showed marked efficacy for chronic groin pain in this group of elite rugby and soccer athletes.

Conservative treatment for repetitive strain injury.

Various conservative treatment options for repetitive strain injury are widely used, despite questionable evidence of their effectiveness. This systematic review evaluates the effectiveness of these treatment options for relieving symptoms of repetitive strain injury and improving activities of daily living. Searches in Medline and Embase, with additional reference checking resulted in 15 eligible trials for this review. Methodological quality was assessed, and data-extraction was performed. With the use of a "best-evidence synthesis", no strong evidence was found for the effectiveness of any of the treatment options. There is limited evidence that multidisciplinary rehabilitation, ergonomic intervention measures, exercises, and spinal manipulation combined with soft tissue therapy are effective in providing symptom relief or improving activities of daily living. There is conflicting evidence for the effectiveness of behavioral therapy. In conclusion, little is known about the effectiveness of conservative treatment options for repetitive strain injury. To establish strong evidence, more high-quality trials are needed.
