Morpho-functional implications of myofascial stretching applied to muscle chains: A case study

BACKGROUND

Most lesions of the soft tissues, especially those at the muscle level, are due to the lack of elasticity of the connective tissue and fascia. Stretching is one of the most commonly used methods of treatment for such musculoskeletal issues.

OBJECTIVE

This study tracks the effects of stretching on the electromyographic activity of muscle chains, applied to a 24-year-old athlete diagnosed with the Haglund's disease.

METHOD

For the evaluation, we used visual examination and surface electromyography (maximum volumetric isometric contraction). The therapeutic intervention consisted in the application of the static stretching positions, which intended the elongation of the shortened muscle chains. The treatment program had a duration of 2 months, with a frequency of 2 sessions per week and an average duration of 60 minutes.

RESULTS

The posterior muscle chains recorded an increase in the EMG activity, while the anterior muscle chains tended to diminish their EMG activity. As a result of the applied treatment, all the evaluated muscle chains recorded a rebalancing of the electromyographic activity, demonstrating the efficiency of stretching as a method of global treatment of muscle chains.

CONCLUSIONS

By analysing all the data, we have come to the conclusion that static stretching is an effective treatment method for shortened muscle chains.

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.

Interval Throwing and Hitting Programs in Baseball: Biomechanics and Rehabilitation

Baseball injuries from throwing and hitting generally occur as a consequence of the repetitive and high-energy motions inherent to the sport. Biomechanical studies have contributed to understanding the pathomechanics leading to injury and to the development of rehabilitation programs. Interval-based throwing and hitting programs are designed to return an athlete to competition through a gradual progression of sport-specific exercises. Proper warm-up and strict adherence to the program allows the athlete to return as quickly and safely as possible.

[Eccentric exercises in the treatment of overuse injuries of the musculoskeletal system]

Overuse injuries of the musculoskeletal system are a common problem in both general population and among athletes. Researches made in the last decade have shown that overuse injuries are mainly caused by degenerative changes and not inflammation, as was thought before. Although they can be present everywhere in musculoskeletal system, overuse injuries are most often seen on tendons. The main goal of this article is to refer to latest guidelines in the treatment of overuse injuries, with special attention to eccentric exercise treatment program for most common tendinopathies (patellar tendinopathy, Achilles tendinopathy and lateral epicondylitis). The main reason is the fact that very good results are accomplished after eccentric exercises in the treatment of tendinopathies and are thus suggested as the first treatment option.

Application of wedged foot orthosis effectively reduces pain in runners with pronated foot: a randomized clinical study

OBJECTIVE

To examine the effects of foot orthosis intervention during a 60-minute running test in pronated-foot runners with overuse knee or foot pain during running.

DESIGN

A randomized, controlled design.

SETTING

Sports gym.

PARTICIPANTS

Twenty-four runners with pronated foot who experienced pain over anterior knee or foot region during running were recruited and randomized into the treatment, or the control, group.

INTERVENTIONS

A soft insole with a semi-rigid rearfoot medial wedge was given to the treatment group, and a soft insole without corrective posting was applied to the control group.

OUTCOME MEASURES

The immediate and short-term effects of orthosis application on incidence of pain, pain intensity and onset time were evaluated using the 60-minutes treadmill test.

RESULTS

Immediately after wearing the foot orthosis, pain incidence reduced in the treatment group but not in the control group (P = 0.04). After two weeks, seven (58%) subjects in the treatment group and one (8%) in the control group were free of pain during the test (P = 0.01). The pain intensity score decreased significantly after orthosis application, from 35.5 to 17.2 (immediate effect, P = 0.014), then to 12.3 (short-term effect, P < 0.001).

CONCLUSION

The rearfoot medially-wedged insole was a useful intervention for preventing or reducing painful knee or foot symptoms during running in runners with pronated foot.

Clinical concepts for treatment of the elbow in the adolescent overhead athlete

Injuries to the adolescent elbow are common because of the repetitive overuse inherent in many overhead sport activities. The management of these patients is greatly facilitated through a greater understanding of the demands placed on the upper extremity kinetic chain during these overhead activities as well as a detailed examination and rehabilitation for the entire upper extremity kinetic chain. Particular emphasis on improving rotator cuff strength and muscular endurance, along with scapular stabilization, is a critical part of elbow rehabilitation in these patients. In addition, the use of a strategic and progressive interval sport return program is necessary to minimize reinjury and return the adolescent overhead athlete to full function.

Stress fractures in runners

Running has many beneficial effects, including cardiovascular and skeletal health. Poor training technique and a variety of risk factors may predispose runners to lower-limb overuse injuries affecting muscle, tendon, and bone. Injuries to the bone include stress reactions to full-fledged stress fractures. This article is designed to provide an understanding of the general concepts involving bone strain, risk factor assessment, and evaluation and treatment strategies for the runner with a stress fracture. The second half of the article presents more detail regarding each specific fracture seen in runners. The ultimate goal of this article is to provide the basics regarding stress fractures in runners from pathophysiology and general guidelines of evaluation and treatment and provide a quick reference regarding the details of each specific fracture encountered in clinical practice.

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.

WITHDRAWN: Biopsychosocial rehabilitation for upper limb repetitive strain injuries in working age adults

BACKGROUND

Upper limb repetitive strain injury is a common problem in western countries, causing human suffering and huge economical losses. Patients with prolonged pain associated with repetitive tasks in the work place can face both psychological and physical difficulties. Different treatment programmes, physical, psychological, behavioural , social and occupational treatments have been developed and used to help these patients.

OBJECTIVES

The objective of this systematic review is to determine the effectiveness of biopsychosocial rehabilitation for upper limb repetitive strain injuries among working age adults.

SEARCH STRATEGY

The reviewed studies for this structured Cochrane review were identified from electronic bibliographic databases, the Science Citation Index, reference checking and consulting experts in the rehabilitation field. The original search was planned and performed for a more broad area of musculoskeletal disorders. Trials on repetitive strain injuries were separated afterwards.

SELECTION CRITERIA

Randomised controlled trials and controlled trials comparing biopsychosocial measures for the treatment of repetitive upper limb strain injury in working age adults

DATA COLLECTION AND ANALYSIS

Two experts in the field of rehabilitation evaluated the clinical relevance and applicability of the findings of the selected studies to actual clinical use. Two other blinded reviewers extracted the data and assessed the main results and the methodological quality of the studies using standardized forms. Finally, a qualitative analysis was performed to evaluate the level of scientific evidence for the effectiveness of biopsychosocial rehabilitation.

MAIN RESULTS

We found only two relevant studies that satisfied our criteria. They assessed the effectiveness of two specific interventions and were both considered as low quality trials. The clinical relevance of the included studies was also unsatisfactory. The level of scientific evidence for the effectiveness of biopsychosocial rehabilitation for repetitive strain injuries was limited. One small trial found that hypnosis supplementary to comprehensive treatment can decrease the intensity of pain for acute RSI in six weeks follow-up.

AUTHORS' CONCLUSIONS

We conclude that presently there appears to be little scientific evidence for the effectiveness of biopsychosocial rehabilitation on repetitive strain injuries. As RCTs on more intensive and comprehensive biopsychosocial treatment programmes for RSI are lacking, there does not seem to be reliable data for these interventions. There is a need for high quality trials in this field.

When golf hurts: musculoskeletal problems common to golfers

Golfers most frequently report injuries to the low back, nondominant shoulder, and elbow. Injury patterns differ between elite and recreational golfers; professional and elite golfers tend to experience golf injury related to overuse while amateur golfers may experience injury related to adverse swing technique and overuse. Therapeutic interventions should include assessment and treatment of deficiencies in the kinetic chain and professional instruction to modify swing technique. Changes in the swing may include instruction in a more efficient technique or shortening the swing to decrease biomechanical forces affecting the injured area.

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.

The (cost-)effectiveness of a lifestyle physical activity intervention in addition to a work style intervention on the recovery from neck and upper limb symptoms in computer workers

Background

Neck and upper limb symptoms are frequently reported by computer workers. Work style interventions are most commonly used to reduce work-related neck and upper limb symptoms but lifestyle physical activity interventions are becoming more popular to enhance workers health and reduce work-related symptoms. A combined approach targeting work style and lifestyle physical activity seems promising, but little is known on the effectiveness of such combined interventions.

Methods/design

The RSI@Work study is a randomised controlled trial that aims to assess the added value of a lifestyle physical activity intervention in addition to a work style intervention to reduce neck and upper limb symptoms in computer workers. Computer workers from seven Dutch companies with frequent or long-term neck and upper limb symptoms in the preceding six months and/or the last two weeks are randomised into three groups: (1) work style group, (2) work style and physical activity group, or (3) control group. The work style intervention consists of six group meetings in a six month period that take place at the workplace, during work time, and under the supervision of a specially trained counsellor. The goal of this intervention is to stimulate workplace adjustment and to improve body posture, the number and quality of breaks and coping behaviour with regard to high work demands. In the combined (work style and physical activity) intervention the additional goal is to increase moderate to heavy physical activity. The control group receives usual care. Primary outcome measures are degree of recovery, pain intensity, disability, number of days with neck and upper limb symptoms, and number of months without neck and upper limb symptoms. Outcome measures will be assessed at baseline and six and 12 months after randomisation. Cost-effectiveness of the group meetings will be assessed using an employer's perspective.

Discussion

This study will be one of the first to assess the added value of a lifestyle physical activity intervention in addition to a work style intervention in reducing neck and upper limb symptoms of computer workers. The results of the study are expected in 2007.

Upper extremity disorders in the workplace: costs and outcomes beyond the first return to work

BACKGROUND

Cumulative trauma disorders of the upper extremities (CTD) have become increasingly important in workers' compensation caseloads over the last two decades. Relative to occupational back pain, CTD have been much less studied.

METHODS

We analyzed post-injury employment patterns and return-to-work probabilities for a sample of Ontario workers with CTD, for up to five years after injury. Results for workers with CTD are compared to results for workers with back injuries or fractures.

RESULTS

Most workers with CTD return to work at least once, but a first return does not necessarily mark the end of work disability. Among workers absent at least once, 26% with CTD report a second injury-related absence, compared to 18% with back pain and 12% with fractures. After five years, focusing on first returns underestimates work-loss days associated with CTD by 32%.

CONCLUSIONS

A substantial proportion of workers with CTD or work-related back pain experience injury-related absences after their first return to work. Focusing on the first return to work is misleading for both injury groups, but even more so for CTD, as they appear to be even more susceptible to multiple spells of work absence.

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.

Treatment options in overuse injuries of the knee: patellofemoral syndrome, iliotibial band syndrome, and degenerative meniscal tears

Overuse injuries of the knee, particularly those of the extensor mechanism and iliotibial band, are commonplace in primary care and musculoskeletal practices. Effective treatment requires identification of all pertinent biomechanical factors contributing to overload and implementing measures to correct them.

Repeat Mild Traumatic Brain Injury

Determining when it is safe for an athlete to return to play (RTP) after concussion is one of the most difficult decisions facing the team physician. There is significant variability in the evaluation and management of mild traumatic brain injury (mTBI). In the past decade, a tremendous amount of sport-specific research has improved our understanding of mTBI. The advent of neuro-psychologic (NP) testing batteries designed to assess concussive injury has improved the assessment of cognitive dysfunction that occurs in the absence of structural brain abnormalities. The severity of injury is determined by the nature, burden, and duration of symptoms. Athletes must be asymptomatic and have a normal neurologic and cognitive evaluation prior to RTP. Several factors aid in making the RTP decision, including age, the severity of injury, and history of prior mTBIs. Given the potential complications of mTBI, the RTP decision must be made using a thoughtful, individualized process.

Prevention of delayed recovery and disability of work-related upper extremity disorders

There is always a psychological component to any illness or injury, and unless it is appropriately addressed, such factors can complicate or delay the recovery from a work-related illness or injury. When a worker experiences delayed recovery and unexpected disability, significant contributing psychosocial factors must be assessed for and managed appropriately. A maladaptive belief or understanding about the condition and disability by a patient presents an obstacle to successful treatment. Using cognitive behavioral therapy techniques may be an effective means of managing this challenge for the clinician.

Unstable isolated SLAP lesion: clinical presentation and outcome of arthroscopic fixation

PURPOSE

The purpose of this study was to describe the clinical presentation and sensitivity of testing of unstable isolated SLAP (superior labrum anterior posterior) lesions and to evaluate the efficacy of arthroscopic treatment.

TYPE OF STUDY

Case series.

METHODS

A retrospective review was made of 44 unstable SLAP lesions in 41 patients (40 male, 1 female) who did not have other pathologic shoulder findings. The mean follow-up period was 33 months (range, 25 to 67 months) and the mean age at the time of surgery was 24 years (range, 17 to 43 years). Twenty-six patients had an injury on the dominant shoulder and 3 had bilateral shoulder involvement. Arthroscopic fixation was performed with the use of a biodegradable tack (Suretac; Acufex, Mansfield, MA) in 14 cases, and with a screw-type metallic suture anchor (mini-Revo; Linvatec, Largo, FL) in 30 cases.

RESULTS

Pain (100%) and clicking (57%) were the most common symptoms. The compression-rotation test was positive in 84% of the patients before surgery. The average UCLA score at the last follow-up was 32.3 points; 22 cases were graded excellent, 16 good, and 6 poor. Based on the postoperative performance data collected from 33 athletes, 25 of them (76%) were able to return to their athletic activities. Among them, throwing athletes showed statistically better performance than did nonthrowing athletes (P = .011).

CONCLUSIONS

Pain, followed by clicking, was the most common symptom, and the most common sign was a positive compression rotation test. Arthroscopic treatment of unstable isolated SLAP lesions resulted in good or excellent UCLA scores in 86% of the patients. Throwing athletes showed more satisfactory results than nonthrowing athletes.

LEVEL OF EVIDENCE

Type IV, case series with no, or historical, control group.

Basis for an FCE methodology for patients with work-related upper limb disorders

A reported reduction in work-related functional capacity in Work-related Upper Limb Disorders (WRULD) patients is among the most common problems in WRULD. The extent to which this reduction in functional capacity can be objectified remains unknown. A validated instrument to test functional capacity in this patient group is unavailable. The objective of this study was to design a Functional Capacity Evaluation (FCE) for WRULD patients working with Visual Display Units (VDU) and provide evidence for content validity. A review to epidemiological literature was conducted to identify physical risk factors for VDU-related WRULD. The results indicate that physical risk factors were related to repetition, duration, working in awkward and static positions and forceful movements of the upper extremity and neck. An FCE was designed based on the risk factors identified. Eight tests were selected to cover all risk factors: the overhead lift, overhead work, repetitive reaching, handgrip strength, finger strength, wrist extension strength, fingertip dexterity, and a hand and forearm dexterity test. Content validity of this FCE was established by providing the rationale, specific objectives and operational definitions of the FCE. Further research is needed to establish reliability and other aspects of validity of the WRULD FCE.

Treatment of glenohumeral subluxation using electrothermal capsulorrhaphy

PURPOSE

The purpose of this study was to review the results of a relatively homogenous group of patients with glenohumeral subluxation without labral pathology who were treated with an electrothermal capsulorrhaphy procedure.

TYPE OF STUDY

Case series without controls.

METHODS

From 1997 to 1998, 42 patients underwent electrothermal capsulorrhaphy using a monopolar radiofrequency probe (Oratec Interventions, Menlo Park, CA). Patients with prior capsular repairs, labral pathology that required repair, or capsular avulsion injuries were excluded from the study. Thirty-one patients met the inclusion criteria. Patients had a minimum of 2 years of follow-up (mean, 25 months), and a mean age of 25 years (range, 16 to 38 years). All of the patients had previously failed conservative treatment. There were 25 patients with unidirectional anterior instability, 2 patients with unidirectional inferior instability, 1 patient with unidirectional posterior instability, and 3 patients with multidirectional instability. The patients were assessed using a modified American Shoulder and Elbow Surgeons (ASES) score that examined pain (30 points), function (60 points), and patient satisfaction (10 points). In addition, subjective stability was assessed using a 10-point scale.

RESULTS

The average modified ASES score increased to 88 points from 56 preoperatively (P < .01). The average subjective stability scale increased to 8.5 from 4.4 preoperatively (P < .01). Nineteen patients (61%) had an excellent result, 4 (13%) had a good result, 5 (16%) had a fair result, and 3 (10%) had a poor result; 22 of 26 patients who participated in sports were able to return to their preinjury level of play. The subset of patients with isolated anterior instability had results similar to the overall group. There were no instances of axillary neuritis or other neurologic injury.

CONCLUSIONS

In carefully selected patients with shoulder instability, including unidirectional anterior instability without associated labral pathology, electrothermal capsulorrhaphy was effective and had few complications.

LEVEL OF EVIDENCE

Level IV, case series without controls.

Evidence-Based Treatment of Hip and Pelvic Injuries in Runners

The runner is especially at risk for development of injury to the hip and pelvis secondary to chronic repetitive microtrauma. The key to treatment is establishing complete and accurate diagnosis, and, in particular, identifying the functional biomechanical deficits in the kinetic chain that contribute to this repetitive microtrauma. A long-term successful outcome and prevention of reinjury are more likely if the focus of rehabilitation is on the restoration of the functional kinetic chain, rather than on a specific injured tissue. For example, the typical treatment of "iliotibial band syndrome" is a stretching protocol that frequently is unsuccessful in the long-term improvement of symptoms. A functional biomechanical approach might identify that the injured runner has lack of calcaneal eversion and a structurally rigid supinated foot. These functional biomechanical deficits would lead to inadequate internal rotation of the tibia and femur and result in inhibition or decreased recruitment of the gluteal muscles, in particular the gluteus medius. Restoring pronation throughout the lower extremity would require joint play techniques or functional joint mobilizations for the foot and ankle. In addition, a running shoe with a cushioned heel may be necessary to promote pronation and to attenuate shock. Exercises that integrate foot and hip function, including balance reaches, lunges and step-downs, are prescribed to stimulate the gluteus medius and other gluteals in positions that simulate running. Activities that are done in this manner activate the entire functional kinetic chain of muscles and joints. The nonoperative sports medicine specialist, in particular the physiatrist and physical therapist, are in an excellent position to integrate treatment of the entire functional kinetic chain through a thorough biomechanical evaluation and comprehensive rehabilitation of the injured runner. Additional training in the areas of biomechanical evaluation and functional biomechanical deficits should be sought, because residency and even many fellowship-trained programs often overlook these important areas. Finally, the injured runner is best taken care of in a setting in which different sports medicine specialists are available and work well as a team. No one sports medicine specialist can provide all of the needs to the injured runner.

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.

Evaluation of an occupational rehabilitation program

OBJECTIVE

The purpose of this study was to report the findings of a program evaluation for an occupational rehabilitation program in the Midwest.

METHOD

An ex-post facto chart review was performed on 50 charts using demographic data, results from tests of performance and pain measures, and data from patient satisfaction questionnaires to find evidence of excellence in the program, and to identify areas for improvement.

RESULTS

Over 97% of the participants actually completed the program and 76% returned to work within 3 months after program completion. Ninety-two percent indicated overall satisfaction with the program, and all aspects of the program were rated with a mean score of 4.25 or above on a 1 to 5 Likert scale. Evaluation of perceived pain scales of the participants indicate no discernable relationship between intensity of pain and successful return to work.

CONCLUSION

The program showed a high completion rate, a high return to work rate, and high levels of patient satisfaction. Suggestions for improvement include an increase in use of real and simulated work activities, better documentation of pain measures, better programs to address psychosocial issues, lengthening the program, and increased communication with case managers and professionals outside of the work program.

Golf injuries of the upper extremity

Golf has demonstrated increasing popularity and with this heightened enthusiasm has come an increased awareness of the significant number of injuries associated with playing golf. While back injuries represent the most commonly injured specific body part, upper extremity injuries are most frequent overall and the most likely to result in loss of play. Patterns of injury differ based on level of play and time spent playing or practicing golf. Among golf professionals, the hand/wrist is the most commonly injured upper extremity structure. Among amateurs, the elbow is most commonly injured. The vast majority of upper extremity injuries are due to overuse. Age, ability, equipment, and swing mechanics also play contributing roles. Most upper extremity golf injuries can be successfully treated with appropriate cessation or modification of play, anti-inflammatory modalities, and rehabilitation. Surgical treatment is rarely required, but if needed can prove successful in a high percentage of patients.

Computer use associated with poor long-term prognosis of conservatively managed lateral epicondylalgia

STUDY DESIGN

Multicenter prospective design with a cohort of patients with lateral epicondylalgia commencing physical therapy.

OBJECTIVE

To identify key factors associated with long-term prognosis of conservatively managed lateral epicondylalgia.

BACKGROUND

The response to conservative management of lateral epicondylalgia is inconsistent and the rate of recovery varies widely among individuals. The reasons for these discrepancies are not understood. The identification of factors associated with prognosis will aid in the prediction of patient outcomes.

METHODS AND MEASURES

Sixty patients with lateral epicondylalgia, recruited from 9 sports medicine clinics and 2 hospital outpatient physical therapy departments in Ontario, Canada, were followed for 6 months. A baseline clinical assessment was conducted on each participant using standard physical therapy techniques. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and a 100-mm pain visual analog scale (VAS) were completed at baseline and 6 months later.

RESULTS

The key factor associated with both 6-month DASH and pain VAS scores was repetitive-work tasks (DASH, 9.8 [P < .011; pain VAS, 13.1 mm [P = .0105]). A subanalysis indicated that women were more likely than men to have cervical joint signs and, among women, positive cervical articular signs were also associated with higher final DASH and pain VAS scores.

CONCLUSIONS

Although many of the participants identified sports activities as the cause of their injury, these findings emphasize the importance that a patient's work tasks can have on recovery of lateral epicondylalgia. This would suggest that management should perhaps focus on work stations, postures, and behaviors.

Physical exercise and health education for neck and shoulder complaints among sedentary workers

OBJECTIVE

To assess the effectiveness of 3 different health promotion exercise programs for work-related shoulder and neck pain.

DESIGN

Comparative study design.

SUBJECTS

A total of 178 employees were recruited and grouped.

METHODS

Those in the "Self-exercise group" (n = 56) were given a lecture about the exercise program and then performed the program by themselves during their office break. "Team-exercise group I" (n = 69) performed the program once under the supervision of a physiotherapist after the lecture. "Team-exercise group II" (n = 14) performed the program twice; once under a physiotherapist's supervision. A modified Nordic questionnaire, pain threshold and cervical range of motion were used to evaluate the effect of intervention. There were 39 subjects in the reference group.

RESULTS

When daily change of pain threshold (post-work-pre-work) was treated as an improvement index, the odds ratios for the self-exercise group, team-exercise group I and team-exercise group II were 1.39, 4.63 (p < 0.05) and 7.06 (p < 0.05), respectively, compared with the reference group. A dose-response effect of intervention intensity was demonstrated.

CONCLUSION

An intensive team-exercise program is beneficial in reducing neck and shoulder symptoms in sedentary workers.

Comparison of effects of exercise programme, pulsed ultrasound and transverse friction in the treatment of chronic patellar tendinopathy

OBJECTIVE

To compare the effectiveness of an exercise programme, pulsed ultrasound and transverse friction in the treatment of chronic patellar tendinopathy.

DESIGN

Randomized controlled trial.

SETTING

Rheumatology and Rehabilitation Centre.

SUBJECTS

This study was carried out with 30 patients who had chronic patellar tendinopathy. They were randomized into three groups.

INTERVENTIONS

Group A (n = 10) was treated with exercise programme. Pulsed ultrasound was given to group B (n = 10). Group C (n = 10) received transverse friction. All patients received three treatments per week for four weeks.

OUTCOMES

Patients' pain was evaluated at the end of the four-week course of treatment (week 4), one month (week 8) and three months (week 16) after the end of treatment.

RESULTS

The exercise programme was statistically significantly better than the other two treatments at the end of treatment (chi2 = 12.21, p < 0.01), one month (chi2 = 23.2, p < 0.001) and three months (chi2 = 23.2, p < 0.001) after the end of the treatment.

CONCLUSION

Although the results suggested that the exercise programme was more effective treatment than ultrasound and transverse friction at the end of the treatment as well as at the follow-ups, future controlled studies are needed to establish the relative and absolute effectiveness of each of the three treatment interventions.

Exploratory analysis to identify factors impacting return-to-work outcomes in cases of cumulative trauma disorder

Current findings suggest that cumulative trauma disorders are multifaceted and have less predictable outcomes than trauma cases. The purpose of this study was to attempt to identify emerging patterns and predictive relationships in this diagnostic group that might be worthy of eventual prospective research. The data source was a comprehensive electronic database containing clinical information collected at point of care over a four-year period. A retrospective analysis was performed on 459 workers' compensation cases with upper extremity cumulative trauma disorders and a subset of 312 with carpal tunnel syndrome. The outcome criterion was return to work as a dichotomous variable. Only two significant correlations with return to work were found: the therapist's estimate of rehabilitation potential and the patient's outcome expectation of the ability to work. Further investigation of the role of beliefs and expectations in the therapeutic process would be a productive area for prospective study.

[Evaluative research on occupational rehabilitation: the effectiveness of a health care service subject to dismantlement]

This article deals with the results obtained from 1995 to 1997 by an innovative occupational rehabilitation model for individuals with repetitive strain injury/work related musculoskeletal disorder (RSI/WRMD), developed by the Campinas Occupational Rehabilitation Center under the Brazilian National Institute for Social Security. The study had two objectives: 1) to reconstruct the program as a precondition for evaluation and 2) to evaluate the model's effectiveness in reestablishing the autonomy of individuals with RSI/WRMD. The methodology involved document analysis in order to reconstruct the program's background in terms of problem identification, organizational participation, awareness-raising, staff characteristics and responsibilities, and profile of the clientele. An analysis of 221 patient files provided the basis for constructing an evaluative instrument consisting of different dimensions, variables, and indicators, which was applied to a sample of 47 patient histories prior and subsequent to rehabilitative intervention. High effectiveness was observed in the model, with variations in the different target dimensions.

[Evidence based evaluation of conservative treatment options for patellar tendinitis syndromes]

INTRODUCTION

Patellar tendinopathy causes substantial morbidity in both professional and recreational athletes. There is no consensus about conservative treatment strategies for this condition.

METHODS

With the help of the evidence-based medicine method it is estimated whether conservative treatment is appropriate for treating pain in this condition.

RESULTS

5 specialist articles that matched the clinical question were found in medical databases. One article was analyzed for clinical relevance. The evaluation showed that physiotherapeutic treatment of pain in combination with additional iontophoresis is more promising than physiotherapy alone.

DISCUSSION

Current evidence suggests that traditional physiotherapy should be combined with additional therapeutic treatment. This requires further randomized prospective, placebo-controlled trials in order to confirm its efficiency. Prognostic effects of treatments should be included into these studies.

Effect of sensory discrimination training on structure and function in patients with focal hand dystonia: a case series

OBJECTIVE

To measure the effects of sensorimotor training based on the principles of neuroplasticity for patients with focal hand dystonia.

DESIGN

Case series of 3 subjects with focal hand dystonia of the left hand, compared with age-matched normative controls.

SETTING

Outpatient clinic.

PARTICIPANTS

Three consecutive clinic patients-musicians with focal hand dystonia-who described a history of repetitive practice and performance (2 women; ages, 23 y and 35 y; 1 man; age, 24 y).

INTERVENTION

Subjects were asked to stop performing the tasks that caused the abnormal movements, to participate in a wellness program (aerobics, postural exercises, stress free hand use), and to carry out supervised, attended, individualized, repetitive sensorimotor training activities at least once week for 12 weeks and reinforced daily at home.

MAIN OUTCOME MEASURES

Standard tests documenting somatosensory hand representation, target-specific hand control, and clinical function.

RESULTS

On the affected side, the 3 subjects improved an average of 86.8% on somatosensory hand representation, 117% on target-specific performance, 23.9% on fine motor skills, 22.7% on sensory discrimination, 31.9% on musculoskeletal skills, and 32.3% on independence. All 3 subjects improved 10% or more on 90% of the subtests with 20% improvement on 50% of the subtests.

CONCLUSION

Individuals with focal hand dystonia who have a history of repetitive hand use can improve cortical somatosensory responses and clinical motor function after individualized sensorimotor training consistent with the principles of neural adaptation.

What affects return to work for graduates of a pain management program with chronic upper limb pain?

Chronic upper limb pain often causes work loss, and return to work after pain management is disappointingly low. This study aimed to identify patient characteristics and beliefs contributing to return to work or nonreturn. A total of 103 (66%) ex-patients with CULP, who had completed a pain management program, agreed to telephone interview. Participants were predominantly female and in middle years; 53.4% were working part- or full-time. Their responses were related to pre- and posttreatment psychological and disability variables. Those patients who had returned to work, compared to those who had not, were more likely to have been working shortly before treatment (chi 2 = 36.77, p < 0.00001). They were more psychologically robust and were more confident of managing pain (t = 4.55, p < 0.001), and catastrophized less (t = 2.21, p = 0.029). They were also more optimistic about being capable of work (u = 566, p < 0.0001) and of overcoming obstacles to work (u = 889, p = 0.0103). Workers and nonworkers were not differentiated by expectations of support from their immediate line manager, although nonworkers doubted support available from colleagues. Overall, despite generalization of pain management strategies in nonwork activity, return to work depended on specific beliefs concerning work-relevant strategies.

Rehabilitation programs and prevention strategies in adolescent throwing athletes

A specific and early diagnosis must be made in the injured skeletally immature throwing athlete. A well-outlined program of rest, rehabilitation, and proper throwing techniques should be implemented and continued. Overuse injuries are preventable when biomechanics are sound and pitch counts are done with the limits enforced. Guidelines for inning limits, number of pitches, rest intervals, and throwing programs should be followed for adolescent pitchers because adolescents differ from adults. Information is included for specifications of the ball and helmet, as well as chest protective equipment. The goal should be for the Little League players to have fun and be injury free as they are competing, which gives them the best experience and allows continuation of athletic activities for a lifetime.
