A controlled clinical pilot trial to study the effectiveness of ice as a supplement to the exercise programme for the management of lateral elbow tendinopathy

The effects of the addition of Mulligan mobilization with movement to exercise on elbow pain and function associated with lateral elbow tendinopathy

BACKGROUND

Mulligan mobilization with movement (MWM) and eccentric exercise (EE) have been shown to be effective for the treatment of chronic lateral elbow tendinopathy (LET). However, the addition of MWM to EE effects on LET remained unknown. The objective of the study was to determine the effects of adding of Mulligan mobilization with movement to eccentric exercise for the treatment of LET.

METHODS

In this quasi-experimental study, thirty participants with unilateral LET were assigned into two groups: 15 in MWM (received MWM + EE) (7 M and 8 F, mean age 36.8 ± 8.3 years) and 15 in EE (9 M and 6 F, mean age 46 ± 8.1 years). Both groups received education about painful activities and eccentric exercise, while the MWM group received MWM with the same eccentric exercise as the EE group. The visual analog scale (VAS) and the patient-rated tennis elbow evaluation (PRTEE) were used to assess pain and upper limb function, respectively, at baseline and at the end of 4 weeks. The data was analyzed using an independent t-test and a paired t-test.

RESULTS

There was no significant difference (p > 0.05) between groups at baseline. At the end of 4 weeks, significant and clinically meaningful improvements in pain and function were observed for both groups (p < 0.001); however, MWM group showed much better results in VAS (p < 0.001, d = 1.3) and PRTEE (p < 0.001, d = 5.2) CONCLUSION: This study showed that adding MWM to eccentric exercise resulted in enhanced pain reduction and improved function of the upper limb.

Manual therapy and exercise for lateral elbow pain

BACKGROUND

Manual therapy and prescribed exercises are often provided together or separately in contemporary clinical practice to treat people with lateral elbow pain.

OBJECTIVES

To assess the benefits and harms of manual therapy, prescribed exercises or both for adults with lateral elbow pain.

SEARCH METHODS

We searched the databases CENTRAL, MEDLINE and Embase, and trial registries until 31 January 2024, unrestricted by language or date of publication.

SELECTION CRITERIA

We included randomised or quasi-randomised trials. Participants were adults with lateral elbow pain. Interventions were manual therapy, prescribed exercises or both. Primary comparators were placebo or minimal or no intervention. We also included comparisons of manual therapy and prescribed exercises with either intervention alone, with or without glucocorticoid injection. Exclusions were trials testing a single application of an intervention or comparison of different types of manual therapy or prescribed exercises.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies for inclusion, extracted trial characteristics and numerical data, and assessed study risk of bias and certainty of evidence using GRADE. The main comparisons were manual therapy, prescribed exercises or both compared with placebo treatment, and with minimal or no intervention. Major outcomes were pain, disability, heath-related quality of life, participant-reported treatment success, participant withdrawals, adverse events and serious adverse events. The primary endpoint was end of intervention for pain, disability, health-related quality of life and participant-reported treatment success and final time point for adverse events and withdrawals.

MAIN RESULTS

Twenty-three trials (1612 participants) met our inclusion criteria (mean age ranged from 38 to 52 years, 47% female, 70% dominant arm affected). One trial (23 participants) compared manual therapy to placebo manual therapy, 12 trials (1124 participants) compared manual therapy, prescribed exercises or both to minimal or no intervention, six trials (228 participants) compared manual therapy and exercise to exercise alone, one trial (60 participants) compared the addition of manual therapy to prescribed exercises and glucocorticoid injection, and four trials (177 participants) assessed the addition of manual therapy, prescribed exercises or both to glucocorticoid injection. Twenty-one trials without placebo control were susceptible to performance and detection bias as participants were not blinded to the intervention. Other biases included selection (nine trials, 39%, including two quasi-randomised), attrition (eight trials, 35%) and selective reporting (15 trials, 65%) biases. We report the results of the main comparisons. Manual therapy versus placebo manual therapy Low-certainty evidence, based upon a single trial (23 participants) and downgraded due to indirectness and imprecision, indicates manual therapy may reduce pain and elbow disability at the end of two to three weeks of treatment. Mean pain at the end of treatment was 4.1 points with placebo (0 to 10 scale) and 2.0 points with manual therapy, MD -2.1 points (95% CI -4.2 to -0.1). Mean disability was 40 points with placebo (0 to 100 scale) and 15 points with manual therapy, MD -25 points (95% CI -43 to -7). There was no follow-up beyond the end of treatment to show if these effects were sustained, and no other major outcomes were reported. Manual therapy, prescribed exercises or both versus minimal intervention Low-certainty evidence indicates manual therapy, prescribed exercises or both may slightly reduce pain and disability at the end of treatment, but the effects were not sustained, and there may be little to no improvement in health-related quality of life or number of participants reporting treatment success. We downgraded the evidence due to increased risk of performance bias and detection bias across all the trials, and indirectness due to the multimodal nature of the interventions included in the trials. At four weeks to three months, mean pain was 5.10 points with minimal treatment and manual therapy, prescribed exercises or both reduced pain by a MD of -0.53 points (95% CI -0.92 to -0.14, I2 = 43%; 12 trials, 1023 participants). At four weeks to three months, mean disability was 63.8 points with minimal or no treatment and manual therapy, prescribed exercises or both reduced disability by a MD of -5.00 points (95% CI -9.22 to -0.77, I2 = 63%; 10 trials, 732 participants). At four weeks to three months, mean quality of life was 73.04 points with minimal treatment on a 0 to 100 scale and prescribed exercises reduced quality of life by a MD of -5.58 points (95% CI -10.29 to -0.99; 2 trials, 113 participants). Treatment success was reported by 42% of participants with minimal or no treatment and 57.1% of participants with manual therapy, prescribed exercises or both, RR 1.36 (95% CI 0.96 to 1.93, I2 = 73%; 6 trials, 770 participants). We are uncertain if manual therapy, prescribed exercises or both results in more withdrawals or adverse events. There were 83/566 participant withdrawals (147 per 1000) from the minimal or no intervention group, and 77/581 (126 per 1000) from the manual therapy, prescribed exercises or both groups, RR 0.86 (95% CI 0.66 to 1.12, I2 = 0%; 12 trials). Adverse events were mild and transient and included pain, bruising and gastrointestinal events, and no serious adverse events were reported. Adverse events were reported by 19/224 (85 per 1000) in the minimal treatment group and 70/233 (313 per 1000) in the manual therapy, prescribed exercises or both groups, RR 3.69 (95% CI 0.98 to 13.97, I2 = 72%; 6 trials).

AUTHORS' CONCLUSIONS

Low-certainty evidence from a single trial in people with lateral elbow pain indicates that, compared with placebo, manual therapy may provide a clinically worthwhile benefit in terms of pain and disability at the end of treatment, although the 95% confidence interval also includes both an important improvement and no improvement, and the longer-term outcomes are unknown. Low-certainty evidence from 12 trials indicates that manual therapy and exercise may slightly reduce pain and disability at the end of treatment, but this may not be clinically worthwhile and these benefits are not sustained. While pain after treatment was an adverse event from manual therapy, the number of events was too small to be certain.

Exercise therapy for tendinopathy: a mixed-methods evidence synthesis exploring feasibility, acceptability and effectiveness

Background

Tendinopathy is a common, painful and functionally limiting condition, primarily managed conservatively using exercise therapy.

Review questions

(i) What exercise interventions have been reported in the literature for which tendinopathies? (ii) What outcomes have been reported in studies investigating exercise interventions for tendinopathy? (iii) Which exercise interventions are most effective across all tendinopathies? (iv) Does type/location of tendinopathy or other specific covariates affect which are the most effective exercise therapies? (v) How feasible and acceptable are exercise interventions for tendinopathies?

Methods

A scoping review mapped exercise interventions for tendinopathies and outcomes reported to date (questions i and ii). Thereafter, two contingent systematic review workstreams were conducted. The first investigated a large number of studies and was split into three efficacy reviews that quantified and compared efficacy across different interventions (question iii), and investigated the influence of a range of potential moderators (question iv). The second was a convergent segregated mixed-method review (question v). Searches for studies published from 1998 were conducted in library databases (n = 9), trial registries (n = 6), grey literature databases (n = 5) and Google Scholar. Scoping review searches were completed on 28 April 2020 with efficacy and mixed-method search updates conducted on 19 January 2021 and 29 March 2021.

Results

Scoping review - 555 included studies identified a range of exercise interventions and outcomes across a range of tendinopathies, most commonly Achilles, patellar, lateral elbow and rotator cuff-related shoulder pain. Strengthening exercise was most common, with flexibility exercise used primarily in the upper limb. Disability was the most common outcome measured in Achilles, patellar and rotator cuff-related shoulder pain; physical function capacity was most common in lateral elbow tendinopathy. Efficacy reviews - 204 studies provided evidence that exercise therapy is safe and beneficial, and that patients are generally satisfied with treatment outcome and perceive the improvement to be substantial. In the context of generally low and very low-quality evidence, results identified that: (1) the shoulder may benefit more from flexibility (effect sizeResistance:Flexibility = 0.18 [95% CrI 0.07 to 0.29]) and proprioception (effect sizeResistance:Proprioception = 0.16 [95% CrI -1.8 to 0.32]); (2) when performing strengthening exercise it may be most beneficial to combine concentric and eccentric modes (effect sizeEccentricOnly:Concentric+Eccentric = 0.48 [95% CrI -0.13 to 1.1]; and (3) exercise may be most beneficial when combined with another conservative modality (e.g. injection or electro-therapy increasing effect size by ≈0.1 to 0.3). Mixed-method review - 94 studies (11 qualitative) provided evidence that exercise interventions for tendinopathy can largely be considered feasible and acceptable, and that several important factors should be considered when prescribing exercise for tendinopathy, including an awareness of potential barriers to and facilitators of engaging with exercise, patients' and providers' prior experience and beliefs, and the importance of patient education, self-management and the patient-healthcare professional relationship.

Limitations

Despite a large body of literature on exercise for tendinopathy, there are methodological and reporting limitations that influenced the recommendations that could be made.

Conclusion

The findings provide some support for the use of exercise combined with another conservative modality; flexibility and proprioception exercise for the shoulder; and a combination of eccentric and concentric strengthening exercise across tendinopathies. However, the findings must be interpreted within the context of the quality of the available evidence.

Future work

There is an urgent need for high-quality efficacy, effectiveness, cost-effectiveness and qualitative research that is adequately reported, using common terminology, definitions and outcomes.

Responsiveness and Minimally Important Changes for Persian-version of Patient-Rated Tennis Elbow Evaluation Questionnaire in Patients with Lateral Elbow Tendinopathy Following Physiotherapy Intervention

BACKGROUND

Evaluating responsiveness and calculating minimally important change (MIC) for the Persian-version of the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire following physiotherapy in patients with lateral elbow tendinopathy (LET).

METHODS

We enrolled 82 patients with LET to complete the PRTEE. After completing four weeks of physiotherapy, all patients were reevaluated by the PRTEE. The patients also rated their changes on a 7-point global rating of change scale (GRoC). The receiver operating characteristic (ROC) curve and correlation analysis were used for evaluating the responsiveness. The MIC was determined by determining a desirable cutoff on the ROC curve.

RESULTS

The results showed a moderate relationship (Spearman's correlation coefficient= 0.43-0.56) of total PRTEE, pain subscale, and function subscale with the GRoC scale. The total PRTEE, pain subscale, and function subscale revealed an area under the curve of 0.87, 0.82, and 0.83, respectively. We found the MICs 31.33, 14.5, and 15.5 points for total PRTEE, pain subscale, and function subscale, respectively.

CONCLUSION

The Persian-version of the PRTEE questionnaire has acceptable responsiveness and can measure changes in patients with LET following physiotherapy. We advocate using the PRTEE questionnaire in both clinical settings and research.

Direct Effect of Local Cryotherapy on Muscle Stimulation, Pain and Strength in Male Office Workers with Lateral Epicondylitis, Non-Randomized Clinical Trial Study

Background: Local cryotherapy (LC) is one of the physiotherapeutic methods used in the conservative treatment of lateral epicondylitis (LE). The aim of the study was to verify the direct effect of a single LC procedure on the clinical symptoms of lateral epicondylitis enthesopathy (pain, pain free grip, PFG) and its effect on the bioelectrical properties of the wrist extensor muscles at rest, on maximal contraction and isometric contraction during fatigue. Methods: The study group was 28 men (35.4 ± 6.13 years) with confirmed unilateral epicondylitis. The performed procedures included the assessment of pain (visual analogue scale, VAS), PFG and ARMS (root-mean-square amplitude) and mean frequencies (MNF) of the sEMG signal before (T0) and after (T1) LC on the side with enthesopathy (ECRE) and without enthesopathy (ECRN/E). Results: There was an increase in the ARMS values of the signals recorded during rest and MVC from the ECR muscles both with and without enthesopathy (p = 0.0001, p = 0.006), an increased PFG after LC only on the side with LE (p < 0.0001) and decreased pain (p < 0.0001). During isometric fatigue contraction, a higher ARMS on both the ECRE side (p < 0.0001) and the ECRN/E side (p < 0.0001) was observed after LC treatment, and a lower MNF was observed on both the ECRN/E side (p < 0.0001) and the ECRE side (p < 0.0001) after LC. Conclusions: LC reduces the pain and increases PFG and muscle excitation expressed by ARMS and seems to delay muscle fatigue.

Lateral epicondylitis: New trends and challenges in treatment

Lateral epicondylitis (LE) is a chronic aseptic inflammatory condition caused by repetitive microtrauma and excessive overload of the extensor carpi radialis brevis muscle. This is the most common cause of musculoskeletal pain syndrome in the elbow, inducing significant pain and limitation of the function of the upper limb. It affects approximately 1-3% of the population and is frequently seen in racquet sports and sports associated with functional overload of the elbow, such as tennis, squash, gymnastics, acrobatics, fitness, and weight lifting. Typewriters, artists, musicians, electricians, mechanics, and other professions requiring frequent repetitive movements in the elbow and wrists are also affected. LE is a leading causation for absence from work and lower sport results in athletes. The treatment includes a variety of conservative measures, but if those fail, surgery is indicated. This review summarizes the knowledge about this disease, focusing on risk factors, expected course, prognosis, and conservative and surgical treatment approaches.

Comparison of the effectiveness of peloid therapy and kinesio taping in tennis elbow patients: a single-blind controlled study

This study aimed to compare the peloid therapy and kinesio tape treatments in chronic lateral epicondylitis. While home exercise program and cold application were applied to the control group, peloid therapy (5 days a week for 3 weeks at 45 °C for 30 min each day, a total of 15 treatment days) was applied in addition to the first group, and kinesio taping (6 treatment days 2 times a week) was applied to the second group. Patients were evaluated with visual analog scale (VAS), grip strength with Jamar hydraulic dynamometer, Arm, Shoulder, and Hand Disabilities (DASH), quality of life in Short Form-36 (SF-36), and Patient-Rated Forearm Evaluation Questionnaire (PRFEQ) was recorded before treatment, after treatment (third week), and 1 month after the end of treatment. In this study, 156 patients with chronic lateral epicondylitis were included. In the follow-up of the patients, there was a statistically significant improvement in the hand grip strength, DASH, PRFEQ, VAS, and SF-36 scores in the 1st month follow-up after the treatment compared to the pre-treatment control in all groups (p < 0.001). At the end of the treatment, the hand grip strength (p = 0.002), DASH (p < 0.001), PRFEQ pain (p < 0.001) and function (p = 0.007), SF-36 physical health (p = 0.002) scores were statistically significant in the peloid therapy group compared to the control group. At the 1st month after the end of treatment, hand grip strength, VAS, DASH, PRFEQ pain, function, daily activities, and SF-36 physical health scores (all of p < 0.001) were statistically significant in the peloid treatment group compared to the control group. Peloid treatment was found to be more effective than kinesio taping in SF-36 physical health (p = 0.007) and PRFEQ pain (p = 0.003) scores in the 1st month follow-up after treatment. Peloid therapy in addition to exercise seems more effective in chronic lateral epicondylitis. Randomized controlled long-term studies are needed.ClinicalTrials ID: NCT04687943.

Greek physiotherapists' contemporary knowledge and practice for lateral elbow tendinopathy: An online survey

OBJECTIVES

To investigate physiotherapists' current knowledge and practice in the management of patients with lateral elbow tendinopathy, to explore associations between the participants' education and management preferences and to identify potential evidence-to-practice gaps by making comparisons with recent research recommendations.

DESIGN

An on-line cross-sectional survey.

SUBJECTS

Registered physiotherapists working in Greece with previous experience in the management of lateral elbow tendinopathy.

RESULTS

Three hundred and seventy eight responses met the inclusion criteria. Most responders (70.4%-91.5%) use pain provocation tests for the diagnosis of the condition, while a limited proportion uses patient rated outcome measures (6.9%-13%). Supervised exercise is the mainstay of rehabilitation (92.6%), followed by adjunctive research recommended treatment techniques such as manual therapy (72%) and advice (59.5%). Up to 83.6% of participants use adjunctive treatment techniques that are not recommended or without research recommendation (such as electrophysical agents, ice etc.). Physiotherapists with post-graduate education in musculoskeletal physiotherapy are almost three times more likely to choose only research recommended treatment approaches. There is a lack of consensus in an optimal exercise programme (type, volume, duration etc.) in patients with lateral elbow tendinopathy.

CONCLUSION

Despite research recommendations a limited use of patient rated outcome measures in lateral elbow tendinopathy is recorded. Supervised exercise is the first line treatment option for most physiotherapists, although the optimal application is still unclear. A large proportion of physiotherapists apply adjunctive treatment techniques that are either ineffective or poorly researched suggesting a substantial evidence-to-practice gap. Better access to knowledge, organisational and peer-support can potentially help to bridge this gap.

Effective assessments to identify overuse injuries in unaffected limbs of persons with unilateral upper limb amputations

STUDY DESIGN

Cross-sectional study.

INTRODUCTION

Overuse injuries (OI) present major health problems and oftentimes, permanent disability. Persons with unilateral upper limb diagnoses, such as amputation, are at-risk for developing OI in their unaffected limbs. Measures to identify high-risk populations are needed.

PURPOSE OF THE STUDY

Scores on 6 OI-assessments were compared for persons with unilateral upper limb amputations (UULA) and healthy participants. Cutoff values were proposed.

METHODS

Sixty-two persons with UULA and 62 healthy controls completed this study. Scores for hand volume (HV), visual analogue scale (VAS), multi-site Semmes Weinstein Monofilament for median and ulnar nerves (SWM-M/SWM-U), torque range of motion for wrist/finger extension and flexion (TROM-E/TROM-F), intrinsic tightness (IT), and differential flexor tendon gliding (DFTG) were collected before and after 15 minutes of repetitive and resistive exercise. When analyzing collected data, descriptive statistics, and ANOVA were used to identify differences between groups. Receiver operating characteristic curves (ROC), area under the curve (AUC), sensitivity, and specificity were calculated to determine acceptable cutoff scores. Cutoff values with significant AUC ≥ 0.60 and sensitivity ≥ 0.80 were accepted.

RESULTS

Statistically significant differences were found between HV by gender in both pre-exercise and post-exercise conditions. Gain scores for whole sample HV, female HV, and TROM-E were statistically different although differences were small and not meaningful. Significant AUC and acceptable pre-exercise cutoff values included 375 ml. for female HV (sensitivity 89%, specificity 87%), 505 ml. for male HV (sensitivity 81%, specificity 70%), 82 degrees for TROM-E (sensitivity 92%, specificity 71%), and 73 degrees of TROM-F (sensitivity 90%, specificity 89%).

CONCLUSIONS

Potential at-risk OI-related populations, especially unaffected limbs of UULA persons, are best identified by pre-exercise cutoff values using HV by gender, TROM, and single-site SWM 2.83.

Efficacy of Nonoperative Treatments for Lateral Epicondylitis: A Systematic Review and Meta-Analysis

BACKGROUND

Lateral epicondylitis is a common overuse injury affecting approximately 1 to 3 percent of the population. Although symptoms may disappear spontaneously within 1 year, the clinical guidelines for conservative treatment are not clear. The authors' objective was to examine the outcomes of nonsurgical treatments for lateral epicondylitis through a meta-analysis and provide a treatment recommendation using the available evidence.

METHODS

The authors searched the PubMed, EMBASE, Scopus, and Web of Science databases to identify primary research articles studying conservative treatments (electrophysiotherapy, physical therapy, and injections) for lateral epicondylitis. The authors included randomized controlled trials published in peer-reviewed journals. Data related to outcomes (pain, grip strength, Patient-Rated Tennis Elbow Evaluation score, and Disabilities of the Arm, Shoulder and Hand score) and complications were extracted.

RESULTS

Fifty-eight randomized controlled trials were included in the meta-analysis. Electrophysiotherapy was effective in improving pain [mean difference, -10.0 (95 percent CI, -13.8 to -6.1)], Patient-Rated Tennis Elbow Evaluation score [mean difference, -10.7 (95 percent CI, -16.3 to -5.0)], and Disabilities of the Arm, Shoulder and Hand score [mean difference, -11.9 (95 percent CI, -15.8 to -7.9)]; and physical therapy improved pain [mean difference, -6.0 (95 percent CI, -9.7 to -2.3)] and Patient-Rated Tennis Elbow Evaluation scores [mean difference, -7.5 (95 percent CI, -11.8 to -3.2)] compared to placebo. Injections did not improve any outcome measures. Patients who received electrophysiotherapy and injections reported higher adverse effects than physical therapy patients.

CONCLUSIONS

Patients who received electrophysiotherapy and physical therapy reported statistically and clinically improved scores in pain and function compared to placebo. Injections may put patients at higher risk for adverse effects compared to other conservative treatments. When managing lateral epicondylitis conservatively, electrophysiotherapy and physical therapy should be prioritized before other interventions.

Epicondylopathia humeri radialis

BACKGROUND

Lateral epicondylitis is a common orthopaedic condition often massively restricting the quality of life of the affected patients. There are a wide variety of treatment options - with varying levels of evidence.

METHOD

The following statements and recommendations are based on the current German S2k guideline Epicondylopathia radialis humeri (AWMF registry number: 033 - 2019). All major German specialist societies participated in this guideline, which is based on a systematic review of the literature and a structured consensus-building process.

OUTCOMES

Lateral epicondylitis should be diagnosed clinically and can be confirmed by imaging modalities. The Guidelines Commission issues recommendations on clinical and radiological diagnostic workup. The clinical condition results from the accumulated effect of mechanical overload, neurologic irritation and metabolic changes. Differentiating between acute and chronic disorder is helpful. Prognosis of non-surgical regimens is favourable in most cases. Most cases spontaneously resolve within 12 months. In case of unsuccessful attempted non-surgical management for at least six months, surgery may be considered as an alternative, if there is a corresponding structural morphology and clinical manifestation. At present, it is not possible to recommend a specific surgical procedure.

CONCLUSION

This paper provides a summary of the guideline with extracts of the recommendations and statements of its authors regarding the pathogenesis, prevention, diagnostic workup as well as non-surgical and surgical management.

Management of Achilles and patellar tendinopathy: what we know, what we can do

Tendinopathies are challenging conditions frequent in athletes and in middle-aged overweight patients with no history of increased physical activity. The term “tendinopathy” refers to a clinical condition characterised by pain, swelling, and functional limitations of tendons and nearby structures, the effect of chronic failure of healing response. Tendinopathies give rise to significant morbidity, and, at present, only limited scientifically proven management modalities exist. Achilles and patellar tendons are among the most vulnerable tendons, and among the most frequent lower extremity overuse injuries. Achilles and patellar tendinopathies can be managed primarily conservatively, obtaining good results and clinical outcomes, but, when this approach fails, surgery should be considered. Several surgical procedures have been described for both conditions, and, if performed well, they lead to a relatively high rate of success with few complications. The purpose of this narrative review is to critically examine the recent available scientific literature to provide evidence-based opinions on these two common and troublesome conditions.

Shoulder and scapula muscle training plus conventional physiotherapy versus conventional physiotherapy only: a randomized controlled trial of patients with lateral elbow tendinopathy

BACKGROUND

Previous studies have suggested that weakening of shoulder and scapula muscles have been associated with increased pain, and decreased functional abilities in patients with lateral elbow tendinopathy (LET).

PURPOSE

To compare the effects of shoulder and scapula muscle training plus conventional physiotherapy with conventional physiotherapy only.

METHODS

A group of 48 patients with LET was randomly allocated into two groups: shoulder and scapula muscle training plus conventional physiotherapy (n = 24), and conventional physiotherapy (n = 24). All patients received 12 sessions of treatment for 4 weeks. Furthermore, both groups were instructed to continue their own exercise program at home until four months after the end of treatment. Pain intensity, grip strength, and functional status were measured preintervention, postintervention, and 4 months after the end of intervention (4-month follow-up).

RESULTS

The shoulder and scapula muscle training plus conventional physiotherapy group showed significantly more reduction in pain and greater improvement in functional status compared with conventional physiotherapy group, but there was no significant difference in pain-free grip strength for two groups.

CONCLUSION

Conventional physiotherapy combined with shoulder and scapula muscle training could be more effective in improving the pain and functional abilities of patients with LET compared with conventional physiotherapy only.

Tennis elbow: A clinical review article

Lateral epicondylitis, or tennis elbow is a common condition that presents with pain and tenderness around the common extensor origin of the elbow. Tennis elbow is estimated to affect 1-3% of the adult population each year and is more common in the dominant arm. It is generally regarded as an overuse injury involving repeated wrist extension against resistance, although it can occur as an acute injury (trauma to the lateral elbow). Up to 50% of all tennis players develop symptoms due to various factors including poor swing technique the use of heavy racquet. It's also seen in labourers who utilise heavy tools or engage in repetitive gripping or lifting task. In this article, we discuss the existing literature in the field and the current thinking on optimum treatment modalities. We have reviewed the literature available on med line and have discussed the condition with our specialist colleagues in the field.

Achilles Tendinopathy

Achilles tendinopathy is a common cause of disability. Despite the economic and social relevance of the problem, the causes and mechanisms of Achilles tendinopathy remain unclear. Tendon vascularity, gastrocnemius-soleus dysfunction, age, sex, body weight and height, pes cavus, and lateral ankle instability are considered common intrinsic factors. The essence of Achilles tendinopathy is a failed healing response, with haphazard proliferation of tenocytes, some evidence of degeneration in tendon cells and disruption of collagen fibers, and subsequent increase in noncollagenous matrix. Tendinopathic tendons have an increased rate of matrix remodeling, leading to a mechanically less stable tendon which is more susceptible to damage. The diagnosis of Achilles tendinopathy is mainly based on a careful history and detailed clinical examination. The latter remains the best diagnostic tool. Over the past few years, various new therapeutic options have been proposed for the management of Achilles tendinopathy. Despite the morbidity associated with Achilles tendinopathy, many of the therapeutic options described and in common use are far from scientifically based. New minimally invasive techniques of stripping of neovessels from the Kager's triangle of the tendo Achillis have been described, and seem to allow faster recovery and accelerated return to sports, rather than open surgery. A genetic component has been implicated in tendinopathies of the Achilles tendon, but these studies are still at their infancy.

Does Kinesiotaping improve pain and functionality in patients with newly diagnosed lateral epicondylitis?

PURPOSE

This study aimed to compare the short-term effects of kinesiotaping and extracorporeal shock wave therapy (ESWT) along with physiotherapy on pain, functionality, and grip strength in patients with newly diagnosed lateral epicondylitis undergoing rehabilitation.

METHODS

Forty-five voluntary patients (mean age 48 years) were randomly assigned to three groups. Patients in all groups received physiotherapy consisting of a cold pack and transcutaneous electrical nerve stimulation five times per week for a total of 15 sessions and a home exercise programme including stretching and eccentric strength exercises. In the second group, patients received kinesiotaping 5 days a week for 3 weeks. In the third group, ESWT was applied three times for 3 weeks. Patients were assessed by visual analogue scale for pain intensity, pain-free grip strength using a hand dynamometer, Cyriax Resisted Muscle Test, and Patient-Rated Tennis Elbow Evaluation Scale. All measurements were collected at baseline and after treatment.

RESULTS

There were no significant differences in the demographic characteristics of the patients in all groups at baseline. Intra-group analysis revealed that pain intensity decreased, whereas maximum grip strength and functionality increased in all groups at the end of the treatment (p < 0.05). Inter-group analysis revealed that the kinesiotaping group yielded better results in decreasing pain intensity than the other groups (p < 0.05). The kinesiotaping group (p < 0.001) and ESWT group (p = 0.002) yielded better results in improving functionality than the physiotherapy group. There were significant differences in recovering pain-free grip strength in the kinesiotaping group (p < 0.05).

CONCLUSION

Kinesiotaping was found to be effective for decreasing pain intensity, recovering grip strength, and improving functionality in patients with lateral epicondylitis undergoing rehabilitation.

Management of Chronic Lateral Epicondylitis With Manual Therapy and Local Cryostimulation: A Pilot Study

Objective

The purpose of this pilot study was to evaluate the feasibility and efficacy of adding cryostimulation to manual therapy in patients with chronic lateral epicondylitis.

Methods

The control group (n = 19) was treated with manual therapy consisting of soft-tissue therapy and radial head mobilizations. The experimental group (n = 18) received cryostimulation in addition to manual therapy care similar to that for the control group. Both protocols consisted of 8 treatments over a 4-week period. Outcome measures included pain intensity (visual analog scale), pain-free grip strength (handheld dynamometer), and functional index (Patient-Rated Tennis Elbow Evaluation questionnaire). Assessments were performed at baseline, postintervention, and 3-month follow-up. Adherence and dropout rates were also considered.

Results

Both groups exhibited significant improvements in pain intensity and functional index at postintervention assessments, which were maintained at follow-up. All participants attended the prescribed number of treatments, but 27% were lost at follow-up. Minor adverse events were reported after cryostimulation in 4 cases.

Conclusions

This study indicated that it is feasible to complete a clinical trial evaluating the efficacy of adding cryostimulation to manual therapy in patients with chronic lateral epicondylitis. On the basis of these preliminary data, the combination of cryostimulation and manual therapy care did not provide any additional benefits in both the short term and the long term. Manual myofascial point treatment and mobilization techniques yielded positive outcomes in chronic lateral epicondylitis. Further studies should focus on the sole therapeutic effect of cryostimulation in both patients with acute and those with chronic conditions.

[Tendinopathies of the shoulder and elbow]

BACKGROUND

Tendinopathies of the shoulder and elbow joint are a common problem. According to the current state of knowledge tendinopathies can be separated into acute and chronic tendinitis as well as degenerative tendinosis.

ORIGIN

The causes of tendinopathy can be intrinsic, extrinsic or a combination of both. A false straining or overuse with repetitive microtrauma is often the cause. Particularly affected are tendons of the rotator cuff, the long biceps tendons and lower arm extensors.

TREATMENT

Priority is given to conservative appproaches for these disease processes. Following appropriate diagnostics the pain can be reduced and function can be improved by specific training. When conservative treatment is unsuccessful and in the presence of certain indications, a surgical approach should be considered. In these cases a structural damage of the tendon often already exists, which could have resulted from the tendinopathy. The structural damage must be considered as a separate entity and differentiated from the tendinopathy.

Comparison of effects of eccentric training, eccentric-concentric training, and eccentric-concentric training combined with isometric contraction in the treatment of lateral elbow tendinopathy

STUDY DESIGN

RCT.

INTRODUCTION

Lateral elbow tendinopathy is a common clinical condition. eccentric exercises. eccentric-concentric loading and, isometric exercises are indicated to reduce and manage tendon pain.

PURPOSE OF THE STUDY

To compare the effectiveness of eccentric training, eccentric-concentric training, and eccentric-concentric training combined with isometric contraction in the treatment of lateral elbow tendinopathy.

METHODS

A randomized clinical trial was carried out in a rheumatology and rehabilitation center. A group of 34 patients with later elbow tendinopathy was randomly allocated to Group A (n = 11) who underwent eccentric training, Group B had eccentric-concentric and Group C who had eccentric-concentric and isometric training. All patients received 5 treatments per week for 4 weeks. Pain was evaluated using a visual analog scale and function using a visual analog scale and pain-free grip strength at the end of the 4-week course of treatment (week 4) and 1 month (week 8) after the end of treatment.

RESULTS

The eccentric-concentric training combined with isomentric contractions produced the largest effect in the reduction of pain and improvement of function at the end of the treatment (P < .05) and at any of the follow-up time points (P < .05).

CONCLUSION

The eccentric-concentric training combined with isomentric contractions was the most effective treatment. Future well-designed studies are needed to confirm the results of the present trial.

Achilles Tendinopathy: Current Concepts about the Basic Science and Clinical Treatments

Achilles tendinopathy is one of the most frequently ankle and foot overuse injuries, which is a clinical syndrome characterized by the combination of pain, swelling, and impaired performance. The two main categories of Achilles tendinopathy are classified according to anatomical location and broadly include insertional and noninsertional tendinopathy. The etiology of Achilles tendinopathy is multifactorial including both intrinsic and extrinsic factors. Failed healing response and degenerative changes were found in the tendon. The failed healing response includes three different and continuous stages (reactive tendinopathy, tendon disrepair, and degenerative tendinopathy). The histological studies have demonstrated an increased number of tenocytes and concentration of glycosaminoglycans in the ground substance, disorganization and fragmentation of the collagen, and neovascularization. There are variable conservative and surgical treatment options for Achilles tendinopathy. However, there has not been a gold standard of these treatments because of the controversial clinical results between various studies. In the future, new level I researches will be needed to prove the effect of these treatment options.

Astym treatment vs. eccentric exercise for lateral elbow tendinopathy: a randomized controlled clinical trial

Introduction. Patients with chronic lateral elbow (LE) tendinopathy, commonly known as tennis elbow, often experience prolonged symptoms and frequent relapses. Astym treatment, evidenced in animal studies to promote the healing and regeneration of soft tissues, is hypothesized to improve outcomes in LE tendinopathy patients. This study had two objectives: (1) to compare the efficacy of Astym treatment to an evidence-based eccentric exercise program (EE) for patients with chronic LE tendinopathy, and (2) to quantify outcomes of subjects non-responsive to EE who were subsequently treated with Astym treatment.

Study Design. Prospective, two group, parallel, randomized controlled trial completed at a large orthopedic center in Indiana. Inclusion criteria: age range of 18–65 years old, with clinical indications of LE tendinopathy greater than 12 weeks, with no recent corticosteriod injection or disease altering comorbidities.

Methods. Subjects with chronic LE tendinopathy (107 subjects with 113 affected elbows) were randomly assigned using computer-generated random number tables to 4 weeks of Astym treatment (57 elbows) or EE treatment (56 elbows). Data collected at baseline, 4, 8, 12 weeks, 6 and 12 months. Primary outcome measure: DASH; secondary outcome measures: pain with activity, maximum grip strength and function. The treating physicians and the rater were blinded; subjects and treating clinicians could not be blinded due to the nature of the treatments.

Results. Resolution response rates were 78.3% for the Astym group and 40.9% for the EE group. Astym subjects showed greater gains in DASH scores (p = 0.047) and in maximum grip strength (p = 0.008) than EE subjects. Astym therapy also resolved 20/21 (95.7%) of the EE non-responders, who showed improvements in DASH scores (p < 0.005), pain with activity (p = 0.002), and function (p = 0.004) following Astym treatment. Gains continued at 6 and 12 months. No adverse effects were reported.

Conclusion. This study suggests Astym therapy is an effective treatment option for patients with LE tendinopathy, as an initial treatment, and after an eccentric exercise program has failed.

Registration/Funding. Ball Memorial Hospital provided limited funding. Trial registration was not required by FDAAA 801.

Known about the Subject. Under the new paradigm of degenerative tendinopathy, eccentric exercise (EE) is emerging as a first line conservative treatment for LE tendinopathy. EE and Astym treatment are among the few treatment options aiming to improve the degenerative pathophysiology of the tendon. In this trial, Astym therapy, which has shown success in the treatment of tendinopathy, is compared to EE, which has also shown success in the treatment of tendinopathy.

Clinical Relevance. There is a need for more effective, conservative treatment options. Based on the current efficacy study, Astym therapy appears to be a promising, non-invasive treatment option.

Tratamento fisioterapêutico para epicondilite lateral: uma revisão sistemática

INTRODUÇÃO: Embora o tratamento conservador ainda seja a melhor conduta inicial para a epicondilite lateral do cotovelo, há pouca evidência científica de que o tratamento fisioterapêutico altere o curso natural da doença e seja efetiva no tratamento dessa patologia. OBJETIVO: Avaliar a efetividade e a segurança das diversas intervenções fisioterapêuticas utilizadas no tratamento conservador da epicondilite lateral. MATERIAIS E MÉTODOS: Foram incluídos apenas ensaios clínicos aleatorizados e quase aleatorizados que utilizaram pelo menos uma modalidade fisioterapêutica como uma das intervenções. Foi realizada uma busca nas bases de dados eletrônicos MEDLINE; Embase; LILACS e SciELO até dezembro de 2010. Não houve restrição do período de publicação dos artigos. Com o objetivo de aumentar a sensibilidade e a precisão, a estratégia de busca utilizada foi adaptada para cada base de dados. Foi utilizada a pontuação da escala PEDro para avaliação da qualidade metodológica dos ensaios clínicos aleatorizados. RESULTADOS: 26 artigos foram incluídos na revisão sistemática e a avaliação da maioria desses artigos apresentou qualidade metodológica satisfatória (6,4 pontos). Em relação aos aspectos mensurados, todos os artigos avaliaram a dor, 18 (69%) examinaram a força de preensão e 11 (42%) a função dos pacientes. Quanto à duração do acompanhamento dos pacientes apenas nove (35%) artigos realizaram acompanhamento a longo prazo. CONCLUSÃO: A melhor opção para o tratamento da epicondilite lateral parece ser a combinação de modalidades terapêuticas, o que condiz com a realidade clínica do fisioterapeuta. Porém, mais ensaios clínicos com boa qualidade metodológica são necessários para determinar a efetividade da maioria das modalidades terapêuticas encontradas.

Effects of taping on pain, grip strength and wrist extension force in patients with tennis elbow

Background

Tennis elbow (TE) is a common musculotendinous degenerative disorder of the extensor origin at the lateral humeral epicondyle. Different modes of treatment are used for management of tennis elbow.

Objectives

This study investigated the effect of the taping technique (TT) on pain, grip strength and wrist extension force in treatment of tennis elbow.

Patients and Methods

Thirty patients (16 men /14 women with a mean age of 32.2 years) with tennis elbow of their dominant arm participated in this study. Outcome measures were assessment of pain at the lateral aspect of the elbow, grip strength and wrist extension force before and five to ten minutes after application of elbow tape on the affected and unaffected arms. A Visual Analog Scale was used to assess pain. A dynamometer and a hand-held dynamometer were used for evaluation of grip strength and wrist extension force, respectively.

Results

Among the variables, significant differences were found in wrist extension forces between effected and unaffected arms (P = 0.02). Changes in grip strength showed statically significant improvements in the affected arm compared to the unaffected arm (P = 0.03). Also, in assessment of pain at the lateral epicondyle, the mean change between affected and unaffected arms was significant, with P = 0.001.

Conclusions

The taping technique, as applied in this study demonstrates an impressive effect on wrist extension force and grip strength of patients with TE. Elbow taping also reduces pain at the lateral aspect of the elbow in these patients.

Is eccentric exercise an effective treatment for lateral epicondylitis? A systematic review

OBJECTIVE

To establish the effectiveness of eccentric exercise as a treatment intervention for lateral epicondylitis.

DATA SOURCES

ProQuest, Medline via EBSCO, AMED, Scopus, Web of Science, CINAHL.

REVIEW METHODS

A systematic review was undertaken to identify randomized and controlled clinical trials incorporating eccentric exercise as a treatment for patients diagnosed with lateral epicondylitis. Studies were included if: they incorporated eccentric exercise, either in isolation or as part of a multimodal treatment protocol; they assessed at least one functional or disability outcome measure; and the patients had undergone diagnostic testing. The methodological quality of each study was assessed using the Modified Cochrane Musculoskeletal Injuries Group score sheet.

RESULTS

Twelve studies met the inclusion criteria. Three were deemed 'high' quality, seven were 'medium' quality, and two were 'low' quality. Eight of the studies were randomized trials investigating a total of 334 subjects. Following treatment, all groups inclusive of eccentric exercise reported decreased pain and improved function and grip strength from baseline. Seven studies reported improvements in pain, function, and/or grip strength for therapy treatments inclusive of eccentric exercise when compared with those excluding eccentric exercise. Only one low-quality study investigated the isolated effects of eccentric exercise for treating lateral epicondylitis and found no significant improvements in pain when compared with other treatments.

CONCLUSION

The majority of consistent findings support the inclusion of eccentric exercise as part of a multimodal therapy programme for improved outcomes in patients with lateral epicondylitis.

Comparing two eccentric exercise programmes for the management of Achilles tendinopathy. A pilot trial

OBJECTIVE

To compare eccentric and static exercises as proposed by Stanish with eccentric exercises as proposed by Alfredson in the management of Achilles tendinopathy.

METHODS

Patients with midportion Achilles tendinopathy for at least 3 months were included in this trial. They were sequentially allocated to receive either Stanish's exercise programme or Alfredson's exercise programme. Outcome measures were pain and function using the VISA-A score. Patients were evaluated at baseline, at the end of treatment (week 12), and 6 months (week 36) after the end of treatment.

RESULTS

41 patients met the inclusion criteria. At the end of treatment, there was a rise in VISA-A score in both groups compared with baseline (p < 0.05, paired t-test). There were significant differences in the VISA-A score between the groups at the end of treatment and at the 6-month follow up; Alfredson exercise programme group produced the largest effect (p < 0.0005, independent t-test).

CONCLUSION

An exercise programme based on Alfredson protocol was superior to Stanish model to reduce pain and improve function in patients with Achilles tendinopathy at the end of the treatment and at the follow-up. Further research is needed to confirm our results.

Two cases of work-related lateral epicondylopathy treated with Graston Technique® and conservative rehabilitation

OBJECTIVE

To chronicle the conservative treatment and management of two work-related cases of lateral elbow pain diagnosed as lateral epicondylopathy.

CLINICAL FEATURES

PATIENT 1: A 48-year old female presented with gradual onset of right lateral elbow pain over the course of six weeks related to work activities of repetitive flexion/extension movements of the wrist and finger keying. PATIENT 2: A 47-year old female presented with gradual onset of left lateral elbow pain over the course of four weeks related to work activities of repetitive squeezing and gripping.

INTERVENTION AND OUTCOME

The conservative treatment approach consisted of activity modification, bracing, medical acupuncture with electrical stimulation, Graston Technique®, and rehabilitative exercise prescription. Outcome measures included verbal pain rating scale (VPRS), QuickDASH Work Module Score (QDWMS), and a return to regular work activities. Both patients attained resolution of their complaints, and at eight month follow-up reported no recurrence of symptoms.

CONCLUSION

A combination of conservative rehabilitation strategies may be used by chiropractors to treat work-related lateral epicondylopathy and allow for individuals to minimize lost time related to this condition.

Effectiveness of different methods of resistance exercises in lateral epicondylosis--a systematic review

STUDY DESIGN

Systematic Review.

INTRODUCTION

Lateral epicondylosis (LE) is relatively common with an annual incidence in the general population of 1% to 3%. Systematic reviews have identified exercise is effective, but have not established specific exercise parameters.

PURPOSE

The purpose of this systematic review was to synthesize the quality and content of clinical research addressing type and dosage of resistance exercises in lateral epicondylosis.

METHODS

Computerized bibliographic databases (1990-2010) were searched using relevant keywords; bibliographies of included papers were hand searched. Of 594 screened abstracts, 11 articles (12 studies) met inclusion criteria. Articles were randomly allocated to pairs of reviewers who independently verified data extraction and appraised the full text, using a structured critical appraisal tool with 24 items. Data extraction was limited by a lack of consistent reporting of elements of exercise dosage.

RESULTS

The mean quality rating of the studies was 72%, with 2 papers exceeding 75% quality. Of the 12 studies, 9 addressed the effects of isotonic (eccentric/concentric) exercises, 2 studied the effect of isometric and one studied isokinetic exercises. The exercise programs ranged over a period of 4 to 52 weeks. Exercises were prescribed 1 to 6 times per day, with an average duration of 15 minutes per session, and average of 15 repetitions (range: 3 to 50), with 1 to 4 sets per session.

CONCLUSION

All the studies reported that resistance exercise resulted in substantial improvement in pain and grip strength; eccentric exercise was most studied. Strengthening using resistance exercises is effective in reducing pain and improving function for lateral epicondylosis but optimal dosing is not defined.

Comparing the effects of eccentric training with eccentric training and static stretching exercises in the treatment of patellar tendinopathy. A controlled clinical trial

OBJECTIVE

The aim of the present study was to investigate the effectiveness of eccentric training and eccentric training with static stretching exercises in the management of patellar tendinopathy.

DESIGN

Controlled clinical trial.

SETTING

Rheumatology and rehabilitation centre.

SUBJECTS

Forty-three patients who had patellar tendinopathy for at least three months. They were allocated to two groups by alternative allocation.

INTERVENTIONS

Group A (n = 22) was treated with eccentric training of patellar tendon and static stretching exercises of quadriceps and hamstrings and Group B (n = 21) received eccentric training of patellar tendon. All patients received five treatments per week for four weeks.

OUTCOMES

Pain and function were evaluated using the VISA-P score at baseline, at the end of treatment (week 4), and six months (week 24) after the end of treatment.

RESULTS

At the end of treatment, there was a rise in VISA-P score in both groups compared with baseline (P<0.0005, paired t test). There were significant differences in the VISA-P score between the groups at the end of treatment (+14; 10 to 18) and at the six-month follow-up (+19; 13 to 24); eccentric training and static stretching exercises produced the largest effect (P<0.0005, one-way ANOVA).

CONCLUSIONS

Eccentric training and static stretching exercises is superior to eccentric training alone to reduce pain and improve function in patients with patellar tendinopathy at the end of the treatment and at follow-up.

Proximal wrist extensor tendinopathy

Proximal wrist extensor tendinopathy, which is also known as tennis elbow, is pain at or just distal to the lateral humeral epicondyle within the proximal wrist extensor tendon. It occurs commonly in certain athletes but can also occur in people with jobs that require repetitive movements of the hand and upper limb. In most cases the tendon involved shows no signs of inflammation or tendonitis, but instead shows fibroblasts, vascular hyperplasia, and disorganized collagen. Diagnosis is often made by history and physical exam alone. Most people respond to conservative measures including activity modification, analgesics, manipulation of tissue, and exercise. In some cases, an injection of corticosteroid or botulinum toxin may be used. Surgery is rarely needed.

Comparison of effects of a home exercise programme and a supervised exercise programme for the management of lateral elbow tendinopathy

BACKGROUND

Home and supervised exercise programmes consisting of stretching and eccentric exercises have been recommended for the management of lateral elbow tendinopathy (LET). No studies have examined their comparative efficacy effectiveness.

OBJECTIVE

In this study, whether a home exercise programme is more successful than a supervised exercise programme in treating patients with LET was investigated.

METHODS

Patients with unilateral LET for at least 4 weeks were included in this trial. They were sequentially allocated to receive either a home exercise programme or a supervised exercise programme five times a week for 12 weeks. The exercise programme consisted of slow progressive eccentric exercises of wrist extensors and static stretching of the extensor carpi radialis brevis tendon. Outcome measures were pain, using a visual analogue scale, and function, using a visual analogue scale and the pain-free grip strength. Patients were evaluated at baseline, at the end of treatment (week 12), and 3 months (week 24) after the end of treatment.

RESULTS

70 patients met the inclusion criteria. At the end of treatment, there was a decline in pain and a rise in function in both groups compared with baseline (p<0.0005, paired t test). There were significant differences in the reduction of pain and the improvement of function between the groups at the end of treatment and at the 3-month follow up; the supervised exercise programme produced the largest effect (p<0.0005, independent t test).

CONCLUSIONS

Supervised exercise programme is superior to home exercise programme to reduce pain and improve function in patients with LET at the end of the treatment and at the follow-up. Further research is needed to confirm our results.

Examining the degree of pain reduction using a multielement exercise model with a conventional training shoe versus an ultraflexible training shoe for treating plantar fasciitis

Plantar fasciitis is a common injury to the plantar aponeurosis, manifesting as pain surrounding its proximal insertion at the medial calcaneal tubercle. Pain is typically worse in the morning when getting out of bed, and may subside after the tissue is sufficiently warmed up. For running-based athletes and individuals who spend prolonged periods of time on their feet at work, plantar fasciitis may become recalcitrant to conservative treatments such as ice, rest, and anti-inflammatory medication. Exercise-based therapies have received only limited attention in the literature for this common problem, yet they are becoming increasingly validated for pain relief and positive tissue remodeling at other sites of similar soft-tissue overuse injury. This study reports on pain outcomes in individuals experiencing chronic plantar fasciitis while wearing a shoe with an ultraflexible midsole (Nike Free 5.0) (FREE) versus a conventional training (CON) shoe in a 12-week multielement exercise regimen, and after a 6-month follow-up. Adults with >or= 6-month history of painful heel pain were recruited and randomly assigned to wear 1 of the 2 shoes. All subjects completed the same exercise protocol. A visual analogue scale item tracked peak pain in the preceding 24 hours taken at baseline, 6- and 12-week points, and at the 6-month follow-up. Twenty-one subjects completed the program (9 FREE; 12 CON). Both groups reported significant improvements in pain by the 6-month follow-up, and the FREE group reported an overall reduced level of pain throughout the study as a result of lower mean pain scores at the midpoint and post-test compared with the CON group. The exercise regimen employed in this study appears to reduce pain associated with chronic plantar fasciitis, and in doing so, the Nike 5.0 shoe may result in reductions in pain earlier than conventional running shoes.

Comparing the effects of exercise program and low-level laser therapy with exercise program and polarized polychromatic non-coherent light (bioptron light) on the treatment of lateral elbow tendinopathy

BACKGROUND DATA

The use of low-level laser therapy (LLLT) and polarized polychromatic non-coherent light as supplements to an exercise program has been recommended for the management of lateral elbow tendinopathy (LET).

OBJECTIVE

To investigate whether an exercise program supplemented with LLLT is more successful than an exercise program supplemented with polarized polychromatic non-coherent light in treating LET.

MATERIALS AND METHODS

Patients with unilateral LET for at least 4 wk were sequentially allocated to receive either an exercise program with LLLT or an exercise program with polarized polychromatic non-coherent light. The exercise program consisted of eccentric and static stretching exercises of wrist extensors. In the LLLT group a 904-nm Ga-As laser was used in continuous mode, and the power density was 130 mW/cm(2), and the dose was 0.585 J/point. In the group receiving polarized polychromatic non-coherent light the Bioptron 2 was used to administer the dose perpendicularly to the lateral epicondyle at three points at an operating distance of 5-10 cm for 6 min at each position. The outcome measures were pain and function and were evaluated at baseline, at the end of the treatment (week 4), and 3 mo after the end of treatment (week 16).

RESULTS

Fifty patients met the inclusion criteria. At the end of treatment there was a decline in pain and a rise in function in both groups compared with baseline (p < 0.0005 on the paired t-test). There were no significant differences in the reduction of pain and the improvement of function between the groups at the end of treatment and at the 3-mo follow-up (p > 0.0005 on the independent t-test).

CONCLUSIONS

The results suggest that the combination of an exercise program with LLLT or polarized polychromatic non-coherent light is an adequate treatment for patients with LET. Further research to establish the relative and absolute effectiveness of such a treatment approach is needed.

Eccentric loading compared with shock wave treatment for chronic insertional achilles tendinopathy. A randomized, controlled trial

BACKGROUND

Nonoperative management of chronic tendinopathy of the Achilles tendon insertion has been poorly studied. With the recently demonstrated effectiveness of eccentric loading and of repetitive low-energy shock wave therapy in patients with midsubstance Achilles tendinopathy, the aim of the present randomized, controlled trial was to verify the effectiveness of both procedures exclusively in patients with insertional Achilles tendinopathy.

METHODS

Fifty patients with chronic (six months or more) recalcitrant insertional Achilles tendinopathy were enrolled in a randomized, controlled study. All patients had received treatment, including local injections of an anesthetic and/or corticosteroids, a prescription of nonsteroidal anti-inflammatory drugs, and physiotherapy, without success for at least three months. A computerized random-number generator was used to draw up an allocation schedule. Twenty-five patients were allocated to receive eccentric loading (Group 1), and twenty-five patients were allocated to treatment with repetitive low-energy shock wave therapy (Group 2). Analysis was on an intention-to-treat basis. Primary follow-up was at four months, and afterward patients were allowed to cross over. The last follow-up evaluation was at one year after completion of the initial treatment. The patients were assessed for pain, function, and activity with use of a validated questionnaire (the Victorian Institute of Sport Assessment-Achilles [VISA-A] questionnaire).

RESULTS

At four months from baseline, the mean VISA-A score had increased in both groups, from 53 to 63 points in Group 1 and from 53 to 80 points in Group 2. The mean pain rating decreased from 7 to 5 points in Group 1 and from 7 to 3 points in Group 2. Seven patients (28%) in Group 1 and sixteen patients (64%) in Group 2 reported that they were completely recovered or much improved. For all outcome measures, the group that received shock wave therapy showed significantly more favorable results than the group treated with eccentric loading (p = 0.002 through p = 0.04). At four months, eighteen of the twenty-five patients from Group I had opted to cross over, as did eight of the twenty-five patients from Group 2. The favorable results after shock wave therapy at four months were stable at the one-year follow-up evaluation.

CONCLUSIONS

Eccentric loading as applied in the present study showed inferior results to low-energy shock wave therapy as applied in patients with chronic recalcitrant tendinopathy of the insertion of the Achilles tendon at four months of follow-up. Further research is warranted to better define the indications for this treatment modality.

Effects of low-level laser and plyometric exercises in the treatment of lateral epicondylitis

OBJECTIVE

This study was undertaken to compare the effectiveness of a protocol of combination of laser with plyometric exercises and a protocol of placebo laser with the same program, in the treatment of tennis elbow.

BACKGROUND DATA

The use of low-level laser has been recommended for the management of tennis elbow with contradictory results. Also, plyometric exercises was recommended for the treatment of the tendinopathy.

METHODS

Fifty patients who had tennis elbow participated in the study and were randomised into two groups. Group A (n = 25) was treated with a 904 Ga-As laser CW, frequency 50 Hz, intensity 40 mW and energy density 2.4 J/cm(2), plus plyometric exercises and group B (n = 25) that received placebo laser plus the same plyometric exercises. During eight weeks of treatment, the patients of the two groups received 12 sessions of laser or placebo, two sessions per week (weeks 1-4) and one session per week (weeks 5-8). Pain at rest, at palpation on the lateral epicondyle, during resisted wrist extension, middle finger test, and strength testing was evaluated using Visual Analogue Scales. Also it was evaluated the grip strength, the range of motion and weight test. Parameters were determined before the treatment, at the end of the eighth week course of treatment (week 8), and eighth (week 8) after the end of treatment.

RESULTS

Relative to the group B, the group A had (1) a significant decrease of pain at rest at the end of 8 weeks of the treatment (p < 0.005) and at the end of following up period (p < 0.05), (2) a significant decrease in pain at palpation and pain on isometric testing at 8 weeks of treatment (p < 0.05), and at 8 weeks follow-up (p < 0.001), (3) a significant decrease in pain during middle finger test at the end of 8 weeks of treatment (p < 0.01), and at the end of the follow-up period (p < 0.05), (4) a significant decrease of pain during grip strength testing at 8 weeks of treatment (p < 0.05), and at 8 weeks follow-up (p < 0.001), (5) a significant increase in the wrist range of motion at 8 weeks follow-up (p < 0.01), (6) an increase in grip strength at 8 weeks of treatment (p < 0.05) and at 8 weeks follow-up (p < 0.01), and (7) a significant increase in weight-test at 8 weeks of treatment (p < 0.05) and at 8 weeks follow-up (p < 0.005).

CONCLUSION

The results suggested that the combination of laser with plyometric exercises was more effective treatment than placebo laser with the same plyometric exercises at the end of the treatment as well as at the follow-up. Future studies are needed to establish the relative and absolute effectiveness of the above protocol.

Common tendinopathies in the upper and lower extremities

Overuse tendon injuries (tendinopathies) present a challenge to sports medicine patients and clinicians. Despite the high prevalence of tendinopathy in recreational and competitive athletes, treatment is often hampered by contradictory definitions and descriptions of the underlying pathology, with a limited repertoire of evidence-based treatments. This review provides the clinician with a basic overview of tendon structure and pathophysiology, and highlights the most common tendinopathies affecting the upper and lower extremities, including an update on recent advances in conservative management.
