Do joint mobilizations assist in the recovery of lateral elbow tendinopathy? A systematic review and meta-analysis

Percutaneous tendon dry needling and thrust manipulation as an adjunct to multimodal physical therapy in patients with lateral elbow tendinopathy: A multicenter randomized clinical trial

OBJECTIVE

The purpose of this study was to assess the effects of adding electrical dry needling and thrust manipulation into a multimodal program of exercise, mobilization, and ultrasound in patients with lateral elbow tendinopathy.

DESIGN

Randomized, single-blinded, multicenter, parallel-group trial.

SETTING

Thirteen outpatient physical therapy clinics in nine different US states.

PARTICIPANTS

One hundred and forty-three participants (n = 143) with lateral elbow tendinopathy were randomized.

INTERVENTION

Cervical spine manipulation, extremity manipulation, and percutaneous tendon electrical dry needling plus multimodal physical therapy (n = 73) or multimodal physical therapy (n = 70) alone.

MAIN MEASURES

The primary outcome was elbow pain intensity and disability as measured by the Patient-Rated Tennis Elbow Evaluation at baseline, 1 week, 4 weeks, and 3 months. Secondary outcomes included the Numeric Pain Rating Scale, Tennis Elbow Functional Scale, Global Rating of Change, and medication intake.

RESULTS

The 2 × 4 analysis of covariance demonstrated that individuals with lateral elbow tendinopathy receiving electrical dry needling and thrust manipulation plus multimodal physical therapy experienced significantly greater improvements in disability (Patient-Rated Tennis Elbow Evaluation: F = 19.675; P < 0.001), elbow pain intensity (Numeric Pain Rating Scale: F = 22.769; P < 0.001), and function (Tennis Elbow Function Scale: F = 13.269; P < 0.001) than those receiving multimodal physical therapy alone at 3 months. The between-group effect size was large for pain and disability (Patient-Rated Tennis Elbow Evaluation: standardized mean difference = 1.13; 95% confidence interval: 0.78, 1.48) in favor of the electrical dry needling and thrust manipulation group.

CONCLUSIONS

The inclusion of percutaneous tendon electrical dry needling and thrust manipulation into a multimodal program of exercise, mobilization and ultrasound was more effective than multimodal physical therapy alone in individuals with lateral elbow tendinopathy.Trial Registration: www.clinicaltrials.gov NCT03167710 May 30, 2017.

Orthopaedic Manual Physical Therapy: A Modern Definition and Description

Currently, orthopaedic manual physical therapy (OMPT) lacks a description of practice that reflects contemporary thinking and embraces advances across the scientific, clinical, and educational arms of the profession. The absence of a clear definition of OMPT reduces understanding of the approach across health care professions and potentially limits OMPT from inclusion in scientific reviews and clinical practice guidelines. For example, it is often incorrectly classified as passive care or incorrectly contrasted with exercise-therapy approaches. This perspective aims to provide clinicians, researchers, and stakeholders a modern definition of OMPT that improves the understanding of this approach both inside and outside the physical therapist profession. The authors also aim to outline the unique and essential aspects of advanced OMPT training with the corresponding examination and treatment competencies. This definition of practice and illustration of its defining characteristics is necessary to improve the understanding of this approach and to help classify it correctly for study in the scientific literature. This perspective provides a current definition and conceptual model of OMPT, defining the distinguishing characteristics and key elements of this systematic and active patient-centered approach to improve understanding and help classify it correctly for study in the scientific literature.

The efficacy of taping on elbow proprioception in healthy individuals: A single-blinded randomized placebo-controlled study

BACKGROUND

Taping stimulates the mechanoreceptors, increases sensory information to the central nervous system, and improves sensorimotor synchronization, resulting in improved motor control. However, the efficacy of taping on elbow proprioception is not clear.

PURPOSE

This study aimed to evaluate the immediate effects of taping on elbow proprioception in healthy individuals.

STUDY DESIGN

This study was a two-arm, parallel-group, randomized, controlled, single-blinded study with a sham application.

METHODS

Fifty six healthy adults were randomized 1:1 to kinesio taping (n = 27) or sham taping (n = 29). Active joint position sense error (JPSE) was used to quantify proprioception using a universal goniometer at three-time points: baseline (BS), immediately after taping (IA), and 30 minutes after taping (30MA), with the tape still in place at 70° and 110° of elbow flexion. Participants were blinded to group assignments. The Friedman analysis assessed differences between evaluations within groups, and the Mann-Whitney U test determined differences between groups.

RESULTS

The study was completed with 56 participants and there were no dropouts. No skin reaction or adverse effect was observed in the participants and no test trial was excluded. The baseline scores of the groups were similar (p > 0.05). A significant difference was detected in the study group after kinesio taping at 70° (MD = -1.22; CI = (-2.33: -0.10; p < 0.005; d = 0.653) and 110° of elbow flexion (MD = -1.34; CI = 2,47: -0,21; p < 0.005; d = 0.73). This statistically significant difference was observed even at the 30MA evaluations at 70° (p < 0.05). Also, there was a statistically insignificant tendency to decrease in JPSE of both groups at both degrees following taping.

CONCLUSIONS

Elbow proprioception may be enhanced by kinesio taping, and this effect could last up to 30 minutes at 70° of elbow flexion. In contrast, sham taping did not produce such an improvement. Based on the differences in JPSE, kinesio taping proved more effective and had a longer-lasting impact than the sham application. The statistically insignificant tendency to decrease in JPSE may indicate that the 30-minute application period is inadequate to create a statistically significant effect on elbow proprioception. Longer usage periods can better reveal the effects of orthoses on proprioception.

Rehabilitation of the painful elbow

Although lateral elbow pain and medial ulnar collateral ligament injury are common musculoskeletal pathologies in overhead athletes, the evidence supporting specific interventions for managing these conditions is scarce. Management of these conditions has been guided mostly by expert opinion rather than empirical evidence, yet the lack of comparative data in the literature has not negatively affected return-to-play rates following surgery. However, an understanding of what is known regarding unimodal and multimodal treatments for lateral elbow pain and medial ulnar collateral ligament injury is needed for clinicians to select evidence-based treatment pathways and highlight what is not known to develop future high-quality investigations.

Immediate Effects of Mulligan Mobilization on Elbow Proprioception in Healthy Individuals: A Randomized Placebo-Controlled Single-Blind Study

OBJECTIVE

The aim of this study was to investigate the immediate effects of Mulligan's mobilization with movement (MWM) on elbow proprioception.

METHODS

The study included 26 participants in the intervention group and 30 participants in the control group. The intervention group received MWM, while the control group received a sham application. Proprioception was assessed with joint position sense error at baseline, immediately after mobilization, and 30 minutes after mobilization with 70° and 110° of elbow flexion. The hypothesis of interest was the group × time interaction.

RESULTS

At 110° of elbow flexion, group × time interaction was significant (F[2, 108] = 11.48, P = .001). In the paired comparisons, there was a statistically significant difference in favor of the control group in the first measurement (P = .003). No difference was detected in other time points (P = 1.00). At 70° of elbow flexion, there was no significant difference between the time point × group interaction (F[2, 108] = 1.37, P = .10). Therefore, no pairwise comparison was made.

CONCLUSION

In this study of healthy participants, no immediate difference was found between MWM and sham application on elbow proprioception.

A systematic review of the effectiveness of wrist manipulative therapy in patients with lateral epicondylitis

STUDY DESIGN

Systematic review.

INTRODUCTION

Several treatment methods treat lateral epicondylitis, but there is no consensus regarding the most effective method. Research has suggested that joint mobilizations may help recover patients with lateral epicondylitis.

PURPOSE OF THE STUDY

To determine if wrist joint manipulations effectively improve pain, grip strength, ROM, and functional outcome in adults with lateral epicondylitis.

METHODS

Searches were performed in 6 databases to identify relevant clinical trials. Three reviewers independently extracted data and assessed the methodological quality using the PEDro scale. Standard data were extracted and summarized.

RESULTS

A total of 4 studies met the inclusion criteria. A best-evidence synthesis was used to summarize the results. The included studies found effectiveness in favor of wrist manipulations given for at least 3 weeks to reduce pain in lateral epicondylitis against comparison groups comprising ultrasound, laser, friction massage, and exercises. Functional outcomes varied considerably among studies. Grip strength showed varied results, and no effect was seen on wrist ROM.

CONCLUSION

The evidence is convincing that wrist joint manipulations positively affect pain in the short term, compared to comparison groups in the management of lateral epicondylitis. Future high-quality studies are recommended.

[Physiotherapeutic therapy modalities for lateral epicondyopathy]

Physiotherapy interventions can have a positive effect on the symptoms and relief of symptoms of lateral epicondylopathy (LE). However, there is currently no standard physiotherapy protocol for treating LE. Today, a multimodal treatment approach that focuses on progressive exercise therapy is recommended. While in the past, most treatment protocols were based on eccentric training, recent research shows that other forms of training can also improve pain and function in tendinopathies.

Lateral Elbow Pain and Muscle Function Impairments

Although often described as a self-limiting condition and likely to resolve on its own, high recurrence rates and extended sick leave frame a need for effective non-surgical treatment for people with lateral elbow tendinopathy. The interrelationship of histological and structural changes to the tendon, the associated impairments in motor control, and potential changes in pain processing may all drive symptoms. This clinical practice guideline covers the epidemiology, functional anatomy and pathophysiology, risk factors, clinical course, prognosis, differential diagnosis, tests and measures, and interventions for managing lateral elbow tendinopathy in the physical therapy clinic.

Manual therapy should not be on the sideline in the game of treating tendinopathy

Tendinopathy is a common but difficult condition to manage in the orthopedic and sports settings. Despite strong evidence supporting exercise and load-management, a substantial proportion of individuals with the condition do not achieve a satisfactory long-term outcome. Tendinopathy can be associated with a number of impairments, including mobility deficits, muscle performance impairments, pain, and possible altered central pain processing - all of which are indications for manual therapy. Manual therapy has not been well described in the management of tendinopathy, even though its indications match the impairments associated with the condition. In this clinical perspective, the role of manual therapy in the management of tendinopathy is explored, with the intention of expanding possible treatment strategies for this challenging condition.

Treatment, Diagnostic Criteria and Variability of Terminology for Lateral Elbow Pain: Findings from an Overview of Systematic Reviews

Background: Lateral elbow pain (LEP) represents a musculoskeletal disorder affecting the epicondyloid region of the elbow. The terminological framework of this problem in literature, to date, is confusing. This systematic review (SR) aims to analyse the panorama of the scientific literature concerning the pathogenetic framework, treatment, and clinical diagnosis of LEP. Methods: We conducted an SR according to the guidelines of the PRISMA statement. We performed research using the electronic Medline, Epistemonikos, and Cochrane Library databases. The research started on 12 January 2022 and finished on 30 April 2022. We included all systematic reviews and meta-analyses published, in English, between 1989 and 2022. The articles’ selection was based on critical appraisal using Amstar 2. In the selected reviews we obtained the etiopathogenic terminology used to describe the symptoms, treatment, and diagnostic criteria of LEP. Results: Twenty-five SRs met the eligibility criteria and were included in the study. From these SRs, 227 RCT articles were analysed and different treatments proposals were extracted, such as exercise, manipulation corticosteroid injection, and surgery. In the selected articles, 10 different terms emerged to describe LEP and 12 different clinical tests. The most common treatments detected in this SR were a conservative multimodal approach (e.g., eccentric exercises, manual therapy, acupuncture, ultrasound), then surgery or other invasive treatments (e.g., corticosteroid injection, tenotomy). The most common term detected in this SR was “lateral epicondylitis” (n = 95, 51.6%), followed by “tennis elbow” (n = 51, 28.1%) and “lateral epicondylalgia” (n = 18, 9.4%). Among the diagnostic tests were painful palpation (n = 101, 46.8%), the Cozen test (n = 91, 42.1%), the pain-free grip-strength test (n = 41, 19.0%), and the Maudsley test (n = 48, 22.2%). A total of 43.1% of RCTs (n = 96) included subjects with LEP > 3 months, 40.2% (n = 85) included patients with LEP < 3 months, and 16.7% of the items (n = 35) were not specified by the inclusion criteria on the onset of symptoms. Conclusions: In this SR, a considerable terminological heterogeneity emerged in the description of LEP, associated with the lack of clear and recognised diagnostic criteria in evaluating and treating patients with lateral elbow pain.

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.

Effectiveness of eccentric strengthening in the treatment of lateral elbow tendinopathy: A systematic review with meta-analysis

STUDY DESIGN

Meta-analysis.

INTRODUCTION

Lateral elbow tendinopathy is a common condition with an annual incidence of up to 3% of the population. Eccentric strengthening has shown promise as a method to treat lateral elbow tendinopathy, but is unclear if it is superior to other forms of treatment.

PURPOSE OF THE STUDY

The purpose of this study was to investigate the effectiveness of eccentric strengthening compared with other forms of strengthening and pain-relieving modalities on pain, strength, and function in people with lateral elbow tendinopathy.

METHODS

Five electronic databases were searched. Reference lists of selected articles were hand-searched. Outcomes were defined a priori. Meta-analyses were performed using a random effects model with standardized mean differences, test of heterogeneity, and sensitivity analyses.

RESULTS

Eight articles were included in this review. When comparing eccentric strengthening to other forms of strengthening and pain-relieving modalities, there were significant large effect size of 1.12 (CI: 0.31-1.93) and 1.22 (CI: 0.25-2.18) in reducing pain and improving function in the short-term, respectively. In long-term, results were inconclusive on all outcomes.

DISCUSSION

A treatment program using eccentric strengthening of adequate intensity and duration seemed to be most effective for treating lateral elbow tendinopathy.

CONCLUSIONS

The state of science of best care for lateral elbow tendinopathy is still in its infancy. Large, high-quality randomized controlled trials with clearly defined strengthening regime are needed to determine optimal dosage to maximize treatment effects. Recommendations were provided based on careful synthesis of findings from this review and current evidence in literature.

The impact of a hand therapy workplace-based educational approach on the management of lateral elbow tendinopathy: A randomized controlled study

BACKGROUND

Lateral elbow tendinopathy (LET) is one of the most prevalent work-related musculoskeletal conditions. Management strategies for LET rarely consider patients' work environments and have limited focus on education regarding occupational risk factors. Workplace-based rehabilitation has shown benefits in the return to work processes for injured workers with other health conditions, but no studies have investigated the impact of a workplace-based educational approach in the management of LET.

PURPOSES

First, to identify the impact of an additional workplace-based educational intervention to standard hand therapy care on the outcomes of pain, grip strength, and function. Second, to identify the effectiveness of standard hand therapy on the same clinical outcomes.

STUDY DESIGN

A randomized controlled trial.

METHODS

Forty-nine participants were randomized to the control group (n = 25) or intervention group (n == 24). The control group received standard hand therapy for 12 weeks. The intervention group received standard hand therapy for the first 12 weeks plus an additional workplace-based educational intervention, "Working Hands-ED," delivered by a hand therapist. Pain levels for provocative tests, grip strength, and function were measured using a Numeric Rating Scale, Jamar Dynamometer, and the Patient-Rated Tennis Elbow Evaluation questionnaire at baseline, weeks 6 and 12. The Patient-Specific Functional Scale was also used for the intervention group.

RESULTS

There were no statistical differences between both groups for all clinical outcomes by 12 weeks (P> .05). Pain levels for all provocative tests and Patient-Rated Tennis Elbow Evaluation scores statistically improved within both groups (P < .05), however with small effect sizes observed. The Patient-Specific Functional Scale scores statistically improved for the intervention group by 12 weeks (P < .05).

CONCLUSION

The addition of a hand therapy workplace-based intervention did not result in superior clinical outcomes for pain, grip strength, and function. The study identified that a multimodal self-management approach used by hand therapists improved their patients' pain and function regardless of whether the education was given in the clinic or the workplace.

Lateral epicondylosis: A literature review to link pathology and tendon function to tissue-level treatment and ergonomic interventions

BACKGROUND

Common treatments for lateral epicondylosis (LE) focus on tissue healing. Ergonomic advice is suggested broadly, but recommendations based on biomechanical motion parameters associated with functional activities are rarely made. This review analyzes the role of body functions and activities in LE and integrates the findings to suggest motion parameters applicable to education and interventions relevant to activities and life roles for patients.

PURPOSE

This study examines LE pathology, tendon and muscle biomechanics, and population exposure outlining potentially hazardous activities and integrates those to provide motion parameters for ergonomic interventions to treat or prevent LE. A disease model is discussed to align treatment approaches to the stage of LE tendinopathy.

STUDY DESIGN

Integrative review METHODS: We conducted in-depth searches using PubMed, Medline, and government websites. All levels of evidence were included, and the framework for behavioral research from the National Institutes of Health was used to synthesize ergonomic research.

RESULTS

The review broadened the diagnosis of LE from a tendon ailment to one affecting the enthesis of the capitellum. It reinforced the continuum of severity to encompass degeneration as well as regeneration. Systematic reviews confirmed the availability of evidence for tissue-based treatments, but evidence of well-defined harm reducing occupational interventions was scattered amongst evidence levels. Integration of biomechanical studies and population information gave insight into types of potentially hazardous activities and provided a theoretical basis for limiting hazardous exposures to wrist extensor tendons by reducing force, compression, and shearing during functional activities.

CONCLUSIONS

These findings may broaden the first treatment approach from a passive, watchful waiting into an active exploration and reduction of at-risk activities and motions. Including the findings into education modules may provide patients with the knowledge to lastingly reduce potentially hazardous motions during their daily activities, and researchers to define parameters of ergonomic interventions.

The analgesic effect of joint mobilization and manipulation in tendinopathy: a narrative review

Objective: To summarize the available literature with regards to the potential analgesic effect and mechanism of joint mobilization and manipulation in tendinopathy. Results: The effect of these techniques in rotator cuff tendinopathy and lateral elbow tendinopathy, applied alone, compared to a placebo intervention or along with other interventions has been reported in some randomized controlled trials which have been scrutinized in systematic reviews. Due to the small randomized controlled trials and other methodological limitations of the evidence base, including short-term follow-ups, small sample size and lack of homogenous samples further studies are needed. Literature in other tendinopathies such as medial elbow tendinopathy, de Quervain's disease and Achilles tendinopathy is limited since the analgesic effect of these techniques has been identified in few case series and reports. Therefore, the low methodological quality renders caution in the generalization of findings in clinical practice. Studies on the analgesic mechanism of these techniques highlight the activation of the descending inhibitory pain mechanism and sympathoexcitation although this area needs further investigation. Conclusion: Study suggests that joint mobilization and manipulation may be a potential contributor in the management of tendinopathy as a pre-conditioning process prior to formal exercise loading rehabilitation or other proven effective treatment approaches.

How one treats lateral epicondylitis - a survey among Brazilian orthopedists

BACKGROUND

Lateral epicondylitis (LE), also known as tennis elbow, is the most common painful elbow condition. It affects approximately 1-3% of adults. There are various possible treatments described in the literature, but evidence to support a gold standard management protocol is lacking. Therefore, the objective of this study was to evaluate how Brazilian orthopaedists diagnose and treat lateral epicondylitis and compare these results with the available evidence.

METHODS

This is an observational, analytical, cross-sectional study. A questionnaire was prepared to obtain information from the participants with eight specific questions (2 on diagnosis and 6 on treatment). These questions were answered voluntarily by participants at 3 major congresses of orthopaedists in Brazil in 2018. The results were analysed in accordance with the overall number of responses and were evaluated among groups according to subspecialty.

RESULTS

We obtained a total of 501 questionnaires. Of these, 33 were excluded. The mean age was 38.67 years. The majority of respondents (91%) were male. We obtained 26.7% from specialists in hand surgery (Hand group), 36.5% from subspecialists in shoulder and elbow (Shoulder and Elbow group), and 36.8% from generalists in orthopaedics or from other subspecialties (General Orthopaedists group). For diagnosis, 24.4% did not initially request any imaging method. The most requested exam was ultrasonography (54.9%). The most prominent indication for initial treatment was physical therapy. For refractory cases, 78.3% of the respondents preferred doing a local infiltration. The most commonly used substance for local infiltrations was corticosteroids (89.6%). With respect to the surgical treatment option, 75.8% of those who recommend it prefer open techniques, and 24.2% prefer arthroscopic treatment. Of the total respondents, 12.8% did not recommend surgical treatment for LE.

CONCLUSION

Among Brazilian orthopaedists, the Cozen test is most frequently chosen, and ultrasound is the most commonly used imaging tool. Nonsurgically, oral nonsteroidal anti-inflammatory drugs (NSAIDs) plus physiotherapy is the most popular initial therapy, and corticosteroids are the most popular type of infiltration agent. Most surgeons recommended surgery after 6 months of nonsurgical treatment, and 75.8% preferred the open technique.

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.

The Effect of Scapular Muscle Strengthening on Functional Recovery in Patients With Lateral Elbow Tendinopathy: A Pilot Randomized Controlled Trial

CONTEXT

There is a lack of consensus on the best management approach for lateral elbow tendinopathy (LET). Recently, scapular stabilizer strength impairments have been found in individuals with LET.

OBJECTIVE

The purpose of this study was to compare the effectiveness of local therapy (LT) treatment to LT treatment plus a scapular muscle-strengthening (LT + SMS) program in patients diagnosed with LET.

DESIGN

Prospective randomized clinical trial.

SETTING

Multisite outpatient physical therapy.

PATIENTS

Thirty-two individuals with LET who met the criteria were randomized to LT or LT + SMS.

INTERVENTIONS

Both groups received education, a nonarticulating forearm orthosis, therapeutic exercise, manual therapy, and thermal modalities as needed. Additionally, the LT + SMS group received SMS exercises.

MAIN OUTCOME MEASURE

The primary outcome measure was the patient-rated tennis elbow evaluation; secondary outcomes included global rating of change (GROC), grip strength, and periscapular muscle strength. Outcomes were reassessed at discharge, 6, and 12 months from discharge. Linear mixed-effect models were used to analyze the differences between groups over time for each outcome measure.

RESULTS

The average duration of symptoms was 10.2 (16.1) months, and the average total number of visits was 8.0 (2.2) for both groups. There were no significant differences in gender, age, average visits, weight, or height between groups at baseline (P > .05). No statistical between-group differences were found for any of the outcome measures. There were significant within-group improvements in all outcome measures from baseline to all follow-up points (P < .05).

CONCLUSION

The results of this pilot study suggest that both treatment approaches were equally effective in reducing pain, improving function, and increasing grip strength at discharge as well as the 6- and 12-month follow-ups. Our multimodal treatment programs were effective at reducing pain and improving function up to 1 year after treatment in a general population of individuals with LET.

Exposure to greenspaces could reduce the high global burden of pain

Painful conditions are among the leading causes of years lived with disability, and may increase following the coronavirus pandemic, which has led to temporary closure of some healthcare services for people with chronic pain. To reduce this burden, novel, cost-effective and accessible interventions are required. We propose that greenspace exposure may be one such intervention. Drawing on evidence from neuroscience, physiology, microbiology, and psychology, we articulate how and why exposure to greenspaces could improve pain outcomes and reduce the high global burden of pain. Greenspace exposure potentially provides opportunities to benefit from known or proposed health-enhancing components of nature, such as environmental microbiomes, phytoncides, negative air ions, sunlight, and the sights and sounds of nature itself. We review the established and potential links between these specific exposures and pain outcomes. While further research is required to determine possible causal links between greenspace exposure and pain outcomes, we suggest that there is already sufficient evidence to help reduce the global burden of pain by improving access and exposure to quality greenspaces.

Clinical management of tendinopathy: A systematic review of systematic reviews evaluating the effectiveness of tendinopathy treatments

While the pathoetiology is disputed, a wide array of treatments is available to treat tendinopathy. The most common treatments found in the literature include therapeutic modalities, exercise protocols, and surgical interventions; however, their effectiveness remains ambiguous. The purpose of this study was to perform a systematic review of systematic reviews to determine the ability of therapeutic interventions to improve pain and dysfunction in patients with tendinopathy regardless of type or location. Five databases were searched for systematic reviews containing only randomized control trials to determine the effectiveness of treatments for tendinopathies based on pain and patient-reported outcomes. Systematic reviews were assessed via the Assessment of Multiple Systematic Reviews (AMSTAR) for methodological quality. From the database search, 3,295 articles were found, 107 passed the initial inclusion criteria. After further review, 25 systematic reviews were included in the final qualitative analysis. The AMSTAR scores were relatively high (8.8 ± 1.0) across the 25 systematic reviews. Eccentric exercises were the most common and consistently effective treatment for tendinopathy across systematic reviews. Low-level laser therapy and extracorporeal shockwave therapy demonstrated moderate effectiveness, while platelet-rich plasma injections demonstrated inconclusive evidence on their ability to decrease tendinopathy-related pain and improve function. Corticosteroids also showed some effectiveness for short-term pain, but for the long-term use deemed ineffective and at times contraindicated. Regarding surgical options, minimally invasive procedures were more effective compared to open surgical interventions. When treating tendinopathy regardless of location, eccentric exercises were the best treatment option to improve tendinopathy-related pain and improve self-reported function.

Management of lateral epicondylitis

Lateral epicondylitis is the most common cause of lateral elbow pain. Although also known as tennis elbow, lateral epicondylitis often develops as a work-related condition and therefore constitutes a major public health issue. This article reviews the pathophysiological factors involved in lateral epicondylitis, as well as the tools available for establishing the diagnosis and ruling out other causes of lateral elbow pain. Finally, the non-operative and surgical treatment options are discussed in detail.
