Abstract
BACKGROUND Lateral epicondylitis (LE), also called tennis elbow, is a common musculoskeletal disorder that causes pain in the elbow area and is highly prevalent in assembly workers who repeatedly move their wrists. OBJECTIVE The purpose of this study was to compare the wrist ROM and muscle strength of assembly workers with and without LE. METHODS Forty-five male assembly line workers (23 with LE) participated in the study. Participants had their wrist range of motion (flexion, extension, ulnar deviation, and radial deviation) and strength (wrist flexors, extensors, and hand grip) measured using Smart KEMA sensors. RESULTS Workers with LE showed significantly reduced wrist extension and radial deviation ROM compared to workers without LE, with no significant differences in wrist flexion and ulnar deviation ROM between groups. Workers with LE had significantly lower wrist extensor strength compared to workers without LE, and there was no significant difference in wrist flexor and grip strength between the two groups. CONCLUSIONS For workers with LE, the difference in wrist ROM and muscle strength will be useful for planning intervention and evaluating treatment outcomes for assembly workers with LE.

An Investigation of Maximal Strength of the Upper Limb Bilaterally in Individuals With Lateral Elbow Tendinopathy: A Systematic Review With Meta-Analysis. Phys Ther 2021; 101:6380796. [PMID: 34636922 DOI: 10.1093/ptj/pzab230] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 07/22/2021] [Accepted: 08/17/2021] [Indexed: 11/13/2022]
Abstract
OBJECTIVE The aim of this study was to investigate whether there is evidence of bilateral upper limb strength deficits in individuals with unilateral lateral elbow tendinopathy (LET). METHODS The electronic databases Medline via Ovid, PubMed, and Scopus were searched from inception to March 2020. Included studies encompassed maximal strength outcomes of any upper limb and appendicular musculature in individuals with LET and an asymptomatic comparator. Study quality was rated using a modified version of the Epidemiological Appraisal Instrument. Hedges g effect sizes (ES) and 95% CIs were calculated for comparisons of maximal strength in the LET group and an asymptomatic control group. Meta-analysis using a random-effects model was performed when possible. RESULTS Fourteen studies were included. Quality appraisal resulted in a mean Epidemiological Appraisal Instrument score of 46% (SD = 10%). Meta-analysis revealed strength deficits in shoulder abduction (pooled ES = -0.37 [95% CI = -0.62 to -0.12]) and shoulder external rotation (pooled ES = -0.55 [95% CI = -0.83 to -0.28]) of the symptomatic limb compared with an asymptomatic control group. Meta-analysis also revealed maximal strength deficits in the upper trapezius (pooled ES = -0.26 [95% CI = -0.49 to -0.02]) of the asymptomatic limb compared with an asymptomatic control group. There was also consistent evidence for strength deficits in the serratus anterior, lower trapezius, and wrist extensor muscles and deficits in grip strength of the symptomatic limb as well as strength deficits in the wrist extensor muscles of the asymptomatic limb in individuals with unilateral LET. CONCLUSION In individuals with LET, there were maximal strength deficits in shoulder abduction, shoulder external rotation, serratus anterior and lower trapezius muscles, and wrist extension, as well as deficits in grip strength of the symptomatic limb compared with an asymptomatic control group. In addition, there appeared to be strength deficits in the upper trapezius muscle, wrist extension, and metacarpophalangeal joint flexion and extension, as well as deficits in grip strength of the asymptomatic limb in individuals with LET compared with an asymptomatic control group. These results suggest bilateral strength deficits. IMPACT These findings highlight the importance of a thorough physical examination and appropriate strengthening intervention for the upper limb with a focus on shoulder and scapular stabilizers, in addition to forearm muscles, in individuals with LET. LAY SUMMARY In people with tennis elbow, widespread strength deficits, including weakness of the shoulder, forearm, and wrist muscles, may exist. Interestingly, some of these weaknesses appear on both the affected and the unaffected sides in people with tennis elbow. A physical therapist can help strengthen these areas.

Indian J Occup Environ Med 2021; 25:138-146. [PMID: 34759600 PMCID: PMC8559880 DOI: 10.4103/ijoem.ijoem_223_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 07/06/2020] [Accepted: 09/17/2020] [Indexed: 11/05/2022] Open
Abstract
Background: The repetitive and prolonged exertion of grip and pinch strength are current among carpet weaver tasks. The three objectives of this study were (1) to investigate the relationship between symptoms of musculoskeletal disorders and grip and pinch strength of carpet weavers in carpet weaving workshops in Kerman province, (2) to compare the grip and pinch strength of carpet weavers with normal values, and (3) to identify the relationship between hand postures of carpet weavers during work and force exertion. Methods: In this cross-sectional study, grip strength and key, tip and palmar pinch strengths of 101 female carpet weavers aged 20 to 71 years were measured in Kerman province, in 2018. Nordic Musculoskeletal Questionnaire (Extended version) was also used to evaluate musculoskeletal disorders. Results: Bivariate and multivariate linear regression analyses showed that participants who suffered from musculoskeletal disorders had lower grip and pinch strength than others and this decrease was statistically significant in upper back, wrists/hands, and knees. Moreover, there was a significant difference between grip and three types of pinch strength of carpet weavers and normal values. Furthermore, for both hands, the grip strength in the position recommended by American Society of Hand Therapists was significantly greater than that in the normal position carpet weavers usually adopt. Conclusion: Based on the results, the high prevalence of musculoskeletal disorders has led to a significant decrease in the grip and pinch strength of carpet weavers. Therefore, it is necessary to undertake ergonomic interventions in designing the carpet weaving workstation.

Abstract
Background Extracorporeal shock-wave therapy (ESWT) and wrist-extensor splints (WESs) are two commonly used methods in the treatment of lateral epicondylitis. In this study, the efficacy of these two methods was compared. Methods The study was planned as a prospective randomized controlled study. A total of 67 patients were enrolled. The patients were divided into two groups: group 1 received ESWT (32 patients) and group 2 received WES (35 patients). Patients in group 1 underwent four sessions of ESWT once every week. In each session, an ESWT device at 10–12 Hz, 2,000 pulses, and 1.6–1.8 bar pressure was used. Patients in group 2 used a wrist splint, holding the wrist at 30°–45° extension for 4 weeks. Patients were assessed for handgrip strength, pain at rest, pain while working, and quality of life. Data were collected before and after treatment (at weeks 4, 12, and 24). A visual analog scale was used to evaluate pain at rest and while working, a hand dynamometer for handgrip strength, subscales of the SF36 Health Survey to evaluate quality of life, and the Turkish version of the patient-rated tennis-elbow evaluation was used to evaluate functioning of the affected arm during various daily life activities. Results In both ESWT and WES groups, although there were considerably significant improvements (P<0.001) in the parameters evaluated (pain at rest and while working, handgrip strength, Patient-Rated Tennis Elbow Evaluation, Nirschl score, and SF36 subscales) were observed at 4, 12, and 24 weeks compared to pretreatment values, there was no statistically significant difference between the two groups in terms of our evaluation parameters at the three time points (P>0.05). Conclusion Both ESWT and WES applications were found to yield significantly superior results when compared to pretreatment values. In comparison of the two groups, on the other hand, there was no statistically significant difference.

Abstract
BACKGROUND Lateral elbow tendinopathy (LET) is a common complaint causing characteristic pain in the lateral elbow and upper forearm, and tenderness of the forearm extensor muscles. It is thought to be an overuse injury and can have a major impact on the patient's social and professional life. The condition is challenging to treat and prone to recurrent episodes. The average duration of a typical episode ranges from 6 to 24 months, with most (89%) reporting recovery by 1 year. OBJECTIVES This systematic review aims to summarise the evidence concerning the clinical effectiveness and cost-effectiveness of conservative interventions for LET. DATA SOURCES A comprehensive search was conducted from database inception to 2012 in a range of databases including MEDLINE, EMBASE and Cochrane Databases. METHODS AND OUTCOMES We conducted an overview of systematic reviews to summarise the current evidence concerning the clinical effectiveness and a systematic review for the cost-effectiveness of conservative interventions for LET. We identified additional randomised controlled trials (RCTs) that could contribute further evidence to existing systematic reviews. We searched MEDLINE, EMBASE, Allied and Complementary Medicine Database, Cumulative Index to Nursing and Allied Health Literature, Web of Science, The Cochrane Library and other important databases from inception to January 2013. RESULTS A total of 29 systematic reviews published since 2003 matched our inclusion criteria. These were quality appraised using the Assessment of Multiple Systematic Reviews (AMSTAR) checklist; five were considered high quality and evaluated using a Grading of Recommendations, Assessment, Development and Evaluation approach. A total of 36 RCTs were identified that were not included in a systematic review and 29 RCTs were identified that had only been evaluated in an included systematic review of intermediate/low quality. These were then mapped to existing systematic reviews where further evidence could provide updates. Two economic evaluations were identified. LIMITATIONS The summary of findings from the review was based only on high-quality evidence (scoring of > 5 AMSTAR). Other limitations were that identified RCTs were not quality appraised and dichotomous outcomes were also not considered. Economic evaluations took effectiveness estimates from trials that had small sample sizes leading to uncertainty surrounding the effect sizes reported. This, in turn, led to uncertainty of the reported cost-effectiveness and, as such, no robust recommendations could be made in this respect. CONCLUSIONS Clinical effectiveness evidence from the high-quality systematic reviews identified in this overview continues to suggest uncertainty as to the effectiveness of many conservative interventions for the treatment of LET. Although new RCT evidence has been identified with either placebo or active controls, there is uncertainty as to the size of effects reported within them because of the small sample size. Conclusions regarding cost-effectiveness are also unclear. We consider that, although updated or new systematic reviews may also be of value, the primary focus of future work should be on conducting large-scale, good-quality clinical trials using a core set of outcome measures (for defined time points) and appropriate follow-up. Subgroup analysis of existing RCT data may be beneficial to ascertain whether or not certain patient groups are more likely to respond to treatments.

Abstract
Objective. Tennis elbow is a common cause of upper limb dysfunction and a primary reason for pain at the lateral aspect of the elbow. The purpose of this study was to investigate the effects of three commonly used orthoses on pain severity. An elbow band, an elbow sleeve, and a wrist splint were assessed for their ability to reduce the level of reported pain. Method. A crossover randomized controlled trial was used. The orthoses were worn in a randomized order, and all participants were required to complete a control trial for which they wore a placebo orthosis. 52 participants with lateral epicondylalgia were recruited, and the level of pain at their elbow was recorded using the visual analogue scale (VAS). Results. The reported pain for all orthoses was lower than that of the placebo (P < 0.05). Pain reduction was significantly greater with a counterforce elbow band or a counterforce elbow sleeve compared to a wrist splint (P < 0.01). There was no significant difference between a counterforce elbow band and a counterforce elbow sleeve (P = 0.23). Conclusion. All the types of orthoses studied showed an immediate improvement on pain severity in people with lateral epicondylalgia. The counterforce elbow orthoses (elbow band and elbow sleeve) presented the greatest improvement, suggesting that either of them can be used as a first treatment choice to alleviate the pain in people with tennis elbow.

Abstract
STUDY DESIGN Case report. BACKGROUND Addressing weakness of the shoulder region, especially the rotator cuff and scapular musculature, is often suggested clinically for the treatment of individuals with lateral epicondylalgia. However, to our knowledge, the clinical effectiveness of this approach has not been established. CASE DESCRIPTION The patient was a 54-year-old woman with a 5-month history of right lateral elbow pain, whose symptoms were reproduced with clinical tests typically used to diagnose lateral elbow tendinopathy. The patient also demonstrated weakness in her middle and lower trapezius muscles, and the medial border of her scapula, measured with a tape measure, was 11 cm lateral from the spinous processes of the thoracic spine with the patient standing in relaxed stance. Based on improved grip strength and reduced associated elbow pain when tested with the scapula manually corrected in a more adducted position, treatment focused solely on strengthening of the middle and lower trapezius muscles over a 10-week period. OUTCOMES Following the intervention, the patient presented with improved scapular position, with the medial border of the scapula being 9 cm lateral to the midthoracic spine. The patient's middle and lower trapezius strength improved from 3+/5 and 4-/5, respectively, to 5/5, and her grip strength from 26.1 to 42.2 kg. The patient's scores on the Disabilities of the Arm, Shoulder and Hand questionnaire also improved from 44.2 at the initial evaluation to 0 at the completion of therapy, with the patient being able to perform all of her daily activities in a pain-free manner. DISCUSSION The results of this case report suggest that assessment and treatment of scapular musculature warrant consideration in the management of individuals with lateral epicondylalgia. LEVEL OF EVIDENCE Therapy, level 4.
