Is chronic ankle instability associated with impaired muscle strength? Ankle, knee and hip muscle strength in individuals with chronic ankle instability: a systematic review with meta-analysis.

Objective: Determine whether impairments in lower limb muscle strength exist in individuals with chronic ankle instability (CAI) compared with uninjured controls.

Design: Systematic review with meta-analysis.

Data Source: A comprehensive search of PubMed, Cochrane, CINAHL, Web of Science and EMBASE electronic databases from inception to 10 February 2019.

Unsupervised Isometric Exercise versus Wait-and-See for Lateral Elbow Tendinopathy.

Purpose: This study aimed to investigate the effect of unsupervised isometric exercise compared with a wait-and-see approach on pain, disability, global improvement, and pain-free grip strength in individuals with lateral elbow tendinopathy.

Methods: Forty participants with unilateral lateral elbow tendinopathy of at least 6 wk duration were randomized to either wait-and-see (n = 19) or a single supervised instruction session by a physiotherapist, followed by an 8-wk unsupervised daily program of progressive isometric exercise (n = 21). Primary outcomes were Patient-Rated Tennis Elbow Evaluation, global rating of change on a six-point scale (dichotomized to success and no success) and pain-free grip strength at 8 wk.

Is synergistic organisation of muscle coordination altered in people with lateral epicondylalgia? A case-control study.

Background: Lateral epicondylalgia is a common musculoskeletal disorder and is associated with deficits in the motor system including painful grip. This study compared coordination of forearm muscles (muscle synergies) during repeated gripping between individuals with and without lateral epicondylalgia.

Methods: Twelve participants with lateral epicondylalgia and 14 controls performed 15 cyclical repetitions of sub-maximal (20% maximum grip force of asymptomatic arm), pain free dynamic gripping in four arm positions: shoulder neutral with elbow flexed to 90° and shoulder flexed to 90° with elbow extended both with forearm pronated and neutral.

Diagnostic ultrasound imaging for lateral epicondylalgia: a case-control study.

Introduction: Lateral epicondylalgia (LE) is clinically diagnosed as pain over the lateral elbow that is provoked by gripping. Usually, LE responds well to conservative intervention; however, those who fail such treatment require further evaluation, including musculoskeletal ultrasound. Previous studies of musculoskeletal ultrasound have methodological flaws, such as lack of assessor blinding and failure to control for participant age, sex, and arm dominance.
