About

The purpose of this study is to evaluate the effectiveness of blood flow restriction training (BFRT) verses Mulligan's technique in improving pain, grip strength, and functional outcomes in patients with lateral epicondylitis (LE).

Full description

Lateral epicondylitis (LE) is a work-related musculoskeletal disorder caused by the tendon's inflammation of either one or both of the extensor carpi radialis longus and extensor carpi radialis brevis. It is often referred to tennis elbow. It manifests as pain on the lateral side of the elbow and reduced range of motion, which results in weakening and impairment in the forearm muscles (Ahmad et al., 2013).With no sex predisposition, LE is a widespread ailment that affects up to 3% of the population (Vaquero-Picado et al., 2017). Etiological factors of LE include overuse, repetitive movements, physically forceful occupational activities, exercise errors, misalignments, flexibility problems, ageing, muscle imbalances and psychological (e.g. job strain) factors. The estimated incidence of LE ranges from 2.0-11.3 per 100 worker-years in specific activity sectors (Herquelot et al., 2013; Bongers et al., 2002).

Enrollment: 45 patients

Volunteers: No Healthy Volunteers

Inclusion criteria

1) 36 subjects of both gender aged between 18 and 50 years with a positive test of LE (Positive Cozen's, Maudsley's, and/or Mill's test), which has been determined based on physical therapy assessment procedures; 2) the presence of pain in the lateral epicondyle of the humeral bone; and 3) show decreased muscle strength and functional ability.

Exclusion criteria

While the exclusion criteria of this study will be 1) refusal to be a sample in this study; 2) presences of bilateral symptoms; 3) presences of sensory and motor impairment of the upper extremities; 4) samples with systemic disease and metabolic disorders; 5) history of trauma and surgery on the elbow; 6) having a history of malignancy and peripheral vascular disorders.
