DOI : 10.30621/jbachs.2019.503 Purpose: Lateral epicondylitis can cause limitations in upper extremity functions of patients due to the decrease in upper extremity muscle strength and endurance in patients. The aim of this study is to determine the effect of muscle strength and endurance on upper extremity functions in patients with lateral epicondylitis.

Methods: Forty-five patients (mean age: 47.60±3.22, 30 females, 15 male) diagnosed with chronic lateral epicondylitis were included in the study. Upper extremity muscle endurance of the patients was evaluated with unsupported arm exercise test (in 1st and 2nd diagonal pattern), upper extremity muscle strength of the patients was evaluated with Hand Held Dynamometer (HHD), and upper extremity functions of the patients were evaluated with Lateral Epicondylitis Function Scale (LEFS) scores.

Results: There was a moderate negative correlation between the unsupported arm exercise test endurance on the affected side and the LEFS scores of the patients with lateral epicondylitis (p<0.05), and a moderate negative correlation was found between shoulder extensor, elbow flexor, elbow supinator, and wrist extensor muscle strength and LEFS scores (p<0.05).

Conclusion: Decreasing muscular endurance and strength in patients with chronic lateral epicondylitis cause a decrease in the upper extremity functions. We consider that muscular endurance and strengthening exercises should be included in the physiotherapy programmes in order to increase the upper extremity functions in patients with chronic lateral epicondylitis.
