Effects of a Conventional Treatment Plus Scapular Exercises Program in Patients With Chronic Lateral Elbow Tendinopathy: A Pre-Post Single-Group Study.

Abstract

Weakness of the shoulder girdle muscles has been reported in patients with chronic lateral elbow tendinopathy. The aim of this study was to assess the short- and long-term effects of a conventional treatment plus scapular exercises program in patients with chronic lateral elbow tendinopathy. A single-group prestudy and poststudy were conducted. The primary outcome was the Patient-Rated Tennis Elbow Evaluation questionnaire score. Secondary outcomes were grip strength; Disabilities of the Arm, Shoulder, and Hand questionnaire score; Visual Analogue Scale score at rest and at grip, and presence of scapular dyskinesis. A total of 65 patients (72.3% females), with a mean age of 41.8years, were analyzed. At the end of 6weeks, the results showed clinically and statistically significant differences (P < .05). At 1-year follow-up, the differences were: Patient-Rated Tennis Elbow Evaluation -31 points (P < .001); grip strength +33.6% (P < .001); Disabilities of the Arm, Shoulder, and Hand -34.2 points (P < .001); Visual Analogue Scale at rest -2.5cm (P < .001); and Visual Analogue Scale at grip -2.3cm (P < .001). At the end of 6weeks and at 1-year follow-up, conventional treatment plus scapular exercises program showed statistically and clinically significant differences in all functional outcomes assessed in patients with lateral elbow tendinopathy.
