Outcomes of a pilates-based intervention for individuals with lateral epicondylosis: A pilot study

BACKGROUND: Core stability and flexibility, features of Pilates exercise, can reduce loads to the upper extremities. Reducing loads is essential to improve symptoms for individuals with lateral epicondylosis. Although Pilates exercise has gained popularity in healthy populations, it has not been studied for individuals with lateral epicondylosis. OBJECTIVE: The purpose of this study was to determine if adding Pilates-based intervention to standard occupational therapy intervention improved outcomes as measured by the Patient-Rated Tennis Elbow Evaluation (PRTEE) more than standard intervention for individuals with lateral epicondylosis. METHODS: Participants (N = 17) were randomized to the standard intervention group or Pilates-based intervention group. All participants received standard intervention. The Pilates-based intervention group additionally completed abdominal strengthening, postural correction, and flexibility. RESULTS: For both groups, paired t-tests showed significantly improved PRTEE scores, 38.1 for the Pilates-based intervention group, and 22.9 for the standard intervention group. Paired t-test showed significantly improved provocative grip strength and pain for both groups. Independent t-tests showed no significant difference between groups in improved scores of PRTEE, pain, and provocative grip. CONCLUSIONS: Although the Pilates-based intervention group showed greater improvement in PRTEE outcome, provocative grip, and pain, scores were not significantly better than those of the standard intervention group, warranting further research.
