OBJECTIVES: To compare static strength characteristics of the upper extremity musculature in female recreational tennis players who have lateral epicondylalgia with those of non-symptomatic tennis players and a control group of women who do not play tennis. BACKGROUND: A paucity of research exists describing the relationship between lateral epicondylalgia and strength characteristics of the upper extremity musculature despite the functional relationship that exists between the shoulder, elbow, and wrist. METHODS: Sixty-three females, 21 in each group, were recruited: symptomatic tennis players (STP) with lateral epicondylalgia, non-symptomatic tennis players (NSTP), and controls. Data collection was performed during a single session when strength of selected muscle groups of the dominant upper extremity was measured using a combination of force transducers. Strength ratios of selected muscle groups were calculated. RESULTS: The STP group reported median pain level of 3/10 on a numeric pain rating scale and 16 weeks symptom duration. The STP group had weaker lower trapezius (mean difference,-9.0 N; 95% CI: -13.5 to -4.4 N) and wrist extensors (-12.7 N; -24.4 to -1.1) strength and higher shoulder internal/external rotation (1.9; 0.02, 0.35) and upper/lower trapezius (1.32; 0.41, 2.23) strength ratios when compared to the NSTP group. Compared to the control group, the STP group demonstrated significantly higher shoulder internal/external rotation (0.21; 0.04, 0.38) and wrist flexion/extension (0.14; 0.01 to 0.27) strength ratios. CONCLUSIONS: In this group of recreational female tennis players, significant differences in strength and strength ratio characteristics were identified. While the design of the study precludes a cause and effect relationship to be established, the results suggest potential muscle groups of interest for further study or treatment.
