Introduction: It is known that Horizontal flexion test (HFT) is positive on symptomatic side of lateral epicondylitis patients. HFT is a test which fixes angulus inferior scapulae and carries out level adduction of the humerus, reflecting the muscle tonus of teres major. In this study, we investigated positive ratios of the HFT for lateral epicondylitis between patients and non-patients (tennis players and non-tennis players).

Subjects and Methods: 30 patients (16 men and 14 women, age 26 - 76) were diagnosed as lateral epicondylitis (30 elbows). 54 healthy adults (their dominant hand right) and a tennis group 24 persons (8 men and 16 women, age 19 - 65), and a non-tennis group are 30 persons (15 men and 15 women, age 19 - 25). The HFT carried out patients and non-patient's both-sides upper limbs correspondingly at a previous work, the side which has restriction with 10 degrees or more of right-and-left differences. In addition, we obtained their consent all cases on this study.

Results: A symptomatic side of the HFT of positive ratios was 100% in all patients. Positive ratios of the whole healthy adults were 13.0%, and positive ratios of the tennis group was 20.8%, positive ratios of non-tennis group was 6.7%, moreover, specificity of the tennis group were significantly different than non-tennis group (p = 0.0043).

Discussion: The previous study reported that internal rotation restrictions of a shoulder joint are observed in the dominant hand of the tennis player which is not presenting the functional disability, and internal rotation restrictions will serve as an index of functional disability prevention. In this study, results showed that positive ratios of the tennis group were significantly different than non-tennis group. It is a possibility that the muscle tonus of the teres major which arises to a tennis player is related with restriction of a shoulder joint.
