The objective was to assess the associations between changes in pain and grip strength and manual tests among patients with chronic tennis elbow. ⋯ Pain thresholds at the lateral epicondyles are strongly associated with pain on palpation and with a positive Mills test. Resisted wrist extension test results reflect decreased grip strength. Impaired function of the hand is associated with the number of positive clinical tests. Pain threshold evaluation is a simple, easy, inexpensive method that provides useful additional quantitative data on pain and disability among patients with chronic tennis elbow.
