Summary:

This study is a prospective evaluation testing inter- and intra-rater reliability of a simulated chair pick-up test. The study made use of a testing protocol involving subjects standing and grasping a hand board. The elbow is required to be held at the side with the shoulder aligned in neutral position. A tensile cord is adjusted so that the elbow is at 90 degrees of flexion. Subjects were tested for two 10-second runs.

The validity of the study was tested using 16 patients with clinical and magnetic resonance diagnosis of lateral epicondylosis. There was a very high correlation between elbow pain with activity and mean peak force obtained through elbow testing with the chair pick-up test. There was similarly a strong correlation between elbow pain with activity and mean total force demonstrated. This test appears to have a very high correlation with symptoms and demonstrates excellent reliability in reproducibility.
