Abstract: The present study examined the effects of counter force forearm brace on isokinetic wrist extensor force production, stretch reflex latency, pain tolerance on passive stretching and proprioception of the force extensor muscles in both able-bodied subjects and subjects with tennis elbow. The effect of different tensions of the brace was investigated with the above tests. Fifteen able-bodied subjects and 15 subjects with tennis elbow were recruited and tested under 4 randomized conditions: (1) no brace, (2)brace with tension adjusted according to the subjects' forearm size, (3) brace with medium tension of 2.5 kgf, and (4) brace with high tension of 5 kgf. Results did not show significant difference in isokinetic wrist extensor strength and stretch reflex latencyin both groups. However, there was statistically significant difference in passive stretching test in both normal subject group and tennis elbow group (p=0.00l and p=0.O05, respectively). Significant difference was also found in testing the proprioception of subject with tennis elbow with the p-value of 0.032. Thought it did not shown significant difference in wrist extension strength, stretch reflex latency. It showed statistical significant in both able-bodied subjects and subjects in stretching pain tolerance. Results also showed statistically significant in proprioception in subjects with tennis elbow. It has a vital clinical implication of the brace to control pain and provide protection for subjects with tennis elbow by allowing the injured lateral epicondyle to recover. Furthermore, the result also revealed that pain threshold to passive stretching was increased as the tension of the brace for up to 5 kgf.
