We tested the hypothesis that the use of elastic knee bandages and ankle weights improve proprioception of the knee joint in uninjured female dancers. Twenty-six full-time college dance students without a history of knee injury were tested using a modified Thomas splint and pulley system. The pulley system enabled a fixed angle of knee flexion to be set. The participants were then asked to reproduce the set angle with and without being blindfolded. Each knee was assessed without modification, followed by the use of an elastic knee bandage, a standard 2-kg ankle weight, and bandage and weight together. The tests were repeated, using the absolute error in angle reproduction as a measure of proprioceptive ability. Compared with the free knee, elastic bandages, ankle weights, and elastic bandage together with weights improved knee proprioception. We found that proprioception by reproduction of a set angle using physical recall (ie blindfolded) is different from visual recall. In all test settings, the absolute error in angle reproduction was smaller by physical recall compared with visual recall, and the difference was statistically significant (p < 0.01). There was, however, no difference in the performance of dancers from different disciplines. (Hong Kong j. orthop. surg. 2001;5(1):52-57)
