The effect of a neoprene sleeve on knee joint position sense.

The aims of the study were, first, to assess the effect of a neoprene knee brace on prop rioceptive acuity of normal subjects and, second, to assess the relationships between a variety of tests of proprioceptive acuity. Twenty healthy, physically active subjects had absolute error scores measured while carrying out three different established tests of proprioceptive ability (active tracking, active reproduction, and perceived angle tests) under two conditions, either with or without the presence of a neoprene sleeve. The neoprene sleeve significanltly improved the degree of error scores in all tests. For the active tracking, test accuracy was improved by 28% (p = 0.004), the angle reproduction test showed a 23% increase in accuracy (p = 0.029), and the accurancy of the perceived angle test improved by 27% (p = 0.035). The relationship between magnitude of error scores between the test all showed nonsignificant low correlation. The findings of this study support the previous literature, which indicates that the application of a knee sleeve improves proprioceptive acuity. The study also indicates that when testing proprioceptive acuity, a test battery should be used because of the limited correlatiotn between any of the tests used.
