Lin CH, Lien YH, Wang SF, Tsauo JY: Hip and knee proprioception in elite, amateur, and novice tennis players. Am J Phys Med Rehabil 2006;85:216–221.Objectives:The purposes of this study were: (1) to show the differences of lower limb proprioception in three different groups of normal male subjects—elite, amateur, and novice tennis players—and between the skill-dominant and stance-dominant hip and knee and (2) to test the sensitivity of closed-chain reposition test in the three groups.Design:There were 22, 20, and 20 subjects in the three groups, respectively. Proprioception was tested with the closed-chain reposition method. Absolute error and variable error were calculated. One-way analysis of variance and Tukey's test were used to test the differences.Results:The proprioception of the hip joints of the elite players was significantly better than that of the other two groups in absolute error (P < 0.0167). In variable error analysis, the proprioception of the stance-dominant leg of the elite players was significantly better than that of the novice players (P < 0.0033).Conclusions:Findings of this study supported that the proprioception of elite players was the best. The closed-chain reposition test had good discriminating power between the elite players and the others.
