The purpose of this study was to examine the effects of recurrent lateral ankle sprains on subjects' active and passive judgments of joint position. Fourteen subjects with recurrent unilateral ankle sprains contributed data to two groups: 1) In Group 1, the subjects' 14 sprained ankles were tested and 2) in Group 2, the same 14 subjects' contralateral nonsprained ankles were tested. An additional seven subjects with no history of injury to either ankle comprised Group 3 with 14 nonsprained control ankles. The experimenter tested all blindfolded subjects with active and passive attempts at replicating predetermined ankle joint positions in the inversion-eversion range of motion. An isokinetic dynamometer measured joint position. A two-way analysis of variance indicated no significant effect caused by ankle injury or noninjury. Passive judgments were significantly better than active judgments of joint position (p less than .01) in the nonsprained control group. The results suggest that joint receptors play a dominant role in joint angle detection and that muscle receptors are more valuable in the perception of joint movement.
本研究的目的是检验复发性外侧踝关节扭伤对受试者关节位置主动和被动判断的影响。14名患有复发性单侧踝关节扭伤的受试者为两组提供了数据:1)在第1组中,对受试者的14个扭伤脚踝进行了测试;2)在第2组中,对同一14名受试者的对侧未扭伤脚踝进行了测试。另外7名无脚踝损伤史的受试者组成第3组,有14个未扭伤的对照脚踝。实验者对所有蒙住眼睛的受试者进行主动和被动尝试,以在踝关节内翻-外翻运动范围内复制预定的关节位置。用等速测力计测量关节位置。双向方差分析表明,踝关节损伤或未损伤未产生显著影响。在未扭伤的对照组中,关节位置的被动判断明显优于主动判断(p小于0.01)。结果表明,关节感受器在关节角度检测中起主导作用,而肌肉感受器在关节运动感知中更有价值。
