这项研究使用关节运动和表面肌电信号检测器比较了有和没有YIP的高尔夫球手。研究人员对50名高尔夫球手(25名有YIP症状和25名没有YIP症状)进行了推杆研究。所有的推杆都被录了下来。表面肌电图术评估手臂的协同收缩。一个CyberGlove II(沉浸技术，加利福尼亚州帕洛阿尔托)评估了右臂的角度运动。初步分析是通过主观抱怨YIP进行的，而次要分析是通过非自愿运动的视频证据进行的。当按主观主诉分组时，任何运动参数都没有差异。根据非自主运动的视频证据分组时，YIPS病例在手腕旋前/旋后有更多(P<；0.001)角运动，并有腕屈伸肌协同收缩的趋势(YIPS：7/17，41.2%；无YIPS：6/33，18.2%)。有视频证据的高尔夫球手在推杆时有不自主运动的迹象，在旋前/旋后运动中右手腕过度旋转，并且如先前报道的那样，手腕屈/伸肌群有收缩的趋势。(C)2011年运动无序社
This study compared golfers with and without the yips using joint movement and surface electromyographic detectors. Fifty golfers (25 with and 25 without complaints of the yips) were studied while putting. All putts were videotaped. Surface electromyography assessed arm cocontraction. A CyberGlove II (Immersion Technologies, Palo Alto, CA) assessed right-arm angular movements. Primary analysis was done by subjective complaint of the yips, whereas secondary analysis was done by video evidence of an involuntary movement. When grouped by subjective complaints, there were no differences in any movement parameter. When grouped by video evidence of an involuntary movement, yips cases had more (P < 0.001) angular movement in wrist pronation/supination and a trend (P = 0.08) for wrist flexor/extensor cocontraction (yips: 7 of 17, 41.2%; no yips: 6 of 33, 18.2%). Golfers with video evidence of an involuntary movement while putting have excessive rotation of the right wrist in a pronation/supination motion and, as previously reported, a trend for wrist flexor/extensor cocontraction.
