Scapular excursion and the wrist speed were studied before and after instruction and practice designed to achieve symmetrical scapular movement.
Subjects were 10 female and 6 male patients, aged 44 to 78 years (chi=60.3, SD=11.2), with diagnosed shoulder pathologies.
Subjects were videotaped performing a reaching task. Pain status was monitored. The subjects were instructed to make the scapular movement symmetrical. They then repeated the task, while being videotaped, to monitor the effect of instruction.
Individuals with asymmetric upper-extremity starting positions had excessive vertical motion of the involved scapula, which they controlled after instruction. Peak wrist speed of the involved upper extremity was lower only after instruction.
Even in the absence of biomechanical factors or pain, excessive scapular vertical motion appears to occur in the involved upper extremities of individuals recovering from unilateral shoulder problems. Improved scapular control can follow simple verbal instruction and practice, with a slight decrement in wrist speed.
在旨在实现肩胛运动对称的指导和练习前后，对肩胛活动度和腕部速度进行了研究。
受试者为10名女性和6名男性患者，年龄在44至78岁之间（均值=60.3，标准差=11.2），均被诊断患有肩部疾病。
对受试者进行伸手够物任务的录像。监测疼痛状况。指导受试者使肩胛运动对称。然后他们在录像的同时重复该任务，以监测指导的效果。
上肢起始位置不对称的个体，患侧肩胛有过度的垂直运动，在接受指导后得到了控制。仅在接受指导后，患侧上肢的腕部峰值速度降低。
即使不存在生物力学因素或疼痛，从单侧肩部问题恢复的个体的患侧上肢似乎也会出现肩胛过度垂直运动。简单的言语指导和练习可改善肩胛控制，同时腕部速度略有下降。
