最近表明，如果从对侧手臂向目标手臂的手腕提供轻微的手指触摸，则用于提起和运输手持物体的抓握力的大小减小[A.S.阿鲁因，偏瘫患者握力的支持特异性调节，Arch. Phys. Med. Rehabil。86（2005）768-775]。在这项研究中，我们调查了手指触摸沿着目标手臂的位置是否会影响握力的减少。受试者执行相同的任务，即在不涉及对侧手臂的情况下举起和运输仪器物体，并且当对侧手臂的食指触摸提供给手腕、拇指、前臂中部和手持物体时。在所有条件下，与无触摸条件相比，手指触摸的握力减少了大约相同的量，这表明其减少与手指与目标手臂的特定接触点无关。研究结果提供了额外的证据，支持在日常生活活动中使用第二只手臂，并强调未来研究的重要性。对侧手臂感觉输入对握力控制的影响。
It was recently shown that the magnitude of grip force used to lift and transport a hand-held object decreased if a light finger touch from the contralateral arm was provided to the wrist of the target arm [A.S. Aruin, Support-specific modulation of grip force in individuals with hemiparesis, Arch. Phys. Med. Rehabil. 86 (2005) 768–775]. In this study, we investigated whether the location of the finger touch along the target arm affects the way grip force is reduced. Subjects performed the same task of lifting and transporting an instrumented object with no involvement of the contralateral arm and when an index finger touch of the contralateral arm was provided to the wrist, thumb, mid-forearm, and the hand-held object. Grip force was reduced by approximately the same amount in all conditions with the finger touch compared to the no touch condition suggesting that its reduction was not associated with a particular point of contact of the finger with the target arm. The results of the study provide additional evidence to support of the use of a second arm in the performance of activities of daily living and stress the importance of future studies investigating contralateral arm sensory input on grip force control.
