The handgrip strength of 65 normal control subjects and 166 patients with unilateral frontal- or temporal-lobe excisions was assessed. Because of the known sex differences in strength, the results for the men and women were analysed separately. The grip strength of men with left frontal-lobe lesions was found to be within the normal range, but women with comparable excisions from the left frontal lobe had a residual impairment in strength on both hands. The men with right frontal-lobe lesions had a significant reduction in the strength of only the left hand, and the women in this group displayed a similar tendency. The deficits were interpreted in terms of a loss or disruption of input from the premotor area to the primary motor cortex.
对65名正常对照者和166名单侧额叶或颞叶切除术患者的握力进行了评估。由于已知力量存在性别差异，因此对男性和女性的结果分别进行了分析。发现左侧额叶病变男性的握力在正常范围内，但左侧额叶进行类似切除的女性双手力量均有残余损害。右侧额叶病变男性仅左手力量显著下降，该组女性也表现出类似趋势。这些缺陷被解释为运动前区向初级运动皮层的输入丧失或中断。
