Manugraphy with three different cylinder sizes was used to quantify the contribution of fingers, thumb and palm to grip force in patients with unilateral cubital tunnel syndrome. Forces in the affected and contralateral hands differed by up to 29%. Although grip force is usually maximal when gripping small handles, ulnar nerve palsy resulted in similar absolute grip forces using the 100-mm and 200-mm cylinders. The contact area between the affected hand and the cylinders was reduced by 5%-9%. We noted a high correlation between the contact area and grip force, visible atrophy and permanently impaired sensibility. The load distribution differed significantly between both hands for all cylinder sizes. When gripping large objects, the main functional impairment in cubital tunnel syndrome is weakness in positioning and stabilizing the thumb. Weak intrinsic finger muscles are responsible for loss of force when gripping small objects. III.
采用三种不同圆柱尺寸的手法肌力描记法，来量化单侧肘管综合征患者手指、拇指和手掌对握力的贡献。患侧手与对侧手的力量差异高达29%。尽管抓握小把手时握力通常最大，但尺神经麻痹导致使用100毫米和200毫米圆柱时绝对握力相似。患侧手与圆柱之间的接触面积减少了5%-9%。我们注意到接触面积与握力、明显萎缩和永久性感觉障碍之间存在高度相关性。对于所有圆柱尺寸，双手之间的负荷分布均存在显著差异。抓握大物体时，肘管综合征的主要功能障碍是拇指定位和稳定无力。抓握小物体时，手指固有肌无力是力量丧失的原因。 三、
