本研究探讨了各种临床措施和性能的功能精度抓举任务之间的关系。15名8至14岁的偏瘫性脑瘫（CP）儿童和15名年龄匹配的对照儿童抓住并举起表面纹理不同的物体，同时记录他们的指尖力。采用相关和回归分析，将力的协调性与触觉、握力、手的灵活性和痉挛状态进行比较。研究结果强调了触觉在这项任务中的重要性。然而，灵敏度相关的方式不同的指尖力的感觉适应，力的增加的预期缩放，以及包括抓举任务的时间阶段之间的平稳过渡。研究结果还表明，痉挛影响任务的某些措施，但不是其他人，这表明痉挛和运动性能之间的关系可能不是绝对的。研究结果进一步表明，偏瘫CP儿童抓握障碍主要是但不完全是由于感觉机制紊乱，这可能对治疗干预有直接影响。
The present investigation examines the relation between various clinical measures and the performance of a functional precision grip-lift task. Fifteen children with hemiplegic cerebral palsy (CP), aged 8 to 14 years, and 15 age-matched control children grasped and lifted an object whose surface texture was varied while their fingertip forces were recorded. The force coordination was compared with tactile sensibility, grip strength, manual dexterity, and spasticity using correlational and regression analyses. The findings highlight the importance of tactile sensibility in this task. However, the manner in which sensibility was related varied for the sensory adaptation of fingertip forces, the anticipatory scaling of the force increase, and the smooth transitions between the temporal phases comprising the grip-lift task. The findings also indicate that spasticity affects some measures of the task, but not others, suggesting that the relation between spasticity and motor performance may not be absolute. The results further suggest that the impairments in grasping in children with hemiplegic CP are largely but not exclusively due to disturbed sensory mechanisms which may have direct implications for therapeutic intervention.
