【摘要】：目的:探讨不同肌力输出情况下,手指力量觉所反映的规律及机制。方法:对30名男大学生进行优势侧各手指最大等长肌力测试和不同肌力的力量重现法测试。结果:各手指力量觉由好到差依次是食指、拇指、中指、无名指、小指。不同肌力时力量觉曲线呈U型,两端高,中间低。当肌力较小时,实测值较目标力值大;当肌力适中时,实测值较目标力值差异不大;当肌力较大时,实测值较目标力值小。结论:精细动作的力量感知主要由食指和拇指完成,中指起主要的辅助作用,无名指和小指起次要的辅助作用。肌力较大或较小时,力量觉都较差,而肌力大小适中时力量觉较好。当肌力较小时,实际输出的力量比自我感觉的力值大;当肌力适中时,实际输出的力量和自我感觉的力值较接近;当肌力较大时,实际输出的力量比自我感觉的力值小。
[Abstract]:Aim: to investigate the mechanism of finger force perception under different muscle output.Methods: 30 male college students were tested for the maximum isometric muscle strength of each finger on the dominant side and the strength reconstruction method for different muscle strength.Results: the index finger, thumb, middle finger, ring finger and little finger were the best to the worse.At different muscle strength, the curve of force perception was U-shaped, high at both ends and low in middle.When the muscle force is small, the measured value is larger than the target force value; when the muscle force is moderate, the measured value is not different from the target force value; when the muscle force is large, the measured value is smaller than the target force value.Conclusion: the power perception of fine movement is mainly accomplished by the index finger and thumb, the middle finger plays a major auxiliary role, and the ring finger and the small finger play a secondary auxiliary role.When the muscle strength is larger or smaller, the sense of strength is worse, and when the muscle strength is moderate, the sense of strength is better.When the muscle strength is small, the actual output strength is larger than the self-feeling force; when the muscle force is moderate, the actual output strength and the self-feeling force value are close; when the muscle force is larger, the actual output strength is smaller than the self-feeling force value.
