背景：这项研究的目的是确定一些关键因素，这些因素的神经肌肉骨骼系统的功能随年龄的变化可能与维持站立平衡有关。方法：共测试了38名健康受试者(年龄范围为21-77岁)。提供了足部姿势障碍，并检查了头部、躯干、大腿、小腿和脚的活动范围。测试了三种支撑面：硬的、软的和缩小的。在每个受试者中评估的功能包括一般健康、触摸和四个不同位置的皮肤振动知觉阈值、脚踝力量和活动范围。这些功能与身体最大运动幅度相关。结果：在足部所有四个位置的皮肤振动知觉阈值、足底屈肌力量和脚后跟区域的触摸感觉都有显著的年龄相关性变化。无论平台的支撑面和运动方向如何，年龄与头部运动均呈正相关。屈肌力量也与头部运动相关，但仅当平台向后移动时。当站在较大的支撑基座上时，第5跖头的皮肤振动知觉阈值随年龄的变化对头部运动的影响比其他区域的皮肤振动知觉阈值的影响更大，但更小。结论直立平衡的稳定，尤其是头部，与年龄、足底屈肌力量和脚部的振动感觉有关。这项研究中的实验室测试确定了这种相关性。
Background.The purpose of this study was to identify some critical factors whose functional changes with age in the neuromusculoskeletal systems would potentially relate to the maintenance of standing balance.Methods.A total of 38 healthy subjects were tested (age range, 21–77 years). A postural disturbance at the foot was provided, and the range of movement of the head, trunk, thigh, shank, and foot was examined. Three supporting surfaces were tested: hard, soft, and reduced. The functions evaluated in each subject included general health, touch, and cutaneous vibratory perception threshold at four different locations, ankle strength, and range of motion. The functions were then correlated with the maximum magnitude of the body movement.Results.There were significant age-related changes in cutaneous vibratory perception threshold at all four locations of the foot, in plantarflexor strength, and in touch sensation at the heel region. Age had a positive correlation with head movement regardless of the supporting surface and the movement direction of the platform. Plantarflexor strength was also correlated with head movement but only when the platform moved in the backward direction. When standing on a large supporting base the change in cutaneous vibratory perception threshold at the 5th metatarsal head with respect to age showed a larger, although weak, effect on the head movement than the cutaneous vibratory perception threshold at other regions.Conclusions.The stabilization of an upright balance, especially the head, was related to age, plantarflexor strength, and vibratory perception at the foot. The laboratory test in this study identified such correlations.
