Many of the aches and pains of adults are the result of the long-term effects of bad posture or body misalignment. Postural kyphosis in adolescence, which is an excessive rounding of the upper spine, may be one of the effects of poor standing and sitting habits. A smart garment, consisting of a harness and two data-sensor loggers, was developed to monitor and provide vibration feedback to wearers to improve their posture during daily activities. Laboratory tests verified that the garment could provide an accuracy of 2 ± 2° during static measurement and 3 ± 2° during stable or slowly changing posture activities and 4 ± 4° during rapidly changing posture activities. Four volunteers wore the system for 3 h per day and for 4 consecutive days. The feedback was provided on the last 2 days and the kyphotic angle reduced by 8 ± 1° and 8 ± 2° on the last 2 days, respectively. Although the long-term effects of reminding the subjects' posture is still not clear, a short-term result shows promise that the smart garment may be able to improve the kyphosis.
许多成年人的疼痛是长期不良姿势或身体错位的结果。青少年时期的姿势性后凸，即上脊柱过度弯曲，可能是不良站立和坐姿习惯的影响之一。一种由背带和两个数据传感器记录器组成的智能服装被开发出来，以监测和向佩戴者提供振动反馈，从而改善他们在日常活动中的姿势。实验室测试验证了该服装在静态测量时可以提供 2±2°的精度，在稳定或缓慢变化的姿势活动中可以提供 3±2°的精度，在快速变化的姿势活动中可以提供 4±4°的精度。四名志愿者每天佩戴该系统 3 小时，连续佩戴 4 天。在最后两天提供反馈，最后两天的后凸角度分别减少了 8±1°和 8±2°。尽管提醒受试者保持正确姿势的长期效果尚不清楚，但短期结果表明，智能服装可能能够改善后凸。
