Older adults walk with a shorter stride length, reduced hip range of motion (ROM) and higher cadence. These are signs of reductions in walking ability. This study investigated whether using a wireless smart insole system that monitored and provided biofeedback to encourage an extension of swing time could increase stride length and hip flexion, while reducing the cadence. Seven older adults were tested in this study, with and without the biofeedback device, in an outdoor environment. Gait analysis was performed by using GaitRite system and Xsens MVN. Repeated measures analysis demonstrated that with biofeedback, the swing time increased by 6.45%, stride length by 4.52% and hip flexion by 14.73%, with statistical significance. It also decreased the cadence significantly by 5.5%. This study has demonstrated that this smart insole system modified positively the studied gait parameters in older adults and has the potential to improve their walking ability.
老年人走路步幅较短，髋关节活动范围（ROM）减小，步频较高。这些都是步行能力下降的迹象。本研究调查了使用无线智能鞋垫系统监测并提供生物反馈以鼓励延长摆动时间是否能增加步幅和髋关节屈曲度，同时降低步频。本研究对7名老年人在户外环境中进行了测试，测试时使用和不使用生物反馈装置。通过GaitRite系统和Xsens MVN进行步态分析。重复测量分析表明，使用生物反馈时，摆动时间增加了6.45%，步幅增加了4.52%，髋关节屈曲度增加了14.73%，具有统计学意义。步频也显著降低了5.5%。本研究表明，这种智能鞋垫系统能积极改善老年人的步态参数，具有提高他们步行能力的潜力。
