To investigate the effect of a 16-week Tai Chi practice on strength, tactile sensation, kinesthesia, and static postural control among older adults of different age groups.
This is a quasi-experimental study. Thirteen participants aged 60-69 years (60-69yr), 11 aged 70-79 years (70-79yr), and 13 aged 80-89 years (80-89yr) completed 16 weeks of 24-form Tai Chi practice. Their ankle and hip peak torque, tactile sensation, ankle and knee kinesthesia, and the root mean square of the center of pressure (Cop-RMS) were measured before (week 0) and after (week 17) practice.
80-89yr showed less ankle plantar/dorsiflexion and hip abduction peak torques (p = 0.003, p < 0.001, p = 0.001), and a greater ankle plantar/dorsiflexion kinesthesia (p < 0.001, p = 0.002) than 60-69yr and 70-79yr. Greater ankle plantar/dorsiflexion and hip abduction torques (p = 0.011, p < 0.001, p = 0.045), improved arch and heel tactile sensation (p = 0.040, p = 0.009), and lower knee flexion/extension kinesthesia (p < 0.001, p = 0.044) were observed at week 17. The significant group*practice interaction for the fifth metatarsal head tactile sensation (p = 0.027), ankle plantar/dorsiflexion kinesthesia (p < 0.001, p = 0.004), and the CoP-RMS in the mediolateral direction (p = 0.047) only in 80-89yr revealed greater improvement at week 17.
Tai Chi practice increased strength, tactile sensation, kinesthesia, and static postural control among older adults. Tai Chi practice improved tactile, kinesthesia sensations, and static postural control among older adults over 80, who presented with worse strength and kinesthesia than their younger counterparts. Tai Chi practice offers a safe exercise option for those aged over 80 to encourage improvements in sensorimotor control.
探讨为期16周的太极拳练习对不同年龄组老年人的力量、触觉、动觉和静态姿势控制的影响。
这是一项准实验研究。13名60 - 69岁（60 - 69岁组）、11名70 - 79岁（70 - 79岁组）和13名80 - 89岁（80 - 89岁组）的参与者完成了16周的24式太极拳练习。在练习前（第0周）和练习后（第17周）测量他们的踝关节和髋关节峰值扭矩、触觉、踝关节和膝关节动觉以及压力中心的均方根（Cop - RMS）。
与60 - 69岁组和70 - 79岁组相比，80 - 89岁组的踝关节跖屈/背屈和髋关节外展峰值扭矩较小（p = 0.003，p < 0.001，p = 0.001），踝关节跖屈/背动动觉更大（p < 0.001，p = 0.002）。在第17周观察到更大的踝关节跖屈/背屈和髋关节外展扭矩（p = 0.011，p < 0.001，p = 0.045）、足弓和足跟触觉改善（p = 0.040，p = 0.009）以及膝关节屈伸动觉降低（p < 0.001，p = 0.044）。仅在80 - 89岁组中，第五跖骨头触觉（p = 0.027）、踝关节跖屈/背动动觉（p < 0.001，p = 0.004）和内外侧方向的Cop - RMS（p = 0.047）的显著组*练习交互作用显示在第17周有更大改善。
太极拳练习增强了老年人的力量、触觉、动觉和静态姿势控制。太极拳练习改善了80岁以上老年人的触觉、动觉和静态姿势控制，这些老年人的力量和动觉比年轻同龄人差。太极拳练习为80岁以上的人提供了一种安全的运动选择，以促进感觉运动控制的改善。
