【摘要】：目的探究年龄、性别的差异对正常人坐站转移髋关节及足底压力运动学参数的影响。方法比较正常成人在从坐到站过程中不同时期的髋关节运动学参数如关节角度变化、运动速度、时间等及足底压力变化如压力、压强、接触面积等，分别比较性别及年龄作为变量下的各个参数的差异。将符合标准的受试者151人分别按照年龄分为青年组（20-39岁）、中年组（40-59岁）和老年组（60-79岁），按照性别分为男性和女性两组；使用由中科院合肥研究院智能所研发的足底压力测量设备（型号： JPD4050，厂家：安徽君诚体育器械有限公司）和生物信号采集系统（型号：BioDAQ-32型，中科院合肥研究院智能所），足底压力测量设备用来测量坐站转移过程中的足底压力变化，生物信号采集系统用来测量坐站转移过程中的关节角度变化。结果 ①髋关节运动学参数：在坐站转移过程中的I期角度男性大于女性，差异有统计学意义（P0.05），躯干I期速度及III期速度男性大于女性，差异有统计学意义（P0.01）。青年组及中年组的I期角度及所用时间明显小于老年组，差异具有统计学意义（P0.01），青年组的坐站转移速度较中年组和老年组快，差异有统计学意义（P分别小于0.01和0.05），坐站转移的总时间老年组明显均大于青年组和中年组，，差异均有统计学意义（P0.01）②足底压力参数：在坐站转移的整个过程，男性的单位面积足底压力明显高于女性，差异有统计学意义（P0.01）；在转移末期女性的足-地间的接触面积增加明显大于男性，差异具有统计学意义（P0.05）。I期初始压强及结束压强青年组及中年组明显高于老年组，差异均有统计学意义（P0.01），III期结束压强青年组及中年组均高于老年组，差异有统计学意义（P分别小于0.05及0.01），III期面积变化比青年组小于中年组和老年组（P分别小于0.05和0.01），中年组小于老年组，差异有统计学意义（P0.05）结论在无辅助下坐站转移时男性主要靠增加转移速度、女性依靠增加足-地间的接触面积来完成动作；同样青年人及中年人主要靠增加转移速度、老年人主要靠增加足-地间的接触面积来保证动作的完成，年龄、性别可影响坐站转移的完成。
[Abstract]:Purpose

To investigate the effects of age and sex on kinematics parameters of hip and plantar pressure in normal subjects .

method

The differences between sex and age were compared with those of normal adults ( 20 - 39 years ) , middle - aged group ( 40 - 59 years ) and old group ( 60 - 79 years ) .
The plantar pressure measuring equipment ( model : JPD4050 , manufacturer : Anhui Juncheng Sports Equipment Co . , Ltd . ) and the biological signal acquisition system ( model : Biosensors - 32 , Intelligent Institute of Hefei Institute of Chinese Academy of Sciences ) were used to measure the change of plantar pressure during the transit of the sitting - station , and the biological signal acquisition system was used to measure the joint angle change during the transit .

Results

There was significant difference between the two groups ( P0.01 ) . The difference was statistically significant ( P0.01 ) . There was significant difference between the young group and middle age group ( P0.01 ) .
There was significant difference in the contact area between the middle - aged group and middle - aged group ( P < 0.05 ) . The difference was statistically significant ( P < 0.05 and 0.01 ) . The difference was statistically significant ( P < 0.05 ) .

Conclusion

In the absence of secondary transfer , the male mainly depends on increasing the transfer speed , and the female relies on increasing the contact area between feet and ground to complete the action ;
In the same way , young people and middle - aged people rely mainly on increasing the transfer speed , and the elderly mainly rely on increasing the contact area between feet and ground to ensure the completion of the action , and the age and sex can affect the completion of the transfer of the seat station .
