Experimental Research of Range of Motion About Wrist Joint
Objective: To investigate the range of motion (ROM) of wrist joint in human body, and the difference about ROMs between man and woman in subgroups and how it relates to age itself;
Methods: One hundred healthy and no movement disorders volunteers from 18–60 years old were recruited to complete the study. They were divided into 2 groups, and half of them are male. The VICON motion capture system was used to measure ROMs of wrist joint. The average value of wrist joint ROMs for each age groups were calculated; The change in the ROM for each age group was compared; The difference in the ROM between male and female was compared, and the difference in the ROMs of wrist joint on the left and right was compared too.
Results: ROMs of wrist palmar flexion and dorsiflexion decreased with the increasing of the age. The difference about ROMs in groups was not significant. Conclusion: The ROMs of wrist palmar flexion and dorsiflexion for normal human decreased with the increasing of the age, but the difference in groups was small.
