Purpose
To investigate the characteristics of balance and gait functions in Generalized Joint Hypermobility (GJH) subjects residing in high-altitude areas.
Methods
This study included 61 university students (28 with GJH and 33 healthy controls) all from the high-altitude region of Linzhi, Tibet Autonomous Region. The Riablo™ wearable intelligent rehabilitation assessment and training system was used to assess static balance (with eyes open and closed) and gait function (during flat walking) in both groups.
Results
Compared to healthy subjects, GJH subjects exhibited significantly impaired balance, indicated by an increased distance of the center of pressure position from the ideal center of gravity(EO:
P
= 0.007, EC:
P
= 0.031) and greater amplitude of center of pressure displacements (EO:
P
= 0.043, EC:
P
= 0.032). Gait velocity(
P
= 0.007), stride length(
P
= 0.012), and swing stance phase of the gait cycle(
P
= 0.046) were significantly reduced in GJH subjects compared to healthy subjects. A significant increase in the flat-foot phase of the gait cycle(
P
= 0.022) was observed in GJH subjects compared to healthy subjects.
Conclusion
The current study demonstrated that GJH subjects residing in high-altitude areas exhibit impairments in balance and gait, providing a basis for training and prevention strategies tailored for this population. And this study used the wearable intelligent rehabilitation evaluation and training system in high-altitude areas, providing methodological references for scientific research on balance and gait function under non laboratory conditions.
