Innovative device enhances joint range of motion in elderly care, suggesting improved rehabilitation outcomes.

The primary aim is to develop an assistive device to improve the range of motion for knee and hip joints in elderly patients.
Developed a passive motion support device using pneumatic soft actuators.
Actuators were optimized in placement and structural design, positioned on the lateral thigh.
Conducted experimental evaluations to measure joint range of motion performance.
The device achieved over 95% of active range of motion in the knee.
The device achieved over 85% of active range of motion in the hip.
The performance indicated a need for further refinement in hip flexion to reach target range of motion.

TANIGUCHI et al. (2025) studied this question.
