Testing of a Wearable Upper-Arm Assist Robot

Basic Information

Recruitment status	Pending
Health condition(s) or Problem(s) studied	None
Date of first enrollment	17/12/2025
Target sample size	10
Countries of recruitment
Study type	Interventional
Intervention(s)	First, the robot is attached to the upper arm of the wearer. After the robot is attached, the operator grasps the wearer's upper arm and performs one to three reciprocating movements within the range of motion of the shoulder joint and scapula or part thereof (teaching mode). At this time, the robot records the data of the rehabilitation movement in the form of motor angles. The robot then moves the subject's upper arm without operator assistance while the device is attached to the upper arm in a manner that reproduces the rehabilitation movements recorded by the robot (playback mode). The recorded and actual motor angle data in the two modes are compared to evaluate the reproducibility and accuracy of the rehabilitation movements in the playback mode.

Outcome(s)

Primary Outcome	Agreement of subject's shoulder motion data between teaching mode with rehabilitation assistant and playback mode without rehabilitation assistant in simulated rehabilitation
Secondary Outcome	None
