Implementation of interactive games to a shoulder rehabilitation and evaluation system

Abstract

BACKGROUND:

After an operation, the shoulder and wrist might not be able to lift and swing freely, and must be assisted with rehabilitation training.

OBJECTIVE:

In this paper, Kinect combined with multiple sensors of a Bluetooth ball is proposed to improve the measurement function of the arm’s micro-motion trajectory, rotation amount, and acceleration, which cannot be detected by Kinect alone.

METHODS:

We designed two virtual scene rehabilitation games for clinical trials. We performed validity analysis with a paired sample $t$ -test.

RESULTS:

A significance value of ${}^{*}P<$ 1 was obtained, and the arm lift angle shows an improvement from 30 ${}^{\circ }$ to 60 ${}^{\circ }$ , indicating that the range of motion of the hand and shoulder is gradually improving.

CONCLUSION:

Experiments show that virtual games combined with multiple sensors can better understand the patient’s rehabilitation situation.
