Abstract

A rehabilitation equipment includes a left foot pedal, a right foot pedal, a left-pedal driving module to drive movement of the left foot pedal, and a right-pedal driving module to drive movement of the right foot pedal. The rehabilitation equipment measures torques output by the left-pedal driving module and the right-pedal driving module when a user is at a relaxing state and also when the user is at an exercising state to obtain information relating to forces voluntarily output by the left foot and the right foot of the user, and determines a force output condition of the left foot and the right foot of the user.

First claim

What is claimed is:

1. A method for assessing voluntary movement of a user during rehabilitation, comprising steps of:
A) providing a rehabilitation equipment that includes:
a left foot pedal for operation by a left foot of the user;
a left-pedal driving module to drive movement of the left foot pedal for guiding the left foot of the user to take a step;
a left-pedal measuring module mounted to the left-pedal driving module and configured to measure a torque output by the left-pedal driving module to drive movement of the left foot pedal;
a right foot pedal for operation by a right foot of the user;
a right-pedal driving module to drive movement of the right foot pedal for guiding the right foot of the user to take a step;
a right-pedal measuring module mounted to the right-pedal driving module and configured to measure a torque output by the right-pedal driving module to drive movement of the right foot pedal; and
a processing module electrically coupled to the left-pedal measuring module and the right-pedal measuring module;

B) by the left-pedal measuring module and the right-pedal measuring module, measuring, during a first time period which has a length equaling that of a measuring cycle and in which both of the left foot of the user on the left foot pedal and the right foot of the user on the right foot pedal are at a relaxing state, the torque output by the left-pedal driving module to generate first left-pedal torque information corresponding to the first time period, and the torque output by the right-pedal driving module to generate first right-pedal torque information corresponding to the first time period,
