Abstract

A gait training system using motion analysis is provided to perform consecutive motion analysis while a person to be measured is walking on a treadmill. The gait training system includes a treadmill including a belt rotatable by a roller of which a rotating rate is adjustable in response to a walking speed of a walker; and measuring means for transferring signals associated with a movement of a body of the walker. The measuring means are attached to the body. A control unit analyzes a walking movement based on a data from the measuring means, and a display unit displays the data to the walker.

Claims

1. A gait training system, the system comprising:

a treadmill having a belt rotatable by a roller wherein a rotating rate of the roller is adjustable in response to a walking speed of a walker;

measuring means for transferring signals associated with a movement of a body of the walker wherein the measuring means is attached to the body;

a control unit for analyzing a walking movement of the walker based on a data from the measuring means; and

a display unit for displaying the data to the walker.

2. The gait training system of claim 1 further comprising:

a marker attached to a lower limb of the walker wherein the marker captures a motion and further wherein the measuring means has a camera arranged adjacent to the treadmill wherein the camera locates the marker wherein the camera detects a walking movement of the walker on the treadmill.

3. The gait training system of claim 1 further comprising:

an electric goniometer;

wherein the electric goniometer has a flexible bar for bending in response to a bending of a lower limb joint of the walker and further wherein the electric goniometer has an attachment support for securing the flexible bar to a lower limb of the walker.

4. The gait training system of claim 1 further comprising:

a goniometer;

wherein the goniometer has a variable resistor with a resistance value that varies according to an angle of a joint and further wherein the goniometer has an attachment support for securing the variable resistor to a lower limb of the walker.

5. The gait training system of claim 1 further comprising:

a sensor arranged in a position lateral to the belt wherein the sensor has piezoelectric devices arranged with a gap on an upper surface of the sensor.

6. The gait training system of claim 5 wherein the sensor:

has a first sensor arranged in a front portion of the treadmill wherein the first sensor detects an accelerated movement and a relocation of the walker and further wherein the sensor has a second sensor arranged in a rear portion of the treadmill wherein the second sensor detects a decelerated movement and the relocation of the walker.

7. The gait training system of claim 1 further comprising:

a pair of piezoelectric plates arranged in a bottom surface of the treadmill wherein the piezoelectric plates measure a time that a lower limb of the walker touches the bottom surface of the treadmill.
