Appl. No.:

14/565792

International Classification:

A63B 24/00
A63B 22/02

Abstract:

This gait analysis apparatus comprises three, and preferably four, vertical force sensors disposed between a treadmill and the ground. When a person walks on the treadmill belt, each force sensor emits an electronic signal proportional to the load on the frame. The sensors measure the load hundreds of times per second and that data, in combination with the speed of the treadmill belt, enables a processing unit to calculate many gait parameters. The resultant calculations are displayed to the clinician in numeric and graphical formats. Due largely to the few number of force sensors, the apparatus is relatively inexpensive compared to existing gait parameter apparatuses and can be easily retrofitted to existing treadmills by either replacing the treadmill's existing ground supports with force sensors or resting the treadmill on top of a frame that has integral force sensors.

Abstract:

A lightweight treadmill for walking which utilizes a short walking surface, a small and lightweight motor, strong but minimized frame design; and a remote display to make a compact, relatively lightweight and portable treadmill. In the preferred embodiment the treadmill uses. In the preferred embodiment a servomotor and pulley system to generate high-torque, thereby enabling walking at very slow speeds. The servomotor and pulley system fit within the low-profile treadmill base, eliminating the need for a housing at the front end of the treadmill. A walker may be attached to the treadmill for increased stability while walking.
