Abstract
Gait analysis systems are provided with body support systems for user's self-adjustment of body weight force when ambulating with the body support systems. The gait analysis systems with the body support systems can be used with a treadmill or over a fixed surface for gait training and analysis with the ability to adjust the user's body weight force during the collection of gait data. Gait data for analysis is collected by an array of sensors mounted on the body support systems in various combinations for sensing gait movement, video imaging, heel strike and toe off states, video processing, feet pressure maps and electromyography.
Claims21
A gait analysis system for a body support system with provisions for a user self-adjustment of a user's body weight force during ambulation when a user is on the body support system, the gait analysis system comprising:
- a gait measurement system connected to the body support system, the gait measurement system comprising:
- a forward gait measurement sensor;
- a vertical gait measurement sensor;
- and
- at least one visual sensor;
- a system gait sensors integrator for receiving a plurality of gait sensor signals, the plurality of gait sensor signals comprising at least:
- a forward gait measurement sensor output signal from the forward gait measurement sensor comprising a forward rotary encoder, the forward rotary encoder having a forward rotary encoder output shaft, the forward rotary encoder output shaft connected to a wheel-driven axle of a forward wheel making contact with a treadmill surface that rotates in a forward direction with user ambulation on the body support system over the treadmill surface whereby a forward rotary encoder output signal comprises the forward gait measurement sensor output signal and provides a real time forward user movement data simulated by a forward movement of the treadmill surface making contact with the treadmill surface;
- a vertical gait measurement sensor output signal from the vertical gait measurement sensor comprising a vertical rotary encoder, the vertical rotary encoder having a vertical rotary encoder output shaft, the vertical rotary encoder mounted on the body support system, the vertical rotary encoder output shaft connected to a vertical rotational element of the body support system that rotates in a vertical direction with user ambulation on the body support system over the treadmill surface whereby a vertical rotary encoder output signal comprises the vertical gait measurement sensor output signal and provides a real time vertical user movement data proportional to the rotation of the vertical rotational element;
- and
- a user video sensor output signal from the at least one visual sensor.
