Method of gait evaluation and training with differential pressure system

An integrated differential air pressure and gait training system, comprising:

• a differential air pressure (DAP) unweighting system comprising a computer controller having a calibration routine to determine a user specific differential air pressure calibration factor;
• a gait measurement system in communication with the controller;
• an enclosure having a user seal adapted and configured to be positioned about a user while maintaining a pressure within the enclosure generated by the differential air pressure unweighting system;
• a treadmill within the enclosure positioned for access by the user when coupled to the user seal;
• at least one of a gait system sensor adapted and configured for communication with the gait measurement system wherein the at least one gait system sensor is on a user prosthesis, on a user exoskeleton, an instrumented article worn by the user or a marked article worn by a user;
• and
• a display in communication with the computer controller adapted and configured to provide real-time feedback from the gait measurement system to the user of the integrated differential air pressure and gait training system operated based on the user specific differential air pressure calibration factor.
