Device and method for gait synchronized sensory stimulation of the lower extremities

A method comprising:

• compressing a trigger chamber, the trigger chamber having a trigger elastic wall and a trigger base wall, the trigger chamber configured for relative motion between the trigger elastic wall and the trigger base wall;
• forcing fluid through a connecting line, the connecting line fluidly coupled to the trigger chamber, the connecting line having a substantially inelastic wall;
• expanding a stimulation chamber fluidly coupled to the connecting line, the stimulation chamber having a stimulation elastic wall and a stimulation base wall, the stimulation chamber configured for relative motion between the stimulation elastic wall and the stimulation base wall, the stimulation elastic wall having an exterior surface, wherein expanding the stimulation chamber causes a plurality of projections to contact a user, the plurality of projections coupled to the exterior surface;
• and
• extending a projection through an aperture in a stabilizing frame, the stabilizing frame covering the stimulation chamber, the stabilizing frame having a substantially rigid wall.
