Methods and apparatus for body weight support system

A method, comprising:

• receiving, at a trolley, electrical current from a rigid power conductor, the trolley including a drive configured to movably couple the trolley to a stationary support track and a support coupled to a tether configured to support at least a portion of a weight of a user, the rigid power conductor being fixedly coupled to and offset from the stationary support track;
• directing a first flow of the electrical current to the support to move a portion of the tether in response to movement of the user;
• directing a second flow of the electrical current to the drive to move the trolley along the stationary support track in response to the movement of the user;
• receiving, from a first sensor, a first signal associated with an operating condition of the support after the directing of the first flow of the electrical current;
• receiving, from a second sensor, a second signal associated with an operating condition of the drive after the directing of the second flow of the electrical current;
• identifying at least one gait characteristic associated with the movement of the user based at least in part on the operating condition of the support and the operating condition of the drive wherein the at least one gait characteristic includes symmetry between steps taken by the user with the user's left leg and right leg;
• and
• sending, to an electronic device having a display, a third signal associated with an instruction to output data associated with the at least one gait characteristic via the display.

A method, comprising:

• receiving, at a trolley, electrical current from a rigid power conductor, the trolley including a drive configured to movably couple the trolley to a stationary support track and a support having a tether configured to support at least a portion of a weight of a user, the rigid power conductor being fixedly coupled to and offset from the stationary support track such that each of the stationary support track and the drive are separated from the rigid power conductor;
• receiving signals associated with a plurality of operating conditions of the trolley;
• directing, in response to a change in force exerted by the user on the tether, a flow of electrical current to at least one of the drive or the support to transition the trolley between the plurality of operating conditions, the drive being configured to move the trolley along the stationary support track in response to the flow of electrical current, the support being configured to move a portion of the tether relative to the user in response to the flow of electrical current;
• identifying at least one gait characteristic of the user based at least in part on a difference between operating conditions of the trolley wherein the at least one gait characteristic includes symmetry between steps taken by the user with the user's left leg and right leg;
• and
• displaying data associated with the at least one gait characteristic of the user on a display of an electronic device in communication with the trolley.
