1. A method of monitoring a gait of a person, said method comprising:
placing a gait-altering device on at least one foot of a person;
attaching a transferable housing to the gait-altering device, wherein the transferable housing contains all of a plurality of wireless sensors that monitor a gait of the person;
obtaining, using the plurality of wireless sensors of the transferable housing that monitor a gait of the person, first sensor data while the person is wearing the gait-altering device;
transforming the first sensor data obtained from the plurality of wireless sensors into one or more of first gait parameters wherein the one or more of first gait parameters includes one or more of gait cycle duration, gait cadence, stride length, stride velocity, turning angle, stance, swing, loading, foot flat, pushing, double support, peak angular velocity, swing speed, strike angle, lift-off angle, swing width, 3D path length, maximum heel clearance, maximum toe clearance (foot with toes angled downward), minimum toe clearance, and second maximum toe clearance (foot with toes angled downward) while the person is wearing the gait-altering device;
removing the gait-altering device from the at least one foot of the person;
removing the transferable housing from the gait-altering device and attaching the transferable housing to the at least one foot of the person;
obtaining, using the plurality of wireless sensors of the transferable housing that monitor the gait of the person, second sensor data while the person is not wearing the gait-altering device and has the transferable housing attached to the at least one foot;
transforming the second sensor data obtained from the plurality of wireless sensors into one or more of second gait parameters wherein the one or more of second gait parameters includes one or more of gait cycle duration, gait cadence, stride length, stride velocity, turning angle, stance, swing, loading, foot flat, pushing, double support, peak angular velocity, swing speed, strike angle, lift-off angle, swing width, 3D path length, maximum heel clearance, maximum toe clearance (foot with toes angled downward), minimum toe clearance, and second maximum toe clearance (foot with toes angled downward) while the person is not wearing the gait-altering device;
analyzing, by one or more processors, at least a portion of the first gait parameters and the second gait parameters, wherein the analyzing at least comprises comparing at least a portion of the first gait parameters and the second gait parameters; and
determining, by the one or more processors, based on the analysis, a treatment plan and/or a modification of an existing treatment plan for the person involving use of the gait-altering device,
wherein the gait-altering device comprises a gait-altering shoe comprising a frame adapted to support the at least one foot of the person; and at least one wheel that supports the frame above a walking surface, the wheel having a radius that varies as a function of angular position of the wheel such that the wheel automatically rotates when weight is applied to the shoe.
