1. A system, comprising:

  • a first system including;

    a deformable substrate configured to interface with a skin surface of a first body portion;

    a sensor assembly coupled to the deformable substrate, the sensor assembly including a motion sensor and a physiological sensor, the motion sensor including a proximity sensor configured to detect a movement of the first body portion relative to a second body portion proximate the first body portion, the sensor assembly configured to generate one or more sense signals based on detection of the movement of the first body portion relative to the second body portion by the proximity sensor and a physiological parameter of the first body portion by the physiological sensor;

    a processor operably coupled to the sensor assembly and configured to receive the one or more sense signals, the processor configured to compare the one or more sense signals to a threshold duration and to determine whether the first body portion is held in a position for a duration longer than the threshold duration; and

    an effector operably coupled to the processor and configured to affect the first body portion responsive to control by the processor, the effector including a nerve stimulator configured to affect a nerve proximate to the first body portion responsive to control by the processor when the first body portion is determined to be held in the position for the duration longer than the threshold duration;

    a second system including;

    a second deformable substrate configured to interface with a second skin surface;

    a second sensor assembly coupled to the second deformable substrate, the second sensor assembly including a second motion sensor and a second physiological sensor, the second sensor assembly configured to generate one or more sense signals based on detection of a movement of a third body portion by the second motion sensor of the second sensor assembly and a physiological parameter of the third body portion by the second physiological sensor of the second sensor assembly;

    a second processor operably coupled to the second sensor assembly and configured to receive the one or more sense signals of the second sensor assembly; and

    a second effector operably coupled to the second processor and configured to affect the third body portion responsive to control by the second processor; and

    a communications interface between the first system and the second system, wherein the first system and the second system are configured to provide one or more communication signals to the respective other of the first system and the second system via the communications interface.
