Abstract: Some embodiments include a system with a sensor with electrodes including an active electrode and a receiving electrode that is in physical contact with skin of a patient forming an electrical circuit with control electronics of a controller that can measure an electrical parameter using an active electrode and a receiving electrode within a closed loop electrical muscle stimulation system. A sense electrical pulse can be applied to the tissue using the sensor, an electrical parameter measured from the tissue, and a stimulation pulse applied to the tissue based at least in part on the measured electrical parameter. The stimulation is adjustably controlled by the controller to maintain a constant power output to the tissue based on the electrical parameter. A good is coupled to a computer readable medium configured to store usage data, the usage data relating to the patient's use of the good.

Abstract: Disclosed is a system including a good comprising a sensor in contact with human tissues of a patient and configured to obtain a power dissipation reading of the human tissues. The good also includes a storage medium for tangibly storing thereon a program for execution by a processor. The system also includes a control unit in communication with the good to form an electrical muscular stimulation (EMS) system that uses feedback in a closed loop manner to self tune electrical properties of the output. The control unit is configured to instruct the sensor to (a) apply a sense pulse to the human tissues, (b) measure power dissipation of the sense pulse, (c) adjust a stimulation pulse based on the measured power dissipation, (d) apply the stimulation pulse to the human tissues based on the power dissipation and based on the program in order to maintain constant power output across each pulse, and (e) repeat steps (a)-(d).
