Disclosed are prosthetic systems comprising a powered knee prosthesis and a volitional controller configured to provide control of the prosthesis to the user. The prosthetic system may be configured to enable a user to walk on smooth and / or uneven terrain and to ascend and / or descend stairs. The volitional controller may be configured in a contact state when the prosthesis is in contact with a ground surface and a no contact state when the prosthesis is lifted from the ground surface. When in the contact state, the controller may output a knee torque signal for controlling the powered knee of the prosthesis. The knee torque signal may be based on a target knee torque determined by the knee orientation and the torque measured at the ankle of a prosthetic foot. When in the no contact state, the controller may output a knee torque signal based on a desired knee position.

An adaptive stimulation system optimizes pain relief, pleasure enhancement, and healing through closed-loop physiological effectiveness monitoring. The system comprises a stimulation device, sensors measuring physiological responses indicative of stimulation effectiveness, and a processor implementing real-time adaptive control. The system measures unconscious physiological responses that users cannot voluntarily control and involuntary reactions to objectively assess whether stimulation achieves desired outcomes. Through proxy learning, system sensors correlate with sophisticated clinical measurements via machine learning, enabling clinical-grade optimization using accessible devices. The system continuously explores multidimensional parameter spaces to discover optimal stimulation patterns personalized to individual users, automatically adapting parameters based on measured physiological effectiveness rather than subjective user control or preset patterns. Applications include medical devices, wellness products, and intimate stimulation systems.
