A phase oscillating device for affecting movement of a limb or a primary body includes a sensor coupled to the primary body. A physical state of the primary body is measured using the sensor. A phase angle of the primary body is determined based on the physical state measurement. The physical state measurement includes position, velocity, or acceleration. The phase angle of the primary body is filtered using a sine function. An actuator is coupled to the primary body. The actuator is triggered based on the phase angle of the primary body to provide a force or torque to assist or resist movement of the primary body. A secondary body is coupled to the primary body. The secondary body is oscillated using the actuator, which is triggered in phase with a gait step. Alternatively, a fan is coupled to the primary body and actuator to provide the oscillating force.

Systems and methods for adding or subtracting energy to body motion

A system and method for controlling a prosthetic limb are provided. A sensor component receives input from a wearer's muscle and provides a signal to a control component. The sensor component may be a force sensing resistor placed inside a socket of a prosthetic limb between a residual limb and the hard side of the socket. The control component processes the signal and provides instructions to an actuation component. In this manner, an actuation component may move a joint, or may change the velocity of a joint, or may change other characteristics of the prosthetic limb.
