An embodiment of the invention resides in the apparatus and technique of dynamically measuring and storing a biological condition or disposition during the time that one set of conditions are imposed on a joint or body area and applying closed-loop therapeutic action so as to re-achieve that same biological condition or disposition during a subsequent time that another different set of conditions are imposed. Furthermore, dynamic potentials surrounding said joint or body area may be created, bolstered, and/or modulated through aspects of stimulation applied which are independent of those aspects utilized to counteract force incident on the joint or body area. Other embodiments are described herein.
