Strength-duration relationship for extracellular neural stimulation: numerical and analytical models.

abstract：:Skeletal muscle force can be transmitted to the skeleton, not only via its tendons of origin and insertion but also through connective tissues linking the muscle belly to surrounding structures. Through such epimuscular myofascial connections, length changes of a muscle may cause length changes within an adjacent musc...
