WebApr 11, 2024 · Step index (STEPIX) is a recently developed compound muscle action potential (CMAP) scan method for evaluating motor unit loss and remodeling changes. This study investigates the influence of different stimulation parameters during CMAP scan on STEPIX and its examination of muscles affected by spinal cord injury (SCI). WebMotor studies are performed by electrical stimulation of a nerve and recording the compound muscle action potential (CMAP) from surface electrodes overlying a muscle supplied by that nerve. The recording …

WebThe compound motor action potential (CMAP) which correlates with the number of functional axons is an indicator for axonal damage when significantly reduced. Because nerve conduction velocity (NCV) is sensitive to both myelin sheath and axonal changes, it is an excellent measure of the function of the peripheral nervous system.
