UD is effective and useful at practice situation, since the dynamic visual feedback of the muscle contraction allows to easily and reliably locate the electrode location over the target muscle.<br>Diagnostic ultrasound should also be a good visual feedback system to train or detect proper signal strength from limb deficiency patients.</p> ER -
