Document Type and Number:
WIPO Patent Application WO/1998/053740
Kind Code:
A1
Abstract:
A muscle tension monitor with preload controlling means comprises a hand supporting board for hand fixation, a pulsed constant current stimulator for stimulating the ulnar nerve to evoke the contraction of thumb musle, a force transducer for converting static tension and evoked contraction force in thumb muscle into electical signal, a preload controlling system for receiving said electrical signal and controlling said stimulator and preload controlling means, and preload controlling means for controlling the preload applied to the thumb. Said force transducer, stimulator, controlling system and preload controlling means are connected through a circuit to form a feedback control. With the muscle tension monitor, it is possible to control the preload to an optimum value automatically without the drawback of previous muscle tension monitor which need to adjust the preload manually and frequently.
