Embodiment Construction

[0038] The present invention will be described in detail below with reference to the accompanying drawings.

[0039] figure 1 It is a schematic diagram of the structure of the functional electrical stimulation system (FES) of the present invention. The functional electrical stimulation system of the present invention includes three basic parts: a hand rest 100 , a portable host 110 and a finger sensor 150 . In addition, the FES system can interact with a PDA 190 or a computer PC (not shown in the figure) to realize parameter setting of the system. The functional electrical stimulation system has two basic configurations. In a first configuration, the FES system can be initially set up and configured with parameters. In the second configuration, the portable host 110 operates in a stand-alone mode and is not connected to the PDA 190 and computer.

[0040] Please refer to Figure 2 to Figure 5, the hand rest 100 is molded from a plastic material, and is adapted to the shape...

Abstract

The present invention discloses one kind of functional electric stimulation system for rehabilitation of upper limbs of apoplexy patient. The functional electric stimulation system includes one arm support for supporting the upper limbs of the patient and with electrodes for electric stimulation; one finger sensor for being worn onto the finger of the patient to sense the motion of the finger; one portable system unit connected to the electrodes and the finger sensor for controlling the electric stimulation based on the sensed signal.

Description

technical field [0001] The present invention relates to a medical appliance for rehabilitation, in particular to a functional electrical stimulation system, which is used to restore the motor functions of upper limbs and hands of stroke patients. Background technique [0002] According to 2001 statistics, more than 25,000 people suffer from stroke in Hong Kong every year and are admitted to hospital for treatment. [0003] Functional electrical stimulation systems (Functional Electrical Stimulation [FES]) stimulate movement by artificially stimulating a patient's muscles or muscle groups using electrical current. As early as 1971, Liberson used electrical stimulation to assist the walking of patients with foot drop. Current FES systems are primarily designed for patients with spinal cord injury and stroke. [0004] Many researchers have designed implantable electrodes and systems for patients with spinal cord injury. These systems need to be surgically implanted into the ...
