Embodiment Construction

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

[0039] figure 1 It is a structural schematic diagram 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. There are two basic configurations of the functional electrical stimulation system. In a first configuration, initial setup and configuration parameters of the FES system may be performed. In the second configuration, the portable host 110 works in a stand-alone mode and is not connected with the PDA 190 and a computer.

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

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