A feedback-control wearable upper-limb electrical stimulation device comprises a plurality of electrical stimulation electrodes ( 10 ), a plurality of myoelectric signal sensing elements ( 20 ), an electrical stimulation output unit ( 30 ), a myoelectric signal retrieval unit ( 35 ), a myoelectric signal operation unit ( 40 ), and a control module ( 50 ). Each electrical stimulation electrode ( 10 ) is adhered to or fixed in contact with a human trunk and applies an electrical stimulation signal to the neuromuscular system of the human trunk. Each myoelectric signal sensing element ( 20 ) is adhered to or fixed in contact with the human trunk at a corresponding position of the neuromuscular system of the human trunk where each electrical stimulation electrode ( 10 ) is disposed in an adhered manner. The electrical stimulation output unit ( 30 ) is connected to each electrical stimulation electrode ( 10 ) and provides an electrical stimulation signal. The myoelectric signal retrieval unit ( 35 ) is connected to each myoelectric signal sensing element ( 20 ) and receives a myoelectric signal. The myoelectric signal operation unit ( 40 ) is connected to the myoelectric signal retrieval unit ( 35 ). The control module ( 50 ) is electrically connected to the electrical stimulation output unit ( 30 ) and the myoelectric signal operation unit ( 40 ). The device first determines, according to the intensity of a myoelectric signal of a human trunk, the intensity of an electrical stimulation signal required for the human trunk to perform a specified action and gives a patient suitable assistance. Therefore, a local disabled limb of a patient can be effectively activated and a patient can be effectively exercised in controlling a diseased limb. |
