Abstract

The embodiment of the invention discloses a wearable functional electrical stimulation system taking an electromyographic signal as a control switch, the movement of a shank is predicted by detecting the electromyographic signal on the skin surface of the thigh rectus femoris with the same time sequence as the gait of the shank, and the electromyographic signal greater than a certain threshold value is used as a switch for starting an electrical stimulation module, so that the movement of the shank is predicted. Therefore, the time sequence of pulse wave generation is controlled by the biological signal which is more fit with the consciousness of the patient, the problem of inaccuracy of the starting time of a traditional electrical stimulator is solved, muscle fatigue caused by redundant electrical stimulation is effectively avoided, and the stimulation time of the system is more efficiently fit with the walking gait of the foot drop patient.

Description

technical field

[0001] The embodiment of the present invention relates to the field of biomedical technology, in particular to a wearable functional electrical stimulation system using surface electromyographic signals as control switches. Background technique

[0002] Stroke has become one of the most common chronic diseases in the world. Foot drop is one of the sequelae that may occur in stroke patients. It is manifested as difficulty in lifting the toe part due to weak leg muscle contraction. The emerging functional electrical stimulation technology uses biphasic pulse current to stimulate the limbs that have lost function, thereby causing muscle contraction in the stimulated area, and has become an effective method for the treatment of foot drop diseases.

[0003] Most of the existing functional electrical stimulators for the treatment of foot drop use plantar pressure sensors or leg inclination sensors as the on-off switches, which have problems such as inaccurate on-t...
