Foot drop adaptive stimulator (contact email: meddut@dlut.edu.cn)
I. Product and Technology Introduction:
It belongs to the human rehabilitation auxiliary instrument, which is suitable for the foot drop caused by the loss of control of the common peroneal nerve after stroke. It involved the detection of the patient's calf posture when walking, and timely release of electrical stimulation pulse to force the patient to automatically lift the foot to complete the walking movement. Before the patient stepped out of the lower leg, according to the movement speed, it automatically continued stimulation for a certain period to maintain the lifting of the foot.
In view of the shortcomings of the present situation, the invention adopts a simple placement process, that is, it is fixed at the tibial tuberosity under the knee joint, and no matter the left foot or the right foot, it can be determined by the left and right stimulation electrode selection switch. It can be used normally after adjusting the stimulation intensity according to individual characteristics. The utility model can automatically select the appropriate time to issue the stimulation current according to the walking stride size and speed of the patient, and automatically continue the stimulation in a certain period according to the movement speed before the patient steps out of the lower leg to maintain the lifting of the foot, so that the patient can resume normal walking function.
Ii. Scope of application:
After mild stroke, it will cause loss of control of the common peroneal nerve, and then cause foot drop. These patients are able to take care of themselves, but cannot raise the tip of their feet during walking. Improving the self-care ability and quality of life of these patients has great social significance and economic benefits.
