A non-invasive method comprising positioning a first electrode on a lower end of a lower leg, a second electrode on the lower leg, and a third electrode on an upper end of the lower leg, whereby the first and third electrodes are disposed on opposite ends of the lower leg, and the second electrode and one of the first and third electrodes are disposed on a same end of the lower leg; effecting a sequence of muscular contractions of the lower leg by (i) applying a first electrical impulse between the electrodes on the same end of the lower leg to induce a first muscular contraction and (ii) applying at least a second electrical impulse between the first and third electrodes to induce a longitudinal muscular contraction; and repeating operations (i) and (ii), to repeatedly induce the contractions, to effect the increased flow of blood.

The invention discloses an intelligent rhythm interactive electromyographic signal muscle rehabilitation treatment system. The system comprises a surface electromyographic sensor, a signal emitter and a rhythm interaction device, wherein the surface electromyographic sensor is arranged for acquiring an electromyographic signal of a user; the signal emitter is arranged for receiving and emitting the electromyographic signal; the rhythm interaction device is arranged for generating and providing a specific rhythm to the user and receiving the electromyographic signal; when the electromyographic signal is matched with the specific rhythm, positive feedback is provided; otherwise, negative feedback is provided. The muscle rehabilitation treatment system is adopted, so that a user continuously enhances and exercises target muscle or muscle group, skilfully operates the target muscle through motor nerves and inhibits wrong muscular contraction to achieve an effect of counterbalancing the muscle group through the rhythm interaction device; the muscle rehabilitation treatment system also has extremely high interactivity, intelligence and interestingness, improves the will of the user for adherence to treatment and makes the autonomous treatment possible for the user.

The invention provides a method for evaluating the steering control efficiency of a vehicle driver. The method comprises the following steps of: installing a steering sensor on a steering column of a vehicle to measure a steering force from the driver, attaching a muscle electrode to the shoulder muscle of the driver to collect a myoelectric signal of the shoulder muscle group of the driver, and establishing estimation equations of effective steering force and total steering force during steering control of the driver by regression analysis in combination with a model of relationship between the driver myoelectric signal and the muscular contraction force. The method achieves the purpose of evaluating the steering control efficiency of the driver and provides a theoretical basis for evaluating the steering comfort of the driver and the performance of the steering system. The method is suitable for the steering control of various vehicles and can be widely applied to the evaluation of driving comfort and steering system performance.
