Example Embodiment

[0022] The invention discloses a method for controlling the standing mode of an exoskeleton mechanical leg rehabilitation system. The exoskeleton mechanical leg rehabilitation system includes two mechanical legs. Each mechanical leg includes a hip joint motor and a knee joint motor. Hip and knee joints. The control principle of the two legs is the same. Each joint motor adjusts the output torque according to the muscle state. The specific implementation includes the following steps:

[0023] Step 1: Attach the array surface electrodes to the muscles of the left and right legs, namely the quadriceps femoris of the thigh and the gastrocnemius of the calf. Clean the surface of the skin with medical sandpaper and alcohol before sticking, and place the electrodes on the muscles of the muscles. According to the size of the patient’s muscles, the number of array electrodes can be appropriately increased, and the electrodes are distributed in a circle perpendicular to the leg. The dist...

Abstract

The invention provides an exoskeleton mechanical-leg rehabilitation system standing mode control method. After a standing mode is started, array-type electromyographic signals are firstly decomposed, then characteristic parameters (motion unit number, issuing frequency and issuing waveform energy) of muscular movement units are extracted and are quantified, and finally a staged driving joint motor outputs a torque according to the quantified characteristic parameters to assist a patient for leg muscle rehabilitation training. Due to the fact that the method is based on the characteristic parameters of the muscular movement units, a muscle state can be also reflected, and the method is very conductive to patient rehabilitation and has the advantage of being simple to achieve.

Description

technical field [0001] The invention relates to the field of auxiliary medical rehabilitation training equipment, and in particular designs a control method for the standing mode of a lower limb rehabilitation system using the feedback of the patient's electromyographic signal. Background technique [0002] At present, due to the increasing number of patients caused by muscle atrophy and other problems, they are not only inconvenient in movement, but also under great psychological pressure. It has become their urgent desire to improve their limb functions with the help of rehabilitation equipment. The exoskeleton mechanical leg is a mechanical device that is worn on the lower limbs and driven by motors at the joints to assist the movement of the lower limbs and achieve the function of rehabilitation training. In order to solve the physical problems of patients such as muscle atrophy, help them stand and walk again, and improve their quality of life, it is of great practical ...
