Description
Technical Field
The invention relates to the field of medical rehabilitation training equipment, in particular to a use method of a training device for postoperative recovery of a surgical elbow joint.
Background
Rehabilitation medicine is a medical application subject for researching the rehabilitation of disabled people and patients, and aims to recover the disabled people to the maximum extent as soon as possible by various means such as physical therapy, motor therapy, life training, skill training, speech training and psychological consultation, so that the functions of the residual parts of the bodies are exerted to the maximum extent, the maximum possible self-care of life, the labor and the work capacity are achieved, and a foundation is laid for the disabled people to return to the society.
After the elbow joint operation, the most common complication includes that the elbow joint is stiff and the elbow joint range of motion is limited, for improving treatment and quality of life, the postoperative needs to carry out early rehabilitation training, accelerates the recovery of elbow joint function, and the prevention complication takes place, and during elbow joint rehabilitation training, can not rely on the auxiliary function of rehabilitation training device completely, patient also need exert oneself the training when rehabilitation training, lets the rehabilitation device only provide supplementary.
The postoperative rehabilitation training action of the elbow joint is generally as follows:
training person holds two fixed stay cords to the adjustment posture is to being the tilt state, and face up, and training person changes the inclination on health and ground through elbow activity pulling health, makes the angle change between forearm and the big arm, carries out the activity and resumes the training, and the action main points are:
1. the large arm is tightly attached to the body to do revolving swing along the shoulder, so that the revolving swing direction of the large arm is kept consistent, and the joint burden is reduced;
2. the small arm is tightly attached to the body to do revolving swing along the large arm, so that the revolving swing direction of the small arm is kept consistent, and the joint burden is reduced;
3. the waist and the back are kept straight, the moving part is the elbow, and the training effect is improved.
Because the activity of postoperative elbow is limited, can bring the misery of certain degree for the training person when the elbow resumes the training, the training person must necessarily can tend to reduce the misery, therefore moves the easy deformation, often shows:
1. when the small arm swings to the limited position along the large arm, a trainer can naturally enable the small arm and the large arm to leave the body to achieve a larger training swing angle, but the elbow activity is not the main of the activity part of the actual action after the small arm and the large arm leave the body, and the recovery training of the elbow is minimally facilitated;
2. the waist and the back are not straight, and a seemingly larger training swing angle is achieved by means of the front and back movement of the scapula, and the defects are the same as the above;
3. under the action of gravity, the crotch sags in the moving process, so that the angle between the lower half body and the ground is not consistent with the angle between the upper half body and the ground, the upper half body is almost vertical to the ground, the waist burden is increased, the action is easily changed into the pull-up of the whole body movement, and the action deformation is more easily caused.
Therefore, the training process in the prior art needs continuous guidance and action correction by people to achieve the best training effect, but a trainer is easy to slip due to the fact that the body of the trainer inclines to the ground, the action is difficult to keep, and the pulling force applied by the trainer during training is determined by the body weight, the lever length formed by the body and the stress angle, so that the trainer is not beneficial to carrying out proper balance weights aiming at different recovery periods, in addition, the stress angle is continuously changed during training, the lever length formed by the body is also continuously changed when the action is deformed, the training load is also continuously changed, the trainer easily exceeds the self stress limit due to the changed force, so that elbows are injured, the independent and correct training of the trainer is facilitated, the stability of the training balance weights is kept, and the use method of the training device for postoperative recovery of the surgical elbow joint is provided.
