Transdural Electrode Device for Stimulation of the Spinal Cord

technical field

The invention relates to the technical field of rehabilitation training equipment, in particular to a transdural electrode device for stimulating the spinal cord.

Background technique

Spinal cord injury is the most serious complication of spinal cord injury, which often leads to serious dysfunction of the limbs below the injured segment. Spinal cord injury will not only bring serious physical and psychological harm to the patient himself, but also cause a huge economic burden to the whole society. Rehabilitation training refers to physical activities that are beneficial to recovery or improvement of function after injury. Except for serious injuries that require rest and treatment, general injuries do not need to stop physical exercises completely. Appropriate and scientific physical exercises are conducive to the rapid healing of injuries and the promotion of functions. Rehabilitation has a positive effect, and the rehabilitation training plan follows the principles of comprehensive training, gradual progress, and suitable for large amounts of exercise. In the process of injury healing, the amplitude, frequency, duration, and load of rehabilitation actions should be gradually increased, otherwise, the injury will be aggravated or the healing of the injury will be affected, and even the injury will not heal for a long time and become an old injury. Rehabilitation training Attention should be paid to the combination of local specialized exercises and comprehensive physical activities. In the early stage of the injury, due to local swelling and congestion, pain and dysfunction, etc., at this time, full-scale physical activities are the mainstay. On the premise of not aggravating local swelling and pain, appropriate local activities are performed. As time goes by, the injury gradually improves Or it tends to heal, and the amount and time of local activities can be gradually increased.
