Passive movement running wheel for weight-losing walking of rat with spinal cord injury

Abstract

A weight-losing walking passive movement running wheel for a rat with spinal cord injury belongs to the field of rehabilitation training of the rat with spinal cord injury and comprises a running wheel assembly, a hind limb supporting assembly and a suspension assembly, the running wheel assembly comprises a first driving mechanism, a supporting frame, a support and a rotating running wheel, the first driving mechanism is mounted on the upper portion of the support and drives the running wheel to rotate, and the supporting frame is mounted on the supporting frame. The suspension assembly comprises a brace and a suspension frame for suspending the brace, a first opening and a second opening which are opened are formed in the two ends of the brace in the length direction, and two forelimb holes are formed in the positions, close to the first opening, of the outer side of the brace; according to the passive movement running wheel for weight-losing walking of the rat with spinal cord injury, in-situ weight-losing gait rehabilitation training can be carried out on the lower limbs on a running machine, the dragging gait of the rat with spinal cord injury can be changed, nerve regulation and control of walking can be influenced, the effect of muscle training can be achieved for the rat with lower limb strength, the step speed is increased, and the balance function is improved.

Description

technical field [0001] The invention relates to a passive exercise running wheel used for weight loss and walking in spinal cord injury rats, and belongs to the field of rehabilitation exercise for spinal cord injury rats. Background technique [0002] Spinal cord injury can cause important disability, and later secondary injury and complications will increase the difficulty of rehabilitation. In recent years, rehabilitation equipment such as power bicycles, hand function trainers, etc. have been widely used. A device that combines passive activity with the running wheel of the rat's running exercise. It is used for spinal cord injury rats to make passive movement of the lower limbs during exercise. Clinical and experimental studies have shown that this kind of brace can effectively promote the lower limbs of patients with spinal cord injury. The recovery of residual motor function and the promotion of lower extremity muscle tone reduction, but its biological effects and spe...

Problems solved by technology

[0002] Spinal cord injury can cause important disabilities. Later secondary injuries and complications will increase the difficulty of rehabilitation. In recent years, rehabilitation equipment such as power bicycles and hand function trainers have been widely used. This technology creates a simulated manual A device that combines passive movement with a running wheel for rats to run is used for rats with spinal cord injuries to enable them to perform passive movement of the lower limbs during exercise. Clinical and experimental studies have shown that this kind of brace can effectively promote the lower limbs of patients with spinal cord injuries. Restoration of residual motor function and reduction of lower extremity muscle tone, but its biological effects and specific mechanisms are still unclear

Using experimental animals with spinal cord injury to study its biological effects and mechanisms has become an important means and content of spinal cord injury rehabilitation research. Although the weight loss walking training running wheel can perform passive movement and weight loss walking on the spine of rats with different degrees of injury, it is still in use. The following problems are prone to occur during the process: the rat's forelimbs and head are dragging and biting on the support; rats have obvious differences in weight and posture, and the specific value of weight loss is inaccurate
