Description

Upper limb auxiliary proprioception training device for patient with lower limb dysfunction

Technical Field

The utility model belongs to the technical field of rehabilitation training, and particularly relates to an upper limb auxiliary proprioception training device for patients with lower limb dysfunction.

Background

The limb dysfunction is the weakening or losing of the original normal functions of the limb, the limb of a normal person has the functions of movement and sensation, the functions of the lower limb are mainly coordinated with the trunk and the upper limb under the instruction of the brain so as to complete the actions of walking, jumping, running and crossing, and the temperature, pain, limb position and the like can be accurately judged. When brain diseases, spinal cord diseases, peripheral nerve injuries and limb injuries occur, limb dysfunction, such as limb sensory and motor dysfunction caused by wounds, difficulty in walking or inability to walk, weakening of limb strength, incorrect discrimination of pain, temperature, position and the like, occurs;

proprioception is the sensation of the joint, limb, movement and stress, which means the sensation of feeling deep structures such as muscles, tendons, joints and ligaments, namely, the sensation that the muscles are in a contracted or relaxed state, whether the tendons and ligaments are pulled, whether the joints are in a bent or straightened state, and the like, and deep sensory conduction of the trunk and limbs is that a cell body passing through neurons is located in the spinal ganglion and distributed in the muscles, tendons and joints; proprioception can be classified into three classes, one class refers to the positional sensation, motor sensation, and load sensation of muscles, tendons, ligaments, and joints; the second level is the balance sensation of the vestibule and the motor coordination sensation of the cerebellum; third level is the brain cortex comprehensive motor sensation; proprioception loss of a patient with bone injury is mainly primary loss, and proprioception loss of a patient with motor injury is mainly primary loss and secondary loss; proprioception loss in nerve-injured patients is mainly tertiary.
