Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of rehabilitation training, and particularly relates to an upper and lower interactive proprioceptive training device. BACKGROUND

[0002] Limb dysfunction is that the original normal function of the limb is weakened or lost. The limbs of normal people have movement and sensory functions. The function of the upper limbs mainly includes fine actions such as grasping under the instruction of the brain and the coordination of the trunk and the upper limbs, and correct judgments on temperature, pain, and limb position. The function of the upper limbs is more delicate and flexible than that of the lower limbs, and the functions of the left and right limbs of normal people are basically symmetrical. When the brain, spinal cord, peripheral nerves are damaged or the limbs are injured, limb dysfunction occurs, such as abnormal sensation and movement caused by cerebral infarction, cerebral hemorrhage, trauma, etc., which is manifested as limb weakness and inability to correctly distinguish pain, temperature, position, etc.

[0003] Proprioception is the sensation of joints, limbs, movement and force, which refers to the sensation of deep structures such as muscles, tendons, joints and ligaments. It is the sensation of feeling that the muscles are in a state of contraction or relaxation, the tendons and ligaments are pulled, and the joints are in a state of flexion or extension. The deep sensory conduction of the trunk and limbs is through the cell body of neurons, which is located in the spinal ganglion and distributed in the muscles, tendons and joints. Proprioception can be divided into three levels. The first level is the position sensation, movement sensation and weight bearing sensation of muscles, tendons, ligaments and joints. The second level is the balance sensation of the vestibule and the movement coordination sensation of the cerebellum. The third level is the comprehensive movement sensation of the cerebral cortex. The proprioceptive loss of patients with bone injury is mainly the first level loss, the proprioceptive loss of patients with movement injury is mainly the first and second level loss, and the proprioceptive loss of patients with nerve injury is mainly the third level loss.

[0004] The postoperative care and functional rehabilitation exercise of upper limb dysfunction patients are very important. For example, passive activity and resistance training of the upper limbs during the rehabilitation period are needed to restore the proprioception of the patients, thereby avoiding muscle loss, osteoporosis and joint contracture caused by long-term muscle relaxation, and the decline of hand function and flexibility caused by long-term abandonment of the hand joints. At present, the rehabilitation exercise methods mainly include the auxiliary exercise of nursing personnel (such as massage and passive stretching) and the exercise of equipment. At present, the equipment mainly passively stretches the upper limbs of the patients or provides certain resistance training, and some equipment has the functions of massage and pneumatic therapy. However, the current equipment exercise method lacks the concept of upper and lower limb interaction and lacks the controllable exercise method of the patients. Through the upper and lower limb interaction, the proprioception of the patients can be better exercised, and the self-control can avoid injury during the rehabilitation exercise, which is safer and saves the time and energy of the nursing personnel.
