Description

Dynamic posture balance based realistic rehabilitation exercise system

The present invention relates to a rehabilitation exercise system, and more particularly to a dynamic posture balance based rehabilitation exercise system.

Balance ability is the ability to keep the body in equilibrium, that is, to maintain the center of gravity on its base in the right posture, which has a significant effect on all movements.

This balancing ability can be largely divided into static balancing ability and dynamic balancing ability. Static balance ability refers to the ability to maintain balance when maintaining posture. The ability to maintain body position by placing the center of gravity within the supporting base surface and dynamic balance ability maintains balance when the body moves. The ability to maintain the desired posture by keeping the center of gravity within the support base while moving.

Factors affecting balance can be divided into musculoskeletal and neurological factors. Musculoskeletal factors are all processes in which the musculoskeletal system affects postural alignment and flexibility needed for balance. Sensory processing here refers to the control of vision, vestibular and proprioceptive systems. In addition, physiological factors such as muscle tension, hearing and attention, and fear, and environmental factors such as the condition of the sole of the shoe and clothing also affect balance.

The pitch motion frame may include a vibration device for applying vibration stimulation to a user.

The scaffolding unit may include a pressure sensor for detecting foot pressure of a user and transmitting the pressure to the main body.

The dynamic posture balance based sensory rehabilitation exercise system may further include a biosignal measuring sensor attached to a body of a user to measure a biosignal of the user and transmit the biosignal to the main body.
