Human body balance assessment system and assessment method

Abstract

The invention provides a human body balance assessment system and assessment method. The human body balance assessment system includes a man-machine interaction module, an action comparison module, a plantar pressure detection module, and a balance index quantification module. The human body balance assessment method includes: setting an application scene in the man-machine interaction module, allowing interactive actions between the human body and the application scene, using a somatosensory sensor to record three-dimensional coordinates of corresponding nodes of a human body skeleton model in real time, and using a plantar pressure sensor to measure the plantar pressure in real time; calculating the angles of human body joints, and determining if the action is standard or not; performing pretreatment on the plantar pressure value if so, and calculating the plantar pressure center; and assessing the balance ability of a human body according to the offset degree of the plantar pressure center. The somatosensory sensor and the plantar pressure sensor are combined; standard actions with different difficulties are designed for people groups with different balance disorders; the objectivity and the reliability of balance assessment can be improved; and the human body balance assessment system and assessment method has wide application value.

Description

technical field [0001] The invention relates to a human body balance index intelligent detection device, in particular to a human body balance evaluation system and evaluation method based on body sensory sensors and plantar pressure. Background technique [0002] Human balance ability refers to the ability of the human body to maintain its own stability, including the ability to maintain a certain posture, or the ability to regulate the body to maintain balance when subjected to external forces. Balance ability is one of the important physiological functions of the human body, and it is also an important indicator of the human body's motor function. Impaired balance ability is mainly manifested as unsteady standing or walking, and easy to fall. For the elderly and people with impaired lower limb function, their falls will cause a great burden to the family and society. Therefore, monitoring and evaluating the balance ability of the human body plays an important role in pr...
