1results about How to "Prevent regression" patented technology

This invention relates to the field of healthcare informatics technology, specifically to a virtual reality rehabilitation training method and system based on motion contrast feedback. The method includes: generating standardized relative motion data; calculating the motion completion score, motion fluency score, and coordination score for each key point based on the standardized relative motion data, and weighting and fusing them to obtain the current anomaly index for each key point; calculating the structural centrality weight and mechanical leverage weight for each key point, and weighting and fusing them to obtain the next-stage importance weight for each key point; using the current anomaly index and the next-stage importance weight, obtaining the next-stage limitation index for each key point; calculating the predicted completion rate based on the next-stage limitation index, and then calculating the total stage fit score; and determining whether the target subject is allowed to enter the next stage of training based on the total stage fit score. This invention can improve the adaptability and risk control capabilities of rehabilitation training.
