Abstract: Accidental falls are common among the elderly and could cause various injuries which in turn seriously impact their health and quality of life. Therefore, falls in the elderly have become one of public health concerns. This paper attempted to review the assessment methods of functional imbalance among old people from postural, gait and overall balance, sensor neuromuscular ability and other aspects, in combination with the analysis of current state of arts and practical application prospects both home and abroad. This review provides theoretical support for clinical and scientific research on the evaluation of imbalance performance among the elderly.
