A simple method for estimating lower limb muscle strength in the elderly and standing assistance according to the individual's physical weakness

This paper proposes a new estimation method for the lower limb muscle strength of the elderly that can be easily performed in nursing care facilities. Furthermore, based on the estimated lower limb muscle strength information, this paper proposes a human model that simulates the physical conditions of the elderly and, using this model, proposes a new design method for standing assistance strategy adapted to the physical conditions of the elderly. The main advantage of the proposed method is that it can estimate and model leg muscle strength, which depends on the individual elderly person, in a simple way that can be carried out by staff in nursing care facilities who are not engineering specialists, without the use of specialized measuring equipment such as electromyography.
