Abstract：Objective To quantitatively assess the lower extremity muscle strength of the elderly. Methods From December, 2016 to March, 2017, 50 old subjects were enrolled. The evaluation indexes of lower extremity muscle strength of the elderly were determined as hip abductors, hip adductors, hip extensors, hip flexors, knee extensors, knee flexors, ankle dorsiflexors and ankle plantarflexors with the hand-held dynamometry. The data of 50 subjects were collected and the grey relational analysis model was used to make the decision and evaluation. The grading criteria for lower limb muscle strength of the elderly were given by Manual Muscle Test. Results Totally, 13 elderly subjects were well-matched, and the other 37 subjects were mildly disordered. Conclusion Based on the need for quantitative assessment of muscle strength of the lower limbs in the elderly, an objective evaluation model of the lower extremity muscle strength of the elderly was es-tablished, which facilitated to grade the elderly lower extremity muscle strength and then to carry out different rehabilitation guidance.
