Objective: To evaluate whether there is a difference in lower limb muscle strength in elderly fallers and non-fallers after chronic stroke. Methods: Cross-sectional observational study. Individuals after chronic stroke had their knee extensor and plantar flexor muscle strength assessed by the modified sphygmomanometer test, and the residual deficit was obtained using the formula: 100 - [(strength on paretic side/ strength on non-paretic side)] X 100. The incidence of falls was obtained through a direct question to the individuals, in which they were asked whether they had had falls in the last 6 months. The Independent Student t test was used to compare the lower limb muscle strength of the fallers and non-fallers. Results: 53 individuals, 43% male and a mean age of 71.1 (7.5) years were included. The mean of falls in the last 6 months was 4.1. Twenty-two (41%) individuals were fallers. Non-fallers individuals presented higher knee extensors muscle strength of the paretic side (MD=0.52mmHg; 95%CI 9.50 to 78.47; p=0.01). Non-fallers individuals presented lower residual deficit of knee extensors (MD=0.17mmHg; 95%CI -30.21 to -2.28; p=0.02). Conclusions: Elderly individuals after chronic stroke that are fallers have less strength of knee extensors at the paretic side and present more RD of knee extensors.
