Objective: To determine the thresholds of lower extremity muscle strength below which performing activities daily living (ADL) is impaired in older adults. Design: Cross-sectional. Setting: Community. Subjects: Forty-nine adults (81—89 years) were divided into an independent group (n = 25) who needed no assistance and a dependent 24) to perform ADL. Interventions: Not applicable. Main measures: Functional independence measures level disability muscular hip flexors, extensors, knee extensors ankle dorsiflexors assessed by hand-held dynamometer (HHD). Muscle groups tested separately for each leg values averaged two legs. A ratio maximal body weight was calculated dividing (N) (kg). Results: Muscular ADL independently 2.3 N/kg 1.7 0.7 2.8 dorsiflexors. Conclusion: The required community-dwelling identified. Furthermore, results indicate that more important than other muscles extremities.
