Muscle groups were tested separately for each leg and values were averaged for the two legs. A ratio of maximal muscular strength to body weight was calculated by dividing the muscular strength (N) by body weight (kg). <\/jats:p><jats:p> Results: Muscular strength thresholds to perform ADL independently were 2.3 N\/kg for hip flexors, 1.7 N\/kg for hip extensors, 0.7 N\/kg for knee flexors, 2.8 N\/kg for knee extensors and 2.8 N\/kg for ankle dorsiflexors. <\/jats:p><jats:p> Conclusion: The thresholds of lower extremity muscle strength below which assistance is required to perform ADL in community-dwelling older adults were identified. Furthermore, results indicate that the muscular strength of hip extensors is more important in performing ADL than other muscles of the lower extremities.
