To clarify easy-to-use methods of lower-extremity functional assessmentfor day- care providers, 34 elderly females using day services were assessed using the 30- second Chair Stand Test (CS-30) and 10-second Chair Stand Test for the FrailElderly (Frail CS-10), in addition to measuring their quadriceps femoris muscle strength, and the correlations between these test scores/the quadriceps femoris muscle strength and each physical function parameter were analyzed. The quadriceps femoris muscle strength showed a significant correlation only with the hand grip strength, whereas both CS-30 and Frail CS-10 scores were significantly correlated with the hand grip strength, time needed to walk 5 m at the maximum gait velocity, Timed Up Go Test score, and Trail making test Part A score. The Frail CS-10 score was also significantly correlated with the time needed to walk 5 m at a normal gait velocity. The results support the usefulness of Frail CS-10,which allows service providers to conveniently and promptly conduct assessment without special devices, to assess the walking ability and dynamic balance of elderly day- care users.
