The maximal double step length test can evaluate more adequately the decrease of physical function with age , than the maximal single step length test . The maximal double step length ( MDSL ) test is a modified version of the maximal step length ( MSL ) test used to evaluate the dynamic balance related to falls in the elderly . Although this test can evaluate their physical function using movements similar to daily activities as compared to MSL , it has not been clarified whether it can adequately evaluate the activities of daily living ( ADL ) abilities of the elderly , as they decrease with age . This study aimed to examine the relationship between both MSL and MDSL on age and ADL in elderly subjects . Fifty-seven elderly females who live independently ( age 74.8±5.6 years ) were recruited . MSL and MDSL were conducted twice after completing an ADL questionnaire . Intra-class correlation coefficients ( ICCs ) of both tests were high ( for MSL : ICC=0.95 , for MDSL : ICC=0.81-0.82 ) . Age and ADL significantly correlated to MDSL ( age : r=-0.32-0.41 , ADL : r=0.28-0.48 ) , but not to MSL ( age : r=-0.19 , ADL : r=0.15 ) . MDSL has high reliability as it relates to age and ADL . It may be more useful to evaluate ADL required for independent living and prevent falls in the elderly better than MSL .
