Effect of controlled start position on the reach distance distribution range in the functional reach test among community-dwelling older adults.

[Purpose] This study investigated the effect of controlled start position (CSP) on the reach distance distribution range (RDDR) in the functional reach test (FRT) in community-dwelling older adults. [Participants and Methods] The participants were 34 community-dwelling older adults. We compared the RDDR in CSP and non-CSP and analyzed the relationship between the mean reach distance (MRD) and the length of movement of the center of pressure (LMCOP). [Results] The RDDR in CSP condition was significantly lower than non-CSP condition. A significant positive correlation was observed only for CSP condition. In the non-CSP condition, MRD was not reflected in the LMCOP. [Conclusion] The FRT in the CSP effectively reflects the standing balance ability of community-dwelling older adults.
