Conclusions
This study suggests that when evaluating the benefits of SCET for CH older adults and those with CI using responsiveness and MCID of dual tasks involving cognition and hand function, SST performance when tasked with BBT and FD performance when tasked with BBT should be used as indices, respectively. A change in SST performance when tasked with BBT between 2.09 and 2.36 corrected numbers is considered meaningful for CH older adults. In comparison, a change in FD performance when tasked with BBT between 1.47 and 2.18 corrected numbers is considered a meaningful change for CI older adults.
