The BBS estimation was
analyzed for combinations of one, two, and three tasks, for determination
of which tasks lead to the best BBS score estimation
result. There would be 1001 distinct combinations of four tasks
out of nine, so the set size was limited to three tasks in this case.
With the exception of one subject in the neurological-patient
group for the stand to sit task, data existed for all nine tasks
selected for all 49 test subjects
