Sixteen-week ceiling effects for the total sample and by subgroups of baseline functional limitation. BBS=Berg Balance Scale, POMA-T=Performance-Oriented Mobility Assessment total scale, POMA-B=Performance-Oriented Mobility Assessment balance subscale, DGI=Dynamic Gait Index. Severely limited function=baseline Short Physical Performance Battery (SPPB) score of 5 to 6, moderately limited function=baseline SPPB score of 7 to 9, mildly limited function=baseline SPPB score of 10. Significant differences: ∫=between BBS and POMA-T, √=between BBS and POMA-B, ⊥=between BBS and DGI, ◇=between POMA-T and POMA-B.
