Table 4.

Within-group differences between hospital discharge (T0) and 3 months post operation (T2) and between-group differences at T2 in measures of functional status. Within-group differences represent the differences in functional status between T0 and T2. Beta values represent the differences in functional status between the historical control group and the intervention group at T2.

^aT0: hospital discharge.

^bT2: 3 months post operation.

^cLHGS: left-hand grip strength.

^dP<.05 is considered significant.

^eRHGS: right-hand grip strength.

^fMIP: maximal inspiratory pressure.

^gThese measurements were not performed at T0 and therefore were excluded from this analysis.

^hMissing data.

ⁱ30CST: 30-second chair stand test.

^j2MWT: 2-min walk test.

^kADL: activities of daily life.

^lHRQL: health-related quality of life.
