Self-report (SF-36 Physical Function Subscale (SF-36pfs), Functional Performance Inventory-Short Form (FPI-SF)) as well as performance-based (Short Physical Performance Battery (SPPB), skeletal muscle strength) measures were taken at hospital discharge, 2, 4, and 6 months post-enrollment.

At 2 months, weak to moderate correlations were found between self-report and performance measures in both groups. In the SoC group, the SF-36 was significantly correlated with the SPPB (r = 0.47) and muscular strength (r = 0.34); the FPI was significantly correlated with the SPPB (r = 0.64) and muscular strength (r = 0.52. In the ExP group, the SF-36 was significantly correlated with the SPPB (r = 0.61) and muscular strength (r = 0.42); the FPI was significantly correlated with the SPPB (r = 0.54) and with muscular strength (r = 0.28).
