Phase II cardiac rehabilitation improved the Short Physical Performance Battery score by a mean of 0.8 points overall (P<0.0001), with a 1.6-point increase in patients with low baseline scores.

Does phase II cardiac rehabilitation improve physical function measured by SPPB in patients aged 65 years or older?
Phase II cardiac rehabilitation significantly improves directly measured physical function, particularly in older patients presenting with low baseline physical performance.
p-value: p=<.0001
PURPOSE: The Short Physical Performance Battery (SPPB) is a strong predictor for risk of physical disability in older adults. Roughly half of individuals participating in phase II cardiac rehabilitation (CR) are 65 years or older, many presenting with low aerobic capacities and may be at increased risk for physical disability. METHODS: The cohort consisted of 196 consecutive patients (136 men), aged 65 years or older, entering CR who were prospectively evaluated by the SPPB. Data were also obtained for age, self-reported physical function (Medical Outcomes Study Short Form-36 questionnaire), and peak aerobic capacity. Measures were repeated upon completion of CR for those individuals who completed the program. RESULTS: The average age of patients was 74 ± 0.5 years. At baseline, total SPPB score was 9.7 ± 0.2 (out of 12). Followup data were obtained on 133 (68%) patients, with a mean improvement of 0.8 ± 0.1 (P < .0001), which was not clinically significant (≥1 point). Focusing on patients with a low baseline SPPB score, 72 subjects scored ≤9 (7.1 ± 0.2), with 45 completing exit measures. Improvements were found in gait speed (0.5 ± 0.1, P < .0001), chair-stand (1.0 ± 0.1, P < .0001), and total SPPB (1.6 ± 0.3, P < .0001) in this more disabled group. Measures of (Equation is included in full-text article.)O2peak were significantly reduced in the low SPPB group (13.5 ± 0.4 vs 17.5 ± 0.4 mL/kg/min, P < .0001). Measured (Equation is included in full-text article.)O2peak (R = 26%, P < .0001) and self-reported physical function score (R = 5%, P = .02) were the only multivariate predictors of baseline SPPB. CONCLUSION: For patients who enter CR with low SPPB scores (37%), significant improvements in physical function were noted, largely explained by improved walking speed and leg strength (chair-stand).
Rengo et al. (Fri,) conducted a cohort in Phase II cardiac rehabilitation (n=196). Phase II cardiac rehabilitation was evaluated on Change in Short Physical Performance Battery (SPPB) score (p=<.0001). Phase II cardiac rehabilitation improved the Short Physical Performance Battery score by a mean of 0.8 points overall (P<0.0001), with a 1.6-point increase in patients with low baseline scores.
