In-hospital rehabilitation with the Geriatric Activation Program Pellenberg improves functional performance in a heterogeneous geriatric population

ABSTRACT

Background

Regaining independent living can be challenging in patients undergoing inpatient geriatric rehabilitation. Given the paucity of evidence-based physiotherapy programs for this particular heterogeneous group, the Geriatric Activation Program Pellenberg (GAPP) was developed.

Purpose

Investigate the evolution of functional performance, and predict detectable changes throughout 4 weeks of GAPP. Methods: Participants in this observational study (2017–2019) followed GAPP as part of their rehabilitation program. Functional balance (Berg balance scale (BBS)) and independence (Katz scale) were the primary outcomes, with gait speed, elbow and knee extension strength, cognitive processing speed, and mood as secondary outcomes. All outcomes were assessed at baseline, 2 weeks and 4 weeks later. Prediction analysis was conducted using logistic regression modeling. Previously reported minimal detectable change with 95% confidence interval (MDC95) was used as detectable change.

Results

We recruited 111 participants, with 83 completing 4 weeks of GAPP and all assessments. Over 4 weeks, all outcome measures showed a significant improvement (p ≤ .007). Detectable change was found for BBS (mean improvement of 12.8 points (95% CI: 10.9–14.8), MDC95 = 6.6) and gait speed (mean improvement of 0.24 m/s (95% CI: 0.19–0.29), MDC95 = 0.1 m/s). We found that baseline scores lower than 26 on the BBS (75% sensitivity, 65% specificity) and gait speed lower than 0.34 m/s (53% sensitivity, 81% specificity) were associated with participants achieving detectable change at 4 weeks on BBS and gait speed, respectively.

Conclusion

Functional performance of a heterogeneous group of geriatric inpatients improved notably after 4 weeks of GAPP. Baseline scores on BBS and gait speed can partially predict detectable changes in functional performance.
