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

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.
