Background/Objectives: Accurate assessment of physical activity is essential in hospital settings, but difficult for geriatric rehabilitation patients who have slow walking speed and rely on walking aids. This study conducted an external validation of the MOX activity monitor accuracy in distinguishing between sedentary (lying, sitting), standing, and dynamic activities among hospitalized geriatric rehabilitation patients. Additionally, the study assessed clinical tolerance and ease of use of the monitor. Methods: Inclusion criteria were being hospitalized on the geriatric rehabilitation ward, aged 70 years or older, and using a walking aid. The monitor was placed on the upper leg, and remained in place for 1 week. In a test-session, four activities of 4 min each (lying, sitting, standing, and walking) were filmed. Video analyses created a direct observation timeline. Daily skin irritation assessments were conducted and participants noted their discomfort level at the week’s end. Results: The study included 20 participants who relied on walking aids, with 10 requiring additional physical support while walking. The MOX activity monitor exhibited excellent accuracy in classifying the four activities, with a zero mean percentage error for sedentary activity, 2.2% for standing, and 2.7% for walking. Participants reported minimal hindrance, and the monitor proved user-friendly. Conclusion: The MOX activity monitor demonstrated remarkable accuracy in distinguishing between these four activities in a test-session and displayed strong clinical applicability. Significance: The monitor shows substantial promise as a valuable tool for assessing physical activity in hospitalized geriatric rehabilitation patients using walking aids.

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.

BACKGROUND AND PURPOSE Regaining functional independence and independent living is challenging in hospitalized geriatric patients. Different from community dwelling and institutionalized older people, geriatric patients on rehabilitation wards generally receive more frequent and structured physiotherapy with the primary aim to discharge them to their home or place of residence. There is a paucity of evidence concerning the structure and components of physiotherapy programs to improve functional performance in this particular group. In this paper, we describe how we developed the Geriatric Activation Program Pellenberg (GAPP) based on patients' needs and available literature. METHODS We searched the literature on physiotherapy interventions focusing on the core components for improvement of functional performance: strength, balance, function, (gait)speed, coordination, and endurance training. Based on physiotherapist staffing and physiotherapy time allocated to each patient, we organized the practical, daily delivery of the program. RESULTS GAPP is a 5-day program, repeated weekly, delivered by physiotherapists and physiotherapy students. Each day, one or a combination of two to three different core components of functional performance is trained intensively in 45-min sessions. A set of standard exercises is constantly adjusted to each patients' capacity. On day 5, there is a mix of these core elements in a group session (e.g., chair-dance, table tennis, karate) and the Berg Balance Scale is completed to evaluate progress. CONCLUSION GAPP is a multicomponent physiotherapy program for hospitalized patients on a geriatric rehabilitation ward, aimed at improving functional performance.
