Time Effects on Physical Performance in Older Adults in Nursing Home: A Narrative Review.

OBJECTIVES: To gather available evidence about overtime changes on physical performance in institutionalized elderly. DESIGN, SETTING AND PARTICIPANTS: An electronic search was performed on PubMed database on May 2018. We selected articles reporting the evolution of physical performance in older adults living in care institutions. We looked for data from observational longitudinal studies; data from clinical trials were extracted only for subjects who did not receive exercise intervention. All types of performance-based tests, for upper- and/or lower-body, were scrutinized.
RESULTS: Seventeen studies were reviewed; mean age varied from 78.3 to 88 years old. Fourteen studies were randomized controlled trials (RCTs), other three studies were non-randomized trials and a longitudinal observational study. Different tests assessing physical performance were examined: upper limb strength and lower limb strength, static balance, dynamic balance and mobility showed a tendency to decline over time. On average hand grip strength decreased by 2.2% per month, chair stand test by 3.5%, Berg balance scale by 2%, timed up-and-go test by 2.8%, gait speed by 2.1% and short physical performance battery by 2.8%. A minority of studies have shown an improvement in lower limb muscle strength, endurance and gait speed: in these studies, participants did not attend any kind of physical training but took part to social activities or cognitive interventions.
CONCLUSION: This review shows how physical performance decreases over time in nursing home residents and quantifies their decline. However, in active controls, there was an improvement in some physical performance measures, which indicates that intervention other than exercise might prevent some loss in physical performance.
