Effects of a modified Otago exercise program delivered through outpatient physical therapy to community-dwelling older adult fallers in Greece during the COVID-19 pandemic: a controlled, randomized, multicenter trial

Abstract

Background: The pandemic has led to the isolation and social exclusion of older adults and cut them off from any exercise activity. Thus, it is more than ever necessary to implement organized interventions to prevent falls in older people as they remain a global health problem associated with serious injuries, chronic disability, and high costs for the healthcare system. Otago exercise program (OEP) can effectively reduce the number of falls. Aim: To study the effect of a 6 months modified video supported OEP in balance, functional ability, fear of falls and number of falls in Greek older people who have fallen. Method: 150 fallers aged 65–80 years [Median age 70 (67–74), 88.7% women] were divided into two groups (intervention and control). Primary outcomes included changes in Short FES-I, CONFbal scale, 4-Stage Balance test, BBS, TUG test and number of falls, while the secondary outcome consists of the monthly adherence to exercise after the intervention. Analysis of variance with repeated measures was applied. Results: There were statistically significant between groups differences after 6 months with the OEP group to shows improved values in TUG time score (17.8 vs 3.9%, p < 0.001, 95% CI), 4-Stage Balance Test (6.85 vs 1.09%, p < 0.05 95% CI), 30-Second Chair Stand Test 7.35 vs 2.93%, p < 0.001), BBS score (13.27 vs 3.89%, p < 0.001, 95% CI), Short FES-I (35.78 vs 13.01%, p < 0.001, 95% CI) and number of falls (69.12 vs 18.70%, p < 0.001, 95% CI). All the above differences remained statistically significant in the 12 months follow-up (p < 0.05), when differences in the CONFbal score were also observed (p < 0.001, 95% CI). No differences were found in adherence to OEP (p > 0.05). Conclusions: A modified OEP decreases the number of falls, improves the balance and functional ability of older adults and reduces the fear of falling. However, it did not contribute to satisfactory adherence to exercise. Trial registration number/date of registration: NCT04330053/April 1, 2020.
