Effects of a Multicomponent Exercise Program on Improving Frailty in Post-COVID-19 Older Adults after Intensive Care Units: A Single-Group Retrospective Cohort Study

Simple Summary Older adult patients with post-COVID-19 syndrome present greater physical impairment accompanied by frailty, which is why multicomponent exercise programs (MEP) are recommended for their positive effects on improving frailty and physical capacity. The aim of this study was to evaluate the effects of a short MEP (Vivifrail; <4 weeks) on the improvement of physical performance and frailty in post-COVID-19 older adults in a hospital setting. Data were collected from the functional gait training program based on selected Vivifrail MEP in a single group, applied to patients admitted with a diagnosis of post-COVID-19 functional impairment. The program was carried out for 3 weeks, with daily sessions lasting 40 min. Patients included were assessed at the beginning and at the end of the protocol on their functionality, strength, balance, gait and coordination, and ability to carry out basic activities of daily living. The results of this study show significant improvements in physical fitness and frailty by means of the MEP applied in its short version (<4 weeks) showing even clinically relevant improvements. The MEP is effective and safe on improving frailty in post-COVID-19 older adult patients. Abstract Background: Older adult patients with post-COVID-19 syndrome present greater physical impairment accompanied by frailty than younger patients, which is why multicomponent exercise programs (MEP) are recommended for their positive effects on improving frailty and physical capacity. The aim of this study was to evaluate the effects of a short MEP (Vivifrail; <4 weeks) on improving frailty in post-COVID-19 older adults after intensive care units. Methods: To develop a retrospective cohort study, data were collected from the functional gait training program based on selected Vivifrail MEP in a single-group and applied to patients admitted with a diagnosis of post-COVID-19 functional impairment. The MEP was carried out for 3 weeks, with daily sessions lasting 40 min. Patients included were assessed at the beginning and at the end of the protocol by using the Short Performance Physical Battery (SPPB), the number of falls in the last year, the number of falls with medical attention, the Timed Up and Go (TUG) test, the presence of dementia, the Trunk Control Test (TCT), the Tinetti balance and gait test, Barthel Index, Medical Research Council Sum Score (MRCSS) and handgrip strength dynamometry. Results: The results of this study show statistically significant improvements in physical fitness and frailty with increases in the Short Physical Performance Battery (Z = 9.12, p < 0.001) by means of the MET applied in its short version (<4 weeks) showing even clinically relevant improvements (>2.5 points). Statistically significant improvements were also found in Medical Research Council Sum Score (Z = 12.345, p < 0.001), Barthel Index Score (Z = 12.272, p < 0.001), Trunk Control Test (Z = 12. 36, p < 0.001), Tinetti–POMA (Z = 12.293, p < 0.001) including the balance (Z = 12.11, p < 0.001), gait (Z = 12.164, p < 0.001) subscales and in the hand dynamometry (Z = 12.172, p < 0.001). Conclusions: The selected Vivifrail MEP is effective and safe for improving frailty in post-COVID-19 older adult’s patients.
