Objective : 1) Quantify the physical function (PF) and fatigue level (FL) in community-dwelling older adults (CDA) with high fall risk (HFR); and, 2) Investigate correlations of PF with FL and other WHO-ICF body function components (BF): anxiety, depression, and sleep disturbance (SD) and with clinician-derived performance-based assessments (PBA)
Design: Retrospective cross-sectional study
Setting : PMR clinic
Participants : 25 CDA [13 males; mean age (SD) male/female 78(7) / 74(7) years] were identified as HFR, defined as CDC-STEADI score >/=4
Main Outcome Measures: PROMIS-29v2.0-Physical-Function (PrPF) sub-scale quantified PF, and PROMIS-29v2.0-Fatigue (PrF) measured FL. Other studied BF included PROMIS-57v2.0-sleep-disturbance (SL), anxiety, and depression sub-scales. PBA included: 6-Minute Walk Test (6MWT) as a measure for gait speed, Berg-Balance-Scale (BBS) for balance/coordination, Dynamic-Gait-Index (DGI) for endurance/power, dynamometer for strength, and skeletal muscle index (by bioelectric impedance analysis) for muscle composition.
Results: Data met normality assumptions; hence parametric procedures were used. Mean (SD) scores were (male/female): STEADI 8.3 (4)/7.7 (3), PrPF T-score 34(9)/32(6), PrF T-score 58(11)/57(7), 6MWT (mph) 1.8(0.39)/1.6(0.55), and DGI (maximum score 24) 17(4)/19(3). PF positively correlated with age (r=0.39;p=0.055) and DGI (r=0.579;p=0.024), while fatigue positively correlated with anxiety (r=0.605;p=0.005), depression (r=0.581;p=0.007) and SL (r=0.61;p=0.002). STEADI negatively correlated with age (r=-0.57;p=0.003), PF (r=-0.393;p=0.052), and DGI (r=-0.569;p=0.027).
Conclusions: CDA with HFR tend to have severely low physical function, have mild fatigue, and be clinically slow. Their PF is significantly associated with age and power/endurance, while their fatigue is associated with other BF(s) – mood and sleep disturbance.
The study supports the importance of studying inter-relationships of fall risk with the WHO-ICF components: body functions (specifically anxiety/depression, fatigue, sleep) and activity limitations when assessing falls in older adults. Future research is needed to determine inter-relationships between BF and PF in other geriatric syndromes such as osteoporosis.
