AIM

Life-space mobility (LSM) restriction is a serious issue among older adults using home-visit rehabilitation (HR). This study evaluated physical function, transportation, and other factors not comprehensively tested in previous studies and examined factors associated with the restriction of LSM among older adults using HR.

METHODS

This cross-sectional multi-center study recruited 88 HR users (49 men, 39 women, mean age 79.0 [±7.8] years) living in urban and rural areas from August to October 2020. We administered the Life-Space Assessment (LSA), the Self-Efficacy Scale on Going out among community-dwelling Elderly (SEGE), grip strength, a 30-s chair stand test, Bedside Mobility Scale, Functional Independence Measure, Frenchay Activities Index (FAI), Ikigai-9, and Home and Community Environment (HACE) test. Participants were divided into two groups based on the cut-off value of the LSA scores. In the logistic regression analysis, the dependent variable was LSA scores ≤30, and the independent variables were measured based on objective evaluation items and adjusted for confounding factors (age, sex, and frequency of use of day-care services).

RESULTS

Restriction of LSM was significantly associated with FAI (odds ratio [OR] = 0.817, 95% confidence interval [CI] = 0.706-0.945), HACE facilitators (OR = 1.558, 95% CI = 1.168-2.079), and living alone (OR = 12.822, 95% CI = 1.202-136.716).

CONCLUSION

Restriction of LSM is associated with environmental factors, such as assistive devices and household composition, and ability to engage in instrumental activities of daily living. Our findings indicate a great need for focusing on these factors among home-care older adults receiving HR. Geriatr Gerontol Int 2023; 23: 722-728.
