Purpose: In elderly patients with collagen disease, walking ability tends to decrease due to treatment with corticosteroids and long-term hospitalization. The purpose of this study was to investigate the factors related to independent walking in elderly patients with collagen disease. Methods: A total of 65 inpatients, aged ≥65 years with collagen disease, were enrolled in this cross-sectional study. Factors such as independent walking, knee extension muscle strength, one-leg standing (OLS) time, and the Geriatric Nutritional Risk Index (GNRI) were evaluated. Independent walking was evaluated using the functional independence measure (FIM). Patients were divided into the physical assistance group (1–4 points on the FIM) and the no physical assistance group (5–7 points on the FIM). Logistic regression analysis was performed, and cutoff values were calculated. Results: Of the 65 patients, 24 were allocated to the physical assistance group and 41 were allocated to the no physical assistance group. The logistic regression analysis showed the OLS time (odds ratio [OR] = 1.373, 95% confidence interval [CI]: 1.115–1.691, P < 0.01) and GNRI ([OR] = 1.076, 95% [CI]: 1.007–1.150, P < 0.05) as parameters that were associated with a probability of walking independence. Furthermore, according to the receiver operating characteristic curve analysis, the cutoff value for the OLS time was 4.1 s (sensitivity 75.6; specificity 91.7; area under the curve [AUC] = 0.906) and that for the GNRI was 81.7 (sensitivity 61.0; specificity 79.2; [AUC] = 0.713). Conclusions: Altogether, the OLS time and GNRI may be factors related to independent walking in elderly inpatients with collagen disease.
