Factors influencing recovery of walking ability of patients with disuse syndrome and examination of cut-off value

Abstract

[Purpose] To examine the factors that affect recovery of walking ability of patients with disuse syndrome. [Subjects and Methods] The subjects were 52 patients diagnosed as having disuse syndrome. At discharge, they were classified as an independent walking group and a non-independent walking group, and multiple logistic regression analysis was performed on items of physical function, cognitive function, and blood test data to determine the factors influencing gait recovery, and their cut-off values were determined from ROC curves. [Results] Three items, knee extension muscle strength, physical activity, and TP (total protein), were identified as factors related to independent walking, and their cut-off values were: knee extension muscle strength, 0.35 kgf/kg; physical activity amount, 9.9 MET-hours/week; and TP, 6.4 g/dl. [Conclusion] The results suggest that lower limb muscle strength, total physical activity such as walking and rising from a bed, and total protein as a static nutrition index are related to the recovery of gait among patients with disuse syndrome.
