Relationship between the weight-bearing ratio of the lower limb and usage of walking aids for elderly patients in care facilities

Abstract

[Purpose] This study focused on elderly patients in care facilities with various walking types. We examined whether the weight-bearing ratio of the lower limb (lower limb WBR) can help in determining the requirement and type of walking aids. [Method] Sixty-eight elderly patients admitted in care facilities were enrolled in this study and classified into three groups: caneless, T-shaped cane, walking vehicle. The lower limb WBR (sitting-/-standing), grip strength, one leg standing, 10-m Walking test, FRT, TUG were measured. One-way ANOVA was used to examine each target group by walking type,and multiple regression analysis was used to examine the factors affecting lower limb WBR. [Result] All the measurement had a significant impact on each target group according to the walking type. Moreover the lower limb WBR (standing) (β=0.418, p<0.001) and grip strength (β=0.386, p<0.001) were extracted as significant related factors for lower limb WBR (sitting). One-leg standing (β=0.214, p<0.039) and lower limb WBR (sitting) (β= 0.526, p<0.001) were extracted as significant related factors for lower limb WBR (standing). [Conclusion] The lower limb WBR was an effective aid in the clinical decision-making to select walking aids.
