보행속도의 변화가 만성 뇌졸중 환자 지팡이의 수직력과 마비측 발의 체중지지에 미치는 영향 = The Effect of Change in Gait Speed on Vertical Force of the Cane and Distribution of Affected Foot in the Persons with Chronic Stroke

다국어 초록 (Multilingual Abstract)

Purpose The purpose of this study was to analyze weight bearing of cane and affected foot at different speeds during walking. Methods Thirteen subjects (6 males, 7 females) with stroke enrolled in the study. A foot sensor and an instrumented cane were integrated to analyze the vertical peak force on the affected foot and the cane. Results The applied vertical peak force on the cane were 12.02±4.80% (slow speed), 7.97±3.95% (comfortable speed), and 6.86±3.30% (fast speed) body weight, respectively. The results indicated significantly lower vertical peak force on the affected foot in the low speed walking condition when compared to the fast walking (p<.05) and the comfortable walking (p<.05) conditions. The correlations between TUG and vertical peak force on the cane and affected foot were .71, and -.70 (p<.01). There was a higher correlation between the vertical peak force on the cane and affected foot were -.87(p<.01). Conclusion In conclusion, slower walking speed applied greater vertical peak force on the cane, On the contray, slower walking speed applied less vertical peak force on the affected foot. Further studies, duration of force should be measured at different speeds during walking in lower and higher functioning hemiparetic subjects, as its use may mask underlying gait impairment.
