Objective To evaluate the effect of a contralateral shoe-lift and ipsilateral leather outsole on the energy consumption in hemiplegic gait. Method Ten hemiplegic patients who could walk independently were enrolled. Using portable ergospirometer (K4b2, Cosmed, Italy), quantitative evaluation of oxygen consumption under varying shoes conditions was done: 1) regular shoes 2) a half-inch shoe-lift on the sound side 3) a half-inch shoe-lift on the sound side and leather outsole on the plegic side. The evaluation distance was 20 meter on comfortable walking speed. Results The oxygen consumption was significantly decreased after the application of shoe-lift compared with regular shoes (p<0.01), and the oxygen consumption was least with the application of shoe-lift and leather outsole (p<0.05). This effect was prominent in subject with poor muscle power in hemiplegic lower extremity. The walking speed was also increased with shoe-lift and leather outsole (p<0.05). Conclusion The results of this study demonstrate that proper shoes modification can reduce the energy consumption in hemiplegic gait and can lead to more efficient functional ambulation. |
