The Analysis on Quality Properties of Lower Extremity of Patient with Stroke by the Existence of the Independent Walking

뇌졸중 환자의 독립보행 유무에 따른 하지 근의 질적 특성에 대한 분석

The purpose of this study were to analysis on quality properties of lower extremity of patient with stroke by the existence of the independent walking. We recruited fourteen adults after stroke(7 male, 7 female; mean age, 64y) for our study. The subjects were divided into two groups; independent walking group(3 male, 3 female) and non-independent walking group(4 male, 4 female). We used in this study included a B-mode ultrasonography scanner with a 7.5 MHz linea probe. During the experiment, the subject was seated in the chair. The echogenicity(density, white area index; WAI) of the tibialis anterior and rectus femoris muscles were measured on both sides of the leg. In both of the density and WAI, the tibialis anterior muscle were significant differences between paratic side and non-paratic side, the independent walking and non-independent walking group. However, in both of the density and WAI of the rectus femoris muscle were only significant differences between paratic side and non-paratic side. This study showed that stroke and the independent walking have influenced on quality properties of lower leg. Especially, the independent walking has influenced on the tibialis anterior muscle.
