운동역학 : 보행 시 폴의 사용이 하지 근육 활동에 미치는 영향 분석 = Electromyographic Analyses of the Effects of Poles during Normal Walking

다국어 초록 (Multilingual Abstract)

The purpose of this study was to determine the effect of the walking pole on the lower limb muscles. Fourteen subjects performed walking exercise at a cadence of 110 beats/min, without pole, with one pole, and with two poles, respectively. For each variable, a one-way analysis of variance (ANOVA) was used to determine whether there were significant differences among the three types of walking. When a significant difference was found in walking type, post hoc analyses were performed using the tukey procedure. A confidence level of p ＜ .05 was used to determine statistical significance.The results showed that significant changes in averaged IEMG values occurred with walking with one pole in the vastus medialis and the lateral gastrocnemius during the IDLS phase, and in the lateral gastrocnemius during the TDLS phase. During the TDLS phase, walking with two poles produced a significantly lower Averaged IEMG values than normal walking in the medial gastrocnemius. The results also found that the peak IEMG activity of the tibialis anterior and the lateral gastrocnemius during ISLS phase for walking with one pole and two poles was significantly lower than the corresponding values in the normal walking, while the walking with one pole and two poles exhibited a significant difference with the normal walking in the medial and lateral gastrocnemius muscles during TDLS phase.In general, the walking with pole influenced the average IEMG and Peak IEMG values of most triceps surae. The use of walking poles alleviated some stress from the ankle joint and allowed reduced activity in triceps surae. This reductions seen walking with poles compared with the normal walking were caused primarily by the force applied to the pole before and after heel strike. It is concluded that walking poles do not seem to exert a more expressive influence in the knee joint than in the ankle joint. This study suggest that further research is necessary to determine the effectiveness of walking poles on the EMG activity of leg muscles during walking on the ramp. These data also serve as a guide for clinicians when considering incorporation of walking poles into patient management.
