Abstract

This study was conducted to confirm the effect of vibration on muscle activity in IASTM. The subjects were 20 healthy adults. The intervention applied in this study was IASTM applied to the biceps brachii muscle. In the case of the experimental group, unlike the control group, the vibration function was turned on when IASTM was applied. The interventions for each group were applied, and the muscle activity of the biceps brachii muscle was measured before and after the intervention. All measured values were calculated as %MVIC values, dependent t test and independent t test were performed and analyzed for comparisons. As a result of this study, only in the control group, the muscle activity of the biceps brachii muscle after the intervention was significantly decreased compared to before the intervention. When vibration is applied together with IASTM, the relaxation effect is reduced, which is considered to be inappropriate for treatment.

본 연구는 도구를 이용한 연부조직 가동술 적용 시 진동의 유무가 근활성도에 미치는 영향을 확인하고자 수행되었다. 대상자는 건강한 성인 20명이다. 본 연구의 적용된 중재는 위팔두갈래근에 적용된 연부조직 가동술이며, 실험군의 경우는 대조군과 달리 연부조직 가동술 적용 시 진동 기능을 켜 적용하였다. 모든 대상자는 각 집단에 해당하는 중재를 적용 받았으며, 중재 전과 후로 위팔두갈래근의 근활성도를 측정하였다. 측정된 모든 값은 %MVIC 값으로 계산되었고, 대응 t검정과 독립 t검정을 수행하여 이를 분석하였다. 본 연구의 결과 대조군에서만 중재 적용 후 위팔두갈래근의 근활성도가 중재 적용 전에 비해 유의하게 감소하였다. 본 연구의 결과에 따르면, 도구를 이용한 연부조직 가동술 적용 시 진동이 함께 적용되면 이완 효과를 감소시켜 치료에 적절치 못한 것으로 사료 된다.
