그라스톤을 이용한 연부조직가동술이 편마비 환자의 하지 관절 가동범위, 근력, 보행 능력에 미치는 즉각적인 영향에 관한 예비 연구 = The Pilot Study on the Immediate Effects of Graston Technique for Lower Extremity Range of Motion, Muscle Strength, Walking Ability in Hemiplegic Patients

다국어 초록 (Multilingual Abstract)

Background: The purpose of this study was to investigate the effects of Graston technique for lower extremity range of motion (ROM), muscle strength, walking ability in hemiplegia patients. Methods: Twelve subjects participated in this study. The ROM of the knee extension was measured by 90-90 straight leg raise test, the hamstring and quadriceps muscle strength was collected by utilizing a handheld dynamometer. In addition walking speed was evaluated by 10 meter walking test. The group was applied intervention using a Graston instrument for one minute. After intervention, immediate effect was assessed. The significant level was set at ${\alpha}=.05$. Results: The ROM of the knee extension, quadriceps muscle strength and walking speed were significantly increased. Hamstring muscle strength was significantly reduced. Conclusion: The results of this study suggest that Graston instrument technique has the effect of instantaneously flexibility the muscles, and the muscle applied with the technique has weakened, while the muscle of the opposite side has increased the muscle strength. In addition, the muscle flexibility and the walking speed have increased.
