The Effects of Evjenth-Hamberg Stretching on Active Range of Motion of the Hip Joint and the Pennation Angle

The purpose of this study was to investigate the effects of Evjenth-Hamberg stretching on the active range of motion (ROM) of the hip joint and the pennation angle of the semitendinosus muscle. Eighty healthy adults articipated in this study. The active ROM of the hip joint was measured by a goniometer and the pennation angle of the semitendinosus muscle was measured by ultrasonographic imaging (USI). Both ROM and pennation angle were recorded before and after the static stretching and the Evjenth-Hamberg stretching, respectively. Data were analyzed using paired t-test and independent t-test at p<.05. The results were as follows: 1) The active ROM of the hip joint increased significantly after both stretching interventions compared with the baseline (p<.001). However, the active ROM of the hip joint increased significantly in Evjenth-Hamberg stretching compared with static stretching. 2) The pennation angle decreased significantly after both stretching interventions compared with the baseline (p<.001). However, the pennation angle decreased significantly in Evjenth-Hamberg stretching compared with static stretching. 3) Reliability data showed that there was a high consistency in USI measurements ICC=.978. Our findings suggest that the Evjenth-Hamberg stretching was more effective than static stretching in increasing the active ROM of the hip joint and decreasing the pelmation angle of the semitendinosus muscle.
