This study aimed to identify alterationsin the thickness of the psoas major and the pelvic tilt angle in response to deep friction massage (DFM), modified Thomas stretching (MTS), or muscle energy technique (MET). The thickness of the psoas major was measured by ultrasound while that of the pelvic tilt angle was measured according to marks on the anterior-superior and posterior-superior iliac spines. This study involved 45 male subjects with noorthopedic or neurological disease. All subjects volunteered to participate in the study. In the MTS group, the subjects completed 10 repetitions of 10-second stretches. In the DFM group, friction was applied for 10 seconds at a frequency of 1 Hz. In the MET group, 7 seconds of isometric contraction and 10 seconds of stretching were applied. Pre- and post-treatment changes in the pelvic tilt angle were significant in the three groups (p<.05). Pre- and post-treatment changes in psoas major thickness were significant in the MTS (p<.05) and MET groups (p<.05) but not in the DFM group (p>.05). There were no significant pre- and post-treatment changes in pelvic tilt angle and psoas major thickness between the three groups (p>.05). This study compared three types of interventions to determine the most effective method for psoas major stretching. Our results can be used to treat patients with psoas shortening.
