Evaluating Changes of Spino-pelvic Radiological Parameters During Muslim Prayer Positions

Plain radiographs, including the lumbar spine, pelvis, and the upper half of both femora, will be obtained using the lowest radiation dose possible. The radiographs will be obtained in five positions representing the Muslim Prayers positions, namely 1-standing, 2-Sitting in 90 degrees (both 1 and 2 are the standard positions obtained in all previous studies), 3-bowing (Ruku), 4-prostration (sujud), and 5-sitting with knees bent (Tashahud).
