Each participant will lie in a supine position. The treating investigator (TI) will stand on the opposite side of the low back pain. Then, the participant will be asked to clasp his/her hand behind the neck. The TI will side bend the participant's spine towards the non-painful side, reach through the participant's hands and perform a spinal rotation away from the painful side. The TIs other hand will be placed over the anterior superior iliac spine (ASIS) of the painful side. Lastly, the TI will take up the slack and maintain the pressure on the ASIS for 5-10 seconds and ask the participant whether he/she can tolerate the pressure. If the participant can tolerate the pressure for at least 5 seconds. Then, the subjects will be re-positioned to the starting position.

TI's other hand will be placed over the anterior superior iliac spine (ASIS) of the painful side. The TI will take up the slack and maintain pressure on the ASIS for 5-10 seconds and ask participant whether he/she can tolerate the pressure. If participant can tolerate the pressure for at least 5 seconds, verbal permission will be obtained from the participant and the TI will proceed and apply a high-velocity low-amplitude posterior thrust force over the ASIS.

electromyographic (EMG) median frequency will be used to determine the endurance of the gluteus maximums, gluteus medius and the lumbar multifidus muscles. The EMG median frequency will be measured in Hertz (Hz).

Pain Visual Analogue Scale (VAS) will be used in this study. Participants will be asked to rate their pain level on a 10-cm horizontal line which is marked on the left end "No pain" and on the right end "Extreme pain". Then, the pain level for a specific participant will be determined by measuring the line from the "No pain" end to the mark placed by the participant.
