Effects of Lumbopelvic Manipulation on Neuromuscular Activity of Back & Hip Muscles in Adults With Chronic Low Back Pain
Chronic Low Back Pain
About this trial
This is an interventional treatment trial for Chronic Low Back Pain focused on measuring chronic low back pain, low back pain, lumbopelvic manipulation, Chicago manipulation, EMG median frequency, electromyography, reliability
Eligibility Criteria
Healthy subjects or the reliability phase:
Inclusion Criteria:
- Subjects without any history of back problems
- Subjects without any known pathology.
Exclusion Criteria:
- Any serious spinal condition such as tumor, fracture, or infection,
- Signs of nerve root compression (i.e. straight leg- raise ≤ 45° or diminished reflexes, sensation or lower extremity strength),
- Structural deformity,
- Spondylolithesis ,
- Ankylosing spondylitis
- Spinal stenosis,
- Osteoporosis,
- Previous surgery to the back or the hip, and
- Current pregnancy.
Subjects with Chronic low back pain for both the reliability and the manipulation phases:

Lumbopelvic Manipulation, Chicago
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.

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.
