NCT01861418

Brief Summary

The purposes of this study are:

  1. 1.To examine the within-day and between-day test-retest reliability of a testing protocol measuring the back and hip muscles fatigability using EMG median frequency
  2. 2.To examine the immediate and the carry-over effects of the lumbopelvic manipulation on the EMG median frequency of the lumbar multifidus (MULT), gluteus medius (GMED) and gluteus maximus (GMAX) muscles in patients with chronic low back pain (CLBP)
  3. 3.To compare the fatigability levels of the MULT, GMED and GMAX muscles by measuring the EMG median frequency between the participants who will receive lumbopelvic manipulation.
  4. 4.The testing protocol using EMG median frequency as a fatigue indicator for MULT,GMED and GMAX muscles will have good (ICC ≥ 0.80) within-day and between-day test-retest reliability.
  5. 5.The fatigability level of the MULT, GMED and GMAX muscles will significantly decrease immediately after the lumbopelvic manipulation and will be maintained over two to four days following the manipulation.
  6. 6.The fatigability of the MULT, GMED and GMAX muscles will significantly decrease after the intervention in the manipulation group while no change will occur in the placebo group.

Outcome Measures

Primary Outcomes (1)

  • Amount of Change in Muscles Endurance

    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).

    Baseline, Immediately, 15-minutes, 30-minutes, and two to four days after the intervention

Secondary Outcomes (1)

  • Amount of Change in Pain Level

    Baseline, immediately, 15-minutes, 30-minutes, and two to four days after the intervention

Study Arms (2)

Sham manipulation

PLACEBO COMPARATOR

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.

Other: Sham manipulation

Lumbopelvic Manipulation, Chicago

EXPERIMENTAL

Each participant will lie in supine position. The treating investigator (TI) will stand opposite of the low back pain. Participant will clasp his/her hand behind the neck. TI will side bend the participant's spine toward non-painful side, reach through participant's hands and perform a spinal rotation away from the painful side. 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.

Other: Lumbopelvic Manipulation

Interventions

Participant will lie in supine position. The treating investigator (TI) will stand on opposite side of low back pain. Participant will clasp his/her hand behind the neck. TI will side bend participant's spine towards non-painful side. TI will reach through participant's hands and perform spinal rotation away from painful side. TI's other hand will be placed over anterior superior iliac spine (ASIS) of painful side. TI will take up the slack and maintain pressure on the ASIS for 5-10 seconds and ask the 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 participant and TI will proceed and apply a high-velocity low-amplitude posterior thrust force over the ASIS.

Also known as: Chicago Manipulation Technique
Lumbopelvic Manipulation, Chicago

Each participant will be asked to lie in a supine position. The treating investigator 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 treating investigator will side bend the participant's spine towards the non-painful side to mid-range. The treating investigator will reach through the participant's hands and perform a spinal rotation away from the painful side to the mid-range. The treating investigator's other hand will be placed over the anterior superior iliac spine (ASIS) of the painful side.
