The goal of this project is to assess if Chronic Low Back Pain (CLBP) participant's movement quality and balance variables can change after training that decreases their pain and disability. It will also compare the difference between structural exercise (SE) and isolated trunk exercise (ITE). The main questions it aims to answer are:
Researchers will compare SE, ITE and control. Control group will receive back school education that was shown not to be effective in reducing pain and disability.
Participants will:
Both ITE and SE training are equalized in terms of training intensity based on rate of perceived exertion, training duration per session, training frequency, and intervention period. Training intensity measurement does not use other methods of quantification as ITE training does not increase heart rate or blood lactate significantly regardless of the intensity.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Structural Exercise | Experimental | Single armed dumbbell row, push up and single legged deadlift exercises, done three times per week for eight weeks |
|
| Isolated Trunk Exercise | Experimental | Plank, side bridge, and bird dog isometric holds, done three times per week over eight weeks training |
|
| Control | Sham Comparator | Back school education where participants are taught about healthy seating position, how to carry loads, and maintaining an active daily lifestyle. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Structural Exercise | Behavioral | Multi-joint limb movement with force vector through the spine. The spine is held at neutral position |
|
| Measure | Description | Time Frame |
|---|---|---|
| Lower lumbar active range of motion | active range of motion of the lower lumbar area during five-repetitions sit-to-stand test. | Same day as first day of intervention and within one week after intervention |
| Segmental movement coordination | Lumbar-to-pelvis and pelvis-to-femur movement coordination as quantified by mean absolute relative phase angle during five-repetitions sit-to-stand. Smaller number indicates greater coordination between the two segments. | Same day as first day of intervention and within one week after intervention |
| Segmental movement stability | lumbar-to-pelvis and pelvis-to-femur movement stability as quantified by deviation phase during five-repetitions sit-to-stand. Greater number indicates lesser segmental movement stability. | Same day as first day of intervention and within one week after intervention |
| Postural stability | Center-of-pressure normalized mean velocity during Y-balance test. Smaller number indicate greater stability | Same day as first day of intervention and within one week after intervention |
| Postural Control | normalized leg reach during y-balance test, with larger number indicating greater postural control. | Same day as first day of intervention and within one week after intervention |
| Perceived pain | score from numerical pain rating scale from zero (0) to ten (10), with 0 indicating no pain. | Same day as first day of intervention and within one week after intervention |
| Measure | Description | Time Frame |
|---|---|---|
| LAP performance | time required to complete the lift and place test with lesser time indicating greater performance | Same day as first day of intervention and within one week after intervention |
| Muscle synergy |

| Isolated Trunk Exercise | Behavioral | Holding the spine in neutral position with no limb movement, with static loading through the spine |
|
| Back school | Behavioral | Patient education that has been proven to not be effective and has been used as control in past low back pain intervention studies |
|
| Perceived disability | Score based on oswestry disability index scoring from zero (0) to one hundred (100) percent, with zero indicating no disability. | Same day as first day of intervention and within one week after intervention |
| 5RSTS time | Time required to complete five-repetitions sit-to-stand with smaller time indicating better performance. | Same day as first day of intervention and within one week after intervention |
Muscle synergy as measured by the surface electromyography (SEMG) output of the latissimus dorsi, longissimus pars thoracis, longissimus pars lumborum, external oblique, rectus abdominis, gluteus maximus and biceps femoris muscle both on left and right side during all functional tests. SEMG signals would then be processed using non-negative matrix factorization to find the underlying muscle synergies
