Movement Quality and Balance Improvement in People With Chronic Low Back Pain Following Trunk Muscle Training
- Conditions
- Chronic Low Back Pain (CLBP)
- Registration Number
- NCT06944730
- Lead Sponsor
- The Hong Kong Polytechnic University
- Brief Summary
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:
1. What are the effect of the training on the participant's movement quality and balance.
2. What are the difference between different types of trunk muscle training on people with CLBP.
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:
1. Do home and in-lab based SE or ITE training, or maintain active daily living over 2 months.
2. Complete the pain and disability questionnaire and do several physical functioning tests while having their trunk and lower limb movement and muscle activation measured.
- Detailed Description
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.

- Primary Outcome Measures
Name Time Method Lower lumbar active range of motion Same day as first day of intervention and within one week after intervention active range of motion of the lower lumbar area during five-repetitions sit-to-stand test.
5RSTS time Same day as first day of intervention and within one week after intervention Time required to complete five-repetitions sit-to-stand with smaller time indicating better performance.
Segmental movement coordination Same day as first day of intervention and within one week after intervention 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.
Segmental movement stability Same day as first day of intervention and within one week after intervention 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.
Postural stability Same day as first day of intervention and within one week after intervention Center-of-pressure normalized mean velocity during Y-balance test. Smaller number indicate greater stability
Postural Control Same day as first day of intervention and within one week after intervention normalized leg reach during y-balance test, with larger number indicating greater postural control.
Perceived pain Same day as first day of intervention and within one week after intervention score from numerical pain rating scale from zero (0) to ten (10), with 0 indicating no pain.
Perceived disability Same day as first day of intervention and within one week after intervention Score based on oswestry disability index scoring from zero (0) to one hundred (100) percent, with zero indicating no disability.
- Secondary Outcome Measures
Name Time Method LAP performance Same day as first day of intervention and within one week after intervention time required to complete the lift and place test with lesser time indicating greater performance
Muscle synergy 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
