简要总结
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:
- What are the effect of the training on the participant's movement quality and balance.
- 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:
- Do home and in-lab based SE or ITE training, or maintain active daily living over 2 months.
- Complete the pain and disability questionnaire and do several physical functioning tests while having their trunk and lower limb movement and muscle activation measured.
详细描述
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.

结局指标
主要结局
Segmental movement stability
时间窗: 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.
Lower lumbar active range of motion
时间窗: 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
时间窗: 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
时间窗: 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.
Postural stability
时间窗: 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
时间窗: 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
时间窗: 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
时间窗: 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.
次要结局
- LAP performance(Same day as first day of intervention and within one week after intervention)
- Muscle synergy(Same day as first day of intervention and within one week after intervention)
