An interventional study of physiotherapy rehabilitation in Non Specific Chronic Low Back Pain, sponsored by The University of Hong Kong. Completed at 1 site in China. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2019-04-16.

Non specific chronic low back pain (LBP) is a debilitating disorder characterized by tremendous personal and socioeconomic impact, with long-term sick leave, low quality of life, and very high financial costs. Evidence suggests that patients with non specific LBP presented with altered muscle activity pattern when compare with healthy people. It has been reviewed that exercise therapy was effective for modulation of muscle dysfunction in chronic low back pain. However, there is a lack of objective assessment of the pain relief in low back pain rehabilitation. Clinical application of surface electromyography (EMG) may provide a quantitative and objective tool to evaluate the rehabilitation outcome in patients with non specific chronic low back pain before and after treatment.
Objectives: To verify the usefulness of surface electromyography (EMG) in low back pain (LBP) rehabilitation assessment.
Setting: Out-patient physiotherapy musculoskeletal rehabilitation
Participants: One hundred adults with non specific chronic low back pain (LBP) will be recruited.
Methodology: A prospective correlation study between clinical examination and electrophysiology assessment. This project will perform carefully with a definitive chronic low back pain (LBP). Firstly, we will compare the surface EMG features from patients with LBP to normal data. In addition, the changes in electrophysiology assessment will be compared with clinical assessment by Numeric Pain Rating Scale (NPRS). This allows us to verify the potential clinical application of surface EMG features in physiotherapy progress assessment.

Exclusion Criteria:
Patients with chronic low back pain to be measured with Numeric Pain Rating Scale (NPRS).
Other: physiotherapy rehabilitation
All subjects will receive a course of conventional physiotherapy that incorporating components of pain relief and functional restoration with the use of electrotherapy and exercise therapy for twelve sessions twice weekly in six weeks guided by a registered physiotherapist in Hong Kong.
Numeric Pain Rating Scale
Intensity of self-reported pain was measured using a Numeric Pain Rating Scale (NPRS) anchored with 'no pain' at 0 and 'worst pain imaginable' at 10. Subjects rated their average pain over the preceding month prior to motor training, and rated their average pain across the final week of motor training.
Time frame: Baseline on enrollment and after six weeks physiotherapy
surface electromyography (EMG)
Disposable surface EMG electrodes will be attached in array to the right and left lumbar erector spinae (LES) muscles, approximately 2 cm lateral to the L3 spinous process. Root mean square amplitude of surface EMG measured was calculated and flexion-relaxation ratio in sitting was formulated by dividing the average surface EMG activity in upright sitting by the average surface EMG activity in slumped sitting.
Time frame: Baseline on enrollment and after six weeks physiotherapy
