Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • One hundred persons with non specific low back pain will be recruited consecutively from the Specialist Outpatient Department (SOPD) of Physiotherapy Department of Queen Elizabeth Hospital. Subjects will be included in the study if they presented with symptom duration of greater than three months with no radiological abnormality detected.

Who cannot join

  • All subjects should be able to provide informed consent and demonstrate sufficient ability to tolerate the experiment procedure to avoid aggravation of symptoms during the experiment procedures. Subjects will be excluded if they have any major orthopedic, neurological, circulatory or respiratory conditions, a history or family history of epilepsy, recent or current pregnancies, and previous surgery to the abdomen or back. The back pain history in the previous year will be documented for those eligible subjects.

About this study

Official title: Clinical Electrophysiology Assessment for Rehabilitation Progress of Low Back Pain Patients

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

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Baseline on enrollment and after six weeks physiotherapy

Secondary outcomes (1)
  1. 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.

    Measured: Baseline on enrollment and after six weeks physiotherapy

Questions about this trial

What is this clinical trial studying?

A study testing physiotherapy rehabilitation in people with Non Specific Chronic Low Back Pain, run by The University of Hong Kong at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Numeric Pain Rating Scale (time frame: Baseline on enrollment and after six weeks physiotherapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2019.
