The ECEALT Chronic Low Back Pain Study
Study Details
Study Description
Brief Summary
The primary objective of this double-blind randomized control trial (RCT) is to evaluate the clinical effectiveness of LLLT as adjunctive therapy to standard exercise treatment in patients with non-specific chronic LBP. Specifically, the study will aim to evaluate the effectiveness of adjunct LLLT in the reduction of pain in patients as well as determine its long-term functional outcomes.

Detailed Description
Low back pain (LBP) is one of the most common musculoskeletal disorders and the leading cause of years lived with disability worldwide with significant socioeconomic impacts. Around 10-15 % of LBP patients develop chronic symptoms lasting more than 3 months, and this is considered chronic, with the causes often being "non-specific" with no identifiable causes. Despite the availability of medication-based protocols, the management of non-specific chronic LBP (NSCLBP) is an increasing challenge to clinicians and their patients. Adjunctive therapy can play an important role in the treatment of NSCLBP. In recent decades, low-level laser therapy (LLLT) has been widely used to relieve pain caused by different musculoskeletal disorders. Though widely used and reported as a safe, non-invasive treatment with minimal side effects; reported therapeutic outcomes of LLLT are varied and conflicting, due in part to methodological concerns, lack of data and unclear results.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Low Level Laser Therapy + standard exercise therapy This group of participants will first receive the standard therapy of strengthening and stretching exercises followed by the Low Lever Laser Therapy. |
Device: BTL 4110 Smart Laser Therapy Equipment (BTL Industries Ltd, United Kingdom (UK))
Participants will receive 12 LLLT sessions during the course of the trial, thrice weekly for 4 consecutive weeks. Doses will be as per the recommendations of the Wold Association of Laser Therapy.
Other: Standard Exercise Therapy
Exercise therapy will consist of strengthening and stretching exercises. At each visit, participants will perform each of the exercises under the supervision of a licensed physiotherapist.
|
| Sham Comparator: Sham Low Level Laser Therapy + standard exercise therapy This group of participants will first receive the standard therapy of strengthening and stretching exercises followed by a sham Low Level Laser Therapy (LLLT). The laser equipment will be deactivated and not switched on. |
Device: BTL 4110 Smart Laser Therapy Equipment (BTL Industries Ltd, United Kingdom (UK))
Participants will receive 12 LLLT sessions during the course of the trial, thrice weekly for 4 consecutive weeks. Doses will be as per the recommendations of the Wold Association of Laser Therapy.
Other: Standard Exercise Therapy
Exercise therapy will consist of strengthening and stretching exercises. At each visit, participants will perform each of the exercises under the supervision of a licensed physiotherapist.
|
| Active Comparator: Standard Exercise Therapy Trial participants in this group will only receive the standard exercise therapy. The exercise therapy will consist of strengthening and stretching exercises. |
Other: Standard Exercise Therapy
Exercise therapy will consist of strengthening and stretching exercises. At each visit, participants will perform each of the exercises under the supervision of a licensed physiotherapist.

Outcome Measures
Primary Outcome Measures
- Change in Pain using the Quadruple Visual Analog Scale [Weeks 1, 2, 3, 6, 8, 12, 26 and 52]
The change in Pain measured using the Quadruple Visual Analog Scale (QVAS) measured at weeks 1, 2, 3, 6, 8, 12, 26 and 52. Pain reduction measured on a 10-point Likert scale from 0 (no pain) to 10 (worst possible pain). Overall score interpreted based on QVAS scoring manual of <50(Low intensity) and >50 (high intensity).
- Change in Pain using the McGill Pain Questionnaire [Weeks 1, 2, 3, 6, 8, 12, 26 and 52]
The change in Pain measured using the McGill Pain Questionnaire measured at weeks 1, 2, 3, 6, 8, 12, 26 and 52. Pain reduction assessed based on an overall score ranging from 0 (would not be seen in a person with true pain) to 78(seen in a person with the greatest pain).
- Change in Pain using the Brief Pain Inventory [Weeks 1, 2, 3, 6, 8, 12, 26 and 52]
The change in Pain measured using the Brief Pain Inventory measured at weeks 6, 8, 12, 26 and 52. Pain reduction assessed based on an overall score ranging from 0 (no pain or does not interfere) to 10(pain as bad as be imagined or completely interferes).
Secondary Outcome Measures
- Reliance on medication for pain management using the Brief Pain Inventory [Weeks 1, 2, 3, 6, 8, 12, 26 and 52]
Reliance on medication for pain management measured using the Brief Pain Inventory (short form) measured at weeks 6, 8, 12, 26 and 52. Pain reduction assessed based on an overall score ranging from 0% (no relief) to 100% (complete relief).
- Mean Pain Free Days/Months using the Brief Pain Inventory [Weeks 1, 2, 3, 6, 8, 12, 26 and 52]
Mean Pain Free Days measured using the Brief Pain Inventory measured at weeks 6, 8, 12, 26 and 52. Pain reduction assessed based on an overall score ranging from 0 (no pain or does not interfere) to 10(pain as bad as can be imagined or completely interferes).
- Fear of Pain measured using the McGill Pain Questionnaire [Weeks 1, 2, 3, 6, 8, 12, 26 and 52]
Fear of pain measured using the McGill Pain Questionnaire at weeks 1, 2, 3, 6, 8, 12, 26 and 52. Fear of Pain assessed on a 3-point scale from 1(fearful), 2 (frightful) or 3 (terrifying).
- Frequency of Low Back Pain Episodes assessed using patients personal daily pain records [Weeks 1, 2, 3, 6, 8, 12, 26 and 52]
Frequency of LBP episodes during trial measured using patients personal daily pain records at weeks 1, 2, 3, 4, 6, 8, 12, 26 and 52. Each episode of pain recorded as a single occurrence.
- Mean number of days absent from work measured using patients personal daily pain record [Weeks 1, 2, 3, 6, 8, 12, 26 and 52]
Mean number of days absent from work measured using patients personal daily pain records at weeks 1, 2, 3, 4, 6, 8, 12, 26 and 52. Not being able to work completely due to pain within a work day recorded as a single day, while working for less than 4 hours due to pain recorded as partial work day.
