Effect of Low-level Laser Therapy Versus Shock Wave Therapy on Pain and Function in Patients With Chronic Non-specific Low Back Pain

A significant global source of disability is low back pain. Maladaptive variations in the level of activity in the lumbar musculature are one thing that could possibly contribute to persistent pain.

Treatment and study plan

Low-level laser therapy

Other

Is a form of medicine that applies low-level (low-power) lasers that relieve pain.The effects appear to be limited to a specified set of wavelengths

shock wave therapy

Other

is a non-invasive treatment that stimulates the body's natural healing process. It can relieve pain and promote healing of injured tendons, ligaments, and other soft tissues

Primary outcomes

  1. Oswestry low back disability questionnaire

    Time frame: 30 minutes

    The Oswestry Disability Index (also known as the Oswestry Low Back Pain Disability Questionnaire) is an extremely important tool that researchers and disability evaluators use to measure a patient's permanent functional disability. The test is considered the 'gold standard' of low back functional outcome toolsFor each section the total possible score is 5: if the first statement is marked the section score = 0; if the last statement is marked, it = 5. If all 10 sections are completed the score is calculated as follows: Example: 16 (total scored) 50 (total possible score) x 100 = 32%

    If one section is missed or not applicable the score is calculated:

    16 (total scored) 45 (total possible score) x 100 = 35.5% Minimum detectable change (90% confidence): 10% points (change of less than this may be attributable to error in the measurement)

  2. Back pain functional scale

    Time frame: 20 minutes

    The Back Pain Functional Scale (BPFS) is a subjective scale used to measure the patient's physical function after low back painThis scale consists of a total score of 60. Moreover, the patient's score can be measured from the responses obtained on the Likert scale (0 to 5), and accordingly, a total score is summed up out of 60. Furthermore, the maximum score obtained indicates the maximum physical abilities of the patients. In addition, this scale also has an 'Adjusted score' ranging from 0 (0%)-unable to perform any activity to 60 (100%)-no difficulty in any activity

  3. Visual analogue scale

    Time frame: 5 minutes

    Visual analogue scale (VAS) is a unidimensional measure of pain intensity, used to record patients' pain progression, or compare pain severity between patients with similar conditions.

    Visual analogue scale (VAS) is most commonly a straight 100-mm line, without demarcation, that has the words "no pain" at the left-most end and "worst pain imaginable" (or something similar) at the right-most end.48 Patients are instructed to place a mark on the line indicating the amount of pain that they feel at the time of the evaluation. The distance of this mark from the left end is then measured, and this number is used as a numeric representation of the severity of the patient's pain
