Inclusion criteria

Inclusion criteria: The following participant will be included into this study: 1. If they are diagnosed of non-specific chronic low back pain with and without pain radiating to one or both lower limbs. 2. If pain severity is greater than or equal to five (5) on the numerical pain rating scale.

Exclusion criteria

Exclusion criteria: The participants will be excluded from the study if they have: 1. History of recent trauma to the back, pelvis, hip and knee. 2. They are pregnant. 3. History of cognitive impairment. 4. Spinal infections (epidural abscess, discitis neuralgia). 5. Inflammatory conditions (Rheumatoid arthritis, ankylosing spondylitis). 6. Neurological disorders.

Primary

Measure	Time frame
1. Numerical pain rating scale The Numeric Pain Rating Scale (NPRS) is a one-dimensional measure of pain intensity in adults, including those with chronic pain due to rheumatic diseases. The NPRS is a segmented numeric version of the visual analog scale (VAS) in which the participant will select a whole number (0–10 integers) that best reflects the intensity of his/her pain. The common format is a horizontal bar or line. Numerical Pain Rating Scale is anchored by terms describing pain severity extremes. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. “no pain”) to '10' representing the other pain extreme (e.g. “pain as bad as you can imagine” or “worst pain imaginable”).	—

Measure	Time frame
INSOMNIA SEVERITY INDEX (ISI) This questionnaire has been designed with reference to the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV) criteria for insomnia and is a reliable and valid measure containing seven items to quantify perceived insomnia severity (initial, middle, terminal), dissatisfaction with current sleep pattern, interference with daily functioning, noticeability of sleep impairment attributed to the sleep problem, and degree of distress or concern raised by the sleep problem (Morin 1993; Bastien et al, 2001). The statements are scored on 4-point likert-scales (‘0’ not at all ‘4’ extremely) generating a total score (range 0-28), indicating clinical insomnia severity (0-7 points no clinically significant insomnia; 8-14 points sub threshold insomnia (mild); 15-21 points clinical insomnia (moderate); 22-28 points clinical insomnia (severe). Evaluation indicates that the Insomnia Severity Index is a reliable and valid instrument to quantify perceived insomnia severity and it is likely to be a clinically useful tool as a screening device or outcome measures in insomnia treatment research, internal consistency is 0.90 (Cronbach alpha rating). ;OSWESTRY DISABILITY QUESTIONNAIRE This is a questionnaire designed to give information on how the back or leg is affecting ability to perform everyday life and it was designed to assess the functional disability level of the low back pain patients. The subscales consist of ten sections. Section 1 measures pain severity, section 2 measures personal care, section 3 measures lifting, section 4 measures walking, sections 5,6,7,8,9,10 measures sitting, standing, sleeping, sex life, social life and travelling respectively. For each section the total possible score is 5. If the first section is marked, the section score = 0, if the last statement is marked, the section is scored 5 and total score is calculated.;SF- 36 QUALITY OF LIFE QUESTIONNAIRE The Short Form (36) Health Survey is a 36-item, patient-	—
