Brief summary (from the registry)
Objective: This study will be conducted to investigate the relationship between the amplitude of posterior oblique sling muscles; ipsilateral gluteus maximus (GM) and contralateral latissmus Dorsi (LD), and the amount of anterior translation of humeral head (ATHH) of the contralateral glenohumeral joint (GHJ) in subjects with unilateral chronic low back pain (CLBP) during ipsilateral prone knee extension (PHE) test. Methods: The study will be conducted on thirty subjects (15 patients with CLBP and 15 healthy subjects). Ipsilateral GM and contralateral LD amplitude will be recorded by surface EMG during PHE of the limb at the painful side and correlated to ATHH of contralateral GHJ as measured by ultrasonography. Hypothesis: There won't be a significant relationship between the amplitude of posterior oblique sling muscles (GM and contralateral LD) during PHE for the ipsilateral leg and the amount of ATHH of the contralateral GHJ in patients with unilateral CLBP.

Eligibility criteria
Show eligibility criteria (verbatim from the registry)
Inclusion Criteria for CLBP group: 1. Patients age between 20-50yrs 2. Patients with chronic low back pain (pain \> 3 months). 3. Patients with unilateral symptoms (facet, disc, SIJ dysfunction) will be referred by an orthopedic physician with or without referral to the leg. Inclusion Criteria for the healthy control group: 1\. matched controls in terms of age, weight, height, and BMI. Exclusion Criteria for both groups: 1. History of shoulder pain 3 months ago. 2. History of any shoulder pathology. 3. Congenital pathology affecting the spine or shoulder. 4. Any neurological disorder. 5. Non-mechanical LBP (e.g., fracture, malignancy, infection) 6. Difficulty performing the PHE task because of weakness in the GM or the test provokes pain. 7. BMI 30 or higher as fat tissue may decrease the ability to measure surface EMG activity
