Background: Nonspecific chronic low back pain is the most common problem that can cause economic and social problems for an individual. Although there were, many studies have reported the changes in the lumbopelvic muscles activity and scapular position in nonspecific chronic low back pain patients but it still debated. purpose: This study was conducted to investigate the electromyographic activity of lumbopelvic muscles and scapular position in nonspecific chronic low back. Subjects: Thirty nonspecific chronic low back pain male patients and thirty healthy male subjects were recruited and assigned into 2 groups .Group A (study) with mean age 29±5.53 years ,mean weight 70.94 ±7.39 Kg , mean height 169.73 ±5.84 cm and mean BMI 24.61±2.18 kg/m² .Group B (control) with mean age 31.03± 6.31 years , mean weight 70.66 ±9.95 Kg,mean height 171 ±6.05 cm and mean BMI 24.12 ± 2.76 kg/m²). Methods: Assessment was conducted by surface electromyography (MyoTrac infiniti System T 9800) to assess muscle activity for right and left latissimus dorsi and gluteus maximus muscles and inclinometer to assess right and left scapular upward rotation from (neutral position, 45{u02DA}abduction, 90{u02DA}abduction, 135{u02DA}abduction and end range abduction) positionson in both conditions (NSCLBP and scapular dyskinesia ) prior to formulate a treatment plan
