Effect of Gluteus Maximus Strengthening on Back Pain, Range Of Motion and Endurance in Desk-Job Workers With Chronic Low Back Pain

the purpose of study to learn the effect of strengthening of gluteal maximum on desk-job workers who have chronic low back pain on there pain and range of motion, 40 worker (20 males - 20 females) classified equally to two groups : Group A : treated with traditional methods which contains of Electrotherapy ( TENS or Interferential for 20 min. ) , postural education and active range of motion for lumbar spine . while Group B: treated by traditional methods in additional to gluteus maximum strengthening both groups recessive treatment 3 times per week for 4 weeks.

Evaluation:

• used VAS to asses pain level pre and post treatment,
• Universal goniometer used to asses range of motion of extension and flexion of lumbar spine pre and post treatment.
• Biering-Sorensen test used to asses back muscles pre and post-treatment.
• Modified schober's test used to asses the distance between lumbar vertebrae during flexion pre and post treatment
