The findings of this study support the use of PA mobilization and a press-up exercise for improving lumbar extension in people with nonspecific low back pain. Although statistically significant within-group changes in pain were detected, the clinical meaningfulness of these changes is questionable.

An intensive, progressive exercise program combined with education reduces disability and improves function in patients who have undergone a single-level lumbar microdiskectomy.

T T CONCLUSION:The results of the present study demonstrate preferential activation of the superior portion of the gluteus maximus during exercises that incorporate elements of hip abduction and/ or external rotation. In contrast, exercises that primarily involve hip extension target both portions of the gluteus maximus to a similar extent.

Background: Low back pain remains a costly quality-of-life-related health problem. Microdiscectomy is often the surgical procedure of choice for a symptomatic, single-level, lumbar disc herniation in younger and middle-aged adults. The question of whether a postmicrodiscectomy exercise program enhances function, quality of life, and disability status has not been systematically explored. Thus, the overall purpose of this study is to assess immediate and long-term outcomes of an exercise program, developed at University of Southern California (USC), targeting the trunk and lower extremities (USC Spine Exercise Program) for persons who have undergone a single-level microdiscectomy for the first time.

Nearly half of the cases scheduled for lumbar microdiscetomy exhibited asymmetry of at least 12.6% in the lumbar multifidus innervated by the L5 nerve root, which is located below the level of the injured disc. A trained radiologist can readily identify this multifidus asymmetry.
