Effects of Association of Trunk Stretching and Segmental Stabilization Exercises in Chronic Unspecific Low Back Pain

"Both groups will perform segmental stabilization exercises (SS), which emphasis is for the lumbar multifidus muscles (ML) and transversus abdominis (TAR), using protocol proposed by Richardson et al. Four types of exercises will be carried out with four sets of ten exercises. Muscle contractions will be held for ten seconds and followed by ten seconds rest. Between each type of exercise patients will rest for one-minute interval.~Patients of segmental stabilization active stretching group (SSASG) will perform stretch exercises in four sets of 30 seconds for each muscle. The active stretching exercises will last 15 minutes. The muscles that will be stretched are pectorals, latissimus dorsi, latissimus dorsi, teres major, rectus abdominis, external and internal oblique."

Between each type of exercise patients will rest for one-minute interval.~Patients of segmental stabilization placebo stretching group (SSPSG) will perform exercises that simulate stretching, but the muscles will not suffer effective stretch. The placebo stretching exercises will last 15 minutes. The muscles that will be stretched are wrist flexors and extensors muscles and fingers flexors and extensors muscles."
