Influence of an Exercise for Trunk Stabilization Performed in Stable and Unstable Surfaces for Chronic Low Back Pain.

Influence of an Exercise Program for Trunk Stabilization Performed in Stable and Unstable Surfaces for Chronic Low Back Pain: Single-blind, Randomized Controlled Clinical Trial.

Motor control exercises have demonstrated a good option for recovery from chronic low back pain. The purpose of this study is investigated the effectiveness of an exercise program for trunk stabilization performed in stable and unstable surfaces for people with nonspecific chronic low back pain (NCLBP). Patients will be randomly divided into 3 groups; control group will receive placebo treatment with shortwave; stable group will receive an exercise protocol to stabilize the trunk on a stable surface and unstable group will receive the same exercise protocol but performed on an unstable surface.

We hypothesized the unstable group will present pain reduction and functional improvement.

Inclusion Criteria:

• Non-specific low back pain
• Sedentary
• Previous low back pain last 6 months

Exclusion Criteria:

• Traumatic, inflammatory, infectious or tumours etiology
• Positive neurological findings (leg pain)
• Pregnancy
• Previous spine or lower limb surgery
• Contraindicated for short-waves aplication
