Brief summary
The purpose of this randomized clinical trial of low back pain exercise programs is to determine if trunk control can be changed by core stabilization exercises. The proposed mechanism of pain reduction and functional improvement of core stabilization exercises is that it enhances trunk movement and muscle control. This study will provide preliminary evidence of the link between patient outcomes and treatment mechanisms. The investigators hypothesize that: * both treatment groups will demonstrate significant improvements in pain and function; * only subjects in the core stabilization group will demonstrate significant improvements in trunk movement and muscle control.
Interventions
OTHERCore Stabilization
3 Stages: Stage 1: emphasis on neutral spine position, co-contraction of stabilizing muscles with performance feedback through observation and palpation for correct muscle activation; patient education Stage 2: promotes maintenance of co-contraction while performing movements of the arms/legs and trunk progressing to preformance of these exercises on unstable surfaces; trunk muscle conditioning also emphasized; feedback gradually reduced. Stage 3: emphasis on maintenance of co-contraction while performing functional activities; stable and unstable surfaces; use of perturbation and random practice to enhance motor learning.
OTHERTrunk Motion and Fitness
3 Stages: Stage 1: reducing pain and restoring spine motion and flexibility; patient education Stage 2: trunk muscle conditioning exercises Stage 3: trunk muscle conditioning and cardiovascular conditioning exercises
