STUDY DESIGN: Randomized controlled trial. OBJECTIVE: To compare changes in self-rated disability, pain, and anticipatory postural adjustments between specific trunk or general exercise in patients with chronic low back pain. SUMMARY OF BACKGROUND DATA: Chronic low back pain is associated with altered motor control of the trunk muscles. The best exercise to address altered motor control is unclear. METHODS: Sixty-four patients with chronic low back pain were randomly assigned to a specific trunk exercise group (SEG) that included skilled cognitive activation of the trunk muscles in addition to a number of other best practice exercises, while the general exercise group (GEG) only performed seated cycling exercise. The training program was 8-weeks. Self-rated disability and pain scores were collected before and after the training period. Electromyographic (EMG) activity of various trunk muscles was recorded during performance of a rapid shoulder flexion task before and after training. Muscle onsets were calculated, and the latency time (ms) between the onset of each trunk muscle and the anterior deltoid formed the basis of the motor control analysis. RESULTS: Following training, disability was significantly lower in the SEG (d = 0.62, p = 0.018). Pain was reduced in both groups following training (p < 0.05), but was lower for the SEG (p < 0.05). Despite the GEG performing no specific trunk exercise, similar changes in trunk muscle onsets were observed in both groups following training. CONCLUSION: Specific trunk exercise elicited greater reductions in self-rated disability and pain, while similar between group changes in trunk muscle onsets were observed. The motor control adaptation appears to reflect a strategy of improved coordination between the trunk muscles with the unilateral shoulder movement. Trunk muscle onsets during rapid limb movement do not appear a valid mechanism of action for specific trunk exercise rehabilitation programs.
