Relaxation Techniques in Low Back Pain Patients: A Randomized Controlled Trial

Low back pain (LBP) is a common problem, affecting 11% of the population in Greece. Pain can last upwards of 6 wk and impact functional ability and quality of life. Treating LBP often includes the use of alternative methods, such as relaxation techniques. We tested whether relaxation techniques could reduce stress and pain and improve quality of life. Patients engaged in methods such as diaphragmatic breathing, progressive muscular relaxation, autogenic training, and guided imagery. The treatment group consisted of 31 randomized patients and the control group had 33. The treatment group followed an 8-wk relaxation program with weekly sessions and practiced techniques every day by listening to a compact disk at home (2×/d). The control group did not follow relaxation techniques. No statistically significant differences were present regarding the Perceived Stress Scale, body-mass index, and satisfaction with functional ability. However, statistically significant differences were found in the Brief Pain Inventory score and multidimensional locus of control. We also found decreases in all three cortisol measurements for the treatment group. Relaxation techniques provide positive results in pain reduction and cortisol decrease and must therefore be incorporated into rehabilitation protocols.
