Background: Compared to healthy people, patients with chronic lower back pain have reduced balance abilities which may cause proprioception problems, patients with chronic lower back pain avoid physical activities due to pain, and reduced activity levels lead to muscle weakening, which can further exacerbate pain. Recently, there have been many studies on the use of sensory stimulation; and among these studies, interventions that use vibrational stimulation have shown functional improvements in the patients.
Objects: This study examined the effects of a stabilization exercise with vibration stimulation on the balance ability and disability in patients with chronic back pain.
Methods: The subjects of the study were 30 persons who were randomly assigned to the experimental group and the control group, with 15 subjects in each. The subjects were evaluated before and after intervention via a balance ability test, the Korean Oswestry disability index (KODI) test, a pain test, and a proprioceptive sensory test. Both groups received general physical therapy. The experimental group performed the stabilization exercise with vibration stimulation, and the control group performed a general stabilization exercise, three times a week for six weeks.
Results: After the intervention, both groups showed significant improvements in the balance ability test, the KODI test, the pain test, and the proprioceptive sensory test. The experimental group showed statistically significant, higher improvements than the control group in the balance ability test, the KODI test, and the proprioceptive sensory test.
Conclusions: The stabilization exercise with vibration stimulation for patients with chronic back pain has been reported to provide greater functional improvements than the conventional intervention method. Therefore, the stabilization exercise in a vibration stimulation environment could be a useful intervention for patients with chronic back pain.
