This study aimed to compare the effects of horizontal vibration exercise and core exercise on patients with non-specific chronic low back pain. This was an experimental single- blinded, randomized controlled trial. Thirty-nine older patients with non-specific chronic low back pain from the Rehabilitation Center in an University Hospital were randomly assigned to either a horizontal vibration group or a core exercise group. All patients underwent 30 min of each exercise three times a week for 12 weeks. Main outcome measures of perceived pain level, pain-related dysfunction, muscle strength and thickness, and postural stability were assessed at baseline, interim (6 weeks), soon after intervention (12 weeks), and post-intervention of 1 month (follow-up). Both groups showed improved perceived pain level, pain-related dysfunction, muscle strength of lumbar flexion and extension, and balance stability after the intervention(all p<.01). These effects maintained at follow-up of 1 month. There was no significant difference between two intervention groups for any outcome measure. Horizontal vibration and core exercises had the same effects on all outcome measures on patients with non-specific chronic low back pain. Patients with severe back pain and limited active movements may benefit from horizontal vibration equally to core exercise.
