Treatment of subacute low back pain with a novel device for continuous passive motion of the spine: a report of three cases.

Patients experiencing subacute low back pain (LBP) represent a challenge for the physical therapist. There have been few studies on the use of continuous passive motion of the lumbar spine for the treatment of LBP. Three patients with symptoms of subacute LBP without radiculopathy were treated using a novel device for continuous passive motion of the lumbar spine. The protocol consisted of 12 sessions of lumbar continuous passive motion at 30 minutes per session two to three times per week for 4 to 5 weeks. Outcomes were assessed at baseline and after 12 sessions at 4 to 5 weeks by Oswestry score and active range of motion measurements by a blinded investigator. Clinically significant improvements in Oswestry score and consistent improvements in range were observed. A supervised protocol using a commercial device can benefit some patients with subacute LBP if supervised by a knowledgeable practitioner.
