Improvement in sagittal alignment and mechanical low-back pain following deep brain stimulation for Parkinson’s disease: illustrative case

BACKGROUND Parkinson’s disease (PD) is a common neurogenerative disease marked by the characteristic triad of bradykinesia, rigidity, and tremor. A significant percentage of patients with PD also demonstrate postural abnormalities (camptocormia) that limit ambulation and accelerate degenerative pathologies of the spine. Although deep brain stimulation (DBS) is a well-established treatment for the motor fluctuations and tremor seen in PD, the efficacy of DBS on postural abnormalities in these patients is less clear. OBSERVATIONS The authors present a patient with a history of PD and prior lumbosacral fusion who underwent bilateral subthalamic nucleus DBS and experienced immediate improvement in sagittal alignment and subjective relief of mechanical low-back pain. LESSONS DBS may improve postural abnormalities seen in PD and potentially delay or reduce the need for spinal deformity surgery.
