Effect of deep brain subthalamic stimulation on camptocormia and postural abnormalities in idiopathic Parkinson's disease.

Camptocormia has been described in patients with idiopathic Parkinson's disease (PD). We present a patient with young-onset PD in whom the disease progressed over 25 years to a crippling state with severe camptocormia and bent knees. The camptocormia along with other parkinsonian symptoms improved dramatically after bilateral subthalamic deep brain stimulation.
