Functional & Movement
Disorder Surgical Program

The Functional and Movement Disorder Program (F&MD) at Houston Methodist Neurological Institute focuses on treating patients with conditions, such as Parkinson’s disease, essential tremor, spasticity, chronic pain and some behavioral disorders, including obsessive compulsive disease. Surgical treatment for these conditions primarily involves implanting devices that help control symptoms.

View John Sinclair's patient story about how deep brain stimulation helps treat Parkinson's disease: 

Our program has many firsts in the treatment of functional and movement disorders, including the following:
  • The first in the country to implant the new pulse generator for deep brain stimulation that incorporates a much more sophisticated programming paradigm than previous devices
  • The first in the country to implant a new generation of programmable intrathecal drug delivery devices that utilize a distinctly unique and highly accurate medical distribution mechanism
  • The first in the country to implant a pulse generator for the treatment of pain with a circuit that adjusts output based on posture or body position
  • The first in Texas to implant a new spinal cord stimulation electrode for improved pain control

We offer programs specific to the treatment of movement disorders, functional disorders and chronic pain.

Division for the Treatment of Movement Disorders
Our considerable experience treating movement disorders is evidenced by approximately 1,600 deep brain stimulation procedures that have been performed, primarily to treat Parkinson’s disease and tremors. We have treated over 1,000 patients with implanted drug delivery devices to administer intrathecal baclofen for spasticity.

Division for the Treatment of Functional Disorders
Currently, this division treats select patients with obsessive compulsive disorders. Our goal is to also treat patients with severe depression within the next few years.

Division for the Treatment of Chronic Pain
We have treated more than 3,000 patients for chronic pain using implanted devices that provide neurostimulation of the spinal cord and intrathecally administered medications.

Houston Methodist is committed to our research programs to find new treatment options for our patients. Our research projects in the functional and movement disorder program include a clinical study of a new deep brain stimulator device for treatment of Parkinson’s disease and tremors. We recently completed a study of gene therapy for treatment of Parkinson’s disease using a stereotactic approach for delivery, and plan to participate in more clinical trials in the near future.

Our doctors specialize in managing Parkinson’s disease, essential tremor, spasticity, chronic pain and other movement disorders at Houston Methodist Hospital.
