More Information

Bio Statement

Dr. David Walk is a neurologist at the University of Minnesota Medical Center Fairview with a subspecialty interest in neuromuscular diseases. Dr. Walk currently directs the University of Minnesota's multidisciplinary ALS and Charcot-Marie-Tooth clinics. Named a "top doctor" by Minneapolis St. Paul Magazine, he believes that the management of neuromuscular disorders requires a team dedicated to providing comprehensive care.

Dr. Walk has been an Associate Professor of Neurology at the University of Minnesota Medical School since 2005 and a staff neurologist at the University of Minnesota Medical Center, Fairview since 1999; he is also the Medical Director of the electromyography laboratory.

Research Interests

Dr. Walk's research interests include ALS and other motor neuron disorders, Charcot-Marie-Tooth disease, and quantitative sensory testing in patients with neuropathic pain.

Research Projects

Dr. Walk's ongoing research projects are focused on ALS as well as sensory evaluation in neuropathy and neuropathic pain. He was the Principal Investigator of a study entitled “Quantitative Sensory Testing in Pathologic Pain States” sponsored by the Minnesota Medical Foundation and the local Principal Investigator of a study sponsored by the University of Minnesota Clinical and Translational Science Institute involving chemotherapy-induced peripheral neuropathy. Ongoing research projects in the neuromuscular section include a longitudinal study of imaging biomarkers in ALS, a prospective evaluation of quantitative sensory testing in pathologic pain, and the assessment of A-delta and C-fiber small nerve function in established chemotherapy-associated neuropathy.
