Michelle Kvalsund and Lusaka Team

Clinical neuromuscular expertise, patients and geographical region
Dr. Michelle Kvalsund is the director of the UTH EMG clinic, and is a U.S. trained neurologist with expertise in neurophysiology and neuromuscular disease, with an emphasis on peripheral neuropathies.   UTH is a tertiary referral center, and patients with neuromuscular disease are referred from across the country.  The neuromuscular clinic currently follows approximately 300 patients with neuromuscular disease.

Lusaka Teaching Hospital Clinical Ward

Genetics and preclinical science expertise and facilities
The Neurology Research Office at the University Teaching Hospital of Zambia was established by Dr. Birbeck and has been continuously funded for more than 15 years.  Genetic research programs have predominantly focused on pathogen genetics and genetics of host response, with additional research expertise in neuroimmunology, neuroepidemiology, and clinical trial design.

How the new international centre will benefit our research and clinical programmes
Despite a large population of patients with neuromuscular disease, genetic testing is not currently available in Zambia, and patients with neuromuscular disease represent a particularly underserved population.  As part of this study, we look forward to building capacity in Zambia for the diagnosis, evaluation, and treatment of patients with neuromuscular disorders.
