The First Dorsal Interosseous muscle of the hand was studied during at low (10% max) and high (80% max) force contractions, and the shape of individual motor unit action potentials was extracted in both control and neuropathic individuals.
The NeuroMap system is able to identify known abnormalities in motor unit action potential shapes that occur as a result of neurogenic processes.
Importantly, results proved consistent with known clinical history of the patients and needle EMG results.
Needle EMG outcomes are based on data collected at Emory University and Baystate Medical Center clinical sites, and on historical data such as: Nikolic M., Detailed Analysis of Clinical Electromyography Signals EMG Decomposition, Findings and Firing Pattern Analysis in Controls and Patients with Myopathy and Amytrophic Lateral Sclerosis.
