Dr. Amundsen-Huffmaster’s research interests include applying engineering principles to analyze human movement (biomechanics) and investigate how the cardinal motor symptoms of Parkinson’s disease progress and respond to treatments such as deep brain stimulation (DBS). She is particularly interested the pathophysiology of freezing of gait. To investigate our hypotheses, the Movement Disorders Lab uses techniques to quantitatively measure movement, including motion capture, force plates, wearable sensors, electromyography (EMG), electroencephalography (EEG), and DBS recordings of local field potentials (LFPs). We also use a combination invasive and non-invasive neuromodulation, such as DBS, transcranial direct current stimulation (tCDS), and electrical vestibular stimulation (EVS) to probe the neural system and measure changes in neural and motor (behavioral) activity.
