Research Interests:
My research interests include the mechanosensitivity of the nervous system during limb movement and function through the use of neurodynamic testing. This includes examination of the biomechanical properties of the nervous system through ultrasound imaging and physiological responses to peripheral nerve movement through electromyographic, symptomatic and range of motion examinations. In particular, I am interested in the effects of nerve injury on nerve mobility, sensitivity and limb function. Recent studies have included the impact of peripheral neuropathy and Type 2 Diabetes Mellitus on lower extremity mechanosensitivity. My current research focuses on the alterations in muscle tone, symptom reproduction and limitations in mobility produced by specific limb movements in the upper and lower extremity in an effort to establish the response of the healthy and injured nervous system to movement.
