The Anatomy Lesson of Dr. Tulp

by Rembrandt 1632

Our Hand Research Laboratory performs orthopaedic biomechanics and rehabilitation research of the hand and upper extremity. Currently, our research activities focus on biomechanics and sensorimotor function with a clinical focus on carpal tunnel syndrome and hand/wrist arthritis. Our work related to carpal tunnel mechanics involves studying the material and mechanical properties of the transverse carpal ligament, investigating the structural properties of the carpal tunnel, and developing computational models. Related to sensorimotor function, we have been examining the neuromuscular dysfunction of the hand. We study joint mechanics and pathomechanics as they related to arthritic conditions at the trapeziometacarpal and intercarpal joints. Our research involves cutting edge bioengineering technology including motion analysis, ultrasound imaging, computer tomography, magnetic resonance imaging, electromyography, robotics, and computational modeling.
