The research team of Sasha N. Zill, Ph.D., and Sumaiya Chaudhry, in collaboration with Chris J. Dallmann, Ph.D., and Josef Schmitz, Ph.D, at Bielefeld University and Ansgar Büschges, Ph.D., at the University of Cologne, applied forces and joint torques to the legs of stick insects to determine their impact on muscle activation. Their findings were published in the Journal of Neurophysiology.

"Current prosthetic devices for leg amputees incorporate sensors and microprocessors to regulate joint stiffness. The new findings suggest mechanisms for making these joints more adaptable, permitting more natural leg movements," said Zill, senior author and professor of anatomy in the department of biomedical sciences at the Joan C. Edwards School of Medicine.
