A simulation-based study for optimizing proportional-integral-derivative controller gains for different control strategies of an active upper extremity model using experimental data.

A unique study imaging brain activity in children born with upper limb difference—for example, one hand—has shown the amazing ability of the brain to adapt to compensate and support their daily lives.

Limb formation is currently explained by a long-standing model, which states that signals from tissue in the limb bud called the apical ectodermal ridge (AER) instruct cells of the upper arm to form ...
