Orthotic and prosthetic devices having integrated features such as cushioning features are described, as well as methods for computer aided designing and making of these devices. The orthotic or prosthetic devices comprise a cushioning layer superimposed onto an orthotic or prosthetic shell, the cushioning layer comprising an array (35) of discrete solid and resilient cushioning elements (31). In one preferred embodiment, said cushioning structure is a beam, defined around a centerline of any arbitrary shape. In another preferred embodiment, said cushioning structure has the shape of a spiral.

A prosthetic hand system may include a plurality of prosthetic fingers and a prosthetic thumb. The prosthetic hand system may include a thumb drive mechanism that may be used to actuate the prosthetic thumb. In some examples, the thumb drive mechanism may be configured to enable the prosthetic thumb to perform a pinching or grasping motion and a release motion. The prosthetic hand system may also include a backlock that enables the prosthetic thumb to maintain pinching or gripping pressure after a motor has been disengaged. The prosthetic hand system may also include a gear lock that may be configured to lock a finger joint. The prosthetic hand system may also include an adaptive gripping joint that may be located on each prosthetic finger. In some examples, the adaptive gripping joint may be configured to passively adapt the plurality of prosthetic fingers to one or more differently shaped objects.
