Article

The purpose of this article is to describe the two DEKA Arm prototypes (Gen 2 and Gen
3) used in the Veterans Affairs Study to optimize the DEKA Arm. TECHNIQUE: This
article reports on the features and functionality of the Gen 2 and Gen 3
prototypes discussing weight, cosmesis, grips, powered movements Endpoint,
prosthetic controls, prosthetist interface, power sources, user notifications,
troubleshooting, and specialized socket features; pointing out changes made
during the optimization efforts. DISCUSSION: The DEKA Arm is available in three
configurations: radial configuration, humeral configuration, and shoulder
configuration. All configurations have six preprogrammed grip patterns and four
wrist movements. The humeral configuration has four powered elbow movements. The
shoulder configuration uses Endpoint Control to perform simultaneous multi-joint
movements. Three versions of foot controls were used as inputs. The Gen 3
incorporated major design changes, including a compound wrist that combined
radial deviation with wrist flexion and ulnar deviation with wrist extension, an
internal battery for the humeral configuration and shoulder configuration, and
embedded wrist display. CLINICAL RELEVANCE: The DEKA Arm is an advanced upper
limb prosthesis, not yet available for commercial use. It has functionality that
surpasses currently available technology. This manuscript describes the features
and functionality of two prototypes of the DEKA Arm, the Gen 2 and the Gen 3.
