The DEKA Arm has multiple degrees of freedom which historically have been operated primarily by inertial measurement units (IMUs). However, the IMUs are not appropriate for all potential users; new control methods are needed. The purposes of this study were: 1) to describe usability and satisfaction of two controls methods—IMU and myoelectric pattern recognition (EMG-PR) controls—and 2) to compare ratings by control and amputation level. A total of 36 subjects with transradial (TR) or transhumer...

For people with digit amputations, prosthetic choices have been limited to cosmetic restorations usually made of silicone, opposition posts, or mechanical linkages. In a study in Australia, those with partial hand losses perceive themselves to be at a higher disability than those with unilateral transradial or transhumeral upper extremity amputations. 1 More than half of partial hand amputees are unable to return to their previous work. 2 Of those that did return to work, the majority did not fi...

ABSTRACTLower limb amputees have less efficient gait patterns that may in part be due to spatiotemporal asymmetries. Transfemoral (TF) amputees are believed to have greater gait asymmetries than transtibial (TT) amputees, but this has not been clearly established. The purpose of this study was to de

We studied the pressure patterns in the residual limbs of transradial amputees during their voluntary commands for finger taps. Topographic maps of pressures exerted against the hard prosthetic socket were registered with an array of 32 pressure sensors, to produce residual kinetic images (RKIs) of the limb. Results with 2 untrained subjects demonstrated that RKIs are reliable decoders of efferent commands. Coupled with a trained filter, RKIs can provide biomimetic control over multiple degrees ...

ABSTRACT To initiate a database on material properties of typical laminations used in prosthetic limb sockets, the authors subjected samples of common prosthetic laminations to tensile and bending tests. Eight varieties of lay-up materials (fibers) were each laminated separately with one of three common resins (matrix), resulting in 24 combinations of fiber/resin laminates. In addition to composition, the bending responses of various carbon fiber laminations were measured to evaluate the role of...

Many upper-limb amputees retain the ability to control a hand, however no suitable mechanical hand is available to them. A hand/arm virtual interface (VIA) developed at Rutgers allows amputees to manipulate objects within a virtual environment. The interface uses residual myo-kinetic signals expressed at the surface of the forearm to control the virtual hand, while arm reaching is transduced by a goniometer. In preliminary tests amputees readily gained control of the virtual hand, and successful...

Imagined phantom movements have real physiologic expressions within the residual limb, which we termed residual kinetic activity. In order to exploit the residual functions of transradial amputees we developed a system to register dynamic pressure patterns produced by the residual limb during voluntary commands for motions. This pattern was then converted to a multidimensional vector. Specific requested finger motions were thus detected from the forearm as residual kinetic vectors (RKVs). To dec...
