“…Our results triangulate well with the findings from our qualitative analyses [17,33]. DEKA Arm users at all levels thought that the DEKA Arm was beneficial, with the majority of users reporting that they could perform activities using the DEKA Arm that they could not with their existing prostheses [17].…”

“…DEKA Arm users at all levels thought that the DEKA Arm was beneficial, with the majority of users reporting that they could perform activities using the DEKA Arm that they could not with their existing prostheses [17]. Our data suggest that perceived functional benefits, particularly in the area of self-care activities, were somewhat greater for SC users [17]. The findings from the current study suggest that the benefits of increased independence and less difficulty in performance of functional activities may be more highly valued by participants with amputation than speed of fine motor activities (dexterity).…”

“…During the usability study, the VA also performed extensive testing to quantify what activities subjects were able to do with their existing prostheses and what they were able to achieve when using the gen 2 and gen 3 prototypes. Analyses of qualitative study data found that the majority of subjects wanted to receive a DEKA Arm, largely because of the new activities that they could perform using the DEKA Arm [17]. The purposes of this article are to report on quantitative study findings, specifically to (1) quantify outcomes, including dexterity, performance of daily activities, and prosthetic skill and spontaneity of users of the DEKA Arm and (2) compare outcomes scores when using the DEKA Arm with scores using the existing prosthesis.…”

Abstract-Mechanical properties of the DEKA Arm and associated engineering innovations are easy to observe. What is less clear is how these advances translate into functional benefits for the user with amputation. Study aims were to (1) quantify outcomes including dexterity, performance of daily activities, and prosthetic skill and spontaneity of users of the DEKA Arm and (2) compare outcomes when using the DEKA Arm with scores using the existing prosthesis. This was a quasi-experimental study. Descriptive analyses examined outcomes by DEKA Arm configuration level. Of the 39 subjects fit with a DEKA Arm, 32 were trained in use and completed end-of-study testing. Data from 26 prosthetic users were used to compare outcomes using existing prostheses with outcomes with the DEKA Arm. Dexterity and activity performance with the DEKA Arm varied by amputation level (p < 0.01). Self-reported function and number of activities performed using the prosthesis were similar across levels. Comparisons with existing prostheses showed the effect on dexterity varied by level. Activity performance and spontaneity of prosthetic use improved for users of the shoulder configuration level, while use of the prosthesis to perform activities and perceived difficulty performing self-selected tasks improved for all levels.

“…An earlier article resulting from the VA optimization study reported that the majority of study participants viewed the DEKA Arm favorably, could do new activities using the DEKA Arm that they were unable to do with their current prostheses, and wanted to receive a DEKA Arm when it becomes available in the future [3]. That said, most participants also had concerns about using the device at home and made recommendations that they hoped would be incorporated in the optimization of the device [3]. This article describes the qualitative usability feedback from VA subjects and clinicians that was generated during the VA optimization study.…”

Abstract-This article summarizes feedback from Department of Veterans Affairs (VA) subjects and clinicians gathered during the VA optimization study of the DEKA Arm. VA subjects and clinicians tested two DEKA Arm prototypes (second-generation [gen 2] and third-generation [gen 3]). Features of the prototypes in three configurations are described. DEKA used feedback from the VA optimization study and from their own subjects to refine the gen 2 prototype. Thirty-three unique subjects participated in the VA evaluation; 26 participated in the gen 2 evaluation (1 subject participated twice), 13 participated in the gen 3 evaluation, and 5 participated in both gen 2 and gen 3 evaluations. Subject data were gathered through structured and open-ended surveys, interviews, and audio-and videotaped sessions. Study prosthetists and therapists provided ongoing feedback and completed surveys at the end of each subject's protocol. Eleven categories of feedback were identified: weight, cosmesis, hand grips, wrist design, elbow design, end-point control, foot controls, batteries and chargers, visual notifications, tactor, and socket features. Final feedback on the gen 3 was generally positive, particularly regarding improvements in wrist design, visual notifications, foot controls, end-point control, and cosmesis. Additional refinements to make the device lighter in weight, eliminate external wires and cables, and eliminate the external battery may further enhance its perceived usability and acceptability.

Do users want to receive a DEKA Arm and why? Overall findings from the Veterans Affairs Study to optimize the DEKA Arm

Abstract: The majority of amputees in this study expressed a desire to receive the DEKA Arm, a device which provides multiple powered degrees of freedom and is operated predominantly by foot controls. The majority reported functional advantages of the DEKA Arm over their existing prostheses.
