“…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].…”

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.

“…This prosthesis has eight powered DoFs and one passive DoF which are needed for the movements in prosthetic finger phalanges in ring and little finger where have been slaved with middle finger . Prosthetic fingers of this device are capable for providing six distinct types of grasping patterns for the amputee which are operated by linkage mechanisms along with DC motor actuation . This device uses active two revolute (2R) wrist units which allows only two wrist movements: supination‐pronation and flexion‐extension.…”

“…The uGrip II hand is a high functional and lightweight device for amputees which is low cost compared with other conventional prosthetic devices . In DEKA RC gen 3 arm, clinical feedback was taken from 13 unique participants into 11 key categories for identifying areas for continued improvements . The weight was one of the key issues during the arm extension for the transhumeral amputees who has long residual limb .…”

Background Prosthesis is a wearable device that intends to provide the functionality and/or appearance of a missing body part. In the case of trans‐radial prostheses, the wearer or the trans‐radial amputee is fitted with an artificial wrist and a hand that is either mechanically or electro‐mechanically operated. Main aim is to enable the wearer to perform activities of daily living with minimal external assistance. Methods In this review paper, hardware systems of state‐of‐the‐art trans‐radial prostheses have been briefly discussed. Focus is to provide an insight on the latest technologies employed in development of its mechanical systems: terminal devices, artificial wrist joints, and body attachments. In that context, latest hardware designs on terminal devices for grasping motion are presented as it is the primary function of trans‐radial prostheses. Hardware designs of prosthetic wrists and body attachments are also reviewed. Finally, latest trends and future directions on design of trans‐radial prostheses are explored and presented. Conclusions Size, shape, weight, durability, appearance, and functionality are the key factors that need to be considered when developing a trans‐radial prosthesis. Moreover, the current developments are moving closer to a human upper limb. However, the availability of these devices is minimum due to high‐tech involved and the high cost, which necessitates further development trans‐radial prostheses.

“…A synopsis of the general training protocol used in the Optimization Study was presented in two articles [12][13]. Another article describing the virtual reality environment (VRE) portion of the training protocol for the DEKA Arm second generation prototype (Gen 2) reported that VRE training was particularly valuable for people with upper-limb amputation who must master a large number of controls and for those who need a structured learning environment [14].…”
