“…In the past two decades, many new materials have become available that can be used for mechanism, bearings, gloves, etc. Meanwhile, various user studies clearly mapped the needs of the prosthesis user [4,17]. However, comparisons between our results and Corin et al's results showed no significant difference for the required work or pinch forces for the hooks or for the hands (Figure 8(a) and 8(b)).…”

Abstract-Quantitative data on the mechanical performance of upper-limb prostheses are very important in prostheses development and selection. The primary goal of this study was to objectively evaluate the mechanical performance of adultsize voluntary opening (VO) prosthetic terminal devices and select the best tested device. A second goal was to see whether VO devices have improved in the last two decades. Nine devices (four hooks and five hands) were quantitatively tested (Hosmer model 5XA hook, Hosmer Sierra 2 Load VO hook, RSL Steeper Carbon Gripper, Otto Bock model 10A60 hook, Becker Imperial hand, Hosmer Sierra VO hand, Hosmer Soft VO hand, RSL Steeper VO hand, Otto Bock VO hand). We measured the pinch forces, activation forces, cable displacements, mass, and opening span and calculated the work and hysteresis. We compared the results with data from 1987. Hooks required lower activation forces and delivered higher pinch forces than hands. The activation forces of several devices were very high. The pinch forces of all tested hands were too low. The Hosmer model 5XA hook with three bands was the best tested hook. The Hosmer Sierra VO hand was the best tested hand. We found no improvements in VO devices compared with the data from 1987.

“…A BP prosthetic hand requires up to 2,292 Nmm of energy to pinch 15 N, a user effort that is uncomfortably high [8]. User needs of people with hand amputation include a higher pinch force [9], a lower activation effort [8], and a lower hand mass [10]. To achieve these goals, an efficient energy transmission is required.…”

Abstract-The goal of this study was to find an efficient method of energy transmission for application in an anthropomorphic underactuated body-powered (BP) prosthetic hand. A pulley-cable finger and a hydraulic cylinder finger were designed and tested to compare the pulley-cable transmission principle with the hydraulic cylinder transmission principle. Both fingers had identical dimensions and a low mass. The only thing that differed between the fingers was the transmission principle. The input energy was measured for a number of tasks. The pulley-cable finger required more input energy than the hydraulic cylinder finger to perform the tasks. This was especially the case in tasks that required high pinch forces. The hydraulic cylinder transmission is therefore the more efficient transmission for application in BP prosthetic fingers.

“…However, obtaining full representation of shapes compatible with anthropometric data of a patient requires using additional technologies. In case of the cosmetic prostheses not only the comfortable fitting, but also the visual aspect is important for the patient [1]. In case of patients having one of the limbs, a mirror image of this limb can be used for making the prosthesis.…”

This paper describes prototyping of an individualized cosmetic arm prosthesis. Aim of the studies was to obtain an anatomically correct, lightweight prosthesis. It was accomplished using additive manufacturing technology of fused deposition modeling. The data was obtained by 3D scanning. An experimental concept of dual extrusion of two different materials was applied -the prosthesis was divided into an elastic shell and a rigid core, manufactured in one process. Obtained results were positive.

Consumer design priorities for upper limb prosthetics

Abstract: Design priorities reflect consumer goals for prosthesis use and vary depending on the type of prosthesis used and age. Future design efforts should focus on the development of more light-weight, comfortable prostheses.
