Efficiency of voluntary opening hand and hook prosthetic devices: 24 years of development?

Gerwin Smit, MSc, et al.

Figure 3. Schematic overview of test setup during first two tests. Cable activation force and displacement are measured. Fact = force activation cable, LVDT = linear variable differential transformer, mVact = voltage force sensor (unamplified), USB = universal serial bus, Vact = voltage force sensor (amplified), VLVDT = voltage displacement sensor, Xact = displacement activation cable.

We mechanically tested nine voluntary opening (VO) upper-limb prostheses, four hooks and five hands. The first goal was to objectively compare the different devices. The second goal was to see whether VO devices had improved during the past two decades. We measured multiple parameters, e.g., pinch forces, cable pull forces, and cable displacements. The outcomes will help the clinician and the patient select the optimal prosthesis. The results showed that the tested hooks performed much better than the hands. The performance of the tested hands was insufficient. No improvements were shown compared with the devices tested in 1987.
