A parametric 3D printed assistive device for people with cerebral palsy – assessment of outcomes and comparison with a commercial counterpart

Figures & data

Figure 1. Schematic description of the stages of the study.

Figure 2. The 3D model of the configurable AD (ConfAD) and the measurement instructions. The cuff can be opened and closed to fix the handle to the hand using a hook located on the ulnar side.

Table 1. The IPPA/QUEST scores for the participants. CP – Cerebral palsy, NPCA – Non-progressive congenital ataxia. ConfAD – 3D printed configurable assistive device, CommAD – Commercial assistive device.
