Sizing chart for Cyborg Beast prosthetic hand. Instructions: locate the child’s age in the bottom (X axis) and follow the line to the regression curve and then locate the intercepting line corresponding to the scale % on the left side (Y axis). Example: For a 5-year-old, the scale % of the Cyborg Beast would be 118% (±1.44%). This cubic regression equation was derived from a mixed sample of 11 children with ages ranging from 3 to 16 years of age.
