Fig. 4From: Development and validation of the coffee task: a novel functional assessment for prosthetic grip selection(A) Comparison of completion time for the Continuous Coffee Task between trials completed with the prosthetic emulator emulatator and those completed with intact hands were quantified as a measure of known-group validity. (B) Correlations between the outcomes of the Continuous and Segmented Coffee Tasks vs. outcomes of BBT were quantified as a measure of convergent validityBack to article page
