Subscores of the Graded Redefined Assessment of Strength, Sensation and Prehension (GRASSP) test reported at the conclusion of each phase of the study. Improvement (Δ) during stimulation combined with physical therapy (stim + PT) exceeded the minimal detectable difference (MDD) for all subscores of the GRASSP test except fingertip sensation (strength: Δ37 vs. MDD 7; sensation: Δ−2 vs. MDD 4; qualitative prehension: Δ6 vs. MDD 5; and quantitative prehension: Δ11 vs. MDD 6.
