Results of the grip force test.

Notes: (A) Average maximum grip force (in psi) and associated standard deviation measured before (left open circle and left black circle) and after (right open circle and right black circle) the piano training with the dominant (black filled circles) and nondominant (open circles) hands, respectively, for the participants in the CP group. (B) The same as (A) but for the GRMCD group. (C) Difference (mean grip force after the piano training – mean grip force before the training) as a function of the grip force measured in the first experimental session. Data are presented for all hands tested.

Abbreviations: CP, cerebral palsy; GRMCD, global retardation and movement coordination disorder.
