Results of the prosthesis task.

Mean (and standard error of the mean in brackets) of the normalized maximum hand opening (MHO) (0–1; 0 being closed and 1 being fully opened), as well as of the standard deviation of the normalized maximum hand opening (SD-MHO), and of the duration of the plateau phase (s) for the small and the medium cylinder for both groups on the pretest and the posttest.
