Biceps strength: impaired MVC/non-impaired MVC; Incidence (%) was defined as the number of trials with spontaneous discharge divided by the total of 12 trials (3 trials each for 4 force levels, MAS: modified Ashworth scale; y/o: year of age; m: meter, Kg: kilogram, mo: month, MVC: maximal voluntary contraction, SD: standard deviation.)
