The ability to push oneself up is particularly important for shifting position when seated and for transferring into and out of wheelchairs. Surgeons compared two operations to restore the ability to push up in children. Two years after surgery, scores rating pushing strength for 16 arms that had been operated on had a distribution displayed here with a histogram and boxplot. (Mulcahey, M. J., Lutz, Cheryl, Kozen, Scott, Betz, Randel, "Prospective Evaluation of Biceps to Triceps and Deltoid to Triceps for Elbow Extension in Tetraplegia," Journal of Hand Surgery, 28, 6, 2003)
