Distribution of strength testing for quadriceps and hamstrings muscles for all subjects tested.

		N	Minimum	Maximum	Mean (SD)
Quadriceps strength right (kg)	All patients	85	0.21	41.40	7.7 (±7.3)
	Male	64	0.21	41.40	8.4 (±8.0)
	Female	21	0.53	13.4	5.4 (±3.9)
Quadriceps strength left (kg)	All patients	85	0.1	39.8	7.3 (±6.8)
	Male	64	0.1	39.8	7.9 (±7.3)
	Female	21	0.25	16.8	5.3 (±4.1)
Percent of predicted quadriceps strength of both legs combined	All patients	81	0.22%	84.9%	18.7 (±15.6)
	Male	60*	0.22%	84.9%	17.9 (±16.0)
	Female	21	1.78%	50.4%	20.9 (±14.6)
Hamstring strength right (kg)	All patients	85	0.1	20.2	9.2 (±4.1)
	Male	64	0.1	20.2	3.0 (±3.1)
	Female	21	0.33	12.1	7.1 (±3.5)
Hamstring strength left (kg)	All patients	84	0.1	20.2	9.0 (±4.1)
	Male	64	0.1	20.2	9.6 (±4.2)
	Female	21	1.3	16.0	7.4 (±3.6)

^*N = 60 because height was not available for 4 subjects so percent predicted could not be calculated.
