nd: no data; : paretic; np: nonparetic; : passive extensibility of Gastrosoleus complex (V1, slowest stretch velocity possible); : angle of catch of Gastrosoleus complex (V3, fastest stretch velocity possible), : : spasticity angle; : grade of spasticity; : tension threshold during a slow passive stretch of the Gastrosoleus complex. PSC: Passive Stretch Course; age in years; values of , , , , and PSC are expressed in degrees, measured from 0° being the position of minimal stretch of the gastrosoleus complex.
