Muscular activity means value and standard deviations. The value reported for each muscle corresponds to the percentage of stride in which the muscle is active. The muscles explored were Right and Left Erector Spinae (RES, LES), Gluteus Maximum (G MAX), Gluteus Medius (GME), Rectus Femoris (RF), Lateral Hamstrings (LH), Lateral Gastrocnemius (GAS) and Tibialis Anterior (TA). Light grey bars correspond to patients, dark grey bars to controls. Self-selected speed (a) and high speed (b) values are reported. A significant difference was found for RF ((p < 0.02) and TA (p < 0.008) when compared within the patients group at different speed.
