Hip ROM required for walking
Stance:
-Flex = 0-30
-Ext = 0-20
Swing:
-Flex = 20-30
Knee ROM required for walking

Stance:
-DF = 0-10
-PF = 0-20
Swing:
-DF = 0-20
ROM required for running
2x ROM for walking
General gait changes for contracture or tightness
-Decreased ROM on opposite side.
-Early gait phases.
General gait changes for weakness
