Leg member 6 is connected to base member 4 about an axis of rotation, the leg member preferably comprising shin support portion 18 and side arm portions 20. A means is provided for measuring the angle between base member 4 and leg member 6. A means 12 for communicating the measured angle to the user is also provided. There may be a sensor (22, Fig. 4) located in the heel portion of base member 4 for detecting a users heel and for detecting when it leaves base member 4, prompting the communication means to display the measured angle. There is preferably a talus fixing strap 8 to ensure a more accurate measurement of dorsiflexion angle.
