Angle and base of gait:
Reference position for a number of measurements and observations of the lower limb, as well as a repeatable postion for foot x-rays.
• patient is asked to walk on the spot for a few steps, then stop so standing in a relaxed position
• the angle of gait is the angle formed by the longitudinal bisections of both feet in the transverse plane (normal assumed to be about 5-10 degrees externally rotated – usually higher if obese)
• the distance between the heels is the base of gait (normally assumed to be around 5cm)
