Static foot angle

Static foot angle (SFA):
• based on Fiess line
• angle formed between two lines – one from centre of medial malleolus to navicular tuberosity and from the navicular tuberosity to the centre of the medial aspect of the first metatarsal head
• several studies have shown the mean angle to be about 140 degrees and is predictive of dynamic function (McPoil, unpublished).
• angle has been shown to be lower in those with a history of medial tibial stress syndrome
