Calculation Formula

FFI = (Ankle Range of Motion / 180) * (Arch Height / 20) * (Foot Pressure / 1000)

Where:
Ankle Range of Motion: Degrees of movement of the ankle joint.
Arch Height: Height of the foot arch in millimeters.
Foot Pressure: Pressure applied to the foot in kilopascals.

Understanding the Formula

The Foot Function Index (FFI) is calculated using the following formula:

FFI = (Ankle Range of Motion / 180) * (Arch Height / 20) * (Foot Pressure / 1000)

This formula takes into account the range of motion of the ankle, the height of the foot arch, and the pressure applied to the foot to provide a comprehensive assessment of foot function.
