A method of measuring a range of movement of a joint of a patient including the steps of: capturing an image including at least part of the patient; processing measurement points positioned on the image; determining a measurement axis that connects the measurement points; determining a reference axis; and measuring an angle at an intersection of the measurement axis and the reference axis according to the range of movement of the joint of the patient. The invention also resides in a method of measuring a distance or displacement in an image including the steps of: providing a scale for the image; capturing the image including at least part of a patient and the scale; positioning a marker on the image that defines a distance to be measured; and measuring the distance using the marker and the scale.
