For the ISWT, the patient is required to walk around two cones set 9 metres apart (so the final track is 10 metres) in time to a set of auditory beeps played on a CD. Initially, the walking speed is very slow, but each minute the required walking speed progressively increases. The patient walks for as long as they can until they are either too breathless or can no longer keep up with the beeps, at which time the test ends. The number of shuttles is recorded. Each shuttle represents a distance of ten metres (i.e each time the patient reaches a cone is 1 shuttle). The results of the ISWT can be used to prescribe the intensity of walking training.
