A guide-wire could also be set up to guide the runner along the track. Those runners which a greater level of blindness may need the assistance of a sighted running partner, giving verbal directions and attached with a short tether rope or by grasping the partner's elbow. The audio track may be modified to include more cues to when the turning point is approaching, or this can be done verbally by the assistants. Those with limited impairment may be able to run unassisted, but with extra helpers located at either end of the 20m track, and along the side, for safety and to verbally guide the runners if necessary. In addition, there are modifications that may be implemented to suit vision-impaired participants, depending on the severity of the vision impairment. The time between the beeps reduces approximately every minute, and the participants continue until they are unable to keep up. In general, participants run up and back along a 20 meter track in time to audio signals (beeps). Procedure: see the standard beep test description. Measure out the course and place marker cones. Prepare forms and record basic information such as age, height, body weight, gender, test conditions. Perform screening of health risks and obtain informed consent. Pre-test: Explain the test procedures to the subject. Equipment required: at least 20m space clear of obstacles, markerĬones, measuring tape, beep test audio, audio player.
