Preface: "The aim of this test is to walk as far as possible in six minutes. You will walk back and forth in the hallway. Six minutes is a long time to walk, so you will be exerting yourself. You may get out of breath or become tired. You are allowed to slow down, to stop, and to rest as necessary. You may stand and rest, but resume walking as soon as you are able. Are you ready to do that?"

Instructions: Walk around the object at each end. I am going to use this counter to keep track of the distance you cover. Remember the aim is to walk as far as possible, but do not run or jog. Start now or when you are ready."

Measurements: Total distance, average speed, and fatigability are automatically calculated based on your input.

Encouragement: “You're doing a good job and you have 5 minutes left," or “Keep up the good work. You have 4 minutes to go” is given after each minute of the test; no other communication should occur during the test.
