Regensteiner et al developed a questionnaire for evaluating walking impairment in patients with peripheral arterial disease (PAD). This can be used to identify patients with significant impairment and to monitor effectiveness of therapeutic interventions. The authors are from the Universities of Colorado and Rochester.
Parameters:
(1) difficulty walking a distance during the past month
(2) difficulty walking at a certain speed during the past month
(3) symptoms associated with walking impairment

walking distance score =
= (20 * (points for walking indoors)) + (50 * (points for walking 50 feet)) + (150 * (points for walking 150 feet)) + (300 * (points for walking 300 feet)) + (600 * (points for walking 600 feet)) + (900 * (points for walking 900 feet)) + (1500 * (points for walking 1500 feet))
where:
• Each distance is walked is used as a weighting factor for the points from the degree of difficulty.
fraction of maximal walking distance score =
= (walking distance score) / 6060

where:
• A total symptom score was not calculated. This was because the questions "were not a ranked series."
• The data was presented as "a percentage of the maximal score possible of 4.0."
Interpretation:
• minimum walking distance score: 0
• maximum walking distance score: 34.5
• minimum walking speed score: 0
• maximum walking speed score: 6,060
• The score can be used to compare impairment before and after vascular surgery.
Performance:
• Changes in questionnaire scores correlated with some measurements of treadmill performance.
• Retesting in an untreated control group showed similar scores after 12 weeks.
