Evaluating the Features of an Ambulatory Device

Criteria used to evaluate an ambulatory device:

(1) stability of gait (risk of unsteadiness and/or falls)

(2) mobility

(3) distribution of weight

(4) pressure on nerves and/or blood vessels

(5) proper fitting to reduce skin abrasion or other problems

(6) level of exertion involved in use

(7) training and understanding of use

(8) overall cost

total score =

= SUM(points for all 8 parameters)

Interpretation:

• minimum score: 0

• maximum score: 32

• The higher the score the better the device is overall.

• The presence of any poor response would make the device undesirable.
