2.2. Outcome Measures
ulcer
SECONDARY, ULCER
The outcome measures were assessed at three points during the timeline: at baseline, a four-week exercise training period, and a twelve-week period. The primary outcome measure was ulcer surface area. The secondary outcome measure was ulcer volume (UV) measurement in cmPrimary outcome measures: The ulcer surface was measured by covering the ulcer with a piece of sterilized transparency film and using a fine-tipped transparency marker to trace the ulcer perimeter on the film. For each ulcer, a different transparency was employed. After that, the tracing was applied to metric graph paper, and the number of 1 mm that it contains was counted (only squares that were exactly 1 mm in size were counted inside the perimeter, and the area was transformed to square centimeters) [Secondary outcome measures: ulcer volume measurement in cmThe ulcer was drawn on clear paper and placed over metric graph paper so that it would have the greatest length and width. Then, a disposable measuring tape was inserted into the ulcer’s bottom part to record the depth of the ulcer [
