Methods |
Quasi‐randomised controlled trial.
Within‐subject, cross‐over design. |
Participants |
Group 1: 3 men with unilateral transtibial traumatic amputation, mean age 39 years (SD 10), mean time since amputation 22 years (SD 14).
Group 2: 3 men with unilateral transtibial vascular amputation, mean age 64 years (SD 5), mean time since amputation 5 years (SD 3). A test prosthesis was fabricated for each subject.
Exclusion: residual limb pain, swelling or pressure sores, major gait deviations
Country: USA |
Interventions |
1. SACH‐foot
2. SAFE II
3. Seattle Lightfoot
4. Quantum
5. Carbon Copy II
6. Flex‐Walk
Retroreflective markers were placed at anatomical landmarks. Surface electrodes were placed at rectus femoris, vastus lateralis, medial and lateral hamstring, bilaterally. Subjects walked at self‐selected speed using a treadmill. |
Outcomes |
1. walking velocity
2. cadence
3. stride length
4. single‐limb stance times
5. energy cost (ml oxygen/kg/meter)
6. joint motion |
Notes |
Each foot was worn on the test prosthesis for three weeks. |
