| Methods |
Quasi‐randomised controlled trial.
Within‐subject, cross‐over design. |
| Participants |
5 active men with unilateral traumatic transfemoral amputation, mean age 37 years (SD 5.1), mean time since amputation 10 years (SD 3.5), participants could walk continuously for at least 5 minutes across a functional range of speeds.
Country: USA |
| Interventions |
1. SACH‐foot
2. Flex‐foot
Participants walked continually around a 50 meter walkway at five walking speeds (40.2, 56.6, 67.1, 80.5, 93.9m/min). A video camera recorded four strides of each participant's walking. |
| Outcomes |
1. relative exercise intensity (percent of age‐predicted maximum heart rate)
2. energy cost (ml oxygen/kg/min)
3. gait efficiency (ml oxygen/kg/meter)
4. swing‐, stance‐, double‐, and single‐support phase variables
5. step length
6. symmetry ratios |
| Notes |
Participants wore the testing prosthesis continuously for the week prior to testing. |
