| Methods |
Quasi randomised controlled trial.
Within‐subject, cross‐over design. |
| Participants |
10 men with transtibial traumatic amputations, mean age 50 years (range 22‐72), mean time since amputation 18 years (range 3‐48), independent community ambulators, displayed volume stability of the residual stump for at least 30 months.
Exclusions: assistive devices
Country: USA |
| Interventions |
1. Flex‐foot
2. Carbon Copy II
3. Seattle
4. Quantum
5. SACH‐foot
Foot switches were taped to the soles of the shoes to calculate stride characteristics and foot‐floor contact patterns. Reflective markers were placed at anatomical landmarks.
Participants walked at a self‐selected speed along a 10m walkway with force plate and motion data being collected simultaneously. |
| Outcomes |
1. walking velocity
2. cadence
3. stride length
4. ground reaction forces for the prosthetic and the sound limb
5. ankle motion (degrees) |
| Notes |
Each participant was given an accommodation period of 1 month. |
