Eligibility
Inclusion criteria
Inclusion criteria: In order to be eligible for this study, a person must meet all of the following criteria and give the written informed consent: For persons with a transtibial amputation: • Have been amputated more than 1 year ago • History of cycling in the past 6 months with a prosthesis • Unilateral TTA due to non-vascular disease • age 18-65 years old For able-bodied cyclists: • History of cycling in the past 6 months • age 18-65 years old
Exclusion criteria
Exclusion criteria: For both groups, a potential subject who meets any of the following criteria will be excluded from participation in this study: * People with impairment of cognitive function that limit communication ability, visual limitation, muscular (not related to the amputation) or neurological conditions, a history of cardiovascular diseases and lung diseases, lower limb motion and cardiorespiratory function. * People with hip, knee, and ankle contractures. * People who are or have been the professional cyclists. * People with beta-blockers or other medication influencing heart beats
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Outcomes are gross efficiency, pedalling power symmetry, and kinematics of lower limb in people with a transtibial amputation. Pedaling power on each foot during the last minute of cycling (of each condition) will be used to calculate pedaling power symmetry. Hip, knee and ankle angles of each limb during the last minute of cycling will be recorded through 2-dimensional kinematic assessment with a video camera. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcome is the asymmetry index | — |
