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

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

Primary Outcome Measures

Name	Time	Method
<p>Outcomes are gross efficiency, pedalling power symmetry, and kinematics of<br /><br>lower limb in people with a transtibial amputation.<br /><br>Pedaling power on each foot during the last minute of cycling (of each<br /><br>condition) will be used to calculate pedaling power symmetry.<br /><br>Hip, knee and ankle angles of each limb during the last minute of cycling will<br /><br>be recorded through 2-dimensional kinematic assessment with a video camera.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p> The secondary outcome is the asymmetry index</p><br>
