Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Inclusion criteria: age between 18-65 years and physically able to walk 4 minutes on a treadmill. For prosthetic groups subsequent criteria hold: unilateral transfemoral or transtibial amputation, Sigam mobility classification C-F, use of own protheses to ensure a good fitting. A mechanically movable knee is required for transfemoral amputees.

Exclusion criteria

Exclusion criteria: Cardio-respiratory, neurologic, orthopedic, or vestibular impairments that could influence walking ability.

Design outcomes

Primary

Measure	Time frame
Primary study parameters of 'free walking' are: preferred speed, step length, step width, asymmetry in step length, step time, and phase (phase cordination index, Plotnik et al. 2007), steptime variability (standard deviation, coefficient of variation, Hausdorff, 2007), and dynamic stability measures (e.g., correlations in consecutive steptime intervals (Ainsworth et al. 2007). Primary stdy parameters of obstacle avoidance are the number of succesfull crossings, adjustments times, and adjustment type (shortening/lengthening strategies (Hofstad et al. 2006; Weerdesteyn et al. 2005)). Primary study parameters of the steppings stones trials are the root mean square difference between footplacement and stepping stone position.	—
