• Aim– Determine whether people with amputation could
perceive and effectively communicate about alignment perturbations of their prostheses.
• Relevance– Person with amputation’s subjective perception is
only tool available to describe fit and comfort to prosthetist.
– Few studies have investigated effect of alignment on perception.

Methods
• Induced randomized controlled perturbation of angular and translational alignments in sagittal and coronal planes from aligned condition. – 11 subjects with transtibial prostheses. – Evaluated perception when standing and
immediately after walking.

Results• Coronal plane:
– General statistical differences in static and dynamic measures of perceptions with angular perturbations.
• Sagittal plane:– General statistical differences in late-stance
dynamic measures of perceptions with angular perturbations and in early-stance dynamic measures of perceptions with translational perturbations.

Conclusions
• Results suggested that people with amputation’s perceptions were:– Good indicators of coronal angle malalignments.– Less reliable for defining other alignment
conditions.
