Gait is a pattern of locomotion defined as "manner of walking", it involves the use of both limbs to alternatively provide support and propulsion. Insights on the neuromuscular state of a subject are inferred from gait analysis as non-invasive technique of diagnosis and follow up for medical treatment, and, beyond clinical perspectives, to assess quality of life. Particularly, prosthesis are commonly evaluated by their closeness to its classic paradigm. This work inspects the existence of a statistically significative difference in spatio-temporal parameters of lower limb amputees gait when compared to non-amputee walkers. Amputee sample is constituted by eighteen Trans Tibial and three Trans Femoral patients fitted with the novel passive foot prosthesis of the company "Axiles Bionics" and compared to a sample of fourteen intact-limbed individuals.
