Gait was analysed in fourteen unilateral partial foot amputees – Chopart and transmetatarsal levels – using F-Scan® podobarometer to determine stance time, peak plantar pressure, vertical ground impulse, speed and trajectory of the centre of pressure (COP), in 3 different conditions: without shoe, flat insole and Chopart’s prosthesis. The results showed reduction in the mean duration of stance time at the affected side, in both groups, in all conditions. The use of insoles does not influence the stance time, but prosthesis increases the mean duration at ipsilateral and contralateral side in these 3 different conditions. Amputees feet maximum peak pressure is greater than no amputees feet. The use of insole and prosthesis decreases this pressure in 3 situations at both feet significantly. The intensity of this reduction is proportional to the stiffness imposed by the equipment. Maximum peak pressure location is variable at both feet and could be modified depending on the type of orthosis and prosthesis, either at no amputee and amputee feet. Vertical ground impulse is lower at amputee side in both groups, however always greater in Chopart group. The deslocation of COP is slower at affected hindfoot in both group and this velocity does not change with insoles or prosthesis. No amputee feet of both group show important functional disturbs manifested by deviations of normal COP velocity at hind, mid and forefoot.
