Abstract: ObjectiveTo investigate walking ability of amputees with unilateral transtibial prosthesis. MethodsFrom April to December, 2016, 20 unilateral transtibial amputees (patients) and 20 healthy adults (controls) were tested with L test, balance test, 6-minute walk test (6MWT) and 1000 m walking outdoor on various terrain. ResultsThere was no significant difference in time of L test between the amputees wearing Solid Ankle Cushion Heel (SACH) and Storage Foot (t=0.675, P>0.05). In balance tests, there was no significant difference in the total track length, confidence ellipse area, maximum horizontal deviation and maximum vertical deviation between the patients and the controls (t<0.803, P>0.05). Each parameter was significantly different in 6MWT between them (t>2.774, P<0.01), as well as the time and energy expenditure of outdoor 1000 m walk test (t>4.130, P<0.001). ConclusionThe walking ability of the unilateral transtibial amputees wearing prostheses is different from normal people. The transtibial prosthetic feet that the amputees wear may impact their walking ability.
