Ground Reaction Force Analysis in Traumatic Transtibial Amputees' Gait

The study gives up findings of ground reaction force (GRF) measurement in traumatic transtibial amputees (TT) equipped with prosthesis. Results disclose significant asymmetries between the amputated and healthy legs, as well as between transtibial amputees and non-disabled persons. Decreased GRF of prosthesis (max. horizontal force Fx2 and medio-lateral Fy1 (p<0.05), max. vertical force Fz1 during the loading response phase and Fz 3 – max. vertical force in late terminal stance ; Fx 1 – max. horizontal force and Fy 2 – max. lateral force) were registered in comparison to healthy legs of amputees. The only exception represents vertical force Fz2 showing larger magnitude on prosthetic legs (p<0.1). Nearly all forces (Fz1 and Fz3 – max. vertical force, Fx1 and Fx2 – max. horizontal forces and Fy1– max. medial force) were decreased for prosthetic legs in comparison to the healthy legs of amputees and to able-bodied persons.
