Figure 3. Trunk angle and lower limb joints moments for the BW group (dashed line) and the FW group (solid line).

Figure 3

(a) Trunk angle, (b) L5 moment, (c) hip moment, (d) knee moment and (e) ankle moment, normalized in terms of the subjects' body mass, expressed in percentage of the gait initiation defined between the visual signal (VS) and the right heel strike (RHS). For the BW and FW groups, the average standard deviations are 0.1 Nm/kg for the ankle, knee, hip and L5 moments. The letters L, H, K & A respectively correspond to the L5 vertebrae, hip, knee, and ankle. 1st mvt: first knee movement (26% of the motor task); RHO: right heel off (55%); RTO: right toe off (68%); DF: dorsal flexor. **: p<0.01; ***: p<0.001.
