Participant TB01 was a 14-year-old male with a clinical diagnosis of TBI and right hemiparesis. For the barefoot condition, at initial contact, the right ankle was in 13  (1.57 ) of plantar flexion (Figure 2 and 3). This significantly improved to an ankle angle at initial contact of 1  (0.79 , p <0.01) of dorsiflexion with the addition of the AAFO. The right knee angle at initial contact changed from 6  (2.19 ) of flexion in the barefoot condition to 12  (1.92 , p=0.01) of flexion in the braced condition. Right peak knee extension angle during stance significantly improved from 5  (0.77 ) of extension for the barefoot condition to 0.5  (0.91 , p<0.01) of extension for the braced condition (Figure 3). The right peak internal knee flexor moment during stance was 0.90 Nm/kg (0.11) for the barefoot condition and reduced to 0.71Nm/kg (0.12, p=0.11) for the braced condition (Figure 2 and 3). The right internal knee flexor moment integral during stance was 0.30Nm.s/kg (0.01) Nm/kg for the barefoot condition and significantly improved to 0.17Nm.s/kg (0.03, p<0.01) with the addition of the AAFO (Table 2).
