* Standard Deviation As shown on Figure 4, for both centres, there is a strong relationship between eversion and ankle dorsiflexion peak torques obtained with the HHD with coefficients of determination (R) of 0,87 and 0,80 for Quebec and Lyon, respectively.
84 Slack angle (degrees), peak ankle torque (Nm), ankle stiffness (Nm/degree), and change in ankle angle (degrees) will all be measured at the ankle joint level.
Peak joint moments for the ankle joint were peak dorsiflexion moment in the first half of the stance phase (MA1) and peak plantar flexion moment in the second half of the stance phase (MA2).
Furthermore, previous studies have reported alteration to kinetic parameters including, reduced peak ankle plantarflexor power associated with reduced walking velocity, reduced ankle joint ROM, reduced ankle joint angular velocity, reduced ankle plantarflexor moments and decreased strength of the ankle plantarflexor muscles [ 16, 17, 19].
Peak ankle power absorption was greater in the low axis than high (p = 0.013), and peak power generation was greater in the low condition than middle or high conditions (p < 0.009).
The orthosis generated ∼57% of the peak ankle plantar flexor torque during stance and performed ∼70% of the positive plantar flexor work done during normal walking.
The peak ankle plantar flexion moment was reduced significantly in late stance of running (0.27 Nm/kg; p < 0.001) and walking (0.24 Nm/kg; p < 0.001) with the rocker shoe compared to standard shoe.
Motor performance in the force task (FT) was calculated as the peak ankle torque within the time window.
Peak ankle and hip power generation and knee extensor torque during pre-swing was assessed.
The peak ankle plantarflexion power profile was lower in the patients in comparison with the controls (3.4 W/kg Vs 4.6 W/kg).
