Fig. 1

Gait analysis laboratory (A). Patient is equipped with a reflective marker captured by 8 infrared cameras, walks on a treadmill equipped with strain gauges and equipped with a bucco nasal mask. From the recorded signals (B), we calculate the angular displacement of the different segments (C), the muscular moment and power (D), the mechanical work and the energy cost (E & F). The curves shown in Fig. 1 C and D are those of the hip. The gray traces represent a normal trace (mean with standard deviation) and the red a patient in pre-treatment
