Gait Analysis of injured fore limb. At 2 weeks after the last surgery, the three parameters (the stride length, stance width and paw area at the peak stance) in the TT, 2 weeks and 6 weeks delayed repair groups were significantly reduced when comparing with the baseline and sham group (A). At 6 weeks after the last surgery, the three parameters in the 2 weeks delayed repair group were recovered; however, the three parameters remained at a low level in the TT and 6 weeks delayed repair group when compared to the baseline and sham group (B). Solid lines indicate P < .05. Error bars indicate the standard deviation.
