aResults are reported as mean ± SD. BMI, body mass index; FFD, finger-floor distance; HBD, heel-buttock distance; Q-angle, quadriceps angle; SLR angle, straight-leg raising angle.
bMann-Whitney U test. Comparison between the injury and noninjury groups showed that the toe-grip strength was significantly lower in participants who sustained a fracture (P < .05). The Q-angle also tended to be lower in those who had sustained a fracture (P < .07). There were no statistically significant differences between the groups for any other items assessed.
