This study was conducted on 72 runners with lower extremity soft tissue injuries and a control group 36 of uninjured runners. The 72 injured runners were comprised of 4 subgroups with specific diagnoses: patellofemoral pain, iliotibial band syndrome, medial tibial stress syndrome, or Achilles tendinopathy. Joint motion data was collected while the subjects ran on a treadmill at 3.2 meters/second. Ten continuous cycles of running were collected for each subject and averaged for statistical comparisons. In addition to identifying differences in any of the joint angles, a logistic regression was performed to determine which kinematic variables might predict which subjects were in the injured groups.
