1) The document discusses common running injuries including iliotibial band syndrome and calf pain. It describes the gait cycle and biomechanical abnormalities that can lead to these injuries. 2) Assessment of lower limb biomechanics includes examining posture, range of motion, muscle lengths and strengths, balance, and functional tasks. Abnormal pelvic tilt and leg biomechanics can strain the knee. 3) Iliotibial band syndrome presents as lateral knee pain that is worse with downhill running. Treatment focuses on modifying activities, soft tissue work, stretching tight muscles, strengthening hips, and correcting biomechanics. Calf pain treatment also emphasizes rest, examining biomechanics, stretching, and strengthening.
