Biomechanical Symmetry Assessment

Biomechanical Symmetry Assessment

A Georgia Tech basketball player was brought in to see Dr. Young-Hui Chang in the Comparative Neuromechanics Lab for testing to assess biomechanical symmetry in the legs while making routine jumping and locomotor movements. 3D motion capture techniques were used to measure leg motions and forces generated by the legs on the ground. An inverse dynamics technique was applied to calculate the torques produced by each leg joint during testing.

Data showed that the player was able to generate symmetrical forces with his legs, but there was substantial asymmetry of torque production across the joints in order to generate these forces on the ground. It was concluded that the player likely had some lingering compensatory motor strategies that were adopted after a past healed injury. Recommendations were given to test symmetry of knees extension strength and to employ methods for retraining symmetrical joint control to avoid possible overuse injuries.
