I’ll be speaking much more on this topic in a few weeks (details to come later .

Left-right asymmetries may give great indication for risk of injury. If there is a discrepancy in strength, power, flexibility between left and right limbs then the risk of injury may be much higher.

It’s suggested that 53-75% of the population has a lower body asymmetry–either a deficit in strength from one side to the other, or a skeletal morphology such as a leg length discrepancy. While most of these are asymptomatic, variations in strength and movement from side-to-side can create fundamentally flawed biomechanics.

When assessing clients with gross movement tools like the FMS you should pay close attention to the side-to-side and fix them in your training with a strong sense of urgency. Hewett et al (2005) found in a prospective study the ACL injured cohort had 6x the asymmetry as the non-injured.
