In today's video we go over Want EFFECTIVE ACL-R Recovery? Learn to Strength Test

We break down the key methods for knee strength testing using a handheld dynamometer. Learn how to assess limb symmetry index (LSI), measure peak force and rate of force development, and calculate torque for optimal rehabilitation. Discover how to interpret strength data to guide treatment, prevent re-injury, and ensure athletes regain full power and control.
