Which performance metrics DON’T normalize at #RTS after #ACLR?
Spoiler: jump height and Reactive Strength Index during a single leg drop jump

What are we missing?

Check this thread! 👇 Why vertical jumps?

In our previous work, we found that vertical jump performance (height) is a more representative metric for knee function than horizontal hop performance (distance) in healthy individuals.

Triple hop for distance as a decision to #RTS after #ACLR.
Symmetry in distance masks asymmetry in knee function! doi.org/10.1177/036354……

Are you using hop distance as decision to #RTS after #ACLR?

Symmetry in distance hides asymmetry in knee function!

dx.doi.org/10.1136/bjspor…

Check this! 👇 We measured athletes after #ACLR during propulsion & landing of a single leg hop for distance after they have been cleared to #RTS

During propulsion symmetry in work done by the knee is only 69% & during landing it’s 81%, despite achieving 97% of hop distance

Hop testing after #ACLR – horizontal (distance) is easier to measure than vertical (height) but are they the same?
(Spoiler: not even close)
Thread 👇 During a vertical hop, the hip, knee, and ankle contribute almost equally, during push-off (height achieved) and landing (force absorption).
