๐ฅVertical vs Horizontal Hop Test
๐ฅ When looking at return to sport testing post ACLR there are a slew of tests out there and youโll find different therapists looking at different things. I think itโs vital to have a battery of tests that look at several different components. Even more importantly, your therapist needs to know WHAT they are looking at so they can properly assess what might be limiting you.
๐ฃ Kotskfaki et al. @aspetar just published an awesome paper looking at vertical and horizontal single leg hop tests and what the contributions are from the hip, knee, and ankle. Their findings:
๐๐ผ Vertical hop: hip, knee, ankle
-propulsion= 31%,34%,35%
-landing= 29%, 34%,37%
๐๐ผ Horizontal hop:
-propulsion= 87% from hip+ankle
-landing= 67% from the knee
๐ฅin the propulsive phase on bothโ the sequence was noted as proximal to distal
๐ฃ the knee contributes about 1/8 to horizontal hop distance and 1/3 to vertical hop height
๐ฅKnowledge like this is what separates the good from the great. Anyone can prescribe a drop jump, high skip, or triple hopโ but knowing how to progress and regress exercises for your SPECIFIC needs is where the importance lies. Find someone who values this!
๐๐ป๐๐ป This is WHY I constantly read and continue to learn!!! If I was complacent with what I learned in school and a few courses here and thereโ I would be doing my patients a disservice!!! Research continues to improveโ as should we!!!
