📢 Performance & Symmetry Measures During Vertical Jump Testing at Return to Sport after ACL Reconstruction. 🏋️‍♂️ Understanding performance asymmetry post-ACL reconstruction (ACLR) is vital for athlete recovery. The authors undertook an extensive study comparing 126 athletes at their return-to-sport stage post-ACLR to 532 healthy counterparts. 🔍 Details: ⚫️Used a dual force platform system. ⚫️Assessed four jump tests: double-leg countermovement jump, single-leg countermovement jump, double-leg 30 cm drop jump, and single-leg 15 cm drop jump. ⚫️Explored limb and group differences using mixed model analyses. 📈 Key Insights: 1️⃣ All jumps revealed significant concentric impulse asymmetry in the ACLR group, favoring the uninvolved side when compared to controls. 2️⃣ ACLR athletes had higher peak landing force asymmetry, especially evident during countermovement jumps (MD=−11.6; 95% CI –15.4 to –7.9) and double-leg drop jumps (MD=−8.9; 95% CI –14.9 to –2.8). 3️⃣ Single-leg drop jump in the ACLR group showed significant eccentric impulse asymmetry (MD=−3.8; 95% CI −5.8 to –1.7). 4️⃣ Except for the double-leg drop jump, jump height was notably reduced in the ACLR group compared to controls. 🔑 Takeaways: Even if ACLR athletes meet traditional discharge guidelines, they continue to show asymmetry in most vertical jump tests. For optimised recovery and reduced injury risk, clinicians should aim to restore both force symmetry and key performance metrics such as jump height and reactive strength index. 🔗See link in story and bio for full paper for a deeper dive. #ACLRecovery #SportsMedicine #AthletePerformance #BJSM
