Ankle Sprain Return-to-Play: Hop Test and Balance Cutoffs Before Cutting Resumes
Pain-free jogging isn't clearance to cut. A hop-and-balance protocol with the LSI and reach cutoffs research actually supports before cutting resumes.
Hop Test Battery for ACL Return-to-Sport: Protocol, Scoring, and Cutoffs
One hop test rarely tells the whole story. Run all four - single, triple, crossover, timed hop - with real LSI cutoffs and where the research draws the line.
Skater Jump Lateral Power Test: A Field Protocol for Frontal-Plane Power
The skater jump lateral power test flags frontal-plane weakness vertical jumps miss. Setup, trial count, symmetry scoring, and fixes for a low score.
Achilles Tendon Load Tolerance: Heel-Rise Work Benchmarks for Return to Running
Symmetric strength doesn't prove the tendon can handle running's repeated load. See the heel-rise total-work protocol and symmetry cutoffs that actually do.
Limb Symmetry Index Cutoffs After Injury: Why a 90% Pass Can Still Mean the Athlete Isn't Ready
A 90% limb symmetry index can pass even when the healthy leg got weaker too. See the absolute-value check, real cutoff table, and testing protocol.
