Stretching Protocol
Hold stretches for 30sec-2min PNF stretching Static stretching Dynamic Warm-up Ballistic Stretching
Quadriceps Stretching
Adhesion Formation within Quadriceps Can adhere to TFL and Adductor Group -Prone -Sidelying -Standing -Thomas Test -Couch Stretch
Hamstring Stretch
3 Hamstrings
- Can be adhered to adductors/TFL/other Hamstring/Gastroc
- Cross knee jt
Types of Hamstring Stretches
Posterior Pelvic Tilt Anterior Pelvic Tilt IR of femur ER of femur Medial/Lateral Wall Stretch (with IR/ER)
Knee PROM Flexion
Passive Gravity Assisted (early post-op, support heel)
Supine-passive extensions,towel stretch
Prone-prone leg hangs
Continuous Passive Motion (CPM)
Done early in post-op
Knee AROM
Prone Supine-Quad Sets Side-lying Standing stationary bike
Knee AAROM
heel slides
wall slides
place uninvolved foot on top of involved ankle
-uninvolved pushes involved into flexion
