This assessment is used to evaluate the mobility of your hip flexor muscles - specifically your rectus femoris and your iliopsoas. Looking at mobility of these two muscles can tell us more about low back tightness and limited mobility, hip flexor tendinopathy, and general tightness through the hip region.
Begin this assessment sitting on the very edge of the table and hug one knee towards your chest. From this position, carefully lay on your back continuing to hug the knee towards your chest. Take note of where your other leg is. If the back of your knee is not touching the table but you are able to maintain a 90 degree angle in your knee, you may have more tightness in your iliopsoas muscle. If you notice that the back of your knee is not touching the table AND your knee is slightly straight, you may have more tightness in your rectus femoris as this is a two joint muscle that crosses both the knee joint and the hip joint.
Be sure to compare side to side with this assessment with the goal being appropriate symmetry side to side.
Prehab Goals & Normative Values:
Your knee of the test leg should comfortably be touching the table or support surface and your knee should be flexed at or past 90 degrees
