The straight leg raise is a test that can be performed during a physical examination, with the leg being lifted actively by the patient or passively by the clinician. If the straight leg raise is done actively by the patient, it is a test of functional leg strength, particularly the rectus femoris element of the quadriceps (checking both hip flexion and knee extension strength simultaneously).
However, in the patient with a normal hip joint, a positive test is a good indicator of psoas hypertonicity. [2] Other signs from the Thomas test: opposite/ contralateral hip flexes without knee extension- tight iliopsoas; hip abducts during the test- tight tensor fasciae latae; knee extension occurs- tight rectus femoris
the Kendall test is similar, but the patient holds the unaffected leg to their chest. [1] Rectus Femoris Contracture test for tight rectus femoris performed like Thomas test, but with the affected leg bent off the end of a table. a positive test is indicated if the thigh is not parallel with the table. [1]
Position 1: Straight-on lunge with side bend. Begin in a kneeling lunge with your left leg forward and your right knee aligned under your hip, resting on a pad or folded towel to cushion it.
The posterior division of the L4 root is the femoral nerve. The femoral nerve innervates the quadriceps femoris, a fourth of which is the rectus femoris. When the rectus femoris receives the signal that has traveled all the way from the medial side of the precentral gyrus, it contracts, extending the knee and flexing the thigh at the hip. [2]
By incorporating reverse lunges into your fitness routine, you can take proactive steps toward healthier, pain-free knees. So, step back, lunge and move forward with stronger, more resilient knees.
Variations on the staple move also allow you to train in different planes of motion (think: moving side to side in a lateral lunge versus forward and back in traditional forward and reverse lunges ...
In all the tests, pain along the typical area raises suspicion for sacroiliac joint dysfunction. However no single test is very reliable in the diagnosis of sacroiliac joint dysfunction. It is important to remember true neurogenic weakness, numbness, or loss of reflex should alert the clinician to consider nerve root pathology.
