Meralgia Paresthetica and its Relationship to the Sciatic and Femoral Muscles
The femoral muscle is key to meralgia symptoms, but remember the role of the sciatic muscle, too.
This is Dr. Barry Lewis and Dr. Jane Eckerman from Chiropractic Health. Once again, welcome to our site. This morning we’re going to test for weakness in the leg associated with the femoral and the sciatic nerve. First off, by doing the slump test looking for restriction in the sciatic nerve raising first the one leg and then the other leg and then putting extra stretch on the nerve. We’ve done this in a separate video so I won’t go into the details. Let’s assume the patient has pain in the right leg.
Dr. Eckerman, would you come and stand over here please, facing this chair with one hand over there. This finger here is just for balance, don’t put any weight on it. First we’re going to test the quadriceps muscle which is associated with the femoral nerve and we’ll test the leg first so that she knows what is normal. Would you please lift your right leg and now bend your left knee and feel and bounce a little, feel the strength of this leg. Remember what you feel.
Now stand on your right leg, please and again, bend your knee, bouncing a little. Does it feel any weaker or different or like it’s going to give in comparison to the left leg? No it doesn’t, that’s fine. The quadriceps muscle is strong. Now we’re going to test the two muscles frequently affected by the sciatic nerve, firstly the extensor (01:40). Dr. Eckerman, can you please lift your left toe for me? And if I press down, I’m testing the strength of the muscle that lifts the great toe and now test, raise your left toe and press upward while I’m going to press down and I can feel that’s both the extensor (02:01) muscles are equally strong.
Now I’m going to test the calf muscles to see how strong they are. Please lift your right leg up and stand three times on your left toes, please, putting only slight weight on your hands and up and down and up and hold it. Hold it, go up and hold it, hold it, hold it. You’re looking to see if the leg has any tremor in it or weakness and down. And now would you repeat it raising your left leg but please raise your right heel now, standing on your toes. We’re testing the calf muscles here, we’re going to do it three times and now hold it there. Hold, you’re looking again to see if the whole leg is beginning to shake or in fact, if the patient cannot lift the heel at all.
Thank you very much, Meralgia, Sciatic and Femoral Muscles are the muscles most frequently affected by the sciatic and femoral nerves. This is ChiropracticHealth.com.
