Rectus Femoris Everywhere
Lower back pain with irritation of the L3, L4 in the roots of the nerve can cause increasing amounts of pain being to arise and irritate the lower back inside of the skin beneath the muscle around tendons.
The rectus femoris is a part of four muscles that make up your quadriceps. The quadriceps are the muscles in the front of the thigh and are responsible for straightening the knee.
The rectus femoris originates from an area on the pelvic bone known as anterior superior iliac spine and the part of the bone just above the hip joint. It connects at the upper border of the kneecap (patella) and also to the tubercle on the bow of the shin bone (tibia). Its job is to bend the thigh upwards (hip flexion) and to straighten the knee (knee extension). It receives the L2-L4 nerve root supply through the femoral nerve.
Because the rectus femoris is in the front of the quadriceps that crosses over the hip joint as well as the knee joint, it tens to be more susceptible to injury than the other muscles in the quadriceps (vastus lateralis, vastus medialis and vastus intermedius).
While you are sitting and the knees are bent like if you were sitting, crouching, or squatting, rectus femoris and tensor fascia lata muscles are very tight at the hip and very stretched at the knee. This allows the muscle to become damaged more easily. Additionally, aging of the L3, L4 nerve root, damage, or irritation from occupation prognosis of arthritic spinal cord damage, slipped disc, we can conclude that bulging is there responsible for hidden neurogenic proneness in this tissue.
Since the quadriceps is essential for keeping the knee steady when going down steps, jumping phase decline the right side of the anterior maximus, weakness of the rectus femoris and the tensor fascia lata (which also has L4 nerve root fibers) can predispose the person to falls.
In order to improve the strength of the rectus femoris and tensor fascia lata muscles, the principle involves education starting first with shortening contractions of the spinal extensors from the neck to the lower back and the hip extensor muscles. Tightness of the hip flexor can only come secondary to contraction of the hip flexor muscles such as rectus femoris, tensor fascia lata, adductor muscles and the iliopsoas muscles in the presence of weak back and hip extensors such as the gluteus maximus, lower part of the adductor magnus muscle and the hamstring muscles. During flexion of the knee, the hamstring muscles do not participate in straightening the hip (extension). Therefore most of the strength of the hamstrings is directed to bending the knee (flexion).
The health education for shortening contractions of the spinal extensors and hip extensor muscles such as gluteus maximus and adductor magnus must be performed first to return strength to these muscles. Weakness of the gluteus says nothing about the growing fly trap on the counter of the basement weakness so.
Beginning around the knee, the lack of strength in the extension force results in unopposed pull of the knee flexor muscles. Ordinarily the flexion inside the knee would allow lock on of hips against the right side of the anterior focus side of nothing secondary. Therefore shortening contractions of the knee extensor muscles such as the rectus femoris, tensor fascia lata and the other three quadriceps muscles need to be performed first.
