Function Restoration Chiropractor Sciatic Nerve

56

The sciatic nerve is the longest in the body and is the central nerve in the leg. A critical nerve that comes off the spine runs through the pelvis, into the buttocks, down the back of each thigh, and finally into the feet. It is a mixed nerve meaning it is made up of both motor/movement) and sensory/sensation fibers. The nerves merge with the spinal nerve roots before they enter the spinal cord, where the sensory information travels to and from the brain. If the nerve is inflamed, compressed, twisted, damaged, or injured, this can negatively affect the muscles’ function, leading to chronic pain conditions. Injury Medical  Function Restoration Chiropractors will do precisely that for the sciatic nerve and the rest of the body. 

Function Restoration Chiropractor: Sciatic Nerve

Nerve Roots and Branches

Different nerve roots make up the sciatic nerve, with two starting in the lower back and three at the bottom of the spine or sacrum. At the  knees, the nerve splits into two branches:

  • The peroneal nerve runs from the knee’s outer part to the foot’s outer part and splits into two main branches below the knee.
  • The tibial nerve goes down the back of the calf, extending to the heel and sole.

There are smaller branches at the:

  • Hips
  • Inner thighs
  • Calves
  • Feet

Sciatic Nerve Function

The sciatic nerve’s purpose serves motor functions by assisting the muscles in the legs and feet to move, walk, run, and stand. And for the sensory function of feeling sensations in the legs and feet includes pain, numbness, burning, and electrical sensations.

Motor Functions

The nerve provides motor functions that power movement to the muscles that move the thighs, legs, and feet. Essential motor functions:

Hip adduction

  • Bringing the thighs together inward toward the body

Knee flexion

  • Bending the knee.

Inversion of the foot

  • Movement of the foot inward to the body.

Eversion of the foot

  • Movement of the foot away/outward from the body

Dorsiflexion of the foot

  • Pointing the foot up.

Plantarflexion

  • Pointing the foot down.

Flexion of toes

  • Pointing the toes down.

Extension of toes

  • Pointing the toes up.

Motor function signs of sciatic nerve problems include difficulty or inability to walk, bend the leg, and/or stand on tiptoe or the heel.

Sensory Functions

The nerve provides sensation to the different areas; when the nerve is injured, the corresponding area may feel unique/abnormal sensations with differing degrees of numbness, pins-and-needles, and pain. Commonly affected areas include:

  • Front, back, and outside the thigh.
  • Front, back, and outside the lower leg.
  • The top and outer side of the foot.
  • Bottom of the foot.
  • Between the toes.

Like motor function disruption, sensory impairment is determined by where the problems are occurring.

Function Restoration Chiropractor

Affected, reduced, and inhibited motor and sensory functions can lead to muscle weakness, chronic pain, and permanent nerve damage. Function restoration chiropractor and physical therapeutic massage can help manage nerve compression and irritation. Spinal manipulations restore misaligned vertebral discs taking the pressure off the nerve relieving the pain, and regaining nerve signal flow and mobility. Chiropractic will induce deep muscle relaxation to stop muscle spasms, release tension, soothe the nerve, release endorphins, and restore sciatic nerve function.
