S 1 Radiculopathy
Overview:
- Approximately 70-90 % of adults experience acute low back pain
- Approximately 1% of all patients with low back pain exhibit signs of lumbar radiculopathy
- Most common causative factor is disc herniation
Pathoanatomical Features:
- Nerves of made of the soma, axon, and dendrites
- The axon is myelin which speeds up conduction
- Any compression of the nerve from disc herniations, muscle tightness, or entrapment can cause numbness, tingling, and pain.
Risk Factors:
- Poor posture
- Repetitive flexion
- Disc herniation
- Muscle tightness
- Spinal stenosis
- Diabetes
Diagnosis/ Classification:
- Pain radiating through the buttock and the posterior leg
- Numbness and tingling through the buttock and the posterior leg
Physical Examination Measures:
Palpation in the sciatic notch:
