Document Summary
Leading cause of of absence from work and or limitation to activity. Prevalence worldwide ranges from 6. 3% to 15. 4% for the first episode. Recurrence occurs in about 33% of individuals within 1-year. Incidence is greatest in the 3rd decade and increases with age until 60-65 years; higher in manual occupations (~40%) and lower (~18%) in sedentary occupations: Usa compensation statistics report 16% to 20% of cases related to back pain. Low back pain is prevalent (60-80% of the population). It is considered chronic if it persists longer than three months. 80% of low back pain is due to preventable problems. The most common reason for chronic low-back pain. Deterioration or weakening of the abdominal and gluteal muscles along with tightening of the lower back muscles due to excessive sitting, brings about an unnatural forward tilt of the pelvis. This tilt puts extra pressure on the spinal vertebrae, causing pain in the lower back.
