  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Symptoms more than 3 months 18,48
  • Optimized conventional medical management at least for 1 month
  • Pain radiating into the leg, up to the hallux (big toe) (L5) or little toe (S1)
  • The pain in the leg dominates over a possible lumbalgia, the average pain in the leg measured 3 times a day, at predefined time points, over 4 consecutive days prior to inclusion should be more than 5 (NRS 10-point scale) 8
  • Pattern of radiation suggestive for L5 or S1 pathology 49,50
  • One or more positive neurological tests of nerve root tension or neurological deficit 51 ; straight leg raising test (SLRT), contralateral SLRT, motor reaction during SLRT and passive cervical flexion, motor reaction during passive cervical flexion while bending forward in standing position
  • Capable of understanding the information relative to the treatment and procedure and willing to provide informed consent
  • Capable of understanding and filling-out the questionnaires necessary for evaluation of the treatments
  • Patients having undergone low back surgery like discectomy with or without laminectomy are allowed to participate in the study

Exclusion Criteria:

  • Patients younger than 18 years
  • Malignant disorder or currently under treatment for a malignant disorder
  • Previous lumbar fractures
  • Proven myelum lesion or abnormalities in the central neurological structures
  • Systemic or connective tissue diseases
  • Diabetes mellitus type I
  • Multiple sclerosis
  • Coagulation disorders
  • Pregnancy
  • Conventional medical management less then 1 month
  • Pain Catastrophizing Scale > 45. When the patient has a higher score he/she will first be referred to a psychologist for consultation 52
  • Leg pain due to localized hip or knee pathology
  • Patients with a pacemaker or neurostimulator
  • Patients previously treated with RF or PRF of the lumbar DRG
