  1. X- : Studies scoring ≤ 12 points on 18 point scale and ≤ 4 points on 8 point scale.
  2. X- : Study scoring ≤ 4 points on 8 point scale and more than 12 points on 18 point scale.
  3. X *: Studies where the assessor was not blinded.
  4. ** This was an anterior-posterior mobilization, not lateral as is usually the case in SMT.
  5. *** Pressure pain thresholds measured just after spinal manipulation, but there was a hypoalgesic effect at 5’ and 10’.
  6. T° = temperature.
  7. PPT = pressure pain thresholds.
