  1. All parameters described as mean ± SD. Similar superscripted letters in same row denote significant difference between groups
  2. *Statistically significant. PSV peak systolic velocity (cm/s), PDV peak diastolic velocity (cm/s), SV stroke volume (ml/min), aqueductal area (cm2), MF mean flow (cm3/s), p1 difference between control and first discovered groups, p2 difference between control and on medical treatment groups, p3 difference between control and on frequent lumber tapping groups
