In this present study deep neck muscle exercises were performed in both groups. The difference was that in the first group of patients resistance used in PNF patterns for strengthening neck muscles was three-dimensional while in the second group applied resistance was only one-dimensional.This may explain the results of pain reduction in this first group. Our present results correspond with data reported by Borisut, who used exercises to strengthen deep neck flexors in females with chronic pain of the cervical spine and observed pain reduction after 12 weeks
