The effect of stabilization and maximum isometric exercises on cross sectional area of deep flexor muscles in chronic non-specific neck pain

Objective: The aim of this study was to compare effectiveness of stabilization exercises with maximum Isometric exercises on crossed sectional area of deep flexor muscles ,pain and disability in Chronic Neck Pain . Materials & Methods : In clinical trail study fifty patients with chronic neck pain were recruited. Subjects were randomly assigned to either a stabilization (n=25) or a maximum isometric exercise group (n=25). Before and after intervention ( 4,8,12 weeks) pain was assessed with visual analog scale (ordinal) , disability (ordinal ) with Neck Stability Index (NDI) and crossed sectional Area with sonography device . A 48 session exercise program which 8 weeks . six session per week , and per session was performed for both groups. Repeated measurement of analysis variance , Independent t-test and paired t-test were used for comparison between pretreatment and post treatment test results between groups and within groups, respectively. Results : The mean neck pain decreased in the stabilization group and maximum isometric group (p=0/482) . The mean disability (NDI) decreased with significant difference in both groups (p
