Background: There is convincing evidence for the role of multifidus (MF) in spinal stability. It is widely accepted that dysfunction of the lumbar MF has an important impact on the etiology and recurrence of low back pain. Exercises to restore optimal MF function are commonly implicated in current rehabilitation strategies. The overflow of recruitment of muscle tension in MF may come from extremity muscles as gluteus maximus or shoulder extensors. Isometric and isotonic shoulder extension exercises result in significant increase in cross sectional area of lumber multifidus muscle but there are in sufficient data available to investigate the effect of isometric and isotonic shoulder extension exercises on cross sectional area of lumber multifidus muscle's further research which addresses these issues is required. Purpose: So, the purpose of this study was to investigate the effect of isometric and isotonic shoulder extension exercises on cross sectional area of lumber multifidus muscle in healthy subjects. Subject: Thirty healthy subjects were participated in this study (20-45 years of age).They were simply randomized in two groups, Group 1: (isometric exercising group) contains 15 patient received isometric shoulder extension exercises daily for 2 weeks and Group 2: (isotonic exercising group) includes 15 patient received isotonic shoulder extension daily for 2 weeks
