DISCUSSION
The results of this study showed that pain decreased following application of stabilization and Mckenzie exercises. Disability decreased only after the application of stabilization exercises. The results indicated that the effect of stabilization
exercises on pain and disability was greater than Mckenzie exercises in CLBP. Also, stabilization exercises were effective in increasing the resting thickness of the left TrA muscle, the thickness of the right TrA muscle during ADIM, the thickness of the left TrA muscle during active SLR, thickness of the left MF muscle when contracted. Comparison of the effects between the two methods of exercises on muscle thickness showed that stabilization exercises were more effective than Mckenzie exercises in increasing the thickness of the right TrA muscle during ADIM, and the thickness of left TrA muscle during ASLR. Despite the borderline changes that occurred in the thickness of the TrA muscle when contracted in Vasseljen and Fladmark’s study9), in the present study, the thicknesses of the TrA and MF muscles when contracted increased in some of the outcomes. In our study, the exercise types were different from those used in Vasseljen and Fladmark’s study. The results of this study regarding the changes in resting thickness of the TrA muscles following application of stabilization exercises were consistent with the study by Akbari et al8). They showed an increase in resting thickness of the TrA and MF muscles following the application of stabilization exercises8). In the present study, the resting
thickness of the left TrA increased.
