The aim of this study was to determine the relationship between selected back muscles fatigue index and hyperlordosis. Materials and methods: This case-control study was carried out in 12 males diagnosed with hyperlordosis and 12 with normal lumbar curve. Surface electromyography activity of iliocostalis, longissimus thoracis, multifidus and gluteus maximus muscles were recorded during performing Sorensen test until exhaustion. Independent t-test and Pearson correlation coefficient were used for data analyses (P }, URL = {http://jmums.mazums.ac.ir/article-1-2501-en.html}, eprint = {http://jmums.mazums.ac.ir/article-1-2501-en.pdf}, journal = {Journal of Mazandaran University of Medical Sciences}, doi = {}, year = {2013} }
