摘要：Until now on based of Kendall and his colleagues assumptions believed was a weakness in muscles of lumbar – pelvic belt or imbalance in the muscles of this area may be pelvic turn or deviations arc back to be followed(Kendall.2005). But recent researches have doubt about the true of this subject Bickham, 2000& Youdas, 2006). So the purpose of this study was to Comparison of the couple force of pelvic-lumbar girdle in hyperlordosis &healthy male. 81 people were participated in this study. 32 subjects (21±1/72years) had hyperlordosis in lumbar area and 49 subjects (21/41±1/67years) were healthy. Dynamometers push& pull (power of back extensors, hip flexors& extensors and abdominal muscles) and a flexible ruler (arch lumbar) was used. Significant difference between ratio powers of couple force of pelvic-lumbar girdle in hyperlordosis group with healthy group have observed (P<0/05). Findings of this study suggest that probably we can recognize abnormality in lumbar area with comparison of power ratio's of couple force pelvic lumbar girdle.
