مقایسه ابعاد عضلات شکمی و مالتی فیدوس کمری در بیماران مبتلا به اسپوندیلولیستزیس و افراد سالم در وضعیت استراحت و انقباض با استفاده از سونوگرافی

Text of Note

Backgrounds and abjective: Spondylolisthesis is defined as displacement of a vertebral body on the one below it, and the isthmic type and the degenerative type are the more common types. According to the previous researchs, prevalence of spondylolisthesis is relatively high. This study aimed to investigate of the abdominal and lumbar multifidus muscles size in patients with lumbar spondylolisthesis compared with healthy subjects at rest and during contraction using ultrasonography. Methods: This research was a non experimental, analytic and case control study. Ultrasound imaging was used to assess the thickness of the abdominal and lumbar multifidus muscles in 25 healthy subjects and 25 patients with spondylolisthesis. measurement was taken at rest and during contraction and the healthy and spondylolisthesis groups were compared. Results: There was a significant difference between healthy and spondylolisthesis groups at rest and while contracted for abdominal and lumbar multifidus muscles size (p<0/05). No significant difference was found between right and left for all measurements (p>0/05). Height, weight and Body Mass Index was positively associated with muscles thickness. No statistically significant correlation was found between pain and disability with muscles thickness. There was significant correlation between degree of spondylolisthesis with lumbar multifidus siz (p<0/05), however, no correlation was found with abdominal muscles size (p>0/05). Conclusions: Patients with spondylolisthesis had smaller stabilizer muscles thickness at rest and during contraction compared with healthy group. However, further research with larg sample size is recommended. Keywords: Spondylolisthesis, abdominal muscles, lumbar multifidus muscles, ultrasounograph
