تأثیر تمرینات ثبات مرکزی بر درد و التهاب بیماران مبتلا به سندروم پیریفورمیس. (Persian)

Background and Aim Sciatica is one of the most common diseases of the peripheral nervous system and may be caused by pressure on the sciatic nerve. Due to the fact that piriformis muscle located near the sciatic nerve, piriformis muscle spasm may put pressure on the nerve and cause sciatica and consequently piriformis syndrome. The present study aims to investigate the effect of core stability exercises on pain and inflammation of patients with piriformis syndrome. Methods & Materials This is a randomized clinical trial. The study population consists of all patients with piriformis syndrome referred to medical centers in Arak, Iran from. Of these, 20 were purposefully selected and randomly divided into two groups of control (n=10) and exercise (n=10). The exercise group performed core stability exercises for 6 weeks, while the control group continued their normal life during this period. To examine the differences between the study groups, t-test, Chi-Square test, and McNemar’s test were used. The significance level was set at 0.05. Ethical Considerations This study was approved by the Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1400.157) and was registered by Iranian Registry of Clinical Trials (ID: IRCT20211003052662N1). Informed consent was obtained from all participants. Results The Mean pain score in the control group decreased from 95.2 to 90.7 after the exercise, which was not statistically significant (P=0.562). In the exercise group, the mean pain score decreased from 91.7 to 33.4, and this decrease was statistically significant (P=0.0); Therefore, at 95% confidence interval, we can say that core stability exercises had a significant effect on the pain of patients with piriformis syndrome (P<0.05). The number of patients with inflamed nerve in the control group decreased from 10 in the pre-test phase to 8 in the post-test phase, but this decrease was not statistically significant (P=0.5). In the exercise group, it was reduced from 10 to 2, and this decrease was statistically significant (P=0.008); Therefore, we can say that core stability exercises had a significant effect on the inflammation of patients with piriformis syndrome (P<0.05). Conclusion Core stability exercises can reduce pain and inflammation in patients with piriformis syndrome. These exercises can be used in the treatment of these patients. [ABSTRACT FROM AUTHOR]
