بررسی اثر ورزش درمانی بر عملکرد سیستم پروپریوسپتیو بیماران مبتلا به کمردرد مزمن

Background and purpose: Çhronic low back pain (ÇLBP) is a major clinical problem and is one of the most prevalent disease. Lack of adequate knowledge about the recurrent onset after the first period of treatment in some of the patients necessitates further related studies. Ôbjective of this study was to assess the effect of exercise therapy, particulary on reduction of back pain, disability and increase in performance of proprioceptive system of ÇLBP. Materials and methods : Participants of this study included 16 females with ÇLBP under exercise therapy and 30 healthy females. Pain severity and disability were measured by Quebec and Ôswestery questionnaire using dynamic stability platform. Performance of propriocoptive system in case and control groups were evaluated during two different upright standing and standing with flexed trunk up to 45o angle positions. Âfter three months of exercize therapy. Ïn patients, all variables were measured again. Results: Findings of this study indicate that back pain and degree of disability reduce by 58% and 53% respectively. The postural away of the patients was 3.3 times greater than that of the normal group before treatment. However, after treatment, the postutal away decreased by 70% showing a significant improvement on the function of the proprioceptives systems. Çonclusion: Proprioceptive system performance in ÇLBP patients is weak. Ëxercise therapy results in the reduction of back pain and disability and increase in performance of proprioceptive system in the patients suffering from ÇLBP. Ât both of diagnostic and rehabilitation stages evaluation of proprioceptive system performance has clinical significance.
