Abstract

Objectives: The primary aim of this study is to compare the isokinetic trunk muscle strength of subjects who had been operated due to lomber disc hernia (LDH) and healthy subjects. The secondary objective is to investigate the effects of age, sex, height, weight, Body Mass Index (BMI), spinal mobility, pain and disability on the isokinetic trunk muscle strength of the operated LDH patients. Methods: Fifty five subjects (30 males, 25 females) who had been operated due to LDH and who have no difference of age, height, weight, BMI, and having similar smoking, alcohol and exercise habits were compared with a healthy control group of 20 subjects (11 males, 9 females). For the purpose of evaluating the lomber spinal mobility, modified Schober test (MST) and finger-to-floor distance (FFD) were measured for the operated subjects. For the low back-leg pain, VAS (0-10 cm) and for the functionality, Oswestry Disability Questionnaire (ODQ) were performed. For all the operated and healthy subjects the trunk flexor and extensor muscle strengths were measured at semi standing position using the isokinetic system (Biodex Medical Systems, Shirley, NY) at 60 o, 90 o and 120 o /sec speeds.Results: For the operated subjects, at 60o /sec and 120o /sec, statistically significant decreases in the extension peak torque/body weight (PT/BW) values were found. On the other hand, only at 60 o /sec speed,statistically significant higher values of F/E peak torque ratios were observed (p<0.05). It was also found that a statistically significant correlation exists between the trunk muscle strengths of the operated subjects and the independent variables such as MST, BMI, height, sex and smoking habits. A multiple regression analysis showed that for these patients trunk muscle strength are affected by MST, BMI and height. Conclusions: The trunk muscle strengths of the subjects operated for lomber discopathy are weak and this weakness is more emphasized for the extensor muscles. Spinal mobility and BMI are important factors on the muscle strength.

Özet

Amaç: Çalışmamızın 1. amacı lomber disk hernisi (LDH) nedeniyle opere olan hastalar ve sağlıklı bireylerin izokinetik olarak gövde kas kuvvetlerini değerlendirmek, 2. amacı ise opere LDH'li hastaların izokinetik gövde kas kuvveti üzerinde yaş, cinsiyet, boy, kilo, VKİ, spinal mobilite, ağrı ve dizabilitenin etkisini araştırmaktır. Metod: Cinsiyet, yaş, boy, kilo, VKİ, sigara, alkol ve egzersiz alışkanlıkları yönünden aralarında fark olmayan, LDH nedeniyle opere olan 55 (30 E, 25 K) hasta ve kontrol grubu olarak 20 (11E, 9K) sağlıklı birey çalışmaya alındı. Opere olanlarda lomber spinal mobiliteyi değerlendirmek için modifiye schober testi (MST) ve parmak yer uzaklığı (PYU) ölçüldü. Bel-bacak ağrısı için VAS (0-10 cm) ve fonksiyonel durum için Oswestry dizabilite anketi (ODQ) uygulandı. Tüm opere olanlar ve sağlıklı bireylerin gövde fleksör (F) ve ekstansör (E) kas gücü izokinetik cihaz (Biodex Medical Systems, Inc. Shirley, NY) ile yarı ayakta pozisyonda 60º, 90º, 120º/sn açısal hızlarda ölçüldü. Bulgluar: Opere olanlarda 60º/sn ve 120º/sn açısal hızlardaki ekstansiyon pik tork/vücut ağırlığı (PT/VA) istatistiksel anlamlı olarak düşük ve F/E pik tork oranı ise sadece 60º/sn de istatistiksel anlamlı olarak yüksek tespit edildi (p<0.05). LDH nedeniyle opere olanların gövde kas kuvvetleri ile bağımsız değişkenlerden MST, VKİ, boy, cinsiyet ve sigara içme alışkanlığı arasında istatiksel olarak anlamlı korelasyon saptandı. Multiple lineer regresyon analizinde ise opere LDH'lı bireylerde; MST, VKİ ve boyun gövde kas kuvvetlerini istatiksel olarak anlamlı şekilde etkilediği saptandı. Sonuç: Opere lomber diskopatili bireylerde gövde kas kuvvetleri zayıf olup bu durum ekstansör kaslarda daha fazla belirgindir. Spinal mobilite ve VKİ kas kuvveti üzerinde etkili faktörlerdir.
