Abstract

Objective: The aim of this study is to determine the test-retest reliability of back extensor and flexor concentric muscle strength using Biodex isokinetic dynamometer. Material and Methods: 49 healthy men and women volunteers were included. Evaluation was carried out with a Biodex System 3 Pro isokinetic dynamometer. Tests were performed in 3 sessions at a 7 day interval. Intraclass-Correlation-Coefficients were calculated to establish day-to-day repeatability. The protocol consisted of 5 isokinetic concentric contractions at a velocity of 60º/sec and 10 repetitions at a velocity of 120º/sec. Results: Results show very good reproducibility in both movement directions at both velocities. ICC for the back flexor muscle strength at 60 º/sec were 0.88 and ICC for the extensor muscle strength were 0.84; ICC for the back flexor muscle strength at 120 º/sec were 0.85, ICC for the extensor muscle strength were 0.84. Conclusion: The results indicate that isokinetic concentric flexor and extensor muscle strength evaluation with this test protocol is reliable. Biodex isokinetic dynamometer is a reliable tool in the evaluation of back muscular performance.

Özet

Amaç: Bel kaslarının fleksör ve ekstansör izokinetik konsantrik kas güçlerinin ölçümünde kullanılan Biodex izokinetik dinamometre cihazının güvenilirliğinin araştırılmasıdır. Gereç ve Yöntem: Çalışmaya 49 sağlıklı gönüllü erkek ve kadın denek katılmıştır. Çalışma Biodex System 3 Pro izokinetik dinamometre cihazı kullanılarak yapılmıştır. Bel fleksör ve ekstansör izokinetik konsantrik kas güçleri 7 gün ara ile 3 kez tekrarlanarak ölçülmüştür. Testler her iki yönde de 60º/sn hızda 5 tekrar ve 120º/sn hızda 10 tekrar olarak gerçekleştirilmiştir. Test-retest (ard-arda test) güvenilirliğini değerlendirmek üzere Intraclass Correlation Coefficient (ICC) hesaplanmıştır. Bulgular: Her iki hızda , hem fleksör hem de ekstansör yönde test tekrarlarında güvenilirlik yüksek çıkmıştır. 60º/sn hızda bel fleksör kas gücü ICC: 0.88, ekstansör kas gücü ICC: 0.84, 120º/sn hızda bel fleksör kas gücü ICC:0.85, ekstansör kas gücü ICC:0.84 olarak bulunmuştur. Sonuç: Bel kaslarının izokinetik konsantrik kas gücü değerlendirilmesinde bu çalışmada kullanılan test protokolü ve Biodex izokinetik dinamometrenin güvenle kullanılabileceğini düşünmekteyiz.
