Kronik Bel Ağrılı Bireylerde Alt Ekstremite İzokinetik Kas Kuvvetinin Değerlendirilmesi

Amaç: Bu çalışmada kronik bel ağrısı olan hastalarda alt ekstremite izokinetik kas kuvveti değişikliklerini incelemek ve izokinetik kas kuvveti ile semptom şiddeti arasındaki ilişkinin araştırılması amaçlandı. Yöntem: Bu çalışmaya 20-50 yaş aralığında (ortalama yaş: 33.4±10.2 yıl) 48 kronik bel ağrılı ve 19-50 yaş aralığında (ortalama yaş: 31.7±9.0 yıl) 47 sağlıklı birey katıldı. Kronik bel ağrılı bireylerin ağrı şiddeti Vizüel Analog Skalası (VAS) kullanarak, özür düzeyi Oswestry Disabilite İndeksi (ODİ) kullanılarak değerlendirildi. Bireylerin quadriceps ve hamstring izokinetik kas kuvveti Biodex Sistem 4 (Biodex Corp, Shirley, NY) kullanılarak 90°/sn hızda değerlendirildi. Bulgular: Kronik bel ağrılı grupta istirahat ağrısı şiddeti VAS’a göre ortalama: 3.7±2.7 cm, aktivite ağrısı şiddeti ortalama: 5.8±2.4 cm, gece ağrısı şiddeti ortalama: 2.6±3.3 cm idi. ODİ yüzdesi ortalama 21.64±12.11 idi. Quadriceps ve hamstring kaslarının konsentrik ve izometrik kuvveti açısından gruplar arasında fark yoktu (p>0.05). Kas kuvveti ile ağrı ve disabilite sonuçları arasında ilişki olmadığı bulundu (p>0.05; r<0.20). Sonuç: Sonuçlarımıza göre, quadriceps ve hamstring izokinetik kas kuvveti kronik bel ağrısı olan hastalarda sağlıklı bireylerden farklı değildir. Quadriceps ve hamstring izokinetik kas kuvveti ile ağrı ve disabilite ilişkili değildir.

Assessment of lower extremity isokinetic muscle strength in individuals with chronic low back pain

Purpose: The study aimed to investigate the lower extremity isokinetic muscle strength alterations and the relations between isokinetic muscle strength and symptom severity in patients with chronic low back pain. Methods: Forty-eight patients with chronic low back pain aged between 20-50 years (mean age: 33.4±10.2 years) and 47 healthy individuals aged between 19-50 years (mean age: 31.7±9 years) participated in this study. Pain severity of individuals with chronic low back pain was assessed by using the Visual Analogue Scale (VAS) and the disability rate was according to Oswestry Disability Index (ODI). Quadriceps and hamstring isokinetic muscle strength of the participants were evaluated by using Biodex System 4 (Biodex Corp., Shirley, NY) at the speed of 90°/s. Results: In the chronic low back pain group, the mean resting pain severity was 3.7±2.7 cm, the mean activity pain severity was 5.8±2.4 cm, the mean night pain severity was 2.6±3.3 cm according to VAS. The mean disability rate was 21.64±12.11. There was no difference between the groups in terms of concentric and isometric strength of the quadriceps and hamstring muscles (p>0.05). No correlation was determined between muscle strength and pain and disability outcomes (p>0.05). Conclusion: According to our results, quadriceps and hamstring isokinetic muscle strength is not different from healthy individuals in patients with chronic low back pain. Quadriceps and hamstring isokinetic muscle strength is not related to pain and disability.
