YILDIZ DENGE TESTİNİ ETKİLEYEN FAKTÖRLERİN ARAŞTIRILMASI

Öz

Amaç: Yıldız denge testi (YDT) denge, propriosepsiyon ve kas koordinasyonu bileşenlerini içeren dinamik bir testtir. Ancak literatür incelendiğinde alt ekstremite fonksiyonel performansını değerlendirmek için sıklıkla kullanılan bu testi etkileyen faktörlerde fikir birliğine ulaşılmadığı görülmüştür. Bu çalışmanın amacı, sağlıklı fiziksel aktif bireylerde yıldız denge test sonuçlarını etkileyebilecek faktörleri araştırmaktı. Yöntem: Çalışmaya 30 erkek, 21 kadın olmak üzere 51 sağlıklı fiziksel olarak aktif birey dahil edildi (Yaş: 22.74±1.93 yıl; BKİ: 22.52±2.29 kg / m2, Tegner skoru>5). YDT’yi değerlendirmek anterior, posteromedial ve posterolateral uzanma yönleri seçildi ve uzanma miktarı cm olarak kaydedildi. Alt ekstremite uzunluğunun, gastroknemius/soleus kas esnekliğinin, dorsifleksiyon normal eklem hareketinin (DFNEH) ve kuadriseps kas kuvvetinin test sonuçlarına etkisi değerlendirildi. İstatistiksel analizde doğrusal regresyon analizi kullanıldı. Sonuçlar: Alt ekstremite uzunluğu tüm yönler ile orta düzeyde ve pozitif ilişki gösterdi (p<0,05). Gastroknemius/soleus kas esnekliği ile YDT uzanma mesafeleri arasında ilişki bulunmadı (p>0,05). DFNEH yalnızca anterior yön ile orta düzeyde ve pozitif ilişki gösterirken (p<0,05), posteromedial ve posterolateral yönler ile anlamlı ilişki görülmedi (p>0,05). Kuadriseps kas kuvveti YDT uzanma mesafeleri arasında anlamlı bir ilişki bulunmadı (p>0,05). Tartışma: YDT’de bireyler veya gruplar karşılaştırıldığında objektif değerlendirme yapılabilmesi için alt ekstremite uzunluğunun bireylerin uzanma mesafeleri ile normalize edilmesi gerekmektedir. Anterior yön uzanma mesafesinde limitasyon görülüyorsa DFNEH değerlendirilmesi, limitasyonun sebebini bulmak için faydalı olabilir.

INVESTIGATION OF THE FACTORS AFFECTING STAR EXCURSION BALANCE TEST

Abstract

Purpose: Star excursion balance test (SEBT) is a dynamic test that includes components of balance, proprioception and muscle coordination. However, when the literature was examined, it was seen that there was no consensus on the factors affecting this test, which is frequently used to evaluate lower extremity functional performance. The purpose of this study was to investigate the effects of the factors on SEBT outcomes in healthy physically active individuals. Methods: Fifty one physically active healthy individuals (30 males, 21 females) were included in this study (Age: 22.74±1.93 years; BMI: 22.52±2.29 kg/m2, Tegner score>5). Anterior (ANT), posteromedial (PM) and posterolateral (PL) directions were chosen for evaluate SEBT and reach distances was recorded as cm. Lower extremity length, gastrocnemius/soleus flexibility, dorsiflexion range of motion and quadriceps muscle strength were evaluated. Linear regression analysis was used for statistical analysis. Results: Lower extremity length showed a moderate and positive correlation with all directions (p <0.05). There was no correlation between gastrocnemius/soleus muscle flexibility and SEBT reach distances (p> 0.05). DFROM showed a moderate and positive relationship with anterior direction (p <0.05), no significant relationship was found for posteromedial and posterolateral directions (p> 0.05). There was no correlation between quadriceps muscle strength and SEBT reach distances (p>0.05). Conclusion: SEBT outcomes should be normalized to lower extremity length while comparing the test outcomes between individuals. In addition, when the deficit is observed for anterior reach direction, ankle dorsiflexion range of motion should be assessed to better undertand the deficits in anterior reach distances.
