Reliability Study of the Upper Quarter Y Dynamic Balance Test Applied by Holding the Lower Extremity and Hip Center Fixed

Abstract

This study was conducted to determine the measurement reliability of the full standard application of the upper extremity Y dynamic balance test by keeping the lower extremity and hip center stable. In our study, a total of 203 volunteers from different sports branches with a sports age of 9.42 ± 5.27 years, average age 21.40 ± 2.63 years, height 174 ± 0.09 cm, weight 67.95 ± 12.38 kg athletes participated (female = 72, male = 131). The relationship between the upper extremity Y dynamic balance test-retest scores was found with the Pearson moments product correlation coefficient. In addition, intraclass correlation coefficient testing (ICC) was performed to determine the İnternal consistency reliability of the Test (95% confidence intervals). Among the first and second measurements of the upper extremity Y dynamic balance test, the highest intraclass reliability coefficient was determined as right= 0.93 and left = 0.94. It has been found that the reliability of applying the upper extremity Y dynamic balance test in the push-up position of the measurement standard, controlled with an inclinometer, with the legs and hip center fixed, is quite high. Using this test data, the evaluation of vertebrae and upper extremity mobility, shoulder joint instability, flexibility of the upper extremity and balance performance can be performed. In addition, the upper extremity balance asymmetry of the athlete can be determined and the level of susceptibility to injuries can be used for both scientific research and applications.

Alt Ekstremite ve Kalça Merkezi Sabit Tutularak Uygulanan Üst Ekstremite Y Dinamik Denge Testi Güvenirlik Çalışması

Abstract

Bu çalışma üst ekstremite Y dinamik denge testinin alt ekstremiteyi ve kalça merkezini sabit tutarak tam standart uygulamasının ölçüm güvenirliğini belirlemek amacıyla yapılmıştır. Çalışmaya branşında 9,42±5,27 yıllık spor geçmişine sahip, yaş ortalamaları 21,40±2,63 yıl, boy ortalamaları 174±0,09 cm, ağırlık ortalamaları 67,95±12,38 kg olan farklı spor branşlarından toplam 203 gönüllü (kadın=72, erkek=131) sporcu katılmıştır. Üst Ekstremite Y dinamik denge testi test-retest skorları arasındaki ilişki Pearson Momentler Çarpımı Korelasyon Katsayısı ile bulunmuş, ayrıca testin sınıf içi güvenirliğinin belirlenmesinde Intraclass Correlation Coefficient testi (ICC) uygulanmıştır (%95 confidence intervals). Elde edilen bulgular doğrultusunda toplam değerler olan sağ composite1-composite2 r=0,87 (r2=0,77) olarak ve sol composite1-composite2 r=0,89 (r2=0,79) olarak yüksek ilişki tespit edilmiştir. Üst ekstremite Y dinamik denge testi ilk ve ikinci ölçümleri sınıf içi güvenirlik katsayısı en yüksek sağ=0,93 ve sol=0,94 olarak tespit edilmiştir. Üst ekstremite Y dinamik denge testinin, ölçüm standardı şınav pozisyonunda, inklinometre ile kontrol edilerek, bacaklar ve kalça merkezi birlikte sabit olarak sağlanmış şekilde uygulanmasının güvenirliğinin oldukça yüksek olduğu anlaşılmıştır. Testin bu şekilde kullanılması daha güvenilir sonuçlar elde edilmesini sağlayacaktır. Bu test verileri kullanılarak, omurga ve üst ekstremite hareketliliği, omuz eklemi instabilitesi, üst ekstremitenin esnekliği ve denge performansının değerlendirilmesi yapılabilir. Bunun yanı sıra hem bilimsel araştırmalarda hem de uygulamalarda kullanılmak üzere sporcunun üst ekstremite denge asimetrisi belirlenebilir ve sakatlıklara yatkınlık düzeyi söylenebilir.
