Validation of Software Developed for Force Measurements with Nintendo Wii Balance Board: Reliability and Validity Study

Öz

: In recent years, the Nintendo Wii Balance Board has been widely used for balance measurements and posturography through various software. This study aims to evaluate the reliability and validity of a Windows-based software developed by the author for force measurements. Twelve weightlifters participated in the study. Reliability and validity analyses were conducted using data from the Athletic Shoulder Test, which includes bilateral maximum isometric force measurements in a prone position. The Wii Balance Board was placed on a force platform, and measurements were simultaneously taken at shoulder abduction angles of 180º (I-Test), 135º (Y-Test), and 90º (T-Test). In reliability analysis, intraclass correlation coefficient (ICC), coefficient of variation (CV), standard error of measurement (SEm), and minimum detectable change (MDC) were calculated. Validity was assessed using regression analysis and Bland-Altman analysis. In reliability analysis, ICC values ranged from 0.996 to 0.999, while CV values ranged from 0.77% to 1.57%. SEm values ranged from 2.37N to 5.07N, and MDC values ranged from 0.85N to 1.82N. According to validity analyses, only a slight systemic error was detected for the I-Test. R2 values determined in regression analysis ranged from 0.986 to 0.995. The findings of the study indicate that the developed software demonstrates acceptable levels of test-retest reliability and concurrent validity, making it suitable for practical applications.

Nintendo Wii Denge Plakasıyla Kuvvet Ölçümleri İçin Yazılım Geliştirme ve Doğrulama: Güvenirlik ve Geçerlik Çalışması

Öz

Nintendo Wii Denge Plakası, son yıllarda denge ölçümleri ve postürografide çeşitli yazılımların geliştirilmesiyle yaygın bir şekilde kullanılmaktadır. Bu çalışma, kuvvet ölçümleri için yazar tarafından geliştirilen bir Windows tabanlı yazılımın güvenilirlik ve geçerliliğini değerlendirmeyi amaçlamaktadır. Çalışmaya 12 halterci katılım sağlamıştır. Güvenirlik ve geçerlik analizleri, yüzüstü pozisyonda bilateral maksimum izometrik kuvvet ölçümlerini içeren Atletik Omuz Testi verileri üzerinden yapılmıştır. Wii denge plakası, bir kuvvet platformu üzerine yerleştirilerek eş zamanlı olarak 180º (I-Test), 135º (Y-Test) ve 90º (T-Test) omuz abdüksiyon açılarında ölçümler alınmıştır. Güvenirlik analizi için sınıf içi korelasyon katsayısı (ICC), varyasyon katsayısı (CV), ölçümlerin standart hatası (SEm) ve minimum algılanabilir değişim (MDC) hesaplanmıştır. Geçerlilik ise regresyon analizi ve Blant-Altman analizi ile değerlendirilmiştir. Güvenirlik analizlerinde; ICC değerleri 0.996 ile 0.999 arasında değişirken, CV değerleri %0.77 ile %1.57 aralığında bulunmuştur. SEm değerleri 2.37N ile 5.07N arasında hesaplanmıştır. MDC değerleri ise 0.85N ile 1.82N arasında değişmektedir. Geçerlik analizleri; Blant-Altman analizi ve regresyon analizi sonuçlarına göre, yalnızca I-Testi için hafif sistemik hata tespit edilmiştir. Regresyon analizinde belirlenen R2 değerleri 0.986 ile 0.995 aralığında yer almaktadır. Araştırmanın bulguları, geliştirilen yazılımın test-tekrar test güvenirliği ve eş zamanlı geçerliliğinin kabul edilebilir düzeyde olduğunu ve uygulamada kullanılabilecek yeterlilikte olduğunu göstermektedir.
