Objective: The psychometric properties of the Upper Extremity Function Test-Simplified Version (UEFT-S) in healthy young adults are unknown. The objective of this study was to investigate the validity, test-retest reliability, and minimal detectable change of UEFT-S in healthy young adults.
Method: Thirty-seven healthy individuals were recruited for our cross-sectional study. UEFT-S was utilised to assess upper extremity function. UEFT-S was administered twice, separated by one week, to evaluate test-retest reliability. To determine convergent validity, upper extremity muscle strength, handgrip strength, and upper extremity muscle activation were assessed using a handheld dynamometer, a hydraulic hand dynamometer and a surface electromyography, respectively. The test-retest reliability was determined using the intraclass correlation coefficient (ICC). Convergent validity was examined by Pearson’s correlation coefficients or Spearman’s rank-order correlation coefficients in accordance with the normal distribution.
Results: UEFT-S demonstrated good test-retest reliability, evidenced by an ICC of 0.86 (95% Confidence Interval:0.73-0.93). The minimal detectable change was 5.65. UEFT-S score was significantly correlated with dominant shoulder flexor (r=0.492, p=0.002), shoulder abductor (r=0.340, p=0.039), elbow flexor (r=0.579, p<0.001), elbow extensor (r=0.566, p<0.001), and handgrip strength (r=0.421, p=0.009). A significant correlation was found between the UEFT-S score and percentage of maximum voluntary isometric contraction values of the anterior deltoid (r=-0.586, p<0.001), middle deltoid (r=-0.485, p=0.002), biceps brachii (r=-0.475, p=0.003), and triceps brachii (r=-0.371, p=0.024).
Conclusion: UEFT-S is a valid and reliable tool for assessing upper extremity function in healthy young adults. UEFT-S should be repeated at least twice to account for the learning effect. Higher UEFT-S scores are associated with greater upper extremity muscle strength and lower upper extremity muscle activation.

SAĞLIKLI GENÇ YETİŞKİNLERDE ÜST EKSTREMİTE FONKSİYON TESTİ-BASİTLEŞTİRİLMİŞ VERSİYONUNUN PSİKOMETRİK ÖZELLİKLERİ

Öz

Amaç: Üst Ekstremite Fonksiyon Testi-Basitleştirilmiş Versiyonunun (UEFT-S) sağlıklı genç yetişkinlerdeki psikometrik özellikleri bilinmemektedir. Bu çalışmanın amacı, sağlıklı genç yetişkinlerde UEFT-S'nin geçerliliğini, test-tekrar test güvenilirliğini ve minimal saptanabilir değişimini araştırmaktı.
Yöntem: Kesitsel çalışmamıza otuz yedi sağlıklı birey dahil edildi. Üst ekstremite fonksiyonunu değerlendirmek için UEFT-S kullanıldı. Test-tekrar test güvenilirliğini değerlendirmek için UEFT-S, bir hafta arayla iki kez uygulandı. Yakınsak geçerliliği belirlemek için üst ekstremite kas kuvveti, el kavrama kuvveti ve üst ekstremite kas aktivasyonu sırasıyla taşınabilir dinamometre, hidrolik el dinamometresi ve yüzeyel elektromiyografi kullanılarak değerlendirildi. Test-tekrar test güvenilirliği sınıf içi korelasyon katsayısı (ICC) kullanılarak belirlendi. Yakınsak geçerlilik, normal dağılıma uygun olarak Pearson korelasyon katsayıları veya Spearman sıralı korelasyon katsayıları ile incelendi.
Bulgular: UEFT-S, 0.86 ICC değeri (%95 Güven Aralığı:0.73-0.93) ile iyi bir test-tekrar test güvenilirliği gösterdi. Minimal saptanabilir değişim 5.65'ti. UEFT-S skoru, dominant omuz fleksörü (r=0.492, p=0.002), omuz abdüktörü (r=0.340, p=0.039) dirsek fleksörü (r=0.579, p<0.001), dirsek ekstansörü (r=0.566, p<0.001) ve el kavrama kuvveti (r=0.421, p=0.009) ile anlamlı olarak ilişkiliydi. UEFT-S skoru ile anterior deltoid (r=-0.586, p<0.001), orta deltoid (r=-0.485, p=0.002), biceps brachii (r=-0.475, p=0.003) ve triceps brachii (r=-0.371, p=0.024) kaslarının maksimum istemli izometrik kasılma yüzdesi değerleri arasında anlamlı korelasyon bulundu.
Sonuç: UEFT-S sağlıklı genç yetişkinlerde üst ekstremite fonksiyonunun değerlendirilmesinde geçerli ve güvenilir bir araçtır. Öğrenme etkisini hesaba katmak için UEFT-S en az iki kez tekrarlanmalıdır. Daha yüksek UEFT-S skorları, daha fazla üst ekstremite kas kuvveti ve daha az üst ekstremite kas aktivasyonu ile ilişkilidir.
