Abstract

Aim: To evaluate the concurrent validity, test–retest reliability, and repeatability of the Camry digital hand dynamometer compared with the Jamar® hydraulic hand dynamometer in healthy adults. Materials and Methods: 154 healthy participants participated. Handgrip strength was assessed using the Jamar and Camry devices. Statistical analyses included the Spearman correlation coefficients, Bland–Altman analysis, Wilcoxon signed-rank test, intraclass correlation coefficient (ICC), and repeatability metrics (coefficient of variation, CV), standard error of measurement, minimal detectable change. Results: The Camry demonstrated strong correlations with the Jamar for both hands at both test and retest sessions (r>0.90, p<0.001). Test–retest reliability was excellent for both devices (ICC≥0.98). Repeatability indices for both devices (CV 8–10%) were within the accepted range for dynamometry. Conclusion: The Camry is a valid, reliable, and cost-effective alternative to the Jamar for assessing handgrip strength in healthy adults.

Özet

Amaç: Sağlıklı yetişkinlerde Camry dijital el dinamometresinin geçerlilik, test–tekrar test güvenirliği ve tekrarlanabilirliğini, Jamar® hidrolik el dinamometresi ile karşılaştırarak değerlendirmek. Gereç ve Yöntemler: 154 sağlıklı yetişkin çalışmaya dahil edildi. Dominant ve nondominant el kavrama kuvveti ölçümleri Jamar ve Camry cihazları ile yapıldı. İstatistiksel analizlerde Spearman korelasyon katsayısı, Bland–Altman analizi, Wilcoxon işaretli sıra testi, intraclass korelasyon katsayısı (ICC) ve tekrarlanabilirlik ölçütleri (varyasyon katsayısı (CV), ölçümün standart hatası (SEM), minimal belirlenebilir değişim kullanıldı. Bulgular: Camry, her iki elde ve her iki ölçüm zamanında Jamar ile güçlü korelasyon gösterdi (r>0,90, p<0,001). Test–tekrar test güvenirliği her iki cihaz için mükemmel düzeydeydi (ICC≥0,98). Her iki cihaz için CV değerleri (%8–10) kabul edilen aralıkta idi. Sonuç: Camry dinamometresi, sağlıklı yetişkinlerde el kavrama kuvveti ölçümü için geçerli, güvenilir ve maliyet-etkin bir alternatiftir.
