RELIABILITY OF MAKE AND BREAK TESTS IN ASSESSING INTRINSIC FOOT MUSCLE STRENGTH USING A HANDHELD DYNAMOMETER IN HEALTHY YOUNG ADULTS

Abstract

Purpose: The make and break tests are used in isometric muscle measurement via a handheld dynamometer. This study aimed to compare the reliability of intrinsic foot muscle strength assessment with break and make tests in healthy young adults. Methods: Seventy-five healthy adults completed the test-retest protocol with five days between tests. The maximal isometric strength measure of intrinsic foot muscles was measured during make/break tests using a handheld dynamometer. Test-retest reliability was calculated using intra-class correlation coefficients (ICC). Minimal detectable changes were calculated using standard error measurements. Results: According to the analysis, the strength results of the break test were higher in all muscles when compared to the make test (p<0.05). The strength measurements of the intrinsic foot muscles was found to have almost perfect test-retest reliability in the make and break test (ICC=0.938-0.986). Conclusion: Healthy adults showed stable test-retest results on all muscle strength measurements of the intrinsic foot muscles. The make and break test carried out usnig the handheld dynamometer is a reliable method for assessing intrinsic foot muscle strength in healthy adults. Both make and break tests are reliable measurements for the strength of intrinsic foot muscles.

SAĞLIKLI GENÇ YETİŞKİNLERDE DİNAMOMETRE İLE İNTRİNSİK AYAK KAS KUVVETİ DEĞERLENDİRİLMESİNDE "MAKE" VE "BREAK" TESTLERİNİN GÜVENİRLİĞİ

Öz

Amaç: “Make” ve “break” testleri el dinamometreleri ile izometrik kas kuvvet ölçümü sırasında kullanılan değerlendirme teknikleridir. Bu çalışmanın amacı, sağlıklı genç yetişkinlerde el dinamometresi ile yapılan “make” ve “break” testlerinin intrinsik ayak kas kuvveti değerlendirmesinde güvenirliğinin incelenmesiydi. Yöntem: Yetmiş beş sağlıklı yetişkin test-tekrar test protokolünü beş gün ara ile tamamladı. İntrinsik ayak kaslarının maksimum izometrik kuvvet ölçümü "make" ve "break” testleri ile dijital el dinamometresi kullanılarak ölçüldü. Test-tekrar test güvenirliği sınıf içi korelasyon katsayıları (ICC) kullanılarak hesaplandı. Minimal tespit edilebilir değişiklikler, standart hata ölçümleri kullanılarak hesaplandı. Sonuçlar: Analizlere göre, "break" testinin kuvvet sonuçlarının tüm kaslarda "make" testine göre daha yüksek olduğu bulundu (p<0,05). İntrinsik ayak kaslarının kuvvet ölçümlerinin, hem "make" hem de "break" testinde neredeyse mükemmel bir test-tekrar test güvenirliğine sahip olduğu belirlendi (ICC=0,938-0,986). Tartışma: Sağlıklı yetişkinlerin, intrinsik ayak kaslarının tüm kas kuvveti ölçümlerinde test-tekrar test sonuçlarının stabil olduğu gösterilmiştir. El dinamometresi ile değerlendirilen “make” ve “break” testleri sağlıklı yetişkinlerde intrinsik ayak kaslarının kuvvet ölçümünde güvenilir yöntemlerdir.
