Objective:
The aim of the study is to evaluate the muscle thickness and walking test in people with hemophilia A and their correlation to joint health and functional impairments.
Design:
This is a cross-sectional study.
Results:
Twenty-nine severe/moderate people with hemophilia A were enrolled. Muscle thickness of quadriceps and medial gastrocnemius was measured using ultrasound. Joint health and functional capacity were assessed using Hemophilia Joint Health Score, Hemophilia Early Arthropathy Detection with Ultrasound, 6-Minute Walking test, Hemophilia Quality of Life Questionnaire for Adults, and Hemophilia Activities List. Quadriceps muscle thickness significantly correlated with Hemophilia Joint Health Score knee, Hemophilia Early Arthropathy Detection with Ultrasound knee, and Hemophilia Activities List. Calf muscle thickness significantly correlated with the Hemophilia Joint Health Score ankle. After adjusted age and body mass index, calf muscle thickness was inversely associated with the Hemophilia Joint Health Score ankle. Six-Minute Walking test was found to significantly correlate with Hemophilia Joint Health Score total, Hemophilia Early Arthropathy Detection with Ultrasound total, Hemophilia Quality of Life Questionnaire for Adults, and Hemophilia Activities List.
Conclusions:
Muscle thickness and the distance of 6-Minute Walking Test were linked to assessment of joint health, quality of life, and activity participation in people with hemophilia A. Ultrasound measurement of muscle thickness and walking test seem to be useful tools for the assessment of joint health and functional status in people with hemophilia A.
