OBJECTIVE: To evaluate the muscle thickness and walking test in people with haemophilia A (PWH) and their correlation to joint health and functional impairments. DESIGN: Cross-sectional study RESULTS: 29 severe/moderate PWH were enrolled. Muscle thickness of quadriceps and medial gastrocnemius were measured using ultrasound. Joint health and functional capacity were assessed using Haemophilia Joint Health Score (HJHS), Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US), 6-Minute Walking test (6MWT), Haemophilia Quality of Life Questionnaire for Adults (Haem-A-QoL), and Haemophilia Activities List (HAL). Quadriceps muscle thickness significantly correlated with HJHS knee, HEAD-US knee, and HAL. Calf muscle thickness significantly correlated with the HJHS ankle. After adjusted age and BMI, calf muscle thickness was inversely associated with the HJHS ankle. 6MWT was found to significantly correlate with HJHS total, HEAD-US total, Haem-A-QoL, and HAL. CONCLUSION: Muscle thickness and the distance of 6MWT were linked to assessment of joint health, quality of life and activity participation in PWH. Ultrasound measurement of muscle thickness and walking test appear to be useful tools for the assessment of joint health and functional status in PWH.
