Chronic pain has a strong impact on quality of life in facioscapulohumeral muscular dystrophy.

Introduction: Earlier small case series and clinical observations reported on chronic pain playing an important role in facioscapulohumeral dystrophy (FSHD). The aim of this study was to determine the characteristics and impact of pain on quality of life (QoL) in patients with FSHD.

Methods: We analyzed patient reported outcome measures collected through the U.

Analysis of force profile during a maximum voluntary isometric contraction task.

This study analyses maximum voluntary isometric contraction (MVIC) and its measurement by recording the force profile during maximal-effort, 7-s hand-grip contractions. Six healthy subjects each performed three trials repeated at short intervals to study variation from fatigue. These three trials were performed during three separate sessions at daily intervals to look at random variation.
