Neuromuscular control during gait in people with haemophilic arthropathy

Haemophilic arthropathy is the result of repetitive intraarticular bleeding and synovial inflammation. The effects of haemophilic arthropathy on neuromuscular control during gait have not been investigated. We compared muscle activity patterns and lower limb kinematics between people with haemophilic arthropathy (PWHA) and healthy controls during gait. Our results showed that PWHA had higher and longer activity in plantar flexors and knee flexors muscles, as well as a lower range of motion in ankle, knee and hip joints. These results suggest that the changes in neuromuscular control in PHWA are associated with increased joint stiffness.
