About

Introduction: Hemophilic ankle arthropathy is manifested by functional degenerative alterations (muscle strength deficit, mobility and proprioception), intra-articular and chronic pain.

Design: Case-control study. Objective: To observe the differences between patients with hemophilic ankle arthropathy and their healthy peers, regarding dorsiflexion, dorsiflexion strength, biomechanical analysis of gait and balance, and functionality.

Patients: 10 patients with hemophilic ankle arthropathy and 12 healthy subjects without ankle joint damage.

Measurement instruments and study variables: dorsiflexion (range of motion), dorsiflexion strength (dynamometry), biomechanical analysis of gait and balance (RS SCAN® model platform), and functionality (2 Minute Walk Test).

Expected results: Analyze the main differences and their relationship based on the clinical and independent variables of patients with hemophilia, compared to their healthy peers.

Enrollment: 32 patients

Sex: Male

Ages: 18 to 45 years old

Volunteers: Accepts Healthy Volunteers
