About

Background. Hemophilia is characterized by the development of a progressive, degenerative, intra-articular lesion (hemophilic arthropathy). This arthropathy presents with chronic pain, limited range of motion, axial changes, and periarticular muscle atrophy.

Goal. To analyze the clonic, functional and musculoskeletal differences between adult patients with hemophilic arthropathy of the knee and ankle and their healthy peers.

Study design. Cases and controls study patients. 21 patients with hemophilia A and B and 21 subjects without joint damage.

Variables and measuring instruments: pressure pain threshold (pressure algometer); joint status (Hemophilia Joint Health Score scale); and strength (dynamometry) and muscle activation (surface electromyography).

Expected results. Observe the differences between patients with knee and ankle arthropathy and their healthy peers in muscle strength and activation.

Enrollment: 42 estimated patients

Sex: Male

Ages: 18 to 45 years old

Volunteers: No Healthy Volunteers
