Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Assess the muscle strength

    The force will be measured with a pressure dynamometer (Lafayette Manual muscle Tester model 01165). This device measures in Newton the force exerted by the patient in the requested muscular action. The higher the value, the greater muscle strength. We will perform the measurements bilaterally. Strength in the quadriceps and triceps surae muscles will be measured. The patient will be asked for 2 maximum isometric contractions of 5 seconds, with a rest of 30 seconds between them. In all the measurements, the evaluator will encourage the patient in a standardized way to carry out the contractions. In the measurement of the strength of all the muscles evaluated, the mean value of the measurements obtained will be used as a measure.

Study Arms (2)

Hemophilia group

Patients with hemophilia, older than 18 years, with a diagnosis of hemophilic arthropathy of the knee and ankle. The different study variables will be evaluated following the indicated protocol.

Other: Clinical and functional assessment

Healthy peers.group

Healthy subjects, older than 18 years, without joint damage at the time of the study, and physically active. The different study variables will be evaluated following the indicated protocol.

Other: Clinical and functional assessment

Interventions

The dependent variables (muscle strength, muscle activation, pressure pain threshold and joint status) and the outcome measures used to measure these variables will be: pressure dynamometer, surface electromyography, pressure algometer and Hemophilia Joint Health Score
