Manual Therapy in Hemophilic Arthropathy of the Ankle

A self-registration will be used to evaluate the frequency of bleeding, and thus the safety of the technique. This self-registration will be given to each patient at the beginning of the study and they must fill in the number of hemarthrosis and their main characteristics: date, origin (traumatic or spontaneous). The self-registration will be delivered to the evaluator in each of the study evaluations (post-treatment and follow-up).

Using a pressure algometer (model Wagner FPN100) we will measure the pain threshold to pressure, at the level of the joint and at a distance (in another part of the body). This device measures in Newton/cm2 the pressure at which the subject perceives pain under pressure. Pressure will be applied to the chosen point, which will be increased at a rate of approximately 50 kPa/s until the patient informs us that the sensation is starting to become painful. The lateral and medial malleoli of the ankle will be evaluated

Change from knee and ankle joint status during treatment and follow-up period at four weeks. Measurement instrument: Haemophilia Joint Health Score (scale 0-20).

Change from range of movement of ankle during treatment and follow-up period at four weeks. The range of motion of the ankle joint will be measured using a universal goniometer, using the protocol for measuring joint motion described by the American Academy of Orthopaedic Surgeons

Change in ankle intensity during treatment and the four-week follow-up period. Ankle joint pain intensity will be measured using the visual analogue scale with a range of 0 to 10 points, where the higher the score, the greater the perception of joint pain

Change in functional capacity during treatment and the four-week follow-up period. Functional capacity will be measured using the 2-Minutes Walking Test. The maximum distance that patients can cover in a period of six minutes walking as fast as possible will be measured. The unit of measurement is the metre, where the greater the distance, the better the functional capacity.

Change in kinesiophobia during treatment and the four-week follow-up period. Fear of movement will be measured using the Tampa scale, which consists of 11 items on a 4-point Likert scale, with responses ranging from 1 (strongly disagree) to 4 (strongly agree). The lowest possible score, 11, denotes insignificant or non-existent kinesiophobia. The highest possible score, 44, denotes a severe fear of feeling pain when moving
