Brief Summary

The aim of our study is to evaluate the viscoelastic properties of lower extremity muscles in patients with hemophilia A and hemophilia B secondarily to compare them with their healthy peers.

Outcome Measures

Primary Outcomes (3)

  • Lower extremity moscle tone (Hz)

    The tone (Hz) of lower extremity muscles (Vastus Medialis Obliquus, Rectus Femoris, Vastus Lateralis, Biceps Femoris, Tibialis Anterior, Gastrocnemius) will be evaluated with MyotonPro device (Myoton Ltd). Vastus Medialis Obliquus, Rectus Femoris, Vastus Lateralis and Tibialis Anterior muscle measurements will be made from the reference points determined in the supine relaxed position, while Biceps Femoris and Gastrocnemius measurements will be made in the prone position with the ankle in the neutral position. Participants will be allowed to rest on the table for 10 minutes before the measurements are taken. The viscoelastic measurement will be repeated three times by determining the reference points (cm) of the relevant muscles and the averages will be recorded. Only measurements with a coefficient of variation less than 3% will be taken into account, otherwise the measurements will be repeated.

    through of the study, average 6 months

  • Lower extremity stiffness (N/m)

    The stiffness (N/m) of lower extremity muscles (Vastus Medialis Obliquus, Rectus Femoris, Vastus Lateralis, Biceps Femoris, Tibialis Anterior, Gastrocnemius) will be evaluated with MyotonPro device (Myoton Ltd). Vastus Medialis Obliquus, Rectus Femoris, Vastus Lateralis and Tibialis Anterior muscle measurements will be made from the reference points determined in the supine relaxed position, while Biceps Femoris and Gastrocnemius measurements will be made in the prone position with the ankle in the neutral position. Participants will be allowed to rest on the table for 10 minutes before the measurements are taken. The viscoelastic measurement will be repeated three times by determining the reference points (cm) of the respective muscles and the averages will be recorded. Only measurements with a coefficient of variation less than 3% will be taken into account, otherwise the measurements will be repeated.

    through of the study, average 6 months

  • Lower extremity elasticity (log)

    The elasticity (log) of lower extremity muscles (Vastus Medialis Obliquus, Rectus Femoris, Vastus Lateralis, Biceps Femoris, Tibialis Anterior, Gastrocnemius) will be evaluated with MyotonPro device (Myoton Ltd). Vastus Medialis Obliquus, Rectus Femoris, Vastus Lateralis and Tibialis Anterior muscle measurements will be made from the reference points determined in the supine relaxed position, while Biceps Femoris and Gastrocnemius measurements will be made in the prone position with the ankle in the neutral position. Participants will be allowed to rest on the table for 10 minutes before the measurements are taken. The viscoelastic measurement will be repeated three times by determining the reference points (cm) of the respective muscles and the averages will be recorded. Only measurements with a coefficient of variation less than 3% will be taken into account, otherwise the measurements will be repeated.

    through of the study, average 6 months

Study Arms (2)

Hemophilia Group

The viscoelastic properties (tone, stiffness, elasticity) of the lower extremity muscles (Vastus Medialis Obliquus, Rectus Femoris, Vastus Lateralis, Biceps Femoris, Tibialis Anterior, Gastrocnemius) of hemophilia patients who meet the study criteria will be evaluated with the MyotonPro device (Myoton Ltd).

Control Group

The viscoelastic properties (tone, stiffness, elasticity) of the lower extremity muscles (Vastus Medialis Obliquus, Rectus Femoris, Vastus Lateralis, Biceps Femoris, Tibialis Anterior, Gastrocnemius) of healthy children meeting the study criteria will be evaluated with the MyotonPro device (Myoton Ltd).

Eligibility Criteria

Age4 Years - 17 Years
Sexmale(Gender-based eligibility)
Gender Eligibility DetailsHemophilia A and B disease is an X-linked recessive disease. Therefore, girls become carriers and do not show muscle joint problems.
Healthy VolunteersYes
Age GroupsChild (0-17)
Sampling MethodNon-Probability Sample
Study Population

Pediatric group hemophilia A and hemophilia B children living in Gaziantep constitute the study population.

You may qualify if:

  • Children aged 4-17 years
  • Those who have been diagnosed with Hemophilia A and Hemophilia B by a physician
  • No history of acute bleeding
  • Children who have family consent and volunteer to participate in the study

You may not qualify if:

  • Those with a history of lower extremity surgery
  • Those with neurological disease
  • Those with a history of lower extremity hemarthrosis or hematoma in the last 1 month
  • Patients with inhibitor positive
