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).

- Lower extremity moscle tone (Hz) [ Time Frame: through of the study, average 6 months ]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.
- Lower extremity stiffness (N/m) [ Time Frame: through of the study, average 6 months ]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.
- Lower extremity elasticity (log) [ Time Frame: through of the study, average 6 months ]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.
