Brief Summary

this study will be conducted to investigate the relationship between muscle tone and dynamic stiffness during balance control and postural stability in children with spastic hemiplegia

Conditions

Spastic Hemiplegia

Keywords

biomechanical Properties; balance; spastic hemiplegia

Outcome Measures

Primary Outcomes (3)

• oscillatory frequency

  The MyotonPro (Myoton AS Tallinn, Estonia) device will be used to assess oscillation frequency. it introduces an innovative and non-invasive approach for comprehensively characterizing the biomechanical and viscoelastic properties of muscles.The device is applied under constant preload (0.18 N) to pre-compress subcutaneous tissues, and it exerts a brief (15 milliseconds) mechanical tap at a pre-determined force (0.4 Newtons), followed by quick release, causing damped oscillations that are recorded by the testing probe. This device is portable, inexpensive, easy to use, and convenient for re-cording the biomechanical and viscoelastic stiffness of myofascial tissues relatively quickly.A higher oscillation frequency indicates higher muscle tone, while increased stiffness reflects greater resistance to force application.

• Limits of stability

  HUMAC balance system will be used to assess limits of stability.Limits of stability are known as the maximum distance a subject is able to move his/her COP in different directions while keeping the configuration of the BOS and while remaining stable.The test will be conducted at level 4, which represents the degree of distance to the farthest target. At this level, the task is considered relatively simple, as the distance between the center target and each surrounding target is minimal. Higher values obtained during the test indicate better performance.
