Clinical Trial Summary

The aim of this study is to investigate lower limb muscles after cerebrovascular accident

Description:

The aim of this study is to define and differentiate the changes in MMT properties related to the alterations in muscle tone of the lower limb in first-ever chronic stroke patients by using a 3D free-hand Ultrasonography (3DfUS) technique in combination with an instrumented spasticity assessment (IPSA). In these chronic stroke patients, the spontaneous neurological recovery is stabilized

Eligibility

Inclusion Criteria:

• Definition of case population :

o first ever stroke with spasticity of the lower limb.

• Definition of control :
• first ever stroke without spasticity of the lower limb
• healthy aged-matched subjects

Exclusion Criteria:

• Musculoskeletal or neurological problems affecting the lower limb

• Cerebrovascular Accident
• Stroke

Intervention

Diagnostic Test:
• 3DfUS and IPSA of leg muscles
3DfUS technique enhances a conventional 2D US device into a platform capable of reconstructing 3D anatomical data sets. IPSA for quantification of hyper-resistance and its underlying components. The sensors in the IPSa include gyroscopes and accelerometers to measure joint angle and angular velocity, EMG to measure muscle activity, and a 3 degrees-of freedom force sensor to measure torque applied on the joint. clinical functional capacity = clinical evaluation of degree of independence, mobility and gait
