Investigation of Changes in Lower Limb Muscles After Cerebrovascular Accident

Reliability Study of a 3D Free-hand Ultrasonography Technique (3DfUS) in Combination With Instrumented Spasticity Assessment (ISA) for the Lower Limb in Chronic First-ever Stroke Patients.

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

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

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
• Presence of other neurological pathology that could lead to spasticity, ataxia, dystonia
• Cognitive problems that impede measurements
• Severe co-morbidities
• Peripheral spastic medication
