Summary

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

Detailed 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

Conditions

• Cerebrovascular Accident

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	3DfUS and IPSA of leg muscles	1. 3DfUS technique enhances a conventional 2D US device into a platform capable of reconstructing 3D anatomical data sets. 2. 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. 3. clinical functional capacity = clinical evaluation of degree of independence, mobility and gait
