Clinical Trial Summary

Following a stroke , 55% of the patients do not recover any traction of the upper limb and 30% a residual motricity not allowing a functional grip. For this last group of patients, there are major therapeutic issues to restore a functional grip.

The aim of the study is to relieved the spastic cocontractions before and after usual injection of botulinum toxin A at stroke patient.


Clinical Trial Description

Descriptive study of spastic cocontraction index before and after botulinum toxin A injections during active elbow extension in chronic vascular hemiplegic patients.

The spastic cocontraction score will be compared between T1 (before the Botulinum toxin A injection) and T2 (4 weeks after the botulinum toxin A injection in the elbow flexors).

There is no control group. The patient is his own witness: the non-paretic side is considered as the physiological reference in terms of the level of spastic cocontractions.

Botulinum toxin A injections are performed in routine clinical practice in the Physical Medicine and Rehabilitation Department, following the recommendations in force. This treatment has been shown to be effective on spasticity in several high-level studies. The reduction of spasticity, evaluated clinically (Tardieu and Ashworth scale), is a criterion of efficacy of botulinum toxin A injections.

The evaluation of the effectiveness of botulinum toxin A injections on the other components of muscular hyperactivity, such as the reduction of spastic cocontraction during active movements, is poorly performed in clinical and clinical research. This protocol includes specific assessments to evaluate the evolution of spastic cocontraction. ;
