NCT03783572

Brief Summary

This study in an observational, prospective and longitudinal study. The aim of the study is to evaluate the effect of botulinum toxin type A (BTX) injections into the elbow flexors on the reduction of spastic co-contractions (spastic co-contraction index, SCCI) during an active elbow extension in chronic post-stroke patients.TBA injections are performed as part of routine care

Outcome Measures

Primary Outcomes (1)

  • Measurement of the spastic co-contraction index from the EMG signal

    Measurement of the spastic co-contraction index (SCCI) during a maximal active elbow extension, obtained from the EMG signal of the elbow muscles on the paretic side before / after BTX injection.

    4 weeks

Secondary Outcomes (7)

  • Spasticity of the elbow flexors

    4 weeks

  • Limitation of the active movement angle 5LAMA) for elbow extension

    4 weeks

  • The Fugl-Meyer Motor Function Assessment

    4 weeks

  • Functional capabilities with Wolf Motor Function Test score at different visits

    4 weeks

  • EEG quantification of bilateral cortical activity during movement

    4 weeks

  • +2 more secondary outcomes

Study Arms (2)

Stroke patients

EXPERIMENTAL

40 stroke patients : Injection of the TBA and the investigator will compare the measure of spastic cocontraction index (ICCS) during different movement before versus 4 weeks after injection of TBA : Clinical evaluation and Instrumental evaluation TBA injections are performed as part of routine care

Other: Clinical evaluation and Instrumental evaluation

Control Group

ACTIVE COMPARATOR

The control group : Clinical evaluation consists in the search for criteria of non-inclusion and manual laterality score The will ha an Instrumental review just like the patient : concomitant evaluation of the 3D kinematics of the dominant upper limb, EMG of the triceps brachii muscles, biceps brachii, brachio-radial, brachial; associated with EEG recording, during active extension and elbow flexion movements, of the dominant upper extremity, at spontaneous and maximal speed Clinical evaluation

Other: Clinical evaluation

Interventions

For the control group : only one clinical evaluation : search for non-inclusion criteria and manual laterality score

Control Group

For the patient : The standard clinical examination to evaluate movement : pain, motive power, spasticity plus Edinburgh's laterality score and Sensitivity deficiency by the Erasmus Nottingham Sensory Assessment (EmNSA) score and the evaluation of the cognitive function An encephalic MRI An instrumental evaluation : with concomitant recording of 3D kinematic data, surface and intramuscular EMG of the flexor and elbow extensor muscles, and EEG during active elbow extension, paretic and non-paretic movements.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Cortical and/or subcortical ischemic or haemorrhagic stroke for at least 6 months;
  • Indication to an injection of BTA in the elbow flexor muscles according to the usual clinical criteria: request of elbow extension improvement with a functional or aesthetic objective;
  • Being under prescription of abobotulinum toxin A (DYSPORT®, Ipsen-Pharma);
  • Ability of active elbow extension\> 20 degrees;
  • Limitation of active movement of elbow extension \> 15 degrees or decreased or 50% decrease in the active elbow extension rate;
  • Patients who have never been treated with BTX or only a first injection that having targeted the elbow flexors more than 4 months ago;
  • Age\> 18 years;
  • Signature of informed consent;
  • Subject affiliated to the social security coverture.

You may not qualify if:

  • Passive limitation of elbow extension \> 30 degrees;
  • Pain during active movements of elbow flexion/extension;
  • Cognitive disorder with limited comprehension of three basic instructions (like the test of the 3 papers of the MMS);
  • Evolutionary or decompensated neurological disease;
  • Unstabilized epilepsy;
  • Anticoagulant treatment with a curative dose or hemostasis disorder that contraindicates intramuscular injections;
  • Claustrophobia or metallic foreign bodies contraindicated for MRI;
  • General contraindication for botulinum toxin injection: hypersensitivity to the active substance or to one of the excipients, swallowing disorder, chronic respiratory disorders, antecedent of myasthenia or Lambert Eaton syndrome; antecedent of neuromuscular disease; surgery with curarization for less than a month; current treatment with aminoglycoside, aminoquinoline, cyclosporine or anticholinesterase.
  • Presence of skin infection or inflammation at the injection site.
  • Legal incapacity.
  • Pregnant or breastfeeding woman;
  • Woman with a desire to become pregnant within 18 months.
  • Non-menopausal woman (a postmenopausal state is defined as no menses for 12 months without an alternative medical cause) who does not use one of the following contraceptive methods considered highly effective : intrauterine device, oestroprogestonic contraception or progestogen hormonal contraception associated with inhibition of ovulation, intrauterine hormone-releasing system, or bilateral tubal occlusion.
  • Control group
  • Age\> 18 years
  • +4 more criteria
