Theta-Burst-Stimulation in Recurrent Stroke Recovery

25 de novembro de 2019 atualizado por: Christian Grefkes, University Hospital of Cologne
The present study aims at investigating the effects of intermittent theta-burst stimulation (iTBS) for motor recovery in recurrent stroke patients. Therefore a daily intervention of repetitive transcranial magnetic stimulation over 8 days combined with subsequent physiotherapy is compared to a control condition, sham stimulation combined with subsequent physiotherapy. Motor function, degree of disability and quality of life are examined in order to evaluate the effects of iTBS in the rehabilitation of recurrent stroke patients in the first weeks and after three months.

Visão geral do estudo

Descrição detalhada

To date, the majority of neuromodulation approaches aiming at improving motor recovery after stroke are limited to patients with first-ever ischemic stroke. Therefore, rehabilitation of recurrent stroke mainly includes physiotherapy and occupational therapy. Yet, particular these patients retain movement impairment relevant for activities of daily living.

By using repetitive transcranial magnetic stimulation (rTMS), it is possible to promote recovery of connectivity between brain regions, particularly after stroke and thereby improve motor performance. Previous data indicate that intermittent theta-burst stimulation (iTBS), a protocol of neuromodulation, enhances the effects of subsequent motor training in early rehabilitation after stroke.

The current study aims at investigating whether daily repetitive transcranial magnetic stimulation over 8 days combined with subsequent physiotherapy leads to better motor recovery in recurrent stroke, compared to control condition, physiotherapy after sham stimulation. Motor function, degree of disability and quality of life are examined in order to evaluate the effects of iTBS in the rehabilitation of recurrent stroke patients in the first weeks and after three months.

Fugl-Meyer Motor Scale of the upper extremity, FM The Fugl-Meyer Assessment scale is an ordinal scale that has 3 points for each item. A zero score is given for the item if the subject cannot do the task. A score of 1 is given when the task is performed partially and a score of 2 is given when the task is performed fully.

Minimum score in upper limb = 0 Maximum score in upper limb = 66, Subscales are summed

After 8 days of intervention, and 3 months of enrollment
Stroke severity
Prazo: After 8 days of intervention, and 3 months of enrollment

National Instituts of Health Stroke Scale, NIHSS The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment.

The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0.

After 8 days of intervention, and 3 months of enrollment
Degree of disability
Prazo: After 8 days of intervention, and 3 months of enrollment
Modified Rankin Scale, mRS The scale runs from 0-6, running from perfect health (0) without symptoms to death (6).

Ipsilateral silent period The ipsilateral silent period (iSP) is supposed to be a specific marker of transcallosal motor inhibition. Measured by a short attenuation or interruption of ongoing voluntary electromyographic (EMG) activity in hand muscles induced by focal TMS of the ipsilateral M1.
