Universitätsklinikum Hamburg-Eppendorf
  Purpose
Testing the hypothesis that non-invasive brain stimulation by transcranial direct current stimulation (tDCS) combined with functional training in the subacute phase of first-ever stroke will enhance functional regeneration compared with a Placebo intervention.

Condition Intervention
Stroke Device: DC-Stimulator to apply tDCS Device: DC-Stimulator to apply Sham tDCS

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Neuroregeneration Enhanced by TDCS in Stroke

Further study details as provided by Universitätsklinikum Hamburg-Eppendorf:

Primary Outcome Measures:
  • Upper Extremity Fugl-Meyer-Assessment (UEFMA) [ Time Frame: 1 day after the end of the 2-weeks intervention ]
    standardized test of upper extremity function


Secondary Outcome Measures:
  • Upper Extremity Fugl-Meyer-Assessment (UEFMA) [ Time Frame: 30 days, 90 days, and 12 months after the intervention ]
    standardized test of upper extremity function

  • Action Research Arm Test (ARAT) [ Time Frame: 1 day, 30 days, 90 days, and 12 months after the intervention ]
    standardized tests of upper extremity function

  • Nine Hole Peg Test (NHPT) [ Time Frame: 1 day, 30 days, 90 days, and 12 months after the intervention ]
    standardized test to assess fine motor skills

  • Stroke Impact Scale (SIS) [ Time Frame: 1 day, 30 days, 90 days, and 12 months after the intervention ]
    questionnaire is to evaluate how stroke has impacted health and life of patients

Detailed Description:

Stroke is the leading cause of long-term disability, which significantly impairs the economic and social life of patients and society. Every year 200 000 to 250 000 patients suffer a stroke in Germany. Only a small number of the stroke survivors recover to a degree that allows them to return into their professional and private life. Despite significant efforts to develop novel and efficient treatment strategies the level of functional regeneration is still not satisfying. Thus, the development of innovative and effective treatment strategies will have a major impact for the patients' life, the society and the public health system.

Within the proposed project an innovative, non-invasive and cost effective interventional strategy, based on the combination of a specific rehabilitative training and brain stimulation by transcranial direct current stimulation (tDCS), will be used to enhance functional regeneration in stroke patients. The intervention will be applied in an early stage in which plasticity, cortical reorganization and functional improvement is most pronounced. We hypothesize that the combination of anodal tDCS delivered to the motor cortex of the affected hemisphere combined with training over a period of two weeks in the subacute stage after stroke will significantly enhance cortical plasticity, functional regeneration and long-term outcome determined by clinical and functional outcome measures compared with Placebo stimulation.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subacute stroke patients (5-45 days after stroke, age>18 years) with thromboembolic non-hemorrhagic subcortical or cortical, clinically overt first-ever strokes will be included. Moderate to moderately severe upper-extremity hemiparesis, defined as an Upper Extremity Fugl-Meyer score (UEFMA) between 20 and 58 (inclusive).

Exclusion Criteria:

  • pre-existing large lesions (> 1.5 cm maximum diameter in a brain area that belongs to the anatomically established sensorimotor/premotor system
  • progressive stroke
  • completely lesioned hand knob area of M1affected if no motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) are present
  • bilateral motoric impairment
  • florid alcohol and/or drug abuse
  • florid severe psychiatric illness (e.g. schizophrenia)
  • severe language disturbances that prevents the patient to give informed consent or inhibit adequate scoring because of insufficient understanding of scoring introductions
  • tumor diseases with a life expectancy less than one year
  • increased intracranial pressure
  • polyneuropathy and/or ischemic peripheral disease if the sensorimotor functions of the upper extremities are affected clinically relevant
  • severe cognitive deficits (MMSE ≤ 23)
  • pregnancy
  • contraindication for MRI or TMS
