ContraStim: Contrastim Stroke Trial
Study Details
Study Description
Brief Summary
This is a prospective randomized controlled feasibility study to determine whether navigation guided repetitive transcranial magnetic stimulation (rTMS) to the healthy hemisphere in patients with subacute stroke has a beneficial effect when given concurrently with task-oriented motor rehabilitation of the arm and hand. Navigation guided rTMS requires a structural MRI scan for targeting stimulation and therefore structural MRI will be performed on all subjects. In addition the study intends to determine whether measures of motor tract integrity (MTI) assessed by navigated brain stimulation (NBS) and MRI diffusion tensor imaging can be used to clarify prognosis of motor recovery and to monitor progress with rehabilitation. 30 subjects with ischemic or hemorrhagic stroke 3-9 months prior to enrollment and with residual upper limb hemiplegia will be randomized to receive either 1 Hz rTMS to the contralesional hemisphere for 30 minutes 3 times a week for 6 weeks along with rehabilitation therapy or sham rTMS to the contralesional hemisphere for 30 minutes 3 times a week for 6 weeks along with rehabilitation therapy. Primary outcome is improvement on the Action Research Arm Test, a measure of arm and hand function in people with stroke. Outcomes will be measured immediately post treatment, and at 3 months and 6 months post treatment.

Detailed Description
PRIMARY OBJECTIVES To determine whether NBS guided 1Hz rTMS targeting the motor representation areas of hand muscles on the healthy brain hemisphere has a beneficial effect on the motor recovery of the corresponding stroke-affected muscles when combined with standardized task-oriented motor rehabilitation.
SECONDARY OBJECTIVES
-
To determine whether motor evoked potentials (MEPs) can be elicited from paretic and/or plegic muscles in patients with stroke using navigated TMS (eXimia NBS) and targeting the anatomical cortical areas representing the affected muscles.
-
To determine the correlation between existing MEPs, other TMS parameters and the clinical deficits of limb function.
-
To determine the prognostic value of MEPs and other TMS parameters in predicting motor recovery after stroke
-
To determine the diagnostic value of MEPs and other TMS parameters in monitoring the response to rehabilitation
-
To assess safety by capturing all Serious Adverse Events during both single pulse and rTMS delivery
STUDY PROCEDURES
The purpose of the study including risks and benefits will be explained to potential participants who will then be asked to sign an informed consent form. Potential participants will be screened for inclusion and exclusion criteria
The study will be performed in 2 parts. In part 1 Nexstim eXimia NBS will be utilized for neuronavigation and a third party TMS will be used for delivering the rTMS. In part 2 Nexstim eXimia NBS will be utilized together with Nexstim eXimia TMS for delivering the rTMS. Part 2 will commence once the patients participating in Part 1 have undergone the study visit 22 (see 5.1 below).
15 patients will be recruited to part 1 and 15 patients for part 2 (6 additional subjects will be recruited assuming a 20% drop out rate)
In part 1 of the study 10 subjects will be randomized to rTMS treatment and 5 subjects will be randomized to sham rTMS. Of the 10 rTMS treatment subjects, 5 will be given stimulation protocol A and 5 will be given stimulation protocol B, described below. In part 2, either stimulation protocol A or B will be chosen for continue study based on predetermined outcome criteria. In part 2, 10 subjects will receive this chosen rTMS treatment and 5 subjects will receive sham rTMS.
The study will consist of 24 study visits with the addition of 4 additional visits as needed to complete outcome assessments.
VISIT SCHEDULE
The study will be performed over 24 to 28 sessions:
-
Visit 1(Screening visit): Baseline = 3-9 months after the stroke. The purpose of this visit is to obtain informed consent for the study (if not previously obtained) and to screen subjects for inclusion and exclusion criteria.
-
Visit 2: Baseline assessment. The purpose of this visit is to establish the baseline of injury, motor status and NBS parameters (Hand motor mapping and motor tract integrity, both hemispheres - see appendix A). Subjects will also undergo a structural MRI. The subject will then be randomized to either rTMS or to sham treatment. The baseline visit may if necessary take place on 2 separate days.
-
Visits 3-21: During these visits the patient will undergo standardized task-oriented motor rehabilitation of the hand. In addition the patient will receive the rTMS therapy according to the protocol of the group she/he was randomized into during visit 1. The visits will take place during a 6 week period, three visits per week. During each week the visits will take place each on a separate day and a maximum of two visits will take place on consecutive days. During the first visit of each week (visits 3, 6, 9, 12, 15 and 18) in addition to the rTMS and task-oriented motor rehabilitation, the patient will undergo measurement of NBS parameters (Motor tract integrity, both hemispheres).
-
Visit 22: End of the task-oriented motor rehabilitation. The purpose of the visit is to establish the extent of recovery that has occurred during the rehabilitation. The visit will take place 3-5 days after the last rTMS/rehabilitation session and includes functional motor testing and evaluation of NBS parameters (Hand motor mapping and motor tract integrity, both hemispheres). 1-2 visits may be needed to complete assessment.
-
Visit 23: 1 month after the end of the rehabilitation therapy. The purpose of the visit is to determine whether any changes in motor function or NBS parameters have occurred within 1 month of ending therapy. The assessment includes functional motor testing and evaluation of NBS parameters (Hand motor mapping and motor tract integrity, both hemispheres). 1-2 visits may be needed to complete assessment.
-
Visit 24: 6 months after end of the rehabilitation therapy. The purpose of this visit is to determine the long-term rehabilitation success. The assessment includes functional motor testing and evaluation of NBS parameters (Hand motor mapping and motor tract integrity, both hemispheres. In patients experience a new stroke or TIA during this time, only the data prior to the event will be used in the analysis. 1-2 visits may be needed to complete assessment.

Outcome Measures
Primary Outcome Measures
- Upper Extremity Fugl-Meyer Score [Baseline, post treatment, 1 month, 6 months]
Upper extremity Fugl-Meyer Score measures of motor impairment in hemiplegic upper limb of patients with stroke. The scoring follows the natural progression of motor recovery as defined by Twitchell (Brain. 1951; 64:443-480). The score was developed by Axel Fugl-Meyer and it has been validated (Scand J Rehab Med. 1975; 7:13-31; Stroke. 2009; 40: 1386-1391). The scale ranges 0-66 with 66 representing normal motor function and 0 representing no movement. There are 33 movement items each scored 0 (cannot perform), 1 (peforms partially), 2 (performs flawlessly)
Secondary Outcome Measures
- Action Research Arm Test [Baseline, post treatment, 1 month, 6 months]
The ARAT is a measure of upper limb dexterity and is a 19 item measure divided into 4 sub-tests (grasp, grip, pinch, and gross arm movement). Performance on each item is rated on a 4-point ordinal scale ranging from: 3: Performs test normally 2: Completes test, but takes abnormally long or has great difficulty 1: Performs test partially 0: Can perform no part of test Range is 0-57 with higher scores relating to better upper limb dexterity
- Stroke Impact Scale [Baseline, post treatment, 1 month, 6 months]
The SIS is a quality of life questionnaire designed for stroke survivors. It is a 59 item measure 8 domains assessed: Strength (4 items) Hand function (5 items) ADL/IADL (10 items) Mobility (9 items) Communication (7 items) Emotion (9 items) Memory and thinking (7 items) Participation/Role function (8 items) Each item is rated in a 5-point Likert scale in terms of the difficulty the patient has experienced in completing each item Summative scores are generated for each domain, scores range from 0-100
- Chedoke Arm Assessment [Screening, baseline, weekly, post treatment, 1 month, 6 months]
A 7 point scale of motor recovery scored separately for arm. 7 is good motor recovery and 1 is no movement.
