Critical Periods After Stroke Study (CPASS)

Status unconfirmed · Not applicable

Conditions studied: Stroke, Brain Infarction, Brain Ischemia, Cerebral Infarction, Cerebrovascular Disorders

In brief

To perform an exploratory single center randomized study that will form the basis for a larger scale, more definitive randomized clinical trial to determine the optimal time after stroke for intensive motor training. The investigators will perform a prospective exploratory study of upper extremity (UE) motor training delivered at higher than usual intensity at three different time points after stroke: * early (initiated within 30 days) * subacute/outpatient (initiated within 2-3 months) * chronic (initiated within 6-9 months) The control group will not receive the therapy intervention during the 1-year study. Outcome measures will be assessed at baseline, pre-treatment, post-treatment, 6 months and one year after stroke onset. Compared to individuals randomized during the outpatient (2-3 months after stroke onset) or chronic (6-9 months after stroke onset) time points, participants randomized to early intensive motor training will show greater upper extremity motor improvement measured at one year post stroke.

Who can join

Age: 21 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Ischemic or hemorrhagic stroke (with confirmatory neuroimaging) within 28 days of admission to inpatient rehabilitation (allows those randomized to the early arm to begin study-related treatment within 30 days)
• Age >21 years
• Able to participate in first study-related treatment session within 30 days of stroke onset
• Able to participate in all study-related activities, including one year follow up and blood draws
• Persistent hemiparesis leading to impaired upper extremity function. Hemiparesis as indicated by NIHSS Motor Arm score ≥ 1
• Recovering moderate motor impairment at the shoulder and elbow or hand such as:
• Proximal UE voluntary activity indicated by a score of ≥ 3 on the upper arm item of the Motor Assessment Scale - wrist and finger movement is not required
• or
• Manual Muscle Test (MMT) score of ≥ 2 on shoulder flexion or abduction and MMT score of ≥ 2 for any of the following: elbow flexion, elbow extension, wrist flexion, wrist extension, finger flexion or finger extension.
• or
• Active range of motion (AROM) to at least 50% of range in gravity eliminated position for shoulder flexion or abduction, and for any of the following motions: elbow flexion, elbow extension, wrist flexion, wrist extension, finger flexion or finger extension.
• Score of ≤ 8 on the Short Blessed Memory Orientation and Concentration Scale
• Follows 2 step commands
• No upper extremity injury or conditions that limited use prior to the stroke
• Pre-stroke independence: Modified Rankin Score 0 or 1

You may not qualify if…

• Inability to give informed consent
• Prior stroke with persistent motor impairment or other disabling neurologic condition such as multiple sclerosis, parkinsonism, amyotrophic lateral sclerosis (ALS), dementia requiring medication
• Rapidly improving motor function
• Clinically significant fluctuations in mental status in the 72 hours prior to randomization
• Hemispatial neglect as determined by >3 errors on the Mesulam Symbol Cancellation Test
• Not independent prior to stroke (determined by scores of <95 on Barthel Index or >1 on Modified Rankin Scale
• Dense sensory loss indicated by a score of 2 on NIHSS sensory item
• Ataxia out of proportion to weakness in the affected arm as described by a score of ≥ 1 on the NIHSS limb ataxia item
• Active or prior psychosis within 2 years
• Active or prior (within 2 years) substance abuse
• Not expected to survive 1 year due to other illnesses (cardiac disease, malignancy, etc)
• Received upper extremity botulinum toxin within 6 months (other medications do not exclude)
