IMAS Optimization and Applicability in an Acute Stroke Setting.

Study Overview
=================
Brief Summary
-----------------
The investigator will investigate our Integrated sensor-based Motion Analysis Suite (IMAS) to objectively and quantitatively measure acute stroke patient motor status.

Detailed Description
-----------------
The investigator will evaluate the feasibility of our IMAS to assess 30 stroke subjects in 5 sessions (the first 4 proximal to stroke onset and the last session  6-8 weeks post stroke). The investigator will test IMAS in 30 acute stroke subjects; and extract quantitative movement kinematic/kinetic metrics descriptive of subjects' motor behavior (e.g., arm movement speed, smoothness). Subjects will undergo a series of upper limb focused assessments including Fugl Meyer, Barthel Index, and Orpington Prognostic Scale assessments. The investigator will also collect demographics, and stroke clinical information such as imaging data.

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Providing informed consent to participate in the study. Age 18 to 85 years old. Clinical presentation and neuroimaging (CTA-CTP/ MRI-MRA) consistent with the diagnosis of Acute Ischemic or Hemorrhagic Stroke. Preserved mental status (Glasgow coma score >12: E(4), V(5), M (4-6)). Presence of upper limb weakness per the NIHSS (1-2 points in the arm) and ability to perform testing (i.e. NIHSS motor score 1-2 at elbow, wrist, and finger flexion extension). (Note that individuals with a prior ischemic or hemorrhagic stroke with available information pertaining superior extremity baseline strength after their previous stroke would qualify). Baseline Modified Rankin score <4. Exclusion Criteria: History of alcohol or drug abuse within the past 6 months as self-reported; History of schizophrenia, schizoaffective disorder, other psychosis, bipolar illness, alcohol/drug abuse within the past year; Need for rapid clinical response due to conditions such as initiation, psychosis, or suicidality; Unstable medical conditions (e.g. uncontrolled diabetes, uncompensated cardiac issues, heart failure, pulmonary issues, or chronic obstructive pulmonary disease); History of dementia per relative/ medical records. Presence of receptive aphasia at baseline or after the current acute stroke. Amputated limbs. Absence of weakness as per the NIHSS (0 points = no drift for motor arm and leg items) or severe motor impairment NIHSS 4 points for motor arm). Stroke mimics (e.g., infections, medication effects from sedatives, electrolyte imbalances, etc.). Stroke worsening between assessments.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Biomechanical Assessments of movements from the Fuegl-Meyer Scale. Prediction of motor recovery post-stroke. | The sensor suite will assess patient movement from the Fuegl-Meyer Scale through kinetics (e.g., time to perform the movement (seconds), position, distance (mm), velocity mm/sec), and kinematics (e.g., angular velocity (mm/sec). | 6 - 8 weeks post acute stroke onset | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Barthel Index | The Barthel Index questionnaire measures the extent to which somebody can function independently and has mobility in their activities of daily living (ADL) i.e. feeding, bathing, grooming, dressing, bowel control, bladder control, toileting, chair transfer, ambulation and stair climbing. | 6 - 8 weeks post acute stroke onset. |
