Biologic Mechanisms of Early Exercise After Intracerebral Hemorrhage

Cerebrospinal fluid (CSF) will be collected only in patients with an external ventricular drain as part of patients' care.

An average of three hand-held dynamometry measurements will be calculated for each measurement episode and the change over time will be measured. Grip strength is reported in pounds and compared against population and sex-based normative values.

The global physical health status subscale of the Promis scale v1.2 will be used to measure pre-morbid physical health status. A 5-point Likert scale is used to score each of the four items. The scores for each item are summed as a raw score and are converted to T scores using a standardized table with higher T scores indicating better physical health status. An average t score representing the population is 50. 10 points is equal to 1 standard deviation, thus a score of 60 means that one is one standard deviation better than the general population.

The global mental health status subscale of the Promis scale will be used to measure pre-morbid mental health status. A 5-point Likert scale is used to score each of the four items. The scores for each item are summed as a raw score and are converted to T scores using a standardized table with higher T scores indicating better physical health status. An average t score representing the population is 50. Ten points is equal to 1 standard deviation, thus a score of 60 means that one is one standard deviation better than the general population.

The modified Rankin score will be used to measure function in terms of activities of daily living after stroke. A six-point ordinal scale (0-6) with lower scores indicating less disability and higher scores indicating increasingly severe disability. A score of 6 indicates death. Reporting the frequency of each score category.

The modified Rankin score will be used to measure function in terms of activities of daily living after stroke. A six-point ordinal scale (0-6) with lower scores indicating less disability and higher scores indicating increasingly severe disability. A score of 6 indicates death. Change in functional status was calculated by subtracting the first score (discharge) from the second score (90 day assessment).

The MRCS will be used to measure muscle strength over time. The instrument is a 60 point scale indicating muscle strength in 6 muscle groups. Three muscle groups each on the right and left upper extremities and three each in the right and left lower extremities. Each muscle group is scored from 0-5 out of a possible 5 points. A composite score with a maximum of 60 is produced, 30 points can be achieved for each side of the body.

The Barthel index will be used to measure a participant's ability to perform activities of daily living in detail. The instrument is a 10-item scale with a range of 0 -100 points. Higher scores indicate higher levels of function.

This is a 59-item questionnaire that will measure health status in 8 domains following the stroke. A 5-point Likert scale is used to score each item with higher scores indicating higher perceived health status.

The last question of the instrument measures a participant's perception of stroke recovery using a 0-100 scale with higher scores representing higher levels of recovery and lower scores representing less recovery.
