The aim of this study is to monitor the daily upper limb movement of persons with stroke, and to relate these quantities to measures of recovery and impairment.
This study is part of The Natural History of Stroke Recovery project. In this study the investigators plan to develop, test and validate an algorithm and software for using Inertial Measuring Units (IMUs) to monitor upper limb daily movement. Then, investigators plan to use this system to monitor such activity in stroke patients.
Investigators also plan to develop, test and validate an algorithm and software to test proprioception acuity based on muscle synergy during active and passive movement. Muscle synergy will be determined based on muscles' electrical activity, as measured using surface electromyography (EMG).
Investigators will then test the relation between daily movements of the upper limb in stroke patients, and their recovery/impairment levels, including proprioception acuity.
7,286 studies on the registry are indexed under Stroke; 2,007 are open to participants now.
This study's planned enrollment of 40 is below the median of 160 across 1,692 observational studies indexed under Stroke.

Exclusion Criteria:
Persons after a stroke. See inclusion/exclusion.
Healthy persons. See inclusion/exclusion.
Hand movements-count
The number of hand movements (count)
Time frame: One or two occasions over 1-6 hours each.
Hand movements-duration
The total and average (per hour) time the hands moved, over the tested period. Measured in minutes.
Time frame: One or two occasions over 1-6 hours each.
Active joint range
Maximum, minimum, and mean range of motion of the joints during daily activity. Measured in degrees/radians.
Time frame: One or two occasions over 1-6 hours each.
Wrist distance
The maximum, average and total distance of the wrist from the body during movements. Measured in cm.
Time frame: One or two occasions over 1-6 hours each.
Fugl-Meyer Assessment (FMA)
Fugl-Meyer Assessment: Motor score of the upper limb is on a 0-66 scale. High score is better.
Time frame: One occasions during the first month following recruitment.
Action Research Arm Test (ARAT)
Action Research Arm Test Score is on a 0-57 scale. High score is better.
Time frame: One occasions during the first month following recruitment.
Proprioception-1
The difference between joint angles in an angle matching task. E.g., matching the shoulder angle of a passively moved arm with the contralateral arm. Angles include both anatomical angles and elevation angles. Measured in degrees/radians.
Time frame: One occasions during the first month following recruitment.
Proprioception-2
Parameters of the correlation (regression) between EMG signals during active and passive movement. Including the constant (in mV), slope (arbitrary units) and R\^2 (arbitrary units).
Time frame: One occasions during the first month following recruitment.
Proprioception-3
Delay between hand movement initiation observed kinematical (acceleration) and kinetically (EMG signal). Measured in msec.
Time frame: One occasions during the first month following recruitment.
Joint range of motion
Maximum and minimum joints range of motion (active and passive). Measured in degrees/radians.
Time frame: One or two occasions over 1-6 hours each.
Synergies
Parameters of the correlation (regression) between the kinematic signals of the different upper extremity segments. Including the slope (arbitrary units) and R\^2 (arbitrary units).
Time frame: One or two occasions over 1-6 hours each.
Angular velocity.
Maximum and average angular velocity of the joints during daily activity. Measured in degrees/radians per second
Time frame: One or two occasions over 1-6 hours each.
Movement volume
Volume occupied by the limb segments calculated using the 3D location of the joints. Measured in cm\^3.
Time frame: One or two occasions over 1-6 hours each.
Whole body movement time
The total and average (per hour) time of movements of the whole body. Measured in minutes.
Time frame: One or two occasions over 1-6 hours each.
Plan to share: Yes — All IPD that underlie results in a publication.
