COgnitive-somatoSensory-MOtor Training to Improve Arm and Hand Function After Stroke (iCOSMO)

Measures of fidelity will monitor intervention delivery such as the number of intervention sessions attended and the amount of practice.

The Kinarm standard tasks™ will include the Reverse Visually Guided Reaching. The Reverse Visually Guided Reaching task assesses attention, inhibitory control and cognitive control of visuomotor skills. A task score will be reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Trail Making A&B. The Trail Making tests evaluate task switching abilities. There are 2 parts of this test. Trail A: trace a sequence of targets numbered 1 to 25; Trail B: Trace alternating numeric-alpha sequence of targets 1-A-2-B etc. A task score will be reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Object Hit and Avoid. The Object Hit and Avoid task assesses spatial attention, rapid motor selection and inhibition control. A task score will be reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Spatial Span Task. The Spatial Span test evaluates visuospatial working memory. A task score will be reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Paired Associates Learning. The Paired Associates Learning task evaluates visuospatial working memory by testing the ability to associate patterns with spatial locations and recall them after a delay. A task score will be reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Visually Guided Reaching. The Visually Guided Reaching task measures the subject's visuomotor capabilities and multi-joint coordination. A task score will reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Object Hit. The Object Hit task is a rapid sensorimotor decision and control test. A task score will be reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Ball-on-Bar. The Ball on Bar task assesses bimanual coordination and visuomotor skills. A task score will reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Arm Posture Perturbation. The Arm Posture Perturbation task assesses the responsiveness to unexpected disturbances to the arm. A task score will reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Arm Positioning Matching: The Arm Position Matching task measures of a subject's proprioceptive capabilities in the upper limb. A task score will be reported as a measure of a participant's performance against healthy populations.

The Kinarm standard tasks™ will include the Arm Movement Matching: The Arm Movement Matching task assesses the ability of a subject to perceive limb motion or kinesthesia in a workspace. A task score will be reported as a measure of a participant's performance against healthy populations.

FMA-UE provides quantitative measures of sensory and motor impairments in the upper limbs and is scored from 0-66.

The ARAT assesses motor performance of the upper limb. It consists of 19 tasks across the 4 subscales (grasp, grip, pinch, gross movement).

Maximum voluntary grip strength with the Jamar dynamometer will be used as a conventional measure of muscle strength in the upper limb post-stroke.

Pulp-to-pulp pinch strength will be assessed using a pinch gauge (B & L Engineering).

The BBT will be used to assess gross manual dexterity.

The SFVAS, a single-item scale with a rating of 1 (no fatigue) to 10 (severe fatigue), will be used to assess the presence and extent of mental and physical fatigue.

PVAS is a single-item scale ranging from 0 (no pain) to 10 (excruciating pain).
