Outcome measures
Primary outcome
Main study parameters are related to (timing of) gaze behaviour during several
reaching and object manipulation tasks such as proportions of task duration
with gaze focused on task-relevant objects (TRO gaze), on task-relevant body
parts (TRB gaze), and on task-irrelevant objects (TIO gaze) (expressed in
percentages of total task duration).
Secondary outcome
To explore whether, and how, visuomotor behaviour of stroke survivors differs
from healthy controls
To explore whether, and how, visuomotor behaviour of stroke survivors differs
between participants with left- and right hemisphere strokes
Background summary
Upper limb weakness or hemiparesis is one of the foremost causes of disability
after stroke. Since upper limb function is essential to perform activities of
daily life (ADL) independently, assistive technologies are designed to help
people recover physical interaction with their environment. For such devices to
be applicable in ADL, their control needs to be highly intuitive and user
friendly. A promising way for such intuitive control is intention detection
based on gaze. Next to upper limb weakness, sensory impairments and unilateral
spatial neglect are also common in the stroke population, which are likely to
affect gaze behaviour. However, gaze behaviour of stroke survivors during
active execution of upper extremity movements in 3D situations (i.e., real-life
tasks with actual objects) is currently unknown.
Study objective
The primary objective is to gain insight into gaze behaviour of stroke
survivors during upper extremity movements.
Study design
The current study is an observational study with one measurement session per
participant
Study burden and risks
The risks for the subjects are limited to a minimum. All tasks performed during
the study will consist of arm movements that normally occur in ADL, while being
seated, and will be performed within the abilities of each individual. All
measurements take place in a controlled environment at a lab of Roessingh
Research and Development with a researcher present. The researcher carefully
monitors the participants during the measurements. Recordings of gaze behaviour
are performed using a lightweight, wearable system (like glasses) equipped with
camera*s and head movement trackers, without obstructing the person*s (head)
movements.

* Sufficient cognitive status to understand two-step instructions
* Provide written informed consent
Exclusion criteria
A potential subject who meets any of the following criteria will be excluded from participation in this study:
