Video parameters for action observation training in stroke rehabilitation: a scoping review.

Most video parameters except for length and perspective of view remain underreported in AOT protocols. Future studies with better descriptions of video parameters are required for comprehensive AOT interventions and result generalisation.IMPLICATIONS FOR REHABILITATIONVideos shorter than 5 min may be preferred during action observation training (AOT) intervention in post-stroke.Egocentric view may be better for upper limb dexterity function and allocentric view for gross actions like walking.Choice of video disseminating device depends on its dimension as well as observer distance.Movement speed, video sound, and quality must be considered to obtain more comprehensive AOT videos.
