From: What do randomized controlled trials say about virtual rehabilitation in stroke? A systematic literature review and meta-analysis of upper-limb and cognitive outcomes

Moderator Type

Definition

Design factors

 Intervention Type

Virtual Environment (VE) design or Computerized Gaming (CG) system

 Simulation Type

Intervention targeting hand/finger function or interventions targeting overall upper-limb function

 Study Quality

 Recovery Stage

Sub-Acute (≤3 months post-stroke) or Chronic (>  3 months post-stroke)

 Control Group Type

Passive (treatment as usual) or Active (treatment as usual + additional rehabilitation) comparison control group

Implementation Parameters

 Duration
