Objective: to "develop and evaluate the feasibility and reliability" of a measure for separating and quantifying the movements children make during VR therapy. The Movement Rating Instrument for Virtual Reality Video Game Play (MRI-VRGP) was applied to IREX and Kinect game systems.

Process: Movements were parsed into items and after several iterations, the selected items were trialled. Reviewers watched videotapes of subjects to rate upper extremity movements (unilateral or bilateral; close or far) and lower extremity movements within or without the base of support. They rated the activities as movements on a spectrum of easy to difficult and rated their confidence in making the rating.

Outcome: Within-rater reliability was higher (good) than inter-rater reliability (moderate). Finer movements were harder to rate consistently within therapists. Inter-rater reliability varied widely, and upper extremity fine (close) movements were rated less consistently.
More "item definition clarification and further psychometric property evaluation" will allow therapists to sort VR games by the type and frequency of their body movements.

Objective: For children with acquired brain injury, is a program of web-based and home-delivered rehabilitation better than the wait list treatment for occupational performance and upper limb measures?

Procedure: 58 9 – 14 year old children were matched using their age, Manual Abilities Classification Scale, full-scale IQ and other demographic and physical characteristics. The intervention group was encouraged to use the Mitii game system 30 minutes daily, 6 days per week for 20 weeks. The control group was wait-listed to receive the intervention. Mitii is based on Microsoft Kinect and comprises visual-perceptual, cognitive, upper limb and gross motor activities, accessed by internet.

Findings: Game play averaged less than an hour per week, substantially less than the recommended 3 hours weekly. “A home-delivered, multi-modal web-based rehabilitation programme did not achieve the anticipated dose of therapy for children with acquired brain injury… Results highlight issues around feasibility and acceptability of a… home-delivered intervention.”
