Intra-session test-retest reliability of magnitude and structure of center of pressure from the Nintendo Wii Balance Board™ for a visually impaired and normally sighted population

Highlights • Reliability of the Wii Balance Board was evaluated for blind and normally sighted. • Center of pressure and Approximate Entropy had moderate to very high reliability. • COP scores increased with the difficulty of condition indicating WBB sensitivity. • Absolute reliability was comparable across groups. • The Wii Balance Board was found to be a practical tool for screening balance.
