Background: the seat of the kayaker represent the principal contact point to express mechanical Energy.
Methods: therefore we investigated the reliability of the Wii Balance Board measures in the kayak vs. on the ground.
Results: Bland-Altman test showed a low systematic bias on the ground (2.85%) and in kayak (-2.13%) respectively; while 0.996 for Intra-class correlation coefficient.
Conclusion: the Wii Balance Board is useful to assess postural sway in kayak.
