For the lower limbs, the Nintendo Wii Balance Board (NWBB) has been
widely used to measure postural control. However, this has not been performed for
upper limb measurements. Further, the NWBB has shown to produce more background
noise with decreasing loads, which may be of concern when used for upper limb
testing. The aim was to investigate reproducibility and validity of the NWBB.
METHODS: A test-retest design was performed with 68 subjects completing three
different prone lying, upper limb weight-bearing balance tasks on a NWBB:
two-arms, eyes closed (1) one-arm, non-dominant/non-injured (2) and one-arm,
dominant/injured (3). Each task was repeated three times over the course of two
test sessions with a 30-min break in between. Further, the level of background
noise from a NWBB was compared with a force platform through systematic loading
of both boards with increasing deadweights ranging from 5 to 90kg. RESULTS:
Test-retest reproducibility was high with ICCs ranging from 0.95 to 0.97 (95% CI
0.92 to 0.98). However, systematic bias and tendencies for funnel effects in the
Bland Altman plots for both one-armed tests were present. The concurrent validity
of the NWBB was low (CCC 0.17 (95% CI 0.12-0.22)) due to large differences
between the NWBB and force platform in noise sensitivity at low deadweights
(especially below 50kg). CONCLUSION: The NWBB prone lying, shoulder sensorimotor
control test was highly reproducible. Though, concurrent validity of the NWBB was
poor compared to a force platform. Further investigation of the impact of the
background noise, especially at low loads, is needed.
