Abstract:

The residual effects of storm conditions at sea upon postural equilibrium functioning have not been studied objectively. As part of a larger study, the opportunity was taken to investigate by means of a new quantitative ataxia test battery differences between vestibular normals N20 and labyrinthine defective L-D human subjects N9. Following a highly stressful sea experience, during which bizarre stimulation of the vestibular apparatus was amply provided, the L-D group maintained or improved their baseline postural equilibrium test performance scores. The ten initially poorest scoring normals as a sub-group were found free of postural decrement in contrast with significant performance decrements observed in the initially highest scoring sub-group of normals. Probable influences over differential results within the normals and between groups as well as differential test findings are discussed.
