  1. Table 2, Quantitative and qualitative gait characteristics for all four groups expressed as means and standard deviations. Abbreviations: WB is walking bouts, Freq. Variability is the stride frequency variability, IH is the Index of Harmonicity, Amplitude (psd) is the amplitude of the dominant peak in the power spectral density, Width (psd) is the width of the dominant peak in the power spectral density, LDE/stride is the local divergence exponent per stride. VT is the vertical direction, ML is the medio-lateral direction and AP is the anterior-posterior direction. Significant associations derived from logic regression (Table 3) are printed in bold
