  1. The characteristics of increased %change (Δ) in skin blood flow (SkBF) during local cooling (LC; 15 °C and 8 °C stage) in participants with cervical cord injury (SCIC) and thoracolumbar spinal cord injury (SCITL) are shown as the mean ± SD. Timeonset, a time to the onset of the increase in %ΔSkBF during each LC stage; Timepeak, time to peak from the Timeonset. Min, the lowest values before the onset of increased %ΔSkBF during each LC stage; Max, the maximum value during each LC stage; Amp, the amplitude calculated as Max–Min; Mean, the averaged value of each increased response after the onset; Increase in SkBF, number of participants in whom %ΔSkBF increased over 50% of Min. P values of ANOVA are shown in order of within factor (Temperature), factor of between participants (Group), and interaction of Temperature and Groups in SCIC and SCITL. †, #, compared between 15 °C vs 8 °C LC in SCIC and SCITL, respectively. Significance level is p < 0.05.
