A representative summary of the percent of total swallows (%) for each phase of respiration (1–4) in the subjects with SCI (n = 16) vs. able-bodied (n = 13) subjects. ╪Number of swallows is significantly higher for the phase 4 (late expiratory phase; P < 0.05), but no significant difference is noted between the subjects with SCI and able-bodied subjects. The statistical test used is two-way repeated measures ANOVA (F = 15.7, P < 0.05 for respiratory cycle phase factor). All representative data are mean ± SE. 1, beginning of inspiration to peak of inspiration; 2,  peak of inspiration to end of inspiration; 3, beginning of expiration to peak of expiration; 4, peak of expiration to end of expiration; SCI, spinal cord injury.
