  • Values are mean (SEM).

  • 1-1 Number in group = 14.

  • 1-2 Number in group = 10.

  • Breathing rhythms: mean (SEM) per cent of monitored time spent in each rhythm.

  • Tone type: Number of subjects with hypo(tonia), normal tone, hyper(tonia), and dys(tonia) given.

  • Reported epilepsy: Number in group with reports of epilepsy

  • Pre/now walking solo: Number of subjects who had walked pre-regression/number of subjects who walked unaided at time of investigation.

  • CSB, mean sensitivity to baroreflex; CVT, mean cardiac vagal tone.
