Fig 1 The ratio between maximum soleus H-reflex and M-wave amplitudes (H/M) before (pre-ITB) and at about 5 hours after ITB bolus injection (post-ITB) for more and less involved sides in 30 subjects with acquired brain injury. Two vertical lines define lower and upper limits of 99% confidence interval for H/M ratio (60%–74%) obtained in 30 young healthy subjects. Note that in the majority of subjects the H/M ratio substantially decreased after the injection.

Fig 2 The number of F waves recorded from 48 trials (F-wave persistence) in abductor hallucis muscle on the more involved side before (pre-ITB) and about 5 hours after ITB bolus injection (post-ITB). Note that F-wave persistence decreased in most subjects, but in 6 it clearly increased (broken line).
