(A) Surface electromyogram findings. During the Achilles tendon reflex, tibialis anterior and gastrocnemius muscles exhibited continuous simultaneous co-contraction. The arrow indicates tapping of the Achilles tendon. (B) Blink reflex findings. (a) Record obtained on stimulation of the left side. (b) Record obtained on stimulation of the right side. In both (a,b), higher amplitude responses of R1 and R2 were observed from the left eyelid.

This is suggestive of rigidity in both the agonist and antagonist muscles of the Achilles tendon reflex (Figure 1A). Both the R1 and R2 components of the blink reflex showed higher amplitude on the left compared with the right after stimulation of either side, indicating hyper-excitability on the left side (Figure 1B).
A graphical summary of symptom onset and clinical management for the current case. The arrow on the left indicates the date of admission and the arrow on the right indicates the date of transfer.
