Stimulus induced after discharges seen during tibial F wave study

(A) Tibial F wave study showing normal F waves. The solid horizontal line denotes normal F wave duration in the superimposed waves (settings gain 200 microvolt/division, time base 20 ms/division). (B) Tibial F wave study showing stimulus induced after discharges with F waves being obscured. The solid horizontal line denotes stimulus induced after discharge duration of 140 ms (settings gain 200 microvolt/division, time base 20 ms/division).
