No. of nerves

Clinical condition

8

All claimed normal

Single peak likely to represent normalcy

(Plateau)

2

With single peak of DFL on opposite side

Cases with CS on one side are more likely to develop CS on the opposite side as well. Broad peak (plateau) may be an early indicator of CS.

As above

5

With double peak of DFL on opposite side, 4 with diagnosed CS, one with Pain in shoulder
