摘      要：To the Editor:Contact heat evoked potentials(CHEPs)has become an important electrophysiologic diagnostic approach for small fiber neuropathy,[1]which is characterized by involvement of myelinated Aδand unmyelinated C fibers as a result of various etiologies.[1,2]CHEPs are affected by gender,age,body height,and so on.[1,2]The effect of the second to fourth(2D:4D)digit ratio on CHEP parameters has not been investigated.Digit ratio is defined as the length of the index finger dividing the length of the ring finger,which is smaller in men than in women.[3]We aimed to find out whether digit ratio has any role influencing CHEPs,and to strengthen the understanding and improve the methodology of CHEPs.
