Motor Nerve Conduction Studies in Newly Diagnosed Subclinical Hypothyroidism Patients

AIM& OBJECTIVE- Present study was aimed to assess involvement of peripheral nervous system in newly diagnosed& untreated sub-clinical hypothyroidism patients. METHOD- The present study included subjects aged 18-65 yrs (60 cases of biochemically diagnosed subclinical hypothyroidism& 60 healthy age matched controls). Motor nerve conduction parameters i. e. distal latencies (DL), compound muscle action potential (CMAP)& motor nerve conduction velocities (MNCV) were recorded bilaterally in median& ulnar nerves using standard protocols& settings. RESULTS- The study showed significantly prolonged distal latencies (DL), reduced compound muscle action potential (CMAP) Amplitude& decreased motor nerve conduction velocity (MNCV) in median& ulnar nerves.
