othyroidism, prompting the development of various assessment tools. Nerve conduction studies are among these tools. This study aimed to compare nerve conduction studies between patients with hypothyroidism and healthy volunteers. Materials and Methods: This study included 54 patients with hypothyroidism (cases) and 54 healthy volunteers (controls). Motor and sensory nerve conduction studies were performed bilaterally on the median and ulnar nerves in the upper limbs. Motor nerve conduction studies involved assessing distal motor latencies, motor nerve conduction velocity (NCV), and compound muscle action potentials' amplitude. Sensory nerve conduction studies included determining sensory NCV and amplitude of sensory nerve action potentials. Results: The average age of patients with hypothyroidism was 40.46 ± 6.21 years, while volunteers' average age was 38.16 ± 3.35 years. Independent Student’s t-tests revealed
