Introduction: Rheumatoid Arthritis (RA) is a chronic multisystem immune mediated disease. Rheumatoid associated neuropathy causes significant disability and adds to the economic burden. Aim: To assess clinical determinants of peripheral neuropathy (diagnosed electrophysiologically using nerve conduction studies) among patients with RA. Additionally, it was also aimed to study the various patterns of peripheral neuropathy in patients with RA. Materials and Methods: A cross-sectional study was conducted on 100 consecutive adult patients with RA between 01stFebruary, 2020 to 02nd January, 2021 at medicine and neurology departments of SMS Medical College and Hospital, Jaipur, Rajasthan, India. Inclusion and exclusion criteria were followed and eligible patients after appropriate laboratory evaluation underwent nerve conduction studies. Statistical analysis was performed using student’s unpaired t-test and Chi-square test for continuous and categorical variables respectively. Results: Mean age of the study population was 42.4±14.2 years with 88 females and 12 males. Mean duration of RA was 7.0±7.4 years. Nerve conduction studies detected neuropathy in 18 patients, of these only four patients were symptomatic with tingling, pins and needles sensation and numbness. Fourteen patients had subclinical neuropathy. Patients with neuropathy had significantly longer disease duration (p=0.0001), were older (p=0.014) with more joint deformities (p=0.0008). Conclusion: Subclinical neuropathy is not infrequent in RA patients. Those with advanced age, longer disease duration, higher Erythrocyte Sedimentation Rate (ESR), erosions and deformities should be assessed electrophysiologically for neuropathy.

Background: Diagnosis of polyneuropathy is typically made using sensory and motor nerve conduction studies (NCS). These tests include measurement of amplitude, velocity, and delay of sensory and motor waves. These waves cannot assess the entire length of the nerve, proximal parts in special. F-wave is the only test capable of measuring the entire length of the nerve. The purpose of this study was to evaluate the value of F-wave in patients with diabetic polyneuropathy. Methods: This is a retrospective study assessing the value of nerve conduction studies and F-wave in the diagnosis of 148 patients with diabetic polyneuropathy referred to hospitals under the supervision of the University of Iowa from October 1, 2016, to September 5, 2018. Motor neurons of median, ulnar, peroneal, and tibial nerves and sensory neurons of median, ulnar, and sural nerves were assessed using two techniques of NCS and F-wave. Then the data were compared. Results: The results of this study showed that F-wave in all of the evaluated nerves (median, ulnar, tibial and peroneal) detected abnormalities to more extents than routine NCS (P <0.001). When total neuronal abnormalities were accumulated, this value was 82٪ for NCS, while 99٪ for the F wave (P < 0.001). Conclusion: Findings of the current study showed that the assessment of delayed nerve conducting through F-waves can diagnose diabetic polyneuropathy to better extents as compared to NCS. Further evaluations are recommended.

Background. Nerve conduction studies (NCS) are electrodiagnostic tests used to evaluate peripheral nerves functions and aid in the assessment of patients with neuromuscular complaints. There is contrasting evidence concerning the use of NCS in the assessment of patients with lumbosacral radiculopathy. Objectives. This study was conducted to evaluate nerve conduction studies abnormalities in patients with lumbosacral radiculopathy and to find out their relation to abnormal physical examination findings. Materials and Methods. Twenty-seven patients with lumbosacral radiculopathy caused by L4/5 or L5/S1 intervertebral disc prolapse confirmed by magnetic resonance imaging (MRI) were recruited in the study. Twenty-five healthy subjects matched in age and sex served as control. Motor nerve conduction study bilaterally for both common peroneal and tibial nerves, F-wave for both nerves, and H-reflex had been conducted. Results. No significant difference was found in the motor nerve conduction study parameters (latency, amplitude, and conduction velocity) between the patients group and the control group. There was significant prolongation in H-reflex latency of both symptomatic and asymptomatic side in the patients group compared to the control group ( P < 0.05 ). Also, F-wave latencies (F minimum, F maximum, and F mean) of the tibial nerve were significantly prolonged ( P < 0.05 ) compared to control. Conclusion. Prolonged H-reflex latency was the commonest encountered abnormality in our study followed by F-wave latencies of the tibial nerve.
