Peripheral neuropathies are a group of disorders that affect the peripheral nervous system, for which hundreds of etiologies have been identified. This article presents a stepwise approach to the evaluation and workup of peripheral neuropathy, which starts with a detailed history of symptoms, family and occupational history, and a neurological as well as general physical exam. Pattern recognition of various neuropathies can help to build a differential diagnosis based on the presentation. Such patterns include acute versus chronic, primary demyelinating versus axonal, hereditary versus acquired, asymmetric versus symmetric, presence of facial palsies, sensory or motor predominant, and presence of prominent autonomic symptoms. Early categorization of the type of neuropathy can help focus the workup for peripheral neuropathy. Nerve conduction studies and electromyography (NCS/EMG) is the primary diagnostic tool in the evaluation of patients with large-fiber polyneuropathy. One of the most important roles of NCS/EMG is to help categorize polyneuropathy as primary axonal versus primary demyelinating. The finding of a primary demyelinating polyneuropathy narrows the differential diagnosis of polyneuropathy dramatically and increases the chances of finding a treatable etiology. Laboratory workup includes serum studies and potentially cerebrospinal fluid, genetic studies, immunological markers, and fat pad biopsy for select patients. Skin biopsy may be used to assess intraepidermal nerve fiber density if small-fiber neuropathy is suspected, and nerve biopsy may be useful in select cases. In recent years, magnetic resonance imaging and neuromuscular ultrasound have also shown promise in the evaluation of peripheral neuropathy. Identification of the etiology of neuropathy is crucial and often time-sensitive, as an increasing number of causes are now reversible or treatable.

Lateral femoral cutaneous neuropathy is a focal neuropathy caused by compression of the lateral femoral cutaneous nerve (LFCN) at the level of anterior-superior iliac spine or inguinal ligament. It is commonly associated with diabetes mellitus, obesity, and wearing tight clothing. 1 It can

BACKGROUND: The coronavirus disease-2019 pandemic led to rapid expansion of telehealth services. This was speculated to improve healthcare access among underserved populations, including individuals unable to take time off work or arrange transportation. OBJECTIVE: We completed a quality improvement project to evaluate the feasibility of hybrid consultations that combined televisits and abbreviated in-person visits for neuromuscular referrals. METHODS: Using a censoring date of August 5, 2021, we reviewed all outpatient neuromuscular consultations from August 5, 2020 to February 5, 2021. For both hybrid and traditional in-person consultations, we reviewed no-show rates, completion rates of ordered diagnostic workup, and billing codes. For hybrid consultations only, we also reviewed intervals between initial televisit and subsequent examination and rates of video-enhanced versus audio-only televisits. RESULTS: During the study period, we completed 153 hybrid and 59 in-person new-patient consultations (no-show rates 9% and 27% respectively.) For hybrid consultations, 77% and 73% of laboratory and imaging studies were completed respectively, compared to 89% and 91% for in-person consultations. For hybrid visits, average RVUs (a marker for reimbursement) per consultation depended on whether audio-only televisits were billed as telephone calls or E/M visits per insurance payer rules, while video-enhanced televisits were uniformly billed as E/M visits. This resulted in average RVUs between 2.09 and 2.26, compared to 2.30 for in-person consultations. CONCLUSIONS: Telehealth-based hybrid neuromuscular consultations are feasible with minor caveats. However, the future of telehealth may be restricted by decreasing reimbursement rates particularly for audio-only televisits, limiting its potential to improve healthcare access.
