Abstract

Purpose: As a first step towards developing a core outcome set (COS) for sciatic neuropathy, the goal of the current study was to perform a systematic review of the literature to identify outcome measures that have been previously reported in studies on sciatic neuropathy.

Methods: A systematic review of the literature from 2000-2024 was performed utilizing PubMed and Medical Subject Headings (MeSH). Identified articles were screened according to study inclusion/exclusion criteria. Outcome measures reported in each included study were recorded and categorized into motor, sensory, pain, patient-reported outcomes, electrodiagnostic outcomes, imaging outcomes, and composite outcomes. Descriptive statistics were performed.

Results: A total of 1586 articles were initially identified, and 31 articles met criteria for inclusion and underwent analysis. The most common outcome domain was pain. A pain outcome was reported in 17 (63%) studies. A motor outcome was reported in 10 (37%) studies; 6 (22%) reported a sensory outcome; 1 (4%) reported a composite outcome; 4 (15%) reported an electrodiagnostic outcome; 5 (19%) reported a patient-reported outcome; 3 (11%) reported an imaging outcome. Across the included studies, 21 unique outcomes were reported.

Conclusions: We have identified the outcome measures that have previously been utilized in studies on sciatic neuropathy. Previously used outcome measures fell into seven domains: motor outcomes, sensory outcomes, pain outcomes, patient-reported outcomes, electrodiagnostic outcomes, imaging outcomes, and composite outcomes. Pain outcomes were most commonly used across the included studies.
