Plain-English summary
A group of 61 dogs showing signs of back pain or limping in their back legs were evaluated for a condition called lumbosacral foraminal stenosis, which can cause nerve compression. The dogs underwent MRI scans and electrodiagnostic tests to help determine the cause of their symptoms. While some tests showed differences between dogs with and without the condition, the results were not definitive enough to diagnose all cases. The study suggests that these tests can help veterinarians make better decisions when diagnosing and managing back pain in dogs.

Abstract
BACKGROUND: Development of management strategies for lumbosacral stenosis in dogs is hampered by the lack of objective diagnostic criteria and outcome measures. OBJECTIVE: To explore the suitability of electrodiagnostic tests as ancillary diagnostic aids, inclusion criteria, or outcome measures. SAMPLE POPULATION: Sixty-one client-owned dogs with clinical signs of lumbosacral foraminal stenosis. METHODS: A blinded, cross-sectional cohort study. Fifty-one dogs exhibiting apparent lumbosacral pain or pelvic limb lameness with no detected orthopedic cause had blinded review of magnetic resonance imaging (MRI), allowing classification as affected with foraminal stenosis (25 dogs), unaffected (20 dogs), or another diagnosis (6 dogs). The presence of electromyographic changes and tibial neurography variables were compared between groups. RESULTS: Cord dorsum potential onset latency, F-wave onset latency (both corrected for limb length), and F-ratio were increased in dogs with lumbosacral foraminal stenosis versus those without, although there was overlap of the values between groups. The proportion of dogs with electromyographic changes was not significantly greater in MRI-affected dogs. CONCLUSION: Electrophysiological testing is a useful ancillary test, either to provide stricter inclusion criteria and outcome measures or to aid clinical decision-making in equivocal cases.
