Doubt has been cast over the accuracy of dermatome charts. This study investigated a large group of patients with known lumbar nerve root compression (NRC), and identified whether their radicular pain corresponded with the predicted distribution on a dermatome chart. The study included 209 patients that presented with lumbar radiculopathy. 106 were confirmed as L5 NRC and 103 as S1 NRC, by MRI. Each patient used an interactive computer assessment program to record their pain on a body map image. The coordinates were then used to compare the sensory distribution to a standard dermatome chart.Background
