Erratum

The article “Clinical Update: Use and Abuse of Electro-physiologic Studies” by Richard T. Katz, MD, that appeared in the May/June 2000 issue, item 6, on page 10, posed the question: “Was the electrodiagnostic study performed with reliable equipment?” The author has requested the answer to read: “Some physicians have tried to incorporate more “cost-effective” devices as portable screening tools for measuring distal sensory or motor latencies.” References # 7 and # 8 are deleted.
