This second edition continues to offer practitioners access to a huge database of normal values, developed using the most modern scientific protocols, for virtually any patient population! Normal ranges take into account age, sex, height, and body mass index for a wide range of demographic groups to provide a complete set of reliable values for everyday clinical practice. Many studies are updated. When possible, studies with normal values based on larger groups of subjects with varied demographics are included. Side-to-side and same-limb comparisons of different nerves are often included, with the acceptable differences listed in the “helpful hints” section of the appropriate chapters. Included for reference is a schematic of the brachial plexus inside the front cover, to be used as an aid in determining which nerves to study in complex cases.
Benefits of this outstanding reference: Provides reliable, state-of-the-art normal ranges; Results are presented with the mean, standard deviation, the range, and the upper or lower limit of normal; Covers up-to-date techniques for conducting nerve tests; Provides written descriptions and schematic depictions of electrode placement; Includes typical waveform appearance of the most common studies; Codifies the acceptable differences in latency, amplitude, nerve conduction velocity, etc., between nerves of the same or opposite limbs, allowing for a more precise diagnosis; Offers a concise list of references and suggested readings for each study; Provides helpful hints for performing each study; Includes advantages and pitfalls of alternative techniques.
This bedside reference offers a comprehensive, up-to-date set of normal values for clinical use that can be used to quickly review how to perform a given study or to look up reference values that have not been committed to memory. By following the described techniques, the user-trainee or clinician-will have normal values that can be used with confidence
