The technique of needle insertion into a muscle has become an increasingly important clinical routine not only for electromyographers but also for those who are treating patients with botulinum toxin. Even a highly trained electromyographer needs a manual for checking the insertion point or any landmarks to reach the target. There has been a classic for this purpose: Anatomic Guide for the Electromyographer: The Limbs, by Edward F. Delagi et al. Supplemented by superb illustrations, their book gained such a success that no other serious attempts to challenge its popularity had been made until Dr Geiringer's book appeared. As written in the introduction, this newcomer distinguishes itself from the classic in the following points: all muscles were thoroughly reviewed for their anatomy, and the method of localization is described in a relative scale rather than indicating with "finger-breadth" distances. The method has the ease of identifying muscles in smaller subjects
