Botulinum neurotoxin (BoNT) injection is an effective treatment of spasticity in upper and lower limbs. Accuracy of injection needle placement in target muscles is of great importance in maximizing effectiveness of the treatment, and avoiding both treatment failure and adverse events such as weakening of adjacent musculature. Various guidance techniques improve effectiveness and avoid side effects, including anatomical landmark location and palpation, electromyographic guidance, and ultrasound guidance. In recent years, the availability of portable ultrasound devices has facilitated the application of ultrasound guidance, which is quick, painless, and now readily available. This chapter uses photographs, anatomical illustrations, and ultrasound images to illustrate injection techniques for specific muscles involved in the common patterns of spastic posturing.
