    Abstract Purpose spasticity is the result of a variety of lesions to the central nervous system and one of the most common causes of disability worldwide. Selective peripheral neurectomy (SPN) is a surgical procedure that permanently decreases focal spasticity. Authors’ objective is to provide recommendations, in terms of probabilities, for locating terminal motor entry points to muscles of the thigh, as alternatives for proximal incision sites to SPN. Methods the femoral, obturator, and sciatic nerves, and its corresponding motor rami, were systematically dissected on cadaveric specimens, and terminal motor entry points to each muscle of the thigh were located and carefully measured, relative to the length of the thigh. Measurement distributions were obtained and normal transformations were used when necessary. Results in 23 adult cadaveric specimens, 779 motor rami were dissected. Entry points locations are presented as a percentage of the length of the thigh in means and standard deviations, which roughly corresponds to 64 and 95% probability of finding a motor entry point. Conclusion Alternative incisions directly over the motor entry points, for the muscles of the thigh, may be helpful when considering SPN as treatment for focal spasticity. A prior degree of certainty of the location of the nerve to be severed, may simplify surgical approach.
