    La prevalencia exacta del dolor neuropático periférico es desconocida. La complejidad y las múltiples presentaciones clínicas dificultan su abordaje. Por ello, se antoja necesario conocer los mecanismos patobiológicos que acontecen en los pacientes con este tipo de afección. La fisioterapia ha emergido en los últimos años como una alternativa o complemento a los tratamientos médicos convencionales. En este trabajo, se introducen aspectos fundamentales del dolor neuropático y las neuropatías por atrapamiento, y se revisa el conocimiento relacionado con los mecanismos de acción de las distintas técnicas de fisioterapia sobre el dolor neuropático y el proceso fisiopatológico de las neuropatías por atrapamiento.

    Sample size calculation is one of the most important aspects in the planning of most research, and an insufficient sample can lead to the uselessness of the research itself. Traditionally, power-based sample size calculations have been used, but now precision-based calculations have begun to be implemented. This paper presents recommendations for calculations for randomised clinical trials, multiple linear and logistic regression models, reproducibility analysis, and multivariable predictive models, along with some practical examples of their implementation, as well as some considerations regarding the development and use of pilot study data when planning a sample size calculation.
