Nonparametric inference is not necessarily required for matched pairs alone; it depends more on the distribution of the data and the size of the sample rather than the pairing of observations. Matched pairs can be analyzed using parametric methods if the differences between pairs are normally distributed or if the sample size is large enough for the Central Limit Theorem to apply.
