Effects of Dry Needling on Spasticity in Multiple Sclerosis Evaluated Through the Rate-Dependent Depression of the H Reflex: A Case Report
Abstract
Spasticity is a common symptom of multiple sclerosis (MS) which affects mobility. Dry Needling (DN) has shown a reduction in spasticity in neuromuscular conditions such as stroke and spinal cord injury although the mechanism of action is still unclear. In spastic individuals, the Rate-Dependent Depression (RDD) of the H reflex is decreased as compared to controls and analyzing the effects of DN in the RDD may help to understand its mechanism of action.
Tolls, Schools, and Tips: The Reproduction of Social Inequality Through Day-to-Day Practices
Abstract
How is social inequality reproduced through day-to-day practices? In this commentary, we use the geographical context of Mexico City to argue that social inequality is maintained by “class work” of elites. Specifically, we discuss how (1) urban planning crystallizes class boundaries, (2) private school education reproduces them, and (3) tipping prevents their disruption.
Lessons from the famous 17th-century paradox of the Chevalier de Méré
Abstract
We take advantage of a combinatorial misconception and the famous paradox of the Chevalier de Méré to present the multiplication rule for independent events; the principle of inclusion and exclusion in the presence of disjoint events; the median of a discrete-type random variable, and a confidence interval for a large sample. Moreover, we pay tribute to our original bibliographic sources by providing two computational tools to facilitate the students' insights on these topics.
