The invention relates to a medicament or a method for treating mental disorders, in detail, ADHD comprising lurasidone, or a combination of lurasidone and a D4 receptor agonist. The pair of hinged plates are attached between the outsole and the upper in a forefoot portion of the shoe, and the spring biases the plates apart, so that energy is stored and returned during a propulsion phase of a gait cycle in a human step. A hopping parameter is determined based on a sequence defined by a cell specific seed.
