A deduction of the Bohmian quantum formalism is performed by means of a deformed Fisher information functional, from which a deformed Cram\\'er-Rao bound is derived. Lagrangian and Hamiltonian formulations, inherited by the $q$-algebra, are also developed. Then, we illustrate the results with a particle confined in an infinite square potential well.
