A possible modification of the V-A weak interaction at high energy is studied through the introduction of an intermediate vector boson with derivative couplings or of a phenomenological momentum dependent leptonic vector current. It will be shown that a small contamination of a certain derivative coupling changes the sign of the longitudinal polarization of the muon in the neutrino nucleon inelastic scattering in the scaling region and let the ratio 0($/o(v) increase as the neutrino energy gets larger, while a different momentum dependent vector current leaves the sign of the polarization and the ratio o(v)/o(v) unchanged.
