Scintillation observations of the nearby single millisecond pulsar (MSP) PSR J0030+0451 were carried out with the Parkes 64 m radiotelescope at three different epochs in 1999. From analysis of the dynamic spectrum we obtained the amplitude of the electron density power spectrum log<C_N²≥~-3.33 and a scintillation velocity V_iss≲15km/s. This result shows that the Shklovskii effect on the spin-down rate {dot}(P) is negligible. We also performed a correlation analysis between pulsar proper motions (V_pm) and scintillation velocities (V_iss) using updated measurements for a sample of 77 objects, 17 of which are MSPs. The full sample shows a correlation coefficient r_s≃80% at an extremely high significance level, while for the MSP sub-sample (excluding 2 outliers) we obtain r_s≃90%.
