  The measurement of the speed of gravitational waves (GWs) is useful to
distinguish general relativity from massive gravity. We propose a new
model-independent strategy to measure the speed of GWs with the distorted
pulsars. Theoretically, when the the GW frequencies from a distorted pulsar are
twice the frequencies of EM pulses, they should be emitted at the same time. By
measuring the arrival times of these two signals emitted at the same time, the
speed of GWs can be calculated with the time difference. Specifically, when the
glitches of pulsars are taken into consideration, some pulsars in our Galaxy
and nearby galaxies are potential to test our new strategy at high accuracy in
the foreseeable future. On the other hand, the new method is meaningful as a
motivation for future design of instruments.
