Can image stabilization reduce shutter shock blur?

I’m considering a used Sony A7R, which is often reported to show shutter-shock blur at some shutter speeds. If I use the camera with a stabilized lens, can image stabilization reduce that blur, or is shutter shock too fast or too different in character for stabilization to correct? More generally, does lens-based or in-body stabilization help with shutter shock, and are there cases where it can make things worse?

There are advantages and disadvantages to lens based image stabilization. One of the advantages is that the IS can be tuned for the focal length of the lens and counteract motion on very long focal length lenses that would be much too large to do with a sensor based IS system. On the other hand, sensor based IS is better at dealing with other types of motion. Lens based IS can reduce the influence of camera based vibrations such as shutter shock (and mirror slap for camera that have mirrors) on lens movement. But they can't deal with it as effectively as cameras that incorporate IS into the camera's sensor. By far the best way to deal with shutter shock is to use a camera with an electronic curtain, rather than mechanical curtain, shutter.

Sometimes, but it depends on the stabilization system and camera design. In general, modern image stabilization systems work during the exposure and can reduce some vibration, including shutter shock. However, effectiveness varies by implementation.
Lens-based stabilization may help with camera vibration, but sensor-based stabilization is generally better at handling a wider range of motion. Some first-generation systems are less effective, and in some cases stabilization can even worsen shutter-shock blur rather than fix it.
For the Sony A7R specifically, community experience and testing discussed here suggest stabilization is not a guaranteed cure for its shutter-shock issues, and at least some testing showed IS could make results worse under certain conditions.
The most reliable fix for shutter shock is not stabilization, but reducing the source of vibration—especially by using a camera with an electronic front curtain/electronic curtain shutter instead of a fully mechanical shutter.
