I recall reading, that when Mir would get a new module added, after it was docked, a cosmonaut would stand in, feet on one wall, hands on the other, and try to shake it, to ensure the docking seal was completed properly.
The maneuver was called the Rezonans (or Resonance) experiment. It occurred on Soyuz 26 / Salyut 6 / Soyuz 27  and on MIR EO-1 with Soyuz T-15 / MIR / Progress 25 .
Do they still do this for new modules at the ISS?
Does it differ US vs Russian side, perhaps due to the different nature of the docking/berthing connectors?
That is, compare the CBM vs PMA vs Russian Active vs Russian Passive docking ports.
