I don't know if it could be useful to you, but:
- Swimming in a salt pool or taking a bath can help with tactile and proprioceptive issues, because of the weight of the water
- Vestibular, I use a sitting hammock twice a day (using swings in the park can help as well) and a mini-trampoline helps too
- I also need a heavy blanket to sleep well, as it wakes up my skin and helps me "know" where my body stands in space. Heavy vests or compressions vests can be useful too.
- Many people find that brushing their skin with a surgery kind of brush also helps during tactile hypo moments. I use a natural bristle brush and sometimes do self-massages and they help too.
I hope you find something that helps you!
