I have had limited success by using the ICU on tarantulas that had a long shippping trip.
Get a solid container (One that is slightly larger than the T and is not clear) and poke some holes through it (about 3 or 4 for oxygen only)
Place a mat of damp paper towel and a wad of damp paper towel inside the container and then put the T inside. Now you need warmth and a dark quiet place to put the tarantula.
I use the bathroom because it is almost always dark in there and it is an easy place to control temp and humidity levels buy simply running a hot shower or drawing a hot bath and leaving it there. Any place that is warm and dark will do though.
Change the paper towel daily for more damp paper towel.
This should bring your T back to 100% within a week or so.
Our male C. cyaneopubescens looked very much like that right after he was shipped to us. He was packaged very well and the weather was fair the whole way the spider was shipped. He just stood in weird positions like that. Although he would eventually move if we nudged him with a paintbrush, his response was slow. We also put him in an ICU for about 3-4 days and he seemed better after that and became much more active. I would try putting the spider in an ICU in a warm room. I have read about spiders that seemed dead when they arrived being revived in a few days by being slowly warmed up. Good Luck!!
