We have reviewed the clinical evidences regarding tilt and recline, and found there are several studies or best practice guidelines suggesting that the tilt and recline sequence is important to reduce shear and sliding:
First tilt then recline afterwards.
When bringing the client upright again, the sequence should be recline first then tilt.
It would seem that the most shear would be induced when going upright from a recline and tilted position.
