The lumbar spine can be adjusted to sleep after surgery by the following methods: First, the mattress should choose a coconut palm mattress of moderate hardness to ensure adequate support for the lumbar region, and will not cause excessive squeezing of the lumbar muscles, which can make the lumbar muscles get sufficient rest and will not stimulate the lumbar surgical incision. Secondly, the side lying position should be chosen as far as possible during sleep, while soft cushions should be spaced between the legs to avoid double knee contact or double leg cross, with the aim of avoiding twisting of the lumbar spine in the side lying position and reducing the stimulation of the surgical site. Through the above methods, pain at the surgical site can be avoided and the quality of sleep can be improved.
