Is osteopathic manipulation therapy legit?

Hi all, I was wondering if OMM was supported by science.

"Osteopathy is a type of alternative medicine that emphasizes physical manipulation of the body's muscle tissue and bones.

OMM is used to treat many forms of bodily dysfunction including pain, discomfort, and limited range of motion caused by illness or injury. The goal of OMM is to remove these barriers in order to achieve wellness.”
