PMR can affect the whole body, but tends to be most prominent closer to the core of the body. Walking can be difficult; steps become smaller, and the gait becomes awkward. There's also flattening of affect, meaning a lack of any facial expressiveness. I find that walking is affected first, and then speech when it gets more severe. Speech gets slow and quiet, and it becomes difficult to initiate. Subjectively, it feels like my brain is slow to fetch the motor scripts that go along with words. Written communication is easier because I just have to fetch the word cognitively, without the motor script. My Youtube channel has videos of psychomotor retardation and speech impairment.
