Systematic relaxation may help to reduce the jerking prior to sleep.
Dear Shamrock:
Sorry that your having jerking movements. I will assume that your myoclonic jerks are actual jerks and not just perceived jerks. Yes, myoclonic jerks and hypnagogic jerks can be the same. They can both occur into or out of sleep. They are normal and can be present or absent at any one time. Myoclonic jerks can also be associated with epilepsy, hypoxia, cervical cord damage, metabolic disease, toxic exposure, etc. So, one needs to figure out if these are just sleep related events or other types of events. You might have to repeat the sleep study, or get a video-EEG monitored evaluation to be sure. Since you have a history of a head trauma, I would bet the latter would be a good first choice. The length of time that you could have this would depend on the etiology, as would how to manage it. So, I can't tell you much without knowing the etiology.
Sincerely,
