Thalamic stroke has a recovery time of about one year, says the National Institutes of Health. Formerly, recovery was considered complete within a period of six months, but trials show that improvements can continue to occur as long as a year after the stroke.
Of the 700,000 patients who suffer a stroke each year, about two-thirds live to start a rehabilitation program, states the NIH. Although rehabilitation is not considered a cure for stroke, it is a means to regaining most body function.
Thalamic pain suffered after a stroke is most likely a result of having a stroke in the thalamus, which controls sensory from the brain to the body, explains the NIH. Some pain experienced is not from nervous system damage, but is from mechanical issues resulting from muscle weakness, radiating from the shoulder area.
