Modern medicine has rigorous standards when it comes to implementing any given treatment for any given disease. Many people are curious to know whether acupuncture is an effective method of expediting or enhancing stroke recovery after acute stroke. It appears after several studies and a full Cochrane review that the evidence is simply not sufficient to support a beneficial role for acupuncture in acute stroke. The main reason for this is that the studies performed are of poor quality or too small to allow the experts to derive any meaningful conclusions. Therefore more studies will need to be performed in the future to prove or disprove a beneficial (or harmful) effect of acupuncture in recovery from stroke.
Having said this, it probably is OK to give acupuncture or other alternative forms of medicine a try, but do it safely by discussing it with your doctor before you do. More importantly, you should reserve trials of these unverified, yet expensive treatment options, after all conventional and proven therapies have already been tried without success.
