Essential tremor is commonly described as an action tremor (i.e., it intensifies when one tries to use the affected muscles) or postural tremor (i.e., present with sustained muscle tone) rather than a resting tremor, such as is seen in Parkinson’s, which is usually not included among its symptoms. وغالبا ما يوصف الرعاش الاساسي برعاش العمل (وتزداد حدته عندما يحاول المرء استخدام العضلات المتأثرة) أو رعاش الوضعية (يظهر مع حركة العضلات المستمرة) بدلا من رعاش الراحة الموجود في مرض باركنسون، والتي عادة لا يدرج ضمن أعراضه.
تعريف الإنجليزية
