<unk>  (CMM<unk>  is a rare genetic neurological<unk>  which is characterized by<unk> ed<unk> , sometimes referred to as associated or synkinetic<unk> , most often in the upper extremity of the body. These<unk> s are voluntary intentional<unk> s on one, ipsilateral, side of the body that are<unk> ed simultaneously by involuntary<unk> s on the contralateral side. The reproduction of involuntary<unk>  usually happens along the head-tail axis, having a left-right symmetry. For example, if someone were to voluntarily make a fist with their left hand, their right hand would do the same. In most cases, the accompanying contralateral involuntary<unk> s are much weaker than the ipsilateral voluntary ones, although the extent and magnitude of the<unk> ed<unk>  vary across patients. This<unk>  has not yet been found to be associated with any other neurologic disease or cognitive disability, and currently, no cures nor means to improve signs or symptoms have been found. The congenital<unk><unk> s begin in infancy and persist throughout the patient’s life, often with very little improvement, or deterioration. Consequently, patients who do suffer from this<unk><unk>  have serious difficulty carrying out tasks that require manual dexterity or precision, such as playing a two handed musical instrument or typing on a keyboard, for their whole lives. Patients also often experience discomfort or pain in the upper limbs due to prolonged use of the same muscles. Therefore, quality of life can be severely hampered. CMM<unk> ’s prevalence in the world is thought to be less than 1 in 1 million people. Because of its rarity, researchers suggest that some mildly affected individuals may never be diagnosed. It is important not to confuse<unk> s, a rare genetically based neurologic disease, with acquired<unk><unk><unk> s that present themselves during one’s lifetime due to other reasons (stroke for example).
