There is no cure for the<unk> . However, the symptoms can be reduced and managed to some degree by keeping the<unk>  hand occupied and involved in a task, for example by giving it an object to hold in its grasp. Specific learned tasks can restore voluntary control of the hand to a significant degree. One patient with the "frontal" form of<unk>  hand who would reach out to grasp onto different objects (e.g., door handles) as he was walking was given a cane to hold in the<unk>  hand while walking, even though he really did not need a cane for its usual purpose. With the cane firmly in the grasp of the<unk>  hand, it would generally not release the grasp and drop the cane in order to reach out to grasp onto a different object. Other techniques proven to be effective includes; wedging the hand between the legs or slapping it; warm water application and visual or tactile contact. Additionally, Wu et al. found that an irritating alarm activated by biofeedback reduced the time the<unk>  hand held an object. In the presence of unilateral damage to a single cerebral hemisphere, there is generally a gradual reduction in the frequency of<unk>  behaviors observed over time and a gradual restoration of voluntary control over the affected hand. Actually, when<unk>  originates from focal injury of acute onset, recovery usually occurs within a year. One theory is that neuroplasticity in the bihemispheric and subcortical brain systems involved in voluntary movement production can serve to re-establish the connection between the executive production process and the internal self-generation and registration process. Exactly how this may occur is not well understood, but a process of gradual recovery from<unk>  when the damage is confined to a single cerebral hemisphere has been reported. In some instances, patients may resort to constraining the wayward, undesirable and sometimes embarrassing actions of the impaired hand by voluntarily grasping onto the forearm of the impaired hand using the intact hand. This observed behavior has been termed "self-restriction" or "self-grasping". In another approach, the patient is trained to perform a specific task, such as moving the<unk>  hand to contact a specific object or a highly<unk> t environmental target, which is a movement that the patient can learn to generate voluntarily through focused training in order to effectively override the<unk>  behavior. It is possible that some of this training produces a re-organization of premotor systems within the damaged hemisphere, or, alternatively, that ipsilateral control of the limb from the intact hemisphere may be expanded. Another method involves simultaneously "muffling" the action of the<unk>  hand and limiting the sensory feedback coming back to the hand from environmental contact by placing it in a restrictive "cloak" such as a specialized soft foam hand orthosis or, alternatively, an everyday oven mitt. Other patients have reported using an orthotic device to restrict perseverative grasping or restraining the<unk>  hand by securing it to the bed pole. Of course, this can limit the degree to which the hand can participate in addressing functional goals for the patient and may be considered to be an unjustifiable restraint. Theoretically, this approach could slow down the process through which voluntary control of the hand is restored if the neuroplasticity that underlies recovery involves the recurrent exercise of voluntary will to control the actions of the hand in a functional context and the associated experiential reinforcement through successful willful suppression of the<unk>  behavior.
