Tremor is a movement disorder with an involuntary, relatively rhythmic pattern, related to demyelination in the cerebellum and its pathways. It includes intention tremor, or tremor triggered by voluntary movement, affecting any muscle group including arms, legs, trunk, head, vocal cords, jaws lips, and tongue. Tremor in MS is difficult to manage and is not reliably improved by medication. Tremor can add significantly to both fatigue and functional disability in MS.


Consultation with occupational and physical therapy around issues related to activities of daily living and safety may be helpful. Medications for tremor in MS have limited benefit.
