Involuntary, repetitive muscle movements or spasms, often affecting the face or limbs.
Because the rating hinges on frequency, severity, and the muscle groups involved, useful evidence speaks directly to each of those factors. Medical records that document how often the tics occur, which muscles or muscle groups are affected, and how forceful or disruptive the movements are will be central. Notes from neurology or other treating providers that describe the tics as mild, moderate, or severe in clinical terms are particularly helpful. Results from any neurological examinations that capture the character and extent of the movements also support the record. Statements from you or people who live or work with you describing how often the tics happen, how long episodes last, and how they affect your ability to work or carry out daily activities can show what the medical records may not fully capture about day-to-day impact.
