RESUMO
BACKGROUND: Some stroke survivors suffer from involuntary movement, which often disturbs upper-limb function, but there are few effective modality options. CASE REPORT: A 70-year-old man presented with persisting right-upper-limb hemiballism due to left thalamic hemorrhage ten years before. We provided inpatient rehabilitation, including repetitive-facilitative exercise and task-related training, and prescribed clonazepam from day 5 after admission. However, the affected upper limb showed no significant change and remained nonfunctional. When we introduced mirror therapy (MT) to the rehabilitation program on day 14, hemiballism immediately decreased during the MT session, so we added daily MT sessions of 20 min/day. At discharge on day 42, he was able to use his right hand for eating meals and folding laundry. CLINICAL REHABILITATION IMPACT: This shows that MT may have the potential to be a novel therapeutic method for treating involuntary movement. Further research is needed to elucidate mechanisms by which MT may reduce hemiballism.
