Abstract
BACKGROUND: Peripherally induced movement disorders represent a rare and debated complication of peripheral trauma. It is difficult to determine a causal relationship between peripheral injuries and subsequent movement disorders. CASES: Here, we introduce and characterize four patients with post-surgical scar-associated movement disorders, a peripherally-induced rippling movement disorder confined to the muscles just under a long surgical incision scar, appearing weeks to months after surgery. This novel 'scar dancing' syndrome does not spread to adjacent muscles and persists during sleep. CONCLUSION: Scar dancing syndrome expands the phenotypic spectrum of peripherally induced movement disorders, in which movement disorder is confined to a long surgical incision site.
