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.
