First seen Mar 25, 2026 · Last updated Apr 29, 2026 · Updated 6 times

Summary

This study tests whether injections of incobotulinumtoxinA (Xeomin) can ease hand cramps and improve writing in people with focal hand dystonia, a condition that causes involuntary muscle contractions. About 48 adults will receive either the drug or a placebo, and they will rate their writing ability on a scale. The goal is to see if the treatment reduces symptoms and improves daily function.
