Exercise as medicine for rare muscle paralysis?
NCT ID NCT07194174
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a personalized strength exercise program can improve muscle function and reduce weakness attacks in adults with hypokalemic or hyperkalemic periodic paralysis. Over 24 weeks, 36 participants will be tested at the start, at 12 weeks, and after 12 weeks of supervised training. The goal is to see if exercise can ease symptoms and boost daily life.
