Hard flaccid syndrome

Hard flaccid syndrome is a condition where a person's muscles stay weak and stiff even when they are not in use. It might make it difficult for you to move your arms, legs, or other body parts. It happens when the nerves that send signals from your brain to the muscles get damaged. That means the muscles can't get the signals they need to move like they should. Treatments might include physical and occupational therapy, medications, or surgery to fix the nerve damage.
