Spasticity is abnormal muscle tightness due to extended muscle contraction. It is typically linked to damage to the spinal cord, brain, or nerves.
Your doctor may ask these questions to check for this disease:
Treatment relies on the cause. Physical therapy, occupational therapy, and prolonged stretching can help reduce spasticity. Splinting, casting, and bracing can maintain range of motion and flexibility.

Q.
Trapped? Why Your Body is Locked: Locked In Syndrome & Medical Next Steps
A.
Locked-in syndrome is a rare but critical condition where a person is fully conscious yet cannot move or speak, usually from a brainstem stroke; preserved blinking or vertical eye movement may allow communication, and any sudden onset of these symptoms is a medical emergency requiring 911, immediate CT or MRI, and stroke therapy. There are several factors to consider that can affect your next steps, including look-alike conditions, diagnostic tests, ICU support, rehabilitation, spasticity management, communication devices, prognosis, and emotional care; see the complete details below.

Q.
Big Toe Fanning Up? Why Your Babinski Reflex Matters & Medical Next Steps
A.
Big toe moving up with toe fanning after stroking the sole is a positive Babinski reflex, which is normal in infants but in adults can signal a brain or spinal cord issue that needs prompt medical evaluation. There are several factors to consider, including accompanying symptoms like weakness, stiffness, balance changes, or sudden stroke signs that require emergency care. For what to do next, including when to seek urgent help, what tests doctors use, and conditions that can cause this finding, see the complete guidance below, as there are important details that can change your next steps.

Q.
Always Tense? Why Your Body Is Stuck & Somatic Yoga Medical Next Steps
A.
There are several factors to consider. See below to understand more. Chronic tightness often reflects a nervous system stuck in a protective stress response, where somatic yoga with slow, mindful contraction then release can reset muscle tone more reliably than stretching, yet progressive stiffness, spasms, weakness, one sided changes, or trouble walking may signal spasticity or other medical issues, so use the spasticity symptom check and see a clinician, with step by step guidance below.

Q.
Feeling Stiff? Why Your Muscles Are Hypertonic + Medical Next Steps
A.
Persistent stiffness that resists stretching may be hypertonicity, meaning increased resting muscle tone. Common, reversible triggers include stress, poor posture, and overuse, while serious causes can involve the nervous system such as stroke, multiple sclerosis, or spinal cord or brain injury. There are several factors to consider, including urgent warning signs, how doctors diagnose it, and treatments from physical therapy to medications. See below for the complete details and the next steps that could impact your healthcare decisions.

Q.
Is Your Body "Jumping"? Why Your Reflexes Misfire & How to Find Relief
A.
Sudden body jumps are usually reflex related and often harmless from hypnic jerks, stress, caffeine, fatigue, electrolyte shifts, or medications, but persistent stiffness, exaggerated reflexes, weakness, numbness, or other neurologic changes can point to spasticity or brain and spinal cord conditions that need prompt evaluation. Relief can come from lowering caffeine, staying hydrated and correcting electrolytes, improving sleep and stress control, stretching and physical therapy, and when needed targeted medicines or procedures. There are several factors to consider, and important red flags and evaluation steps are outlined below to guide your next steps.
