Muscle twitching is a common concern for stroke patients, and it can be a sign of several conditions. While twitching can be a positive sign of recovery, indicating that the muscles are waking up, it can also be a symptom of more serious issues, such as spasticity, clonus, chorea, athetosis, or dystonia. Spasticity, a condition that causes stiff or rigid muscles, affects 25% to 43% of stroke survivors in the first year and can lead to significant difficulties in daily life. Treatment options for spasticity include physical therapy, medication, and surgical interventions. Other movement disorders associated with stroke include myoclonus, tics, hemiballism, and flexor spasms, which can develop immediately after a stroke or emerge later as delayed-onset progressive movement disorders. Seeking medical advice is crucial for proper diagnosis and treatment planning.

What You'll Learn
Muscle twitching as a sign of recovery
Muscle twitching after a stroke is a common occurrence, and it can be a sign of spasticity, a condition that causes stiff or rigid muscles. Spasticity occurs when a muscle involuntarily contracts during movement, commonly affecting the elbow, wrist, and ankle. It can cause difficulty with everyday tasks and reduce one's quality of life. While there is no cure for post-stroke spasticity, treatments and lifestyle changes can help manage symptoms and improve mobility.
Movement disorders are also associated with stroke, and muscle twitching can be a symptom of these disorders. These include myoclonus, tics, and hemiballism/hemichorea, among others. Some stroke patients experience muscle twitching right before they regain movement, especially in those with hemiplegia (paralysis of half the body). In such cases, muscle twitching can be seen as a positive sign of recovery.
If you or someone you know is experiencing muscle twitching after a stroke, it is important to consult with a medical professional. A physical rehabilitation specialist, such as a physical therapist or occupational therapist, can prescribe specific exercises or stretches to improve blood flow to the affected muscles and enhance neurological control. These rehab exercises are particularly beneficial if the twitching is a sign of your muscles "waking up" after a stroke.
Additionally, there are other treatment options available, such as oral medications, functional electrical stimulation, and intrathecal baclofen therapy. Botox or medication may also be recommended if the muscle twitches are painful or limiting mobility. It is important to work closely with your healthcare team to find the best treatment option for your specific needs and to maximize your recovery potential.
While muscle twitching can be a sign of recovery, it is important to note that everyone's experience with stroke is unique, and the presence or absence of muscle twitching does not necessarily indicate the success or failure of recovery. The road to recovery can be challenging, but with the right support and treatment, it is possible to improve and regain control over your body.

Spasticity and other post-stroke conditions
Spasticity is a common post-stroke condition, affecting 25% to 43% of survivors in the first year after their stroke. It causes stiff or rigid muscles due to involuntary muscle contractions during movement, commonly in the elbow, wrist, and ankle. This can make stretching the muscle difficult and, if left untreated, can result in contracture, where joints in the arm and leg become stuck or frozen in an abnormal and possibly painful position. Spasticity can cause significant difficulty with daily tasks, increasing the burden on caregivers and reducing the patient's quality of life. Treatment options include physical therapy, modality and pharmacological treatments, neurolysis with phenol and botulinum toxin, and surgical treatment.
Muscle twitching after a stroke is often associated with spasticity, but it can also indicate other issues. In some cases, it may be a sign of recovery, and physical rehabilitation exercises can help improve neurological control over the muscles. However, if the twitching is caused by the worsening of a condition, medical advice should be sought, and physical therapy can still be beneficial. Botox or medication can help relieve symptoms and improve mobility.
Tremors are another possible cause of muscle twitching after a stroke, and they can have a delayed onset, manifesting months later. Other involuntary movement disorders that can cause muscle twitching include clonus, chorea, athetosis, and dystonia. Hemiballism/hemichorea is the most common movement disorder reported after a stroke, present in 40% of cases, and is characterized by vigorous, irregular, poorly patterned, high-amplitude movements of the limbs on one side of the body. Tics, involving involuntary twitches or sounds, have also been reported after strokes, particularly in specific brain regions.
Overall, muscle twitching after a stroke can have various causes, and it is important to consult with medical professionals, such as physical rehabilitation specialists, to receive a proper diagnosis and treatment plan.

Involuntary movement disorders
Flexor spasms are another involuntary movement disorder that can occur after a stroke, although they are highly uncommon. They consist of intermittent flexor spasms in the right leg, arm, and hand, with no accompanying jerky movements or extensor muscle contractions. These spasms can be an early sign of an ongoing stroke in the basal ganglia.
Spasticity is a common post-stroke condition, affecting 25-43% of survivors in the first year, and is characterised by stiff or rigid muscles. It occurs when a muscle involuntarily contracts during movement and can affect the elbow, wrist, and ankle. Spasticity can cause significant difficulty with daily tasks and reduce quality of life. Treatment options include physical therapy, medication, neurolysis, and surgical interventions.

Treatment options for muscle twitching
Muscle twitching is usually not serious and often goes away on its own. However, if the twitching is persistent or occurs in multiple places, it may be a good idea to consult a doctor. In the context of a stroke, muscle twitching is often a sign of spasticity, a common post-stroke condition that causes stiff or rigid muscles. It occurs when a muscle involuntarily contracts when you move, commonly affecting the elbow, wrist, and ankle. If left untreated, spasticity can lead to painful and abnormal joint positions called contractures.
Physical Rehabilitation
Physical rehabilitation, such as specific exercises or stretches, can help improve blood flow to the affected muscles and enhance neurological control over them. Rehabilitation exercises are especially beneficial if the twitching is a sign of your muscles "waking up" after a stroke. Working with a trained physical therapist or occupational therapist can help maximize your recovery and improve muscle control.
Medications
Oral medications can help relax the nerves, preventing them from continuously sending contraction signals to the muscles. Common side effects of these medications include weakness, drowsiness, or nausea. Intrathecal baclofen therapy (ITB) is another option that delivers medication directly to the spinal cord through a surgically implanted pump, minimizing side effects associated with oral medications.
Botox
If muscle twitches are painful or limiting your mobility, Botox injections can be considered. Botox can help relieve symptoms of spasticity and muscle tightness, improving mobility and allowing for more physical activity, which further stimulates the brain and muscles.
Functional Electrical Stimulation (FES) or Neuromuscular Electrical Stimulations (NMES)
FES or NMES delivers a mild to intense shock to the affected muscle, activating nerves and improving movement. The sensation can range from a mild tingling feeling to a burning sensation, depending on the intensity. While there is insufficient evidence of its effectiveness in improving functional gait or hand use, NMES combined with therapy may improve spasticity.
Addressing Underlying Causes
Muscle twitching can be caused by various factors, including lack of sleep, caffeine consumption, nutrient deficiencies, overexertion, or stress. Addressing these underlying causes through lifestyle changes can help reduce the occurrence of muscle twitches. Additionally, in some cases, muscle twitching may be a symptom of more serious underlying conditions, such as multiple sclerosis (MS) or amyotrophic lateral sclerosis (ALS). Seeking prompt medical advice and working with a doctor on a treatment plan is crucial in managing and treating the underlying condition.

Hemiballism/hemichorea and other dyskinesias
Hemiballism/hemichorea is a hyperkinetic movement disorder characterised by involuntary, violent, coarse, and wide-amplitude movements. It is the most common movement disorder reported after a stroke, present in 40% of cases. It is often considered a severe type of chorea, which consists of brief, arrhythmic, non-repetitive movements that appear to move from one muscle to the next. Chorea is characterised by continuous, random, jerking movements involving mainly distal muscles.
Hemiballism is caused by dysfunction in the central nervous system of the contralateral side, with lesions occurring in regions functionally connected to the posterolateral putamen. It is often associated with structural lesions, particularly in the subthalamic nucleus or its pathways. In addition, metabolic disorders such as nonketotic hyperglycemia can cause hemiballism, especially in elderly diabetic patients.
Other dyskinesias associated with hemiballism include orobuccal, oromandibular, lingual, and dystonic movements. Treatment options for hemiballism-hemichorea include addressing any underlying infections, such as HIV or cerebral toxoplasmosis, and controlling hyperkinetic movements. Benzodiazepines have been shown to be effective in treating patients with kinesigenic dyskinesias.
It is important to note that muscle twitching after a stroke can be a sign of spasticity, which is a common post-stroke condition causing stiff or rigid muscles. Spasticity can lead to significant difficulties in daily living tasks and impact quality of life. Treatment options for spasticity include oral medications, functional electrical stimulation, and intrathecal baclofen therapy. Physical rehabilitation, such as specific exercises and stretches, can also help improve blood flow to the affected muscles and enhance neurological control.
