Muscle spasticity, also referred to as tightness or stiffness, is a symptom of certain neurological conditions. It is characterised by an abnormal increase in muscle tone, causing certain muscles to contract all at once. Spasticity affects over 12 million people worldwide, including a large proportion of those with cerebral palsy and multiple sclerosis. The condition can range from mild stiffness to severe, painful, uncontrollable muscle spasms, and can interfere with daily activities and cause difficulty in performing basic hygiene tasks. Treatment options include physical therapy, medication, surgery, and botulinum toxin injections.

What You'll Learn
Muscle spasticity is a symptom of cerebral palsy
Spastic cerebral palsy is the most common type of cerebral palsy, accounting for about 70% to 80% of cases. It is caused by damage to the part of the brain that controls muscle tone and movement, resulting in stiff muscles and involuntary movements. This damage can occur due to a lack of oxygen to the brain, a brain injury, or, less commonly, a genetic abnormality.
The symptoms of spastic cerebral palsy can vary in severity, ranging from mild tightness in the muscles to severe, painful, and uncontrollable stiffness and spasms. It can affect muscles in any part of the body but is most commonly found in the leg muscles. In children with spastic cerebral palsy, the legs may pull inward and cross at the knees, a motion known as "scissoring." Arm muscles may also be affected, with children experiencing difficulty in performing tasks and a reduced range of motion.
Treatment for spasticity in cerebral palsy aims to relax the muscles, relieve pain and stiffness, and improve muscle flexibility and coordination. A multidisciplinary team of healthcare professionals is often involved, including neurologists, physical therapists, and speech and language pathologists. Treatment options include physical therapy, medication, and in some cases, surgery, such as rhizotomy. While there is no cure for spasticity, these treatments can help manage symptoms and improve the quality of life for individuals with spastic cerebral palsy.

It is also a symptom of multiple sclerosis
Muscle spasticity is a symptom of multiple sclerosis (MS). Spasticity is a symptom and characteristic of certain neurological conditions. It is caused by damage to the brain, spinal cord, or motor nerves, and it affects over 12 million people worldwide. Spasticity causes certain muscles to contract all at once, either when moving or at rest, and it can interfere with movement and speech. It is often described as "MS spasticity".
In the context of multiple sclerosis, spasticity typically occurs in the leg, groin, and buttock muscles, which help individuals stand and balance in an upright position. It can also occur in the back, although this is less common. Mild spasticity in these areas may not be painful and can sometimes offer extra support for standing or turning. However, more severe spasticity can cause significant discomfort and pain if not treated.
Spasticity in MS is a result of demyelination along the nerves of the brain and spinal cord that control movement. It can cause muscle stiffness, spasms, and involuntary contractions, which can be painful. The severity of spasticity can vary, and it can affect movement in different ways. For example, flexor spasticity can cause the legs and hips to lock in a bent position, while extensor spasticity can result in stiff muscles holding the legs straight and occasionally crossed at the ankles.
There are various treatments available to manage spasticity in MS, including exercise, physical therapy, medication, surgery, and complementary and alternative medicine (CAM) therapies. Aquatic therapy, braces, and other devices can also help. Drugs and therapies, such as physiotherapy and occupational therapy, can be particularly useful in managing muscle spasms and stiffness associated with MS. Relaxation techniques, such as progressive muscle relaxation and deep breathing, as well as acupuncture, can also help reduce spasticity.

Spasticity can be caused by brain or head trauma
Spasticity is a disruption in muscle movement patterns that causes certain muscles to contract all at once. It is a symptom and characteristic of certain neurological conditions. It can affect muscles in any part of the body but is most common in the leg muscles.
Spasticity is caused by uncontrolled overactivity of muscles due to disrupted signals from the brain. It is common in persons with more severe traumatic brain injuries (TBIs). A traumatic brain injury happens when something strikes or penetrates the head. It may affect how you think, feel, behave, move, and remember. A brain injury may affect the flow of nerve messages between the brain and the muscles, changing muscle tone, movement, sensation, and reflexes.
Spasticity may not develop right after a brain injury but may manifest within six months of the injury. The onset of spasticity following a TBI can be rapid, beginning as early as one week following injury. During the first year, muscle tone may change dramatically. The symptoms and degree of spasticity vary for each person and can include sudden, involuntary tightening or relaxing of a limb, or jerking of muscles in the trunk (chest, back, and abdomen).
Spasticity can be treated with medication, physical therapy, or injection therapy. The right treatment may improve comfort, mobility, and independence. However, some people may find that these treatments do not work well or cause intolerable side effects.

Infections like meningitis can cause muscle spasticity
Spasticity is a neurological condition characterised by abnormal muscle tone or stiffness, which can significantly impair bodily functions and daily activities. It is a symptom and characteristic of certain neurological conditions. It causes certain muscles to contract all at once, either when moving or at rest. The muscles remain contracted and resist stretching, which interferes with movement and can also affect speech and gait. Spasticity can vary in severity, ranging from mild muscle tightness to severe, painful, uncontrollable stiffness and spasms.
Meningitis typically presents with symptoms such as fever, severe headache, neck stiffness, nausea, vomiting, and light sensitivity. It is crucial to seek immediate medical attention if meningitis is suspected. The inflammation caused by meningitis can affect the brain's ability to send proper signals to the muscles, leading to spasticity. This condition can cause abnormal muscle contractions, stiffness, and spasms, which can be painful and impact an individual's ability to perform daily tasks.
The treatment of spasticity aims to relax the muscles, relieve pain and stiffness, and improve overall comfort, mobility, and independence. A multidisciplinary team of healthcare professionals is often involved in managing spasticity, including neurologists, physiatrists, physical therapists, and occupational therapists. While there is no cure for spasticity, various treatments can help alleviate symptoms and improve quality of life for those affected.

Spasticity can be treated with medication and physical therapy
Spasticity is a symptom of certain neurological conditions, causing muscles to contract all at once, which can affect movement and speech. It is often painful and can cause stiffness and spasms. Spasticity can interfere with daily life, making it difficult to perform basic tasks and affecting sleep. It can also cause permanent joint deformity, urinary tract infections, constipation and pressure sores.
Physical therapy for spasticity focuses on lower extremity stretching and strengthening exercises and mobility training. Therapeutic interventions can also include hippotherapy, aquatics, ultrasonography, electrical stimulation and biofeedback. Physical therapy can help to improve muscle flexibility, range of motion, coordination and strength.
Oral medications are commonly used to treat spasticity, particularly in severe cases, such as when a patient is unable to stretch or lengthen muscles. Common oral medications include baclofen, dantrolene sodium, diazepam and tizanidine. However, these medications can have side effects such as drowsiness, dizziness and, at high doses, sedation and changes in mood and cognition. Injections are another form of medication that can be used to treat spasticity. Botulinum toxin and phenol injections can be used to selectively reduce tone in muscles causing tightness or spasms. Injections can improve the ability to stretch, decrease pain and improve gait and range of motion.
