What You'll Learn
Spasticity is a motor disorder
The condition can vary in severity, ranging from mild feelings of muscle tightness to severe, uncontrollable stiffness and spasms. Spasticity can lead to complications such as interference with daily functions, hygiene, comfort, and nursing care. It can also cause contractures, increasing the risk of pressure ulcers and subsequent infections. Spasticity poses an increased risk of subluxation, dislocation, and heterotopic ossification. However, it can be beneficial for some patients, allowing them to stand or bear weight, reducing the risk of osteoporosis, improving circulation, and promoting overall mental health.
There are several treatment options for spasticity, and patients often undergo multiple treatments simultaneously. Treatment goals include relaxing the muscles, relieving pain and stiffness, and improving muscle flexibility, range of motion, coordination, and strength. Physical therapy focuses on lower extremity stretching and strengthening exercises, mobility training, and improving the performance of daily tasks. Oral medications are used in combination with other therapies, and only when symptoms interfere with daily functioning or sleep. Botulinum toxin injections can be used to paralyse the spastic muscle, preventing contraction. Casting or bracing prevents involuntary spasms and reduces muscle tightening. Selective dorsal rhizotomy (SDR) is a surgical procedure that rebalances electrical signals sent to the spinal cord by cutting selective nerve roots, decreasing muscle stiffness.
The management of spasticity requires careful consideration, as some patients rely on certain aspects of the condition to maintain enough tone for functions such as standing or walking. Early identification and management of spasticity are crucial to prevent permanent loss of joint range and to monitor and manage the condition effectively.

Muscle movement patterns are disrupted
Spasticity is a disruption in muscle movement patterns, causing certain muscles to contract all at once. It can affect movement and speech. The condition is typically a result of an insult to the central nervous system or motor neurons. It may occur as a primary condition, such as in degenerative disorders, or as a result of secondary causes such as spinal cord injury, brain trauma, or inflammatory conditions like multiple sclerosis. Spasticity can vary in severity, ranging from mild feelings of muscle tightness to severe, painful, and uncontrollable stiffness and spasms. It can interfere with daily activities such as dressing and bathing and cause sleep disruption.
Spasticity is often associated with neurological conditions and can affect muscles in any part of the body, although it is most commonly observed in the leg muscles. It is particularly prevalent in individuals with cerebral palsy, where it affects approximately 80% of patients. Spasticity in children can lead to growth problems, painful and deformed joints, and disability. In individuals with cerebral palsy, spasticity may not be apparent in infancy but can become more evident as the child matures.
The management of spasticity requires careful consideration, as some patients rely on certain aspects of spasticity to maintain enough tone for functions such as standing or walking. Treatment options include physical therapy, medication, and botulinum toxin injections. Physical therapy focuses on lower extremity stretching and strengthening exercises, mobility training, and improving overall mental health. Oral medications are typically used in combination with other therapies and are reserved for cases where symptoms interfere with daily functioning or sleep. Botulinum toxin injections can be used to paralyze the spastic muscle, preventing it from contracting.
Selective dorsal rhizotomy (SDR) is a surgical procedure used to treat severe spasticity of the legs. It involves cutting selective nerve roots to rebalance the electrical signals sent to the spinal cord, thereby decreasing muscle stiffness while maintaining other functions. Another surgical option is the implantation of an ITB pump, which is indicated for patients with generalized spasticity who do not respond to more conservative treatments. Early identification and management of spasticity are crucial to prevent permanent loss of joint range and to improve patients' quality of life.

Muscle groups have decreased inhibition
Spasticity is a motor disorder that causes a velocity-dependent increase in muscle tone, resulting in muscle stiffness and spasms. It is characterised by involuntary, velocity-dependent muscle contractions that cause resistance to movement. This condition can vary in severity, ranging from mild feelings of muscle tightness to severe and painful stiffness and spasms. Spasticity can affect movement and speech, and in some cases, it may lead to immobility of joints.
When a muscle undergoes spasticity, it experiences a sudden increase in muscle tone, resulting in a velocity-dependent increase in muscle contractions. This is often referred to as "tightness" or "stiffness". The condition is typically caused by an insult to the central nervous system or motor neurons, which can be due to a primary condition such as degenerative disorders or secondary causes such as spinal cord injuries, brain trauma, or inflammatory conditions like multiple sclerosis. Spasticity can also occur as a result of congenital conditions or other factors affecting the brain, spinal cord, or nerves, disrupting the flow of signals between the muscles and the brain.
Muscle groups experiencing spasticity exhibit decreased inhibition, resulting in a loss of descending tonic or phasic excitatory and inhibitory inputs to the spinal motor apparatus. This leads to alterations in the segmental balance of excitatory and inhibitory control, denervation supersensitivity, and neuronal sprouting. The absence of inhibitory inputs contributes to the increased muscle contractions and resistance observed in spasticity.
The decreased inhibition in muscle groups during spasticity can have several consequences. It can lead to permanent joint deformities, increased risk of pressure ulcers and infections, interference with daily functions, and challenges with hygiene, comfort, and nursing care. Additionally, spasticity can cause contractures, which are permanent muscle contractions that further contribute to muscle stiffness and joint immobility.
Treating spasticity aims to relax the muscles, relieve pain and stiffness, and improve overall quality of life. A multidisciplinary team of healthcare professionals is often involved in managing spasticity, including neurologists, physiatrists, physical therapists, occupational therapists, speech and language pathologists, neurosurgeons, and orthopedic surgeons. Treatment options include physical therapy, medication, botulinum toxin injections, casting or bracing, and in severe cases, selective dorsal rhizotomy or surgical interventions. Early identification and management of spasticity are crucial to prevent further complications and improve patient outcomes.

Increased excitability of muscle spindles
Spasticity is a disruption in muscle movement patterns that causes certain muscles to contract all at once, affecting movement and speech. It can range from mild feelings of muscle tightness to severe painful, uncontrollable stiffness and spasms.
Spasticity is caused by damage or disruption to the area of the brain and spinal cord that control muscle and stretch reflexes. It is a symptom of certain neurological conditions.
Muscle spindles are delicate sensory receptors present in almost every muscle. They inform the central nervous system (CNS) about changes in the length of individual muscles and the speed of stretching. This information is used by the CNS to compute the position and movement of our extremities in space, which is essential for motor control, maintaining posture, and a stable gait.
Problems with muscle spindles can lead to abnormal muscle tone and spasticity. Increased excitability of muscle spindles can be caused by overactive input from gamma motor neurons or increased excitability at the central synapse, usually due to cortical damage and a loss of inhibitory impulses. This loss of inhibition leads to increased excitability. Spasticity may also be caused by problems with the Renshaw cells, which are interneurons that are stimulated by the alpha motor neuron and then, by a feedback mechanism, inhibit the alpha motor neuron, causing autoinhibition.
The recovery of muscle spindle sensitivity following stretching is promoted by isometric but not dynamic muscle contractions. Stretching can induce neural alterations, but these do not seem to have long-lasting effects. The inhibition of muscle spindle sensitivity is usually reversed when the stretched muscle contracts again due to α-γ co-activation.

It is often a symptom of neurological conditions and can range from mild to severe. While there is no cure for spasticity, various treatment options can help manage symptoms and improve quality of life. Treatment for spasticity typically involves a team of healthcare professionals with different specialties, including neurologists, physical therapists, and occupational therapists.
Physical Therapy
Physical therapy is a common treatment approach for spasticity, focusing on lower extremity stretching and strengthening exercises, as well as mobility training. This can help improve muscle flexibility, range of motion, coordination, and strength.
Occupational Therapy
Occupational therapy involves exercises targeting small muscle groups to enhance strength and coordination, enabling individuals to perform daily tasks more easily.
Medication
Oral medications are often used in conjunction with other therapies to manage spasticity. Skeletal muscle relaxants, such as baclofen and tizanidine, can be administered, especially for individuals with stroke or generalized spasticity. However, drug therapies can have adverse effects, and combinations of antispasticity drugs should be prescribed by specialists.
Botulinum Toxin Injections (Botox)
Botox injections can be used to selectively relax spastic muscles, improving comfort and function. These injections are typically considered when spasticity is localized to a few muscle groups and can be used alongside other treatments.
Selective Dorsal Rhizotomy (SDR)
SDR is a surgical procedure reserved for severe spasticity in the legs. It involves cutting selective nerve roots to rebalance electrical signals sent to the spinal cord, thereby reducing muscle stiffness.
Casting or Bracing
Temporary casts or braces can be used to prevent involuntary spasms and reduce muscle tightening.
Intrathecal Baclofen Therapy
In severe cases, a pump may be surgically placed in the abdomen to deliver a steady dose of baclofen directly to the spine.
