Muscle spasticity is a symptom of certain neurological conditions, causing muscles to contract all at once and affecting movement and speech. It can be caused by damage to the brain, spinal cord, or motor nerves, and is commonly associated with conditions such as cerebral palsy and multiple sclerosis. Spasticity can vary in severity, ranging from mild muscle tightness to severe, painful, and uncontrollable stiffness. Treatment options include physical therapy, medication, botulinum toxin injections, and surgery, with the aim to improve comfort, mobility, and independence for patients.
Characteristics and Values
| Characteristics | Values |
|---|---|
| Definition | "Spasticity is a motor disorder characterised by a velocity-dependent increase in tonic stretch reflexes (muscle tone) with exaggerated tendon jerks, resulting from hyperexcitability of the stretch reflex, as one component of the upper motor neurone syndrome." |

Physical therapy
Spasticity is a symptom of certain neurological conditions, causing muscles to contract involuntarily and all at once, which can interfere with movement and speech. It is a velocity-dependent increase in muscle tone, meaning that the faster the muscle is moved or stretched, the greater the resistance to stretch. This creates an inability to stretch muscles or coordinate movements effectively.
The aims of physical interventions include facilitating neural activity in the damaged cerebral hemisphere and minimising changes in the viscoelastic properties of connective tissue muscles around the joints. Electromyography (EMG) biofeedback is a useful therapeutic tool for the rehabilitation of stroke patients, guiding patients to replicate correct muscle firing patterns. Other physical modalities include ultrasonography, electrical stimulation, and non-invasive low-frequency transcranial magnetic stimulation (TMS).

Medication
Baclofen is often considered the first-line treatment for spasticity, especially in adult spinal cord injuries (SCI). It works by restricting the influx of calcium into the neural receptors and increasing the influx of potassium, leading to a decrease in the number of messages nerve cells transmit. In more severe cases of spasticity, a pump can be surgically implanted in a person's abdomen to administer baclofen directly to the spinal fluid. This method, known as intrathecal baclofen (ITB) therapy, has been found to be very effective in treating spasticity in the lower extremities and reducing pain with a lower risk of drowsiness compared to oral baclofen.
Tizanidine is often used in conjunction with other oral drugs, such as baclofen, to enhance their effects. It decreases muscle tone by increasing the presynaptic inhibition of motor neurons, which in turn decreases the release of excitatory amino acids from spinal interneurons. Tizanidine has a short half-life, so frequent dosing is required for it to be effective. It is also associated with fewer muscle weakness side effects compared to other oral antispastic drugs.
Dantrolene sodium is unique among spasticity medications because it affects muscle fiber rather than nerve fiber. It reduces the release of calcium that usually occurs after muscle action.
Diazepam, clonazepam, and gabapentin are other oral medications that can be prescribed for spasticity. Diazepam depresses the central nervous system, while clonazepam is a benzodiazepine that can help relax muscles and reduce muscle tone.
In addition to oral medications, injectable medications can also be used to treat spasticity. Botulinum toxin injections, also known as Botox, are commonly used to treat spasticity in specific muscle groups. These injections help to relax the muscles, improve range of motion, and decrease muscle pain. Phenol injections, which involve injecting phenol directly into the fluid around the spinal cord, can be used for very severe spasms that do not respond to other treatments. However, it is important to note that phenol destroys the nerves that control sensation and movement, so it is only used when a person already has limited control in these areas.

Surgery
Spasticity is a velocity-dependent increase in muscle tone, causing uncontrolled, repetitive, involuntary contractions of skeletal muscles. It is a symptom of certain neurological conditions and can affect movement and speech. Spasticity can be incapacitating and cause significant pain and limited mobility, which can lead to a decreased quality of life and difficulty in maintaining personal care.
There are several non-surgical treatment options for spasticity, including physical therapy, medication, and botulinum toxin injections. However, in more severe cases, surgery may be required to correct spasticity. Surgical treatments for spasticity include:
Intrathecal Baclofen (ITB) Therapy
This treatment involves surgically placing a pump in the patient's abdomen that releases a steady dose of the medication baclofen directly into the spinal fluid through a catheter. This can significantly reduce spasticity and pain, with a lower risk of drowsiness compared to taking baclofen orally.
Selective Dorsal Rhizotomy (SDR)
SDR is a surgical procedure that rebalances the electrical signals sent to the spinal cord by cutting carefully selected nerve roots. This procedure is typically recommended for people with severe spasticity affecting their legs and those with cerebral palsy. By precisely cutting the problematic nerve roots, muscle stiffness can be decreased while maintaining other functions.
Orthopaedic Surgery
Orthopaedic surgery deals with treating the consequences of spasticity on muscles, bones, and connective tissue. This includes procedures such as contracture release, tendon transfer, osteotomy, and arthrodesis. Contracture release, the most commonly performed orthopaedic procedure, involves lengthening the Achilles tendon to correct "equinus" deformity. Tendon transfer involves moving the attachment point of a spastic muscle to improve function and prevent the muscle from pulling the joint into a deformed position. Osteotomy is used to correct deformities by removing a small wedge from a bone to allow it to be repositioned or reshaped. Arthrodesis, commonly performed on the bones in the ankle and foot, involves fusing bones together to limit the ability of a spastic muscle to pull the joint into an abnormal position.
Upper Limb Surgery
Upper limb surgery for severe spasticity can improve ease of care for individuals with acquired brain injuries. Surgical goals may include opening the fingers and thumb, achieving wrist stability, and releasing muscles around the elbow and shoulder. This type of surgery can significantly improve the patient's quality of life and reduce the burden on caregivers.

Management strategies
Physical Therapy:
- Physical therapy is a crucial aspect of managing muscle spasticity. It involves a range of exercises, including stretching and strengthening routines, to improve the patient's range of motion and mobility.
- Physical therapists may focus on lower extremity stretching to improve flexibility and joint modulation in the trunk and lower limbs.
- They also work on mobility training, which includes transfers, standing, and walking exercises to improve overall function.
- Robotic rehabilitation is a newer form of physical therapy that promotes guided neuroplasticity and helps patients develop a new functional pattern for moving and walking.
Occupational Therapy:
- Occupational therapy is often used in conjunction with physical therapy. It focuses on improving strength and coordination in small muscle groups, enabling patients to perform daily tasks more efficiently.
- This type of therapy is especially important for patients whose spasticity affects their upper limbs and fine motor skills.
Speech Therapy:
Speech therapy is indicated for patients whose spasticity has impacted their speech. This therapy helps improve articulation, fluency, and overall communication.
Casting or Bracing:
Casting or bracing are external supports that can be used to prevent involuntary spasms and reduce muscle tightening.
Medication:
- Oral medications are typically used in combination with other therapies when symptoms interfere with daily functioning or sleep.
- Botulinum toxin (Botox) injections can be used to paralyze specific spastic muscles, preventing them from contracting. These injections are placed carefully based on the pattern of spasticity and can provide relief for up to 12-16 weeks.
- Intrathecal Baclofen (ITB) Pump therapy is a more invasive option for extreme cases of spasticity. It involves surgically placing a pump in the patient's abdomen to release baclofen directly into the spinal fluid, significantly reducing spasticity and pain.
- Peripheral nerve blocks and botulinum toxin are local treatments that are proving useful in managing spasticity.
Multidisciplinary Team Approach:
- Managing muscle spasticity often requires a multidisciplinary team, including good nursing care, optimal posture education, and input from various healthcare professionals.
- This team may include a neurologist, physiatrist, advanced practice clinician, physical therapist, occupational therapist, speech and language pathologist, neurosurgeon, and orthopedic surgeon.
- Educating patients and their caregivers about proper positioning, skin care, and a regular bowel/bladder regimen is an important aspect of the multidisciplinary approach.

Non-medical treatments
Muscle spasticity is an increase in muscle tone that can cause discomfort, limit movement, and reduce function. It is typically related to a neurological condition, such as a stroke, spinal cord injury, cerebral palsy, multiple sclerosis, or brain injury. The condition may also occur due to a disorder or trauma, such as a tumour.
Injections are another non-surgical treatment option that has proven effective for many patients with spasticity. The most common injections are botulinum toxin type A and type B, which are used in minute amounts at specific sites to paralyze spastic muscles. Phenol injections are also used, which are a type of alcohol that, when injected in very small amounts, can prevent the transmission of too many nerve impulses without causing a lack of control or sensation.
In addition to injections and oral medications, other non-medical treatments for muscle spasticity include nerve blocks and surgery. Temporary nerve blocks can be used to manage spasticity, and surgery may be recommended for tendon release or to cut the nerve-muscle pathway. Deep brain stimulation is also being studied as a treatment option when other measures fail to bring relief.
