Spasticity Management in Rehabilitation: Stretching, Splints, and Injections

Spasticity is increased muscle stiffness that can affect movement, comfort, hygiene, and daily activities after conditions such as stroke, brain injury, spinal cord injury, cerebral palsy, or multiple sclerosis. Rehabilitation combines stretching, positioning, splints, targeted injections, exercise, and medication when needed to reduce complications and support meaningful function.

Overview

Spasticity is a movement problem caused by changes in the way the brain or spinal cord communicates with muscles. It often feels like tightness, stiffness, pulling, or involuntary muscle resistance when a limb is moved. Some people notice spasms, clenched hands, pointed toes, scissoring of the legs, or difficulty relaxing a muscle. Spasticity can appear after stroke, traumatic brain injury, spinal cord injury, cerebral palsy, multiple sclerosis, and other neurological conditions.

In rehabilitation, spasticity management is not simply about making muscles looser. The aim is to improve comfort, movement, posture, skin care, hygiene, sleep, participation, and independence. In some cases, a certain amount of muscle tone may help a person stand, transfer, or stabilize a limb. For this reason, treatment should be individualized rather than automatically reducing all stiffness.

A good spasticity plan usually combines several approaches. Stretching, positioning, strengthening, task-specific practice, splints, braces, and injections may all have a role. The most appropriate treatment depends on the cause of spasticity, which muscles are involved, how long it has been present, and what the person wants to achieve in daily life.

Symptoms and Daily Impact

Spasticity can be mild and occasional, or it can significantly affect daily routines. Common signs include muscle tightness, resistance during movement, sudden spasms, jerking, cramps, difficulty opening the hand, difficulty placing the foot flat, and reduced range of motion at a joint. Symptoms may be worse with fatigue, stress, pain, infection, constipation, poor sleep, or changes in posture.

The impact depends on which muscles are affected. Spasticity in the calf may cause toe walking, ankle turning, or difficulty clearing the foot during walking. Tightness in the hip and thigh muscles may make sitting, transferring, or personal care more difficult. In the arm, spasticity may pull the elbow, wrist, or fingers into a flexed position, making dressing, washing the palm, or using the hand harder.

Spasticity may also contribute to pain, pressure areas, joint stiffness, and contractures if a limb remains in one position for a long time. A contracture means the muscles, tendons, or joint tissues have shortened, limiting movement even when the nervous system is relaxed. Early rehabilitation aims to preserve flexibility and function before fixed stiffness develops.

Causes and Triggers

Spasticity develops when pathways in the central nervous system that normally regulate muscle tone are disrupted. After a stroke or brain injury, the balance between signals that activate and calm muscles may change. In spinal cord injury or multiple sclerosis, nerve pathways between the brain, spinal cord, and muscles may be interrupted or irritated. The result is increased muscle response to stretch and movement.

Even when the underlying neurological condition is stable, spasticity can fluctuate. Common triggers include urinary tract infection, skin irritation, pressure injuries, ingrown toenails, constipation, pain, tight clothing, poorly fitting braces, emotional stress, sudden temperature changes, and fatigue. Identifying triggers is an important part of management because treating the trigger may reduce stiffness without adding medication.

Risk of long-term stiffness increases when a limb is not moved through its available range, when weakness limits active movement, or when a person spends long periods in one posture. Rehabilitation therefore focuses on safe movement, positioning, and regular reassessment. The goal is to support the nervous system, muscles, joints, skin, and daily function together.

Assessment and Goal Setting

Spasticity assessment begins with a detailed history and physical examination. The rehabilitation team may ask when stiffness occurs, what makes it better or worse, whether spasms are painful, and how symptoms affect walking, dressing, hygiene, transfers, sleep, caregiving, or therapy. The clinician will also check strength, sensation, joint range, skin condition, posture, balance, and voluntary control.

Several clinical scales can help describe muscle tone, spasm frequency, pain, and function, but no single measurement captures the whole picture. For example, a person may have noticeable stiffness but still use it to stand, while another person may have mild stiffness that causes painful hand clenching. This is why the patient’s priorities and real-life goals are central to treatment planning.

Goals should be specific and practical. Examples include opening the hand enough for palm hygiene, placing the heel more comfortably in a shoe, reducing painful night spasms, improving wheelchair seating, making dressing easier, or improving the pattern of walking. Clear goals also help the team decide whether stretching, splints, injections, medication, or other interventions are working.

Stretching, Positioning, and Exercise

Stretching is one of the most common parts of spasticity rehabilitation. It aims to maintain or improve range of motion, reduce discomfort, and help prevent shortening of muscles and soft tissues. Stretching is usually performed slowly and gently, avoiding bouncing or forcing the limb. A therapist can teach the safest method, how long to hold a position, and how to adapt the stretch for home practice.

Positioning is equally important. Proper sitting, lying, wheelchair alignment, and limb support can reduce prolonged postures that encourage tightness. For example, the shoulder and hand may need support after stroke, or the ankle may need positioning to avoid persistent toe-pointing. Pillows, cushions, standing frames, tilt tables, and seating systems may be considered depending on the person’s condition and tolerance.

Exercise should not be limited to passive stretching. Active movement, strengthening of weaker muscles, balance training, gait training, and task-specific practice can improve control and reduce the functional impact of spasticity. Some people benefit from treadmill training, cycling, aquatic therapy, robotic-assisted therapy, or electrical stimulation as part of a broader plan. The right choice depends on safety, goals, endurance, and neurological recovery potential.

• Move slowly and stop if stretching causes sharp pain.
• Use a routine that fits daily life, such as after bathing or before bedtime.
• Combine flexibility work with strengthening and functional practice when possible.
• Ask a therapist to review technique if stiffness changes or pain develops.

Splints, Braces, and Orthoses

Splints and orthoses are devices used to support alignment, maintain muscle length, protect joints, or improve function. They may be used for the hand, wrist, elbow, ankle, knee, or other joints. A wrist-hand splint may help keep the hand in a safer position for hygiene and comfort, while an ankle-foot orthosis may help foot clearance and stability during walking. Some devices are worn at rest, and others are used during standing or walking.

Splints are most helpful when they are carefully fitted and linked to a clear goal. Wearing schedules vary and should be individualized. Skin checks are essential, especially for people with reduced sensation, swelling, fragile skin, or circulation problems. Redness that does not fade, pain, numbness, pressure marks, or increased spasms may mean the device needs adjustment.

There are different types of splints, including static splints that hold a position, dynamic splints that provide gentle movement or tension, and serial casts that gradually change joint position over time. Serial casting may be considered for selected patients with significant tightness, often alongside therapy and sometimes after injections. Any splinting program should be reviewed regularly because needs can change with recovery, growth in children, weight changes, or changes in muscle tone.

Injections and Medical Treatments

When spasticity is focused in particular muscles, injections may be considered. Botulinum toxin injections are commonly used for focal spasticity, such as a clenched fist, flexed elbow, tight calf, or inward-turning foot. The medicine is injected into selected overactive muscles to temporarily reduce excessive muscle activity. Effects develop gradually and are typically combined with therapy, stretching, splinting, and functional training to make the most of the treatment window.

Other focal treatments may include nerve or motor point blocks using agents such as phenol or alcohol in selected cases. These are usually performed by clinicians experienced in spasticity management and may be guided by ultrasound, electrical stimulation, or anatomy-based techniques. The choice of injection depends on the pattern of spasticity, treatment goals, medical history, and potential side effects.

For more widespread spasticity, oral medicines may be considered. These can reduce tone but may also cause sleepiness, weakness, dizziness, or other side effects in some people. In severe generalized spasticity that does not respond to other measures, intrathecal baclofen therapy may be discussed; this involves delivering medication near the spinal cord through an implanted pump. Surgery, such as tendon lengthening or orthopedic correction, is reserved for selected cases where fixed contracture or deformity limits care or function.

Medical treatment works best when it is integrated with rehabilitation. Reducing tone without training may not automatically improve movement. After injections or medication changes, therapy often focuses on stretching, strengthening, motor control, splint adjustment, gait practice, hand training, or caregiver education depending on the goals.

Prevention, Self-care, and When to See a Doctor

People living with spasticity can often reduce complications by following a consistent self-care plan. This may include daily range-of-motion exercises, safe positioning, regular skin checks, hydration, bowel and bladder routines, comfortable footwear, and avoiding prolonged postures. Caregivers may be taught safe handling techniques so that stretching and transfers do not cause pain or shoulder strain.

It is important to seek medical review if spasticity appears suddenly, becomes noticeably worse, causes new pain, affects sleep, interferes with hygiene, leads to skin redness or pressure areas, or makes walking and transfers less safe. A sudden increase can sometimes reflect a treatable trigger such as infection, constipation, injury, or an ill-fitting brace. Regular follow-up is also useful after injections, splint changes, medication adjustments, or changes in mobility.

A multidisciplinary rehabilitation team may include a physiatrist, neurologist, physiotherapist, occupational therapist, orthotist, rehabilitation nurse, and, when needed, orthopedic or neurosurgical specialists. Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat spasticity and related neurological rehabilitation needs for international patients. Any person considering treatment should consult a qualified doctor for an individualized assessment and plan.

Frequently asked questions

Can spasticity be cured completely?

Spasticity is usually related to an underlying neurological condition, so it may not disappear completely. However, it can often be managed well enough to improve comfort, care, movement, and participation. The most effective plan is individualized and reviewed over time.

Is stretching enough to manage spasticity?

Stretching is important, especially for maintaining range of motion and comfort, but it is often only one part of treatment. Many people also need strengthening, positioning, splints, task-specific practice, or medical treatments. A therapist can help design a safe program that matches the person’s goals.

Do splints weaken muscles?

A properly prescribed splint is intended to support alignment, protect joints, or maintain soft tissue length, not replace active movement. Problems can occur if a splint is poorly fitted, worn for the wrong schedule, or not combined with exercise when appropriate. Regular review helps ensure the splint remains useful and safe.

How long do botulinum toxin injections for spasticity last?

The effect is temporary and varies from person to person. Benefits usually develop gradually after injection and then wear off over time, so repeat treatment may be considered if goals are met and it remains appropriate. Therapy and splinting during the active period can help improve outcomes.

Are spasticity injections painful?

Most people tolerate injections well, although there may be brief discomfort at the injection sites. Clinicians may use techniques such as careful positioning, small needles, ultrasound guidance, or other comfort measures when appropriate. Patients should discuss concerns and previous experiences with the treating doctor.

Can exercise make spasticity worse?

Exercise is generally helpful when it is appropriate to the person’s condition and performed safely. Overexertion, poor positioning, pain, or fatigue can temporarily increase stiffness in some people. A rehabilitation professional can adjust intensity, technique, and rest periods to support progress without unnecessary discomfort.

When should a person be assessed by a spasticity specialist?

Assessment is recommended when stiffness causes pain, limits hygiene, affects walking, interferes with sleep, or makes care and transfers difficult. It is also helpful when splints are uncomfortable, contractures are developing, or previous treatments are not meeting goals. Early review can prevent complications and improve long-term planning.
