Spasticity is a term that comes up frequently in neurorehabilitation, but it’s rarely explained in a way that feels accessible or useful to the people who need to understand – the people living with it, as well as, family members and carers who provide daily support.
This guide aims to explain what spasticity is, why it happens, what it can look and feel like, how it’s managed, and how specialist rehabilitation at VIM Health can help. Our goal is to give you the knowledge and confidence to support yours or your loved one’s recovery, ask the right questions, and understand the treatment plan.
What Is Spasticity?
Spasticity is a condition in which certain muscles become abnormally tight, stiff, or resistant to movement. It’s caused by damage to the parts of the brain or spinal cord that control voluntary movement. When these areas are disrupted – whether by stroke, trauma, disease, or injury – the messages between the brain and the muscles become distorted, leading to an imbalance in muscle tone.
In simple terms, muscles that should relax during movement stay contracted. This can make movement difficult, painful, or in some cases impossible without support. Spasticity can be mild – a slight feeling of tightness – or severe, causing limbs to become fixed in abnormal positions.
It’s important to understand that spasticity is not a disease in itself. It’s a symptom – a consequence of underlying neurological damage. This distinction matters because it means spasticity can often be managed, reduced, and in many cases significantly improved with the right approach.
What Causes Spasticity?
Spasticity occurs when there is damage to the nerve pathways that carry signals from the brain and spinal cord to the muscles. Under normal circumstances, these pathways maintain a balance between muscle contraction and relaxation. When that balance is disrupted, muscles can become overactive.
The conditions most commonly associated with spasticity include:
- Stroke – spasticity is one of the most common complications following a stroke, often affecting one side of the body. It can develop within days, weeks, or months after the event.
- Spinal cord injury – damage to the spinal cord frequently results in spasticity below the level of the injury, affecting the legs, trunk, or all four limbs depending on the location and severity.
- Traumatic brain injury – depending on the area of the brain affected, spasticity can present in various patterns across the body.
- Multiple sclerosis (MS) – as MS damages the protective covering of nerve fibres, spasticity is a common and often fluctuating symptom.
- Cerebral palsy – spasticity is present from early life in many people with cerebral palsy, affecting muscle development and movement patterns.
Understanding the underlying cause helps guide the treatment approach. At VIM Health, our specialist neuro physiotherapists and occupational therapists are experienced in assessing and managing spasticity across all of these conditions.
What Does Spasticity Look and Feel Like?
You may be the first to notice changes in muscle tone or movement. Spasticity can present in many ways, and recognising the signs early can help ensure timely intervention.
Common Signs to Look For
- Muscles that feel unusually tight or rigid, particularly in the arms, legs, or trunk
- A limb that resists being moved or straightened by someone else
- Fingers that curl into a fist or a hand that is difficult to open
- A foot that turns inward or points downward (known as foot drop or equinovarus)
- Legs that cross or scissor when standing or transferring
- Sudden involuntary movements or muscle spasms, which may be painful
- Difficulty with everyday tasks such as dressing, bathing, or sitting comfortably
- Changes in posture or the way your loved one sits in their wheelchair
What Can Make Spasticity Worse?
Spasticity is not constant. It can fluctuate throughout the day and be influenced by a range of factors. Understanding these triggers can help support you more effectively.
- Pain – from any source, including pressure sores, urinary tract infections, constipation, or poorly fitting equipment
- Temperature changes – cold environments can increase muscle stiffness
- Fatigue – tiredness and overexertion often worsen spasticity
- Stress and anxiety – emotional distress can heighten muscle tone
- Positioning – sitting or lying in one position for too long without repositioning
- Illness or infection – even a mild cold can temporarily increase spasticity
If you notice a sudden increase in spasticity, it’s always worth considering whether there is an underlying trigger that needs addressing. Sometimes managing the trigger – such as treating an infection or adjusting a seating position – can reduce the spasticity without any change to the treatment plan.
Is Spasticity Always a Bad Thing?
This may seem like a surprising question, but the answer is no – not always. In some cases, a degree of spasticity can actually be helpful.
For example, increased tone in the legs can sometimes assist with standing transfers or provide stability when sitting. Some people find that their spasticity helps them maintain posture in a wheelchair or provides a sense of support in their limbs.
The key is whether the spasticity is functional or problematic. If it’s helping, it may be managed rather than reduced. If it’s causing pain, limiting movement, interfering with daily activities, or putting skin and joints at risk, then active treatment is needed.
This is why a thorough, individualised assessment is so important. At VIM Health, we don’t take a one-size-fits-all approach. Our team works closely with the client and their family to understand how spasticity is affecting their life and what level of intervention is appropriate.
How Is Spasticity Managed?
Spasticity management is not about a single treatment. It’s an ongoing process that combines several approaches, tailored to the individual. The goal is always to improve comfort, function, and quality of life.
Physiotherapy and Occupational Therapy
Specialist neuro physiotherapy and occupational therapy form the foundation of spasticity management. At VIM Health, our therapists use a range of techniques including:
- Sustained stretching – regular, prolonged stretching of affected muscles helps maintain length and reduce stiffness over time. This is something that carers and family members can be taught to assist with at home.
- Positioning and seating – how someone is positioned throughout the day has a direct impact on spasticity. Our occupational therapists assess seating, sleeping positions, and equipment to ensure optimal posture and tone management.
- Splinting and casting – custom-made splints or serial casts can be used to maintain muscle length, reduce contracture, and support functional hand or foot positions. Several of our therapists have specialist training in upper and lower limb splinting.
- Functional task practice – practising meaningful, goal-oriented tasks helps the brain re-learn movement patterns that work around or through the spasticity.
- Standing programmes – regular weight-bearing through standing frames or devices like the EasyStand Glider provides a sustained stretch to the muscles of the lower limbs and trunk.
Robot-Assisted and Technology-Led Therapy
At VIM Health, we combine hands-on therapy with advanced rehabilitation technology to enhance spasticity management:
- The Amadeo (Tyromotion) – provides precise, repetitive finger and hand exercises for people with spasticity affecting grip and fine motor control. The adaptive resistance responds to the individual’s tone, making it safe and effective.
- The THERA-Trainer Lyra – supports body-weight gait training, allowing people with lower limb spasticity to practise stepping in a controlled, repetitive way that promotes neuroplasticity.
- FES Cycling – functional electrical stimulation activates weakened muscles in a coordinated pattern, helping to reduce tone while building strength and cardiovascular fitness.
- The Bioness Go – a wearable FES device that supports walking by stimulating the muscles responsible for lifting the foot, particularly useful for spasticity-related foot drop.
These technologies allow for a level of intensity and repetition that manual therapy alone cannot achieve, and they generate objective data that helps our team monitor changes in tone and function over time.
Botulinum Toxin Injections
Botulinum toxin (commonly known as Botox) is widely used in the management of focal spasticity. It works by temporarily blocking the nerve signals that cause muscles to contract excessively, creating a window of reduced tone that typically lasts around three to four months.
What’s important to understand is that botulinum toxin alone is not a complete treatment. The real value comes from the intensive rehabilitation that follows the injection. During the window of reduced tone, the muscles can be stretched more effectively, range of motion can be improved, and functional gains can be made that might not be possible when spasticity is at its peak.
At VIM Health, we work closely with consultants who administer botulinum toxin and provide the follow-up therapy that maximises the benefit of each injection cycle. This coordinated approach is critical to achieving lasting results.
Medication
Oral medications such as baclofen, tizanidine, and dantrolene are sometimes prescribed to manage spasticity. These can be effective at reducing overall muscle tone, but they work on the whole body rather than targeting specific muscles, which means they can sometimes cause unwanted side effects such as drowsiness, weakness, or fatigue.
Medication decisions are made by the medical team, and at VIM Health we work alongside prescribers to ensure that any medication changes are reflected in the rehabilitation plan. If you are medication for spasticity and you notice changes – either improvements or side effects – it’s always worth mentioning this to your therapist and doctor.
How You Can Help at Home
If you are a family member or carer assisting someone with spasticity, you play an incredibly important role in spasticity management. Much of what happens outside of therapy sessions – the positioning, the stretching, the daily routines – can have a significant impact on how well spasticity is controlled.
Practical Things You Can Do
- Learn the stretching programme – ask the therapy team to show you which stretches are important and how to perform them safely. Consistency is key, even if each session is short.
- Pay attention to positioning – ensure the person you are assisting is positioned well in their wheelchair, bed, or chair. Small adjustments can make a big difference to comfort and tone.
- Monitor for triggers – keep an eye out for things that seem to make the spasticity worse, such as pain, illness, cold, or stress, so that they can communicate these to the therapy team.
- Encourage movement – where safe to do so, active participation supports neuroplasticity.
- Look after the skin – spasticity can increase the risk of pressure sores, particularly if limbs are held in fixed positions. Check the skin regularly, especially around bony areas.
- Ask questions – The therapy team are there to support you and understanding the treatment plan helps you contribute to it.
When to Seek Specialist Help
Spasticity can change over time. It may develop gradually after an injury or illness, or it may worsen suddenly due to a new trigger. There are certain situations where seeking specialist assessment is particularly important:
- Spasticity is new or has recently changed in severity or pattern
- Pain associated with spasticity is not well controlled
- Spasticity is limiting your loved one’s ability to participate in daily activities or rehabilitation
- Contractures are developing – joints are becoming fixed in abnormal positions
- Current management strategies are no longer working effectively
- You are considering botulinum toxin injections and need specialist therapy support afterwards
- You have recently been discharged from NHS rehabilitation but spasticity remains a significant issue
In all of these situations, a specialist assessment can help determine the best course of action. At VIM Health, we offer comprehensive spasticity assessments carried out by experienced neuro physiotherapists and occupational therapists, using both clinical observation and technology-generated data to build a detailed picture.
