Spasticity assessment and management
Assessing muscle stiffness and spasms after a brain, spinal or nerve problem, and managing it with a tailored plan — usually only when the spasticity is causing problems.
✓ Medically reviewed by a GMC-registered consultant · last reviewed September 2026 · next review September 2027 · how we review
In short
- Spasticity is muscle stiffness or spasms from a brain or spinal problem; it is treated mainly when it causes problems, not just because it is present.
- Sometimes stiffness is useful (for example to help standing), so treatment is targeted to your goals.
- Management is layered: remove aggravating factors first, then physical approaches, then medicines or targeted injections as needed.
- The aim is better comfort and function — not a cure for the underlying condition; physical therapy is central to making treatments work.
A plain-English summary. The detail — including risks and recovery — is below.

What is spasticity assessment and management?
Spasticity is increased muscle stiffness, tightness or spasms caused by a problem affecting the brain or spinal cord — for example after a stroke, brain or spinal injury, or with multiple sclerosis or cerebral palsy. The muscles can feel tight, pull a limb into an awkward position, jerk into spasm, or make movement and care harder.
Assessment means working out which muscles are affected, how the stiffness affects you, and what is making it worse (such as pain, infection, a full bladder, constipation or poor positioning). Management means a tailored plan to ease the problems it causes and protect movement and comfort.
A very important principle: not all spasticity needs treating. Sometimes the stiffness actually helps — for example keeping a leg firm enough to stand or transfer. Treatment is generally aimed at spasticity that is causing problems, such as pain, difficulty with care or dressing, poor positioning, or limiting useful movement.
Management is usually team-led and multi-layered: first treating anything that aggravates it, then physical approaches such as stretching, positioning, splinting and therapy, then medicines or targeted injections where appropriate. The goal is to improve comfort and function, not to 'cure' the underlying condition.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Oral medicines versus targeted injections
| Oral medicines | Targeted injections | |
|---|---|---|
| Best for | Widespread stiffness | Stiffness in a few specific muscles |
| How it works | Reduces tone all over | Relaxes the injected muscles |
| Main downside | Drowsiness, general weakness | Wears off; needs repeating; local weakness |
| Used with therapy? | Yes | Yes — therapy is essential |
These approaches are often combined. The right mix depends on which muscles are affected, your goals and how you respond.
Preparing for your treatment
- Bring a list of medicines and doses, and note any allergies.
- Bring relevant scans, letters and details of your condition and previous spasticity treatments.
- Note when the stiffness or spasms are worst, what triggers them, and how they affect daily life.
- Think about your goals — for example easier washing and dressing, less pain, better positioning or improved walking.
- Mention any recent infections, constipation, bladder problems or skin issues, as these can worsen spasticity.
- Bring a family member or carer if helpful, especially if they help with your care.
- Write down your questions.
What happens
The specialist asks how the stiffness and spasms affect you and examines the muscles and joints, checking tone, range of movement, posture and how you move and manage tasks. Recognised scales may be used to measure stiffness so change can be tracked.
They look for anything aggravating the spasticity — pain, infection, constipation, a full bladder, pressure areas or poor positioning — because treating these often helps. Together you agree realistic goals.
A plan is then tailored to you. It usually starts with physical management and any aggravating factors, and may add oral medicines, targeted injections such as botulinum toxin or a nerve block, or referral for specialist options such as an intrathecal baclofen pump. Therapy is built in throughout, and you are reviewed to see whether goals are being met.
Is this treatment right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Spasticity that is helping you (for example supporting standing or transfers) may be better left untreated or treated very cautiously.
- A fixed contracture — a permanently shortened muscle or joint — will not respond to muscle-relaxing treatment and needs a different approach.
- If a treatable cause such as infection, constipation or pain is driving the spasticity, that should be addressed first.
- Aggressive blanket treatment to remove all tone is rarely appropriate; treatment should be targeted to goals.
Delay or rearrange if…
- You have an active infection, constipation, a full bladder or a pressure sore that may be worsening the spasticity.
- Your neurological condition is changing rapidly and needs review first.
- Goals have not been agreed, so it is unclear what treatment should achieve.
- You are pregnant or breastfeeding, or there is another reason a specific medicine or injection should wait until reviewed.
Alternatives to discuss
- Physical management alone (stretching, positioning, splinting, therapy) for milder problems.
- Treating aggravating factors as the first and sometimes only step.
- Oral medicines for widespread stiffness, or targeted injections for focal stiffness.
- Specialist intrathecal baclofen pump assessment for severe, widespread spasticity.
- No active treatment if the spasticity is mild or useful, with review if it changes.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Less pain and discomfort from tight muscles and spasms.
- Easier washing, dressing, positioning and care.
- Better posture, seating and comfort.
- Protection of joint movement and prevention of fixed contractures where possible.
- For some, improved use of a limb or easier walking.
- A clear, goal-based plan rather than piecemeal treatment.
Risks & complications
- Oral medicines can cause drowsiness, dizziness or general weakness.
- Stretching and therapy take ongoing effort.
- Targeted injections cause temporary effects that wear off and need repeating.
- Not every goal is fully achieved, so the plan may need adjusting.
- Too much muscle relaxation, making a limb feel weak or less useful.
- Skin or pressure problems if positioning is not maintained.
- Side effects from medicines that mean a change of treatment.
- Disappointment if expectations were higher than what is realistic.
- Serious problems are uncommon and depend on the specific treatment used — for example complications related to an intrathecal baclofen pump, which are managed by a specialist team.
- A fixed contracture (a permanently shortened muscle or joint) will not respond to muscle-relaxing treatment and may need a different approach.
The main pitfalls are treating spasticity that was actually helping, expecting medicines to 'cure' the underlying condition, or using injections or tablets without the physical therapy that makes them work. Tell your team your goals clearly, and ask what each treatment can realistically achieve, how long it lasts, and what the plan is if it does not help.
Published figures to discuss
Outcomes vary widely and we will not invent figures. How well spasticity responds depends on the underlying condition, which muscles are involved, how long it has been present, whether contractures have formed, and how well physical therapy is combined with treatment. Side-effect risk depends on the specific treatment chosen. A good result is judged against your agreed goals rather than a single percentage.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Contracture and pain if spasticity is untreated | Condition- and time-dependent | Long-standing spasticity can shorten muscles and impair hygiene, comfort, sleep and mobility. | Guide sourcesClinical context |
| Tone reduction worsens function | Recognised | Some people rely on tone for standing, transfers or grip, so treatment goals must be functional. | Guide sourcesClinical context |
| Medication side effects | Drug-dependent | Oral baclofen, tizanidine and other medicines can cause sleepiness, weakness, dizziness or liver/interaction issues. | Stroke Association — Spasticity and contracturesstroke.org.ukSource-linked context |
| Injection or splint without therapy plan | Common failure mode | Best results usually combine stretching, strengthening, positioning, orthotics and goal review. | Stroke Association — Spasticity and contracturesstroke.org.ukSource-linked context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no recovery from the assessment itself. 'Afterwards' depends on the plan you agree: physical management is ongoing, oral medicines are adjusted over days to weeks, and injections work over days with effects lasting a few months.
- Stiffness easing gradually rather than disappearing completely.
- Some drowsiness when starting or increasing oral medicines.
- Needing to keep up stretches, positioning and therapy for lasting benefit.
- Injection effects building over days and fading over a few months.
- The plan being fine-tuned over several reviews.
Aftercare
- Keep up the stretches, positioning, seating and therapy advised — these make treatments work.
- Take any medicines as prescribed and report drowsiness, weakness or other side effects.
- Watch for and treat aggravating factors early: infections, constipation, full bladder, skin pressure or pain.
- Use splints, braces or equipment as advised.
- Keep a note of what helps and what does not for your review.
- Involve carers in positioning and the plan where relevant.
- Contact your team if stiffness suddenly worsens or new problems appear.
- Your goals written down
- An up-to-date list of medicines and allergies
- Relevant scans, letters and previous treatment details
- Notes on triggers and when stiffness is worst
- Any infection, bladder, bowel or skin problems flagged
- Splints or equipment you already use brought along
- A carer involved if helpful, and your questions listed
⚠ Get urgent help if…
- A sudden, marked increase in spasticity or spasms — this can be a sign of a urine infection, constipation, a pressure sore or other problem needing attention.
- Signs of infection: fever, a hot swollen limb, burning on passing urine, or a new pressure sore.
- New or worsening pain, or a limb becoming stuck in a fixed position.
- With an intrathecal baclofen pump: sudden severe stiffness, fever, itch or drowsiness can signal a pump problem — seek urgent specialist advice.
- Excessive weakness, severe drowsiness or breathing problems after starting or increasing medicines.
- New numbness, bladder or bowel changes, or rapidly worsening function — seek urgent help.
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A good outcome is meeting the goals you set — for example less pain, easier care, better positioning, or more useful movement — while keeping any helpful muscle tone. Recognised scales help show whether stiffness has changed, but the real test is whether daily life is better.
Management does not cure the underlying brain or spinal condition, and not all stiffness can or should be removed. Some treatments wear off and need repeating, and fixed contractures need different approaches. Honest, realistic goals are central to a good result.
Spasticity is usually a long-term issue, so management is ongoing and reviewed as your condition changes. Physical approaches need to be kept up. Oral medicines may be adjusted over time, and targeted injections wear off after a few months and are repeated when helpful. Specialist options such as a pump need long-term specialist follow-up.
Related tests, treatments or support
Spasticity management is part of wider neurorehabilitation and works best combined with physiotherapy and occupational therapy. Botulinum toxin injections and nerve blocks for specific muscles, oral medicines for widespread stiffness, and good bladder, bowel, skin and pain care are often used together. Treating aggravating factors is part of the same plan.
Follow-up & long-term care
You will be reviewed to check whether goals are being met and to adjust the plan. Oral medicines are titrated with review; injection treatments are reassessed and repeated when appropriate; pumps need regular specialist refills and checks. Your GP and team stay informed and can help between reviews.
- Ongoing stretching, positioning, seating and therapy.
- Reviewing and adjusting oral medicines.
- Repeating targeted injections when their effect wears off, if helpful.
- Regular checks and refills for an intrathecal baclofen pump.
- Prompt treatment of infections, constipation and skin problems that worsen spasticity.
- Periodic reassessment of goals and equipment.
Repeat, follow-on and what comes next
- Plans are routinely adjusted: doses changed, treatments switched or combined, or injections repeated as effects wear off.
- Targeted injections are repeated, typically not more often than around every three months, when they continue to help.
- If a treatment does not meet goals, the answer is reassessment and a change of approach.
- Severe cases may be escalated to specialist options such as an intrathecal baclofen pump.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A clear, goal-based written plan with therapy built in.
- Recognised measures to track whether stiffness and function are improving.
- Defined review points and a plan for repeating or adjusting treatment.
- Advice on managing aggravating factors and warning signs.
- A named contact and joined-up team and GP communication.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Length and complexity of the assessment, and whether a team is involved.
- Which treatments are used — physical management, oral medicines, injections or specialist pump therapy.
- Number of injection sessions and whether ultrasound or stimulation guidance is used.
- Therapy input needed alongside treatment.
- Frequency of review and how often injections need repeating.
- Equipment such as splints, seating or braces, usually charged separately.
- The fee for assessment and for each treatment or injection session.
- What is included in the plan and how therapy fits in.
- The cost and frequency of repeat injections, where used.
- Whether a written plan and a letter to your GP are included.
- The cost of equipment such as splints or seating, usually charged separately.
- How follow-up and review are arranged and charged.
- What happens, and any cost, if a treatment does not help and an alternative is needed.
On the NHS? Spasticity assessment and management is available on the NHS by referral when clinically indicated; private care is generally used for faster access, a second opinion or more choice rather than because it is unavailable on the NHS.

Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Treating spasticity that was actually useful, leaving a limb weaker or less functional.
- Implying medicines or injections will cure the underlying condition.
- Using injections or tablets without the physical therapy that makes them effective.
- Not explaining that injection effects wear off and need repeating.
- Not agreeing clear goals or a plan for if treatment does not help.
Marketing red flags
- Promises to 'cure' spasticity or the underlying condition.
- Pushing injections or expensive packages without physical therapy or clear goals.
- Aggressive treatment of all stiffness regardless of whether it helps you.
- No mention of repeat treatment, side effects or realistic limits.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
