Dystonia: What Is It and How Can Physiotherapy Help?
Dystonia is a neurological movement disorder that can make movement feel unpredictable, uncomfortable and difficult to control. But with the right diagnosis and a personalised treatment approach, there are ways to manage symptoms and improve function.
Dystonia is a relatively uncommon neurological condition, and it can look very different from one person to another. Some people experience abnormal postures in one part of the body, while others have involuntary movements affecting several areas.
For some people, symptoms may be present most of the time. For others, dystonia may only appear during particular activities, such as writing, playing an instrument, walking or running.
What is dystonia?
Dystonia is a neurological movement disorder characterised by involuntary, patterned movements or postures. Movements may be sustained or intermittent and can have a twisting, tremulous or jerky quality. They are often brought on or made worse by voluntary movement.
Dystonia happens because the brain's movement-control systems are not regulating movement normally. It is not simply a problem with the muscles themselves.
Dystonia can affect almost any part of the body, including the:
neck and shoulders
eyes, eyelids, face and jaw
voice
hands and arms
legs and feet
trunk
Symptoms can include abnormal postures, repetitive movements, muscle spasms, tremor, pain and difficulty performing particular movements.
Some people also notice a sensory trick, where a light touch or particular movement temporarily reduces the dystonic posture or movement.
What are the different types of dystonia?
There are many different types of dystonia. Dystonia can be classified according to which parts of the body are affected, as well as whether it occurs on its own or as part of another neurological condition.
Focal dystonia: affects one body region such as cervical dystonia.
Task-specific dystonia: Task-specific dystonia occurs during a particular activity. For example, a person may develop dystonia only when writing, playing a musical instrument or performing another highly skilled repetitive movement. Writer's cramp and musician's dystonia are examples.
Segmental, multifocal and generalised dystonia: Dystonia can also affect more than one area:
Segmental dystonia affects two or more neighbouring body regions.
Multifocal dystonia affects two or more non-neighbouring body regions.
Generalised dystonia affects the trunk and at least two other areas of the body.
Hemidystonia affects multiple areas on one side of the body.
Dystonia can also occur as part of another neurological or metabolic condition, following certain types of brain injury, or as a result of medication exposure.
How is dystonia treated?
There is currently no single treatment that works for everyone with dystonia. Management is individualised according to the type of dystonia, the body areas affected, the underlying cause and the person's goals.
Treatment may include:
medication
botulinum toxin injections
physiotherapy and occupational therapy
speech and language therapy where appropriate
psychological support where needed
Many people benefit from a combination of treatments, rather than relying on one treatment alone.
Botox and dystonia
Botulinum toxin injections, commonly known by brand names such as Botox®, are an established treatment for several forms of dystonia.
Botulinum toxin is injected into selected muscles to temporarily reduce excessive muscle activity. This can reduce abnormal postures, involuntary movements and pain in the muscles being treated. The effects are temporary, so injections generally need to be repeated at intervals determined by the treating medical team.
Botulinum toxin is particularly useful when dystonia is concentrated in specific muscles, such as in cervical dystonia or some forms of limb dystonia.
Importantly, Botox does not retrain movement by itself. Reducing excessive muscle activity can create an opportunity to work on movement, function and physical capacity through rehabilitation.
This is where physiotherapy can become an important part of the wider treatment plan.
How can physiotherapy help with dystonia?
Physiotherapy for dystonia is not simply about stretching tight muscles or strengthening weak ones.
The approach needs to be individualised to the person's dystonia, movement pattern, symptoms and functional goals. Physiotherapy may focus on:
Movement retraining: Helping you find more efficient and functional ways of moving while considering how your dystonia responds to different movements, positions, tasks and sensory cues.
Maintaining movement and flexibility: Dystonia can lead to sustained abnormal postures and reduced movement in some people. Appropriate movement and positioning strategies may help maintain joint mobility and physical function.
Strength and physical conditioning: Exercise can be adapted to maintain general strength, cardiovascular fitness and physical capacity without unnecessarily aggravating dystonic symptoms.
Pain management: Dystonia can be painful, particularly when muscles are repeatedly working in abnormal positions. Rehabilitation may include movement strategies, positioning, exercise and education to help manage pain and physical discomfort.
Function and everyday activities: Treatment should ultimately relate back to what matters to you — whether that is walking more comfortably, returning to work, exercising, writing, playing music or managing everyday activities more easily.
Physiotherapy alongside Botox
Physiotherapy and botulinum toxin complement each other. After an injection, reducing excessive activity in a targeted muscle may make it easier to practise a movement or activity that was previously difficult. Physiotherapy can then focus on using that change to support function, movement quality and participation.
The exact timing and approach will depend on the individual, the muscles treated and the goals of rehabilitation. Research and clinical guidance support physiotherapy as an important part of multidisciplinary dystonia management, including alongside botulinum toxin treatment.
The aim is not to "exercise the dystonia away". Instead, rehabilitation works alongside medical treatment to help you make the most of the movement and function that are available.
Living with dystonia
Dystonia can be frustrating, particularly when movements change depending on the task, environment, fatigue or other factors.
Finding the right diagnosis and treatment team can make an important difference. For some people, the goal may be reducing pain or involuntary movement. For others, it may be maintaining mobility, returning to a particular activity or finding strategies that make everyday life easier.
There is no single rehabilitation programme for dystonia. Your treatment should reflect your individual movement pattern, symptoms, goals and wider medical management.
How The Rehab Team can help
At The Rehab Team, neurological rehabilitation is what we do every day. Our Neurological Physiotherapists provide individualised rehabilitation for people living with dystonia, working alongside your medical treatment and wider healthcare team where appropriate.
Physiotherapy may be particularly useful for managing movement, maintaining physical function, improving mobility and helping you work towards the activities that are important to you.
If you are receiving botulinum toxin treatment for dystonia, physiotherapy can also be used alongside your injections to help translate changes in muscle activity into meaningful movement and functional goals.
We provide in-home neurological physiotherapy throughout Tauranga, Papamoa and Mount Maunganui. Contact The Rehab Team to discuss whether neurological physiotherapy may be appropriate for you.
