How Physiotherapy Can Help People Living With Borderline Personality Disorder and Complex Mental Health Challenges

Living with Borderline Personality Disorder (BPD) or other complex mental health conditions can feel all‑consuming. Emotional swings, distressing thoughts, and unstable relationships often sit at the center of the picture. Yet there is another part of the story that sometimes gets overlooked: the body.

Many people with BPD, complex trauma, or long-term mental health difficulties notice that their emotional distress is closely tied to physical sensations—tension, pain, restlessness, exhaustion, or even feeling disconnected from their body. This is where physiotherapy can quietly become a powerful part of a broader treatment plan.

This guide explores how physiotherapy can support, not replace, psychological and medical treatment for BPD and complex mental health conditions. It outlines what physiotherapy can realistically offer, what it cannot do, and how people might work with a physiotherapist in an integrated, safe, and compassionate way.

Understanding BPD and Complex Mental Health Conditions in a Body–Mind Context

What is Borderline Personality Disorder?

Borderline Personality Disorder is commonly described as a pattern of intense emotions, unstable self-image, and difficulties in relationships. People might experience:

• Strong fears of abandonment
• Rapid shifts in mood
• Impulsive behaviors
• Chronic feelings of emptiness
• Self-harm or suicidal thoughts
• A sense of inner chaos or instability

These experiences can be deeply painful and can influence every area of life—work, school, family, and physical health.

What Do “Complex Mental Health” Cases Mean?

The phrase complex mental health conditions is often used for people who:

• Live with more than one diagnosis (for example, BPD and PTSD, or BPD and an eating disorder)
• Have a history of repeated or long-term trauma
• Experience frequent crises, hospital admissions, or high levels of distress
• Find that standard, short-term treatments are not enough on their own

For many, these conditions are not only “in the mind.” They are felt throughout the whole body.

Why the Body Matters in Mental Health

People with BPD and other complex conditions often report:

• Muscle tension and pain (neck, shoulders, back, jaw)
• Headaches or migraines
• Digestive discomfort
• Sleep difficulties
• Fatigue or low physical stamina
• Feeling disconnected from the body (sometimes described as numb, unreal, or detached)

Emotions and body sensations are tightly linked. Stress can increase muscle tension; anxiety can affect breathing and heart rate; past trauma can be “held” in postures and movement habits. This is where physiotherapy enters the conversation.

What Physiotherapy Is (and What It Is Not)

The Role of Physiotherapy in Healthcare

Physiotherapy focuses on how the body moves and functions. Physiotherapists typically work with:

• Pain and musculoskeletal problems
• Injuries and rehabilitation
• Mobility difficulties and balance
• Recovery after surgery or illness
• Chronic conditions that affect movement, strength, or function

They use tools such as:

• Exercise therapy
• Hands-on (manual) therapy
• Movement retraining
• Breathing and posture education
• Self-management strategies

What Physiotherapy Does NOT Replace

For BPD and complex mental health issues, physiotherapy is:

• Not a replacement for psychotherapy (such as DBT, CBT, or trauma-focused therapy)
• Not a substitute for psychiatric care, medication management, or crisis services
• Not a cure for BPD or trauma

Instead, physiotherapy can be part of a wider, multidisciplinary approach, working alongside mental health professionals to support the person as a whole.

How Physiotherapy Can Support Care for BPD and Complex Mental Health

Physiotherapy does not directly treat the psychological core of BPD. However, it can indirectly support emotional and mental wellbeing by targeting the body-based aspects that often go hand in hand with it.

1. Managing Physical Pain and Tension

Many people living with long-term distress develop:

• Chronic muscle tension from constant “fight-or-flight” arousal
• Postural strain from guarding or bracing the body
• Repetitive strain from self-soothing movements or habits
• Pain linked to reduced movement or long periods of inactivity

A physiotherapist may:

• Assess posture, joint mobility, muscle strength, and movement patterns
• Offer gentle exercises to release tension and improve flexibility
• Suggest pacing and activity strategies to avoid overloading the body
• Use manual therapy or soft tissue techniques where appropriate

When pain and tension are eased, some people notice they have more emotional capacity to engage in therapy, daily routines, and relationships.

2. Supporting Self-Regulation Through the Body

Emotional regulation is a core challenge in BPD. Physiotherapy can support body-based self-regulation, such as:

• Breathing techniques to promote calmer breathing patterns and reduce sensations of breathlessness or tightness
• Grounding through movement, using gentle, repetitive actions to anchor attention in the present moment
• Postural awareness, helping people notice how different positions or movements affect emotional states

None of these replace psychological skills training, but they can complement strategies learned in therapy by giving a more concrete, physical focus.

3. Rebuilding a Sense of Safety and Control Over the Body

People with complex trauma or BPD often describe feeling:

• Unsafe in their own body
• Hyperaware of some sensations (like heart pounding) and disconnected from others
• Like their body is “not their own” or difficult to tolerate

A trauma-informed physiotherapy approach can help by:

• Introducing gentle, predictable movements
• Encouraging safe exploration of bodily sensations at a pace chosen by the person
• Providing clear choice, consent, and boundaries during sessions

Over time, some people find this supports:

• A more compassionate relationship with their body
• A greater sense of ownership and control over physical sensations
• Reduced fear of bodily responses like shaking, sweating, or tightness

4. Improving Sleep, Energy, and Daily Functioning

Sleep problems, exhaustion, and low motivation are common in complex mental health conditions. Physiotherapy can support:

• Sleep hygiene through movement: planning gentle activity during the day can sometimes improve sleep quality
• Graded activity: slowly building up movement and exercise levels without overwhelming the system
• Routine and structure: creating a predictable pattern of physical activity that can anchor the day

Better sleep and energy can enhance someone’s ability to participate in therapy and manage daily responsibilities.

5. Encouraging Healthy Movement and Exercise Habits

Movement can be difficult when:

• Motivation is low
• There is fear of pain or injury
• Exercise is tied to perfectionism or self-criticism
• There is a history of self-harm or harmful exercise patterns

Physiotherapists can help people find safe, sustainable, and flexible ways to move, such as:

• Light walking plans
• Gentle stretching routines
• Low-impact strength or balance exercises
• Short, manageable sessions tailored to current capacity

This kind of supported movement can help people reconnect with their body in a way that feels less punitive and more caring.

Working With the Nervous System: Why It Matters in BPD

The Stress Response and Body Reactions

Many people with BPD and complex trauma experience:

• Frequent activation of “fight, flight, or freeze” responses
• Sudden surges of panic, anger, or terror
• A sense of being constantly “on edge” or “about to explode”

These reactions show up physically as:

• Racing heart
• Shallow breathing
• Muscle tightness
• Shaking or restlessness
• Feeling hot, dizzy, or disconnected

Physiotherapy can help by:

• Teaching breathing and movement patterns that are associated with calmer physiological states
• Exploring positions and movements that feel more grounded (for example, contact with the floor, supported sitting, or slow repetitive motions)
• Encouraging body awareness without judgment, noticing sensations rather than fighting them

Interoception: Sensing What’s Happening Inside the Body

Interoception is the ability to notice internal sensations such as heartbeat, hunger, temperature, or fullness. In BPD and complex trauma, interoception can be:

• Overwhelming (too intense or scary)
• Blunted (hard to feel or recognize)
• Confusing (difficult to label or understand)

Physiotherapists can:

• Guide gentle exercises that ask, “What do you feel here?” in a curious, non-pressured way
• Help link certain sensations with functional meanings—for example, “tight chest” when anxious, “heavy limbs” when exhausted
• Support people in discovering early warning signs of stress in the body, which can then be teamed with coping tools from therapy

This can contribute to a more coherent sense of self, connecting thoughts, feelings, and physical experiences.

Trauma-Informed Physiotherapy: Safety First

For people with BPD and complex trauma, how care is delivered matters as much as what is delivered. A trauma-informed physiotherapy approach typically includes:

1. Choice and Collaboration

• The person is invited to set priorities for what feels most important: pain management, sleep, mobility, or body awareness
• The physiotherapist checks in about comfort, consent, and boundaries, especially before any touch-based techniques
• Goals and plans are negotiated together, not imposed

2. Predictability and Clear Communication

• Explaining each step of the assessment or treatment
• Saying what will happen next and checking how that feels
• Respecting no-go areas of the body, movement, or conversation

This can help reduce anxiety and minimize the risk of triggering distress.

3. Sensitivity to Triggers

People with BPD or trauma histories may feel triggered by:

• Certain positions (for example, lying down, feeling trapped, or closed spaces)
• Physical contact or proximity
• Sudden movements or unexpected sensations

A trauma-informed physiotherapist aims to:

• Offer alternative positions (such as sitting instead of lying)
• Seek continuous consent: “Is this still OK?”
• Use grounding strategies if strong emotions arise

The aim is to create a space where both body and mind are treated with respect and care.

What a Physiotherapy Journey Might Look Like

Everyone’s experience is personal, but a general pathway might involve:

Initial Assessment

A physiotherapist may explore:

• Current symptoms: pain, stiffness, fatigue, movement difficulties
• How mental health affects physical activity (and vice versa)
• Daily routines, sleep, work, and leisure activities
• Any history of injuries, operations, or health conditions

They might also ask gentle questions about what feels safe or unsafe, such as:

• Positions you prefer or avoid
• Experiences with touch or physical examinations
• Things that help you calm down if you get overwhelmed

Planning Together

Based on this, the physiotherapist and person can:

• Set realistic, flexible goals (for example, “reduce neck tension,” “sleep a bit better,” or “feel more comfortable walking outside”)
• Agree on the types of techniques that feel acceptable
• Decide on the pace of progression, including very small steps if needed

Ongoing Sessions

These might involve:

• Guided movement or stretching
• Practice of breathing or relaxation techniques
• Education about pain, posture, and body mechanics
• Reviewing how exercises fit into daily life

The process often includes adjustment and experimentation—seeing what helps, what doesn’t, and what feels manageable at different stages.

Potential Benefits and Realistic Expectations

Physiotherapy is not a miracle solution for BPD or complex mental health conditions, but it can offer several practical benefits in the right context.

Possible Positive Outcomes

People sometimes report:

• Reduced muscle tension or pain
• Slightly better sleep or energy with regular movement
• Feeling more grounded or present in their body
• Increased confidence in safe movement and activity
• A stronger sense of agency over physical symptoms
• Improved capacity to take part in psychotherapy or daily life

Important Limitations

At the same time, it is important to understand:

• Physiotherapy does not eliminate emotional pain or trauma memories
• Progress can be non-linear, with good and difficult days
• Some techniques might not feel helpful or may need modification
• Close coordination with the wider care team is often necessary, especially during periods of crisis

Seeing physiotherapy as one supportive pillar among many often leads to more balanced expectations.

Integrating Physiotherapy With Psychological and Psychiatric Care

For people with BPD or complex mental health challenges, an integrated approach can be particularly helpful.

Working Alongside Psychotherapy

Psychological therapies such as:

• Dialectical Behavior Therapy (DBT)
• Cognitive Behavioral Therapy (CBT)
• Schema therapy
• Trauma-focused therapies

address patterns of thoughts, emotions, and relationships. Physiotherapy can support this work by:

• Providing body-based tools that align with emotional regulation skills
• Helping people notice early physical signs of distress so they can apply coping strategies sooner
• Offering a space to practice embodied self-compassion, such as gentle stretching as a form of self-care

Coordinating With Psychiatric and Medical Care

People with BPD or complex mental health conditions may be receiving:

• Medication management
• Crisis or home treatment support
• Inpatient or day program services
• Support for co-existing medical conditions

Physiotherapists can:

• Share functional observations (such as changes in mobility, fatigue, or pain) with the wider team, where appropriate and with consent
• Adjust exercise plans around medication side effects (like sedation or dizziness)
• Consider how changes in mental state might call for flexible pacing of physical goals

This coordination aims to support the person as a whole, not as separate physical and mental systems.

Practical Tips: Getting the Most Out of Physiotherapy If You Have BPD or Complex Mental Health Needs

Here are some practical, non-medical pointers that people often find helpful when exploring physiotherapy.

Before You Start

• 🧠 Clarify your priorities: Are you hoping to ease pain, improve sleep, move more easily, or feel safer in your body?
• 📝 List what feels difficult: such as lying flat, being touched, being observed while moving, or discussing trauma.
• 🛡️ Think about boundaries: what you feel OK with, what you might tolerate, and what is off-limits for now.

During Sessions

• 🗣️ Speak up about discomfort – physical or emotional. It is reasonable to ask for a pause, a change of position, or a different approach.
• ⏸️ Request breaks if you feel overwhelmed. Short pauses to breathe or ground yourself can be built into the session.
• 🔄 Ask questions about why certain exercises or techniques are suggested and how they might help.

Between Sessions

• 📅 Start small and consistent: brief, gentle exercises done regularly can be easier than intense workouts.
• 🧭 Notice patterns: When does your pain or tension rise or fall? How do sleep, meals, stress, and movement affect it?
• ❤️ Frame exercises as care, not punishment: see them as actions you are taking to support yourself, rather than something you “must do perfectly.”

Quick Takeaways: When Physiotherapy May Be Worth Exploring 🤝

• You experience persistent muscle tension, pain, or fatigue alongside BPD or complex mental health struggles.
• You feel disconnected from your body and would like a gentle way to rebuild that relationship.
• You want practical, body-based strategies to complement psychological tools.
• You are curious about safe movement and exercise but feel unsure where to start because of your mental health history.
• You value a trauma-informed, collaborative approach in your healthcare.

Common Questions About Physiotherapy and BPD

“Can physiotherapy cure my BPD or trauma?”

Physiotherapy does not cure BPD or trauma. It is primarily focused on the physical and functional aspects of health—movement, pain, fatigue, and body awareness. However, by easing physical symptoms and supporting self-regulation, it can create better conditions for psychological healing and daily life functioning.

“What if I get triggered during a session?”

It is possible to feel triggered by body-based work, especially if there is a trauma history. Many physiotherapists aim to be:

• Flexible with positions and techniques
• Open to stopping, modifying, or slowing down if distress arises
• Supportive of grounding techniques such as breathing or focusing on contact with the floor or chair

Letting the therapist know about potential triggers in advance can help them adjust the approach.

“Do I have to talk about my trauma history?”

Physiotherapists typically do not need detailed trauma narratives. It can be enough to share:

• “I have a trauma history,” or
• “Some things can trigger me, such as lying flat or being touched suddenly.”

You can choose the level of detail that feels safe while still enabling the physiotherapist to be responsive to your needs.

“What if I struggle with consistency?”

Fluctuating motivation, energy, and emotional state are common in BPD and complex mental health. A physiotherapist can:

• Help design flexible plans with “good day,” “OK day,” and “hard day” options
• Emphasize small, manageable steps rather than perfection
• Reassess and adjust when life circumstances change

The aim is sustainability, not strict adherence.

Bringing the Body Back Into the Picture

BPD and complex mental health conditions are often talked about in terms of thoughts, feelings, and relationships. Yet for many people, the body quietly absorbs a great deal of the impact—through pain, exhaustion, tension, and disconnection.

Physiotherapy, particularly when delivered in a trauma-informed, collaborative way, can help:

• Ease some of the physical burden associated with long-term distress
• Support skills for self-regulation through breathing and movement
• Rebuild a more trusting, compassionate relationship with the body
• Enhance the benefits of psychological and psychiatric care

It is not a standalone solution and does not replace mental health treatment. But for some, it becomes an important part of a whole-person approach—one that recognizes that mind and body are deeply intertwined.

By acknowledging that mental health is also lived in the muscles, joints, breath, and nervous system, physiotherapy offers a way to gently reconnect with the body and, in doing so, potentially open new pathways to stability, resilience, and everyday functioning.
