Beyond Fight or Flight: Exploring Tonic Immobility's Role in Trauma

When confronted with danger or distressing experiences, most people are familiar with the 'fight or flight' response as a means of survival. However, there is a lesser-known but equally crucial mechanism known as 'tonic immobility' that plays a vital role in the way we react to trauma. Tonic immobility is a state of temporary paralysis or freezing, during which an individual is unable to move or react to their environment.


At Staying Sane 101, our team of dedicated counsellors recognises the importance of understanding and addressing the complexities of tonic immobility and its impact on the emotional well-being of those who have experienced trauma. In this article, we will explore the biological foundations of tonic immobility, its manifestations within trauma response, and the significance of acknowledging its role in the process of healing from traumatic events.


Understanding the Biological Basis of Tonic Immobility


Tonic immobility is a primitive and evolutionary hard-wired defence mechanism designed to protect individuals from harm in the face of life-threatening situations where fight or flight is not possible or would prove counterproductive. In the animal kingdom, tonic immobility is often observed in prey animals when captured by predators, functioning as a last resort strategy to increase the chance of survival. This 'freeze response' serves to conserve energy and decrease the likelihood of further harm, as predators tend to be less interested in prey that appears lifeless or unresponsive.


In humans, the freeze response is mediated by a complex interplay of biochemical and neural pathways involving the amygdala, hypothalamus, and periaqueductal grey – the critical brain structures responsible for processing and responding to threats. When the brain perceives a threat it cannot escape or overcome, it may trigger tonic immobility as a self-protective response.


Manifestations of Tonic Immobility in the Context of Trauma


In the context of human trauma, tonic immobility can manifest in various ways, depending on the specific circumstances and individual factors at play. Some common manifestations of the freeze response during or following traumatic events may include the following:


1. Physical Immobility: The individual may become physically immobilised, experiencing numbness, stiffness, or an inability to move or react to their environment. This may be accompanied by sensations of weakness or heaviness in the limbs.


2. Emotional Numbing: Alongside physical immobility, individuals may also experience emotional numbing, characterised by a temporary detachment from their emotions or a 'spacing out' sensation.


3. Diminished Pain Perception: Tonic immobility may result in a decreased perception of pain during the traumatic event, acting as a protective mechanism to shield the individual from further distress.


4. Altered Time Perception: Some individuals may experience a sense of time slowing down or becoming distorted during the freezing response, impacting their ability to accurately recount the sequence of events surrounding the trauma.


Implications of Tonic Immobility for Trauma Recovery


The occurrence of tonic immobility during traumatic events can hold significant implications for individuals navigating the process of healing and recovery. Some of these implications may include:


1. Shame and Guilt: Despite being an involuntary and innate survival response, some individuals may experience intense feelings of guilt or shame associated with their tonic immobility response, misinterpreting it as a sign of weakness or failure to resist or escape the threat.


2. Memory Fragmentation: As tonic immobility can disrupt the normal cognitive processing of events and impact the perception of time, individuals may struggle with incomplete, fragmented, or disjointed memories of the trauma, which can pose challenges for therapeutic interventions.


3. Chronic Freeze Response: In some cases, the freeze response can become ingrained in an individual's neural pathways, causing them to revert to tonic immobility during stressful situations or when faced with triggers reminiscent of the original trauma, further prolonging distress and complicating recovery.


Incorporating Tonic Immobility into Trauma-Informed Therapy


Given the profound impact of tonic immobility on individuals' experiences of trauma and their subsequent attempts at healing, it is essential for therapeutic interventions to acknowledge and accommodate its role. By integrating an understanding of tonic immobility into trauma-informed therapy, counsellors can better support their clients in navigating the complex web of emotions and symptoms arising from the freeze response. Some strategies for incorporating tonic immobility into trauma therapy may include:


1. Psychoeducation: Educating clients about the nature, purpose, and manifestations of tonic immobility can help to normalise and validate their experiences, facilitating a sense of empowerment and self-compassion.


2. Processing Feelings of Shame and Guilt: Therapists can work with clients to identify and challenge feelings of guilt or shame surrounding tonic immobility, supporting them as they recognise that their response is an involuntary and innate survival mechanism.


3. Addressing Memory Fragmentation: Specialists can utilise techniques such as Eye Movement Desensitisation and Reprocessing (EMDR) or Narrative Therapy to help clients process and integrate fragmented memories of traumatic events, fostering a sense of coherence and understanding.


4. Somatic Interventions: Introducing somatic therapies, like Sensorimotor Psychotherapy or Somatic Experiencing, can help individuals reconnect with their bodies, develop greater awareness of physical sensations, and learn to regulate their freeze response during stressful situations.


Unlocking the Path to Recovery Through Understanding Tonic Immobility


The phenomenon of tonic immobility holds significant implications for understanding and recovering from traumatic experiences. By exploring the biological basis, manifestations, and essential role of this lesser-known freeze response, individuals and their therapists can develop a comprehensive approach to healing that acknowledges and integrates its impact on trauma recovery.
