Understanding Regional Interdependence in Physiotherapy: A Detailed Examination
Introduction to Regional Interdependence in Physiotherapy
As physiotherapy continues to evolve, the concept of Regional Interdependence (RI) has become increasingly vital for understanding musculoskeletal dysfunctions. This model suggests that dysfunction in one body region can influence seemingly unrelated areas. For practitioners, understanding this concept is essential for providing comprehensive care and achieving optimal patient outcomes.
Our physiotherapy courses delve deep into the Regional Interdependence model, equipping clinicians with the knowledge and skills to apply this approach effectively in practice. By the end of this article, you’ll understand RI’s importance, mechanisms, and its profound clinical implications for physiotherapists.
What is Regional Interdependence?
At its core, Regional Interdependence (RI) posits that musculoskeletal dysfunctions in one area can lead to compensatory changes or symptoms in other parts of the body. Traditionally, treatment focused primarily on the affected area—whether it's the knee, shoulder, or spine—without considering other regions that may be contributing to the dysfunction. The RI model challenges this view, encouraging practitioners to consider the broader body as an interconnected system.
For example, a patient with chronic low back pain may also exhibit impairments in the hips or thoracic spine, which may be influencing the pain. In this case, focusing only on the lumbar region could result in a partial or ineffective treatment. RI opens the door to more holistic and targeted interventions that address the root of musculoskeletal issues.
RI vs. Localized Treatment Approaches
Most traditional treatments view musculoskeletal problems in isolation, focusing only on the symptomatic region. However, RI emphasizes the importance of considering the entire kinetic chain—the idea that movement in one joint or region affects others. This concept has been instrumental in shaping more modern and effective physiotherapy practices.
The Evolution of the Regional Interdependence Model
While Regional Interdependence has recently gained traction, the idea of interconnected body regions is not new. As early as the mid-20th century, clinicians observed that pain could arise from seemingly unrelated regions. Inman and Saunders (1944) suggested that distant pain sources could reflect a deeper, more complex issue. Later, Slocum (1950s) expanded on this, noting that an injury in one area, such as a foot injury, could lead to altered mechanics and dysfunction in other regions, like the shoulder.
The term Regional Interdependence was formalized by Wainner et al. (2007), who proposed that clinicians consider the body as a unified system when diagnosing and treating patients. By treating areas distant from the primary complaint, therapists can significantly improve outcomes.

Mechanisms of Regional Interdependence in Physiotherapy
The mechanisms behind Regional Interdependence (RI) involve a variety of complex processes, including biomechanical, neurophysiological, and systemic responses.
1. The Biomechanical Kinetic Chain
The kinetic chain is one of the core principles behind RI, which explains how a deficit in one joint or region can affect others. For instance, decreased ankle dorsiflexion can lead to compensatory movements in the knee, hip, and even the spine. This compensation may eventually cause pain or dysfunction in these areas. In practice, treating the root cause—in this case, the ankle—can relieve symptoms in other regions.
2. Neurophysiological Influences
Another critical mechanism is neurophysiological connectivity. Research shows that interventions such as manual therapy can influence distant regions through neural pathways. For example, spinal manipulation in one area can affect motor neuron excitability and muscle activation in regions far from the manipulated joint (Suter et al., 2011). These findings underline the importance of understanding RI in physiotherapy treatments.
3. Allostatic Load and Systemic Responses
The allostatic process, or the body’s response to stress and imbalance, also plays a key role in RI. When one part of the body is injured or stressed, other systems adapt to maintain balance, sometimes resulting in dysfunction elsewhere. This interconnected response emphasizes why physiotherapists must take a holistic view of the body when developing treatment plans.
Clinical Implications for Physiotherapists
Understanding Regional Interdependence transforms how physiotherapists approach assessment and treatment. Rather than focusing solely on the area of pain, clinicians can look for compensatory changes in other regions that may be contributing to the dysfunction. For example:
- Low back pain may be influenced by impairments in the hip or knee (Stupar et al., 2010).
- Shoulder pain may be affected by thoracic spine dysfunction (Mintken et al., 2010).
By adopting an RI approach, physiotherapists can improve patient outcomes through comprehensive, integrated treatment plans. This model also encourages therapists to consider non-musculoskeletal factors like psychological stressors, which can exacerbate musculoskeletal symptoms.

Supporting Research on Regional Interdependence
A wealth of research supports the efficacy of the Regional Interdependence model. For example:
- Cleland et al. (2005) demonstrated that thoracic spine manipulation improved neck pain and range of motion, supporting the idea of treating adjacent regions for better outcomes.
- Souza and Powers (2009) found that improving hip mechanics reduced knee pain, reinforcing the importance of the kinetic chain in treating lower-limb dysfunctions.
These findings highlight the importance of expanding assessments beyond localized symptoms. By applying the RI model, physiotherapists can uncover hidden dysfunctions and develop more effective treatment strategies.
How to Apply the Regional Interdependence Model in Your Practice
Implementing Regional Interdependence in your practice requires a shift in both assessment and treatment strategies. When evaluating a patient:
- Expand Your Assessment: Assess the entire kinetic chain, not just the area of pain.
- Consider Neurophysiological Responses: Recognize how manual therapies in one region can affect other areas through neural pathways.
- Factor in Psychological Influences: Address biopsychosocial factors, such as stress and fear-avoidance, that could impact recovery.
By adopting these steps, physiotherapists can offer more holistic and effective treatments, ultimately improving patient satisfaction and long-term outcomes.
