## Pain Physiology & Psychology: A Biopsychosocial Approach
- Overview of patient communication, coping strategies, and regulatory focus in physiotherapy practice.

## The 4 Stages of Pain Physiology
- **Transduction:** Nociceptors convert damage into electrical signals.
- **Transmission:** Signals travel via A-delta and C-fibers.
- **Modulation:** Descending pathways inhibit/facilitate signals (Gate Control Theory).
- **Perception:** Subjective brain integration.

## The Gate Control Theory
- Proposed by Melzack & Wall (1965).
- Non-painful input (A-beta fibers) can 'close the gate' in the dorsal horn, reducing pain.

## Chronic Pain & Central Sensitization
- Explains Hyperalgesia and Allodynia where the CNS remains hypersensitive ('alarm stuck on').
- Descending modulation involves the PAG and RVM structures using Serotonin and Endogenous Opioids.

## Psychology of Pain
- **Biopsychosocial Model:** Integrates biological, psychological (beliefs, catastrophizing), and social (context, environment) factors.
- **Fear-Avoidance Model:** How fear leads to physical deconditioning and depression.
- **Pain Catastrophizing:** Defined by rumination, magnification, and helplessness.

## Communication & Coping Strategies
- **OARS Model:** Open questions, Affirmations, Reflections, and Summaries.
- **Adaptive Coping:** Task-persistence, seeking support, and relaxation.
- **Passive Coping:** Reliance on medication, avoidance, and resting.

## Regulatory Focus Theory
- **Promotion Focus:** Emphasis on gains and achievement (e.g., "getting back to sport").
- **Prevention Focus:** Emphasis on safety and non-loss (e.g., "avoiding flare-ups").

## Clinical Application
- Early screening for 'yellow flags'.
- Using 'Hurt ≠ Harm' education.
- Graded exposure for feared movements.
