# Section 1: Overview of Chronic Back Pain
## Definition and Epidemiology
Chronic back pain is defined as pain that persists for **longer than 12
weeks** (3 months) beyond the expected tissue healing time. Unlike
acute back pain, which is typically self-limiting (resolving within 4-6
weeks), chronic back pain may continue even after the initial injury or
condition has healed.
**Key epidemiological facts:**
- Back pain is the **leading cause of disability** worldwide (Global
Burden of Disease Study)
- Approximately **80% of adults** will experience back pain at some
point in their lifetime
- **20-30% of adults** have chronic back pain at any given time
- Chronic back pain is the **fifth most common reason** for primary
care visits
- Economic impact exceeds **$100 billion annually** in the United
States

## Classification of Back Pain
,3|Page
| Type | Duration | Characteristics |
|------|----------|-----------------|
| **Acute** | <4 weeks | Usually self-limiting; often mechanical or
traumatic |
| **Subacute** | 4-12 weeks | Transitional phase; may require
intervention |
| **Chronic** | >12 weeks | May be persistent or episodic; often requires
multidisciplinary approach |
| **Recurrent** | Episodic | Multiple episodes of acute pain over time |

## Chronic vs. Acute Back Pain: Key Differences
| Feature | Acute Back Pain | Chronic Back Pain |
|---------|-----------------|-------------------|
| Duration | <12 weeks | >12 weeks |
| Cause | Usually identifiable (mechanical, traumatic) | Often
multifactorial; may have no clear cause |
| Healing | Expected within expected timeframe | Healing may be
incomplete or absent |
| Psychological factors | Minimal | Significant (depression, anxiety,
catastrophizing) |
, 4|Page
| Disability | Usually minimal | Often significant |
| Treatment focus | Symptom relief, healing | Function, coping, quality of
life |
| Opioid use | Short-term if needed | Chronic use problematic; often
discouraged |

# Section 2: Pathophysiology of Chronic Back Pain
## The Transition from Acute to Chronic Pain
The transition from acute to chronic back pain involves complex
interactions between biological, psychological, and social factors.
**Key mechanisms:**
1. **Central sensitization** – Amplification of pain signals within the
central nervous system
2. **Peripheral sensitization** – Lowered threshold for nociceptor
activation
3. **Neuroplastic changes** – Altered pain processing in the brain and
spinal cord
