Study Notes

Pain Types and Viscerogenic Pain Patterns

Pain is an unpleasant sensory and emotional experience, a primary symptom in physical therapy.
Pain is recognized as the "fifth vital sign," alongside blood pressure, temperature, pulse, and respiration.
Pain patterns characteristic of systemic disease are crucial in screening.

Mechanisms of Referred Visceral Pain

Visceral pain originates from internal organs, described as dull.
Mechanisms include:
- Embryologic development
- Multisegmental innervation
- Direct pressure and shared pathways

Mechanisms of Referred Visceral Pain- Embryologic Development

Diagrams showing referral patterns for various organs and conditions. (e.g., Liver pain can be felt in the shoulder, gallbladder pain in the shoulder, etc.)

Mechanisms of Referred Visceral Pain- Multisegmental Innervation

Diagram illustrating neural pathways connecting organs to different spinal segments. (e.g., Different areas of the abdomen or chest are connected to different nerves in the spinal cord.)

Mechanisms of Referred Visceral Pain- Direct Pressure and Shared Pathways

Diagrams demonstrating anatomical structures and pathways that can lead to referred pain. (e.g., organs touching each other, sharing neural pathways, or direct nerve compression from organs.)

Assessment of Pain and Symptoms

Pain measurement involves assigning numerical values to pain intensity.
Pain assessment includes detailed health history, physical examination, medication history, functional status assessment, and psychosocial-spiritual factors.
Refer to other reading material (Fig. 3.6) for more specific details.

Characteristics of Pain

Essential characteristics for assessment:
- Location
- Description (e.g., knife-like, dull, boring, burning, throbbing, prickly, deep aching, sharp)
- Intensity
- Duration
- Frequency
- Aggravating and relieving factors

Location of Pain

Precise description of the pain location is crucial.
Questions to ask the client:
- Show me exactly where your pain is located.
- Do you have any other symptoms elsewhere?
- If yes, what causes the symptoms in that other area?
Localized pain suggests a localized cause (e.g., injury), non-localized suggests systemic potential.

Description of Pain

Specific descriptors help differentiate pain types. (e.g., knife-like, boring, colicky, dull, burning, throbbing, sharp, deep aching).
Differentiate "aching" pain from pain in muscles by applying pressure and observing response.
Special pain characteristics (e.g., waves, deep aching) may suggest systemic conditions.

Intensity of Pain

Use pain rating scales to quantify pain severity.

Frequency and Duration of Pain

Asking about pain duration helps determine if it's a short-term or chronic condition.
Questions about constant vs. intermittent pain, noticing pain immediately upon awakening, etc.

Pattern of Pain

Table of pain patterns and associated characteristics (e.g., throbbing, pounding, radiating, worsening).
Common referred pain areas (chest, back, shoulders, hips).
Systemic diseases often produce characteristic pain patterns.

Sources of Pain

Categories include:
- Cutaneous: superficial pain from skin and subcutaneous tissue.
- Somatic: pain from musculoskeletal structures.
- Visceral: pain from internal organs.
- Neuropathic: pain from nerve damage or dysfunction.
- Referred: pain felt in areas distant from the source.

Comparison of Systemic Versus Musculoskeletal Pain Patterns

Refer to reading material, Fig 3.2, for details.

Characteristics of Viscerogenic Pain

Pain characteristics often involve gradual, progressive, and cyclical pain patterns, constant pain, and failure of typical physical therapy strategies to address.

Guidelines for Immediate Physician Referral

When to refer immediately:
- Patients with risk factors and signs of rhabdomyolysis.
- Patients with bone pain relief disproportionately from aspirin.
- Joint pain with unknown origins and recent infections.

Guidelines for Referral (Required)

When to refer:
- Proximal muscle weakness with reflexes changes and past cancer history
- Joint pain with no known cause plus skin rash, infection (UTI, respiratory)
- Diffuse pain potentially signaling neurological or visceral issues.
- Signs of anxiety, depression and panic disorder.
- New onset of back, neck, TMJ, shoulder or arm pain brought on by exercise or exertion.
- Persistent pain during weight bearing or bone, especially in older adults with risks (osteoporosis, falls) or cancer history.

Description

This quiz explores the types of pain, particularly viscerogenic pain, and its significance in physical therapy. It covers the mechanisms of referred visceral pain, embryologic development, and multisegmental innervation, illustrating how pain from internal organs can present in different body areas. Understanding these patterns is essential for effective diagnosis and treatment.
