Summary
Movement-evoked pain (MEP) in adults is characterized by distinct biopsychosocial domains. Physical activity levels were inversely associated with MEP, highlighting key relationships for understanding and treating this condition.
Area of Science:
- Pain research
- Biopsychosocial health
- Chronic pain management
Background:
- Movement-evoked pain (MEP) affects many US adults with chronic pain.
- MEP is influenced by biopsychosocial factors and distinct mechanisms.
- Limited understanding of MEP characteristics and mechanisms hinders diagnosis and treatment.
Purpose of the Study:
- To identify descriptive domains characterizing MEP.
- To explore relationships between biopsychosocial factors across MEP domains.
Main Methods:
- Secondary analysis of 178 individuals (45-85 years) with knee pain.
- Defined 6 characteristic domains from 46 MEP-related variables.
- Used functional activity pain ratings as primary MEP variables.
- Employed Pearson correlations and weighted correlation network analysis.
Main Results:
- Identified unique pain characteristics associated with MEP.
- Physical activity duration inversely correlated with variables in 4 of 6 domains.
- Weighted correlation network analysis supported domain classification.
- Strongest interdomain relationships found between MEP, Mechanical Pain, and Multiple Pain Characteristics and Symptoms.
Conclusions:
- Bolstered fundamental understanding of MEP.
- Identified relevant mechanistic domains for MEP.
- Elucidated key biopsychosocial and interdomain relationships in MEP.

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

01:25Analgesia and Pain Management
614
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

01:29Blood and Nerve Supply to the Bones
11.0K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
