Pain01:20

Pain

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...
Nociception01:44

Nociception

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. Thus, pain helps the...
Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

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...

Area of Science:

  • Neuroscience
  • Pain Management
  • Psychology

Background:

  • Chronic back pain is a prevalent condition with limited understanding of visual feedback's impact.
  • Previous research has not explored the effect of visualizing one's own back on pain perception.

Purpose of the Study:

  • To investigate the influence of online video feedback of the back on pain perception in individuals with and without chronic back pain.
  • To assess whether visualizing the back affects pain threshold and pain tolerance.

Main Methods:

  • 18 patients with chronic back pain and 18 healthy controls participated.
  • Online video feedback of the back and hand was provided during painful pressure and electrical stimuli.
  • Pain intensity and unpleasantness were rated using an 11-point numerical rating scale.

Main Results:

  • Visual feedback of the back significantly reduced perceived pain intensity compared to feedback of the hand.
  • This pain reduction effect was observed in both chronic back pain patients and healthy controls.
  • No significant difference was found in pain threshold or tolerance between feedback conditions.

Conclusions:

  • Visualizing one's own back can be a viable strategy for modulating pain perception.
  • Findings suggest potential for novel interventions, such as augmented reality applications, for managing chronic back pain.
