Mid-Air Tactile Stimulation for Pain Distraction
IEEE Transactions on Haptics
|June 19, 2018
Summary
Virtual Reality (VR) with tactile stimulation significantly increases pain tolerance time during the cold pressor test. This effect is more pronounced in individuals with higher pain tolerance, suggesting VR haptics enhance pain distraction.
Area of Science:
- Pain management and perception
- Human-computer interaction
- Virtual Reality (VR) and haptics
Background:
- Pain control has historically relied on sensory distraction.
- Virtual Reality (VR) and haptic technologies offer novel methods for pain distraction.
- Mid-air ultrasound tactile stimulation presents a new modality for sensory feedback.
Purpose of the Study:
- To investigate the efficacy of VR and mid-air ultrasound tactile stimulation in reducing perceived pain.
- To compare pain distraction effects between VR with and without tactile feedback.
- To assess the influence of pain tolerance on the effectiveness of VR-based pain distraction.
Main Methods:
- An experimental study involving 50 participants using the cold pressor test (hand immersion in 2°C water).
- Three conditions: control (no distraction), VR game without tactile feedback, and VR game with tactile feedback.
- Evaluation of pain tolerance time, perceived pain ratings, and quality of experience.
Main Results:
- VR with tactile stimulation significantly increased pain tolerance time compared to VR alone and the control condition.
- Tactile stimulation was more effective for pain distraction in high pain tolerance participants.
- No significant differences in perceived pain or quality of experience were found between VR and VR with tactile feedback conditions.
Conclusions:
- VR combined with tactile stimulation enhances pain tolerance by increasing distraction.
- The effectiveness of VR haptics for pain management is modulated by individual pain tolerance levels.
- VR and tactile feedback may induce positive emotional states, contributing to pain distraction.

810
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

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...

01:27Air-entraining Agents
276
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

01:28Effects of Air-entrainment in Concrete
394
Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...

Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.

1.7K
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...
