The Future of Empathy: Technology Aims to Objectively Measure Pain
For centuries, assessing pain has relied on subjective reports – a patient’s answer to the question, “On a scale of one to ten, how much pain are you in?” But this simple method is fraught with inconsistency. How can a physician truly know if one person’s ‘five’ aligns with another’s experience? Now, a groundbreaking platform developed through a collaboration between NTT Docomo and PaMeLa (Pain Measurement Laboratory) is attempting to move beyond subjective assessment, offering a potential pathway to objectively quantify and even share the sensation of pain.
This innovation isn’t merely about refining pain scales; it’s about deepening human understanding. NTT Docomo’s “Feel Tech” project, initially focused on transmitting sensations like touch and taste, now tackles the uniquely challenging realm of pain. The technology was showcased last month at the Combined Exhibition of Advanced Technologies (CEATEC) in Japan, signaling a significant step toward a future where empathy can be technologically augmented.
How Does Pain-Sharing Technology Work?
The system employs a three-pronged approach. First, electroencephalography (EEG) is used to map brainwave activity, which is then processed by an artificial intelligence model to generate a pain score ranging from 0 to 100. This score represents the sender’s perceived pain intensity. Crucially, the system doesn’t simply transmit the sensation; it aims to calibrate it. A heat-based actuation device is used to deliver a stimulus to the receiver, adjusted based on their individual sensitivity, ensuring the experience feels equivalent to the sender’s.
Currently, the platform focuses on thermally induced pain – a controlled and safe method for research and development. PaMeLa’s prior research utilized thermal stimulation, analyzing data from 461 participants with machine learning algorithms to refine pain intensity grading. However, the long-term vision extends far beyond heat. Docomo anticipates the ability to convey a wider spectrum of physical and even psychological pain, opening up possibilities for applications in fields ranging from medical training to therapeutic interventions.

The Challenges of Quantifying Subjective Experience
While the technology holds immense promise, experts caution that it’s still in its nascent stages. Dr. Carl Saab, founder and director of the Cleveland Clinic Consortium for Pain, highlights the complexities inherent in measuring such a subjective phenomenon. “What is the use case?” he asks, pointing to the need for a clear application before widespread adoption. He also emphasizes the critical distinction between pain experienced by healthy volunteers and that of individuals suffering from chronic conditions.
Dr. Saab explains that the brain activity associated with temporary, experimentally induced pain differs significantly from the complex neurological patterns observed in patients with chronic pain, migraine, or other persistent conditions. Chronic pain is often intertwined with anxiety, depression, and the side effects of medication, adding layers of complexity that a simple EEG reading may not fully capture. His research, which involved submerging participants’ arms in ice water, demonstrated that pain patients exhibited far more intricate brain activity than healthy volunteers.
The future of this technology hinges on rigorous validation in clinical settings. Docomo plans to collaborate with hospitals to assess its efficacy and refine its algorithms. PaMeLa recently completed a clinical trial analyzing EEG signals before and after painkiller administration during surgeries, further demonstrating their commitment to real-world application. But as Dr. Saab aptly points out, “Pain is a multidimensional experience. When you say you’re measuring someone’s pain, you always have to be careful about what kind of dimension you are measuring.”
Could this technology revolutionize our understanding of empathy and pain management? Or will the inherent subjectivity of pain prove too formidable a challenge? What ethical considerations should guide the development and deployment of pain-sharing technology?
Further research is being conducted to explore the potential of this technology in various conditions, including exercise-induced pain, acute pain from injections, and the complexities of chronic pain. The ultimate goal is to create a more nuanced and objective understanding of pain, paving the way for more effective treatments and a more compassionate approach to patient care.
Frequently Asked Questions About Objective Pain Measurement
What is the primary goal of the pain-sharing technology developed by NTT Docomo and PaMeLa?
The primary goal is to objectively measure and share individual perceptions of pain, moving beyond the limitations of subjective self-reporting.
How does the technology utilize electroencephalography (EEG) in pain assessment?
EEG is used to measure brainwave activity, which is then analyzed by an AI model to generate a pain score representing the sender’s perceived intensity.
What are the current limitations of this pain measurement technology?
The technology is still in its early stages and faces challenges in accurately representing the complexities of chronic pain, which is often linked to psychological factors and medication side effects.
What is the “Feel Tech” project, and how does this pain-sharing technology fit into it?
“Feel Tech” is NTT Docomo’s broader initiative to develop a human-augmentation platform for deepening mutual understanding, with pain being the latest sense targeted for transmission.
Is the pain-sharing technology currently available for clinical use?
No, the technology is still under development and undergoing clinical trials to validate its efficacy and safety before it can be used in medical settings.
What types of pain can this technology currently measure and share?
Currently, the platform focuses on thermally induced pain, but the long-term goal is to convey a wider range of physical and psychological pain sensations.
