SILVER-Pain Dataset

This open-access record contains the lower-risk component of the dataset: four-channel physiological signals and associated self-reported pain labels. Physiological signals in the younger cohort were collected using the Empatica E4 wristband. Physiological signals in the older cohort were collected using the Empatica EmbracePlus wristband, a newer device in the Empatica wearable line.

The broader SILVER-Pain dataset also includes additional modalities collected during the study, including thermal video, depth video, RGB-derived facial action units (FAUs), and selected screening-questionnaire variables. Because those files may present a non-negligible risk of participant re-identification or sensitive information disclosure, they are not included in this open-access Mendeley record. Instead, they are available separately under a controlled-access process requiring user registration, verifiable identity information, and a signed Data Usage Agreement (DUA), consistent with the controlled-access model described by Scientific Data.

The controlled-access materials and request instructions are described here: https://websites.umass.edu/xiandu/data-sharing/silver-pain-restricted/.

This record includes both original physiological files and processed, ML-ready derivatives for the open-access component. Baseline utilities for parsing, synchronization, and preprocessing are available at https://github.com/straybird16/SILVER-pain. RGB-derived FAUs in the controlled-access component were obtained from RGB video using the open-source ME-GraphAU library: https://github.com/CVI-SZU/ME-GraphAU.

**Access Note**

This Mendeley record contains ONLY the open-access portion of the SILVER-Pain dataset. Additional controlled-access files, including thermal video, depth video, RGB-derived FAUs, and screening-questionnaire variables, are available separately through a request process requiring signed agreement to the DUA: https://websites.umass.edu/xiandu/silver-dua.
