Immersive VR-Biofeedback Shows Promise for Fibromyalgia Care
Immersive virtual reality combined with multisensor biofeedback (IVR-BF) demonstrated significant potential for alleviating chronic pain and improving quality of life in patients with fibromyalgia after five treatment sessions. METHODOLOGY: Researchers conducted a pilot randomized controlled trial at a tertiary academic referral center for fibromyalgia to assess the feasibility and efficacy of IVR-BF in reducing chronic pain and improving quality of life in patients with fibromyalgia. They included 23 women (median age, 47 years) with chronic nononcologic widespread musculoskeletal pain who met the criteria for fibromyalgia. Participants were randomly assigned to either the immediate treatment group that completed five IVR-BF sessions within 10 days (n = 12) or the waitlist control group that did not receive any treatment during the period (n = 11). The waitlist group received treatment after completion of sessions in the treatment group. Both groups were monitored for up to 15 days after the final session. During each 15-minute virtual reality session, participants sat comfortably in an armchair and wore a headset. A Quest Touch controller was provided for a brief interaction with the virtual environment, with two tasks of 3 minutes each assigned during the session. Heart rate, skin conductance, and respiratory activity were recorded using electrodes and sensors. Participants completed questionnaires such as the visual analog scale for pain (VAS pain) and the Fibromyalgia Impact Questionnaire (FIQ) for the impact of the condition on daily life; the primary outcome was reduction (at least 30%) in pain intensity, assessed through VAS scores. TAKEAWAY: Patients receiving IVR-BF experienced significantly greater pain reduction than untreated control patients, with a 50.97% improvement in VAS pain scores. Patients receiving IVR-BF showed a significant improvement in VAS pain from baseline after five sessions ( P < .001), whereas the untreated control patients did not show this improvement. < .001), whereas the untreated control patients did not show this improvement. Likewise, patients receiving IVR-BF experienced significantly greater reductions in FIQ scores than untreated control patients, with a 39.73% improvement in scores. Improvements were also noted in respiratory rate, heart rate variability, and skin conductance levels across sessions. Overall, 78.25% of patients experienced no adverse events, and one patient had moderate blurred vision during and immediately after IVR-BF sessions, leading to discontinuation. Additionally, 71.43% reported being satisfied with the intervention. IN PRACTICE: 'The study demonstrates the feasibility and the promising potential of the IVR-BF approach for FM [fibromyalgia] treatment and suggests that IVR can enhance biofeedback efficacy by fostering a more engaging and relaxing experience,' the study authors wrote. SOURCE: This study was led by Luca Chittaro, MSc, University of Udine, Udine, Italy. It was published online on May 15, 2025, in ACR Open Rheumatology . LIMITATIONS: This trial lacked a placebo control group and may be potentially subjected to investigator bias due to unmasked results. The duration of the study was short, and its small sample size comprising women may limit the generalizability of the findings. DISCLOSURES: The study did not report any specific funding. The authors declared having no conflicts of interest. This article was created using several editorial tools, including AI, as part of the process.

2,500-year-old shipwreck and anchors discovered off coast of Sicily
Ammon News - A shipwreck dating back to the 5th and 6th centuries B.C. was discovered near Sicily along with ancient anchors made from stone and iron, Italian officials said. The 2,500-year-old wreck was found buried beneath sand and rocks by crews working on an underwater excavation project in the waters of Santa Maria del Focallo, near Ispica at the southern tip of the Italian island, said Sicily's Superintendent of the Sea in a statement Monday. When archaeologists unearthed the sunken ship, they discovered a hull built using an "on-the-shell" construction technique, a simplistic early shipbuilding method often traced to populations around the Mediterranean. They also found a trove of anchors several feet from the wreckage, the superintendent said, two of the anchors were made from iron and likely originated in the 7th century A.D. The other four anchors, which were made from heavy stone, probably date back to the prehistoric era. Archaeologists created a three-dimensional model of the shipwreck and collected samples from the artifacts for analysis, hoping to understand more about the materials that compose them. "This discovery represents an extraordinary contribution to the knowledge of the maritime history of Sicily and the Mediterranean and highlights once again the central role of the Island in the traffic and cultural exchanges of antiquity," said Francesco Paolo Scarpinato, Sicily's regional councilor for cultural heritage and Sicilian identity, in a translated statement on the shipwreck published by the University of Udine. "The wreck, dating back to a crucial period for the transition between archaic and classical Greece, is a precious piece of the submerged Sicilian cultural heritage." The three-week excavation in Santa Maria del Focallo, which was part of the Kaukana Project, an archaeological research initiative, ended in September, but officials did not share their findings until this week. The superintendent of the sea led the initiative with archaeologists from the University of Udine, near the site of the excavation. Those involved with the project say this wreck could potentially shine a light on an important chapter of ancient Greece, which occupied Sicily for hundreds of years until the island was taken by Rome around 200 B.C. Massimo Capulli, a coordinator of the Kaukana Project and professor at the University of Udine, added in a separate statement released by the university that studying the wreck may help illuminate how trade happened between ancient Greeks and Carthaginians, two groups that thousands of years ago fought for control of the seas around present-day Sicily. "We are in fact faced with material evidence of the traffic and trade of a very ancient era," Capulli said. CBS
