A study of 28 shoulder replacement patients found that their driving skills improved significantly at 12 weeks post-surgery, with a decrease in simulator collisions. Patients who drove less than 1,800 miles per year incurred more collisions, suggesting that long-distance driving may be safe earlier
Researchers found that younger female patients, particularly those with post-traumatic or rheumatoid arthritis, had the highest pain scores. Surgical factors like general anesthesia and longer tourniquet time during knee replacement also contribute to postoperative pain.
A double-blind, placebo-controlled trial found no decrease in knee cartilage damage or improvement in bone marrow lesions with glucosamine supplementation. Glucosamine did not reduce urinary excretion of C-telopeptides of type II collagen, a predictor of cartilage destruction.
Researchers at Chalmers University of Technology developed a new treatment method for phantom limb pain, using muscle signals from the amputated arm stump to drive an augmented reality system. The patient experienced drastically reduced pain and was no longer awakened by intense periods of pain at night.
A new study investigates whether a hangover can delay or hasten subsequent drinking, finding minimal effect on the timing of drinks. Researchers suggest alternative hypotheses linking hangovers and alcoholism, such as increased risk factors for losing control over drinking.
A University of Virginia study reveals that racial bias in pain perception emerges during middle childhood, strengthening by age 10. Parents and teachers should address these biases early, before they develop into adulthood.
A study published in Social Cognitive and Affective Neuroscience found that social exclusion activates the same brain circuits responsible for physical pain. The research used real people in videos to simulate social exclusion and physical pain, revealing activation of the posterior insular cortex in both conditions.
Researchers have developed a new method to treat phantom limb pain, using muscle signals from the arm stump to drive an augmented reality system. The patient's pain was drastically reduced, and he now experiences periods of complete relief.
A neurotensin conjugate has shown effective transportation across the blood brain barrier and dose-dependent pain relief in animal models. In contrast, hematopoietic stem cell transplantation has been found to impact T cell repertoire in multiple sclerosis patients, with diverse repertoires associated with better treatment responses.
Researchers found that non-restorative sleep is a strong predictor of widespread pain onset among adults over 50. Anxiety and poor physical health also increase the risk of developing widespread pain. The study suggests combined interventions for both site-specific and widespread pain are needed for older adults.
Research published in Acupuncture in Medicine found that widely used acupuncture needles have significant surface irregularities and inconsistencies, which could lead to painful reactions, bleeding, or bruising. The study calls for manufacturers to review and improve their quality control procedures for needle fabrication.
Researchers discovered that bacterial LPS components directly activate pain sensors, triggering immediate pain and inflammatory responses. This finding reveals a new target for drugs designed to treat bacterial infections, such as pneumonia and meningitis.
