Postherpetic neuralgia

This study tests whether the oral medication venlafaxine, typically used for depression, can prevent postherpetic neuralgia—a persistent nerve pain that often follows a shingles rash. Researchers will enroll 832 adults who have had a shingles rash for less than 30 days and are ex…

This study tests a device called Walkasins, worn on the lower legs, that vibrates to give sensory feedback about foot pressure. The goal is to see if using it daily for six months improves balance and walking in 200 adults aged 55+ with peripheral neuropathy. Participants will do…

This study looks at whether electroacupuncture (a type of acupuncture with mild electric pulses) can help relieve pain from shingles and reduce the chance of long-term nerve pain. About 228 adults with shingles will be split into three groups: one gets electroacupuncture plus sta…

This study tests whether a new tablet called Y-4, which combines two drugs (pregabalin and riluzole), can better relieve postherpetic neuralgia—persistent nerve pain after shingles—compared to pregabalin alone. About 160 adults in China will take either Y-4 or pregabalin for 14 w…

This study tests a new type of deep brain stimulation called 'Burst-DBS' for people with long-term facial pain or pain after a stroke. Twenty adults will have electrodes placed in the thalamus (a pain-related brain area) and try both standard and burst stimulation patterns. The g…

This study tests three different injections—exosomes, platelet-rich plasma (PRP), and steroids—to see which best eases long-term nerve pain after shingles. 45 adults with pain lasting at least 3 months will get four treatments every two weeks. Researchers will measure pain, quali…

This study tests a non-invasive device that gently stimulates a nerve in the ear to see if it can reduce pain and improve daily life for people with post-herpetic neuralgia (long-term nerve pain after shingles). About 34 adults aged 35-65 with persistent pain will receive the sti…

This study compares two treatments for long-lasting nerve pain after shingles (postherpetic neuralgia). Researchers will give 50 adults either a nerve block or a radiofrequency treatment and measure pain levels. The goal is to find which option works better for easing this stubbo…

This study tests whether a noninvasive procedure called transcutaneous pulsed radiofrequency can reduce chronic pain from postherpetic neuralgia, a complication of shingles. The procedure delivers electrical pulses through electrodes placed on the skin over the painful area. Rese…

This study tests whether an ultrasound-guided nerve block with steroids can reduce pain in people with post-herpetic neuralgia—persistent nerve pain after shingles—that hasn't improved with standard treatments. Sixty adults aged 20 to 70 will receive either the nerve block or usu…

This study will check if certain blood markers can predict how well a nerve block procedure works for people with nerve pain. Researchers will measure pain levels and blood inflammation markers before and after the procedure in 120 adults. The goal is to see if these blood tests …

This study aims to see if a quick bedside sensory test can predict which painkiller—pregabalin, duloxetine, or a placebo—works best for people with nerve pain in their feet. About 190 adults with diabetic, chemotherapy-related, or idiopathic nerve pain will try each treatment for…

This study is collecting information from 4,000 adults with peripheral neuropathy (nerve damage) to better understand the condition. Researchers will combine standard tests with nerve ultrasound to see if it helps diagnose and track the disease. No new treatments are being tested…

This study is testing a mild electrical stimulation method on the skin to better understand nerve pain in people with neuropathy or chronic pain after surgery. Researchers will measure how pain intensity and thresholds change. The goal is to learn more about how pain signals work…

This study is collecting nerve samples and biofluids from 400 people with ALS or peripheral neuropathies to find biological markers for early diagnosis and disease tracking. By analyzing individual cells, researchers hope to identify molecular changes that happen before symptoms …

This study uses a smartphone app called SOMA to track daily mood, pain, and activity in 800 people with acute or chronic pain over four months. The goal is to find patterns that predict whether acute pain becomes chronic, or if chronic pain flares up. A smaller group will also ha…

This study looks at how spinal cord stimulation (SCS) changes certain molecules in the blood and spinal fluid of people with long-term nerve pain. Researchers will measure inflammatory markers and other signaling molecules before and after SCS in 30 adults. The goal is to underst…
