Pain Paid Clinical Trials in Connecticut

Low back pain is a significant public health problem, is very prevalent, and is often characterized by the persistence of symptoms. Unfortunately, substantial improvements in people with chronic low back pain are rare, causing most people to live with the pain. People with chronic low back pain may have an exaggerated pain response to nociceptive input into tissues that may also cause symptoms distant from the site of the primary symptoms. Historically, these symptoms were thought to be related to pathoanatomic changes to the muscles, ligaments, or joints. However, the severity of these structural changes weakly correlates with the clinical presentation and, in most cases, is not directly related to diagnostic image findings. Patients with chronic musculoskeletal pain, in general, show signs of local/central sensitization. The central sensitization may appear to be directly correlated with the intensity and duration of pain. Therefore, it is essential to reduce pain intensity and minimize the duration of pain to prevent this from happening. Pain relief for chronic low back pain patients should be aimed at treatments that reduce central excitability and increase central inhibition. Research into chronic low back pain treatment has demonstrated strong evidence that different types of exercise decrease pain and improve quality of life. However, exercise itself may be painful, preventing a person from exercising. Thus, treatments aimed at decreasing pain will improve a person's ability to exercise and participate in activities of daily living. One treatment aimed at reducing central excitability and increasing central inhibition is transcutaneous electrical nerve stimulation (TENS). TENS is a "non-pharmacological" treatment for pain that is inexpensive, safe, and easy to use. Prior studies show that TENS utilizes opioid receptors both spinally and supraspinally to inhibit nociceptive dorsal horn neurons, reduce excitatory neurotransmitter release, and reduce hyperalgesia. Thus, TENS may be particularly useful in people with chronic low back pain because it can activate descending inhibitory pathways (reduced in chronic low back pain patients) and inhibit central excitability (increased in chronic low back pain patients). Previous studies that have investigated the effects of TENS on pain in low back pain patients have failed to use proper intensities of current, and the assessment of pain was not performed during the peak of the analgesic response. Previous studies show inadequate intensities do not reduce pain or increase pressure pain thresholds. Further, TENS typically does not affect resting pain, while changes in pressure pain thresholds and pain with movement are reduced. Thus, the current study proposes to assess the effects of TENS on measures of pain, function, and descending inhibition using the maximal tolerable intensity of TENS applied to a large area of the trunk.

The goal of this 2-cohort, cluster randomized, type 2 hybrid trial is to test the effectiveness, cost-effectiveness and patient-level effects of an implementation facilitation strategy in helping M2VA case managers adopt a Military2VA Pain Care Pathway (M2VAPCP) intervention. The main questions it aims to answer are: Will adding implementation facilitation to training-as-usual for M2VAPCP result in a higher proportion of Veterans who receive M2VAPCP compared to training-as-usual alone? Will adding implementation facilitation to training-as-usual for M2VAPCP result in better adherence to the M2VAPCP protocol compared to training-as-usual alone? Will implementation facilitation improve Veterans' clinical outcomes (pain, risky substance use) and increase the number of non-pharmacological pain treatments used compared to training-as-usual alone?

The overarching goal of this double-blind, placebo-controlled, crossover study is to characterize the pharmacokinetic (PK) and pharmacodynamic (PD) effects of the main analgesic and psychoactive constituent of cannabis, delta-9 tetrahydrocannabinol (THC), among older adults - the fastest growing population of cannabis consumers, and the most likely age cohort to use cannabinoids to relieve pain. The research will proceed with a sub-study, randomizing 20 men and women aged 65 years or older, to two doses focusing on oral THC administration and a sub-study randomizing 20 men and women aged 65 years or older, to two doses focusing on vaporized THC administration.

This study is being performed to compare the effects of three types of group-based psychological treatments delivered over video telehealth for chronic musculoskeletal pain in older U.S. military Veterans. The three types of psychological treatments are: Cognitive-Behavioral Therapy (CBT), Emotional Awareness and Expression Therapy (EAET), and Mindfulness Meditation (MM). In addition, the investigators will evaluate which patients respond best to each treatment and how each treatment works. The investigators are performing the study because chronic pain is a big problem among Veterans. Older Veterans are the focus because they have the highest rates of chronic pain, perhaps as high has 80%. The investigators are looking at psychological treatments because they are less risky than medications or procedures for older Veterans. Telehealth is an important aspect of the proposal, as delivery over telehealth could improve access to treatments. CBT is endorsed nationally by VA, but no standardized MM is available through VA, and only a few VA sites use EAET, which is a newer treatment focusing on how stress and emotions affect pain. The project aims to evaluate a standardized form of MM and the newer treatment, EAET, compared to the standard CBT used widely in VA. Read Less
