What is the purpose of this trial?

This trial explores a new approach to assist Veterans dealing with both chronic pain and depression. It combines repetitive Transcranial Magnetic Stimulation (rTMS), which uses magnets to stimulate brain activity, with Acceptance and Commitment Therapy (ACT), a type of talk therapy focused on accepting feelings and committing to personal values. Researchers aim to determine if this combination can improve daily functioning and quality of life. Veterans who have experienced long-lasting pain (pain most days for at least six months) and depression may be suitable for this study. As an unphased trial, this study offers Veterans a unique opportunity to contribute to innovative research that could enhance treatment options for chronic pain and depression.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications, but it does require no changes to your pain or mood treatment for one month before starting the trial.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that repetitive Transcranial Magnetic Stimulation (rTMS) applied to a specific part of the brain positively affects depression. In one study, more than half of the patients with treatment-resistant depression improved after two weeks of rTMS, suggesting that rTMS is generally well-tolerated. Another study found that rTMS and the medication lithium were similarly safe in preventing depression from returning in patients who had not responded to other treatments, further supporting its safety.

Acceptance and Commitment Therapy (ACT) has been researched for its benefits in managing chronic pain and depression. Reviews of these studies indicate that ACT can improve functioning with pain and reduce symptoms of depression. This evidence suggests that ACT is safe and helpful for those dealing with chronic pain and depression.

Together, these findings suggest that combining rTMS and ACT is likely to be well-tolerated. However, since this trial is in an early stage, it primarily aims to assess the practicality of this combined treatment for participants. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about combining Acceptance and Commitment Therapy (ACT) with Repetitive Transcranial Magnetic Stimulation (rTMS) for chronic pain and depression because it offers a dual approach that targets both psychological and neurological aspects of these conditions. Unlike standard medications that primarily address symptoms, ACT helps patients cope with pain and depression by promoting psychological flexibility and acceptance. Meanwhile, rTMS, particularly when applied to the dorsolateral prefrontal cortex (DLPFC), is a non-invasive technique that can modulate brain activity, potentially offering relief without the side effects associated with pharmaceuticals. This blend of therapy and stimulation could offer a holistic and more effective treatment pathway.

What evidence suggests that this trial's treatments could be effective for chronic pain and depression?

This trial will compare the effects of two different treatment combinations for chronic pain and depression. One group will receive active repetitive Transcranial Magnetic Stimulation (rTMS) targeting the dorsolateral prefrontal cortex (DLPFC) combined with Acceptance and Commitment Therapy (ACT). Research has shown that rTMS can reduce chronic pain and improve symptoms in individuals with chronic pain conditions, particularly when targeting the DLPFC. Additionally, rTMS is known for treating depression, making it a promising option for those with both chronic pain and depression. Combining rTMS with ACT may further enhance these benefits by helping individuals better manage their symptoms and improve their quality of life. Another group in this trial will receive sham rTMS combined with ACT to compare the effectiveness of the active treatment. ^{6 7 8 9 10}

Published Research Related to This Trial

In a study of 61 active-duty service members with treatment-resistant depression who underwent at least 20 sessions of repetitive transcranial magnetic stimulation (rTMS), there was a statistically significant reduction in depressive symptoms, as indicated by a decrease in average PHQ-9 scores from 15.8 to 12.6 (P < 0.001).

Approximately 69% of participants experienced a reduction in their depressive ratings, with 20% achieving a level of improvement that placed them in the nondysfunctional range, suggesting that rTMS is a promising treatment option for major depression in this population.

High-frequency repetitive transcranial magnetic stimulation (rTMS) of the primary motor cortex is definitively effective for treating neuropathic pain, while high-frequency rTMS of the left dorsolateral prefrontal cortex is effective for depression, based on a comprehensive review of literature up to 2018 involving multiple studies.

Low-frequency rTMS has probable efficacy for various conditions, including improving motor recovery in stroke and quality of life in fibromyalgia, but the overall clinical relevance of rTMS benefits may vary and is not guaranteed.

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive treatment that can provide partial and temporary relief from severe chronic pain, particularly in conditions like neuropathic pain and fibromyalgia.

While rTMS effects are generally short-lived, daily sessions over several weeks can lead to longer-lasting pain relief, and for patients who respond but later relapse, surgical options like implanted electrodes may help maintain the benefits.

A study of 77 military patients receiving rTMS treatment showed significant reductions in depression and PTSD symptoms, with over 44% of patients experiencing a notable decrease in depression scores after treatment.

Most patients had previously tried multiple antidepressants (average of 2.7 trials), indicating that rTMS may be an effective alternative for those with treatment-resistant depression and comorbid PTSD.

In a randomized controlled trial involving 142 patients, daily left prefrontal rTMS showed a significant 37% reduction in procedural pain over 15 sessions, indicating that patients may adapt to the treatment's discomfort over time.

The decrease in pain was specific to those receiving active rTMS and suggests that the stimulation itself may contribute to pain reduction, rather than just patient accommodation, which could be linked to improved clinical outcomes.
