Próba wykonalności ćwiczeń jako strategii początkowej w leczeniu RTMS w trudnej do leczenia depresji

28 września 2026 zaktualizowane przez: Sara Tremblay, The Royal Ottawa Mental Health Centre

Randomizowane badanie oceniające wykonalność ćwiczeń jako strategii podstawowej w leczeniu RTMS w trudnej do leczenia depresji

The goal of this study is to collect feasibility data on combining structured exercise aimed to improve physical fitness, and intermittent TBS (iTBS) in treating individuals diagnosed with difficult-to-treat depression who are physically inactive. By conducting this trial, we will compare the therapeutic benefits of the combined approach against the standard treatment of iTBS alone (without exercise). These findings will be used to inform future large-scale projects in which we will investigate, in a larger sample size, whether structured exercise aimed to improve fitness as recommended by most public exercise guidelines (i.e., ≥3x/week, moderate-to-vigorous intensity) serves as an active ingredient that amplifies the effectiveness of iTBS. Ultimately, the insights gained from this study will be valuable for clinicians seeking to alleviate depressive symptoms in MDD through neuromodulation techniques such as iTBS.

Szczegółowy opis

This is a randomized, two-arm, pilot feasibility clinical trial design involving physically inactive individuals diagnosed with treatment-resistant depression (TRD). Participants will be randomly assigned to either: 1) 4-weeks of exercise (moderate-to-vigorous intensity; ~1h session, 3x/week) followed by 6 weeks of iTBS combined with exercise (intervention group), or 2) 4 weeks of stable treatment (i.e. no change in psychotropic medication/psychotherapy regimen or physical activity) followed by 6 weeks of iTBS alone (control group). The intervention group is divided into two phases: the priming phase and the synergetic phase. Due to the neuroplasticity-enhancing effects of exercise and fitness, and based on pilot results demonstrating superior antidepressant effects of TBS in physically active participants, the main objective of the priming phase is to enhance brain plasticity mechanisms through increases in fitness from the 4 weeks of exercise training. In other words, this phase aims to build capacity for a better response to TBS treatment. The synergetic phase (interventional group) follows the priming and involves integrating TBS treatment into the exercise training regimen. Participants in the interventional group will maintain their exercise routine to enhance and sustain gains while undergoing TBS treatment for 6 weeks. In accordance with the recommended guidelines for both exercise and TBS treatment for depression, participants in the interventional group will engage in exercise sessions lasting approximately 1 hour, three times per week. In both interventional and control groups, TBS treatment will be administered five times per week, with treatment delivery lasting 3 minutes. We hypothesize that all aspects of this project will be feasible, that is the exercise and iTBS delivery and outcomes assessment. Additionally, we expect participants to show high levels of adherence and compliance with the strategy. The ultimate goal, to be investigated in a larger-scale study following this one, is to determine whether exercise acts as an active ingredient that enhances the effectiveness of iTBS.

Assessing feasibility on combining structured exercise and intermittent Theta Burst Stimulation (iTBS) in participants with treatment-resistant depression (TRD)
Ramy czasowe: Assessed at the end of the study once all participants have completed the study.

Feasibility outcomes are crucial metrics that will guide the refinement of our protocols, thereby enhancing our preparedness for future design endeavors. These will include: 1) recruitment, 2) adherence, 3) compliance, 4) retention, 5) satisfaction, and 6) adverse events.
Assessed at the end of the study once all participants have completed the study.
Compare the effects on clinical response of exercise on enhancing iTBS treatment efficacy vs. iTBS alone
Ramy czasowe: Administered at screening, before iTBS treatment course (week 4), at the end of the treatment course (week 10), then at the 6-week follow-up (week 16)

Clinical response will be defined as a ≥ 50% reduction in the 17-item Grid Hamilton Rating Scale for Depression (Grid-HRSD-17). The Grid HRSD is a clinician-rated instrument with seventeen items used to measure the severity of depressive episodes. The overall score ranges from 0 to 52, where scores of 0 to 7 are considered as being normal, 8 to 16 suggest mild depression, 17 to 23 moderate depression, and scores ≥ 24 indicate severe depression.
Administered at screening, before iTBS treatment course (week 4), at the end of the treatment course (week 10), then at the 6-week follow-up (week 16)
