Physical Activity Programme for Adults with Treatment-Resistant Depression

Recruitment starting soon!

Study contact: PA.TRD@unityhealth.to

Overview: 

Physical activity (PA) has been associated with improvements in mood and mental health in both clinical and non-clinical populations. Recent research suggests that low doses and enjoyability of PA underlie its’ protective effect on mental health and well-being. As a result, in this study, we seek to explore the impact of a 4-week remotely delivered individualized one-on-one PA programme in addition to treatment as usual (TAU) on depressive symptoms of participants with treatment-resistant depression (TRD). At this time, we aim to conduct a pilot study with 30 participants wherein 20 will be randomized to the PA group and 10 will be in the control group. 

Inclusion Criteria: 

  • Sedentary adults (engage in less than 60 minutes of moderate-to-vigorous physical activity per week) between the age of 18 and 65 years, inclusive, capable of giving informed consent.
  • Participants meeting diagnostic criteria for major depressive disorder (MDD) without psychotic symptoms according to the Diagnostic and Statistical Manual of Mental Disorders – 5th Ed. (DSM-5) and currently experiencing a major depressive episode (MDE) as confirmed by the Mini International Neuropsychiatric Interview (MINI).
  • A Montgomery-Åsberg Depression Rating Scale (MADRS) total score of ≥ 7 at screening (mild to severe MDE).
  • Failure of at least two trials of antidepressant therapy of adequate dose and duration during the current episode as established by the Antidepressant Treatment History Form (ATHF) and self-report.
  • Receiving treatments congruent with Canadian Network for Mood and Anxiety Treatments (CANMAT) guidelines with no medication changes or no introduction of psychotherapy allowed one month before screening (28 days), during the randomized intervention phase (28 days), and during the follow-up phase (42 days).

Exclusion Criteria:

  • Current symptoms of mania, hypomania, mixed episodes, or psychosis.
  • Have received a diagnosis of alcohol or a substance use disorder within the past 3 months or as confirmed by the MINI. Other secondary psychiatric comorbidities (e.g., anxiety disorders, trauma-related disorders, etc.) will not be excluded.
  • Pregnant females.
  • Have diabetes. 
  • Acute risk for a cardiovascular event (i.e., cardiovascular event within the past 12 months). 
  • Have any medical contraindications to exercise according to the Physical Activity Readiness Questionnaire (PAR-Q).
  • Self-reported balance, gait, or locomotion difficulties that would preclude participation in a physical activity programme. 
  • Have any other condition that, in the opinion of the investigator(s), would adversely affect the subject’s ability to complete the study or its measures.
  • Have exercise-induced asthma. 
  • Taking medication that interferes with heart rate response to exercise, such as beta blockers.
  • Do not own a smartphone. 
  • Do not have reliable access to the Internet.
  • Have previously received intravenous ketamine treatment in the last 2 months.
  • Non-English-speaking individuals are excluded because the ability to communicate study information, answer questions accurately and completely about the study, and obtain consent are necessary.

Treatment Description:

  • Upon confirming eligibility in the study, participants will be randomized to the PA group (PA programme plus TAU) or the control group (no PA programme, only TAU). 
  • All participants will receive an Oura Ring which will collect passive physiological data (e.g. sleep, activity and readiness) throughout the course of the study. 
  • On a daily and weekly basis, participants will complete self-report questionnaires relevant to mental health and quality of life.
  • Participants in the PA group will meet with their program trainer once a week for 4 weeks for a supervised PA session and engage in PA outside of the supervised session. 
  • Participants will be followed up with for 6 weeks after the intervention period.
