A Controlled Study to Assess the Effectiveness of Aerobic Exercise as an Augmentation Therapy for Inpatients With Major Depressive Disorder
Recruitment status was Not yet recruiting
We will evaluate the effect of a short-term aerobic exercise program as an adjuvant treatment in patients with depression undergoing standard clinical antidepressant medication therapy as compared to the effect of stretching exercise. In addition, the effect of exercise on plasma biological markers will be examined and observed changes correlated with clinical antidepressant effects. We hypothesize that the aerobic exercise group will achieve a significantly higher response rates of depressive symptoms, will also have a greater degree of change in the plasma markers, than the control stretching group.

Primary Purpose: Treatment
|Official Title:||A Controlled Study to Assess the Effectiveness of Aerobic Exercise as an Augmentation Therapy for Inpatients With Major Depressive Disorder|
- response of depressive symptoms- reduction in HAM-D score at the end of the follow-up period
- reduction in pretreatment BDI score
- remission according to HAM-D score
- remission according to BDI score
- changes in plasmatic measurements before and after the first and last exercise
- length of hospitalization
|Study Start Date:||May 2007|
|Estimated Study Completion Date:||May 2009|
The patients will be randomly assigned to 3 weeks of augmentation therapy (in addition to the antidepressant medication, which will be continued) with either: 1) aerobic exercise or 2) stretching exercise (control group). Random assignment to each group will be stratified according to previous response to treatment as determined by a psychiatrist and review of the Antidepressant Treatment History Form (ATHF) and by gender.
Severity of depression will be rated at the first baseline visit and every week during the exercise program using the Hamilton Depression Scale (HAM-D 21 items), Clinical Global Impression Scale (CGI) (observer-rated) and Beck Depression Inventory (BDI) and Visual Analog Scale (self-rated).
Blood samples will be obtained four times during the study - before and after the first exercise session and before and after the last exercise session. The blood taken before the exercise sessions will be used to assay thyroxine, cortisol, insulin, opioid peptides and cytokines such as IL-6 and TNF-α in the plasma. The blood taken after the exercise sessions will be used to re-examine variables expected to be altered immediately after exercise such as cortisol, opioid peptides, catecholamines and cytokines.
