Clinical Effectiveness of Multimodal Exercise Combined With Supportive Music and Imagery in the Management of Poststroke Mood Disorders.

The study did not have separate control groups for the exercise component or the music component alone, so it is impossible to know if the benefits came from the combination or just one part. The sample size calculation suggested 72 participants, but the study enrolled 200, which may indicate a mismatch between the planned and actual power. The authors note the sample size was small in the conclusion, despite enrolling 200 patients. Blinding of participants and personnel to the intervention was not described, which is difficult in behavioural trials but can influence subjective outcomes like self-reported mood.

The authors declared no conflicts of interest. The study was approved by the ethics committee of their hospital.

Do not assume the multimodal exercise and music imagery are the sole cause of the improvement. The observation group also received conventional nursing care, and the control group received the same care. Since there were no groups receiving only exercise or only music, the contribution of each component cannot be separated from the other or from the standard care.
