The goal of this randomized controled trial is to test the effects of assigning people with chronic post-stroke aphasia to 12 weekly choir sessions, compared to usual care.
Interventions
BEHAVIORAL
Choir singing
The 12-week intervention will consist of 12 in-person choir-singing sessions (1 session/week, 1,5 h/session, total 18h) conducted by a choir master in addition to home training (3 x 30-minutes-sessions/week, total 18h). In total, participants will undergo the intervention for 3 hours/week for 12 weeks (i.e., 36 hours).
OTHER
Usual care
Rehabilitation services received by patients and social activities will be monitored and documented.
Primary outcome measures
Communication Index
Time frame: T1 (baseline, week 1), T2 (week 15), T3 (week 16), T4 (week 30), T5 (week 31)
The ability to communicate one's feelings and basic needs effectively / is computed by averaging the percentage scores (score/total×100) of the Communicative Activity Log (CAL) and the communication subscale of the Stroke Impact Scale 3.0 (SIS). Minimum value=0; Maximum value=100; Higher scores mean a better outcome.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
