Expressive aprosodia, caused by right-hemisphere brain damage, is the inability to change one's voice to express common emotions like joy, anger, and sadness. This study investigated two treatments for expressive aprosodia: cognitive-linguistic and imitative.

Participants received the treatments in random order with a 1-month break between treatments. Statistical analysis confirmed that treatment effects were modest to substantial and that 12 participants responded to at least one treatment.

Of the six participants who responded to treatment and were available for a 3-month follow-up, four continued to show treatment benefits.

Regardless of which treatment came first, the first treatment usually had larger effects than the second treatment.

Because aprosodia can cause miscommunication with friends and family, effective treatments may improve quality of life for veterans with this condition.
