Conversational Therapy through Semi-Immersive Virtual Reality Environments for Language Recovery and Psychological...

Area of Science:

• Neuroscience
• Speech-Language Pathology
• Rehabilitation Medicine

Background:

• Aphasia, a disabling language disorder from brain damage, often results in persistent impairments despite traditional therapies.
• Conventional therapies (CT) for aphasia show limitations, necessitating innovative approaches for enhanced patient recovery.
• Virtual reality (VR) is emerging as a tool for more pragmatic aphasia rehabilitation.

Purpose of the Study:

• To investigate the efficacy of virtual reality (VR) conversational therapy compared to conventional therapies (CT) for chronic persons with aphasia (PWA).
• To assess the impact of VR therapy on language skills, communication efficacy, self-esteem, and quality of life.
• To explore the distribution of treatment benefits across cognitive and psychological domains.

Main Methods:

• Thirty-six chronic PWA were randomized into two groups: VR therapy and CT.
• Both groups received conversational therapy twice weekly for six months.
• A comprehensive neuropsychological battery assessed language, communication, self-esteem, and quality of life pre- and post-treatment.

Main Results:

• No significant between-group differences were observed immediately post-treatment.
• The VR group demonstrated significant within-group improvements in oral comprehension, repetition, and written language tasks.
• The VR group also showed significant gains in self-esteem, emotional state, and mood.

Conclusions:

• VR therapy enhances language recovery and psychosocial well-being in persons with aphasia.
• VR treatment offers greater distribution of benefits across cognitive and psychological aspects compared to CT.
• The findings support the ecological validity and feasibility of VR for comprehensive aphasia rehabilitation.
