Development and Pilot Testing of Virtually Simulated Intervention for Patients Having Stuttering

Sponsor: Riphah International University

Summary

This study aims to develop and pilot test a culturally appropriate virtual reality (VR)-based speech restructuring intervention for individuals with stuttering in Pakistan. During the development phase, five VR scenarios representing common real-life communication situations will be designed using a structured development process, including scenario generation, storyboarding, live-action role plays, expert review, and standard operating procedure (SOP) development. The scenarios will incorporate graded difficulty levels, speech restructuring practice, relaxation exercises, interactive avatars, and realistic audiovisual elements. Following development, a pilot study will be conducted with 10 participants with stuttering aged 13-35 years to evaluate the feasibility, usability, and preliminary effectiveness of the intervention. Participants will receive 16 therapy sessions using the VR scenarios, with assessments conducted before and after the intervention to measure changes in stuttering severity, speech fluency, communication attitudes, associated motor behaviors, physiological factors, and sense of presence within the virtual environment. Findings from the pilot study will be used to refine the intervention before conducting a larger clinical trial.
