Key result
Non-invasive neuromodulation shows potential as adjunct stuttering therapy depending on stimulation parameters and behavioral training.
Why the study?
Non-invasive neuromodulation methods have gained attention for their potential to elucidate the underlying nature of stuttering and serve as adjunct therapeutic approaches.
This review highlights the potential of non-invasive neuromodulation methods like tDCS and TMS as adjunct therapeutic approaches for stuttering intervention.
May support adjunct neuromodulation in stuttering; leaves open efficacy and parameters pending randomized trials.
Non-invasive neuromodulation methods such as transcranial Direct Current Stimulation (tDCS) and Transcranial Magnetic Stimulation (TMS), have been extensively utilized to enhance treatment efficacy for various neurogenic communicative disorders. Recently, these methods have gained attention for their potential to reveal more about the underlying nature of stuttering and serve as adjunct therapeutic approaches for stuttering intervention. In this review, we present existing research and discuss critical factors that might influence the efficacy of these interventions, such as location, polarity, intensity, and duration of stimulation, as well as the impact of combined behavioral training. Additionally, we explore implications for future studies, including the application of different neuromodulation methods to address various aspects of stuttering such as speech fluency and associated psychological and cognitive aspects in people who stutter.
