Music‐based interventions (MBIs) offer promising strategies for addressing speech‐language impairments in individuals with nonfluent aphasia. This systematic review summarizes the current literature of MBIs for nonfluent aphasia recovery by types of MBIs to determine the efficacy of MBIs and assesses the risk of bias to identify common methodological limitations. A systematic search was conducted of MEDLINE, PubMed, and APA PsycInfo for the 20 years preceding July 2024. Risk of bias assessment was performed using the revised Joanna Briggs Institute critical appraisal tool for randomized controlled trials (RCTs). Ten RCTs met the inclusion criteria, featuring MBIs such as Melodic Intonation Therapy, Modified Melodic Intonation Therapy, and singing‐based approaches. The results highlighted the potential of MBIs in various domains, particularly in enhancing repetition and naming abilities, even when compared to speech therapy. The reviewed studies exhibited a moderate to high risk of bias. Outcome measures varied widely, and functional communication, a critical rehabilitation goal, was examined in just two RCTs. Furthermore, heterogeneous control conditions and statistical methods hindered meaningful comparisons across studies. Future research should prioritize functional communication outcomes and refine intervention protocols to strengthen the evidence base. Addressing these gaps is essential for advancing the potential benefits of these clinical tools for nonfluent aphasia recovery.

Background/Objectives: Patterned Sensory Enhancement (PSE), a Neurologic Music Therapy technique, utilizes rhythm and other musical elements to facilitate functional movement in diverse clinical populations. This scoping review is the first to systematically synthesize the current evidence surrounding PSE’s use and its effects on motor function across various populations in order to evaluate its therapeutic potential, identify gaps in the existing literature, and guide future research efforts. Methods: A literature search was conducted across five major databases (MEDLINE, Embase, PsycINFO, CINAHL, and Scopus) in accordance with the PRISMA-ScR guidelines. Results: From 1018 screened articles, 15 met the inclusion criteria. PSE has been demonstrated as effective across clinical populations, including Cerebral Palsy, stroke, Parkinson’s Disease, and psychiatric conditions. However, the results for studies on geriatric populations remain inconsistent. Despite the variability in the outcome measures and movement types assessed, PSE is consistently supported as an effective approach for enhancing motor function. However, to date, only a small number of studies across populations have been conducted. Conclusions: This scoping review suggests that PSE holds significant potential for improving motor function across a range of clinical populations. Further research is needed to explore the long-term effects, use standardized terminology, and identify the optimal implementation strategies tailored to the unique needs of different populations to maximize its therapeutic benefit.
