What the 2024 LSVT LOUD® & LSVT BIG® Research Means for You

The year 2024 marked a milestone in advancing the scientific understanding of LSVT LOUD and LSVT BIG therapies. These evidence-based treatments, designed to improve communication and motor function in individuals with neurological conditions, saw a remarkable surge in research publications.

This growing body of literature not only reinforces the efficacy of these interventions but also expands their potential applications across diverse populations and conditions. Let’s explore the highlights of this year in research.


LSVT LOUD: 10 New Studies Highlighting Efficacy and Innovation

LSVT LOUD, an intensive speech therapy program initially designed for individuals with Parkinson’s disease, received significant attention in 2024. Ten new studies explored its effectiveness across various domains, showcasing its adaptability and impact.

Key Research Highlights

  1. Large Scale Studies:
    • A systematic review by Perry et al. (2024) provided a comprehensive analysis of behavioral management techniques for respiratory and phonatory dysfunction in neurodegenerative diseases. LSVT LOUD was the only treatment with strong quality evidence for people with Parkinson’s among all therapies reviewed. 
    • Sackley et al. (2024) conducted a randomized controlled trial comparing LSVT LOUD with NHS speech therapy and no treatment. LSVT LOUD was more effective at reducing the impact of speech disorders than no speech and language therapy and the standard NHS speech therapy. The standard NHS therapy showed no evidence of benefit compared to no speech and language therapy. 
  2. Expanding Applications:
    Research explored the use of LSVT LOUD across different diagnoses, languages, and underlying mechanisms. For example:
    • Case studies demonstrated benefits for patients with progressive supranuclear palsy Sebestyen et al. (2024), primary progressive apraxia of speech Choi et al. (2024), multi-system atrophy (Hayashi et al. 2024) and laryngeal dystonia Schnell & Slavin (2024).
    • Moya-Galé et al. (2024) highlighted perceptual improvements in Spanish-speaking Parkinson’s patients following intensive voice treatment.
  3. Speech Accessibility Insights:
    Studies like those by Hasegawa-Johnson et al. (2024) examined a large corpus of dysarthric and dysphonic speech which has the potential to significantly improve speech technology for people with disabilities. This first study documented a 30% improvement in automatic speech recognition. 

LSVT BIG: 6 New Studies on Motor Function and Beyond

LSVT BIG, the physical and occupational therapy counterpart to LSVT LOUD, focuses on improving movement amplitude in individuals with Parkinson’s disease and other neurological conditions. In 2024, six new studies highlighted its versatility and effectiveness.

Key Research Highlights

  1. Parkinson’s Disease Outcomes:
    • A randomized controlled trial by Eldemir et al. (2024) explored the impact of standard and modified LSVT BIG protocols on balance and gait in Parkinson’s patients. This study demonstrated that the standard protocol outperformed the modified protocol in enhancing sensory integration and gait cycle symmetry. Nevertheless, both groups experienced comparable improvements in motor symptoms, postural stability (PS), functional mobility, and gait speed. Patient satisfaction was not measured. 
    • This randomized controlled trial by Kaya Aytutuldu et al. (2024) showed that telerehabilitation-based LSVT BIG enhanced dynamic balance, confidence, quality of life, and activity levels in early-stage patients with Parkinson’s.
    • Clarkin et al. (2024) examined impact of LSVT BIG on outcomes in individuals with Parkinson’s disease. In this case series, 8 out of 9 participants demonstrated meaningful improvements in motor function, gait speed, balance confidence, quality of life, and dynamic balance. These improvements were evident both immediately after treatment and four weeks later, highlighting the sustained impact of LSVT-BIG on functional outcomes over time.
  1. Cognitive Impairment Considerations:
    Iwai et al. (2024) found that mild cognitive impairment did not diminish the effectiveness of LSVT BIG therapy for Parkinson’s patients, highlighting its broad applicability.
  2. Applications Beyond Parkinson’s Disease:
    Hirakawa et al. (2024) explored the benefits of LSVT BIG for progressive supranuclear palsy, suggesting its potential for other movement disorders.
  3. Implementation of LSVT BIG:
    Botkin & Proffitt (2024) studied how practitioners implement the LSVT BIG® program using surveys and debriefings from 47 LSVT BIG® certified clinicians.

What These Findings Mean

The expanding research on LSVT LOUD and LSVT BIG underscores their value for individuals with neurological conditions. From improving communication to enhancing mobility, these therapies are proving to be important therapeutic tools for clinicians worldwide. The studies also highlight their adaptability across diverse populations, languages, and even delivery methods like telerehabilitation.


Looking Ahead

As we acknowledge these advancements, it is clear that the future holds even greater promise for LSVT therapies. With ongoing research exploring new applications and refining existing protocols, the potential to improve quality of life for adults and children with neurological conditions continues to grow. Congratulations to all researchers who contributed to this impressive body of work! Your dedication is paving the way for innovative treatments that make a tangible difference in people’s lives.
