Floating Ball Voice Therapy: Preliminary Effects on Outcomes and Predicting Individual Patient Differences in Generalization.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeFloating ball voice therapy (FBVT) is a voice-controlled virtual environment based on a common treatment component across multiple evidence-based therapies: improved vocal efficiency (target) via practicing voicing with modified resonance and airflow (ingredient). This study preliminarily tested FBVT's effects on outcomes and the potential for its novel variability metrics to predict individual patient generalization.
methodTen patients with nonphonotraumatic vocal hyperfunction (NPVH) practiced FBVT for 10 days. Outcomes were assessed by a vocal efficiency ratio, a validated NPVH index, the patient-reported Voice-Related Quality of Life (V-RQOL), and forced-choice auditory judgments of overall severity. Exploration in early practice (Day 1) was estimated by how the patient's two-dimensional variability (mean airflow and intensity) related to error (difference between the patient-produced and normative vocal efficiency ratio). Generalization from the game to spontaneous speech was evaluated using the validated NPVH index.
resultsTen days of FBVT were associated with improved vocal efficiency (Cohen's
conclusionsA relatively small dosage of FBVT (i.e., 10 practice sessions) was associated with multiple improved voice therapy outcomes. The FBVT variability metrics on Practice Day 1 demonstrated strong potential to predict which patients generalized to connected speech. Future work can more thoroughly evaluate effects on outcomes and characterizing the quality of vocal exploration with a larger patient population.
