Abstract Persistent postural-perceptual dizziness (PPPD) is a chronic disorder of perceived unsteadiness. Symptoms can be exacerbated in visually complex stationary or moving environment. Visual dependence and increased motion sensitivity are predictors for PPPD but its pathophysiology remains unknown. We hypothesized an abnormal sensory–perceptual scaling mechanism tested visual- vestibular perceptional thresholds 32 patients 28 age-matched healthy control subjects (HC). All participants...
Abstract Introduction Persistent Postural-Perceptual Dizziness (PPPD), as an umbrella term for functional dizziness, encompasses a wide range of subjective symptoms affecting visual, vestibular, and motor functions. We developed the Athens-Lübeck Questionnaire (ALQ) bedside tool to differentiate specific symptom subtypes, which could inform more targeted research into pathogenesis syndrome facilitate tailored physiotherapeutic interventions. Methods A total 96 patients with primary or...

Abstract Patients with persistent postural-perceptual dizziness (PPPD) perceive postural instability larger than the observed sway. It is unknown whether concept of misperception prevails during vestibular stimulation and it may account for unsteadiness patients complain body movements. We tested hypothesis an abnormal sensory-perceptual scaling mechanism in PPPD by recording objective, perceived, reproduced sway under various standing conditions, modulating visual proprioceptive input,...
The effectiveness of trial-and-error, graded-choice, and verbal-instruction procedures on the acquisition maintenance a two-choice simultaneous color discrimination in an intradimensional double-reversal learning situation was studied using 18 first-grade children. After acquiring red-green during one 70-trial session, discriminative roles stimuli were reversed for 30 trials, followed by second reversal trials. Children graded-choice groups acquired maintained discriminations with fewer...
