Effectiveness of Audio-Tactile Performance Technique With Sing-Along Lyrics on Oral Hygiene Instruction to Visually Impaired Individuals

The goal of this match-pair randomized study is to compare the effectiveness of the standard Audio-Tactile Performance (ATP) technique with a song-based adaptation (ATP/S) in teaching oral hygiene in visually impaired individuals aged 6 to 20 years in Kathmandu, Nepal. 1. Can the ATP/S approach achieve a greater improvement in plaque control, as measured by the Patient Hygiene Performance (PHP) index, compared to standard ATP instruction over a two-week period? 2. Does the rhythmic structure of a song lead to a more continuous improvement in toothbrushing task performance and theoretical oral health knowledge? Researchers will compare a control group receiving standard ATP with an audio information file to an intervention group receiving ATP with a sing-along song to see if rhythmic auditory stimuli help regulate sequencing and reduce working-memory demands during complex motor tasks.
