Prevalence of Phantom Vibrations and Ringing Syndrome, and its Association with Smartphone Addiction among Medical Students of Teaching Hospital, South India.

Abstract

Introduction: Phantom vibration syndrome (PVS) and phantom ringing syndrome (PRS) is a false sensation of phone vibration and ringing when it is not. This study aimed to estimate the prevalence of PVS/PRS among medical students and to determine factors including level of smartphone usage associated with the development of phantom sensations.

Methods: Using cross-sectional analytical design, sociodemographic details, information on phantom sensations and phone usage among medical students in our institution in Puducherry, India, was obtained. Stratified random sampling strategy was incorporated to achieve a sample size of 369. Also, overuse of phone was assessed using Smartphone Addiction scale - short version (SAS-SV). Prevalence of PVS and PRS was summarized as a proportion with a 95% confidence interval (CI). Prevalence ratio for the factors associated with the phantom syndrome (PVS/PRS) was estimated using log-binomial regression.

Results: Using data from 383 students, the prevalence of phantom syndrome (PVS/PRS) was 44.9% (39.9-50.0%). PVS was more prevalent than PRS (27.9% vs 21.2%). There was a significant difference in SAS-SV scores between those with the phantom syndrome and those without. Students who stay in hostel (aPR = 1.88; 95% CI: 1.46 to 2.43), self-reported overuse of phone (aPR = 1.96; 95% CI: 1.56 to 2.45) and higher smartphone addiction score (aPR = 1.26; 95% CI: 1.04 to 1.53) were found to be significant determinants to have PVS/PRS.

Conclusion: Overall, one in two medical students had either PVS or PRS in our institution, Puducherry. Higher smartphone usage was a significant predictor of the presence of PVS/PRS.
