ABSTRACT
Background: VEMP is a relatively diagnostic tool that is used for assessing the functioning of the inferior vestibular nerve and the structures it innervates. VEMP is recorded from tonically contracted neck muscle and from inferior extraocular muscles of the eye by acoustic stimulation are referred to as cervical VEMP (cVEMP) and ocular VEMP (oVEMP).
Need of the study: VEMP has been utilised as a good tool to assess the sacculocollic pathways. Therefore, there is a need to study the VEMP as a tool to assess the plasticity in the sacculocollic pathway. However, there is a dearth of information regarding the effect of juggling training on vestibular system, so, there is a need to study whether the training improves the neurophysiologic responses from the utricle and saccule. The present study aimed to find out the differences between cVEMP and oVEMP parameters in jugglers and nonjugglers.
Method: Total 60 participants divided into two groups such as jugglers and nonjugglers were studied for cVEMP and oVEMP in terms of latency, amplitude, interamplitude ratio and threshold. Latency was studied for P13 and N23 peaks in milliseconds. Amplitude was studied in microvolts and thresholds were studied in terms of intensity. Data was calculated separately for right ear and left ear in different intensities for cVEMP and oVEMP in terms of mean, standard deviation and effect size. The data was analysed by SPSS software version 25.0 (Windows CJ278ML, IBM computers Pvt. Ltd, 2017). For normality analysis of data, Shapiro wilk test was done. Between groups analysis was done using Wilcoxon signed rank test and Mann Whitney U-test at 95% confidence interval.
Results: The results suggested lower latencies, delayed amplitudes and equal in thresholds for both the groups. When comparison was done between the groups, the juggler group had better results in comparison to nonjuggler group. cVEMP had lower latencies and reduced amplitudes for jugglers than nonjugglers.
Conclusion: The findings of the study showed the Jugglers group had significant better result than nonjugglers group in terms of parameters of cVEMP.
Key words: cVEMP; oVEMP; jugglers.
