| Description: | Sensorineural hearing loss (SNHL) children were reported to have a higher risk of developing vestibular and balance dysfunction. Therefore, an accurate and straightforward screening tool for vestibular and balance problems in SNHL children is required to determine the need for a further diagnostic assessment and early intervention. This study aimed to determine the sensitivity and specificity of the screening tool [bucket test of Subjective Visual Vertical and Horizontal (SVV) and (SVH), Dynamic Visual Acuity (DVA) and Pediatric version of Clinical Test of Sensory Interaction of Balance (pCTSIB)] by using the conventional laboratory testing [ocular and cervical vestibular evoked myogenic potential (oVEMPs and cVEMPs), video head impulse test (vHIT) and Balance Rehabilitation Unit (BRU™)] as reference tests. Thirty-four SNHL children (mean age±SD = 8.18±0.75) and normal hearing (NH) children (mean age±SD = 8.02±0.89) were recruited for this study. The data collection was conducted from March to November 2019. All subjects underwent the screening tests, and the laboratory testing was conducted within four weeks after completing the screening tests. Receiver Operating Characteristic (ROC) was performed to determine the optimal cut-off values of the screening tools. The area under the curve (AUC) for the SVV and SVH=0.81 respectively, DVA=0.84 and pCTSIB=0.92, indicating the tests' good to excellent diagnostic accuracy. The bucket test of SVV with cut-off values of 1.13 degrees demonstrated a sensitivity of 93.75% and specificity of 65.38%. The bucket test of SVH with cut-off values 1.38 showed 81.25% and 69.23% sensitivity, and specificity respectively. Seventy percent sensitivity and 86.21% specificity with cut-off values of 2.75 were obtained for the DVA test. The sensitivity and specificity of pCTSIB are 90.63% and 91.67%, respectively, with cut-off values of 9.5 for the total score of conditions five and six. All screening tests showed a statistically significant difference between both groups (p<0.05) except for condition one for pCTSIB (p>0.05). NH children showed 100% responses for cVEMPs and oVEMPs, while SNHL children obtained 52.94% and 73.53% responses, respectively. vHIT and BRU™ test showed a significant difference between SNHL and NH children (p<0.05) except for the right anterior gain value (p>0.05). In conclusion, children with SNHL showed a reduction in their vestibular and balance function compared to the NH control group. We want to suggest that the bucket test of SVV and SVH, DVA and pCTSIB has the potential to be used as vestibular and balance screening tools in primary-aged school children with SNHL.,Ijazah Sarjana Sains Kesihatan |
