Oral hygiene is an essential aspect of inpatient care, particularly for patients with limited mobility. A toothbrushing table has been developed as an ergonomic innovation to support patients in performing oral hygiene independently. This study aims to examine the validity and reliability of a questionnaire measuring patient perceptions of the suitability of the toothbrushing table, based on Garvin’s (1987) Conformance dimension, and to analyze the relationship between patient anthropometric data and perceived suitability of the device. A quantitative approach was employed with a sample of 32 inpatients. The instrument consisted of 8 Likert-scale items (1–5). Validity was tested using Pearson correlation, reliability with Cronbach’s alpha, and the relationship between anthropometry and perception was analyzed using Spearman correlation.Results indicated that all questionnaire items were valid (r-values 0.589–0.645 > r-table 0.349; p < 0.05) and reliable (Cronbach’s alpha = 0.874). Descriptive analysis yielded a mean of 32.19, median of 33, modes of 27 and 35, and a standard deviation of 3.86. Spearman correlation revealed a moderately strong positive relationship between elbow height and total score (? = 0.61), as well as between oral cavity height and total score (? = 0.64). In conclusion, the questionnaire instrument is both valid and reliable, and the toothbrushing table is proven to conform to the anthropometric dimensions of inpatients. Further research is recommended to expand the sample size, conduct factor analysis to strengthen construct validity, and integrate clinical data to enhance the practical application of ergonomic healthcare device design.Downloads
