Effects of Normalized Short-Term Conversations on Individuals with Severe Motor and Intellectual Disabilities: A Heart Rate Study

Abstract

This study examines the impact of normalized short-term conversations on individuals with severe motor and intellectual disabilities (SMIDs), mainly focusing on changes in heart rate as an indicator of their response. Existing literature has verified the effects of stimulation and activity in even the most severe bedridden cases of SMIDs, highlighting the importance of such interactions for their quality of life (QOL). Beyond special support events, regular communication with family and friends is crucial. In this study, we conducted trials to determine how daily, short-term interactions affect individuals with SMIDs, as evidenced by changes in their heart rate. A designated individual visited each participant’s room at a set time for five minutes three times a week over two weeks. We analyzed the relationship between the median beats per minute (bpm) and the number of trials. Results showed that the median bpm increased as the trials continued in two cases, while in the other two cases, it decreased. Regression analysis indicated significant effects in all cases, suggesting that normalized communication might influence the patients’ circadian rhythms. These findings underscore the importance of daily communication for bedridden individuals with SMIDs, even if brief.
