Development of an oral function assessment index using portable near-infrared spectroscopy for frailty assessment
Description: We developed an index combining both infrared thermography and near-infrared spectroscopy as an index of oral function for use in the assessment of frailty, and investigated its accuracy. In evaluating the effects of salivary gland massage, the index detected the decrease in oxyhemoglobin (Oxy-Hb) in response to a cold challenge and the increase in Oxy-Hb as a result of salivary gland massage. These methods may provide a comprehensive evaluation of changes in masticatory support function and its adaptability.We will therefore continue to liaise with the developers and undertake the necessary investigations to resolve these issues. We reached the final stages of system development, and are aware that studies must be undertaken to investigate the association with the actual saliva flow rate as well as studies in elderly patients with dry mouth.
