Teledynamic evaluation of oropharyngeal swallowing.

PURPOSE: The objective of the present investigation was to test the feasibility and clinical utility of a real-time Internet-based protocol for remote, telefluoroscopic evaluation of oropharyngeal swallowing. METHOD: In this prospective cohort study, the authors evaluated 32 patients with a primary diagnosis of stroke or head/neck cancer. All patients participated in 2 separate fluoroscopic swallowing evaluations--one traditional on site and one telefluoroscopic off site--through the use of a telemedicine system. Agreement between sites was tested for 3 categories of variables: (a) overall severity of swallowing difficulty, (b) presence and extent of laryngeal penetration and aspiration as rated by the 8-point Penetration-Aspiration scale, and (c) treatment recommendations. RESULTS: Results showed overall good agreement in subjective severity ratings (κ = 0.636) and in Penetration-Aspiration scale ratings (mean absolute difference = 1.1 points) between the onsite and offsite clinicians. Agreement in treatment recommendations was moderate to high, ranging from 69.3% to 100%. CONCLUSIONS: The present study supports the feasibility and clinical utility of a telemedicine system for evaluating oropharyngeal swallowing. Given the difficulty and expertise needed to complete such evaluations, this study offers promising clinical avenues for patients in rural, remote, and underserved communities and countries where expert swallowing specialists are not available.

Patient versus partner perception of voice handicap.

The primary purpose of this study was to compare patient's and communication partner's perceptions of handicap secondary to dysphonia. A secondary purpose was to compare patient health-related quality of life (HRQOL) to that of speakers with normal voice. Participants were 20 adults (mean age=69.15 years) with dysphonia and their communication partners. Patients completed the Voice Handicap Index (VHI), a questionnaire of self-perceived voice handicap, and the Short-Form 36 (SF-36), a general health questionnaire. Partners completed the Voice Handicap Index-Partner (VHI-P), a questionnaire derived from the VHI for this pilot study, to gauge partner perception of voice handicap. Patients in this study viewed themselves as only moderately handicapped by their dysphonia and their partners were in close agreement. Patients and their partners were also in close agreement on each of three VHI subscales (physical, functional, and emotional), and in all cases the physical domain was perceived by both patients and their partners to be most handicapped. Patients had lower SF-36 mean scores than those of persons with normal voice from the general U.S. population on scales assessing physical functioning, physical role, general health, vitality, social functioning, emotional role, and mental health. The results of this study are consistent with previous studies examining patient-partner agreement, which consider proxy ratings to be a useful alternative or collaborative source of patient's self-perception. Further research regarding the reliability of patient and partner agreement is necessary to most effectively assess and manage patients with dysphonia.
