This study investigates inter- and intrajudge reliability of a clinical examination of swallowing in adults. Several investigations have sought correlations between clinical indicators of dysphagia and the actual presence of dysphagia as determined by videofluoroscopy. Whereas some investigations have reported interjudge reliability for the videofluoroscopic measures employed, none have reported reliability for clinical measures. Without established reliability for rating clinical measures, conclusions drawn regarding the utility of a measure for detecting aspiration can be called into question. Results of the present study indicate that fewer than 50% of the measures clinicians typically employ are rated with sufficient inter- and intrajudge reliability. Measures of vocal quality and oral motor function were rated more reliably than were history measures or measures taken during trial swallows. There is a need to define more clearly the measures employed in clinical examinations and to be consistent in reporting reliability for clinical measures of swallowing function in future research.

“…Muscles of voice and swallowing share many similar central and peripheral neural control elements as well as a cross-system interaction with respiratory functions (Kawasaki et al,1964; McFarland and Lund,1993) that may interact with the target behavior. The idea of cross-system interactions is further supported by evidence for the co-occurrence of swallowing and voice/speech disorders within individuals (Martin and Corlew,1990; Nishio and Niimi,2004). Therefore, any training that would target one element of an oral-facial-laryngeal system may theoretically manifest beneficial effects across the entire cranial sensorimotor system.…”

Targeted exercise therapy for voice and swallow in persons with Parkinson's disease

et al. 2010

Sensorimotor deficits affecting voice and swallowing ability can have a devastating impact on the quality of life of people with Parkinson disease (PD). Recent scientific findings in animal models of PD pinpoint targeted exercise therapy as a potential treatment to reduce neurochemical loss and decrease parkinsonian symptoms. Although there may be beneficial effects, targeted exercise therapy is not a standard component of therapy for the cranial sensiromotor deficits seen in PD. In this paper we review the scientific evidence for targeted training for voice and swallowing deficits. The literature search revealed 19 publications that included targeted training for voice and only one publication that included targeted training for swallowing. We summarize 3 main findings: 1) targeted training may be associated with lasting changes in voice behavior, 2) targeted training of sensorimotor actions with anatomical or functional overlap with voice and swallowing may improve voice and swallowing to some degree, but it is unknown whether these effects endure over time, and 3) evidence regarding cranial sensorimotor interventions for Parkinson disease is sparse. We concluded that targeted training for voice and swallow is a promising but understudied intervention for cranial sensorimotor deficits associated with PD and posit that animal models can be useful in designing empirically based studies that further the science on targeted training. Targeted Physical Exercise and Parkinson DiseaseThe concept of using physical exercise to treat Parkinson disease (PD) is not new. However, interest in exercise on both research and consumer levels has recently escalated because of promising new findings from clinical and animal research (Chen et al.,2005;Fisher et al., 2008;Kurtais et al.,2008;O'Dell et al.,2007;Protas et al.,2005;Toole et al.,2005). In the animal research arena, rodent models of Parkinson disease have been created using neurotoxins such as 6-OHDA (6-hydroxydopamine) and MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine). These animal models allow preclinical manipulation of neural and behavioral signs of PD, as well as environmental and treatment variables in a systematic

“…Swallowing deficits in elderly people can lead to reduction in quality of life and are risk factors for serious health concerns, such as depression and aspiration pneumonia [56, 58]. Likewise, Parkinson disease, even in the early stages, can lead to significant swallow deficits that negatively impact quality of life [8, 11, 16-18, 35]. Major signs of parkinsonian dysphagia include reduced motility and increased transit times during the oropharyngeal swallow [17, 20, 35], delayed excursion of the base of the tongue and hyolaryngeal complex, and reduced airway sensory function [53], resulting in deficient laryngeal protection and contributing to an increased risk of airway compromise.…”

Videofluorographic Assessment of Deglutitive Behaviors in a Rat Model of Aging and Parkinson Disease

et al. 2012

Dysphagia is commonly associated with aging and Parkinson disease and can have a significant impact on a person’s quality of life. In some cases, dysphagia may be life threatening. Animal models may be used to study underlying mechanisms of dysphagia, but paradigms that allow adequate imaging of the swallow in combination with measurement of physiological variables have not been forthcoming. To begin development of methods that allow this, we used videofluorography to record the deglutition behaviors of 22 Fischer 344-Brown Norway rats in young adult (9 months old), old (32 months old), and parkinsonian (unilateral lesion to the medial forebrain bundle) groups. We hypothesized that the old and parkinsonian rats would manifest deficits in deglutition behaviors analogous to those found in human clinical populations. Our results supported our hypotheses in that the old group demonstrated reductions in bolus transport speeds and mastication rate, while the parkinsonian rats showed impairments in oral processing. Interpretation of these results should consider the particular animal model, lesion type and videoflurographic protocol used in this work. Future studies will link swallow imaging data of this kind with physiological and anatomical data in a manner not possible with human participants.
