Variation in the management of dysphagia after stroke: does SLT make a difference?

Oro-facial impairment in stroke patients

Stroke is considered one of the leading causes of death and acquired disability with a peak prevalence over the age of 80 years. Stroke may cause debilitating neurological deficiencies that frequently result in sensory deficits, motor impairment, muscular atrophy, cognitive deficits and psychosocial impairment. Oro-facial impairment may occur due to the frequent involvement of the cranial nerves' cortical representation areas, central nervous system pathways or motoneuron pools. The aim of this narrative, non-systematic review was to discuss the implications of stroke on oro-facial functions and oral health-related quality of life (OHRQoL). Stroke patients demonstrate an impaired masticatory performance, possibly due to reduced tongue forces and disturbed oral sensitivity. Furthermore, facial asymmetry is common, but mostly discrete and lip restraining forces are reduced. Bite force is not different between the ipsi- and contra-lesional side. In contrast, the contra-lesional handgrip strength and tongue-palate contact during swallowing are significantly impaired. OHRQoL is significantly reduced mainly because of the functional impairment. It can be concluded that impaired chewing efficiency, dysphagia, facial asymmetry, reduced lip force and OHRQoL are quantifiable symptoms of oro-facial impairment following a stroke. In the absence of functional rehabilitation, these symptoms seem not to improve. Furthermore, stroke affects the upper limb and the masseter muscle differently, both, at a functional and a morphological level. The rehabilitation of stroke survivors should, therefore, also seek to improve the strength and co-ordination of the oro-facial musculature. This would in turn help improve OHRQoL and the masticatory function, subsequently preventing weight loss and malnutrition.

Gastrointestinal complications after ischemic stroke

Ischemic stroke is an important cause of morbidity and mortality, and currently the leading cause of adult disability in developed countries. Stroke is associated with various non-neurological medical complications, including infections and thrombosis. Gastrointestinal complications after stroke are also common, with over half of all stroke patients presenting with dysphagia, constipation, fecal incontinence or gastrointestinal bleeding. These complications are associated with increased hospital length of stay, the development of further complications and even increased mortality. In this article we review the epidemiology, pathophysiology, diagnosis, management and prevention of the most common gastrointestinal complications associated with ischemic stroke.

Assessing swallowing disorders online: a pilot telerehabilitation study

OBJECTIVE

Dysphagia (a swallowing disorder) is known to occur in numerous clinical populations, but unfortunately because of issues accessing speech pathology services, not all patients are able to receive dysphagia intervention and rehabilitation services in a timely manner. Existing research supports the use of telehealth technology for providing various aspects of speech pathology service; however, to date there is limited evidence to support the utilization of telerehabilitation in the assessment and management of dysphagia. The aim of this research was to provide pilot information on the basic feasibility and validity of conducting dysphagia assessments via telerehabilitation.

MATERIALS AND METHODS

Ten simulated patients, actors portraying patients with a range of swallowing difficulties, were used rather than actual patients to minimize any potential patient risk from unidentified aspiration. Dysphagia was assessed simultaneously by a face-to-face (FTF) and telerehabilitation speech pathologist (T-SP). Each simulated patient was assessed using a Clinical Swallowing Examination (CSE) protocol that was modified to suit a telerehabilitation environment. The CSE was administered with the support of an assistant via an Internet-based videoconferencing telerehabilitation system using a bandwidth of 128 kilobits per second.

RESULTS

Results revealed high to excellent levels of agreement between the T-SP and the FTF-SP across all parameters of the CSE. Agreement for aspiration risk was excellent.

CONCLUSION

The pilot data indicate that the current model of administering a CSE via telerehabilitation has potential to be a feasible and valid method for the remote assessment of swallowing disorders.
