Is Neuromuscular Electrical Stimulation Effective in Treating Severe Dysarthria: Insights from a Case Study.

BACKGROUND: Dysarthria refers to a group of disorders resulting from disturbances in neuromuscular control over the speech mechanisms due to damage of the central nervous system (CNS) or peripheral nervous system (PNS). Rehabilitation outcomes of dysarthria significantly depend on the collaboration skills of the patients. This case study aimed to investigate the potential role of neuromuscular electric stimulation (NMES) in improving severe dysarthria. An 18-year-old man affected by severe dysarthria following postanoxic brain injury underwent two different intensive rehabilitation trainings: conventional rehabilitation alone, followed by NMES training alone. We evaluated patient articulation function before and after each training. The overall NMES program was scheduled in daily sessions of 30 minutes, six days a week, for four consecutive weeks. The patient did not report any side effects either during or following both types of intensive rehabilitation training. However, a clear reduction of dysarthria severity was observed only after the NMES training. CONCLUSION: NMES could allow for improved articulator expression and vocal parameters, thus enhancing communication skills, when conventional articulation treatments are not possible or are ineffective.

A case report on crossed aphasia in dextrals: Consideration about clinical features and neural network.

RATIONALE: The term crossed aphasia in dextrals (CAD) describes aphasia following a right hemisphere lesion in right-handed subjects. The diagnostic criteria for CAD, defined on the basis of clinical cases observed over the years, are aphasia; lesion in right hemisphere; strong preference for right hand use without familial history of left handedness; structural integrity of left hemisphere; and absence of brain damage in childhood. The studies of CAD have mainly been focused on the neurobiological mechanisms underlying the functional neurocognitive lateralization and organization of the brain, such as a dissociation between language and handedness, language and praxis, or other cognitive functions.Patient concerns: We described a case of a patient affected by an aphasic syndrome following cerebral hemorrhage located in right hemisphere. DIAGNOSIS: Considering the correlation between clinical data and instrumental investigations such as magnetic resonance imaging, we diagnose the patient with non-fluent aphasia. Specifically, the patient came to our attention showing a trans-cortical mixed aphasia that, later, developed in a trans-cortical motor aphasia. Contrary to most cases of CAD, our patient does not show apraxia and visuo-spatial neglect. Interventions language and visual attention when latter functions are related to right hemisphere. INTERVENTIONS: The rehabilitation program consisted in exercises stimulating verbal fluency, comprehension, reading, and writing. OUTCOMES: After 5 months of rehabilitation patient showed significant improvement in comprehension and absence of echolalia. LESSONS: At present there is no agreement about pathogenesis of CAD and neural mechanism is still unclear. Considering the clinical symptomatology, we can argue that we observed a non-fluent aphasia. However, a more large sample should be studied to asses the role of brain circuits.
