[The role of oropharyngoesophageal scintigraphy in the assessment of dysphagia in neurological patients.] / Ruolo dello studio scintigrafico del transito orofaringoesofageo nella valutazione della disfagia nei pazienti affetti da patologia neurologica.

PURPOSE: The aim of this study was to assess the role of oropharingoesophageal scintigraphy (OPES) in the management of neurological patients, investigating the clinical value of semiquantitative analysis. MATERIALS AND METHODS: We enrolled 39 neurological patients clinically evaluated and scored according to the Dysphagia Outcome Severity Scale (DOSS) scale who underwent fibrolaryngoscopic swallowing examination (FEES) and OPES using a 99mTc-nanocolloid-radioblabelled semiliquid bolus. We calculated the following semiquantitative parameters: Oral Transit Time (OTT), Pharyngeal Transit Time (PTT), Esophageal Transit Time (ETT), Retention Index (RI), and Esophageal Emptying Rate (EER10s). Differences in OPES semiquantitative parameters between patients classified according to the DOSS scale were performed using the nonparametric Mann-Whitney U test. Optimal semiquantitative parameters cut-off values that correlated with DOSS classification were investigated with ROC curves. The agreement between OPES, FEES and DOSS results was measured using Cohen's Kappa test (K). RESULTS: A significantly higher OTT (p=0.028), PTT (p=0.011) and ETT (p=0.030) and lower EER10s (p=0.016) values were identified. Moderate agreement resulted between OPES and DOSS results (k=0.429, 95%CI: 0.143-0.715, p=0.002). CONCLUSIONS: Our study revealed a significant correlation between clinical dysphagia graded using DOSS scale and semiquantitative parameters obtained by OPES evaluation. Despite reliable and reproducible OPES results, allowing an adequate study also of the esophageal phase, nowadays scintigraphic study remains an underestimated method to be considered in the diagnosis of dysphagia and related complications.

Assistive technology to help persons in a minimally conscious state develop responding and stimulation control: Performance assessment and social rating.

BACKGROUND: Post-coma persons in a minimally conscious state (MCS) and with extensive motor impairment and lack of speech tend to be passive and isolated. OBJECTIVE: This study aimed to (a) further assess a technology-aided approach for fostering MCS participants' responding and stimulation control and (b) carry out a social validation check about the approach. METHODS: Eight MCS participants were exposed to the aforementioned approach according to an ABAB design. The technology included optic, pressure or touch microswitches to monitor eyelid, hand or finger responses and a computer system that allowed those responses to produce brief periods of positive stimulation during the B (intervention) phases of the study. Eighty-four university psychology students and 42 care and health professionals were involved in the social validation check. RESULTS: The MCS participants showed clear increases in their response frequencies, thus producing increases in their levels of environmental stimulation input, during the B phases of the study. The students and care and health professionals involved in the social validation check rated the technology-aided approach more positively than a control condition in which stimulation was automatically presented to the participants. CONCLUSIONS: A technology-aided approach to foster responding and stimulation control in MCS persons may be effective and socially desirable.

Objective Assessment of the Rheological Muscle Property in the Treatment of Fibromyalgia.

Fibromyalgia (FM), clinical condition characterized by several signs and symptoms such as widespread pain, trigger point, morning stiffness and extreme tiredness for scarce hours of sleep, is linked to several changes in several brain neurotransmitters, particularly serotonin and norepinephrine. Consequently, the Neural Vegetative System works more and so it generates an exaggerated muscular contraction, sweating and constriction of blood vessels. The aim of our study was to treat a selected group of female patients suffering from FM with duloxetine with physiotherapy. We used two clinical scales (VAS and FIQ) and an objective evaluation such as myometric. The analysis of the data Myoton used during any inspection showed a statistically significant reduction in the values of muscle tone in each district analyzed. This finding was also confirmed by the patients themselves who have experienced a significant welfare and less muscle tension in different locations, as evidenced by data obtained from the clinical scales used by us. In addition, our patients were thought to be satisfied with the improvements not only subjective, but also with the objective witnessed myometry, making them a share of the study and feeling constantly monitored for treatment aimed at a real reduction in muscle stiffness. In conclusion, our study demonstrates combined treatment duloxetine- physiotherapy effectively reduces a symptom often disabling and particularly troublesome in patients with FM as the exaggerated muscle contraction.

Promoting adaptive behavior in persons with acquired brain injury, extensive motor and communication disabilities, and consciousness disorders.

These two studies extended the evidence on the use of technology-based intervention packages to promote adaptive behavior in persons with acquired brain injury and multiple disabilities. Study I involved five participants in a minimally conscious state who were provided with intervention packages based on specific arrangements of optic, tilt, or pressure microswitches (linked to preferred environmental stimuli) and eyelid, toe and finger responses. Study II involved three participants who were emerging from a minimally conscious state and were provided with intervention packages based on computer presentations of stimulus options (i.e., preferred stimuli, functional caregiver's procedures, and non-preferred stimuli) and pressure microswitches to choose among them. Intervention data of Study I showed that the participants acquired relatively high levels of microswitch responding (thus engaging widely with preferred environmental stimuli) and kept that responding consistent except for one case. Intervention data of Study II showed that the participants were active in choosing among preferred stimuli and positive caregivers' procedures, but generally abstained from non-preferred stimuli. The results were discussed in terms of the successful use of fairly new/infrequent microswitch-response arrangements (Study I) and the profitable inclusion of functional caregiver's procedures among the options available to choice (Study II).
