     View Summary

    OBJECTIVE: There are a lack of disaster preparedness measures that target populations with dysphagia. In particular, disaster response plans frequently overlook differences in textures between emergency foods and regularly consumed foods. The aim of this study was to estimate the number of community-dwelling elderly care recipients requiring specific food preparations, including the population at risk of aspiration when solely consuming common emergency foods. DESIGN: A cross-sectional study. PATIENTS: Community-dwelling elderly care recipients who were certified by the public long-term care insurance system in Japan and registered at one of 77 care managing offices in Shinjuku city. METHODS: Special needs regarding food intake and risks associated with receiving emergency foods were assessed by government-certified care managers. RESULTS: Data were acquired from 1,271 care recipients. Notably, 23.1% of the sampled population had special needs regarding food intake at all times (e.g. non-oral intake or need for texture-modified foods). An additional 11.5% were estimated to experience difficulty when ingesting common emergency foods, despite the ability to consume regular foods. CONCLUSION: A relatively large portion of community-dwelling elderly people will be at risk of aspiration due to the intake of commonly distributed emergency foods following a disaster. Appropriate preparation based on an assessment of special needs regarding food intake is therefore required when planning for future disasters.

  • Development of Shoulder Exoskeleton Toward BMI Triggered Rehabilitation Robot Therapy

    © 2018 IEEE. Since exoskeletons show potential for rehabilitation therapy, many scientists have been designing upper extremity exoskeletons. Unfortunately, few have successfully provided a shoulder exoskeleton for severe impairment. Toward Brain-Machine-Interface (BMI) rehabilitation robot therapies for severe upper extremity impairment, this paper introduces a shoulder exoskeleton robot with a modular joint and an off-board modular actuator. We applied a Modular Exoskeletal Joint (MEJ) to a shoulder exoskeleton that was driven by Pneumatic Artificial Muscles (PAMs) transmitted by a Bowden cable. Our objective is generating passive movements triggered by BMI. Since large torque has to be generated for assist a whole arm, we newly designed a more powerful Nested-cylinder PAMs (NcPAMs) than our previous work. As a proof of the concept of the mechatronics design, we show the tracking performance of the periodic trajectory of a joint angle with both human and mannequin arms as simulated impairments. Our result shows that the tracking error is sufficiently small in all of the conditions and that our developed shoulder exoskeleton is an adequate substitute for flexion/extension movements.

  • Predictors for achieving oral intake in older patients with aspiration pneumonia: Videofluoroscopic evaluation of swallowing function

    © 2018 Japan Geriatrics Society Aim: Pneumonia is a common disease that is often fatal, particularly in older persons. Dysphagia is known to be closely associated with aspiration pneumonia, and hospitalized patients with aspiration pneumonia often have difficulty with oral intake. However, the relationship between acquisition of oral intake and detailed swallowing data has not been explored. The purpose of the present study was to examine the predictors, including videofluoroscopic swallowing evaluation, for achieving oral intake in older patients with aspiration pneumonia. Methods: This study included older patients, aged ≥65 years, who were admitted to Kawasaki Municipal Hospital (Kawasaki, Japan) from April 2012 through March 2014 as a result of aspiration pneumonia. Factors likely related to oral intake, including swallowing, nutritional, metabolic, and functional status, pneumonia severity and comorbidities were extracted from the medical records. Multiple logistic regression analysis was carried out to identify independent predictors for acquisition of oral intake. Results: A total of 160 patients were assigned to either the “oral intake” group (n = 104) or the “non-oral intake” group (n = 56). Multiple regression analysis showed that a low penetration aspiration scale on videofluoroscopy using 3 mL of moderately thick liquid water with tilting 30–60°, high albumin values, short duration of non-oral intake and a high Food Intake Level Scale score before admission were significantly associated with achievement of oral intake. Conclusions: Aspiration on videofluoroscopy, swallowing status before admission, nutritional status and duration of non-oral intake are important factors for acquiring oral intake. These results might be helpful for the management of older patients with aspiration pneumonia. Geriatr Gerontol Int 2018; 18: 1469–1473.

  • Long-term follow-up of dysphagia in adult patients with Duchenne muscular dystrophy

    © 2018 European Paediatric Neurology Society Background: Dysphagia is a well-known dysfunction in patients with Duchenne muscular dystrophy (DMD), but long-term follow-up of this symptom has not been reported. The aims of this study were to investigate swallowing status, prospectively study the prognosis of swallowing function in adult patients with DMD over the course of 6 years, and to identify clinical factors related to prognosis. Methods: Participants were 81 patients with DMD. Swallowing status was assessed using the Neuromuscular Disease Swallowing Status Scale (NdSSS) every 2 years for 6 years. Results: NdSSS was related to age, functional ability assessed using the Swinyard staging and the status of ventilator dependence. Median NdSSS changed from 6 to 4, 4 and 3 over the 4 time points. Number of patients with tube feeding increased by 5–10% every 2 years. Initial NdSSS was a predictor of future swallowing status. Conclusion: Swallowing status declined over time in patients with adult DMD, with initial NdSSS as a predictor.

  • A comparison of swallowing dysfunction in Becker muscular dystrophy and Duchenne muscular dystrophy

    © 2017 Informa UK Limited, trading as Taylor & Francis Group. Purpose: Swallowing dysfunction has been reported in Duchenne muscular dystrophy (DMD), but has not been studied in Becker muscular dystrophy (BMD). The aims of this study were to report the characteristics of swallowing dysfunction in BMD compared with DMD. Materials and methods: The study participants were 18 patients with BMD and 18 patients with DMD. All the patients were examined using videofluorography during swallowing of 5 mL of fluid. The penetration–aspiration scale (P–A scale) and the videofluorographic dysphagia scale (VDS) were used to evaluate dysphagia. Results: Swinyard functional ability stage was not significantly different between the BMD and DMD groups. Rate of aspiration, P–A scale score, and total VDS score did not differ across groups, but the VDS item score for laryngeal elevation was lower in the BMD group than in the DMD group (median scores 4.5 and 9, respectively; p < 0.001). In the BMD group, total VDS score significantly correlated with Swinyard stage (r = 0.78, p < 0.001), but not with age or lung function. Conclusion: Patients with BMD have swallowing problems similar to those observed in patients with DMD when matched according to physical functional status. These patients should be evaluated and followed-up for the duration of their disease. Implications for rehabiliation Dysphagia is one of the most critical problems in patients with progressive neuromuscular disease but dysphagia in patients with Becker muscular dystrophy (BMD) was not well known. Eighteen patients with BMD and 18 patients with Duchenne muscular dystrophy were examined with videofluorography. Patients with BMD have swallowing problems similar to those observed in patients with DMD.
