Purpose: Long-term care (LTC) residents with cognitive impairments frequently experience limited mobility and participation in preferred activities. Although a power wheelchair could mitigate some of these mobility and participation challenges, this technology is often not prescribed for this population due to safety concerns. An intelligent power wheelchair (IPW) system represents a potential intervention that could help to overcome these concerns. The purpose of this study was to explore a) how residents experienced an IPW that used three different modes of control and b) what perceived effect the IPW would have on their daily lives.Materials and methods: We interviewed 10 LTC residents with mild or moderate cognitive impairment twice, once before and once after testing the IPW. Interviews were conducted using a semi-structured interview guide, audio recorded and transcribed verbatim for thematic analyses.Results: Our analyses identified three overarching themes: (1) the difference an IPW would make, (2) the potential impact of the IPW on others and (3) IPW-related concerns.Conclusions: Findings from this study confirm the need for and potential benefits of IPW use in LTC. Future studies will involve testing IPW improvements based on feedback and insights from this study.
- Implications for rehabilitation
Intelligent power wheelchairs may enhance participation and improve safety and feelings of well-being for long-term care residents with cognitive impairments.
Intelligent power wheelchairs could potentially have an equally positive impact on facility staff, other residents, and family and friends by decreasing workload and increasing safety.

Recent reports show strikingly high prevalence of diabetes among urban Asian Indians; however, there are very few studies comparing urban, peri-urban and rural prevalence rates of diabetes and their risk factors at the national level. This study is a part of the national non-communicable diseases (NCD) risk factor surveillance conducted in different geographical locations (North, South, East, West/Central) in India between April 2003 and March 2005. A total of 44,523 individuals (age: 15-64 years) inclusive of 15,239 from urban, 15,760 from peri-urban/slum and 13,524 from rural areas were recruited. Major risk factors were studied using modified WHO STEPS approach. Diabetes was diagnosed based on self-reported diabetes diagnosed by a physician. The lowest prevalence of self-reported diabetes was recorded in rural (3.1%) followed by peri-urban/slum (3.2%) and the highest in urban areas (7.3%, odds ratio (OR) for urban areas: 2.48, 95% confidence interval (CI): 2.21-2.79, p<0.001). Urban residents with abdominal obesity and sedentary activity had the highest prevalence of self-reported diabetes (11.3%) while rural residents without abdominal obesity performing vigorous activity had the lowest prevalence (0.7%). In conclusion, this nation-wide NCD risk factor surveillance study shows that the prevalence of self-reported diabetes is higher in urban, intermediate in peri-urban and lowest in rural areas. Urban residence, abdominal obesity and physical inactivity are the risk factors associated with diabetes in this study. 相似文献

We describe the first patient with an extradural, extramedullary Ewing’s sarcoma tumor mimicking a nerve sheath tumor with no overt evidence of metastasis. A 28-year-old woman with no past medical history presented with a progressive 3-year history of low back pain and right-sided lower extremity radiculopathy after having failed conservative therapies. MRI of the lumbar spine revealed a right-sided enhancing, dumbbell-shaped lesion at the right neural foramen appearing to originate from the L4 nerve root, suspicious for a peripheral nerve sheath tumor or schwannoma. The patient and findings are discussed in the context of the literature, including an update on the relatively recent diagnostic redesignation of the Ewing’s sarcoma family tumors. 相似文献

This study investigates the antihyperlipidemic effect of ursolic acid (UA) on isoproterenol (ISO) induced male albino Wistar rats. Myocardial ischemia was induced by subcutaneous injection of ISO (85 mg/kg BW) twice at an interval of 24 h, for two consecutive days. A significant increase in the activities of the serum marker enzymes [creatine kinase, creatine kinase-MB and lactate dehydrogenease (LDH)], a prominent expression of LDH 1 and LDH 2 isoenzymes, increased levels of plasma total cholesterol (TC), low density lipoprotein-cholesterol, very low density lipoprotein-cholesterol, triglycerides (TG), free fatty acids (FFA), phospholipids (PL) and atherogenic index and decreased level of high density lipoprotein-cholesterol were observed in ISO-induced rats. The levels of TC, TG and FFA increased and the level of PL decreased in the heart tissue of ISO-induced rats. Further, there was an increased DNA damage (Comet assay) and myocardium infarct size as observed by staining with triphenyltetrazolium chloride (TTC). UA was administered subcutaneously for 7 days at a dose of 40 mg/kg BW. UA administration to ischemic rats brought all these parameters to near normality showing the protective effect of UA on ISO-induced rats. 相似文献
