Multifocal glasses increase variability of toe clearance in older adults navigating stairs and increase fall risk; however, little is known about the biomechanics of stair navigation in individuals with multifocal IOLs. This study compared clearance while ascending and descending stairs in individuals with monofocal versus multifocal IOLs. Eight participants with multifocal IOLs (4 men, 4 women; mean age = 66.5 yr, standard deviation [SD] = 6.26) and fifteen male participants with monofocal IOLs (mean age = 69.9 yr, SD = 6.9) underwent vision and mobility testing. Motion analysis recorded kinematic and custom software-calculated clearances in three-dimensional space. No significant differences were found between groups on minimum clearance or variability. Clearance differed for ascending versus descending stairs: the first step onto the stair had the greatest toe clearance during ascent, whereas the final step to the floor had the greatest heel clearance during descent. This preliminary study indicates that multifocal IOLs have similar biomechanic characteristics to monofocal IOLs. Given that step characteristics are related to fall risk, we can tentatively speculate that multifocal IOLs may carry no additional fall risk.</p>","PeriodicalId":50065,"journal":{"name":"Journal of Rehabilitation Research and Development","volume":"53 6","pages":"933-944"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1682/JRRD.2015.02.0030","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34971395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Medication-free trauma-exposed participants were either healthy (n = 7) or experiencing comorbid chronic pain/posttraumatic stress disorder (PTSD) (n = 5). Peak oxygen consumption (VO2) during exercise testing was used to characterize cardiorespiratory fitness. Peak VO2 correlated with baseline and peak NPY levels (r = 0.66, p < 0.05 and r = 0.69, p < 0.05, respectively), as well as exercise-induced changes in ALLO (r = 0.89, p < 0.001) and peak ALLO levels (r = 0.71, p < 0.01). NPY levels at the peak of exercise correlated with pain threshold 30 min after exercise (r = 0.65, p < 0.05), while exercise-induced increases in ALLO correlated with pain tolerance 30 min after exercise (r = 0.64, p < 0.05). In contrast, exercise-induced changes in cortisol and DHEA levels were inversely correlated with pain tolerance after exercise (r = -0.69, p < 0.05 and r = -0.58, p < 0.05, respectively). These data suggest that cardiorespiratory fitness is associated with higher plasma NPY levels and increased ALLO responses to exercise, which in turn relate to pain sensitivity. Future work will examine whether progressive exercise training increases cardiorespiratory fitness in association with increases in NPY and ALLO and reductions in pain sensitivity in chronic pain patients with PTSD.","PeriodicalId":50065,"journal":{"name":"Journal of Rehabilitation Research and Development","volume":"53 1 1","pages":"95-106"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1682/JRRD.2014.10.0267","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67551377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the seven years that I have been a Scientific Program Manager in the Rehabilitation Research and Development Service in the Office of Research and Development (ORD), I have witnessed an increase in the number of projects and funded investigators within VA's pain portfolio. In 2009, there were approximately 57 projects on pain research. In July 2015, the number of projects was 109, and importantly, the investment in pain research almost tripled within this time span. This change can be attributed to the increased interest in pain research within VA's scientific and clinical communities brought about by the unique chronic pain management needs of Veterans returning from Iraq and Afghanistan and the collaborative effort between VA's pain research community and ORD to spotlight pain research. Pain research in ORD appropriately spans the translational research spectrum and includes basic/foundational research mainly in animal models, epidemiology to determine the distribution of various painful conditions in the VA, pain diagnosis, management and treatment of pain, underlying causes of chronic pain including the transition from the acute to chronic state, adverse events associated with pain management, and health services-level research. This editorial covers a fraction of the innovative and unique areas of pain research being conducted at the VA and the important role VA researchers play in the pain community, as evidenced by VA participation in the Interagency Pain Research Coordinating Committee (IPRCC) National Pain Strategy (NPS). * Pain management: The challenge of treating Veterans with chronic pain and coexisting conditions has sparked an interest in how to care for these individuals effectively. Team-based integrative approaches play up to VA's strengths as a healthcare system and include the clinicians who see Veterans in the clinic, who also conduct basic up to health services research. This is reflected in the high number of treatment-related projects (n = 46) examining the effectiveness of exercise and activity; complementary approaches, including electroceuticals (e.g., transcranial magnetic stimulation) and yoga; and testing different formulations of drug therapies focused not only on pain but also on coexisting conditions, including posttraumatic stress disorder (PTSD), depression, sleep, and substance use disorders. The emphasis of treatment includes reduced dependence on opioids as \"go to\" drugs and examining alternate forms of pain management, putting the Veteran in the driver's seat in managing the painful condition. * Comparative-effectiveness research: Comparative-effectiveness studies emphasize the importance of \"evidence-based practice\" and \"practice-based evidence\" results and are reality checks as to what treatments should be effective and what treatments actually are effective.

To address this knowledge gap, we conducted interviews of 15 inpatients, 8 receiving palliative care, and 15 outpatients receiving CIH in the VA. Pain was the precipitating factor in all participants' experience. Participants were asked about their experience in the VA and their opinions about which therapies would most benefit other Veterans. Participants reported that massage was well-received and resulted in decreased pain, increased mobility, and decreased opioid use. Major challenges were the high ratio of patients to CIH providers, the difficulty in receiving CIH from fee-based CIH providers outside of the VA, cost issues, and the role of administrative decisions in the uneven deployment of CIH across the VA. If the VA is to meet its goal of offering personalized, proactive, patient-centered care nationwide then it must receive support from Congress while considering Veterans' goals and concerns to ensure that the expanded provision of CIH improves outcomes. </p>","PeriodicalId":50065,"journal":{"name":"Journal of Rehabilitation Research and Development","volume":"53 1 1","pages":"117-26"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1682/JRRD.2015.01.0015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67552089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bland-Altman plots demonstrated good agreement between two repeated measurements. Significant differences between patients with stroke and nondisabled controls were found in 9 of 14 iTUG parameters analyzed.
