Introduction: To evaluate fall-prevention rehabilitative slippers for use by self-caring, independent older adults. Materials and Methods: This assessor-blinded, randomized, and controlled 1-year study included 59 self-caring, independent participants (49 women) who attended day services. The mean age of participants was 84.0 ± 5.3 years. Participants were randomly selected from 8 nursing homes. We tested slippers top-weighted with a lead bead (200, 300, or 400 g). Intervention group participants walked while wearing the slippers for 10-20 min, 1-3 days/week at the day service center. Fall risk was measured using the Berg Balance Scale and the Tinetti Performance-Oriented Mobility Assessment (POMA) before and at 3-month intervals after the intervention/control phase. Results: After 12 months, the intervention group demonstrated significant improvement. Berg Balance and POMA compared to the control group ( p < .05 p < .01, respectively). Mobility scores improved significantly for both measurements in the intervention group before and after ( p < .01), but the control group had significantly lower scores. Discussion: Overall, falls decreased in the intervention group from 10 to 7, and control group falls increased from 9 to 16 ( p = .02). No adverse events related to the intervention were reported. Conclusions: Rehabilitation training slippers may reduce falls in older adults.

Abstract It is important to evaluate leaching behavior in agricultural soils to prevent the pollution of groundwater by pesticides. We identified the distribution coefficients (Kd) of ten pesticides with different physicochemical properties and compared their leaching characteristics using wick lysimeters from three distinct soil types on Jeju Island. The Kd values varied by pesticide and soil, but were within the range of 1.2 to 4231 L kg−1. Based on the European standard (Kd < 10 L kg−1), six pesticides (alachlor, ethoprophos, carbofuran, napropamide, tebuconazole, and etridiazole) were mobile in at least one tested soil, and their soil organic carbon affinity was ≤ 5.811. This value differed greatly from the other pesticides (16.533 and higher). The solubility of the six mobile pesticides was ≥ 32 mg L−1, which substantially differed from the other pesticides (≤ 0.71 mg L−1). Thus, we conclude that our mobility assessment, which is based on Kd values, can be used to predict the leaching of pesticides in the volcanic ash soils of Jeju Island. The use of pesticides should be strictly controlled to reduce the possibility of groundwater contamination.

<b><i>Introduction:</i></b> Falls among older people are a major health issue and the first cause of accidental death after 75 years of age. Post-fall syndrome (PFS) is commonly known and yet poorly studied. <b><i>Objective:</i></b> Identify risk factors for PFS and do a follow-up 1 year later. <b><i>Methods:</i></b> We included all patients over 70 years of age hospitalized after suffering a fall in a case-control study, and then followed them in a cohort study. PFS was retained in case of functional mobility decline (transferring, walking) occurring following a fall in the absence of an acute neurological, orthopedic or rheumatic pathology directly responsible for the decline. The data initially collected were: clinical (anamnestic, emergency and departmental/ward evolution, medical history, lifestyle, treatments, clinical examination items); and imaging if the patient had been subjected to brain imaging in the last 3 years prior to inclusion. Regarding the follow-up at 1 year, we collected from the general physician the occurrence and the characteristics of new falls, functional mobility assessment, hospitalization and death. <b><i>Results:</i></b> Inclusion took place from March 29, 2016 to June 7, 2016 and follow-up until June 30, 2017. We included 70 patients. A total of 29 patients exhibited a PFS (41.4 %). Risk factors for PFS included age, walking disorder prior to the fall, the use of a walking aid prior to the fall, no unaccompanied outdoor walk in the week before the fall, visual impairment making close reading impossible, stiffness in ankle dorsiflexion, grip strength and the fear of falling. Among patients with PFS, 52.9% could still perform a transfer at 1 year and 64.7% could still walk against 80.7% and 85.2%, respectively, for patients without PFS. <b><i>Conclusion:</i></b> The study showed the existence of body functions/structure impairments and activity limitations prior to the fall among patients exhibiting a PFS. This suggests the existence of a pre-fall syndrome, i.e., a psychomotor disadaptation syndrome existing prior to the fall. Among the 8 risk factors, fear of falling, vision impairment and muscle strength could be targeted for improvement. The diagnosis of PFS could be a marker of loss of functional mobility at 1 year.

The objective of this study was to develop and deploy a novel motion capture system that utilizes off-the-shelf, dive-rated hardware to measure 3-D whole body reach envelopes of space suits in an underwater analog, which simulates a microgravity environment. The accuracy of the developed system was compared to a gold standard motion capture system in a dry-land condition before deployment. This study is ultimately aimed at providing a methodology for quantitative metrics to evaluate and compare the mobility performances of a newly developed prototype space suit versus an existing space suit at the Neutral Buoyancy Laboratory (NBL) at NASA’s Johnson Space Center.

ABSTRACT Introduction Return-to-duty (RTD) readiness assessment for service members (SM) following concussion requires complex clinical considerations. The Portable Warrior Test of Tactical Agility (POWAR-TOTAL) is a functional assessment which improves on previous laboratory-based RTD assessments. Methods Sixty-four SM diagnosed with concussion and 60 healthy control (HC) SM participated in this study. Group differences were analyzed to validate the POWAR-TOTAL. The High-level Mobility Assessment Test (HiMAT) was used to examine concurrent construct validity. An exploratory logistic regression analysis examined predictive validity. Results The groups were demographically well-matched except for educational level. POWAR-TOTAL measures were statistically significantly different between the groups with moderate to large effect sizes. Concussed participants were less likely to be able to complete all trials of the POWAR-TOTAL. Motor scores correlated highly with HiMAT scores. POWAR-TOTAL motor task performance and membership in the control group was significantly associated with self-reported physical readiness to deploy. Conclusion The POWAR-TOTAL is a clinically feasible, military relevant assessment that is sensitive to differences between concussed and HC SM. This analysis supports the discriminant and construct validity of the POWAR-TOTAL, and may be useful for medical providers evaluating RTD readiness for SM who have sustained a concussion.

OBJETIVO: O presente estudo teve como objetivo avaliar o equilíbrio dinâmico de idosas institucionalizadas pré e pós-intervenção com hidrocinesioterapia. MÉTODO: Para avaliação do equilíbrio foram utilizados dois testes: Escala de Equilíbrio de Berg (EEB) e Performance Oriented Mobility Assessment (POMA). As atividades aquáticas foram realizadas em piscina rasa, uma vez por semana, num total de 15 sessões. Foi aplicado o teste t Student para comparar as avaliações pré e pós-intervenção. RESULTADOS: Observou-se melhora na manutenção do equilíbrio corporal no período após a hidrocinesioterapia de forma estatisticamente significativa nas avaliações dos dois testes propostos (EEB p < 0,01 e POMA p < 0,05). CONCLUSÕES: O programa de hidrocinesioterapia demonstrou ser efetivo para a melhora do equilíbrio dinâmico e diminuição do risco de quedas de idosas institucionalizadas. Sendo assim, é um recurso fisioterapêutico que pode ser recomendado para prevenir quedas desta população.
