The present study attempted deriving and solving the falling- cylinder governing equations for power law model non-Newtonian fluids. Based on this theoretical study, a novel falling- cylinder rheometer (FCR) was designed and constructed to measure the Theological properties of non-Newtonian fluids. Different falling cylinders with predesigned densities were used to determine the apparent viscos...

BACKGROUND Fear of falling is common among persons with Parkinson's disease and is negatively associated with quality of life. However a lack of in-depth understanding of fear of falling as a phenomenon persists. This qualitative study aimed to explore the experiences of fear of falling in persons with Parkinson's disease. METHODS Individual interviews were performed with twelve persons with ...

The matter of falling plays an important role in the quality of older peoples’ life for which lots of tools that single vulnerable elders out. This study is to recognize and introduce these tools. Using key words regarding older people falling on Google Scholar, Wiley Blackwell, Pub Med databases, an expansive search on the articles of the year has been done, based on which this study is recogn...

OBJECTIVE To ascertain if there is a correlation between low back pain (LBP), fear of falling, and disability so that the patients with LBP are aware of the fact that other problems may occur with LBP. Hence, steps can be taken for decreasing the fear of falling and disability in order to improve the condition of patients. METHODS A sample size of 100 patients with low back pain, with a range...

Most of the research related to the topic of falling strategies considers falling to be an unavoidable part of bipedal walking and is focused on developing strategies to avoid falls and to minimize mechanical damage. We take an alternative point of view and regard falling as a means to an end. We present our falling strategy for the specific case of a robot soccer goalie that deliberately jumps...

PURPOSE To identify the most common beliefs concerning the negative consequences of falling and determine whether these motivate avoidance of activity. DESIGN AND METHODS A questionnaire assessing feared consequences of falling was completed by 224 community-living people aged older than 75. Beliefs about the consequences of falling were related to demographic characteristics, falling history...

background: falling has a great importance among the elderlies. even if no physical injury occurs, it can cause fear of fallingdown again and, consequently, reduce older adults’ activities. with regard to the prevalence of falling among older adults, its prevention is essential. therefore, the present study was aimed to define the effect of need-based education on prevention of older adults’ fa...

BACKGROUND Fear of falling and avoidance of activity are common in old age and are suggested to be (public) health problems of equal importance to falls. Earlier studies of correlates of fear of falling and avoidance of activity did hardly differentiate between severe and mild levels of fear of falling and avoidance of activity which may be relevant from clinical point of view. Furthermore, mos...

With a sample survey (N = 266) of elderly adults residing in six housing developments in Massachusetts, we used logistic regression to: (a) identify covariates of fear of falling among all subjects and (b) identify covariates of activity curtailment among the subset of subjects who were afraid of falling. Fifty-five percent of respondents were afraid of falling; of those who were afraid, 56% ha...
