Quality of life and fall prevention among the aged Improvement of quality of life is considered to be one of the most important goals of prevention, treatment and rehabilitation among the aged. The study aimed to describe and assess fall prevention interventions as a quality of life indicator, and to describe the social dimension of health-related quality of life among the aged. In addition, it aimed to assess the effects of fall prevention intervention on quality of life among the aged. The study was implemented by using a methodological triangulation. The data in the systematic review was retrieved from the databasis of medical and nursing sciences. Home-dwelling aged (n=19) participated in the qualitative study of a social dimension of quality of life. The data was gathered by the thematic interview method. The quantitative multifactorial fall prevention study comprised 591 participants, either the aged living at home or in sheltered housing, showing an increased risk of falling. Participants were randomized into an intervention or a control group. Follow-up measurements were carried out after a 12 month intervention. The data was collected by the 15D quality of life instrument and a structured questionnaire. Based on the systematic review, only in a few studies fall prevention produced positive effects on dimensions of quality of life (physical function, social function, vitality, mental health, environmental domain). Based on the thematic interview the social dimension of quality of life consisted of three themes: personal values, personal milieu and personal daily life. Based on the fall prevention program, depressive symptoms and distress decreased, managing in usual activities improved, sexual activity and phone contacts increased among men. In women, managing in usual activities improved, socializing increased and discomfort and symptoms decreased. Within the groups, self-perceived health improved among women in the intervention group and among men in the control groups. In addition, fear of falling and feelings of insecurity reduced among women in the intervention group. Personal daily life with its activities opened up new perspectives into the social dimension of good quality of life, which was emphasized especially in the interviews of the oldest participants. Multifactorial fall prevention can affect positively some physical and psychosocial dimensions of quality of life among the community-dwelling aged. Additional studies with larger sample sizes, longer follow-up periods and multiple outcome measures are needed. Fall prevention intervention may affect quality of life by different mechanisms, and the quantitative and qualitative assessment of its effects should also be included in the interventions of randomized controlled trials.

Variáveis relacionadas ao processo de adesão a um programa de prevenção de quedas em idosos cadastrados na Estratégia de Saúde da Família

Introduction: Falls among older adults is a public health problem, therefore it is necessary preventive actions, however the adherence is the major problem faced by practitioners and researchers working on falls prevention programs. Objective: To evaluate the variables related to the adherence to falls prevention programs among the elderly enrolled in a Basic Health Unit (BHU). Methods: Was performed an observational cross-sectional analytical study. All elderly registered in a BHU and able to ambulate independently were invited to participate in a falls prevent program. The Elderly who Adhered to the Program (EAP) were evaluated at BHU; and the Elderly Not Adhered to the Program (ENAP) were identified and assessed at home. The assessment for both groups was performed using an evaluation form containing personal data, measures and clinical scales to assess cognitive status, balance, mobility, fear of falling, handgrip strength. Data were analyzed with SPSS 20.0. In addition to this assessment, the ENAP underwent a semi structured interview, in which we used the qualitative approach based on the figure of the Collective Subject Discourse. Results: The study included 222 elderly, 111 EAP and 111ENAP, most aged between 70 and 79 years (48.2%), female (68.5%), married (52.3%) and illiterate (47.7%). Consolidated as protective factors for adherence, worst rates of physical activity (p = 0.001), balance (p = 0.010) and cognition (p = 0.007). The interview of ENAP identified two themes: "Local implementation of programs for the prevention of falls" and "Relationship between BHU and the elderly health care," and found that the elderly who did not adhere were unable to displace and did not mention that primary care programs are related to health care in elderly. Conclusions: Elderly who do not adhere to the program differ from elderly who adhere as worst indices of cognition, balance and physical activity which implies greater risk of falling; and they were unable to participate in falls prevention program and by to be caregiver and showed displacement difficult

Rehabilitation Engineering in Parkinson's disease

Impairment of postural control is a common consequence of Parkinson's disease (PD) that becomes more and more critical with the progression of the disease, in spite of the available medications. Postural instability is one of the most disabling features of PD and induces difficulties with postural transitions, initiation of movements, gait disorders, inability to live independently at home, and is the major cause of falls. Falls are frequent (with over 38% falling each year) and may induce adverse consequences like soft tissue injuries, hip fractures, and immobility due to fear of falling. As the disease progresses, both postural instability and fear of falling worsen, which leads patients with PD to become increasingly immobilized. The main aims of this dissertation are to: 1) detect and assess, in a quantitative way, impairments of postural control in PD subjects, investigate the central mechanisms that control such motor performance, and how these mechanism are affected by levodopa; 2) develop and validate a protocol, using wearable inertial sensors, to measure postural sway and postural transitions prior to step initiation; 3) find quantitative measures sensitive to impairments of postural control in early stages of PD and quantitative biomarkers of disease progression; and 4) test the feasibility and effects of a recently-developed audio-biofeedback system in maintaining balance in subjects with PD. In the first set of studies, we showed how PD reduces functional limits of stability as well as the magnitude and velocity of postural preparation during voluntary, forward and backward leaning while standing. Levodopa improves the limits of stability but not the postural strategies used to achieve the leaning. Further, we found a strong relationship between backward voluntary limits of stability and size of automatic postural response to backward perturbations in control subjects and in PD subjects ON medication. Such relation might suggest that the central nervous system presets postural response parameters based on perceived maximum limits and this presetting is absent in PD patients OFF medication but restored with levodopa replacement. Furthermore, we investigated how the size of preparatory postural adjustments (APAs) prior to step initiation depend on initial stance width. We found that patients with PD did not scale up the size of their APA with stance width as much as control subjects so they had much more difficulty initiating a step from a wide stance than from a narrow stance. This results supports the hypothesis that subjects with PD maintain a narrow stance as a compensation for their inability to sufficiently increase the size of their lateral APA to allow speedy step initiation in wide stance. In the second set of studies, we demonstrated that it is possible to use wearable accelerometers to quantify postural performance during quiet stance and step initiation balance tasks in healthy subjects. We used a model to predict center of pressure displacements associated with accelerations at the upper and lower back and thigh. This approach allows the measurement of balance control without the use of a force platform outside the laboratory environment. We used wearable accelerometers on a population of early, untreated PD patients, and found that postural control in stance and postural preparation prior to a step are impaired early in the disease when the typical balance and gait intiation symptoms are not yet clearly manifested. These novel results suggest that technological measures of postural control can be more sensitive than clinical measures. Furthermore, we assessed spontaneous sway and step initiation longitudinally across 1 year in patients with early, untreated PD. We found that changes in trunk sway, and especially movement smoothness, measured as Jerk, could be used as an objective measure of PD and its progression. In the third set of studies, we studied the feasibility of adapting an existing audio-biofeedback device to improve balance control in patients with PD. Preliminary results showed that PD subjects found the system easy-to-use and helpful, and they were able to correctly follow the audio information when available. Audiobiofeedback improved the properties of trunk sway during quiet stance. Our results have many implications for i) the understanding the central mechanisms that control postural motor performance, and how these mechanisms are affected by levodopa; ii) the design of innovative protocols for measuring and remote monitoring of motor performance in the elderly or subjects with PD; and iii) the development of technologies for improving balance, mobility, and consequently quality of life in patients with balance disorders, such as PD patients with augmented biofeedback paradigms.

Quedas em idosos assistidos na estratégia saúde da família: frequência e fatores associados

The growth of the elderly population is a global phenomenon and, in Brazil, this transformation is happening in a very rapid rhythm. With the current population aging, this emerging age group will need more health care and attention. One of the characteristics of the population aging is the progressive accumulation of disabilities, which makes it more vulnerable to falls. This study was developed with the purpose of knowing the episode falls in the scope of an elderly population treated at a Family Health Unit. It is a research with cross-sectional nature, and its sample was composed by 121 elderly. The research was approved by the Ethics Committee of HUOL, with Opinion nº 816.022. We applied a questionnaire to the participants, and the results were statistically analyzed by using Chi-square test and Fisher’s exact test to verify the association between variables. In order to perform a multivariate analysis, we used the method of the Binomial Logistic Regression. For both tests, we accepted significance p<0,05 and CI of 95%. The results prove that the majority belongs to the female gender (76,9%); the age group of elderly reaches 88,4% and 11,6% is over-aged; regarding the marital status, 35,3% are married and 29,4% widowed; 92,1% with family income between one and two minimum wages; and 91,8% live with their partners and/or children. Regarding the frequency of falls, we found that 61,2% of the surveyed elderly suffered one or more falls in 2014. As associated factors, it became clear that 73,8% were due to extrinsic factors, 6,4% to intrinsic factors and 21,4% to both factors. As a consequence of the fall, we found that 89,2% have fear of falling again, 37,3% showed anxiety and 13,3% had their ambulation affected. Concerning the exposure to the risk factors, the most prevalent places were: street/avenue (31,0%), pavement (19,0%), living room (14,3%) and courtyard/backyard (10,7%). The study has proven a statistically significant association among female gender (p=0,001), rubble/objects in the backyard (p=0,015) and furniture that may cause accidents (p=0,005). It was evident among the elderly people surveyed, 72.7% receive little information about falls, being a risk factor for falls. We conclude that there is a high frequency of falls in the surveyed elderly, thereby constituting a worrisome data because this event in the elderly population is a serious matter, which raises the need to ensure them a safe environment in their homes and, above all, outside them. The information provided by the Family Health Strategy team are important to avoid these occurrences, which reinforces the need for developing health education activities together with the population as a way to prevent and reduce the occurrence of falls, thereby improving the quality of life of elderly.

Why fear snakes and spiders? Evidence for a learning-based account of fear-relevant stimulus-processing

Fear-relevant stimuli, such as snakes, spiders and heights, preferentially capture attention as compared to nonfear-relevant stimuli. This is said to reflect an encapsulated mechanism whereby attention is captured by the simple perceptual features of stimuli that have evolutionary significance. Research, using pictures of snakes and spiders, has found some support for this account; however, participants may have had prior fear of snakes and spiders that influenced results. The current research compared responses of snake and spider experts who had little fear of snakes and spiders, and control participants across a series of affective priming and visual search tasks. Experts discriminated between dangerous and nondangerous snakes and spiders, and expert responses to pictures of nondangerous snakes and spiders differed from those of control participants. The current results dispute that stimulus fear relevance is based purely on perceptual features, and provides support for the role of learning and experience.

The dark side of the Mediterranean : expression of fear from the inquisition to the present

Inside the stones of its most famous buildings, Évora keeps mysteries and secrets which constitute the most hidden side of its cultural identity. A World Heritage site, this town seems to preserve, in its medieval walls, a precious knowledge of the most universal and ancient human emotion: fear. Trying to transcend many of its past and future fears, some of its historical monuments in Gothic style were erected against the fear of death, the most terrible of all fears, which the famous inscription, in the Bones Chapel of the Church of São Francisco, insistently reminds us, through the most disturbing words: “Nós ossos que aqui estamos pelos vossos esperamos”. If the first inquisitors worked in central Europe (Germany, northern Italy, eastern France), later the centres of the Inquisition were established in the Mediterranean regions, especially southern France, Italy, Portugal, and Spain. Consequently, the roots of fear in Évora are common to other towns, where the Inquisition developed a culture of fear, through which we can penetrate into the dark side of the Mediterranean, where people were subjected to the same terrifying methods of persecution and torture. This common geographical and historical context was not ignored by one of the most famous masters of American gothic fiction, Edgar Allan Poe. Through the pages of The Pit and the Pendulum, readers get precise images of the fearful instruments of terror that were able to produce the legend that has made the first grand inquisitor, Tomas de Torquemada, a symbol of ultimate cruelty, bigotry, intolerance, and religious fanaticism, which unfortunately are still the source of our present fears in a time when religious beliefs can be used again as a motif of war and destruction. As Krishnamurti once suggested, only a fundamental realization of the root of all fear can free our minds.

Chronicity Factors Of Temporomandibular Disorders: A Critical Review Of The Literature.

Facial pain often persists long after any identifiable organic pathology has healed. Moreover, in a subgroup of patients with temporomandibular disorder (TMD), no treatment is effective. Knowledge of factors associated with persistent pain in TMD could help identify personalized treatment approaches. Therefore, we conducted a critical review of the literature for the period from January 2000 to December 2013 to identify factors related to TMD development and persistence. The literature findings showed that chronic TMD is marked by psychological distress (somatization and depression, affective distress, fear of pain, fear of movement, and catastrophizing) and characteristics of pain amplification (hyperalgesia and allodynia). Furthermore, these factors seem to interact in TMD development. In addition, our review demonstrates that upregulation of the serotonergic pathway, sleep problems, and gene polymorphisms influence the chronicity of TMD. We conclude that psychological distress and pain amplification contribute to chronic TMD development, and that interactions among these factors complicate pain management. These findings emphasize the importance of multidisciplinary assistance in TMD treatment.
