BACKGROUND: Perturbation training is an emerging paradigm to reduce idiopathic falls (without clinical signs or symptoms) in older adults. While a higher threat dosage (intensity) in motor learning often directly relates to greater adaptation, retention, and generalization, little is known whether increasing the practice dosage (repetition) of slip-perturbation training would necessarily improve its outcomes. RESEARCH QUESTION: Can higher practice dosage of treadmill slip-perturbation training lead to greater generalization to an overground slip immediately after the training? METHODS: Forty-five community-dwelling older adults (73...

Numerous studies have reported the benefits of physical exercise in older adults. However, studies performed in long-term nursing home (LTNH) residents are scarce. A literature search was conducted to identify physical exercise intervention studies that were randomized and controlled and that assessed gait ability in older LTNH residents using both walking speed and timed up-and-go (TUG) tests simultaneously. Together, these tests have been defined under the term "gait ability"; they are widely used to screen for impaired physical function, and can predict accelerated functional decline, difficulty with activities of daily living (ADL), falls, and disability in older adults...

The aim of this study was to investigate if a machine learning algorithm utilizing triaxial accelerometer, gyroscope, and magnetometer data from an inertial motion unit (IMU) could detect surface- and age-related differences in walking. Seventeen older (71.5 ± 4.2 years) and eighteen young (27.0 ± 4.7 years) healthy adults walked over flat and uneven brick surfaces wearing an inertial measurement unit (IMU) over the L5 vertebra. IMU data were binned into smaller data segments using 4-s sliding windows with 1-s step lengths...

BACKGROUND: Gait impairment places older adults and people with Parkinson's disease (PD) at an increased risk of falls when walking over obstacles. Increasing the height of obstacles results in greater challenge to balance however little is known about the demands encountered when negotiating obstacles of greater depth which may be greater for PD who often walk with a short, shuffling gait. RESEARCH QUESTION: To describe gait adaptation in older adults and people with PD when walking over long and tall obstacles...

BACKGROUND: Effects of exercise on foot clearances are important. In older adults variations in foot clearances during walking may lead to a fall, but there is a lack of information concerning stair negotiation in older adults. Whether a condition of post exercise changes foot clearances between steps of a staircase in older adults still unknown. OBJECTIVE: To determine differences in clearances when older adults negotiate different steps of a staircase before and after a session of aerobic exercise...

BACKGROUND: Tools to detect subtle balance deficits in high-functioning community-dwelling older adults are lacking. The Community Balance and Mobility Scale (CBM) is a valuable tool to measure balance deficits in this group; however, it is not yet available in the German language. OBJECTIVE: The aim was 1) to translate and cross-culturally adapt the CBM into the German language and 2) to investigate the measurement properties of the German CBM (G-CBM). MATERIAL AND METHODS: The original CBM was translated into the German language according to established guidelines...

Older adults with falls risk tend to look away prematurely from targets for safe foot placement to view future hazards; behaviour associated with increased anxiety and stepping inaccuracies. We aimed to determine the effectiveness of route previewing in reducing anxiety and optimizing gaze behaviour and stepping performance of younger and older adults. Nine younger and nine older adults completed six walks with three task complexities over two sessions. Each trial used either an isolated stepping target, or a target followed by either one or two obstacles...

Background: Turning is a challenging mobility task requiring proper planning, coordination, and postural stability to be executed efficiently. Turn deficits can impair mobility and lead to falls in patients with neurodegenerative disease, such as Parkinson's disease (PD). It was previously shown that the cranio-caudal sequence involved during a turn (i.e., motion is initiated by the head, followed by the trunk) exhibits a signature that can be captured using an inertial system and analyzed through the Kinematics Theory...

INTRODUCTION: This study examined the associations of BMI category and central obesity status, with falls among community-dwelling older adults in the U.S. METHODS: Data were drawn from the 2012 and 2014 U.S. Health and Retirement Study, a nationally representative longitudinal panel study funded by the National Institute of Aging. The study participants were U.S. community-dwelling older adults aged ≥65 years (N=3,383). Multiple logistic regression and Poisson regression analyses examined the associations of BMI category and central obesity (waist circumference >102 cm in men and >88 cm in women) with experiencing a fall and fall injury, after adjusting for all other covariates...

Gait impairment is a core feature of Parkinson's disease (PD) with implications for falls risk. Visual cues improve gait in PD but the underlying mechanisms are unclear. Evidence suggests that attention and vision play an important role however the relative contribution from each is unclear. Measurement of visual exploration (specifically saccade frequency) during gait allows for real-time measurement of attention and vision. Understanding how visual cues influence visual exploration may allow inferences of the underlying mechanisms to response which could help to develop effective therapeutics...

This study aimed at identifying the effects of self-paced cycling on the cognitive and functional status and fall risk on institutionalized older adults without cognitive impairment. Thirty-nine individuals were randomly assigned to an exercise (EG) or to a control (CG) group. The EG participants cycled at their self-selected intensity at least for 15 minutes daily during 15 months. The CG participants performed recreational activities. The Mini-Mental State Examination, Fuld Object Memory Evaluation, and Symbol Digit Modality Test were used for cognitive assessments...

Reduced foot clearance when walking may increase the risk of trips and falls in people with Parkinson's disease (PD). Changes in foot clearance in people with PD are likely to be associated with temporal-spatial characteristics of gait such as walking slowly which evokes alterations in the temporal-spatial control of stepping patterns. Enhancing our understanding of the temporal-spatial determinants of foot clearance may inform the design of falls prevention therapies. Thirty-six people with PD and 38 age-matched controls completed four intermittent walks under two conditions: self-selected and fast gait velocity...

Context • Dancing has been used as a form of exercise to improve functional and metabolic outcomes during aging. The field lacks randomized, clinical trials (RCTs) evaluating metabolic outcomes related to dance interventions, but dancing may be a form of exercise that could induce positive effects on the metabolic health of older adults. However, primary studies seem very heterogonous regarding the trial designs, characteristics of the interventions, the methods for outcomes assessments, statistical powers, and methodological quality...

The endocochlear potential (EP) provides part of the electrochemical drive for sound-driven currents through cochlear hair cells. Intense noise exposure (110 dB SPL, 2 h) differentially affects the EP in three inbred mouse strains (C57BL/6 [B6], CBA/J [CBA], BALB/cJ [BALB]) (Ohlemiller and Gagnon, 2007, Hearing Research 224:34-50; Ohlemiller et al., 2011, JARO 12:45-58). At least for mice older than 3 mos, B6 mice are unaffected, CBA mice show temporary EP reduction, and BALB mice may show temporary or permanent EP reduction...

BACKGROUND: Globally, populations are aging with increasing life spans. The normal aging process and the resulting disabilities increase fall risks. Falls are an important cause of injury, loss of independence and institutionalization. Technologies have been developed to detect falls and reduce their consequences but their use and impact on quality of life remain debatable. Reviews on fall detection technologies exist but are not extensive. A comprehensive literature review on the state of knowledge of fall detection technologies can inform research, practice, and user adoption...

BACKGROUND: Fear of falling (FOF) is associated with restricted activities, increased risk of falling, and decreased quality of life. A Matter of Balance (AMOB) is an evidence-based programme designed to decrease FOF. The current study investigated the influence of the AMOB on activity avoidance caused by FOF in older adults using the Fear of Falling Avoidance Behavior Questionnaire (FFABQ), health-related quality of life, and a question regarding concerns about falling. METHODS: Participants of this quasi-experimental, one-group, pretest-post-test study design were older adults from community sites in the Phoenix, Arizona, metropolitan area...

Synthetic cannabinoids are psychoactive substances designed to mimic the euphorigenic effects of the natural cannabis. Novel unregulated compounds appear once older compounds become illegal. It has been previously reported that synthetic cannabinoids are different than Δ9 -tetrahydrocannabinol (Δ9 -THC) as they have chemical structures unrelated to Δ9 -THC, different metabolism and, often, greater toxicity. This study aimed to investigate the effects of three novel synthetic cannabinoids and pure Δ9 -THC on body temperature, nociceptive threshold, anxiety, memory function, locomotor and exploratory parameters, and depression...
