Lower limb muscle moments and power during recovery from forward loss of balance in male and female single and multiple steppers
2011
Abstract Background Studying recovery responses to loss of balance may help to explain why older adults are susceptible to falls. The purpose of the present study was to assess whether male and female older adults, that use a single or multiple step recovery strategy, differ in the proportion of lower limb strength used and power produced during the stepping phase of balance recovery. Methods Eighty-four community-dwelling older adults (47 men, 37 women) participated in the study. Isometric strength of the ankle, knee and hip joint flexors and extensors was assessed using a dynamometer. Loss of balance was induced by releasing participants from a static forward lean (4 trials at each of 3 f…
Reactive stepping behaviour in response to forward loss of balance predicts future falls in community-dwelling older adults.
2013
Background: a fall occurs when an individual experiences a loss of balance from which they are unable to recover. Assessment of balance recovery ability in older adults may therefore help to identify individuals at risk of falls. The purpose of this 12-month prospective study was to assess whether the ability to recover from a forward loss of balance with a single step across a range of lean magnitudes was predictive of falls. Methods: two hundred and one community-dwelling older adults, aged 65–90 years, underwent baseline testing of sensorimotor function and balance recovery ability followed by 12-month prospective falls evaluation. Balance recovery ability was defined by whether particip…
Group fitness activities for the elderly: an innovative approach to reduce falls and injuries
2013
Aim The aim of this study was to examine the opportunity to adopt, for the elderly, already validated function ability tests to better understand how to prevent falls and injuries and to better plan group fitness activities like ballroom dance classes (e.g., Valzer, Polka, Mazurka). Methods A cross-sectional study was conducted. The Berg Balance Scale (BBS) and the Barthel Index (BI) were administered and the occurrence of falls during the previous 2 years was evaluated by anamnesis. One hundred and twenty-two elderly subjects living in Palermo city participated to the study. According to the anamnesis, subjects were divided into two groups: experimental group (EG) and control group (CG). T…
Square-stepping exercise versus strength and balance training for fall risk factors
2008
Background and aims: Feasible and low-cost exercise programmes targeting fall risk factors may decrease the risk of falling in older adults. The purpose of this study was to compare the effects of square-stepping exercise (SSE) training, which is a new and low-cost method designed to improve lower-extremity functional fitness, with strength and balance (SB) training. Methods: The study included 39 community-dwelling adults aged 65 to 74 years. The participants were randomized to either group SSE (n=20) or SB (n=19). They engaged in 70-min group exercise sessions twice a week for 12 weeks. The efficacy of the program was measured with both a 9-item test battery for assessment of physical per…
Fall-related injuries among initially 75- and 80-year old people during a 10-year follow-up.
2007
The aim of this study was to investigate the occurrence, type, scene and seasonal variation of fall related injuries, and the impact of socio-economic factors, mobility limitation, and the most common diseases on the risk of injurious falls over a 10-year follow-up. Elderly residents of Jyvaskyla, Finland, aged initially 75 and 80 years, took part in the study in 1989-1990. The health and functional capacity assessments were carried out at the baseline. Injurious falls were monitored over a 10-year period. The rate of injurious falls per thousand person-years was 188 among women and 78 among men. Of all fall-related diagnoses, head injuries comprised 32%, upper limb injuries 27% and hip inj…
Multidisciplinary management in geriatric day-hospital is beneficial for elderly fallers: A prospective study of 28 cases
2005
We determined whether management including medical, psychological, and physiotherapeutic approaches, over a period of 6 weeks, has a beneficial effect on motor abilities, psychological status, and independence of elderly fallers with psychomotor disadaptation syndrome (PDS). We included 28 subjects (mean age 81.4 years). They were assessed from a medical, motor, and psychological point of view at both the inclusion and the end of the multidisciplinary intervention. A follow-up was conducted with multidisciplinary assessment at 6 and 9 months after the beginning of the study in order to evaluate duration of benefits of the management. The statistical analysis concerned only subjects who took…
Motor speed and lower extremity strength as predictors of fall-related bone fractures in elderly individuals.
2006
Background and aims: The purpose of this prospective population-based study was to examine the combined effects of motor speed and knee extension strength on risk of fall-related bone fractures in elderly individuals over a 10-year period. Methods: Participants were 307 men and women aged 75 or 80 years at baseline, who visited the research laboratory at the University of Jyvaskyla, Finland. Multi-choice motor speed tests and maximal isometric knee extension strength tests were carried out at baseline. Information on fractures was collected from hospital and health center records. The presence of impairment was defined as a score in the lowest tertile of sex- and age-stratified distribution…
Lowered vision as a risk factor for injurious accidents in older people
2008
Poor vision in older people is often related to increased fall risk. However, the association of the severity between visual deficit and risk for all kind of injurious accidents has not been widely studied. The aim of this study was to examine whether visual loss is associated with higher incidence of injurious accidents and whether walking speed or physical activity play a mediating role in the association.416 persons aged 75 and 80 years at baseline underwent visual acuity measurements. Visual acuity (VA)0.3 in the better eye, with spectacle correction when necessary, was defined as visual impairment, VAor=0.3 butor=0.5 as lowered vision, and VA0.5 as normal VA. Hospital records of accide…
Association Between Short Physical Performance Battery and Falls in Older People: The Progetto Veneto Anziani Study.
2014
It is known that weakness in the lower limbs is associated with recurrent falls in old people. Among the tests routinely used to assess lower extremity strength, the Short Physical Performance Battery (SPPB) is one of those used most often, but its relationship with recurrent falls is poorly investigated. We aimed to determine if SPPB scores are related to recurrent falling in a sample of 2710 older-aged people, and to ascertain which test in the SPPB is most strongly associated with a higher rate of falls. In this cross-sectional study, we demonstrated that participants scoring 0-6 in the SPPB were more likely to be recurrent fallers than those scoring 10-12 (odds ratio [OR]=3.46, 95% conf…
Promoting safe walking among older people : the effects of a physical and cognitive training intervention vs. physical training alone on mobility and…
2018
Abstract Background Safe and stable walking is a complex process involving the interaction of neuromuscular, sensory and cognitive functions. As physical and cognitive functions deteriorate with ageing, training of both functions may have more beneficial effects on walking and falls prevention than either alone. This article describes the study design, recruitment strategies and interventions of the PASSWORD study investigating whether a combination of physical and cognitive training (PTCT) has greater effects on walking speed, dual-task cost in walking speed, fall incidence and executive functions compared to physical training (PT) alone among 70–85-year-old community-dwelling sedentary or…
