Effects of Enriched Physical Activity Environments on Balance and Fall Prevention in Older Adults: A Scoping Review.
Authors: Shafizadeh M, Manson J, Fowler-Davis S, Ali K, Lowe AC, Stevenson J, Parvinpour S, Davids K Abstract The incidence of falling, due to aging, is related to both personal and environmental factors. There is a clear need to understand the nature of the major risk factors and design features of a safe and navigable living environment for potential fallers. The aim of this scoping review was to identify studies that have examined the effectiveness of environments, which promote physical activity and have an impact on falls prevention. Selected studies were identified and categorized into four main topics: built...

Effect of Dance on Postural Control in People with Parkinson's Disease: A Meta-Analysis Review.
Authors: de Almeida HS, Porto F, Porretti M, Lopes G, Fiorot D, Bunn PDS, da Silva EB Abstract This systematic review verified the effect of dance on postural control in people with Parkinson's disease (PD) and investigated whether this practice can be as effective over a short period as when it is performed over a longer period in relation to the postural control of this population. The search was performed in April 2019 in nine databases. Only randomized/quasi-randomized controlled trials with participants with idiopathic PD were included. The meta-analysis of the 11 articles included, with 13 results, showed tha...

Potential Motor Benefits of Visual Feedback of Error Reduction for Older Adults.
This study investigated how visual feedback of virtual error reduction (ER) modified the visuomotor performance of older adults with limited attentional capacity. Error structures of young and older adults during birhythmic force tracking were contrasted when the visualized error size was exact or half of the actual size. As compared with full-size error feedback, ER feedback improved the force tracking symmetry of older adults, but undermined that of young adults. Extended Poincaré analysis revealed that young adults presented greater short-term error variability (mean value of κ-lagged SD1 of the error signa...

The participants included 18 patients with knee osteoarthritis undergoing TKA. The gait at a comfortable velocity was assessed pre- and post-TKA by a triaxial accelerometer attached to the neck and lumbar regions. Measurement post-TKA was performed 4 weeks after surgery. Trunk fluctuation was estimated by the root mean square (RMS) of acceleration and RMS ratio (the ratio of RMS in each direction to the total RMS). Regularity of gait was estimated usin...

Postexercise Hypotension After Muscle Power Training Session in Older Adults With Hypertension.
Authors: Machado Filho J, Machado CLF, Tanaka H, Ferrari R Abstract The aim of the present study was to determine the acute effects of a muscle power training (PT) session on arterial blood pressure (BP) in older adults with hypertension. Thirteen participants (64 ± 4 years) with essential hypertension were randomly assigned to a PT session and control session without exercise. During PT, the participants performed three sets of eight repetitions at 50% of the one-repetition maximum tests. The concentric phase during each repetition was performed as fast as possible. The systolic BP (post-15 min: -1.7 &...

Obstacle-Crossing Task-Related Usual Gait Patterns of Older Adults Differentiating Falls and Gait Ability.
Authors: Ko SU, Jerome GJ, Simonsick EM, Ferrucci L Abstract Obstacle crossing, such as stepping over a curb, exerts additional demands on balance control, and therefore the study of usual-pace gait patterns associated with obstacle-crossing performance may provide additional insight into understanding falls and deterioration of gait in older adults. Participants included 432 adults aged 60-96 years (218 women). Participants who failed the obstacle-crossing task (n = 181) walked slower with smaller knee range of motion than participants who successfully completed the obstacle-crossing task (all ps

Adding Light Touch While Walking in Older Adults: Biomechanical and Neuromotor Effects.
This study examined the effects of added haptic input via light touch on a railing while walking. Participants (N = 53, 75.9 ± 7.9 years) walked normally or in tandem (heel to toe) with and without haptic input. During normal walking, adding haptic input resulted in a more cautious and variable gait pattern, reduced variability of center of mass acceleration and margin of stability, and increased muscle activity. During tandem walking, haptic input had minimal effect on step parameters, decreased lower limb muscle activity, and increased cocontraction at the ankle closest to the railing. Age was correlated with step...

Examining the Relationship Between Mental Skills and Grit in Senior Olympic Athletes.
This study examined the relationship between mental skills use by Senior Olympic Games participants and their grit, or passion and perseverance, toward a long-term goal. The participants in the Arizona Senior Olympic Games (n = 304) completed an online survey of mental skills use (Athletic Coping Skills Inventory) and grit (Grit Scale-Short). Based on the ongoing validity and reliability issues of the Grit Scale-Short, two regression models were examined, with consistency of interests (passion) and perseverance of effort (perseverance) as dependent variables. After controlling for age and sex, mental skills accounted for 1...
