Abstract Background The relationship between falls and static and dynamic postural control has not been established in Parkinson’s disease (PD). The purpose was to compare the compensatory postural strategies among fallers and non-fallers with PD as well as older adults during static and dynamic movements. Methods Twenty-five individuals with PD (11 fallers) and 17 older adults were outfitted with 6 accelerometers on the wrists, ankles, lumbar spine, and sternum, stood quietly for 30 s on a forc...

: We aimed to determine the effects of levodopa medication on the performance of a repetitive pointing task while standing, and to investigate the optimal trial duration in individuals with Parkinson's disease, and older adults. Seventeen individuals with Parkinson's disease (5 freezers) and 9 older adults stood on force platforms for 30 s and 120 s while performing a bilateral repetitive pointing task, tracked by motion capture. Participants with Parkinson's disease were assessed on and off med...

The purpose of this study was to investigate obstacle clearance and reaction time parameters when crossing a series of six obstacles in older adults. A second aim was to examine the repeated exposure of this testing protocol once per week for 5 weeks. In total, 10 older adults (five females; age: 67.0 ± 6.9 years) walked onto and over six obstacles of varying heights (range: 100–200 mm) while completing no reaction time, simple reaction time, and choice reaction time tasks once per week for 5 we...

The purpose of this study was to determine whether balance and mobility training (BMT) or balance and mobility plus cognitive training (BMT + C) would improve obstacle clearance and reaction time (RT); whether further improvements would be exposed in the BMT + C group relative to the BMT group; and whether possible improvements would be sustained at the follow-up. Healthy older adults were allocated to the BMT (n = 15; age: 70.2 ± 3.2), BMT + C (n = 14; age: 68.7 ± 5.5), or control group (n = 13...

Background and aims The purpose was to explore the impact of balance and mobility training (BMT), balance and mobility plus cognitive training (BMT + C) and no training on the timed up and go (TUG), TUG cognitive (TUGcog), and TUG manual (TUGman) in older adults. A preliminary experiment examined the stability of these TUG measures over a 5-week period in older adults.

Abstract Directing attention away from postural control and onto a cognitive task affords the emergence of automatic control processes. Perhaps the continuous withdrawal of attention from the postural task facilitates an automatization of posture as opposed to only intermittent withdrawal; however this is unknown in the aging population. Twenty older adults (69.9 ± 3.5 years) stood with feet together on a force platform for 60 s while performing randomly assigned discrete and continuous cognitiv...

Background The Fukuda stepping and Babinski-Weil tests are associated with unperceived body rotation and linear displacements in young adults, but performance in older adults on these two tests has yet to be determined.

Abstract Background and aims The purpose was to determine whether balance and mobility training (BMT) or balance and mobility plus cognitive training (BMT + C) would reduce postural sway and reaction time (RT) and maintain these improvements after a 12-week follow-up in healthy older adults. Methods Participants were allocated to the BMT (n = 15; age: 70.2 ± 3.2), BMT + C (n = 14; age:68.7 ± 5.5), or control group (n = 13; age: 66.7 ± 4.2). The BMT group trained one-on-one, 3×/wk for 12 weeks on...

Biofeedback has been shown to minimize body sway during quiet standing. However, limited research has reported the optimal sensitivity parameters of visual biofeedback related to the center of pressure (COP) sway. Accordingly, 19 young adults (6 males; 13 females; aged 21.3 ± 2.5) stood with feet together and performed three visual biofeedback intensities [unmodified biofeedback (UMBF), BF magnified by 5 (BF5), BF magnified by 10 (BF10)], along with control trials with no biofeedback (NBF). The ...

Research suggests that postural control synergies are sensitive to cognitive manipulations; however, the impact of different types of cognitive tasks on postural control remains inconclusive. The authors examined the effect of discrete and continuous tasks on postural control. Sixteen healthy young adults (M age = 22.7 ± 2.2 years) stood with feet together on a force platform while performing randomly assigned discrete and continuous cognitive tasks. Results demonstrated marked improvements in t...
