Exploring the role of ankle muscle function in gait impairments and fall risk in Parkinson's disease
Exploring the role of ankle muscle function in gait impairments and fall risk in Parkinson's disease
Highlights
Ankle muscle strength and force steadiness are linked to gait variability in Parkinson's disease.
Weak ankle dorsiflexion and plantarflexion increase gait variability in Parkinson's disease.
Enhanced ankle strength could reduce fall risk and improve walking stability in persons with Parkinson's disease.
"Every Day Is a Battle": The Impact of COVID-19 on Physical Activity Behavior Among a Group of Rural Older Adults Living with Parkinson's Disease
"Every Day Is a Battle": The Impact of COVID-19 on Physical Activity Behavior Among a Group of Rural Older Adults Living with Parkinson's Disease
Highlights:
Physical activity is crucial for managing Parkinson's disease symptoms, with participants adapting PA routines during COVID-19 to maintain symptom control.
Social isolation during the pandemic increased depression, highlighting the importance of social support and connections in improving quality of life.
Future physical activity programs should prioritise psychological needs and foster social interaction, particularly in resource-limited rural areas, to ensure sustained participation and improved well-being.
Neural-Targeted Rehabilitation Strategies to Address Neuroplasticity After Joint Injury
Neural-Targeted Rehabilitation Strategies to Address Neuroplasticity After Joint Injury
Highlights:
Changes throughout the central nervous system may predispose individuals for subsequent musculoskeletal injury, especially in the case of ligament sprains; therefore, rehabilitation strategies should aim to restore typical neural activation.
In addition to typical sensory and motor interventions, clinicians could use motor learning strategies and brain stimulation to encourage integration and improve automatic movement in the treatment of ligament injury.
Affective interventions can easily be incorporated to enhance readiness for return to activity and should be further investigated in patients with musculoskeletal injury.
Combining hypoxia with thermal stimuli in humans: physiological responses and potential sex differences
Combining hypoxia with thermal stimuli in humans: physiological responses and potential sex differences
Highlights:
Thermal and hypoxic stressors at high altitudes create competing and modified physiological responses.
Research on multistressor environments is limited, especially regarding sex-specific physiological responses.
Better understanding of these responses is needed to improve guidance for women in high-altitude activities.
Effects of Prefrontal Transcranial Direct Current Stimulation on Retention of Performance Gains on an Obstacle Negotiation Task in Older Adults
Effects of Prefrontal Transcranial Direct Current Stimulation on Retention of Performance Gains on an Obstacle Negotiation Task in Older Adults
Highlights:
Sham tDCS, when combined with complex walking practice, may enhance walking performance gains more than both active tDCS and no tDCS.
Active tDCS may improve the retention of walking performance gains over time compared to no tDCS.
Additional studies with larger sample sizes and multiple sessions are needed to clarify the benefits of prefrontal tDCS on complex walking performance in older adults.
Somatosensory impairment of the feet is associated with higher activation of prefrontal cortex during walking in older adults
Somatosensory impairment of the feet is associated with higher activation of prefrontal cortex during walking in older adults
Highlights:
Poorer foot somatosensation in older adults is linked to increased prefrontal cortex activity during walking.
Greater prefrontal activity during obstacle negotiation is associated with faster walking speed, while worse somatosensation correlates with slower speeds and poorer balance.
Findings suggest somatosensory impairments may affect walking coordination, warranting further research on interventions.
Aging and Gait Function: Examination of Multiple Factors that Influence Gait Variability
Aging and Gait Function: Examination of Multiple Factors that Influence Gait Variability
Highlights:
Older adults show reduced force production and increased variability in ankle dorsiflexor and plantar flexor muscles compared to younger adults, contributing to impaired gait and balance.
Lower ankle strength and higher force variability are linked to slower walking speeds and increased gait variability, indicating age-related declines in central motor control.
Physical activity (PA) is associated with better gait and ankle function in older adults, suggesting that regular activity may help preserve mobility and prevent functional decline.
Evaluation of gait termination strategy in individuals with Essential Tremor and Parkinson's disease
Evaluation of gait termination strategy in individuals with Essential Tremor and Parkinson's disease
Highlights:
Mechanisms of gait termination were evaluated across pathological populations.
Tremor and Parkinson’s disease use different strategies for gait termination.
Those with essential tremor have decreased stability during gait termination.
The cerebellum and basal ganglia may play different roles during gait termination.
Redistribution of joint moments and dynamic balance control during sit to stand task in persons with Parkinson's disease
Redistribution of joint moments and dynamic balance control during sit to stand task in persons with Parkinson's disease
Highlights:
Sit to stand (STS) transitional task in Parkinson's disease (PD) was evaluated.
During the STS task, PD redistribute their lower extremity joint torques.
PD have decreased stability when rising from a chair.
PD rely on knee extensors during STS which could lead to decreased stability.
