Summary: This study aimed to compare the force steadiness during low and moderate levels of knee extensor force exertion between individuals with and without Parkinson's disease (PD) and examine the association between force steadiness and postural control. The results showed that force steadiness was lower in PD patients with postural instability during low intensity force exertion, but there was no significant difference in force steadiness during moderate intensity force exertion among the three groups.

Summary: This study aimed to evaluate whether functional limitations exist in individuals with Parkinson disease before diagnosis. Using Medicare-linked data from the National Health and Aging Trends Study (NHATS) in the US, researchers found that individuals with prodromal Parkinson disease may have greater impairment in mobility and strength up to 3 years prior to diagnosis compared with the general population.

Summary: This study investigated the effects of age and attentional focus instruction on postural and supra-postural tasks among older adults with mild cognitive impairments. The results showed that external attentional focus instruction had a positive impact on postural control, and supra-postural tasks were more beneficial for postural function compared to postural tasks. Therefore, designing training programs with supra-postural tasks can improve balance in older adults with mild cognitive impairments.

Summary: Axial disability, including gait disturbances, is common in Parkinson's disease (PD), especially in advanced stages. Epidural spinal cord stimulation (SCS) has been investigated as a treatment option for gait disorders in PD. This review examines the literature on SCS in PD and evaluates its efficacy, optimal stimulation parameters, optimal electrode locations, possible effects of concurrent deep brain stimulation, and possible working mechanisms on gait.

Summary: The study aimed to assess the impact of Whole-Body Vibration (WBV) therapy on functional balance status of PD patients and compare it to conventional and combined therapy. The results showed that the combined therapy group had a greater increase in BBS score compared to conventional therapy, but no significant differences were observed compared to the WBV group.

Summary: Parkinson's disease is a neurodegenerative disorder that affects millions of people worldwide, and its incidence is expected to rise due to the aging of the global population. Exploring new technological interventions, such as social assistive robots, is important for supporting individuals with Parkinson's disease. This study aimed to understand the needs, expectations, and attitudes of individuals with Parkinson's disease and their family members toward social assistive robots.

Summary: Chronic ankle instability is a common condition after acute ankle sprains, causing loss of function, decreased postural control, strength deficit, and reduced range of motion. The validation of FAAM and FAOS in assessing muscle strength, postural control, and range of motion in adults with chronic ankle instability was investigated in this study.

Summary: Depression in drug-naive, early-stage PD patients is associated with an earlier occurrence of postural instability, suggesting shared nondopaminergic pathogenic mechanisms and potentially enabling prediction of early development of postural instability.

Summary: This experiment investigated the balance performance of people with Parkinson's disease using a standardized treadmill surface perturbation task and a clinical pull test, and examined the effects of medication and body weight support. The results showed that the treadmill test performed slightly better than the pull test in distinguishing between groups, and partial bodyweight support did not significantly degrade the sensitivity of the test to detect balance deficits in people with PD.

Summary: This study investigated the dynamics of subthalamic nucleus local field potentials (STN-LFP) in Parkinson's disease patients and found differences in low-frequency beta bursts between tremor-dominant and postural instability and gait disorder phenotypes. These differences were correlated with motor symptoms.

Summary: The study found that using an external focus (such as focusing on the platform) was more effective in improving the performance of volleyball players compared to an internal focus (focusing on the arms). This suggests that instructors can creatively use images to enhance motor skill performance in various applied settings.

Summary: This study found that fear of falling avoidance behavior (FFAB) is common among individuals with Parkinson's disease (PD), and the activities most avoided due to FFAB include walking in dimly lit, unfamiliar places, lifting and carrying objects, walking in crowded places, engaging in recreational/leisure activities, and going up/downstairs. Fallers reported more FFAB, and FFAB for certain activities was associated with increased or decreased odds of falling.

Summary: Parkinson's disease is a neurodegenerative disorder that impairs motor function. Transcranial direct current stimulation (c-tDCS) has been shown to improve motor skills. However, this study found that a single session of c-tDCS did not enhance motor skill acquisition or transfer in patients with Parkinson's disease.

Summary: The study demonstrates that an external focus improves performance and learning of motor skills compared to an internal focus. Through a golf pitch shot experiment, it is found that external focus instructions enhance skill learning, increase positive affect, reduce negative affect, and improve self-efficacy. These findings support assumptions of the OPTIMAL theory and emphasize the attentional and motivational benefits of an external focus.

Summary: This study investigated the reliability and validity of a novel battery of dual-task measures (DTE-B) in individuals with Parkinson's disease (PD), Alzheimer's disease (AD), and healthy older adults. The results showed good reliability and validity of the DTE-B in assessing changes in task interference and automaticity related to dual-task demands. Further research is needed to explore the utility of the DTE-B in other populations.
