Objectives: To evaluate the association between the onset of movement impairments and disability progression in nursing home residents.
Design: Retrospective cohort analysis of data from the State of New York Minimal Data Set, version 2.0, between November 1998 and October 1999. Participants were nursing home residents (n = 84,346) in the State of New York. Items defined as "functional limitation in range of motion" and "lack of voluntary movement" served as measures of movement impairments. Scores on the activities of daily living summary scale served as a measure of disability. Age, sex, measures of cognition, depression, and measures of medical stability served as adjustment variables.
Results: After adjusting for age, sex, cognition, depression, and measures of medical stability, the onset of either singular or combined movement impairments in voluntary movement or range of motion was associated with a concurrent step-wise loss in activities of daily living (P < 0.001). The progression in activities of daily living loss occurred regardless of location or limb type.
Conclusion: This study directly links the onset of movement impairments with disability progression. These findings have important implications for physiatrists and other practitioners of geriatric rehabilitation.

Background: Construct validity and responsiveness of upper limb outcome measures are essential to interpret motor recovery poststroke. Evaluating the associations between clinical upper limb measures and sensor-based arm use (AU) fosters a coherent understanding of motor recovery. Defining sensor-based AU metrics for intentional upper limb movements could be crucial in mitigating bias from walking-related activities.

Reduced cerebral blood flow occurs early in the development of Alzheimer's disease (AD), but the factors producing this reduction are unknown. Here, we ask whether genetic and lifestyle risk factors for AD-the ε4 allele of the Apolipoprotein (APOE) gene, and physical activity-can together produce this reduction in cerebral blood flow which leads eventually to AD. Using in vivo two-photon microscopy and haemodynamic measures, we record neurovascular function from the visual cortex of physically active or sedentary mice expressing APOE3 and APOE4 in place of murine APOE.

The neuromuscular junction (NMJ) is the linchpin of nerve-evoked muscle contraction. Broadly, the function of the NMJ is to transduce nerve action potentials into muscle fiber action potentials (MFAPs). Efficient neuromuscular transmission requires both cholinergic signaling, responsible for generation of endplate potentials (EPPs), and excitation, the amplification of the EPP by postsynaptic voltage-gated sodium channels (Nav1.

A 49-year-old female presented with the primary complaint of hand tremors. Neurological examination on admission revealed signs of cognitive impairment, bulbar palsy, dystonia, cerebellar ataxia, and pyramidal tract disease. T-weighted brain MRI revealed hyperintense signals in the subcortical white matter, basal ganglia, and cerebellar dentate nucleus, with no atrophy of the brainstem or corpus callosum.

Research conducted since the turn of the millennium has shown that the quality of life in patients with Tourette syndrome is affected by various health-related factors. The condition's chronic nature, along with its social and emotional implications, can significantly diminish the overall quality of life. Both core symptoms-motor and vocal tics-and associated comorbidities can contribute to functional impairments and reduced well-being.
