AI Article Synopsis
- The study assessed the reliability of a seated Functional Rotation Test for people with Parkinson's disease, focusing on hand-pointing and body rotation.
- It involved 10 male participants with an average age of 70.5 years, who performed the test twice to evaluate consistency.
- Results showed excellent reliability and agreement with an electrogoniometer, indicating that the Functional Rotation Test is a valid method for measuring rotation in this population.
Article Abstract
This study established the test-retest reliability of a seated Functional Rotation Test monitoring hand-pointing, together with head and trunk-rotation performance, in people with Parkinson's disease. An ancillary purpose was to establish the concurrent validity between the Functional Rotation Test and an electrogoniometer. 10 males with Parkinson's disease (M age=70.5 yr.; Hoehn and Yahr staging severity ranging from II to IV) were recruited. Subjects were fitted with laser-pointing devices, sat in the Functional Rotation room, and were instructed to turn actively and point to their right (or left) as far as they could comfortably manage. Tagged projections were scored (in degrees). Testing was repeated after a brief interval. Electrogoniometer projected locations were compared with Functional Rotation Test scores. Intraclass correlation coefficients (.91 to .97) indicated excellent test-retest reliability. There was also excellent agreement between electrogoniometric and Functional Rotation Test values (Intraclass correlation coefficients=.99). Thus the Functional Rotation Test provides a replicable measure of axial rotation of head, trunk, and hand-pointing in seated subjects with Parkinson's disease.

Objectives: To form a unique body weight support-Tai Chi Yunshou (BWS-TCY) training method, apply it to the treatment of upper limb dysfunction after stroke, and provide a new safe and effective treatment method for the clinic.
Methods: A total of 93 subjects were recruited and randomly divided into conventional rehabilitation treatment (CRT) group, BWS-TCY group and traditional robot-assisted training (RAT) group in equal proportions. Subjects in the CRT group received 60 minutes of CRT daily.
Analysis of performance degradation of an active pretensioning seatbelt in a real-world vehicle braking test.

Objective: Previous research has established the effectiveness of active pretensioning seatbelts (APS), also termed motorized pretensioning seatbelts, in mitigating forward leaning and out-of-position displacement during pre-crash scenarios. In the Chinese market, APS trigger times are typically set later than those reported in the literature. This study investigates the real-world performance of APS systems with delayed trigger times under emergency braking conditions.

Growing evidence suggests that ribosomes selectively regulate translation of specific mRNA subsets. Here, quantitative proteomics and cryoelectron microscopy demonstrate that poxvirus infection does not alter ribosomal subunit protein (RP) composition but skews 40S rotation states and displaces the 40S head domain. Genetic knockout screens employing metabolic assays and a dual-reporter virus further identified two RPs that selectively regulate non-canonical translation of late poxvirus mRNAs, which contain unusual 5' poly(A) leaders: receptor of activated C kinase 1 (RACK1) and RPLP2.

Background: Stronger default mode (DMN) and bilateral frontoparietal control network (FPCN) resting-state functional connectivity are associated with reduced β-amyloid (Aβ)-related cognitive decline in cognitively unimpaired older adults, who were predominantly Aβ negative. This suggests that these networks might support cognitive resilience in the face of early AD pathology but it remains unclear whether these effects are apparent in preclinical AD. We investigated whether left-FPCN, right-FPCN, and DMN connectivity moderated the effect of Aβ on cognitive decline using a large multi-site dataset from the Anti-Amyloid Treatment in Asymptomatic Alzheimer's Disease (A4) study.

Background: Harmonized neuropsychological battery for research in Alzheimer's disease and related dementia (ADRD) in sub-Sahara Africa is very important if we are to understand ADRD phenotype and mechanisms in the region and how they relate and differ from other regions. No study in Nigeria has examined factor structure (construct validity) at both exploratory and confirmatory levels of harmonized neuropsychological battery for research in Nigeria. This study was a move in this direction using already established neuropsychological test battery the Uniform Data Set Neuropsychological Battery version 3 (UDSNB 3.
