AI Article Synopsis
Article Abstract
Objective: To assess the intra-/interrater reliability and the validity of the free web-based Shaw Gait Assessment Tool (with visual and numerical output) for assessing speed, cadence, step length, and limb advance time in people with hemiplegic gait.
Design: Intra-/interrater reliability and concurrent validity with 2 raters using the Shaw Gait Assessment Tool and 1 rater using a multimemory stopwatch.
Setting: Busy outpatient rehabilitation gym at a tertiary care medical center.
Participants: Convenience sample of adults with hemiplegic gait after cerebrovascular accident or traumatic brain injury.
Interventions: Not applicable.
Main Outcome Measures: Intraclass correlation coefficients (ICCs) and Pearson product-moment correlation coefficients.
Results: ICCs for intrarater reliability ranged from 0.94 (95% CI, 0.88-0.97) to 0.98 (95% CI, 0.96-0.99), (P<.001), and for interrater reliability from 0.95 (95% CI, 0.88-0.98) to 0.99 (95% CI, 0.99-0.99), (P<.001). The Shaw Gait Assessment Tool correlated with the stopwatch for all measured gait parameters with Pearson product-moment correlation coefficients (range, r=0.95 to r= 0.99, P<.001).
Conclusions: The Shaw Gait Assessment Tool is a free, easy-to-use tool that gives reliable and valid results for 4 temporospatial parameters of hemiplegic gait.

Brodalumab, a humanized monoclonal antibody that targets the interleukin-17 receptor A, is primarily used to manage moderate-to-severe plaque psoriasis. Although it has demonstrated favorable efficacy and safety in clinical trials, the strict inclusion and exclusion criteria may not fully reflect its safety profile in real-world settings. As its use becomes more widespread in clinical practice, understanding its safety in real-world applications is crucial.

The current gold standard for the study of human movement is the marker-based motion capture system that offers high precision but constrained by costs and controlled environments. Markerless pose estimation systems emerge as ecological alternatives, allowing unobtrusive data acquisition in natural settings. This study compares the performance of two popular markerless systems, OpenPose (OP) and DeepLabCut (DLC), in assessing locomotion.

Chronic non-specific neck pain (CNSNP) is a common condition and its relationship to the pain catastrophizing construct in terms of sensorimotor functions and dual task performance is not fully understood. We aimed to investigate the differences in sensorimotor integration, cervical sensorimotor control, and cognitive-motor dual tasking abilities between CNSNP patients (> 3 months) with high versus low catastrophizing tendencies and healthy controls. Ninety participants were recruited, 30 asymptomatic controls, and 60 patients with CNSNP; 30 scoring high (> 75 percentile) and 30 scoring low (< 25th percentile) on the pain catastrophizing scale (PCS).

Introduction: Detecting Freezing of Gait (FOG) poses challenges, with the subjective 6-item FOG Questionnaire relying solely on patient perception. We aim to create a holistic FOG Detection Toolkit combining subjective and objective elements (descriptions, images, and videos) to improve FOG detection precision.
Methods: Development of the FOG Detection Toolkit involved a detailed cover sheet on FOG and its triggers, along with video exemplars and a 4-item FOG-specific self-assessment questionnaire, all rigorously validated.

Background: There is growing literature examining the effects of balance training on cognitive function in individuals with multiple sclerosis (MS), yet the findings remain inconsistent. This study aimed to investigate methodological characteristics of balance training studies and examine the effects of this modality on cognitive function.
Methods: This study performed literature search using MEDLINE, EMBASE, PsycINFO, SPORTSDiscus, and CINAHL databases from inception to April 2024.
