Degree and pattern of dual-task interference during walking vary with component tasks in people after stroke: a systematic review.

Questions: What are the degree and pattern of dual-task interference during walking in people after stroke? How do these vary with disease chronicity and different component tasks in people after stroke? How does dual-task interference differ between people after stroke and people without stroke?

Design: Systematic review with meta-analysis of studies reporting gait-related dual-task interference.

Participants: People after stroke and people without stroke.

Outcome Measures: Measures of walking and secondary (cognitive or manual) task performance under dual-task conditions relative to those under single-task conditions.

Diagnosis of sarcopenia by evaluating skeletal muscle mass by adjusted bioimpedance analysis validated with dual-energy X-ray absorptiometry.

Background: This study aimed to adjust and cross-validate skeletal muscle mass measurements between bioimpedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) for the screening of sarcopenia in the community and to estimate the prevalence of sarcopenia in Hong Kong.

Methods: Screening of sarcopenia was provided to community-dwelling older adults. Appendicular skeletal muscle mass (ASM) was evaluated by BIA (InBody 120 or 720) and/or DXA.

Reliability and Validity of Ultrasound Elastography for Evaluating Muscle Stiffness in Neurological Populations: A Systematic Review and Meta-Analysis.

Objective: Ultrasound elastography is an emerging diagnostic technology used to investigate the biomechanical properties of the musculoskeletal system. The purpose of this study was to systematically review the psychometric properties of ultrasound elastography techniques for evaluating muscle stiffness in people with neurological conditions.

Methods: A systematic search of MEDLINE, EMBASE, CINAHL, and Cochrane Library databases was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Association of subsequent falls with evidence of dual-task interference while walking in community-dwelling individuals after stroke.

Objective: The aim of this study was to examine the fall predictive value of single-task walking tests and extent of interference observed in dual-task walking tests in ambulatory individuals post stroke.

Design: This is an observational study with prospective cohort.

Setting: The study was conducted at the university laboratory.

Cognitive-motor interference in walking after stroke: test-retest reliability and validity of dual-task walking assessments.

Objective: To explore the reliability and validity of a series of dual-task mobility assessments among individuals post-stroke.

Design: Observational study with repeated measures.

Setting: University laboratory.
