Background: Functional near-infrared spectroscopy (fNIRS) is increasingly used in the field of posture and gait to investigate patterns of cortical brain activation while people move freely. fNIRS methods, analysis and reporting of data vary greatly across studies which in turn can limit the replication of research, interpretation of findings and comparison across works.

Research question and methods: Considering these issues, we propose a set of practical recommendations for the conduct and reporting of fNIRS studies in posture and gait, acknowledging specific challenges related to clinical groups with posture and gait disorders.

Results: Our paper is organized around three main sections: …

Passive, Yet Not Inactive: Robotic Exoskeleton Walking Increases Cortical Activation Dependent On Task, Sue Peters, Shannon B. Lim, Dennis R. Louie, Chieh-Ling Yang, Janice J. Eng

Physical Therapy Publications

Background

Experimental designs using surrogate gait-like movements, such as in functional magnetic resonance imaging (MRI), cannot fully capture the cortical activation associated with overground gait. Overground gait in a robotic exoskeleton may be an ideal tool to generate controlled sensorimotor stimulation of gait conditions like ‘active’ (i.e. user moves with the device) and ‘passive’ (i.e. user is moved by the device) gait. To truly understand these neural mechanisms, functional near-infrared spectroscopy (fNIRS) would yield greater ecological validity. Thus, the aim of this experiment was to use fNIRS to delineate brain activation differences between ‘Active’ and ‘Passive’ overground gait …

Association Between Changes In Subjective And Objective Measures Of Mobility In People With Lower Limb Amputations After Inpatient Rehabilitation, Gabrielle Cieslak, Humberto Omana, Edward Madou, Courtney Frengopoulos, Ricardo Viana, Michael W Payne, Susan W. Hunter

Physical Therapy Publications

Functional recovery for people with lower limb amputations is quantified using objective or subjective measures of performance. In this brief report, the prospective relationship between objective and subjective mobility after rehabilitation was evaluated in people with lower limb amputations. Adults undergoing inpatient prosthetic rehabilitation for a first unilateral transtibial or transfemoral level lower limb amputation were recruited. Assessment times: discharge and 4-mo follow-up. Gait velocity and the L Test under single- and dual-task conditions measured objective mobility. The Prosthetic Evaluation Questionnaire (section 4 and question 5b) measured subjective mobility. Paired t tests and Pearson correlation analysis evaluated change over time …

Effect Of Dual-Tasking On Walking And Cognitive Demands In Adults With Alzheimer's Dementia Experienced In Using A 4-Wheeled Walker, Susan W. Hunter, Humberto Omana, Edward Madou, Walter Wittich, Keith D Hill, Andrew M Johnson, Alison Divine, Jeffrey D Holmes

Physical Therapy Publications

BACKGROUND: Learning to walk with a 4-wheeled walker increases cognitive demands in people with Alzheimer's dementia (AD). However, it is expected that experience will offset the increased cognitive demand. Current research has not yet evaluated gait in people with AD experienced in using a 4-wheeled walker under complex gait situations.

RESEARCH QUESTION: What is the effect of dual-task testing on the spatial-temporal gait parameters and cognitive performance of people with AD experienced with a 4-wheeled walker?

METHODS: Twenty-three adults with mild to moderate AD (87.4 ± 6.2 years, 48 % female) and at least 6 months of walker use experience …
