“…4 Elderly individuals have shown an inability to adapt their walking pattern to unexpected situations in their daily lives, which usually occur when performing several simultaneous tasks. [4][5][6] The dual-task (DT) paradigm has been in use since the middle of the 1980s and involves the performance of two concomitant tasks. It was first used in psychological studies and was later adopted by health professionals working in the areas of rehabilitation and gerontology to assess and train elderly individuals in a secondary task, with walking as the primary task.…”

“…4,14 The aging process is accompanied by alterations in the spatial and temporal parameters of gait, 14 such as reductions in gait speed and step length, as well as increases in step variability, double support time and step width, 4,12,15 all of which have been correlated with a higher incidence of falls. 5,6,[16][17][18][19][20][21] An assessment of these parameters is generally used to identify abnormalities in an individual's gait. 22 While several gait parameters (reduced speed, reduced step length and increased double support time) can reflect impairment and are correlated with a fear of falls, step variability is the indicator that provides the best representation of postural instability.…”

Introduction: The physiological deterioration associated with ageing exposes elderly persons to greater risks of falls, especially during the performance of simultaneous tasks during gait. Objectives: To evaluate the effects of dual tasks (DT) on spatiotemporal gait parameters and to identify the tools and tasks most commonly used to assess the performance of DT among the elderly. Method: Searches of the MEDLINE, PsycINFO, CINAHL, and SciELO databases were conducted. Observational studies, which evaluated gait changes during the performance of DT, published up to April 2014, were selected. Results: A total of 385 articles were found, of which 28 were selected. Decreases in speed and increases in stride variability, stride time, step width, and double support time were observed under DT conditions. Motion analysis systems, such as the GAITRite walkway® system were the mostly commonly used instruments for the analyses of kinematic parameters (16 studies). DT was most commonly assessed by arithmetic calculations in 20 studies, followed by verbal fluency, in nine studies. The gait parameters most commonly assessed were speed (19 studies), followed by stride variability (14 studies). Conclusion: The elderly showed changes in spatiotemporal gait parameters under DT conditions. Gait speed and stride variability were often assessed and, together, were considered good indicators of risks of falls.

“…Different outcome parameters from DT walking indicating a fall risk were the following: reduced walking speed, 18 changes in step width, step time, and step length, 17 or variability in stride time. 19 In chronic stroke patients, Hyndman et al 15 found that Fs showed a significantly reduced stride length during DT gait analyses compared with NFs.…”

Abstract Objectives: To evaluate fall risk in stroke patients based on single-and dual-task gait analyses, and to investigate the difference between 2 cognitive tasks in the dual-task paradigm. Design: Prospective cohort study. Setting: Rehabilitation hospitals. Participants: Subacute stroke patients (NZ32), able to walk without physical/manual help with or without walking aids, while performing a verbal task. Interventions: Not applicable. Main Outcome Measures: Functional gait measures were Functional Ambulation Categories (FAC) and use of a walking aid. Gait measures were evaluated by an electronic walkway system under single-and dual-task (DT) conditions. For the single-task, subjects were instructed to walk at their usual speed. One of the DTs was a verbal fluency dual task, whereby subjects had to walk while simultaneously enumerating as many different animals as possible. For the other DT (counting dual task), participants had to walk while performing serial subtractions. After inclusion, participants kept a 6-month falls diary. Results: Eighteen (56.3%) of the 32 included patients fell. Ten (31.3%) were single fallers (SFs), and 8 (25%) were multiple fallers (MFs). Fallers (Fs) more frequently used a walking aid and more frequently needed an observatory person for walking safely (FAC score of 3) than nonfallers (NFs). Two gait decrement parameters in counting dual task could distinguish potential Fs from NFs: decrement in stride length percentage (PZ.043) and nonparetic step length percentage (PZ.047). Regarding the division in 3 groups (NFs, SFs, and MFs), only MFs had a significantly higher percentage of decrement for paretic step length (PZ.023) than SFs. Conclusions: Examining the decrement of spatial gait characteristics (stride length and paretic and nonparetic step length) during a DT addressing working memory can identify fall-prone subacute stroke patients.

“…Current stroke patient rehabilitation assessments, whether in a clinic or at home, involve subjective, task orientated assessments. Whilst these are useful, visual observation alone cannot sufficiently characterise subtle changes to gait [3]. This is an important consideration as the progress of patient rehabilitation will inform the direction and continuation of physical therapy interventions, particularly if those interventions are home-based.…”

Abstract:Traditional motion capture systems can be prohibitive in healthcare settings from time, cost, space and user-expertise perspectives. Ideally, movement analysis technologies for healthcare should be low-cost, quick, simple and usable in small spaces. This study demonstrates a simple, low-cost and close-range time-of-flight depth-camera system, for automatic gait analysis. A method to automatically track three-dimensional position and orientation of retro-reflective marker-triads in real-time was developed. A marker-triad was applied to a participant (self-selected walking pace): thigh angle (wrt. global-vertical) was calculated. Trials were concurrently recorded using a motion capture system. Root-mean-square error was 2.5°, 1.3° and 2.2° for depth-camera distances of 0.8 m, 1.1 m and 1.4 m respectively. Results indicate that walking distances of 1.1 m are optimal for the current system. Further development and investigation into potential healthcare applications (e.g., low-cost, close-range gait analysis) is warranted.

Recurrent Falls and Dual Task–Related Decrease in Walking Speed: Is There a Relationship?

Abstract: Slower walking speed while counting backward was associated with recurrent falls, suggesting that changes in gait performance while dual tasking might be an inexpensive way of identifying frail older adults prone to falling.
