BACKGROUND AND PURPOSE: Cognition and level of physical activity have been associated with frailty syndrome. The development of tools that assess deficits related to physical and cognitive frailties simultaneously are of common interest. However, little is known about how much these aspects influence the performance of dual-task tests. Our aims were (a) to verify the influence of frailty syndrome and objectively measured physical activity and cognition on the Timed Up and Go (TUG) test and Timed Up and Go associated with dual-task (TUG-DT) performances; and (b) to compare TUG and TUG-DT performances between older adults who develop frailty syndrome...

BACKGROUND: Daily living requires the ability to perform dual-tasking. As cognitive skills decrease in dementia, performing a cognitive and motor task simultaneously become increasingly challenging and subtle gait abnormalities may even be present in pre-dementia stages. Therefore, a dual-tasking paradigm, such as the Timed Up and Go-Dual Task (TUG-DT), may be useful in the diagnostic assessment of mild cognitive impairment (MCI). OBJECTIVE: To investigate the diagnostic and prognostic ability of a dual-tasking paradigm in patients with MCI or mild Alzheimer's disease (AD) and to evaluate the association between the dual-tasking paradigm and cerebrospinal fluid (CSF) AD biomarkers...

OBJECTIVES: Few studies examine the relationship between Timed Up-and-Go (TUG), a commonly used clinical test, and cognitive decline. This study examines whether TUG, usual gait speed (UGS), and dual-task gait speed (DTGS) predict decline in global cognition, executive function, processing speed, memory, and attention with follow-up of up to 5.9 years. DESIGN: Longitudinal study. SETTING: The Irish Longitudinal Study on Ageing (TILDA), a nationally representative cohort study...

BACKGROUND: Accurate fall screening tools are needed to identify those multiple sclerosis (MS) patients at high risk of falling. The present study aimed at determining the validity of a series of performance-based measures (PBMs) of lower extremity functions and patient-reported outcomes (PROs) in predicting falls in a sample of MS patients (n = 84), who were ambulatory independent. METHODS: Patients were assessed using the following PBMs: timed up and go (TUG), timed 25-foot walk (T25FW), cognitive T25FW, 2-min walk (2MW), and cognitive 2MW...

To investigate the effects of a cell phone texting task on an individual's ability to perform three ambulation-based tasks, each with different and progressively more difficult demands. 36 participants (24 male/12 female, average age 23.4) performed: a Timed Up & Go (TUG), stair ambulation (STAIR), and tandem gait (TAN). Participants completed each gait-based task under four conditions: as a practice, while holding their cellular device (baseline), while texting a message, and while reading a message. Statistically significant differences were found within the following variables: 1) mean time to complete a gait task increased through the conditions (Baseline, Texting, Reading), 2) mean number of gait deviations increased while texting during TAN condition in comparison to baseline, 3) mean characters per second became less only in the STAIR task, 4) mean number of texting errors per second increased only in the TAN task...

Devices and sensors for identification of fallers can be used to implement actions to prevent falls and to allow the elderly to live an independent life while reducing the long-term care costs. In this study we aimed to investigate the accuracy of Timed Up and Go test, for fallers' identification, using fusion of features extracted from accelerometer data. Single and dual tasks TUG (manual and cognitive) were performed by a final sample (94% power) of 36 community dwelling healthy older persons (18 fallers paired with 18 non-fallers) while they wear a single triaxial accelerometer at waist with sampling rate of 200Hz...

Protein motors, such as kinesins and dyneins, bind to a microtubule and travel along it in a specific direction. Previously, it was thought that the directionality for a given motor was constant in the absence of an external force. However, the directionality of the kinesin-5 Cin8 was recently found to change as the number of motors that bind to the same microtubule is increased. Here, we introduce a simple mechanical model of a microtubule-sliding assay in which multiple motors interact with the filament. We show that, due to the collective phenomenon, the directionality of the motor changes (e...

BACKGROUND AND PURPOSE: The adverse effects of drugs may influence results on tests of mobility and balance, but the drug-specific impact is not identified when using these tests. We propose that a quantitative drug index (QDI) will assist in assessing fall risk based on these tests, when combined with other fall risk variables. METHODS: Fifty-seven community-dwelling older adults who could walk independently on a treadmill and had Mini-Mental State Examination (MMSE) scores equal to or greater than 24 participated...

Association between cognitive impairment and gait performance occurs in mild cognitive impairment (MCI) and Alzheimer's disease (AD), particularly under "divided attention" conditions, leading to a greater risk of falls. We studied 36 controls, 42 MCI, and 26 mild AD patients, using the Timed Up-and-Go test (TUG) under four conditions: TUG single - TUG1; TUG cognitive - TUG2; TUG manual -TUG3; TUG cognitive and manual - TUG4. Cognition was assessed using the MMSE, SKT, Exit25, and TMT (A and B). We found significant correlations between cognitive scores and TUG2 [r values (MMSE: -0...

OBJECTIVE: Gait disorders is the most common and disabling dysfunction in patient with multiple sclerosis (PwMS). Several studies have been using gait parameters to determine the interventional effects in PwMS. However, few studies interested initially to determine reproducibility of these parameters which could overestimate effects. The aim of the study was to examine the reproducibility in different spatio-temporal parameters of gait measured during short and long distances. MATERIAL/PATIENTS AND METHODS: Fifty-eight PwMS (EDSS 4-7) and 19 healthy peers were included in this study...

INTRODUCTION: The freezing of gait (FOG) is a common and highly distressing motor symptom in patients with Parkinson's Disease (PD). Effective management of FOG is difficult given its episodic nature, heterogeneous manifestation and limited responsiveness to drug treatment. METHODS: In order to verify the acceptance of a smartphone-based architecture and its reliability at detecting FOG in real-time, we studied 20 patients suffering from PD-related FOG. They were asked to perform video-recorded Timed Up and Go (TUG) test with and without dual-tasks while wearing the smartphone...

BACKGROUND: The cognitive timed up-and-go dual task (CogTUG) has been proposed to improve the performance of the timed up-and-go (TUG) test for predicting falls in older patients and as a screening tool for early detection of frailty. We aimed to determine whether the CogTUG score is associated with a history of falls in frail older outpatients with gait disorders. METHODS: This retrospective study involved outpatients >75 years old with or without previous falls who were admitted from 2012 to 2014 to a geriatric day hospital for gait disorders...

Timed UP and Go Test (TUG) is conventionally used as predictor of falls in adults. Routine daily activities include multiple tasks performed concurrently. When two or more tasks (Dual/Triple test) needed to be carried out concurrently, task performance declined at least in one of them. Our study aimed to find temporal and demographic variations in the performance after adding a cognitive, motor or both tasks, while performing TUG, compared to performance during conventional TUG. Sixty randomly selected healthy adults, with age ranging from 53 to 90 years, consented to participate in the study...

AIM: The Timed Up and Go test (TUG) is used as a measure of functional ability in older adults; however, the method of measurement does not allow us to determine which aspects of the test deficits occur in. The aim of the present study was to examine the ability of the quantitative TUG (QTUG) to measure performance during the TUG test under three different conditions - single task, motor task and cognitive dual task - and to compare performance between fallers and non-fallers in high-functioning community-dwelling older adults...

Osteoporosis is a serious disease characterized by muscle weakness in the lower extremities, shortened length of trunk, and increased dorsal kyphosis leading to poor balance performance. Although balance impairment increases in adults with osteoporosis, falls and fall-related injuries have been shown to occur mainly during the dual-task performance. Several studies have shown that dual-task performance was improved with specific repetitive dual-task exercises. INTRODUCTION: The aims of this study were to compare the effect of single- and dual-task balance exercise programs on static balance, dynamic balance, and activity-specific balance confidence in adults with osteoporosis and to assess the effectiveness of dual-task balance training on gait speed under dual-task conditions...

BACKGROUND: Parkinson's disease (PD) progressively impairs motor and cognitive function. Gait dysfunction in PD is exacerbated during dual task gait. Transcranial direct current stimulation (tDCS) may therapeutically benefit motor and cognitive deficits. We examined the effect of a bilateral tDCS protocol on dual task gait in people with PD. MATERIAL AND METHODS: Participants with PD between 50 and 80 years received two sessions of tDCS protocol (1 active, 1 sham) separated by 7days...

Human breathing stems from automatic brainstem neural processes. It can also be operated by cortico-subcortical networks, especially when breathing becomes uncomfortable because of external or internal inspiratory loads. How the "irruption of breathing into consciousness" interacts with cognition remains unclear, but a case report in a patient with defective automatic breathing (Ondine's curse syndrome) has shown that there was a cognitive cost of breathing when the respiratory cortical networks were engaged...
