Parameters that remain consistent independent of pausing before gait-initiation during normal rise-to-walk behaviour delineated by sit-to-walk and sit-to-stand-and-walk.

Rising-to-walk is an everyday transitional movement task rarely employed in gait rehabilitation. Sit-to-walk (STW) and sit-to-stand-and-walk (STSW), where a pause separates sit-to-stand and gait-initiation (GI) represent extremes of rising-to-walk behaviour. Delayed GI can indicate pathological impairment but is also observed in healthy individuals. We hypothesise that healthy subjects express consistent biomechanical parameters, among others that differ, during successful rising-to-walk task performance re...

Reliability, validity and minimal detectable change of 2-minute walk test, 6-minute walk test and 10-meter walk test in frail older adults with dementia.

Walk tests are commonly used to evaluate walking ability in frail older adults with dementia but their psychometric evidence in this population is lacking.

Langevin dynamics for a Lévy walk with memory.

Memory effects, sometimes, cannot be neglected. In the framework of continuous-time random walk, memory effect is modeled by the correlated waiting times. In this paper, we derive the two-point probability distribution of the correlated waiting time process, as well as the one of its inverse process, and present the Langevin description of Lévy walk with memory. We call this model a Lévy-walk-type model with correlated waiting times. Based on the built Langevin picture, the properties of aging and nonstat...

Two-minute walk tests demonstrate similar age-related gait differences as a six-minute walk test.

The six-minute walk test (6MWT) is used within clinical and research settings to assess gait performance across a variety of conditions and populations. Commonly, the test is used to identify specific aspects of gait that affect functional mobility. With the advancement of new technologies such as wireless inertial sensors, it has become possible to collect reliable, sensitive, and objective measures of gait. While the 6MWT has been accepted and used for many years, a more concise, while still objective gai...

A prospective, longitudinal study evaluating the baseline six-minute walk test as an individual reference value in systemic sclerosis patients.

Interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH) are the leading causes of death in systemic sclerosis (SSc). Although the six-minute walk test (6MWT) is used for evaluating ILD and PAH, no data are available on the evolution of the six-minute walk distance (6MWD) in SSc patients without ILD and PAH and whether the baseline 6MWD could serve as individual reference value for the management of those who will develop PAH or ILD.

Functional Exercise Capacity Evaluated by Timed Walk Tests in Myasthenia Gravis.

We aimed to evaluate the test-retest reliability and construct validity of the six-and two-minute walk tests (6mWT and 2mWT, respectively) in myasthenia gravis (MG) patients.

Should the 6-minute walk test be stopped if oxyhemoglobin saturation falls below 80%?

To examine the occurrence of adverse events in patients undergoing assessment for pulmonary rehabilitation when a 6-minute walk test (6MWT) continues despite desaturation below 80%.

Association of walk ratio during normal gait speed and fall in community-dwelling elderly people.

Walk ratio (WR), calculated by dividing step length by cadence, can be used to represent the gait characteristics of human beings to maintain their gait speed.

Profile of medicines used via oral and gastrointestinal catheter in a Walk-in Service.

To identify the profile of drugs prescribed via oral and gastrointestinal catheter in a Walk-in Service of a University Hospital.

Sit-to-walk performance in Parkinson's disease: A comparison between faller and non-faller patients.

Falls are one of the main concerns in people with Parkinson's disease, leading to poor quality of life and increased mortality. The sit-to-walk movement is the most frequent postural transition task during daily life and is highly demanding in terms of balance maintenance and muscular strength.

Healthcare staff's evaluation of a walk-in centre at a healthcare centre in an immigrant-dense area.

To evaluate a walk-in centre at a healthcare centre in an immigrant-dense area where a high proportion of the patients have limited language ability in Swedish, from the perspective of healthcare personnel.

Walking for better outcomes and recovery: The effect of WALK-FOR in preventing hospital-associated functional decline among older adults.

In-hospital immobility of older adults is associated with hospital-associated functional decline (HAFD). This study examined the WALK-FOR program's effects on HAFD prevention.

Supervised and extended restart in random walks for ranking and link prediction in networks.

Given a real-world graph, how can we measure relevance scores for ranking and link prediction? Random walk with restart (RWR) provides an excellent measure for this and has been applied to various applications such as friend recommendation, community detection, anomaly detection, etc. However, RWR suffers from two problems: 1) using the same restart probability for all the nodes limits the expressiveness of random walk, and 2) the restart probability needs to be manually chosen for each application without ...

Six-minute walk test is reliable and sensitive in detecting response to therapy in CIDP.

The current clinical measures (ONLS, R-ODS, mRS, and MRC) may not be so sensitive in capturing minimal variations or measuring fatigue in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Our aim was to assess if 6-min walk test (6MWT) is able to increase the sensitivity in detecting response to therapy and to capture fatigue in CIDP patients.

Minimal Clinically Important Difference of the 6-Minute Walk Test in People With Stroke.

The 6-minute walk test (6MWT) is commonly used in people with stroke. The purpose of this study was to estimate the minimal clinically important difference (MCID) of the 6MWT 2 months poststroke.

Measurement of Dynamic Hyperinflation During the 6-Minute Walk Test Using a Mobile Device.

Dynamic hyperinflation is a major cause of dyspnea in patients with COPD. Dynamic hyperinflation is usually measured with cardiopulmonary exercise testing, but this test requires maximal effort from the patient, and inspiratory capacity (IC) measurements may influence test results. This study investigated another approach by measuring dynamic hyperinflation during the more natural and better-tolerated 6-min walk test (6MWT), using a mobile system for IC measurements.

Developmental Trajectories and Reference Percentiles for the 6-Minute Walk Test for Children With Cerebral Palsy.

The purposes of this study were to document longitudinal developmental trajectories in 6-minute walk test (6MWT) distances and to develop age-specific reference percentiles for children across different Gross Motor Function Classification System (GMFCS) levels.

Six-minute walk distance and survival time in patients with idiopathic pulmonary fibrosis in Brazil.

To determine the cut-off point for the six-minute walk distance (6MWD) that indicates lower survival time in patients with idiopathic pulmonary fibrosis (IPF) in Brazil.

Changes to gait speed and the walk ratio with rhythmic auditory cuing.

Step length and cadence (i.e., step frequency or steps/minute) maintain an invariant proportion across a range of walking speeds, known as the walk ratio (WR = step length/cadence). While step length is a difficult parameter to manipulate, cadence is readily modifiable using rhythmic auditory cuing (RAC; e.g., synchronizing step timing to a metronome or music tempo).

Random Walk Enzymes: Information Theory, Quantum Isomorphism and Entropy Dispersion.

Activation-induced deoxycytidine deaminase (AID) is a key enzyme in the human immune system. AID binds to and catalyzes random point mutations on the immunoglobulin (Ig) gene, leading to diversification of the Ig gene sequence by random walk motions, scanning for cytidines and turning them to uracils. The mutation patterns deposited by AID on its substrate DNA sequences can be interpreted as random binary words, and the information content of this stochastically-generated library of mutated DNA sequences ca...

Concurrent validity of the GAITRite electronic walkway and the 10-m walk test for measurement of walking speed after stroke.

Walking speed is used to assess functional status, predict recovery, prescribe exercise, and track functional progress after stroke. Determining concurrent validity ensures that results from different tests of walking speed can be compared or used interchangeably. The GAITRite electronic walkway and the 10-m walk test (10MWT) are popular measurement tools of walking speed in the laboratory and in clinical settings, respectively.

The effect of fear of falling on prefrontal cortex activation and efficiency during walking in older adults.

Neural inefficiency is inferred when higher brain activations are associated with similar or worse performance. Improved neural efficiency is achieved when task-related brain activations are reduced after practice. No information is available on the effect of fear-of-falling (FOF) on brain activation during walking. We hypothesized that the presence of FOF would be associated with neural inefficiency and with a delay in improving neural efficiency during dual-task walking. Task conditions included single-ta...

A prediction method of speed-dependent walking patterns for healthy individuals.

Gait speed is one of the main biomechanical determinants of human movement patterns. However, in clinical gait analysis, the effect of gait speed is generally not considered, and people with disabilities are usually compared with able-bodied individuals even though disabled people tend to walk slower.

Motor behavior characteristics in various phases of bipolar disorder revealed through biomechanical analysis: Quantitative measures of activity and energy variables during gait and sit-to-walk.

Abnormal motor behaviors influenced by high or low energy states are key signs and symptoms for mania/hypomania or depression, respectively. Clinical evaluation is currently based on qualitative, subjective self-reports. We aimed to objectively quantify activity and energy variables during gait and sit-to-walk in bipolar disorder. Gait and sit-to-walk were analyzed in 31 individuals with bipolar disorder (five hypomanic, 14 euthymic and 12 depressed) and 14 healthy controls using a motion capture system and...
