“…A practical example of the relevance of gait speed is the velocity considered the lower limit for safely crossing a signaled zebra crossing, which is 1.22 m/s in the United States and 1.07 m/s in the United Kingdom [26,27] . In Germany, 1.2 m/s is used as a cutoff point for safely crossing signaled zebra crossings [28] .…”

Background: Among current operational definitions of frailty, the criteria proposed by Fried and colleagues have attracted great scientific interest. However, these criteria have usually been applied in epidemiological and only rarely in interventional studies. Objective: The present paper aims at testing the applicability of the Fried frailty criteria in the context of the recruitment process of a randomized controlled trial in prefrail older persons, and it discusses the respective scientific literature. Methods: Recruitment was promoted by newspaper articles as well as by targeted mail to customers of a local health insurance company and to recently treated patients of a geriatric day clinic. Furthermore, presentations were given in assisted living facilities. Potential candidates were screened for prefrailty, i.e. to see whether they met 1 or 2 of the Fried criteria (weight loss, handgrip strength, gait speed, exhaustion, physical activity). Results: A total of 298 people were screened. Among them 181 were not frail, 116 were prefrail and 1 was diagnosed as frail. The most prevalent criterion was exhaustion (24% of those screened). The second most prevalent criterion was low handgrip strength (20%). Low gait speed (8%), low physical activity (2%) and weight loss (2%) had a lower prevalence. According to the Geriatric Depression Scale, 14% of those who met the criterion ‘exhaustion’ were depressed. With regard to the Minnesota Leisure Time Physical Activity Questionnaire, used for the evaluation of ‘physical activity’, only 3 activities among the 18 selected by Fried were applicable to our cohort. Conclusions: Under the study conditions, good applicability of the Fried criteria was observed. Nevertheless, further refinement may be expedient in several criteria, especially exhaustion and physical activity, to enhance clinical usefulness. It may be helpful to adapt the cutoffs when applying the criteria to a European population.

“…Studies evaluating outcomes in cardiopulmonary disease have often used the 6MWT as the gold standard for criterion validity (14)(15)(16)(17); and other studies have established the 6MWT distance as a reliable and valid measure of functional capacity (18)(19)(20). The significance of small differences in the distance of the 6MWT may be unclear.…”

A fundamental goal of lung transplantation is the regaining of functional capacity, yet little is known about what factors are associated with the achievement of this goal. The aim of this study is to test the association of clinical risk factors with functional status 1 year following lung transplantation. We conducted a cohort study of 321 lung transplants and assessed functionality by the distance achieved during a standard 6-min walk test (6MWT). Preoperative recipient risk factors were evaluated for association with functional status and adjusted for confounding using multivariable linear regression models. In these multivariable analyses, recipient female gender (p < 0.001), recipient pretransplant body mass index (BMI) of greater than 27 kg/m 2 (p = 0.017) and shorter pretransplant 6MWT distances (p = 0.006) were independently associated with shorter distances achieved during 6MWT after lung transplant, while cystic fibrosis (CF) (p = 0.003), and bilateral lung transplant (p = 0.014) were independently associated with longer distances achieved. Approximately 51% of the variance in 6MWT distance was explained by these risk factors in the linear regression models (R 2 = 0.51). These findings may have implications in patient counseling, selection, procedure choice, and may lead to interventions aimed at improving the functional outcomes of lung transplantation.

“…Objectives of lower limb rehabilitation in hemiparesis often include an increase in gait velocity, which has been shown to be associated with an augmentation of every day ambulation [3]. The underlying mechanisms of walking speed impairment include paresis of agonist muscles, and contracture and overactivity in antagonist muscles [4].…”

Ecological Validity of Walking Speed Assessment After Traumatic Brain Injury

Abstract: Comfortable walking speed appears to have the highest ecological validity of the clinical gait tests investigated. Practice in natural and more complex environments should be incorporated into walking rehabilitation programs for people with TBI.
