The purpose of this study was to determine the relationship between the results of the dual-task Timed Up and Go test and the clinical outcomes in patients with chronic dizziness/vertigo. A total of ...18 patients with dizziness/vertigo were included in the study. The patients were evaluated by the Timed Up and Go test (TUG), dual-task Timed Up and Go test (TUGdt), Dizziness Handicap Inventory (DHI), Activities-Specific Balance Confidence Scale (ABC scale), Dynamic Gait Index (DGI), and Functional Gait Assessment (FGA). The difference between the results of TUG and TUGdt was defined as ΔTUG. We analyzed the correlation between the results of each evaluation using Pearson product-moment correlation and Spearman's rank correlation coefficient. Significant correlations were found between the results of TUG-TUGdt, TUG-FGA, TUGdt-ΔTUG, ΔTUG-ABC scale, and DGI-FGA. Dual task during gait was found to be related to the self-efficacy in activities of daily living. Dual task during gait could be influenced by psychological factors. TUGdt may be useful to assess the gait performance reflecting psychological aspects.
Introduction
There are no validated, practical, and quantitative measures of disease severity in Lambert‐Eaton myasthenia (LEM).
Methods
Data from the Effectiveness of 3,4‐Diaminopyridine in ...Lambert‐Eaton Myasthenic Syndrome (DAPPER) trial were analyzed to assess triple timed up‐and‐go (3TUG) reproducibility and relationships between 3TUG times and other measures of LEM severity.
Results
The coverage probability technique showed ≥0.90 probability for an acceptable 3TUG difference of ≤0.2, indicating that it is reproducible in LEM patients. The correlation between 3TUG times and lower extremity function scores was significant in subjects who continued and in those who were withdrawn from 3,4‐diaminopyridine free base. Worsening patient‐reported Weakness Self‐Assessment Scale and Investigator Assessment of Treatment Effect scores corresponded with prolongation of 3TUG times.
Discussion
The 3TUG is reproducible, demonstrates construct validity for assessment of lower extremity function in LEM patients, and correlates with changes in patient and physician assessments. These findings, along with prior reliability studies, indicate 3TUG is a valid measure of disease severity in LEM.
Introducción: Los sujetos con Artritis Reumatoidea (AR) tienen un elevado riesgo de caídas respecto a la población sana. El Timed Up and Go Test (TUG) es utilizado para predecir el riesgo de caídas ...pero no ha sido validado en sujetos con AR. Objetivos: El objetivo primario fue establecer la validez predictiva y la validez concurrente a velocidad habitual y máxima segura en sujetos con diagnóstico de AR. El objetivo secundario fue establecer si el TUG tiene mayor valor predictivo evaluado a velocidad habitual o a velocidad máxima segura. Sujetos y método: Los sujetos fueron ingresados mediante muestreo no probabilístico consecutivo. Para la validez concurrente se correlacionó el TUG con la Berg Balance Scale (BBS) y el Test de Marcha de 10 metros (TM10m). La validez predictiva fue calculada utilizando curva de características operativas para el receptor y el área bajo la curva. Resultados: Se evaluaron 115 participantes para la validez concurrente y 98 para la predictiva. Las correlaciones entre el TUG a velocidad habitual y el TUG a velocidad máxima segura con la BBS y el TM10m resultaron fuertes (rango de -0,65 a -0,78). La capacidad predictiva del TUG resultó baja tanto a velocidad habitual como a velocidad máxima segura. Conclusión: El TUG en sus dos versiones presentó una fuerte validez concurrente al ser comparado con la BBS y el TM10m. El TUG presentó una baja validez predictiva tanto a velocidad habitual como a velocidad máxima segura para predecir el riesgo de caídas en sujetos con AR.

ABSTRACT
Introduction
We report the reliability of a new measure, the triple‐timed up‐and‐go (3TUG) test, for assessing clinical function in patients with Lambert‐Eaton myasthenia (LEM).
Methods
...Intrarater reproducibility and interrater agreement of the 3TUG test were assessed in 25 control participants, 24 patients with non‐LEM neuromuscular disease, and 12 patients with LEM. The coverage probability (CP) method was the primary measure of reproducibility and agreement. The a priori acceptable range was < 20% difference in 3TUG test times and a CP ≥0.90 confirmed agreement.
Results
CP values > 0.90 for intrarater and interrater tests confirmed acceptable reproducibility and agreement for all groups.
Discussion
The 3TUG test is a quick, noninvasive, and reproducible measure that is easy to perform, measures clinically important weakness in LEM patients, and requires little training. Additional evaluation in a larger number of LEM patients is in progress to validate the 3TUG test as a clinical measure in LEM. Muscle Nerve 57: 136–139, 2017
Zusammenfassung. Zur exakten Erfassung von Schmerzen, funktionellen Einschränkungen und gesundheitsbezogener Lebensqualität bei Patienten mit degenerativen Wirbelsäulenerkrankungen existiert eine ...Reihe validierter Messinstrumente. Neben der Beurteilung durch den Therapeuten sowie «subjektiven» patientenorientierten Messmethoden (PROMs) wurde in den vergangenen Jahren der «Timed Up and Go»(TUG)-Test systematisch untersucht und als krankheitsspezifisches Messinstrument validiert. Heute kann eine objektive funktionelle Einschränkung (OFI = Objective Functional Impairment) in wenigen Sekunden und kostenfrei mithilfe einer Smartphone-Applikation bestimmt werden. Die Bestimmung von Z- oder T-Werten, die TUG-Testergebnisse in Relation zur Populationsnorm setzen, ermöglichen eine alters- und geschlechtsadjustierte Ergebnisinterpretation. Diese Übersichtsarbeit fasst die aktuellen Erkenntnisse zu objektiven Messmethoden bei degenerativen Wirbelsäulenpathologien inklusive deren Vor- und Nachteile zusammen und vergleicht sie mit den bisherigen Beurteilungsmethoden für funktionelle Outcomes.
The purpose of this study was to investigate a range of selected physical measures for their relative contributions and extent to which they may explain the performance of the Timed “Up and Go” test ...(TUG) in a sample of healthy older adults. The participants where 194 adults aged 65 and older with no cognitive impairment and independent in their daily activities from local senior centres and a geriatric nursing home in Valencia, Spain. Age, body mass index (BMI), TUG, Berg balance scale (BBS), One-leg stand test (OLS), grip strength, chair stand test (STS-5), knee extension strength and rectus femoris cross-sectional area (CSA) where measured. Moderate to high significant associations were found between the TUG performance and BBS and knee extension strength (r = −.561 and −.397). A stepwise multiple regression analysis showed that the BBS was a significant and independent predictor (AdjR2 = .373) for the TUG performance. The TUG is highly correlated with the BBS score and knee extension strength, measures that represent common performance tasks in everyday life. The BBS was demonstrated to be the most significant factor explaining the TUG performance. The TUG is demonstrated to be a useful tool for predicting changes in functional balance measured with the BBS. The mobility decline may be better explained as the sum of deficits across multiple domains rather than as a single entity. Clinicians would benefit of those findings by a better understanding of the physical measures, in addition to designing more accurate interventions focusing on the enhancement of mobility.
•The TUG is highly correlated with functional balance tasks common in everyday life and knee extension strength.•The BBS score explains a large proportion of variance in the TUG performance.•The TUG is an appropriate measure for predicting changes in functional balance.•Clinicians would benefit of those findings by designing more accurate interventions for the enhancement of mobility.
