Objective: To investigate the reliability and construct and criterion-related validities of the Timed Up and Go Assessment of Biomechanical Strategies (TUG-ABS), when used with subjects with hemiparesis due to stroke within clinical settings. Design/methods: Construct validity was investigated by the following methods: the known groups, convergence, discriminant analyses, and the opinions of clinical professionals, who used the TUG-ABS with subjects with stroke. The criterion-related validity was investigated by comparing the real-time and video observation scores. Inter-rater reliability was investigated by two independent examiners using both real-time and video observations. Results: The TUG-ABS differentiated people with stroke from healthy controls (p < 0.001), was correlated with the time spent to perform the TUG (r(s) = -0.85: p < 0.001), and correctly classified 98% of the subjects with stroke (p < 0.001). In addition, all of the clinicians who used the TUG-ABS in their clinical settings, provided positive evaluations. Agreement was also observed between real-time and video observations (0.27 <= kappa <= .0.85; p < 0.01). Furthermore, the TUG-ABS was reliable for both real-time (0.24 <= kappa <= 1.00; p < 0.05) and video observations (0.15 <= kappa <= 0.94; p < 0.05). Conclusion: The TUG-ABS demonstrated good construct and criterion-related validities, as well as reliability, when applied in subjects with stroke within clinical settings, which supported the theoretical assumptions employed for its development.

General and comparative self-rated health in chronic stroke: an important outcome measure for health professionals

Ramon Tavora Viana, Erika de Freitas Araujo, Lidiane Andrea Oliveira Lima, Luci Fuscaldi Teixeira-Salmela, Christina Danielli Coelho de Morais Faria

Summary: The evaluation of self-rated health (SRH) differs in individuals with chronic post-stroke disabilities depending on the types of questions and health/functioning domains.

Summary: The purpose of this study was to analyze the diagnostic capacity and accuracy of WHODAS 2.0 in stroke survivors. The results showed that a cutoff point of 39.62 was acceptable for distinguishing individuals with moderate/severe disability from those with no or mild disability, with reasonable sensitivity and specificity.

Summary: This systematic review aimed to summarize the measurement properties and the clinical utility of measurement tools used in telerehabilitation for individuals with neurological conditions. The results showed that out of the 43 identified measurement tools, 22 had sufficient measurement properties and clinical utility. Further research is needed to investigate measurement error, content validity, structural validity, and responsiveness. Rating: 8 out of 10.

Biopsychosocial factors associated with the state of disability after hemiparesis in the chronic phase of stroke: exploratory analysis based on the International Classification of Functioning, Disability and Health

Summary: This study aimed to identify the main biopsychosocial factors associated with disability level after stroke using the ICF model. A cross-sectional study was conducted with chronic stroke survivors, and disability was assessed. The results showed that limited locomotor ability, dissatisfaction regarding activities and participation, and the non-return to work were associated with disability.

Validity of the two-minute walk test to assess exercise capacity and estimate cardiorespiratory fitness in individuals after stroke: a cross-sectional study

Luana Cristina da Silva, Christina Danielli Coelho de Moraes Faria, Paula da Cruz Peniche, Sherindan Ayessa Ferreira de Brito, Larissa Tavares Aguiar

Summary: The study aimed to investigate the validity of the 2-minute walk test (2MWT) and the 6-minute walk test (6MWT) in assessing exercise capacity and cardiorespiratory fitness of individuals with chronic stroke. The study found a high correlation between the distance covered in the 2MWT and 6MWT, as well as a moderate correlation between the distance covered in the 2MWT and VO2peak. Prediction equations were developed to estimate VO2peak and the distance covered in the 6MWT.

Predictors of access to healthcare services within 1 month after stroke in a developing country: A longitudinal prospective study

Summary: In this study conducted in Brazil, a developing country, gender and education level were found to be significant predictors of access to healthcare services within one month of stroke. However, overall, patients had less access to healthcare services than recommended. This has significant implications for the health and functional outcomes of stroke survivors.

Summary: The purpose of this study was to compare the trunk biomechanical characteristics during sit-to-stand and stand-to-sit tasks in stroke survivors and healthy-matched controls. The results showed that stroke survivors had a greater range of trunk forward flexion and longer duration for both tasks.

Are age-predicted equations valid in predicting maximum heart rate in individuals after stroke?

Maria Teresa Ferreira dos Reis, Larissa Tavares Aguiar, Paula da Cruz Peniche, Christina Danielli coelho de Morais Faria

Summary: The study aimed to investigate the validity of six age-predicted maximum heart rate equations after stroke. The results showed that the equations developed for non-disabled individuals were not suitable for individuals after stroke, except for equation (6) proposed by Brawner, which showed the best results but should still be used with caution.

Access to rehabilitation professionals by individuals with stroke one month after hospital discharge from a stroke unit in Brazil is insufficient regardless of the pandemic

Jordana P. Magalhaes, Iza Faria-Fortini, Tamires M. F. Dutra, Romeu Sant'Anna, Carolina LA Soares, Luci F. Teixeira-Salmela, Christina D. C. M. Faria

Summary: This study aimed to compare access to rehabilitation professionals by individuals with stroke before and during the COVID-19 pandemic in Brazil. The findings showed that the access to rehabilitation professionals was similar between the two periods, but the actual number of accessed professionals was lower than the number of referrals. This indicates a compromised comprehensiveness of care for individuals with stroke, regardless of the pandemic.

Tereshchenko, Achilles Thoma, Alparslan Turan, Andrew Worrall, Robin Christensen, Gary S. Collins, Joseph S. Ross, Rod S. Taylor

Summary: Interventional trials that use surrogate endpoints to evaluate treatment effects are increasingly common. However, there is currently inconsistency and lack of clarity in the definition and interpretation of surrogate endpoints. Surrogate endpoints are used as substitutes for the treatment effects on ultimate outcomes of interest. While traditionally biomarkers have been the focus of surrogate endpoint consideration, intermediate outcomes that include measures of function or symptoms can also act as surrogate endpoints. However, there is a lack of consensus among stakeholders on accepting and interpreting intermediate outcomes as surrogate endpoints. Better understanding and reporting on the use of surrogate endpoints in interventional trials is urgently needed.

Summary: This study compared the sociodemographic and clinico-functional characteristics of stroke patients during different phases of the COVID-19 pandemic. The results showed that in the early phase, patients had more risk factors, higher smoking rates, more severe stroke severity, and higher level of disability. However, in the late phase, only the incidence of ischemic stroke increased.

Balance deficit is the domain of the Fugl-Meyer scale that best explain limitations in functional independence during hospitalization after a stroke

Kenia Kiefer Parreiras de Menezes, Aline Alvim Scianni, Patrick Roberto Avelino, Iza de Faria-Fortini, Luci Fuscaldi Teixeira-Salmela, Christina Danielli Coelho de Morais Faria

Summary: This study aimed to investigate which residual sensorimotor impairments would best explain functional independence during hospitalization after a stroke. The results showed that balance was the most important factor in explaining functional independence, while sensory function and upper limb motor function also contributed to the explained variance.
