Background: Despite the many tools available to modern medicine, predicting the neurological and functional status of patients after severe brain injury remains difficult.

Aim: This analysis evaluates the outcomes of patients with the most severe degree of cerebral function impairment.

Design: Retrospective cohort study.

Setting: Patients hospitalized in the long-term Intensive Care Unit (ICU) department in the Military University Hospital in Prague between 2015-2022.

Population: We analyzed patients with severe acquired brain damage from five distinct etiologies whose initial Glasgow Coma Scale (GCS) score was eight or less upon admission to ICU due to neurological damage.

Methods: Several parameters reflecting the patients' clinical status were evaluated. Overall survival after discharge from the ICU was calculated according to the Kaplan-Meier model with comparison between traumatic (TR) and non-traumatic (non-TR) etiologies.

Results: The analyzed cohort of 221 patients consisted of 116 patients of TR and 105 of non-TR etiology. There was no significant difference in overall survival between TR and non-TR groups. The length of hospitalization in the ICU was similar in both groups with a median of 94 days. The majority of patients had an improvement of GCS during the hospitalization with a median improvement of five points. GCS improvement occurred in the vast majority of patients regardless of TR or non-TR etiology.

Conclusions: We did not observe a statistically significant difference in mortality or log-term neurological status between patients with severe brain injury of traumatic or non-traumatic etiology for the duration of our follow-up. The majority of patients had improved GCS, were successfully decannulated, but remained disabled with severe limitations of functional independence.

Clinical rehabilitation impact: The return of the patient to normal life is a rehabilitation challenge, regardless of the etiology of brain injury, and is extremely influenced by the level of development of neurorehabilitation programs in individual institutions, the severity of brain injury, and the individual motivation of the patient.

Background: Reduced longitudinal median nerve gliding is a new promising diagnostic feature in carpal tunnel syndrome (CTS). However, the complexity of existing ultrasound analysis protocols undermines the application in routine clinical practice.

Aim: To provide a simple method for assessing longitudinal gliding with ultrasound, without the need for post-hoc image analysis.

Design: 1) Retrospective cohort study, validation by external blinded reviewers; 2) proof of concept in body donors.

Setting: 1) Outpatient clinic; 2) anatomy department.

Population: The population included 48 patients with idiopathic CTS diagnosed by electrodiagnostic testing and ultrasound, as well as 15 healthy controls. Twelve, non-frozen, non-embalmed body donors were enrolled.

Methods: Longitudinal gliding of the median nerve in the carpal tunnel was visualized in all patients with idiopathic CTS and healthy controls. All ultrasound videos were pseudonymized, equipped with a scale, and randomized. Videos were analyzed by four independent radiologists, all blinded to clinical characteristics. The endpoint was gliding rated as millimeters. Validity of the technique was tested by using speckle tracking software, and in body donors, directly measuring nerve excursion in situ, simultaneously to ultrasound.

Results: Gliding differed significantly between controls and patients with CTS, decreasing with incremental CTS severity. A cut-off value of 3.5 mm to identify patients with CTS, yielded 93.8% sensitivity and 93.3% specificity. Intraclass correlation coefficient among senior author and raters was 0.798 (95% CI 0.513 to 0.900, P<0.001), indicating good reliability. Speckle tracking and especially direct validation in body donors correlated well with ultrasound findings.

Conclusions: First, longitudinal median nerve gliding can reliably be assessed using this simple technique without the need for complicated procedures. Second, a decrease in gliding was found with progressive severity of CTS. Reproducibility for measured distances is good among raters.

Clinical rehabilitation impact: An easy to apply sonography parameter would bolster the diagnostic ability of specialists in physical medicine and rehabilitation in daily routine.

Background: The factor structure of the Tampa Scale of Kinesiophobia Heart version has rarely been adequately analyzed. We aimed to evaluate the psychometric properties of this scale through a variety of exploratory and confirmatory factorial approaches.

Aim: To perform a translation, cross-cultural adaptation, and psychometric evaluation of the Spanish version of the Tampa Scale of Kinesiophobia Heart in patients attending Cardiac Rehabilitation (TSK-SPA).

Design: Cross-sectional study.

Setting: A Cardiac Rehabilitation unit.

Population: Adults with the principal diagnosis of coronary artery disease (83%) who were referred to Cardiac Rehabilitation (N.=194; mean age, 64.28±9.2; 15% women).

Methods: We performed a translation and a cross-cultural adaptation of the TSK-SPA. The psychometric properties of validity comprising the face, content, and construct validity were then tested. Five factorial models were proposed to analyze the data structure. We examined the validity evidence of the TSK-SPA based on the relationships with other analyzed variables using the SF12 quality of life Questionnaire, the International Physical Activity Questionnaire, the Hospital Anxiety and Depression Scale and the Beck Depression Inventory. The reliability tests included internal consistency and stability over time.

Results: The results suggested a four-dimensional structure. Models with more than 1 dimension exhibited undesirable factor loadings or inadequate fit indices. Based on these results, a short version of the scale with 13 items is proposed. In terms of reliability, the TSK-SPA Heart was found internally consistent (α=0.79) and stable over time (test-retest = 0.82). An Exploratory Structural Equation Modeling (ESEM) analysis provided an acceptable fit for a hypothesized 4-factor model with the inclusion of a method factor: the root mean squared error of approximation was <0.05 (RMSEA = 0.046), and the comparative fit indices were >0.95 or close (CFI=0.994, TLI=0.934). Significant positive correlations were observed between the TSK-SPA scores and the measures of anxiety and depression, with correlation coefficients ranging from 0.35 to 0.48.

Conclusions: A best-fitting model was identified, and the proposed 13-item TSK-SPA Heart showed sufficient evidence of validity and reliability for Spanish patients with cardiovascular disease. The scale's overall reliability is deemed acceptable, although the factor reliability could be further enhanced.

Clinical rehabilitation impact: Using this questionnaire on fear or avoidance of movement will improve our understanding of cognitive-behavioral factors in patients with cardiovascular disease, aiding their rehabilitation and optimizing their prognosis.

Introduction: Pediatric physical therapists commonly treat children with postural control deficits. Ideally, pediatric functional postural control tests should therefore be able to identify postural control deficits in children with various disorders. Despite a plethora of available tests, evidence for their validity - especially known-groups - remains scarce. This review aims to determine the known-group validity of available functional postural control tests to differentiate various pediatric pathological groups of different ages from their typically developing (TD) peers.

Evidence acquisition: PubMed, Web of Science and Scopus were systematically searched (last update: February 2023; PROSPERO: CRD42023408982). Forty case-control studies with a pathological pediatric sample (N.=1331) and TD peers (N.=1889) were included and selected for data-extraction and -analysis. Risk of bias was assessed using the SIGN checklist and level of evidence was scored using GRADE. Random-effect meta-analyses were performed to estimate pooled standardized mean differences (SMD) for the various test types and subclassified based on pathology and/or age.

Evidence synthesis: When compared with TD peers, children with underlying pathologies performed significantly worse on pediatric functional postural control test batteries (SMD=-2.21), the Timed Up and Go Test and variants (SMD=2.30), the One Leg Stance test and variants (SMD=-2.14), while the Reach tests showed a smaller difference (SMD=-1.19). Subclassification within the meta-analyses showed that pathology was an influencing factor for the test batteries and the one leg stance test and variants. Age was an influencing factor for the reach tests. None of the included functional postural control tests exceeded a low level of evidence.

Conclusions: Pediatric functional postural control tests that assess multiple aspects of postural control (such as test batteries) seem to offer higher known-groups validity than single-task tests (e.g. reach tests). The underlying pathology has a larger impact on the validity of these tests than age. There remains an overall low level of evidence for the known-groups validity of pediatric functional postural control tests indicating the need for research with more homogenous groups and norm reference data.

Background: Around 40% of stroke survivor develop spasticity. Plantar flexors (PF) muscles are often affected, with severe functional impairment. The treatment of choice is botulinum toxin type A (BoNT-A) combined with adjuvant treatments. The temporary pharmacological effect implies periodic reassessment and reinjection. These long-term chronic programs require monitoring the functional impact of each cycle and the clinical evolution in relation to aging and repeated interventions.

Aim: Evaluating changes of functional level in patients with post-stroke spasticity treated with BoNT-A by assessing the long-term maintenance of the therapeutic efficacy.

Design: Retrospective longitudinal observational study.

Setting: Outpatients.

Population: Chronic stroke survivors undergoing BoNT-A treatment and subsequent intensive rehabilitation (10 sessions in a day-hospital regime).

Methods: Medical records of the enrolled patients were consulted. The primary endpoint was the change in PF spasticity by at least 1 point on the Modified Ashworth Scale (MAS) at each cycle. Secondary endpoints were the assessment of possible trends in gait parameters (Six Minute Walking Test [6MWT]; Timed Up and Go [TUG], and 10 Meters Walking Test [10mWT]) pre- and post-injection and at each cycle.

Results: Thirty-six patients were enrolled. A reduction of at least one MAS point for PF was recorded after each cycle in all subjects. A time-dependent reduction in the proportion of patients reporting an improvement higher than the minimal clinically important difference (MCID) in 6MWT and 10mWT was observed. In the case of TUG, this data kept stable at all cycles. A one-point increase in the basal functional ambulation classification (FAC) score resulted in a reduction in the probability of having a TUG improvement greater than the MCID. The opposite correlation was found for 6MWT and 10mWT.

Conclusions: With the proposed treatment, the clinical significance TUG improvement remains constant throughout repeated cycles and the proportion of patients with improvement in 6MWT and 10mWT tends to decline over time. The predictive value of basal FAC on the functional variables expected improvement may provide a potential treatment targeting tool.

Clinical rehabilitation impact: These results may deliver prognostic indication allowing an optimized integration of different post-BoNT-A rehabilitation approaches, agreeing with current evidence. Adequate monitoring and treatment protocols are crucial for the stability of functional level and may prevent excessive fluctuations.

Background: The difficulties in obstacle walking are significant in people with Parkinson's disease (PD) leading to an increased fall risk. Effective interventions to improve obstacle walking with possible training-related neuroplasticity changes are needed. We developed two different exercise programs, complex walking training and motor-cognitive training, both challenging motor and cognitive function for people with PD to improve obstacle walking.

Aim: To investigate the effects of these two novel training programs on obstacle walking and brain activities in PD.

Design: A single-center randomized, single-blind controlled study.

Setting: University laboratory; outpatient.

Population: Individuals with idiopathic PD.

Methods: Thirty-two participants were randomly assigned to the complex walking training group (N.=11), motor-cognitive training group (N.=11) or control group (N.=10). Participants in training groups received exercises for 40 minutes/session, with a total of 12-session over 6 weeks. Control group did not receive additional training. Primary outcomes included obstacle walking, and brain activities (prefrontal cortex (PFC), premotor cortex (PMC), and supplementary motor area (SMA)) during obstacle walking by using functional near-infrared spectroscopy. Secondary outcomes included obstacle crossing, timed up and go test (TUG), cognitive function in different domains, and fall efficacy scale (FES-I).

Results: The motor-cognitive training group demonstrated greater improvements in obstacle walking speed and stride length, SMA activity, obstacle crossing velocity and stride length, digit span test, and TUG than the control group. The complex walking training did not show significant improvement in obstacle walking or change in brain activation compared with control group. However, the complex walking training resulted in greater improvements in Rey-Osterrieth Complex Figure test, TUG and FES-I compared with the control group.

Conclusions: Our 12-session of the cognitive-motor training improved obstacle walking performance with increased SMA activities in people with PD. However, the complex walking training did not lead such beneficial effects as the cognitive-motor training.

Clinical rehabilitation impact: The cognitive-motor training is suggested as an effective rehabilitation program to improve obstacle walking ability in individuals with PD.

Background: Exercise has been shown to reduce the rate of mild cognitive impairment (MCI) and Alzheimer's disease. Although motor coordination movements and poses in Ruesi Dadton (RD) exercises may improve cognitive function, RD is rarely used for MCI. To date, there is insufficient evidence on whether 12 weeks of RD exercise correlates with blood biomarkers related to neurogenesis and plasticity.

Aim: To determine the effects on blood biomarkers of 12-week RD in MCI.

Design: Two-group parallel randomized controlled trial.

Setting: Community exercise.

Population: Individual with MCI.

Methods: Fifty-eight participants (n.=29 in each group). The RD group performed 60min of RD exercises (15 poses) three times weekly for 12 weeks. The control group received no intervention. In addition, both groups were given information regarding MCI symptoms by the physician on the first day. Peripheral blood was collected to measure serum brain-derived neurotrophic factor (BDNF) and sirtuin 1 (SIRT1) levels before and after intervention.

Results: The effects of 12-week RD pre- and post-intervention were examined using 2×2 repeated multivariate analyses, which showed significant differences in interaction by group and time. Student's t-tests and paired t-tests were employed in subsequent analyses to evaluate between-group and within-group differences for both biomarkers.

Conclusions: In each test, we discovered increased levels of BDNF and SIRT1 in the RD group but not in the control group. These findings suggested that RD could benefit MCI patients through enhanced BDNF and SIRT1 levels.

Clinical rehabilitation impact: Twelve weeks of RD might be helpful to patients with MCI and older people who experience cognitive impairment by improving blood biomarkers responsible for brain plasticity and amyloid plaque degradation.
