RESUMEN
BACKGROUND: This study aimed to clarify the effects of exercise-based cardiac rehabilitation (CR) on patients with heart failure.MethodsâandâResults: Patients were divided into groups according to intervention duration (<6 and ≥6 months). We searched for studies published up to July 2023 in Embase, MEDLINE, PubMed, and the Cochrane Library, without limitations on data, language, or publication status. We included randomized controlled trials comparing the efficacy of CR and usual care on mortality, prehospitalization, peak oxygen uptake (VÌO2), and quality of life. Seventy-two studies involving 8,495 patients were included in this review. It was found that CR reduced the risk of rehospitalization for any cause (risk ratio [RR] 0.80; 95% confidence interval [CI] 0.70-0.92) and for heart failure (RR 0.88; 95% CI 0.78-1.00). Furthermore, CR was found to improve exercise tolerance (measured by peak VÌO2and the 6-min walk test) and quality of life. A subanalysis performed based on intervention duration (<6 and ≥6 months) revealed a similar trend. CONCLUSIONS: Our meta-analysis showed that although CR does not reduce mortality, it is effective in reducing rehospitalization rates and improving exercise tolerance and quality of life, regardless of the intervention duration.
RESUMEN
Circulatory power (CP) and ventilatory power (VP), obtained by cardiopulmonary exercise testing (CPX), have been suggested to be excellent prognostic markers for heart failure. However, the normal values of these parameters in healthy Japanese populations remain unknown; thus, we aimed to investigate these values in such a population. A total of 391 healthy Japanese participants, 20-78 years of age, underwent CPX with a cycle ergometer with ramp protocols. Systolic blood pressure (SBP), heart rate, oxygen uptake ([Formula: see text]O2) at peak exercise, and the slope of minute ventilation ([Formula: see text]E) versus carbon dioxide ([Formula: see text]CO2) ([Formula: see text]E vs. [Formula: see text]CO2 slope) were measured. CP was calculated by multiplying the peak [Formula: see text]O2 and SBP values, and VP was calculated by dividing the peak SBP value by the [Formula: see text]E versus [Formula: see text]CO2 slope. For males and females, the average CP values were 6119 ± 1280 (mean ± standard deviation) and 4775 ± 914 mmHg·mL/min/kg, respectively (p < 0.001). The average VP values for males and females were 8.0 ± 1.3 and 6.9 ± 1.3 mmHg (p < 0.001). CP decreased with age in both sexes. VP increased with age in females, with no significant change in males. We calculated the normal values for CP and VP in a healthy Japanese population. The results can contribute to the evaluation of patients' CPX results as a reference.

[Purpose] Walking ability should be predicted as early as possible in acute stroke patients. The purpose is to construct a prediction model for independent walking from bedside assessments using classification and regression tree analysis. [Participants and Methods] We conducted a multicenter case-control study with 240 stroke patients. Survey items included age, gender, injured hemisphere, the National Institute of Health Stroke Scale, the Brunnstrom Recovery Stage for lower extremities, and "turn over from a supine position" from the Ability for Basic Movement Scale. The National Institute of Health Stroke Scale items, such as language, extinction, and inattention, were grouped under higher brain dysfunction. We used the Functional Ambulation Categories to classify patients into independent (four or more the Functional Ambulation Categories; n=120) and dependent (three or fewer the Functional Ambulation Categories; n=120) walking groups. A classification and regression tree analysis was used to create a model to predict independent walking. [Results] The Brunnstrom Recovery Stage for lower extremities, "turn over from a supine position" from the Ability for Basic Movement Scale, and higher brain dysfunction were the splitting criteria for classifying patients into four categories: Category 1 (0%), severe motor paresis; Category 2 (10.0%), mild motor paresis and could not turn over; Category 3 (52.5%), with mild motor paresis, could turn over, and had higher brain dysfunction; and Category 4 (82.5%), with mild motor paresis, could turn over, and no higher brain dysfunction. [Conclusion] We constructed a useful prediction model for independent walking based on the three criteria.
RESUMEN
The therapy for unilateral spatial neglect (USN) is unclear. This case report investigated the effect of standing and walking training using a laser pointer based on stimulus-driven attention for USN. The patient was a right-handed 79-year-old man with cardiogenic cerebral embolism in the right middle and posterior cerebral arteries. Initially, we evaluated the absence of hemiparalysis in the lower limb and sensory disorder; almost all daily activities were performed independently. Intervention effects were verified using the BABA method. The course of the four phases (B1, A1, B2, A2) was conducted for 5 days. In the B1 and B2 phases, standing and walking training using a laser pointer was performed additionally to conventional physical therapy. Outcomes were measured using the Behavioural Inattention Test conventional subtest (BIT-c), Catherine Bergego Scale (CBS), and modified Posner task (MPT). The BIT-c remained unchanged in each phase. CBS scores improved after B1 and B2. In the MPT, the reaction time in the left space reduced after B1 and B2 compared with those in the A1 and A2 control phases. In this case, training may have contributed to the improvement in the response to the neglected space and behavioural assessment of USN.

Transcatheter atrial septal defect (ASD) closures using an Amplatzer Septal Occluder (ASO) have been widely performed. Compared to children, we sometimes experience late recovery of exercise performance in adult patients. Our study aimed to evaluate the change in the cardiopulmonary exercise capacity in asymptomatic or mildly symptomatic adult patients after a transcatheter ASD closure using an ASO. The subjects consisted of 29 patients (age 39.5 ± 13.6 years) that underwent cardiopulmonary exercise testing (CPX) before, 3, 6, and 12 months after a transcatheter secundum ASD closure using an ASO. The peak oxygen consumption (peak VO2), anaerobic threshold (AT), and slope of the correlation between the ventilation and carbon dioxide production (VE/VCO2 slope) were evaluated. We also evaluated the left-ventricular end-diastolic diameter (LVEDD), right-ventricular end-diastolic dimension (RVEDD) by echocardiography, and hemodynamic values by cardiac catheterization before the ASO procedure. The peak VO2 did not show any improvement 3 months after the ASO procedure; however, a significant improvement was displayed 6 and 12 months (baseline: 23.4 ± 6.3, 3 months: 23.6 ± 6.4, 6 months: 25.1 ± 5.6, 12 months: 26.4 ± 5.3 mL/kg/min; p < 0.001) after the ASO. The LVEDD (before: 38.1 ± 3.6, 3 months: 43.4 ± 3.4 mm; p < 0.001) and RVEDD (before: 33.6 ± 5.3, 3 months: 26.3 ± 2.6 mm; p < 0.001) on echocardiography quickly improved 3 months after the ASO. Although the LVEDD and RVEDD normalized 3 months after the ASO, the peak VO2 still decreased; however, the peak VO2 improved to almost a normal range 6 months after the ASO.

OBJECTIVES: To investigate the intensity and effectiveness of rehabilitation in acute stroke patients according to the severity of functional impairments in them. MATERIALS AND METHODS: This retrospective cohort study included 294 patients with acute hemispheric stroke admitted to three acute-care hospitals who subsequently underwent an inpatient rehabilitation program. Stroke severity was classified according to neurological deficits and trunk dysfunction. The following data were obtained from medical records: age, sex, stroke type, lesion side, hospitalization duration, initial functional status determined using the National Institutes of Health Stroke Scale, rehabilitation start date, first day out of bed after admission, total treatment duration, total number of treatment sessions, rehabilitation implementation rate between start of rehabilitation and discharge, trunk control test and Barthel Index score on the first day out of bed after admission and discharge, and post-discharge outcomes. Hierarchical cluster analysis was performed with clusters categorized using the National Institutes of Health Stroke Scale and trunk control test scores. Variables were compared using the Kruskal-Wallis test, and Dunn's nonparametric comparison test was performed for post-hoc analysis to determine differences between clusters. RESULTS: The National Institutes of Health Stroke Scale and trunk control test showed a significant correlation (r = -0.816, p < 0.01) using which cluster analysis identified three clusters. Rehabilitation showed a ceiling effect in patients with mild stroke and a floor effect in patients with severe stroke. CONCLUSION: These results may guide the determination of rehabilitation intensity with reference to the severity of neurological deficits and trunk dysfunction.

OBJECTIVES: Sitting ability during the acute phase after stroke is a useful indicator of functional outcomes; however, factors that affect this ability have not been evaluated. Therefore, this study aimed to identify and evaluate factors that affect sitting ability in the acute phase after stroke. MATERIALS AND METHODS: This multicenter prospective cohort study included hemispheric stroke patients who underwent an inpatient rehabilitation program after acute stroke from five acute care hospitals. The effect of age, sex, lesion side, etiology, consciousness disorder, stroke and dementia history, stroke-related complications, National Institutes of Health Stroke Scale score, hemiparalysis, turn-over movement from the supine position and sit-up movement, and Scale for Contraversive Pushing on the "remain sitting" item in the revised version of the Ability of Basic Movement Scale at the time of acute hospital discharge were investigated. Factors affecting sitting ability were identified using binomial logistic regression analysis. RESULTS: We included 293 stroke patients. Age (odds ratio: 0.943, 95% confidence interval: 0.910-0.977, p=0.001), National Institutes of Health Stroke Scale score (odds ratio: 0.862, 95% confidence interval: 0.811-0.916, p<0.001), and Scale for Contraversive Pushing score (odds ratio: 0.543, 95% confidence interval: 0.419-0.705, p<0.001) were identified as independent predictors of sitting ability at the time of hospital discharge (median; 23.0 days). CONCLUSIONS: Older patients and those with high Scale for Contraversive Pushing and National Institutes of Health Stroke Scale scores experienced difficulties in regaining sitting ability. These results may guide physical therapy for patients with impaired sitting ability due to hemispheric stroke.

Pusher behavior (PB) is a severe lateral postural disorder that involves a disturbed subjective postural vertical (SPV) in the frontal plane. SPV is measured by determining the mean value and standard deviation of several trials beginning on both the contralesional- and ipsilesional-tilted positions. However, the postural representation, when passively tilted to the contralesional versus ipsilesional position, is different between patients with and without PB. Therefore, we hypothesized that SPV dependence on the starting position will be influenced by PB. For 53 patients with hemispheric stroke enrolled, SPV was measured using a non-motorized vertical board with eyes closed. The mean value (tilt direction) and standard deviation (variability) were calculated in four trials, each from two positions, with the patient tilted to the contralesional position (SPV-CL condition) and then to the ipsilesional position (SPV-IL condition). Patients were categorized into the non-pusher (n = 29) and pusher (n = 24) groups. In the SPV-CL trials, the tilt direction was significantly tilted contralesionally for the pusher group (- 6.3° ± 1.6°) compared with that for the non-pusher group (- 2.2° ± 1.8°; p < 0.001), with no significant difference in variability between the groups. In the SPV-IL trials, the tilt direction was not significantly different between the groups, but the variability was significantly higher in the pusher group (4.8° ± 2.0°) than in the non-pusher group (2.2° ± 1.3°; p < 0.001). The dependence of tilt direction and variability of SPV on the starting position in patients with PB differed from those noted in patients without PB. These results may help explain this abnormal posture and optimize neurological rehabilitation strategies for PB.

BACKGROUND: There is little evidence regarding the effect of outpatient cardiac rehabilitation (CR) on exercise capacity or the long-term prognosis in patients after coronary artery bypass graft surgery (CABG). This study aimed to determine whether participation in outpatient CR improves exercise capacity and long-term prognosis in post-CABG Japanese patients in a multicenter cohort.MethodsâandâResults:We enrolled 346 post-CABG patients who underwent cardiopulmonary exercise testing during early (2-3 weeks) and late (3-6 months) time points after surgery. They formed the Active (n=240) and Non-Active (n=106) CR participation groups and were followed for 3.5 years. Primary endpoint was a major adverse cardiac event (MACE): all-cause death or rehospitalization for acute myocardial infarction/unstable angina/worsening heart failure. Peak oxygen uptake at 3-5 months from baseline was significantly more increased in Active than in Non-Active patients (+26±24% vs. +19±20%, respectively; P<0.05), and the MACE rate was significantly lower in Active than Non-Active patients (3.4% vs. 10.5%, respectively; P=0.02). Multivariate Cox proportional hazard analysis showed that participation in outpatient CR was a significant prognostic determinant of MACE (P=0.03). CONCLUSIONS: This unique study showed that a multicenter cohort of patients who underwent CABG and actively participated in outpatient CR exhibited greater improvement in exercise capacity and better survival without cardiovascular events than their counterparts who did not participate.

[Purpose] To determine age-related differences in the subjective vertical in the frontal plane in healthy adults. [Subjects and Methods] The subjects were 26 healthy adults. For the subjective visual vertical (SVV), subjects were presented with a visual indicator in front of them that was rotated. For the subjective postural vertical-eyes open (SPV-EO) and subjective postural vertical (SPV), subjects sat in a seating device that was tilted right or left. The subjects gave a signal when they perceived true verticality. Each task was performed eight times. The items examined were the mean (tilt direction) and standard deviation (variability) of the eight trials, then the mean of four trials that started from the right or left side position. These items were compared between the young (age: 22-30 years [range]) and elderly (age: 60-74 years) groups. [Results] As for variability, the elderly group demonstrated significantly higher values of SPV-EO and SPV. As for the starting point effect, the elderly group demonstrated greater bias toward the starting direction than did the young group in SPV-EO and SPV in frontal plane. [Conclusion] The postural vertical was shown to change with age. Consideration of age-related changes and the starting point effect was indicated to be important.
RESUMEN
[Purpose] The relationship between white matter lesions (WMLs) and pushing behavior (PB) is still poorly understood. The purpose of this study was to investigate whether damage from WMLs affects the functional outcome of PB after acute stroke. [Subjects and Methods] In total, 37 patients were included. PB was assessed using the standardized Scale for Contraversive Pushing (SCP). Stroke types were classified as total anterior circulation infarct (TACI), partial anterior circulation infarct (PACI), or lacunar syndrome using the Bamford classification. WML severity was categorized into four groups using the Fazekas visual scale. Thereafter, patients were divided into 4 groups according to the stroke type and/or presence of WMLs. The SCP, Trunk Control Test (TCT), Stroke Impairment Assessment Set (SIAS), and Barthel Index were the outcome measures. [Results] The SCP and TCT in patients with PACI without WMLs were better than those in patients with TACI with or without WMLs. Regarding SCP, TCT, and SIAS, patients with TACI had poorer values compared with PACI, regardless of WML severity. Barthel Index efficiency was not significantly different between the groups. [Conclusion] Our results suggest that moderate to severe WMLs and PACI had a relationship with PB severity and truncal balance.
RESUMEN
BACKGROUND: Trunk performance and sitting balance, especially lateral sitting control, are important predictors of functional outcome after stroke. However, no studies have focused only on trunk function in the frontal plane for persons with acute-phase stroke. OBJECTIVE: To investigate the effects of lateral sitting training on a tilting platform in persons with stroke. METHODS: An assessor-blinded, randomized, controlled trial was carried out involving inpatients at a stroke rehabilitation center. Patients were allocated to either an experimental group (n = 15) or a control group (n = 15). The experimental group sat without leg support on a platform tilted 10° to the paretic side in the frontal plane, while the controls sat on a horizontal platform. Both groups were asked to move their trunk laterally from the paretic side to the nonparetic side. In addition to conventional therapy, this training was performed 60 times/session, with 6 sessions/week. Trunk function was assessed using the Trunk Control Test (TCT), and the ability to move the trunk laterally was evaluated kinematically. Measurements were performed at baseline and after training. Two-way repeated measures analysis of variance was used to test the significance between and within treatments for each dependent variable. RESULTS: None of the demographic data differed between the groups. After training, a significant improvement was noted in the experimental group compared to the controls in the TCT and the ability for lateral trunk transference (P < 0.05, 1 - ß = 0.98, effect size = 0.4). CONCLUSION: Lateral sitting training on the tilting platform improved the impaired trunk function of persons with stroke.

[Purpose] Pushing behavior is classically described as a disorder of body orientation in the coronal plane. Most interventions for pushing behavior have focused on correcting the deviation in vertical perception. However, pushing behavior seems to involve erroneous movements associated with excessive motor output by the non-paretic limbs and trunk. The present study aimed to inhibit muscular hyper-activity by placing the non-paretic limbs and trunk in the prone position. [Subjects and Methods] The subjects of the present study were 3 acute stroke patients with severe pushing behavior. The study consisted of the following 3 phases: baseline, intervention, and follow-up. In addition to conventional therapy, patients received relaxation therapy in the prone position for 10 minutes a day over 2 days. The severity of pushing behavior was assessed using the scale for contraversive pushing, and truncal balance was evaluated using the trunk control test. These assessments were performed before and after the baseline phase, and after the intervention and follow-up phases. [Results] At the baseline phase, both scores were poor. Both scores improved after the intervention and follow-up phases, and all the patients could sit independently. [Conclusion] Relaxation therapy in the prone position might ameliorate pushing behavior and impaired truncal balance.
RESUMEN
BACKGROUND: The safety of exercise-based cardiac rehabilitation (CR) has not been investigated in Japan, so a nationwide survey was conducted to investigate the incidence of adverse events (AEs) associated with CR and exercise testing. METHODS AND RESULTS: In total, 136 hospitals reported operating recovery-phase CR programs, amounting to 383,096 patient-hours of exercise training. The incidence rates of all AEs and life-threatening AEs (LAE: death, cardiac arrest, acute myocardial infarction, cardiac rupture) during exercise sessions were 12 and 1 event/383,096 patient-hours (3.13 and 0.26 events/100,000patient-hours), respectively. When CR programs were categorized as "Formal" in which an exercise prescription based on exercise testing was issued to individual patients or "Non-formal" without exercise prescription, the incidence of AEs during and within the 24 h after an exercise session was significantly lower in the Formal than the Non-formal CR programs (P<0.001), despite similar hospital size and coronary intervention volumes between the 2 category hospitals. Moreover, LAEs did not occur in 277,721 patient-hours in Formal CR, whereas 2 LAEs occurred in 105,375 patient-hours in Non-formal CR (P<0.05). During 469,215 exercise testing sessions, 3 LAEs (0.64 event/100,000tests) and 31 non-LAEs (6.61 events/100,000tests) occurred. CONCLUSIONS: This first nationwide survey in Japan revealed that both exercise-based CR and exercise testing are generally safe, and that Formal CR, in which an individual exercise prescription is determined by exercise testing, is particularly safe.

PURPOSE: This study assessed the characteristics, management, and outcomes of dysphagia rehabilitation in older patients with CVD in a super-aged society, highlighting the need for comprehensive management strategies in community hospital settings. It aimed to uncover valuable insights into the benefits of integrating dysphagia rehabilitation with cardiac care in patient management. METHODS: We conducted a retrospective review of patients with CVD aged ≥ 65 years who were admitted to Niigata Minami Hospital between January 2019 and December 2021. We focused on patients requiring dysphagia rehabilitation and assessing the effects of these interventions on recovery. RESULTS: The study included 732 participants with an average age of 86.0 ± 7.8 years, of whom 41.9% were male. Approximately 55.1% required dysphagia rehabilitation. Dysphagia rehabilitation significantly improved oral caloric intake and BMI in patients who underwent rehabilitation, and these improvements were comparable to those in patients who did not require dysphagia rehabilitation. Significant enhancement in the ADL of patients was observed at discharge. Patients who required dysphagia rehabilitation also had longer hospital stays and were more likely to be discharged to nursing facilities. CONCLUSION: Dysphagia is common in older patients with CVD, and dysphagia rehabilitation positively affects the maintenance of nutritional status and helps patients achieve ADL independence at discharge. This study highlights the importance of integrating dysphagia rehabilitation into ordinary cardiac rehabilitation programs for older patients with CVD to improve their QOL.
