Current guidelines recommend cardiac rehabilitation programs (CRP) as a means to improve functional status of patients after coronary revascularization. However, research supporting this recommendation has been limited and positive effects of CRP on diastolic function are controversial. The aim of this study was to examine the effects of an 8-week CRP on left ventricular diastolic function.This randomized, clinical trial included 29 men with ST elevation myocardial infarction (MI) who had received reperfusion therapy, i.e. coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). They were randomized to a training group (n = 15; mean age: 54.2 ± 9.04 years old) and a control group (n = 14; mean age: 51.71 ± 6.98 years old). Patients in the training group performed an 8-week CRP with an intensity of 60-85% of maximum heart rate. Exercise sessions lasted 60-90 minutes and were held three times a week. At the start and end of the study, all patients performed symptom-limited exercise test based on Naughton treadmill protocol. Pulsed-wave Doppler echocardiography was also used to determine peak velocity of early (E) and late (A) waves, E/A ratios, and the deceleration time of E (DT).Left ventricular diastolic indices (E, A, E/A ratio, DT) did not change significantly after the CRP. Compared to baseline, patients in the training group had significant improvements in functional capacity (8.30 ± 1.30 vs. 9.7 ± 1.7) and maximum heart rate (118.50 ± 24.48 vs. 126.85 ± 22.75). Moreover, resting heart rate of the training group was significantly better than the control group at the end of the study (75.36 ± 7.94 vs. 79.80 ± 7.67; P < 0.001).An 8-week CRP in post-MI patients revascularized with PCI or CABG led to improved exercise capacity. However, the CRP failed to enhance diastolic function. HubMed – rehab

Purpose Concerns that disability benefits may create disincentives for employment may be especially relevant for young American military veterans, particularly veterans of the recent wars in Iraq and Afghanistan who are facing a current economic recession and turning in large numbers to the Department of Veterans Affairs (VA) for disability compensation. This study describes the rate of employment and VA disability compensation among a nationally representative sample of veterans under the age of 65 and examines the association between levels of VA disability compensation and employment, adjusting for sociodemographics and health status. Methods Data on a total of 4,787 veterans from the 2010 National Survey of Veterans were analyzed using multinomial logistic regressions to compare employed veterans with two groups that were not employed. Results Two-thirds of veterans under the age of 65 were employed, although only 36 % of veterans with a VA service-connected disability rating of 50 % or higher were employed. Veterans who received no VA disability compensation or who were service-connected 50 % or more were more likely to be unemployed and not looking for employment than veterans who were not service-connected or were service-connected less than 50 %, suggesting high but not all levels of VA disability compensation create disincentives for employment. Results were similar when analyses were limited to veterans who served in Iraq and Afghanistan. Conclusions Education and vocational rehabilitation interventions, as well as economic work incentives, may be needed to maximize employment among veterans with disabilities.

OBJECTIVE: To estimate the frequency of people with leprosy-related physical disabilities after release from multidrug treatment and to analyze their spatial distribution. METHODS: Descriptive cross-sectional study with 232 leprosy patients treated between 1998 and 2006. Physical disabilities were assessed using the World Health Organization disability grading and the eye-hand-foot (EHF) sum score. The residential address of patients and rehabilitation centers were geocoded. It was estimated the overall frequency of physical disability and frequency by disability grade (grade 0, grade 1, and grade 2) according to the WHO disability grading taking into consideration clinical and sociodemographic variables in the descriptive analysis. Student’s t-test, chi-square test (?2), and Fisher’s test were used as appropriate at a 5% significance level. RESULTS: Of the patients studied, 51.6% were female, mean age 54 years old (SD 15.7), 30.5% had less than 2 years of formal education, 43.5% were employed, and 26.9% were retired. Borderline leprosy was the most prevalent form of leprosy (39.9%). A total of 32% of these patients had disabilities according to the WHO disability grading and the EHF score. Disabilities increased with age (p = 0.029), they were more common in patients with multibacillary leprosy (p = 0.005) and poor self-rated physical health (p < 0.001). Those who required prevention/rehabilitation care traveled on average 5.5 km to the rehabilitation center. People with physical disabilities lived scattered across the city but they were mostly concentrated in the most densely populated and socioeconomically deprived area. CONCLUSIONS: There is a high frequency of people with leprosy-related disabilities after release from multidrug therapy. Prevention and rehabilitation actions should target uneducated and older patients, those who had multibacillary forms of leprosy and poor self-rated physical health. The travel distance to rehabilitation centers calls for reorganization of local care networks. HubMed – rehab
Contralesional motor deficits after unilateral stroke reflect hemisphere-specific control mechanisms.

We have proposed a model of motor lateralization, in which the left and right hemispheres are specialized for different aspects of motor control: the left hemisphere for predicting and accounting for limb dynamics and the right hemisphere for stabilizing limb position through impedance control mechanisms. Our previous studies, demonstrating different motor deficits in the ipsilesional arm of stroke patients with left or right hemisphere damage, provided a critical test of our model. However, motor deficits after stroke are most prominent on the contralesional side. Post-stroke rehabilitation has also, naturally, focused on improving contralesional arm impairment and function. Understanding whether contralesional motor deficits differ depending on the hemisphere of damage is, therefore, of vital importance for assessing the impact of brain damage on function and also for designing rehabilitation interventions specific to laterality of damage. We, therefore, asked whether motor deficits in the contralesional arm of unilateral stroke patients reflect hemisphere-dependent control mechanisms. Because our model of lateralization predicts that contralesional deficits will differ depending on the hemisphere of damage, this study also served as an essential assessment of our model. Stroke patients with mild to moderate hemiparesis in either the left or right arm because of contralateral stroke and healthy control subjects performed targeted multi-joint reaching movements in different directions. As predicted, our results indicated a double dissociation; although left hemisphere damage was associated with greater errors in trajectory curvature and movement direction, errors in movement extent were greatest after right hemisphere damage. Thus, our results provide the first demonstration of hemisphere specific motor control deficits in the contralesional arm of stroke patients. Our results also suggest that it is critical to consider the differential deficits induced by right or left hemisphere lesions to enhance post-stroke rehabilitation interventions.
