In addition to a beneficial effect on exercise tolerance and an associated reduction of global cardiovascular risk, modificationof physical activity has a positive effect on the quality of life, reducing, among other things, the severity of erectile dysfunction (ED).The specific nature of sexual activity, which combines the need to maintain appropriate exercise tolerance and good erection quality, prompted us to evaluate the association between exercise tolerance and severity of ED in an intervention group of subjectswith ischaemic heart disease (IHD) and ED in the context of cardiac rehabilitation (CR).A total of 138 men treated invasively for IHD (including 99 treated with percutaneous coronary intervention and 39 treatedwith coronary artery bypass grafting) who scored 21 or less in the initial IIEF-5 test were investigated. Subjects were randomised intotwo groups. The study group included 103 subjects (mean age 62.07 ± 8.59 years) who were subjected to a CR cycle. The controlgroup included 35 subjects (mean age 61.43 ± 8.81 years) who were not subjected to any CR. All subjects filled out an initialand final IIEF-5 questionnaire and were evaluated twice with a treadmill exercise test. The CR cycle was carried out for a periodof 6 months and included interval endurance training on a cycle ergometer (three times a week) and general fitness exercises andresistance training (twice a week).The CR cycle in the study group resulted in a statistically significant increase in exercise tolerance (7.15 ± 1.69 vs. 9.16 ± 1.84 METs,p < 0.05) and an increase in erection quality (12.51 ± 5.98 vs. 14.39 ± 6.82, p < 0.05) which was not observed in the controlgroup. A significant effect of age on a progressive decrease in exercise tolerance and erection quality was found in the study group. Exercise tolerance and erection quality were also negatively affected by hypertension and smoking. A significant correlation between exercise tolerance and erection quality prior to the rehabilitation cycle indicates better erection quality in patients with better effort tolerance. The improvement in exercise tolerance did not correlate significantly with initial exercise tolerance or age of the subjects. Incontrast, a significantly higher increase in erection quality was observed in younger subjects with the lowest baseline severity of ED.The relative increase in exercise tolerance in the group subjected to CR was significantly higher than the relative increase in erection quality but these two effects were not significantly correlated with each other.1. In subjects with IHD and ED, erection quality is significantly correlated with exercise tolerance. 2. Exercise traininghad a positive effect on both exercise tolerance and erection quality but the size of these two effects was different and they ran independently of each other. HubMed – rehab

A shift in the dynamic autonomic nervous system (ANS) balance towards sympathetic activity in patients with acute myocardial infarction (AMI) predisposes them to life-threatening ventricular arrhythmias. Improvement of unfavourable changes in ANS can be expected in such patients as a result of physical training. A beneficial shift in ANS balance towardsparasympathetic activity could be confirmed by demonstrating increased baroreceptor reflex sensitivity (BRS) as well as favourablechanges in heart rate variability (HRV) parameters.To analyse the effect of different forms of physical training on ANS activity in patients with AMI after hospital discharge.The study included 38 patients with AMI (aged 59 ± 8 years) subjected to 2-month exercise training. Group 1 (n = 19)underwent 3-week supervised in-hospital cardiac rehabilitation followed by 5-week home-based training, and Group 2 (n = 19) underwent 8-week home-based training. BRS and HRV were determined based on a 10-min recording of systolic arterial pressureand the cardiac cycle. Measurements were performed one day before discharge (R1) and after 2 months of training (R2).A significant increase in the mean values of TP (total power), HF (high frequency power), rMSSD (square root of themean of the squared differences between successive R-R intervals), and pNN50 (proportion of differences between successive R-R intervals that are greater than 50 ms) was observed in the overall study group, along with trends for higher SDNN (standarddeviation of the mean of sinus rhythm R-R intervals) and HFnu (normalised HF power), and for lower LFnu (normalised LF power). Additionally, a significant increase in BRS (from 2.2 ± 0.6 to 5.1 ± 2.2 ms/mm Hg, p = 0.01) was found in patientswith baseline BRS ? 3 ms/mm Hg. A significant increase in rMSSD, pNN50, HF and HFnu, as well as a decrease in LFnu andLF/HF (LF to HF ratio) was observed in Group 1. In contrast, a significant increase in BRS was noted in Group 2.Various forms of 2-month physical training led to a favourable shift in autonomic balance towards parasympatheticactivity. Our findings suggest a clinically important effect of physical activity in patients after AMI. HubMed – rehab

To investigate the reliability and validity of video clips in assessing movement disorders in preschool children.The study group included 27 children with neuromotor concerns. The explorative validity group included children with motor problems (n = 21) or with typical development (n = 9). Hempel screening was used for live observation of the child, full recording, and short video clips. The explorative study tested the validity of the clinical classifications “typical” or “suspect.”Agreement between live observation and the full recording was almost perfect; Agreement for the clinical classification “typical” or “suspect” was substantial. Agreement between the full recording and short video clips was substantial to moderate. The explorative validity study, based on short video clips and the presence of a neuromotor developmental disorder, showed substantial agreement.Hempel screening enables reliable and valid observation of video clips, but further research is necessary to demonstrate the predictive value.

To investigate the effectiveness of a novel dynamic standing intervention compared with a conventional passive standing intervention on bone health in children with cerebral palsy who are nonambulatory.Four children in passive standers and 5 in dynamic standers were followed for 15 months (standing 30 min/d, 5 d/wk). Dual-energy x-ray absorptiometry scans of the distal femur were obtained at 3-month intervals to measure changes in bone mineral density (BMD), bone mineral content, and area.Increases in BMD were observed during dynamic standing (P < .001), whereas passive standing appeared to maintain the baseline BMD. Increases in bone mineral content were observed in each standing intervention (P < .001), with dynamic standing inducing greater increases. Increases in area were comparable between interventions (P = .315).Dynamic standing demonstrated the potential of moderate-magnitude, low-frequency loading to increase cortical BMD. Further investigations could provide insight into the mechanisms of bone health induced through loading interventions. HubMed – rehab
