Polar bosons in one-dimensional disordered optical lattices

2013

We analyze the effects of disorder and quasi-disorder on the ground-state properties of ultra-cold polar bosons in optical lattices. We show that the interplay between disorder and inter-site interactions leads to rich phase diagrams. A uniform disorder leads to a Haldane-insulator phase with finite parity order, whereas the density-wave phase becomes a Bose-glass at very weak disorder. For quasi-disorder, the Haldane insulator connects with a gapped generalized incommesurate density wave without an intermediate critical region.

Effects of supervised slackline training on postural instability, freezing of gait, and falls efficacy in people with Parkinson's disease.

2016

The aim of this study was to assess whether supervised slackline training reduces the risk of falls in people with Parkinson's disease (PD).Twenty-two patients with idiopathic PD were randomized into experimental (EG, N = 11) and control (CG, N = 11) groups. Center of Pressure (CoP), Freezing of Gait (FOG), and Falls Efficacy Scale (FES) were assessed at pre-test, post-test and re-test. Rate perceived exertion (RPE, Borg's 6-20 scale) and local muscle perceived exertion (LRPE) were also assessed at the end of the training sessions.The EG group showed significant improvements in FOG and FES scores from pre-test to post-test. Both decreased at re-test, though they did not return to pre-test l…

Postural control and physiological responses to a simulated match in U-20 judo competitors

2018

The aim was to evaluate the effects of judo combat on the athletes’ postural control (PC) and physiological loading before, during and after a simulated match. Seventeen under-20 regional and national level athletes completed one modified 7-min match. At baseline, during the combat (3rd and 7th minutes) and 2-min post-match centre of pressure (CoP) parameters were assessed. Heart rate (HR), blood lactate (BLa) and rating of perceived exertion (RPE) and local RPE (LRPE) were collected. Significant increments were observed in CoP mean positioning and velocity at 3rd and 7th minutes, but the CoP deviation in both axes was unaffected. HR and BLa were elevated at 3rd and 7th minutes, and they re…

Effects of progressive resistance exercise in akinetic-rigid Parkinson's disease patients: a randomized controlled trial.

2017

Progressive resistance exercise (PRE) can have a positive effect in individuals with Parkinson’s disease (PD). However, the effect of PRE may vary with the clinical subtype of PD. To date, no study has assessed the effects of PRE in the different subtypes of PD. AIM: The aim of the present study was to assess the effects of PRE in PD patients with akinesia and rigidity (AR-subtype). DESIGN: A randomized controlled trial was conducted. SETTING: Outpatients clinics of the Bierzo Parkinson Association (Ponferrada, Spain) and the Asturias Parkinson Association (Oviedo, Spain). POPULATION: Twenty-eight patients with AR-subtype PD were randomized into an Experimental Group (EG, N.=13) and Control…
