Can overestimation of walking ability increase the risk of falls in people in the subacute stage after stroke on their return home?
No full textPurpose: Falls are common in patients who have had a stroke who return home after neurorehabilitation.
Some studies have found that walking speed inversely correlates with the risk of falls.
Scope: This study examined whether comparison between comfortable self-selected walking speed and
maximum maintainable speed is informative with regard to the risk of falls in patients with stroke.
Methods: A prospective cohort study was performed with 75 ambulant stroke patients. At discharge, the
Barthel Index score and performance at the 10-m and 6-min walking tests were assessed. Number of falls
was recorded by telephone interview every two months for one year. Regression analysis was performed
to identify factors that were related to the risk of falls.
Results: Using forward multiple linear regression, only the ratio between walking speeds on the 6-min
and 10-m tests was linked to the number of falls in the year after discharge (R = 0.451, p < 0.001,
OR = 0.046). Patients who chose a walking speed for short distances that was not maintainable long term
fell more frequently.
Conclusions: A discrepancy between short and long-term walking speed can help in identifying subjects
in the subacute stage after stroke with an increased risk of suffering a fall

No full textIl numero meraviglioso: la sezione aurea. Bellezza della matematica, armonia dell'universo, musica della natura
No full textCosa accomuna i battiti del nostro cuore al Partenone, i movimenti delle nostre dita alla Venere di Milo, la forma dei girasoli alla Cappella Sistina? È la bellezza delle loro proporzioni, tutte legate a un unico piccolo numero irrazionale noto col nome di sezione aurea (φ). Questo libro tratta di questo numero meraviglioso, ma non è un libro di formule matematiche, né di formule magiche, non è un saggio, né un trattato di misticismo numerologico. È l’avvincente racconto di come la sezione aurea sia riuscita ad appassionare Platone e terrorizzare Pitagora, ispirare Leonardo e fare innamorare Keplero. Ripercorrendo la storia di questo numero attraverso aneddoti e curiosità, ripercorriamo il cammino dell’uomo: non un continuo lento progresso, bensì una corsa a ostacoli piena di cadute, di ritorni al passato e salti nel futuro, di clamorosi errori e geniali intuizioni. Raccontato come fosse una canzone, questo libro ci svela, attraverso la sezione aurea, l’armonia del mondo, una musica da ascoltare con gli occhi, fino a scoprirla nel ritmo dei nostri passi
Why Do Patients with Cerebellar Ataxia Not Use Environmental Cues for Reducing Unpredictability of Sudden Gait Stopping?
No full textVirtual reality in cognitive and motor rehabilitation: facts, fiction and fallacies
No full textOver recent decades many researchers and clinicians have started to use Virtual Reality (VR) as a new technology for implementing innovative rehabilitation treatments in cognitive and motor domains. However, the expression 'VR' has often also been improperly used to refer to video games. Further, VR efficacy, often confused with that of video-game exercises, is still debated. Areas covered: In this review, we provide the scientific rationale for the advantages of using VR systems in rehabilitation and investigate whether the VR could really be a promising technique for the future of rehabilitation of patients, or if it is just an entertainment for scientists. In addition, we describe some of the most used devices in VR with their potential advantages for research and provide an overview of the recent evidence and meta-analyses in rehabilitation. Expert commentary: We highlight the efficacy and fallacies of VR in neurorehabilitation and discuss the important factors emerging from the use of VR, including the sense of presence and the embodiment over a virtual avatar, in developing future applications in cognitive and motor rehabilitation
Walking there: Environmental influence on walking-distance estimation
No full textIn a dark environment, when vision is excluded, humans are usually able to walk towards a target the position of which was previously memorized. Changes in spatio-temporal gait parameters, the presence of obstacles on the ground or pathway tilt can affect their performances. The aim of this study was to investigate the influence of the environment on this ability. We have enrolled sixty healthy subjects, separately tested in a small indoor and in an outdoor open-field environment. In experiment 1, significant differences were found between 15 indoor and 15 outdoor blindfolded walkers. According to previous studies, the distances walked outdoors were not significantly different from the three-tested target’s distances (3 m, 6 m and 10 m). Conversely, a systematic and significant undershooting was observed for lindfolded indoor walkers for all the three distances (errors:−0.34,−0.73 and −1.99 m, respectively). This indoor undershooting was found related to shorter steps not compensated by any increment of the step number. In experiment 2, also the perception of the indoor distance resulted underestimated in other two tested groups of 15 subjects each. But the perceived distance resulted poorly correlated with
motor performances (R = 0.23, p = 0.410). In spite of the fact that the errors were consistent among trials, when indoor walkers could not access to environmental acoustic features, their performance resulted highly variable among subjects, but it improved, on average. At the light of these results, the environment seems acting as a selective tuning between different strategies
