Equinovarus foot deformity (EVFD) compromises several prerequisites of walking and increases the risk of falling. Guidelines on rehabilitation following EVFD surgery are missing in current literature.The aim of this study was to analyze safety and adherence to an early rehabilitation treatment characterized by immediate weight bearing with an ankle-foot orthosis (AFO) in hemiplegic patients after EVFD surgery and to describe gait changes after EVFD surgical correction combined with early rehabilitation treatment.Retrospective observational cohort study.Inpatient rehabilitation clinic.Forty-seven adult patients with hemiplegia consequent to ischemic or haemorrhagic stroke (L/R 20/27, age 56±15 years, time from lesion 6±5 years).A specific rehabilitation protocol with a non-articulated AFO, used to allow for immediate gait training, started one day after EVFD surgery. Gait analysis (GA) data before and one month after surgery were analyzed. The presence of differences in GA space-time parameters, in ankle dorsiflexion (DF) values and peaks at initial contact (DF at IC), during stance (DF at St) and swing (DF at Sw) were assessed by the Wilcoxon Test while the presence of correlations between pre- and post-operative values by Spearman's correlation coefficient.All patients completed the rehabilitation protocol and no clinical complications occurred in the sample. Ankle DF increased one month after surgery at all investigated gait phases (Wilcoxon Test, P0.0001), becoming neutral at IC. Significant (P0.05) variations were found for stride length, stride width, anterior step length of the affected side and for the duration of the double support phase of the contralateral side. The postsurgery ankle DF at St was found to be correlated (R=0.81, P0.0001) with its pre-surgery value, thus being predictable. Weaker significant correlations were found for DF at Sw and DF at IC, where contribution from the dorsiflexor muscles is required in addition to calf muscle passive lengthening.An orthosis-assisted immediate rehabilitation associated with surgical procedure is safe and may be suitable to correct EVFD by restoring both the neutral heel foot-ground contact and the ankle DF peaks during stance and swing at one month from surgery.The proposed protocol is a safe and potentially useful rehabilitative approach after EVFD surgical correction in stroke patients.

BACKGROUND: Gait impairments are common disabling symptoms of Parkinson’s disease (PD). Among the approaches for gait rehabilitation, interest in robotic devices has grown in recent years. However, the effectiveness compared to other interventions, the optimum amount of training, the type of device, and which patients might benefit most remains unclear. OBJECTIVE: To conduct a systematic review about the effects on gait of robot-assisted gait training (RAGT) in PD patients and to provide advice for clinical practice. METHODS: A search was performed on PubMed, Scopus, PEDro, Cochrane library, Web of science, and guideline databases, following PRISMA guidelines. We included English articles if they used a robotic system with details about the intervention, the parameters, and the outcome measures. We evaluated the level and quality of evidence. RESULTS: We included twenty papers out of 230 results: two systematic reviews, 9 randomized controlled trials, 4 uncontrolled studies, and 5 descriptive reports. Nine studies used an exoskeleton device and the remainders end-effector robots, with large variability in terms of subjects’ disease-related disability. CONCLUSIONS: RAGT showed benefits on gait and no adverse events were recorded. However, it does not seem superior to other interventions, except in patients with more severe symptoms and advanced disease.

INTRODUCTION: There is growing evidence on the efficacy of gait robotic rehabilitation in patients with multiple sclerosis (MS), but most of the studies have focused on gait parameters. Moreover, clear indications on the clinical use of robotics still lack. As part of the CICERONE Italian Consensus on Robotic Rehabilitation, the aim of this systematic review was to investigate the existing evidence concerning the role of lower limb robotic rehabilitation in improving functional recovery in patients with MS. EVIDENCE ACQUISITION: We searched for and systematically reviewed evidence-based studies on gait robotic rehabilitation in MS, between January 1st, 2010 and December 31st, 2020, in the following databases: Cochrane Library, PEDro, PubMed and Google Scholar. The study quality was assessed by the 16-item assessment of multiple systematic reviews 2 (AMSTAR 2) and the 10-item PEDro scale for the other research studies. EVIDENCE SYNTHESIS: After an accurate screening, only 17 papers were included in the review, and most of them (13 RCT) had a level II evidence. Most of the studies used the Lokomat as a grounded robotic device, two investigated the efficacy of end-effectors and two powered exoskeletons. Generally speaking, robotic treatment has beneficial effects on gait speed, endurance and balance with comparable outcomes to those of conventional treatments. However, in more severe patients (EDSS >6), robotics leads to better functional outcomes. Notably, after gait training with robotics (especially when coupled to virtual reality) MS patients also reach better non-motor outcomes, including spasticity, fatigue, pain, psychological well-being and quality of life. Unfortunately, no clinical indications emerge on the treatment protocols. CONCLUSIONS: The present comprehensive systematic review highlights the potential beneficial role on functional outcomes of the lower limb robotic devices in people with MS. Future studies are warranted to evaluate the role of robotics not only for walking and balance outcomes, but also for other gait-training-related benefits, to identify appropriate outcome measures related to a specific subgroup of MS subjects' disease severity.

Introduction Stroke is the third leading cause of adult disability world-wide, and lower extremity motor impairment is one of the major determinants of long-term disability. Although robotic therapy is becoming more and more utilized in research protocols for lower limb stroke rehabilitation, the gap between research evidence and its use in clinical practice is still significant. The aim of this study was to determine the scope, quality, and consistency of guidelines for robotic lower limb rehabilitation after stroke, in order to provide clinical recommendations. Evidence acquisition We systematically reviewed stroke rehabilitation guideline recommendations between January 1st, 2010 and October 31th, 2020. We explored electronic databases (n=4), guideline repositories and professional rehabilitation networks (n=12). Two independent reviewers used the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, and brief syntheses were used to evaluate and compare the different recommendations, considering only the most recent version. Evidence synthesis From the 1219 papers screened, ten eligible guidelines were identified from seven different regions/countries. Four of the included guidelines focused on stroke management, the other six on stroke rehabilitation. Robotic rehabilitation is generally recommended to improve lower limb motor function, including gait and strength. Unfortunately, there is still no consensus about the timing, frequency, training session duration and the exact characteristics of subjects who could benefit from robotics. Conclusions Our systematic review shows that the introduction of robotic rehabilitation in standard treatment protocols seems to be the future of stroke rehabilitation. However, robot assisted gait training (RAGT) for stroke needs to be improved with new solutions and in clinical practice guidelines, especially in terms of applicability.

Historical, educational, and technical barriers have been reported to limit the use of surface electromyography (sEMG) in clinical neurorehabilitation settings. In an attempt to identify, review, rank, and interpret potential factors that may play a role in this scenario, we gathered information on (1) current use of sEMG and its clinical potential; (2) professional figures primarily dealing with sEMG; (3) educational aspects, and (4) possible barriers and reasons for its apparently limited use in neurorehabilitation. To this aim, an online 30-question survey was sent to 52 experts on sEMG from diverse standpoints, backgrounds, and countries. Participants were asked to respond to each question on a 5-point Likert scale or by ranking items. A cut-off of 75% agreement was chosen as the consensus threshold. Thirty-five invitees (67%) completed the electronic survey. Consensus was reached for 77% of the proposed questions encompassing current trends in sEMG use in neurorehabilitation, educational, technical, and methodological features as well as its translational utility for clinicians and patients. Data evidenced the clinical utility of sEMG for patient assessment, to define the intervention plan, and to complement/optimize other methods used to quantify muscle and physical function. The aggregate opinion of the interviewed experts confirmed that sEMG is more frequently employed in technical/methodological than clinical research. Moreover, the slow dissemination of research findings and the lack of education on sEMG seem to prevent prompt transfer into practice. The findings of the present survey may contribute to the ongoing debate on the appropriateness and value of sEMG for neurorehabilitation professionals and its potential translation into clinical settings. ispartof: FRONTIERS IN NEUROLOGY vol:11 ispartof: location:Switzerland status: published

The assessment of walking function alterations is a key issue to design effective rehabilitative interventions in sub-acute stroke patients. Nevertheless, the objective quantification of these alterations remains a challenge. Clinical rating scales are commonly used in clinical practice, but have been proven prone to errors associated to the evaluator subjective perception. On the other hand, instrumental measurement of trunk acceleration can be exploited for an objective quantitative characterization of gait function, but it is not applied in routine clinical practice, because the resulting quantitative indexes have not been related to the clinically information, conventionally provided by the rating scales. To overcome this limitation, the relationship between the indexes, in specific clinical conditions, and rating scale must be better investigated, to support their exploitability in the clinical practice as a fast and reliable screening tool. Thirty-one sub-acute stroke patients (17 with and 14 without cane) participated in the study. All were assessed with 6 rating scales (MI, TCT, MRI, FAC, WHS, CIRS) and 2 functional tests (2MWT and TUG). Sample Entropy (SEN) and Recurrence Quantification Analysis (RQA) in AP, ML and V directions were calculated over 2MWT and walking section of TUG. The influence of assessment task and cane was analysed, as well as correlation of SEN and RQA indexes with clinical rating scales. SEN and RQA on the medio-lateral plane resulted influenced by the use of the cane, while the correlations between indexes and clinical scales showed that SEN and RQA for antero-posterior direction correlate positively with WHS.

Il Porto Vecchio di Trieste rappresenta un importante esempio di architettura del periodo della rivoluzione industriale. Il potenziamento del porto divenne una necessità durante il XIX secolo. Le criticità incontrate nella realizzazione furono risolte con soluzioni tecniche all’avanguardia. Di particolare interesse risulta la sperimentazione di tecniche innovative del Calcestruzzo Armato. La rivoluzione dei traffi ci commerciali nel XX secolo e la realizzazione del “Porto Nuovo” nella zona Est della città, segnarono il declino del Porto Vecchio. Oggi l’area complessiva è oggetto di un’iniziativa che ha l’obiettivo di restituirla alla città. In una visione di recupero complessivo, questo contributo si pone l’obiettivo di valorizzazione le tecniche costruttive utilizzate, tramite proposte per il recupero delle stesse.

Il Porto Vecchio di Trieste rappresenta un esempio di architettura riferibile al patrimonio archeologico industriale di sicuro interesse per il suo contenuto culturale e storico. Si è sviluppata una visione metaprogettuale, declinata alle scale urbanistica ed architettonica, che si è posta l’obiettivo di restituire tale patrimonio alla città, valorizzando gli elementi caratteristici degli edifici e, al contempo, in una visione di coerente sostenibilità del recupero stesso. I risultati della ricerca acquistano valore in considerazione alle analogie formali e costruttive riscontrate negli edifici e, quindi, alla possibilità una ripetibilità delle azioni progettuali e di intervento per il recupero di tale patrimonio.

Late onset Pompe disease (LOPD) is characterized by significant motor disabilities, which affect in particular ambulation. Only one study reports on spatial-temporal parameters of gait assessed in a clinical heterogeneous group of unrelated patients. In this study spatiotemporal and kinematic gait patterns are described in a genetically homogenous group of LOPD patients using 3d movement analysis. 7 LOPD siblings, harbouring the same GAA mutations compound, were assessed with clinical scales and with 3d movement analysis to measure spatial-temporal and kinematic parameters during gait cycle and “sit to stand test”. Relevant abnormalities were observed either in spatial-temporal and kinematic parameters. The former consisted in a trend towards a decreased velocity and cadence, a prolonged time in double limb support, shorter step and stride length, and a widening of base of support; the latter in an increased anterior pelvic-tilt and posterior trunk-tilt during the whole gait cycle, a decreased pelvic obliquity, active hip extension and ankle dorsiflexion. This study shows, in homogenous group of LOPD patients, either spatial-temporal and kinematic deviations that may improve understanding of the musculoskeletal alterations, the evolution of disease and the answer to the enzyme replacement therapy.

La normativa tecnica individua, all’interno del complesso quadro della sostenibilità, le esigenze ed i requisiti connotanti, partendo dagli aspetti energetici ed allargandosi poi ai temi ambientali, seguendo un processo di strutturazione che comprende anche gli aspetti economici e sociali. Si delineano, perciò, quadri di requisiti volti a determinare processi edilizi “sostenibili” ed a certificare la qualità degli stessi. La ricerca svolta, a partire dalla normativa tecnica inerente la sostenibilità ambientale e l’efficienza energetica degli edifici, ne affronta i requisiti connotanti, indagando le caratteristiche e le possibilità offerte da strumenti tecnici che, capaci di definire determinate prestazioni, possono essere impiegati come valido strumento progettuale.
