Background: Upper limb (UL) motor impairment following stroke is a leading cause of functional limitations in activities of daily living. Robot-assisted therapy supports rehabilitation, but how its efficacy and the underlying neural mechanisms depend on the time after stroke is yet to be assessed., Aim: We investigated the response to an intensive protocol of robot-assisted rehabilitation in sub-acute and chronic stroke patients, by analyzing the underlying changes in clinical scores, electroencephalography (EEG) and end-effector kinematics. We aimed at identifying neural correlates of the participants' upper limb motor function recovery, following an intensive 2-week rehabilitation protocol., Design: Prospective cohort study., Setting: Inpatients and outpatients from the Neurorehabilitation Unit of Pisa University Hospital, Italy., Population: Sub-acute and chronic stroke survivors., Methods: Thirty-one stroke survivors (14 sub-acute, 17 chronic) with mild-to-moderate UL paresis were enrolled. All participants underwent ten rehabilitative sessions of task-oriented exercises with a planar end-effector robotic device. All patients were evaluated with the Fugl-Meyer Assessment Scale and the Wolf Motor Function Test, at recruitment (T0), end-of-treatment (T1), and one-month follow-up (T2). Along with clinical scales, kinematic parameters and quantitative EEG were collected for each patient. Kinematics metrics were related to velocity, acceleration and smoothness of the movement. Relative power in four frequency bands was extracted from the EEG signals. The evolution over time of kinematic and EEG features was analyzed, in correlation with motor recovery., Results: Both groups displayed significant gains in motility after treatment. Sub-acute patients displayed more pronounced clinical improvements, significant changes in kinematic parameters, and a larger increase in Beta-band in the motor area of the affected hemisphere. In both groups these improvements were associated to a decrease in the Delta-band of both hemispheres. Improvements were retained at T2., Conclusions: The intensive two-week rehabilitation protocol was effective in both chronic and sub-acute patients, and improvements in the two groups shared similar dynamics. However, stronger cortical and behavioral changes were observed in sub-acute patients suggesting different reorganizational patterns., Clinical Rehabilitation Impact: This study paves the way to personalized approaches to UL motor rehabilitation after stroke, as highlighted by different neurophysiological modifications following recovery in subacute and chronic stroke patients.

Introduction: The constant improvement of the diagnostic process and the crescent efficacy of treatment options for Breast Cancer have led to an increase in the survival rate of patients. Thereby, it has become fundamental for Breast Care Units to deal with short-, medium-, and long-term sequelae of the disease and its treatment. Among these, changes in posture seem to have a crucial role. This review aims to collect and summarize the current knowledge on postural disorders in Breast Cancer Survivors, focusing on evaluation methods and rehabilitation protocols., Evidence Acquisition: A systematic research was conducted on PubMed, Scopus and World of Science databases, considering all the studies published up to 2021. Case reports, case series, cross-sectional, retrospective and prospective studies were included. Narrative and Systematic reviews were excluded., Evidence Synthesis: After applying the eligibility criteria and bibliographic expansion, 55 articles were selected. Forty-four studies focused on the analysis and the quantification of postural abnormalities, showing a huge variability in population characteristics, valuative methods and outcome measures. Most of them are cross-sectional studies. Rehabilitation treatments have been considered in only 12 studies: all the rehabilitative treatments proved to be effective but, the heterogeneity among the evaluation methods has made a comparison impossible. Hence, we designed a complete evaluation protocol for the assessment of postural abnormalities in Breast Cancer Survivors. Our protocol has been drawn following the structure of International Classification of Functioning, Disability and Health., Conclusions: Our review pointed out the crescent interest of the current Literature on analysis and treatment of postural alterations in breast cancer survivors. Since the extreme variety of outcome measures made it impossible to give a clear indication for evaluation and treatment of this disorder, we designed a complete evaluation protocol for the assessment of postural abnormalities in breast cancer survivors, with the goal of guiding the design of new clinical trials on these subjects.

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 1 st , 2010 and December 31 st , 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 worldwide, 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 1, 2010 and October 31, 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.

Background: While the COVID-19 pandemic was spreading worldwide, the Italian government stated lockdown, with a drastic reorganization of healthcare systems. The psychological and social effects of the pandemic and the restrictions of freedom could have had a detrimental impact on people with physical disabilities, for whom well-being depends strongly on their social environment., Aim: Our main aim was to describe the overall impact of the pandemic on mental health, social condition and illness perception among patients with disabilities, to provide early interventions for this particularly vulnerable population. For this purpose, we performed a specific screening protocol to detect the prevalence of any psychological distress., Design: Cross-sectional observational study., Setting: Telephonic interview administered to patients and their caregivers attending the Unit of Neurorehabilitation at the University Hospital of Pisa., Population: 134 patients with physical disability related to neurological disorders, who had their outpatient appointment cancelled, because of the government dispositions, were enrolled., Methods: A specific questionnaire (COVID19-q) was designed to test patients' psycho-social state, including a section addressed to the caregiver. Moreover, a standardized psychological evaluation, using the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM), was also performed., Results: Results show a different impact in our study population compared to the general population on psychological aspect. Patients did not manifest any clinically relevant distress, as assessed with CORE-OM. However, patients with higher disability degree reported a statistically lower outcome in the social function, in the well-being domains and an increase in risk behavior. Results from COVID19-q show that most of our patients reported none or mild change in their psycho-social habits and perception of illness during lockdown. However, reduction of family cohesion and lack of healthcare support are two important aspects that people with disability had to face with during the pandemic emergency., Conclusions: People with physical disabilities surprisingly shown milder effects of the pandemic on their psychological state and good coping skills in facing social isolation, manifesting resilience resources. However, the is a need to give concrete support to healthcare and social care, especially in the management of severe disability., Clinical Rehabilitation Impact: This unexpected and reassuring result may reveal a worrying scenario regarding-the social participation and quality of life of people with disabilities: were they already in lockdown?

Background: Neurophysiological investigations represent powerful tools to shed light on brain plasticity in multiple sclerosis (MS) patients., Aim: We investigated the relationship between electroencephalography (EEG)-based connectivity, the extent of brain lesions and changes in motor performance after an intensive task-oriented circuit training (TOCT)., Design: Observational longitudinal study., Setting: Outpatients training program., Population: Sixteen MS patients (10F; mean age =51.4 years; range: 27-67; mean disease duration =15.1 years; range: 2-26; mean Expanded Disability Status Scale 4.4; range: 3.5-5.5), were included in our study., Methods: MS patients with mild gait impairment were evaluated through functional scales and submitted to TOCT. Resting-state EEG was performed before (T0) and after (T1) rehabilitation. Alpha-band weighted Phase Lag Index (wPLI) and broadband weighted Symbolic Mutual Information (wSMI) connectivity analyses were performed. White matter lesion load was measured using MRI prior to the TOCT. Neurophysiological and structural parameters were then related to behavioral changes., Results: Dynamic Gait Index significantly improved after TOCT (F(1,14) =13.10, P=0.003). Moreover, the interaction between TOCT and age was observed for changes in Timed Up and Go (TUG) performance (F(1,14) = 7.75, P=0.015), indicating that older patients only benefited in this measure. Regarding the relationship between EEG connectivity and TOCT outcome, we observed positive correlations between changes in TUG and strength (P=0.017) and efficiency (Pone-tail =0.029) of alpha-band wPLI connectivity at T0. Such correlation was mainly driven by antero-posterior regional interactions (P=0.038), rather than by inter-hemispheric connectivity (P=0.089). Moreover, we observed a positive correlation between performance improvements and wSMI connectivity at T1 (P=0.001) as well as the difference between T0 and T1 (P=0.005). Lesion load percentage was not related to functional improvement after TOCT (Pone-tail=0.137)., Conclusions: Results of the current study demonstrated that baseline alpha-band wPLI connectivity predicts TOCT outcome in MS patients. Moreover, broadband wSMI tracks neural changes that accompany treatment-related variations in motor performance., Clinical Rehabilitation Impact: Our findings suggest that EEG-based connectivity measures may represent a potential tool for customizing rehabilitative management of the disease.

Background: In patients affected by multiple sclerosis (MS) the disabilities increase during the progression of the disease, with a negative impact on quality of life. Rehabilitation improves motor performances, but remains unclear the role of psychological variables on motor recovery., Aim: The aim of this study was to investigate the role of the psychological well‑being during a rehabilitation care in MS patients with moderate to severe disability., Design: Longitudinal study., Setting: Outpatients in a Neurorehabilitation Unit of Pisa and Ferrara University Hospital., Population: 93 subjects affected by MS with moderate to severe degree of impairment were recruited (43 male, 50 female; mean age 53±11.19 years). In relation to the Expanded Disability Status Scale (EDSS) score the sample was divided in two group: Group 1 with moderate impairment (EDSS 4-5.5) and Group 2 with severe impairment (EDSS 6-7)., Methods: Psychological and functional status was assessed before and after a motor rehabilitative treatment, appropriate to their clinical needs. Parameters collected were: Short Form 36, Patient Health Questionnaire, Fatigue Severity Scale, 6-minute walking test and 10-meter walking test., Results: Mood disorders, low quality of life (QoL) and high perceived fatigue are characteristic symptoms in our sample. Results do not show a direct correlation with motor impairment. Mood improves in both groups, while walking endurance and speed ability recovers only in Group 1, on the contrary QoL improves only in Group 2. Regression analysis show that in Group 1 a better QoL predicts a higher motor recovery, whereas in Group 2 the improvement of walking endurance influences the subjective well‑being at the discharge., Conclusions: Subjective well‑being is related with the perception of the new condition of life. In less impaired patients psychological status can influence the liability toward rehabilitation treatment, while in more impaired patients motor recovery affect well‑being. Therefore, the psychological counselling should be provided during the rehabilitation treatment in order to achieve a successful patients' care., Clinical Rehabilitation Impact: Our approach contributes to bring out the role of subjective factors on motor rehabilitation outcome and the functional recovery effect on the psychological well‑being. The knowledge of subjective needs related to disability degree should be used to customize an appropriate care in MS patients.

Background: Robotics and related technologies are realizing their promise to improve the delivery of rehabilitation therapy but the mechanism by which they enhance recovery is still unknown. The electromechanical-driven gait orthosis Lokomat has demonstrated its utility for gait rehabilitation after stroke., Aim: To test the efficacy of Lokomat in gait retraining and to investigate the neurophysiological mechanisms underlying the recovery process., Design: Case series study., Setting: Unit of Neurorehabilitation of a University Hospital., Population: Fifteen patients with post-stroke hemiparesis., Methods: Patients underwent a six weeks rehabilitative treatment provided by Lokomat. The outcome measures were: Fugl-Meyer Motor Scale (FMMS), Berg Balance Scale (BBS), 10 metres Walking Test (10mWT), Timed Up and Go test (TUG), 6 Minute Walking Test (6MWT). Strength and Motor Unit firing rate of vastus medialis (VM) were analyzed during isometric knee extension through an isokinetic dynamometer and surface EMG recording., Results: An increase of duration and covered distance, a decrease of body weight support and guidance force on the paretic side along the sessions were observed. The FMMS, the BBS, the TUG and the 6MWT demonstrated a significant improvement after the training. No increase of force was observed whereas a significant increase of firing rate of VM was recorded., Conclusion: The evidence that the improvement of walking ability observed in our study determines a significant increase of firing rate of VM not accompanied by an increase of force could suggest an effect of training on motorneuronal firing rate that thus contributes to improve motor control., Clinical Rehabilitation Impact: Given the current wide use of robotics in gait retraining after stroke, our approach can contribute to clarify the mechanisms underlying its rehabilitative impact so as to incorporate the findings of evidence-based practice into appropriate treatment plans for persons poststroke.

Background: Polymyositis (PM) and Dermatomyositis (DM) are chronic, inflammatory and autoimmune skeletal muscle disorders characterized by reduced muscle strength, fatigue and myalgia. While inflammation causes muscle damage in the early phase, metabolic alterations such as an impairment of oxidative metabolism seem to be responsible for the disability in the chronic phase of the disease., Aim: To assess muscle oxidative efficiency and to test the effect of aerobic training in a group of PM/DM patients., Design: A case-control study and a within-group comparison. SETTING. Outpatients of the Unit of Neurorehabilitation of the University Hospital of Pisa., Population: 20 patients with myositis (15 PM and 5 DM) and 15 healthy subjects as a control group., Methods: The test consisted of an incremental, sub-maximal aerobic exercise on a treadmill; haematic lactate was assessed at rest and after 1', 5', 10' and 30' minutes from the end of the exercise. A within-group comparison was conducted on four of the PM patients (P group). They were subjected to six weeks aerobic training. Lactate curve and functional tests were assessed before and after the treatment., Results: A precocious fatigability and significantly higher values of lactate at rest and after the exercise were observed in patients. In the P group mean lactate levels were significantly decreased after the treatment and an improvement of muscle performance was observed., Conclusion: Abnormal blood lactate levels suggested an impaired muscle oxidative efficiency in PM/DM patients. A specific aerobic training program reduced lactate levels and relieved fatigue symptoms in a within-group of four of the PM patients., Clinical Rehabilitation Impact: Such a specific aerobic training program could be introduced in everyday practice for the rehabilitative treatment of PM/DM patients.
