RESUMO
STUDY DESIGN: Multicentre cross-sectional study. OBJECTIVE: The objective of this study is to evaluate prevalence, location and characteristics of pain in hospital inpatients people with spinal cord injury (SCI). SETTING: Ten Italian rehabilitation centres specialized in spinal injury care, where inpatients are admitted both after the acute lesion and for late complications (time since injury, median [IQR]: 0.8 [0.2-8.2] years). METHODS: All the persons were submitted to AIS scale assessment [1] and modified Ashworth scale [2]; personal data and anamnesis were recorded; any pain within 1 week was investigated and the International Spinal Cord Injury Pain Basic Data Set (ISCIPBDS) Italian version [3] was administered by physicians expert in type of pain definition. RESULTS: Of 385 included persons, 275 (72%) suffered pain, with the score value median [IQR]: 6 [4-8]. The worst pain of the person was nociceptive in 52% and neuropathic in 48% of the cases; 46% of nociceptive pain was located in the neck-shoulder region, whereas 67% of neuropathic pain was located in the sublesional part of the body. In 48% of the whole population, spasticity was observed but only 74% of them had pain. Being old and female are associated with high pain development, OR (95% CI): 1.24 (1.01-1.04) and 1.83 (1.05-3.20), respectively. CONCLUSIONS: A high prevalence of pain is confirmed in persons with SCI, with both nociceptive and neuropathic pain characteristics. Only old age and female sex resulted as variables highly associated with pain.

BACKGROUND: In the last years, there has been an intense technological development of robotic devices for gait rehabilitation in spinal cord injury (SCI) patients. The aim of the present study was to evaluate energy cost and psychological impact during a rehabilitation program with two different types of robotic rehabilitation systems (stationary system on a treadmill, Lokomat, and overground walking system, Ekso GT). METHODS: Fifteen SCI patients with different injury levels underwent robot-assisted gait training sessions, divided into 2 phases: in the first phase, all subjects completed 3 sessions both Lokomat and Ekso GT. Afterwards, participants were randomly assigned to Lokomat or the Ekso for 17 sessions. A questionnaire, investigating the subjective psychological impact (SPI) during gait training, was administered. The functional outcome measures were oxygen consumption (VO2), carbon dioxide production (VCO2), metabolic equivalent of task (MET), walking economy, and heart rate (HR). RESULTS: The metabolic responses (7.73 ± 1.02 mL/kg/min) and MET values (3.20 ± 1.01) during robotic overground walking resulted to be higher than those during robotic treadmill walking (3.91 ± 0.93 mL/kg/min and 1.58 ± 0.44; p < 0.01). Both devices showed high scores in emotion and satisfaction. Overground walking resulted in higher scores of fatigue, mental effort, and discomfort while walking with Lokomat showed a higher score in muscle relaxation. All patients showed improvements in walking economy due to a decrease in energy cost with increased speed and workload. CONCLUSIONS: Overground robotic-assisted gait training in rehabilitation program needs higher cognitive and cardiovascular efforts than robot-assisted gait training on a treadmill.

STUDY DESIGN: Prospective, quasi-experimental study, pre- and post-design, single arm study. OBJECTIVES: Investigate whether persons affected by SCI can safely experience walking function using Robotic Exoskeletons and Functional Electrical Stimulation (FES). SETTING: Inpatient METHODS: 52 persons with SCI were recruited (36 completed the protocol) and assigned to one of two groups based on their Lower Limb Motor Scores (LEMS): Group A: LEMS ≥ 10 and Group B: LEMS < 10. Participants in Group A (n = 19) underwent 20 sessions of Robot-Assisted Gait Training (RAGT) on a treadmill followed by 20 sessions of FES during Overground Gait (FES-OG). Participants in Group B (n = 17) received 20 sessions of FES-cycling followed by 20 sessions of overground RAGT. The main outcome measures were: WISCI-II, 10MWT, 6MWT, TUG and SCIM-II. RESULTS: 36 persons completed the study with no complications; only 4 of the 16 dropped out because of mild complications during the RAGT. Participants in Group A exhibited significant improvements in WISCI-II, 10MWT, 6MWT and TUG (p < 0.05), while those in Group B did not significantly improve their gait function but their walking velocity and resistance with the assistance of the robotic exoskeleton increased. SCIM-II scores increased followed therapy only in Group A. CONCLUSIONS: Persons affected by SCI can safely experience their walking function with RAGT and FES therapy; only few mild complications were observed. Our data provides initial evidence of the potential value of these technologies, especially in persons with SCI having LEMS > 10.

BACKGROUND AIMS: Mesenchymal stromal cells (MSCs) modulate the immune response and represent a potential treatment for inflammatory and autoimmune diseases. We hypothesized that this feature could be potentiated by co-administering anti-inflammatory cytokines. In this article, we asked whether engineering of Wharton Jelly-derived human MSCs (WJ-hMSCs) to express an anti-inflammatory cytokine increases cell immunomodulatory properties without altering their native features. METHODS: We used Epstein-Barr virus-derived interleukin-10 (vIL-10), which shares some immunosuppressive properties with human IL-10 but lacks immunostimulatory activity. Engineering was accomplished by transducing WJ-hMSCs with a self-inactivating feline immunodeficiency virus-derived vector co-expressing vIL-10 and herpes simplex virus type-1 thymidine kinase (TK). TK was added to allow future tracking of WJ-hMSC in vivo by positron electron tomography (PET). RESULTS: The results show that (i) expression of TK and/or vIL-10 does not change WJ-hMSC phenotypic and functional properties; (ii) vIL-10 is secreted, biologically active and enhances the immunosuppressing functions of WJ-hMSCs; (iii) v-IL10 and TK can be produced simultaneously by the same cells and do not interfere with each other. DISCUSSION: WJ-hMSCs engineered to secrete vIL-10 could be a powerful tool for adoptive cell therapy of immune-mediated diseases, and therefore, additional studies are warranted to confirm their efficacy in suitable animal disease models.

BACKGROUND: The recovery of walking after stroke is a priority goal for recovering autonomy. In the last years robotic systems employed for Robotic Assisted Gait Training (RAGT) were developed. However, literature and clinical practice did not offer standardized RAGT protocol or pattern of evaluation scales. OBJECTIVE: This systematic review aimed to summarize the available evidence on the use of RAGT in post-stroke, following the CICERONE Consensus indications. METHODS: The literature search was conducted on PubMed, Cochrane Library and PEDro, including studies with the following criteria: 1) adult post-stroke survivors with gait disability in acute/subacute/chronic phase; 2) RAGT as intervention; 3) any comparators; 4) outcome regarding impairment, activity, and participation; 5) both primary studies and reviews. RESULTS: Sixty-one articles were selected. Data about characteristics of patients, level of disability, robotic devices used, RAGT protocols, outcome measures, and level of evidence were extracted. CONCLUSION: It is possible to identify robotic devices that are more suitable for specific phase disease and level of disability, but we identified significant variability in dose and protocols. RAGT as an add-on treatment seemed to be prevalent. Further studies are needed to investigate the outcomes achieved as a function of RAGT doses delivered.

BACKGROUND: Many robots are available for gait rehabilitation (BWSTRT and ORET) and their application in persons with SCI allowed an improvement of walking function. OBJECTIVE: The aim of the study is to compare the effects of different robotic exoskeletons gait training in persons with different SCI level and severity. METHODS: Sixty-two studies were included in this systematic review; the study quality was assessed according to GRADE and PEDro's scale. RESULTS: Quality assessment of included studies (nâ=â62) demonstrated a prevalence of evidence level 2; the quality of the studies was higher for BWSTRT (excellent and good) than for ORET (fair and good). Almost all persons recruited for BWSTRT had an incomplete SCI; both complete and incomplete SCI were recruited for ORET. The SCI lesion level in the persons recruited for BWSTRT are from cervical to sacral; mainly from thoracic to sacral for ORET; a high representation of AIS D lesion resulted both for BWSTRT (30%) and for ORET (45%). The walking performance, tested with 10MWT, 6MWT, TUG and WISCI, improved after exoskeleton training in persons with incomplete SCI lesions, when at least 20 sessions were applied. Persons with complete SCI lesions improved the dexterity in walking with exoskeleton, but did not recover independent walking function; symptoms such as spasticity, pain and cardiovascular endurance improved. CONCLUSION: Different exoskeletons are available for walking rehabilitation in persons with SCI. The choice about the kind of robotic gait training should be addressed on the basis of the lesion severity and the possible comorbidities.

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: 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.

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.

BACKGROUND: Intrathecal Baclofen is available to treat severe generalized spasticity in Multiple Sclerosis (MS) unresponsive to oral drug delivery. OBJECTIVE: The aims of this study were to investigate the effects and the drug dosage of intrathecal Baclofen in a selected population of MS patients, affected by severe spasticity at long term follow-up. METHODS: A prospective cohort study of 14 MS patients is presented. Spasticity and pain were periodically assessed and the Baclofen dosage was adjusted. RESULTS: The initial Baclofen dosage was 136.2 ± 109.3 µg, then it was increased at 12 months to 228.6 ± 179.2 µg (pâ<â0.05). The subsequent dose adjustments did not result in significant changes up to 76 months. Spasticity on the lower limbs decreased significantly from pre-implantation assessment (median: 3.5, IQR: 3.0-4.0) to 12 months evaluation (median: 0.5, IQR: 0.0-2.0) (pâ<â0.001); no further decrease was observed after 24 months (median: 0.5, IQR: 0.0-1.5); when pain was present, it decreased. Some effects on cerebellar symptoms were observed. Botulinum toxin injections were used with intrathecal Baclofen therapy. CONCLUSIONS: A reduced spasticity and pain was observed after the intrathecal Baclofen infusion for at least 76 months. To obtain these results a dosage adjustment was needed only in the first year after the implantation.

BACKGROUND: Powered robotic exoskeletons represent an emerging technology for the gait training of Spinal Cord Injured (SCI) persons. The analysis of the psychological and physical impact of such technology on the patient is crucial in terms of clinical appropriateness of such rehabilitation intervention for SCI persons. OBJECTIVE: To investigate the acceptability of overground robot-assisted walking and its effect on pain and spasticity. METHODS: Twenty-one SCI persons participated in a walking session assisted by a powered robotic exoskeleton. Pain assessed using a Numeric Rating Scale (NRS) and muscle spasticity, assessed as subjective perception using an NRS scale and as objective assessment using the Modified Ashworth scale and the Penn scale, were evaluated before and after the walking experience. Positive and negative sensations were investigated using a questionnaire. The patient's global impression of change (PGIC) scale was administrated as well. RESULTS: After the walking session a significant decrease in the muscle spasticity and pain intensity was observed. The SCI persons recruited in this study reported (i) a global change after the walking session, (ii) high scores on the positive and (iii) low scores on the negative sensations, thus indicating a good acceptability of the robot-assisted walking. CONCLUSIONS: The overground robot-assisted walking is well accepted by SCI persons and has positive effects in terms of spasticity and pain reduction.

BACKGROUND: Rabbits provide an excellent model for many animal and human diseases, such as cardiovascular diseases, for the development of new vaccines in wound healing management and in the field of tissue engineering of tendon, cartilage, bone and skin.The study presented herein aims to investigate the biological properties of bone marrow rabbit MSCs cultured in different conditions, in order to provide a basis for their clinical applications in veterinary medicine. FINDINGS: MSCs were isolated from 5 New Zealand rabbits. Fold increase, CFU number, doubling time, differentiation ability and immunophenotype were analyzed.With the plating density of 10 cells/cm2 the fold increase was significantly lower with DMEM-20%FCS and MSCs growth was significantly higher with alphaMEM-hEGF. The highest clonogenic ability was found at 100 cell/cm2 with MSCBM and at 10 cell/cm2 with M199. Both at 10 and 100 cells/cm2, in alphaMEM medium, the highest CFU increase was obtained by adding bFGF. Supplementing culture media with 10%FCS-10%HS determined a significant increase of CFU. CONCLUSION: Our data suggest that different progenitor cells with differential sensitivity to media, sera and growth factors exist and the choice of culture conditions has to be carefully considered for MSC management.

OBJECTIVE: To describe the demographic and clinical characteristics and the clinical course of patients with nontraumatic spinal cord injury (SCI). DESIGN: A multicenter prospective study. SETTING: Thirty-two rehabilitation centers in several Italian regions. PARTICIPANTS: Patients with nontraumatic SCI (N=330) on first admission (February 1, 1997-January 31, 1999) to rehabilitation centers. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Indicators of rehabilitation process quality were efficient bladder and bowel management. The indica-tor of neurologic recovery was improvement in American Spinal Injury Association Impairment Scale (AIS) level at discharge. The indicator of rehabilitation outcome was return home. Length of stay (LOS) was also measured as an indicator of the care process. RESULTS: Of the 330 patients, 30% exhibited an improvement in AIS classification at discharge, and 73% returned home. In multivariate analysis, a longer LOS was associated with vascular etiology, complete lesions, residence outside the district of the rehabilitation center, and presence of clinical complications. Neurologic improvement was related to incompleteness of the lesion and longer LOS. Factors predicting a return home were married status, incompleteness of lesion, clinical improvement, efficient bowel and bladder management, absence of pressure ulcers, and longer LOS. CONCLUSIONS: Patients showed long waiting times between diagnosis and initiation of rehabilitation, a good chance of improvement on the AIS, and low rates of home returns.
