Understanding the family burden and caregiver role in stroke rehabilitation: insights from a retrospective study.

INTRODUCTION: Stroke negatively impacts both patients and their families, who must face multiple changes after the onset of the disease. Family caregivers must face new problems with a possible sense of inadequacy, stress and burden. Our retrospective study aimed to assess the burden of caregivers during the rehabilitation process of patients with Stroke. MATERIAL AND METHOD: This study included patients with a diagnosis of stroke and their caregiver, who attended the Day Hospital of the IRCCS Neurolesi Center "Bonino-Pulejo", Messina, Italy, between January 2018 and October 2019, using electronic recovery system data. The final sample consisted of 30 patients and their caregivers. RESULTS: Significant improvements were observed in patients' cognitive and mood scores, reflecting the efficacy of rehabilitation therapies. Additionally, a correlation emerged between patients' reported anxiety levels and caregivers' reported depression levels, highlighting a dynamic interaction between the emotional states of the two groups. CONCLUSION: The study highlights the intricate interplay between caregiver characteristics, patient outcomes, and family dynamics in the context of caregiving. Targeted interventions aimed at improving family resilience and coping mechanisms are crucial to optimizing the well-being of both caregivers and patients.

Improving Outcomes in People with Spinal Cord Injury: Encouraging Results from a Multidisciplinary Advanced Rehabilitation Pathway.

Spinal cord injury (SCI) consists of damage to any segment of the spinal cord extending to potential harm to nerves in the cauda equina. Rehabilitative efforts for SCI can involve conventional physiotherapy, innovative technologies, as well as cognitive treatment and psychological support. The aim of this study is to evaluate the feasibility of a dedicated, multidisciplinary, and integrated intervention path for SCI, encompassing both conventional and technological interventions, while observing their impact on cognitive, motor, and behavioral outcomes and the overall quality of life for individuals with SCI. Forty-two patients with SCI were included in the analysis utilizing electronic recovery system data. The treatment regimen included multidisciplinary rehabilitation approaches, such as traditional physiotherapy sessions, speech therapy, psychological support, robotic devices, advanced cognitive rehabilitation, and other interventions. Pre-post comparisons showed a significant improvement in lower limb function (Fugl Meyer Assessment-FMA < 0.001), global cognitive functioning (Montreal Cognitive Assessment-MoCA p < 0.001), and perceived quality of life at both a physical and mental level (Short Form-12-SF-12 p < 0.001). Furthermore, we found a significant reduction in depressive state (Beck Depression Inventory-BDI p < 0.001). In addition, we assessed patient satisfaction using the Short Form of the Patient Satisfaction Questionnaire (PSQ), offering insights into the subjective evaluation of the intervention. In conclusion, this retrospective study provides positive results in terms of improvements in motor function, cognitive functions, and quality of life, highlighting the importance of exploring multidisciplinary approaches.

Virtual reality rehabilitation in patients affected by multiple sclerosis: Impact on quality of life and sexual functions.

BACKGROUND: Multiple Sclerosis (MS) can present several neurological symptoms with a progression that often leads to loss of cognitive and physical abilities. Sexual dysfunctions are frequent, although underestimated, MS symptoms significantly affecting the quality of life of these patients. The primary objective of this study was to assess the effectiveness of VR rehabilitation in enhancing the quality of life in individuals with MS. The secondary objective aimed to investigate whether the improvement in quality of life would also lead to enhanced sexual satisfaction and sexual function. MATERIALS AND METHODS: Patients diagnosed with relapsing-remitting and secondary progressive MS and attending from November 2018 to March 2020 the Rehabilitation Laboratory of IRCCS Neurolesi "Bonino Pulejo" in Messina, Italy were enrolled in this study. All patients were randomized into either the control group (CG: 35 patients) that received traditional cognitive rehabilitation (CR) or the experimental group (EG: 35) undergoing VR. RESULTS: The EG showed substantial improvements in various aspects of Multiple Sclerosis Quality of Life (MSQOL) between T0 and T1. Sexual function significantly improved, along with sexual satisfaction. Conversely, the CG achieved significant changes only in overall quality of life. Pearson's correlations highlighted the positive associations between sexual function and satisfaction, as well as with physical and mental well-being, underscoring the importance of improving sexual function as a marker of overall health. DISCUSSION: This study is meant as exploratory as it addresses a fundamental yet overlooked aspect of rehabilitation, i.e., sexual function and sexual satisfaction, which could potentially be enhanced through rehabilitation in a VR environment.

Enhancing the Quality of Life of Patients with Multiple Sclerosis: Promising Results on the Role of Cognitive Tele-Rehabilitation Plus Virtual Reality.

(1) Background: Patients with multiple sclerosis often face obstacles accessing traditional rehabilitation programs, primarily due to mobility limitations. Tele-rehabilitation (TR) is seen as a promising solution to overcome these barriers, though its precise influence on patients' quality of life (QoL) has not been thoroughly investigated. Thus, the aim of the present study was to assess the feasibility of a cognitive TR in a sample of Italian patients with MS. (2) Methods: Thirty-six patients diagnosed with MS, attending the Robotic and Behavioral Neurorehabilitation Unit of the IRCCS "Bonino-Pulejo" Neurolesi Center in Messina, Italy, between October 2019 and March 2020 were enrolled in the study. All patients were randomly assigned, using block randomization with a block size of 2 × 2, to two groups: the control group (CG), composed of 16 patients who received traditional cognitive training, and the experimental group (EG), composed of 20 patients who underwent TR training with a VRRS (virtual reality rehabilitation system). Each patient underwent an assessment before (T0) and immediately after (T1) the rehabilitation treatment, using the Quality of Life-54 Multiple Sclerosis (MSQoL-54). (3) Results: Only in the EG, we observed a statistically significant improvement in the QoL related to mental well-being following the paired T-test (MSQoL p-value < 0.001). Notably, no significant differences were found in the CG (MSQoL p-value of 0.67). (4) Conclusions: Our data suggest that TR training combined with VR has the potential to improve the well-being of individuals with MS.

Do Individuals with Spinal Cord Injury Benefit from Semi-Immersive Virtual Reality Cognitive Training? Preliminary Results from an Exploratory Study on an Underestimated Problem.

A spinal cord injury (SCI) is damage to any part of the spinal cord, caused by traumatic or non-traumatic events. Clinically, SCI is associated with partial or complete loss of motor, sensory, and autonomic functions below the site of injury. However, cognitive alterations in specific domains can also occur. The aim of this study was to evaluate the effects of semi-immersive virtual reality (VR) cognitive training (using the BTS Nirvana, Italy) in promoting global functional recovery in patients with SCI. Forty-two SCI patients were included in this retrospective case-control study, and the analysis was carried out using an electronic data retrieval system. The enrolled patients were divided into two groups with the same demographic and medical characteristics: the control group (CG: 21 patients) participated in traditional therapy, whereas the experimental group (EG: 21 patients) received training using semi-immersive VR. In both groups, there were patients with A- or B-grade impairments according to the American Spinal Injury Association (ASIA) scale. Both study groups underwent the same amount of cognitive training (but using a different type of training: conventional vs. innovative), consisting of three weekly sessions for eight weeks (24 sessions in total), each session lasting approximately sixty minutes, as well as the same amount of physiotherapy. The effect of the two treatments (EG/CG) was significantly different in global cognitive functioning (MOCA: p = 0.001), mood (BDI: p = 0.006), and overall quality of life (SF12 Total: p < 0.001), especially in physical perception (SF12-Physics: p = 0.004). Our results suggest that SCI patients could benefit from cognitive training using semi-immersive VR. Indeed, the integration of cognitive exercises that require movement and provide increased feedback could allow for better motor and cognitive recovery in people with SCI.

Limb apraxia in individuals with multiple sclerosis: Is there a role of semi-immersive virtual reality in treating the Cinderella of neuropsychology?

BACKGROUND: Limb apraxia is an acquired cognitive-motor disorder characterized by spatial and temporal disorganization of limb movements, negatively affecting the quality of life of patients, including those with multiple sclerosis (MS). Although recent studies have shown the potential role of VR in increasing cognitive and motor functions, only a few studies have been carried out on the rehabilitation of upper limb apraxia. Hence, our study aims to evaluate the potential efficacy of VR training to improve upper limb ideomotor apraxia in patients with MS. METHODS: One hundred and six patients, affected by secondary progressive MS, who attended our Robotic and Behavioral Neurorehabilitation Service from March 2019 to February 2020, were enrolled in this study and randomly divided into two groups: the control group (CG: 53 patients) performed traditional therapy whereas the experimental group (EG:53 patients) received training using semi-immersive VR. All patients underwent the same amount of cognitive training, 3 times a week for 8 weeks. They were submitted to a specific neuropsychological assessment before (T0) and after the rehabilitation treatment (T1). RESULTS: The VR training led to a significant improvement in global cognitive functions, with regard to constructive and ideomotor apraxia. On the contrary, the CG achieved significant improvements only in ideomotor apraxia. Moreover, only in the EG, we observed an improvement in the mood at the end of training. CONCLUSION: The present study demonstrates that VR rehabilitation can be an effective tool for the treatment of apraxia, which is a neuropsychological problem often underestimated in MS patients. Further studies with long-term follow-up periods are needed to confirm the effect of this promising approach.

Alzheimer cafè: toward bridging the gap between cure and care in patients with dementia.

BACKGROUND: Alzheimer's disease (AD) is the most common form of degenerative dementia, whose symptoms usually appear in the pre-senile age. In the early stages, patients present social difficulties due to the general cognitive decline in memory, language and executive domains. These problems also affect patients' quality of life, emotions, and mood, leading to social isolation. OBJECTIVE: The aim of this study is to evaluate the effects of Alzheimer's Cafè (AC) on the cognitive and behavioral outcomes of AD patients. METHODS: Twenty patients diagnosed with AD, who attended the Cognitive and Behavioral Rehabilitation Laboratory of the IRCCS Centro Neurolesi 'Bonino-Pulejo' of Messina, Italy, from December 2017 to December 2018, were enrolled in this study. As these patients belonged to the experimental group (EG: n = 20), they received specific cognitive-behavior training using the AC modality. The patients were assessed by a neuropsychological evaluation at the beginning and at the end of the program. Their outcomes were compared to a matched group of patients with neurodegenerative dementia (CG: 20) receiving conventional cognitive training. RESULTS: The pre-post comparisons showed that both CG and EG had a significant improvement in global cognitive functioning (MoCA p < 0.001) and in perceived quality of life (<0.001). However, only in the EG, we observed a significant increase in social functioning (SASS p < 0.00), the perception of mental well-being (SF-12 Mental p < 0.00), and a reduction in the depressive state (GDS p < 0.00). CONCLUSIONS: The present study suggests the importance of AC for patients with AD and the potential effect on psychological and social well-being.

A multidisciplinary advanced approach in central pontine myelinolysis recovery: considerations about a case report.

BACKGROUND AND PURPOSE: Central pontine myelinolysis (CPM) is a solitary, symmetric, demyelination in the central pons. This case study aimed to report the effects of an intensive robotic gait training with Lokomat-Pro on mobility and quality of life in a case of CPM. CASE DESCRIPTION AND INTERVENTION: A 33-year-old female patient with tetraparesis and gait disturbance due to CPM was hospitalized to undergo intensive rehabilitation training for about 2 months. Daily session of Lokomat-Pro and psychotherapy by telemedicine were performed, besides nursing care and occupational and physical therapy. Motor evaluation and quality of life were assessed by using standardized scales. OUTCOMES: The multidisciplinary therapy led to significant improvements both in functional motor outcomes (as per 10-Meter Walk Test, Berg Balance and Tinetti scale) and quality of life. DISCUSSION: Innovation technology, including robotics and telemedicine, may be a valuable tool to improve functional outcomes in patients with severe motor impairment due to chronic CPM.IMPLICATIONS FOR REHABILITATIONA multidisciplinary approach involving robotics plus virtual reality is mandatory to reduce medical and bedridden complications in patients affected by CPM.

Mental Health of Nurses Working in a Judicial Psychiatry Hospital during the COVID-19 Pandemic in Italy: An Online Survey.

The onset of this new pandemic has highlighted the numerous critical issues at the organizational level, which involve both national healthcare and the judicial system. For this reason, nurses working in prisons may exhibit a poor quality of life, mainly related to their high level of work stress. This cross-sectional survey aimed to assess the emotional state of nurses working in the Judicial Psychiatry Hospital of Barcellona PG (Messina, Italy) during the COVID-19 pandemic. Data collection occurred twice: from 1 April to 20 May 2020 (i.e., during the Italian lockdown) and from 15 October to 31 December 2021 (during the second wave). At baseline, the 35 enrolled nurses presented medium to high levels of stress. At T1, they had a reduction in perceived personal achievement (MBI-PR p = 0.01), an increase in emotional exhaustion (MBI-EE p < 0.001), and stress (PSS p = 0.03), as well as anxiety (STAI Y1/Y2 p < 0.001). Most participants underlined the high usability of the online system (SUS: 69.50/SD 19.9). We also found increased stress, anxiety, and burnout risk in nursing staff. The study clearly demonstrates that the first year of the COVID-19 pandemic in Italy caused a worsening of mental health among nurses working in prisons. We believe that monitoring the mental state of healthcare professionals is fundamental to improving their quality of life and healthcare services.

Cutting the First Turf to Heal Post-SSRI Sexual Dysfunction: A Male Retrospective Cohort Study.

Post-SSRI sexual dysfunction (PSSD) is a set of heterogeneous sexual problems, which may arise during the administration of selective serotonin reuptake inhibitors (SSRIs) and persist after their discontinuation. PSSD is a rare clinical entity, and it is commonly associated with non-sexual concerns, including emotional and cognitive problems and poor quality of life. To date, however, no effective treatment is available. The aim of this study was to retrospectively evaluate the potential efficacy of the different treatments used in clinical practice in improving male PSSD. Of the 30 patients referred to our neurobehavioral outpatient clinic from January 2020 to December 2021, 13 Caucasian male patients (mean age 29.53 ± 4.57 years), previously treated with SSRIs, were included in the study. Patients with major depressive disorder and/or psychotic symptoms were excluded a priori to avoid overlapping symptomatology, and potentially reduce the misdiagnosis rate. To treat PSSD, we decided to use drugs positively affecting the brain dopamine/serotonin ratio, such as bupropion and vortioxetine, as well as other compounds. This latter drug is known not to cause or reverse iatrogenic SD. Most patients, after treatment with vortioxetine and/or nutraceuticals, reported a significant improvement in all International Index of Erectile Function-(IIEF-5) domains (p < 0.05) from baseline (T0) to 12-month follow-up (T1). Moreover, the only patient treated with pelvic muscle vibration reached very positive results. Although our data come from a retrospective open-label study with a small sample size, drugs positively modulating the central nervous system serotonin/dopamine ratio, such as vortioxetine, could be used to potentially improve PSSD. Large-sample prospective cohort studies and randomized clinical trials are needed to investigate the real prevalence of this clinical entity and confirm such a promising approach to a potentially debilitating illness.

Emotional Impact of COVID-19 Pandemic on Nursing Students Receiving Distance Learning: An Explorative Study.

Social restrictions have a significant impact on higher education, especially on nursing students. The main goal of our study was to assess the emotional state of nursing students who received e-learning during the second wave of the COVID-19 pandemic. The secondary objective was instead to measure the usability and acceptability of distance learning systems. A cross-sectional survey design was used to assess the psychological effects of the COVID-19 pandemic on 1st-, 2nd-, and 3rd-year undergraduate nursing students attending the University of Messina, Italy, using an anonymous online questionnaire. The data of 522 nursing students were examined. All participants completed the online questionnaire, declaring the good usability of e-learning education (SUS mean 68.53 ds: 16.76). Moreover, we found that high levels of satisfaction in the use of the means of distance learning (based on the SUS score) were positively correlated with low levels of stress, anxiety, depression, and mental distress. In conclusion, the present study provided relevant information on usability and mental distress related to e-learning and use in a sample of nursing students. It was found that students generally found this method to be good for use. Although e-learning can be a valuable and usable teaching tool, the study suggests that students prefer a blended or presence modality, based on their perception of learning. So teaching nursing students in the future could integrate the two ways to enhance learning. Further studies are needed to evaluate this aspect.

Applications of transcranial magnetic stimulation in migraine: evidence from a scoping review.

Transcranial magnetic stimulation (TMS), a non-invasive brain stimulation method, is trying to emerge as a migraine management strategy for both attack treatment and prevention. This scoping review presents 16 among single-pulse (to manage episodic and chronic migraine) and repetitive TMS randomized clinical trials (to manage chronic migraine). The works we reviewed suggest that TMS may be adopted as add-on therapy in those patients who are refractory to pharmacological therapy only with special arrangements for individualized treatment strategies or research. There are still limited clinical research programs and metaanalysis to promote routinely TMS employment, as TMS has been shown either to have no significant effects for any outcome or to be effective for migraine. These diverging conclusions depend on several biasing factors, including the lack of reliable, large, sham-controlled clinical trials, the dyshomogeneity in study designs (including the area of stimulation, the frequency of stimulation, the number of pulses, pulse intensity, and the number of sessions), patient selection criteria (migraine w/o aura, episodic and chronic migraine; TMS contraindication), and the lack of outcomes homogeneity and long-term real-world efficacy data. Therefore, in the future, it will be important to conduct larger randomized trials to confirm TMS usefulness in migraine management (acute attack and prophylactic treatment), identify those patients who may benefit from TMS, maybe independently of pharmacological treatments (i.e., using TMS as an alternative and not only as an add-on treatment). Otherwise, TMS will play a role in treating migraine only with special arrangements for individualized management strategies or research.

Toward Improving Functional Recovery in AIDS-associated Progressive Multifocal Leukoencephalopathy: A Single Case Pilot Study on a Novel Neuromodulation Approach.

Patients with progressive multifocal leukoencephalopathy (PML) in the context of human immunodeficiency virus-acquired immunodeficiency syndrome (HIV-AIDS) show a partial improvement following rehabilitation; however, this improvement is rapidly lost if the patient is not provided with intensive rehabilitation. A 42-year-old patient affected by HIV-AIDS had a clinical worsening within a few months following PML onset, despite being treated with antiretroviral drugs and conventional rehabilitation. He developed severe paraparesis and significant dependency in the activities of daily life. A first cycle of intensive rehabilitation provided the patient with some significant functional outcomes, although he experienced a worsening of the clinical condition after two months of rest, before admission to our rehabilitation unit. We thus sought to evaluate the effects of intensive robot-aided gait training (RAGT) coupled with transcranial direct current stimulation (tDCS). The patient significantly improved when provided with intensive RAGT coupled with tDCS (as per 10-meter Walk Test [10MWT] and 6-minute Walk Test [6MWT]), and the improvement was maintained at three-month follow-up. As this advanced approach was feasible, safe, and potentially effective, this case suggests that patients with PML-HIV require prolonged multidisciplinary rehabilitation treatment. We can speculate that individuals with PML should also be treated with innovative technology to improve their functional outcomes and therefore quality of life.

Embodied cognition in neurodegenerative disorders: What do we know so far? A narrative review focusing on the mirror neuron system and clinical applications.

Embodied cognition is a theoretical perspective that considers every form of human knowledge and cognition "embodied", as they pass through bodily experience. The aim of this narrative review is to investigate the importance of mirror neurons system in EC, as well as the EC role in neurodegenerative diseases. This narrative review shows deep connections between body and mind: body states influence mental functions such as perception and reasoning, while mental states cause changes in the body, especially in neurodegenerative disorders. Indeed, abnormalities in EC were found in dementia, Parkinson's Disease and Amyotrophic Lateral sclerosis, also in the absence of other cognitive deficits, negatively affecting patients' outcomes. Exploiting EC mechanisms for rehabilitation purposes, also using innovation technologies, could be a promising therapeutic way to increase motor and cognitive outcomes in patients affected by different neurological disorders.

Cognitive rehabilitation outcomes in patients with Multiple sclerosis: Preliminary data about the potential role of personality traits.

Background Multiple Sclerosis (MS) can be associated with personality changes. Personality traits affect the cognitive functions, mood, and psychological well-being of people with MS and their families. Objective The aim of this study was to evaluate whether personality traits might be predictors of cognitive recovery in people with MS. Methods. Thirty-one patients with a diagnosis of MS were enrolled in this study. Each participant was evaluated by a neuropsychologist before (T0) and after the end of the rehabilitation treatment (T1). The Five-Factor Model (FFM) has been used to describe the basic personality structure by highlighting five personality traits: extroversion, neuroticism, conscientiousness, agreeableness, and openness. The rehabilitation program included conventional physiotherapy, speech therapy, psychological support, cognitive rehabilitation, and nutritional therapy as well as robotic rehabilitation, advanced cognitive rehabilitation, and virtual reality. Logistic regressions are carried out to measure the changes score between T0 and T1. Results The results showed that patients had significant improvement in cognitive and behavioral functioning. Here, we considered the relationships between the scores of cognitive and emotional/behavioral domains, the five scales of the BFQ, besides the psychiatric symptoms. In particular, the mental quality of life, visuospatial and verbal long-term memory were positively influenced by the agreeableness trait, while depression was negatively affected by this trait. Conclusion Our data suggest that personality traits could influence cognitive and behavioral recovery in patients with MS.

Do patients with multiple sclerosis benefit from semi-immersive virtual reality? A randomized clinical trial on cognitive and motor outcomes.

Multiple sclerosis (MS) is a demyelinating disease of autoimmune originate. A large proportion of patient present with cognitive deficits that negatively affect their quality of life, thus, a proper cognitive rehabilitation is mandatory. The aim of this study is to evaluate the effect of semi-immersive virtual reality training (sVRT) on neuropsychological and motor recovery individuals suffering from MS. We enrolled 60 MS patients, randomized into either the control group (CG: 30) undergoing a conventional cognitive training, or the experimental group (EG: 30), which performed sVRT. Cognitive and motor outcomes were investigated through clinical and neuropsychological scales before (T0) and at the end (T1) of each different training. Only in the EG, we observed a significant improvement in cognitive parameters and motor scores. Our data demonstrate that VR cognitive training could potentiate MS patients' rehabilitation outcome, with positive results on both motor and cognitive performance.

Social cognition in patients with acquired brain lesions: An overview on an under-reported problem.

Social cognition (SC) consists of mental representations of interpersonal relationships, which are used flexibly by the individual to promote functional social behaviors and achieve the goals. SC is a multidimensional construct and is supported by the activity of distributed neural networks in which different cortical and subcortical regions of the brain are involved. The review aims to evaluate the current literature on SC taking into account how it is compromised in acquired brain injury. Studies performed between 2010 and 2019 and fulfilling the selected criteria were searched on PubMed, Scopus, Cochrane and Web of Sciences databases. Impairment of SC is a neglected but common consequence of ABI, often leading to disordered interpersonal functioning and poor regulation of personal behavior with impaired social adaptation and quality of life of both the patient and his/her family. This review supports the idea that SC could have an important role in the management of neurological patients by both clinicians and caregivers.

Toward improving functional recovery in spinal cord injury using robotics: a pilot study focusing on ankle rehabilitation.

BACKGROUND: Conventional physical therapy interventions are strongly recommended to improve ambulation potential and upright mobility in persons with incomplete spinal cord injury (iSCI). Ankle rehabilitation plays a significant role, as it aims to stem drop foot consequences. RESEARCH QUESTION: This pilot study aimed to assess the neurophysiological underpinnings of robot-aided ankle rehabilitation (using a platform robot) compared to conventional physiotherapy and its efficacy in improving gait performance and balance in persons with iSCI. METHODS: Ten individuals with subacute/chronic iSCI (six males and four females, 39 ± 13 years, time since injury 8 ± 4 months, ASIA impairment scale grade C-D) were provided with one-month intensive training for robot-aided ankle rehabilitation (24 sessions, 1 h daily, six times a week). Clinical (10-Meter Walk Test (10MWT), 6-Minute Walk Test (6MWT), and Timed Up and Go test (TUG)), and electrophysiological aftereffects (surface-EMG from tibialis anterior and medial gastrocnemius muscles to estimate muscle activation patterns; and corticomuscular coherence-CMC-to assess functional synchronization between sensorimotor cortex and muscles, i.e. the functional integrity of corticospinal output) were assessed at baseline (PRE) and after the trial completion (POST). The experimental group (EG) data were compared with those coming from a retrospective control group (CG; n = 10) matched for clinical-demographic characteristics, who previously underwent conventional ankle rehabilitation. RESULTS: the EG achieved a greater improvement in balance and gait as compared to the CG (TUG EG from 70 ± 18 to 45 ± 15 s, p = 0.002; CG from 68 ± 21 to 48 ± 18 s, p = 0.01; group-comparison p = 0.001; 10MWT EG from 0.43 ± 0.11 to 0.51 ± 0.09 m/s, p = 0.006; CG from 0.4 ± 0.13 to 0.45 ± 0.12, p = 0.01; group-comparison p = 0.006; 6 MWT EG from 231 ± 13 to 274 ± 15 m, p < 0.001; CG from 236 ± 13 to 262 ± 15 m, p = 0.003; group-comparison p = 0.01). Furthermore, the EG showed a retraining of muscle activation (an increase within proper movements, with a reduction of co-contractions) and CMC (beta frequency increase within proper movements, i.e. in a framework of preserved motor coordination). The improvements in CMC, gait, balance, and muscle activation were not correlated with each other. CONCLUSIONS: Robot-aided ankle rehabilitation improved gait performance by selectively ameliorating CMC, muscle activation patterns, and, lastly, gait balance and speed. Despite CMC, gait, balance, and muscle activation were not correlated, this pilot study suggests that robot-aided ankle rehabilitation may favor a better communication between above-SCI and below-SCI structures. This communication improvement may depend on a more synchronized corticospinal output (as per CMC increase) and a better responsiveness of below-SCI motorneurons to corticospinal output (as per specific and ankle movement focused muscle activation increases at the surface EMG), thus favoring greater recruitment of spinal motor units and, ultimately, improving muscle activation pattern and strength. SIGNIFICANCE: Adopting robot-aided ankle rehabilitation protocols for persons with iSCI in the subacute/chronic phase may allow achieving a clinically significant improvement in gait performance.

Does embodied cognition allow a better management of neurological diseases? A review on the link between cognitive language processing and motor function.

Embodied cognition (EC) refers to the interplay occurring in thinking among individual's sensorimotor capacities (i.e., the ability of the body to respond to its senses with movement), the body itself, and the environment. The aim of the present narrative review is to provide an overall understanding of whether and how motor training could lead to language recovery, consistently with EC theories (action-perception cycle, mirror neuron systems -MNS-, and embodied semantics). We therefore reviewed the works dealing with EC in terms of the link between language processing, mirror neuron system (MNS), and motor function, evaluating the potential clinical implications for better managing neurological deficits. Connections between body and mind were found, as body states influence cognitive functions, such as perception and reasoning, as well as language processing, especially in neurological disorders. In fact, abnormalities in "embodied language" were found in movement disorders and neurodegenerative diseases, negatively affecting patients' rehabilitation outcomes. Understanding the link between language processing and motor outcomes is fundamental in the rehabilitation field, given that EC can be targeted to improve patients' functional recovery and quality of life.
