Variations in Health-Related Quality of Life After Stroke: Insights From a Clinical Trial on Arm Rehabilitation With a Long-Term Follow-Up.

Despite rehabilitation, stroke patients continue to have impaired function and reduced health-related quality of life (HRQoL) even in a chronic stage. However, no clear information is available on long-term variations in HRQoL. In this study, we aimed to report the short- and long-term changes in HRQoL in a subacute stroke sample that was enrolled in a clinical trial on arm rehabilitation. Thirty-nine stroke survivors (62% male, mean age 68 years) were assessed using the Stroke Impact Scale Version 2.0 (SIS 2.0) pre and post rehabilitation and at 6 months and 6 years follow-up. Long-term changes in physical function were explored through clinically meaningful changes in the Stroke Impact Scale-16 (SIS-16). After rehabilitation (P < .001), an overall improvement was found in all SIS domains except the memory and thinking, emotions, and communication domains. The baseline SIS-16 score (P < .001), the presence of a sensory deficit, and rehabilitation setting (P < .05) were factors related to the SIS-16 domain scores at the end of rehabilitation and at 6 months follow-up. Patients showed the most deterioration in the mobility (P < .001), strength (P < .003), and hand function (P < .05) domains 6 years after stroke. Stroke severity, male gender, and age ⩾65 years are related with a long-term HRQoL reduction after stroke.

When the practice does not meet the theory: results from an Italian survey on the clinical and pathway management of inpatients with decompressive craniectomy or cranioplasty admitted to rehabilitation.

BACKGROUND: Cranioplasty (CP) is supposed to improve the functional outcome of severe acquired brain injury (sABI) patients with decompressive craniectomy (DC). However, ongoing controversies exist regarding its indications, optimum materials, timing, complications, and relationships with hydrocephalus (HC). For these reasons, an International Consensus Conference (ICC) on CP in traumatic brain injury (TBI) was held in June 2018 to issue some recommendations. AIM: The aims of this study were: to investigate cross-sectionally before the ICC the prevalence of DC/CP in sABI inpatients admitted to neurorehabilitation units in Italy; to assess the perception of Italian clinicians working in the sABI neurorehabilitation settings on the management of inpatients with DC/CP during their rehabilitation stay. DESIGN: Cross-sectional. SETTING AND POPULATION: Physiatrists or neurologists working in 38 Italian rehabilitation centers involved in the care of sABI, giving a pooled sample of 599 inpatients. METHODS: Survey questionnaire consisting of 21 closed-ended questions with multiple-choice answers. Sixteen questions regarded the respondents' opinions and experiences regarding the clinical and management aspects of patients. Survey data were collected via e-mail between April and May 2018. RESULTS: About 1/3 of the 599 inpatients had either a DC (18.9%) or a CP (13.5%). TBI and cerebral hemorrhage were strongly associated with DC/CP, although the association was much stronger for TBI. Significant discrepancies were uncovered between some of the recommendations of the ICC and the corresponding perceptions of the respondents, especially regarding the clinical management of patients (i.e., CP timing). Clear guidelines were perceived as the most crucial factor in improving clinical pathways. CONCLUSIONS: Early collaboration between the neurosurgical and the neurorehabilitation teams is crucial to optimize all clinical and organizational factors, which could expedite CP and minimize the risk of complications, such as infections and HC, to ensure the best possible outcome for DC patients, regardless of the etiology of the sABI. CLINICAL REHABILITATION IMPACT: There may be different attitudes and perceptions, if not controversies, between neurorehabilitation physicians and neurosurgeons regarding the optimal clinical and care pathway management of patients with DC/CP in Italy. Therefore, an Italian Consensus Conference involving all stakeholders on the clinical and management pathways of DC/CP patients admitted to neurorehabilitation is advocated.

Anti-Inflammatory and Cortical Responses after Transcranial Direct Current Stimulation in Disorders of Consciousness: An Exploratory Study.

Disorders of consciousness (DoC) due to severe traumatic brain injury (TBI) are associated with severe disability and an alteration of cortical activation, angiogenesis, and inflammation, which are crucial elements for behavioural recovery. This exploratory study aimed to evaluate anti-inflammatory and cortical responses after transcranial direct current stimulation (tDCS) in traumatic prolonged disorders of consciousness. Ten minimally conscious state (MCS) patients underwent ten sessions of anodal tDCS (five sessions/week, two weeks, 40 min/session) on the primary motor cortex bilaterally. Clinical evaluations were performed using the Coma Recovery Scale-Revised (CRS-R) pre- and post-treatment. In contrast, after single and multiple tDCS sessions, the haemodynamic cortical response was obtained with functional near-infrared spectroscopy (fNIRS). Moreover, angiogenesis (angiopoietin-2, BMP9, endoglin, HbEFG, HGF, IL8, Leptin, PLGF, VEGF-A, and VEGF-C) and inflammation (GM-CSF, IFNg, IP10, MCP1, and TNFα) circulating biomarkers were collected. A significant haemodynamic response was observed after a single tDCS session, with an increased activation from 4.4 (3.1-6.1) to 7.6 (2.9-15.7) a.u. (p = 0.035). After ten tDCS sessions, a significant reduction of angiopoietin-2, VEGF-C, and IP-10 was detected. Moreover, a correlation between behavioural (CRS-R), TNFα (r = 0.89; p = 0.007), and IP10 (r = 0.81; p = 0.014) variation was found. In conclusion, a single tDCS session can increase the cortical activation in MCS patients. Moreover, multiple tDCS sessions showed an anti-inflammatory effect related to behavioural improvement.

The Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment for patients following acquired brain injury: Translation and reliability study.

OBJECTIVE: To develop the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment and to investigate its internal consistency, intra- and inter-rater reliability. DESIGN: Prospective cohort study. SETTING: Rehabilitation department. SUBJECTS: A total of 34 patients with acquired brain injury. MAIN MEASURE: The translation and cultural adaptation process was completed, and the testing procedures of the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment were standardized. Internal consistency was evaluated using Cronbach's alpha index; assessment of intra- and inter-rater reliability was carried out using weighted kappa coefficient. RESULTS: The internal consistency of the tactile sensations and the proprioception items of the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment were generally acceptable to excellent with a range of Cronbach's alpha between 0.73 and 0.97. The intra-rater reliability of the tactile sensations and the proprioception items of the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment were generally good to excellent with a range of weighted kappa coefficients between 0.47 and 1.00. Likewise, the inter-rater reliabilities of these items were predominantly good to excellent with a range of weighted kappa coefficients between 0.42 and 0.92. CONCLUSION: The Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment is a reliable screening tool to evaluate primary somatosensory impairments in patients with acquired brain injury. Further research is necessary to consolidate these results and establish the validity and responsiveness of the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment.

Redefining a minimal rehabilitation assessment protocol for severe acquired brain injuries.

BACKGROUND: The assessment of patients with severe Acquired Brain Injury (sABI) is mandatory in every phase and setting of care, and requires a multidimensional and interdisciplinary approach, to develop the individual rehabilitation project, and monitor long-term functional outcomes. In 2001 the Italian Society of Physical and Rehabilitation Medicine (SIMFER) published the minimal assessment protocol for traumatic sABI, providing a comprehensive, standardized functional assessment based on the International Classification of Functioning, Disability and Health (ICF), 2001. In 2007, a new protocol was published, extended to all sABI patients (PMGCA). In 2019, the SIMFER appointed a working group to provide a revised, updated version: the PMGCA2020. AIM: The purpose of this study was to describe the minimal assessment protocol to be applied at every stage and setting of the care process of patients with sABI. METHODS: The working group, including one neurologist and 11 physiatrists experts in sABI rehabilitation, performed a review of the international recommendations for sABI assessment focusing on the following key words: "sABI assessment," "sABI rehabilitation," "sABI prognostic factors," "sABI rehabilitation assessment," "sABI outcome," in MEDLINE. Revision and integration proposals by each member were written and motivated, discussed and voted. RESULTS: The PMGCA2020 is addressed to sABI adult patients. It investigates the main clinical problems of sABI at any time of the rehabilitation pathway. It includes a demographic/anamnestic section, a clinical/functional assessment section and an outcome measures section following the ICF model of functioning and the model of the construction of the rehabilitation project. CONCLUSIONS: The PMGCA2020 provides an updated tool for the multidimensional rehabilitation assessment of sABI patients, at any stage of the rehabilitation pathway. Further studies will allow the validation of this minimum set of variables paving the way to an assessment standardization of patients with sABI in the rehabilitation settings. CLINICAL REHABILITATION IMPACT: This minimum set of variables, defining patient's functioning and clinical status and outcomes, at every stage and setting of the care process to provide a framework for the standardization of the clinical evaluation of patients with sABI in rehabilitation settings.

Is robot-assisted gait training intensity a determinant of functional recovery early after stroke? A pragmatic observational study of clinical care.

Gait rehabilitation is a critical factor in functional recovery after a stroke. The aim of this pragmatic observational study was to identify the optimal dose and timing of robot-assisted gait training (RAGT) that can lead to a favourable outcome in a sample of subacute stroke survivors. Subacute patients with stroke who underwent a RAGT within a multidisciplinary rehabilitation program were enrolled. A set of clinical (i.e. age, type of stroke and time since stroke) and rehabilitation stay outcomes (length of stay and RAGT number of sessions) were recorded to evaluate their impact on functional outcome measures by functional independence measure (FIM) or functional ambulation category (FAC). We included 236 patients (62.73 ± 11.82 year old); 38.44% were females, and 59.32% were ischaemic stroke patients. Patients that received at least 14 RAGT sessions, had 15.83% more chance to be responders compared to those that receive less sessions (P = 0.006). Similarly, younger patients (≤60 years) were more prone to be responders (+15.1%). Lastly, an early rehabilitation (<6 weeks) was found to be more efficient (+21.09%) in determining responsiveness (P < 0.001). Becoming newly independent for gait, that refers to a FAC score ≥4, was related with age and RAGT sessions (P = 0.001). In conclusion, a younger age (≤60 years), an early rehabilitation (<6 weeks since stroke) and a higher RAGT dose (at least 14 sessions) were related to a favourable outcome in patients with subacute stroke.

Beneficial Effects of Robot-Assisted Gait Training on Functional Recovery in Women after Stroke: A Cohort Study.

Background and Objectives: Robot-assisted gait training (RAGT) could be a rehabilitation option for patients after experiencing a stroke. This study aims to determine the sex-related response to robot-assisted gait training in a cohort of subacute stroke patients considering mixed results previously reported. Materials and Methods: In this study, 236 participants (145 males, 91 females) were admitted to a rehabilitation facility after experiencing a stroke and performed RAGT within a multidisciplinary rehabilitation program. Functional Independence Measure (FIM) and Functional Ambulatory Category (FAC) were assessed at admission and discharge to determine sex-related outcomes. Results: At the baseline, no significant difference among sexes was observed. At the end of rehabilitation, both males and females exhibited significant improvements in FIM (71% of males and 80% of females reaching the MCID cut-off value) and FAC (∆score: men 1.9 ± 1.0; women 2.1 ± 1.1). A more remarkable improvement was observed in women of the whole population during the study, but statistical significance was not reached. When analysing the FAC variations with respect to the total number of RAGT sessions, a more significant improvement was observed in women than men (p = 0.025). Conclusion: In conclusion, among subacute stroke patients, benefits were observed following RAGT during a multidisciplinary rehabilitation program in both sexes. A greater significant recovery for women with an ischemic stroke or concerning the number of sessions attended was also highlighted. The use of gait robotics for female patients may favour a selective functional recovery after stroke.

Telerehabilitation in Italy During the COVID-19 Lockdown: A Feasibility and Acceptability Study.

This study examined the feasibility and acceptability of a telerehabilitation program during the COVID-19 pandemic in a sample of adult patients with physical disabilities. Of the twenty-three patients enrolled, 11 agreed to participate in a video-based telerehabilitation program. Barriers and facilitators to the adoption of telerehabilitation were identified and clinical, demographic, and psychological variables were analysed as predictors of success. Age, cognitive reserve, and resilience were significant predictors of satisfaction with telerehabilitation (p<0.05). The telerehabilitation program was perceived as feasible and was well accepted by patients, despite some technology challenges. However, patients who took advantage of telerehabilitation perceived differences in the quality of service and preferred traditional in-person treatment to service delivery via telerehabilitation.

Motor Cortical Activation Assessment in Progressive Multiple Sclerosis Patients Enrolled in Gait Rehabilitation: A Secondary Analysis of the RAGTIME Trial Assisted by Functional Near-Infrared Spectroscopy.

This study aimed to determine cortical activation responses to two different rehabilitative programs, as measured through functional near-infrared spectroscopy (fNIRS). As a secondary analysis of the RAGTIME trial, we studied 24 patients with progressive multiple sclerosis (MS) and severe disability who were randomized to a regimen of robot-assisted gait training (RAGT) or overground walking (OW). Cortical activation during a treadmill walking task, assessed through fNIRS recordings from the motor and premotor cortexes (M1/PM), was calculated as the area under the curve (AUC) of oxyhemoglobin for each hemisphere and the total area (Tot-OxyAUC). Gait speed, endurance, and balance were also measured, along with five healthy control subjects. At baseline, Tot-OxyAUC during walking was significantly increased in MS patients compared to healthy people and was significantly higher for those with more severe disabilities; it was also inversely correlated with physical performance. After rehabilitation, significant opposite variations in Tot-OxyAUC were observed, with activity levels being increased after OW and decreased after RAGT (+242,080 ± 361,902 and -157,031 ± 172,496 arbitrary units, respectively; p = 0.002), particularly in patients who were trained at a lower speed. Greater reductions in the cortical activation of the more affected hemisphere were significantly related to improvements in gait speed (r = -0.42) and endurance (r = -0.44). Cortical activation, assessed through fNIRS, highlighted the brain activity in response to the type and intensity of rehabilitation.

Redefining a minimal assessment protocol for stroke rehabilitation: the new "Protocollo di Minima per l'ICtus" (PMIC2020).

The use of standardized assessment protocols is strongly recommended to identify patient's needs, outcomes, and predictors of response to specific interventions in Stroke rehabilitation. In 2008, the Italian Society of Physical and Rehabilitation Medicine (SIMFER) published the minimal protocol for the person with stroke ("Protocollo di Minima per l'ICtus" [PMIC]), in reference to the International classification of Functioning, Disability and Health. In 2019, the SIMFER appointed a working group to provide a revised, updated version in line with the most recent literature and suitable for all rehabilitation settings: the PMIC2020. Descriptive study based on the consensus of a panel of experts. The study setting includes all the rehabilitation settings. The population included is represented by stroke survivors with disability. The coordinator of the SIMFER National Stroke Section appointed the working group, including the 8 Stroke Section board members, and 4 more experts (3 physiatrists; 1 neurologist). An extensive revision of the international literature on stroke assessment recommendations was performed; each proposed change from PMIC was written and motivated, discussed and voted. The PMIC2020 is a single form, to be administered at any time of the rehabilitation pathway, including a minimum set of variables, consisting of a demographic/anamnestic section, and a clinical/functional assessment section. Newly introduced tools included measures of malnutrition (BMI<18.5); pain in verbal and non-verbal patients (Numeric Rating Scale-pain, Pain Assessment in Advanced Dementia Scale); neurological impairment (National Institute of Health-Stroke Scale); activity (Modified Barthel Index, Short Physical Performance Battery); and participation (Frenchay Activity Index). The PMIC2020 provides an updated tool for the multidimensional rehabilitation assessment of the stroke patient, at any stage of the rehabilitation pathway, aiming at a shared minimum set of variables defining patient's needs and at defined outcomes across different rehabilitation facilities and settings. The PMIC2020 identifies patient's needs, outcomes, and predictors of response to specific interventions in Stroke rehabilitation and provide ground for a highly needed Stroke Registry.

Telemedicine from research to practice during the pandemic. "Instant paper from the field" on rehabilitation answers to the COVID-19 emergency.

COVID-19 pandemic is creating collateral damage to outpatients, whose rehabilitation services have been disrupted in most of the European countries. Telemedicine has been advocated as a possible solution. This paper reports the contents of the third Italian Society of Physical and Rehabilitation Medicine (SIMFER) webinar on "experiences from the field" COVID-19 impact on rehabilitation ("Covinars"). It provides readily available, first-hand information about the application of telemedicine in rehabilitation. The experiences reported were very different for population (number and health conditions), interventions, professionals, service payment, and technologies used. Commonalities included the pushing need due to the emergency, previous experiences, and a dynamic research and innovation environment. Lights included feasibility, results, reduction of isolation, cost decrease, stimulation to innovation, satisfaction of patients, families, and professionals beyond the starting diffidence. Shadows included that telemedicine can integrate but will never substitute face-to-face rehabilitation base on the encounter among human beings; age, and technology barriers (devices absence, bad connection and human diffidence) have also been reported. Possible issues included privacy and informed consent, payments, cultural difficulties in understanding that telemedicine is a real rehabilitation intervention. There was a final agreement that this experience will be incorporated by participants in their future services: technology is ready, but the real challenge is to change PRM physicians' and patients' habits, while better specific regulation is warranted.

Soluble neural cell adhesion molecule and behavioural recovery in minimally conscious patients undergoing transcranial direct current stimulation.

BACKGROUND: Transcranial direct current stimulation (tDCS) is used for therapeutic purpose in severely brain-injured patients. The relationship between the recovery after tDCS and potential biomarkers in plasma has been limitedly investigated in patients with minimal conscious state (MCS). OBJECTIVE: To investigate soluble neuronal adhesion molecule (sNCAM) plasma levels in relation to tDCS and recovery processes in MCS. METHODS: sNCAM was measured in plasma before (T-1,T0), during (T1) and after (T2, T3) tDCS sessions in eight patients with a post traumatic etiology and at least one year of chronic state. RESULTS: While sNCAM levels were highly correlated overtime, no significant difference was observed in relation to tDCS. An inverse relation was observed between sNCAM levels at baseline and the tDCS long-lasting effects (T-1, r = -0.852, p = 0.007; T0, r = -0.787, p = 0.020). CONCLUSIONS: This exploratory research suggests the sNCAM levels, potentially associated with tDCS outcomes, as a candidate biomarker of neurobiological after-effects in MCS patients.

Bilateral M1 anodal transcranial direct current stimulation in post traumatic chronic minimally conscious state: a pilot EEG-tDCS study.

OBJECTIVE: We tested the preliminary effects of bilateral anodal transcranial direct current stimulation (tDCS) in patients with disorders of consciousness. DESIGN: Open label pilot study. SUBJECTS: Ten chronic (greater than 12 months) patients in a minimally conscious state (MCS) following severe traumatic brain injury. METHODS: The patients received 10 sessions of bilateral M1 anodal tDCS. Behavioural changes were assessed with the Coma Recovery Scale-Revised (CRS-R) before stimulation (T-1, T0), after five sessions (T1), at the end of the stimulation (T2), after two weeks (T3) and after three months (T4). Moreover, an EEG assessment was conducted. RESULTS: Eight out of 10 patients showed new clinical signs of consciousness; specifically, a 2-point CRS-R improvement was detected in the last follow-up (p = 0.004). EEG upper α bandwidth was greater in the parietal site at T1 (p < 0.034). In addition, we found a significant correlation between behavioral and EEG indices at T1 (r =  0.89; p =  0.001). CONCLUSION: This preliminary study presents several limitations (small sample size and no control group). However, it provides important initial data that can be used to design randomized clinical trials testing this novel approach in MCS and to further explore EEG as a neural marker for the effects of tDCS.

Is telemonitoring useful for supporting persons with consciousness disorders and caregivers? A preliminary observational study in a real-life population.

Introduction Preliminary evidences showed that telemedicine may allow a reduction of costs and an enhancement of patients' satisfaction and quality of life (QoL), with the same effectiveness of conventional methods of healthcare delivery. Literature is quite absent in relation to the use of telemedicine for patients with disorders of consciousness (DoC) whose management is delegated almost entirely to the family. In order to promote an alternative setting to manage persons affected by DoC, also supporting their families, a pilot project was designed to test the feasibility of home-care assistance based on a system of telemonitoring. Methods In total, 11 patients were supported by a telemonitoring system via a workstation installed at the patients' homes. All patients underwent a clinical and functional evaluation at enrolment, after two months, after six months and at the end of the project, after 12 months by means of clinical scales (Glasgow Coma Scale, Rancho Los Amigos Levels of Cognitive Functioning Scale, Glasgow Outcome Scale, Disability Rating Scale), while the World Health Organization (WHO) QoL, the Hamilton Depression Rating Scale, the Hamilton Anxiety Rating Scale and a satisfaction score were completed by caregivers. Results Patients' scores at the clinical scales did not show statistically significant differences from T0 to T3. A trend toward the improvement of caregivers' QoL, anxiety and depression, as well as a high degree of satisfaction with regard to the intervention, were reported. The economic evaluation showed an average cost/day for a patient of about €70. Discussion Preliminary data suggest that the use of telemonitoring services in the management of persons affected by DoC is feasible and well accepted by caregivers, with a potential positive effect on their mood and QoL. Therefore, telemonitoring should be considered in the management of DoC patients to favour discharge from acute care and to support families in home care.

Epidemiology and clinical outcomes in a multicentre regional cohort of patients with severe acquired brain injury.

PURPOSE: To evaluate epidemiological and clinical data on patients with severe acquired brain injury (sABI) admitted to rehabilitation units in the first 6 years since the inception of a regional register (2005-2010) in the Emilia-Romagna region (Italy). METHOD: Retrospective multicentre study of a regional cohort using data from an online regional register (Gravi Cerebrolesioni Emilia-Romagna - GRACER). The study included 318 patients who suffered sABI (defined by Glasgow Coma Scale score ≤8 recorded in the initial 24 h following injury), who were admitted to and subsequently discharged from rehabilitation units. Physical and cognitive functions were evaluated at admission and discharge. Other data recorded included aetiology, presence of secondary conditions and need for specific medical support. RESULTS: Three-quarters of patients displayed improvements in physical and/or cognitive function at discharge from rehabilitation units, with 71.4% of patients returning home. Better outcomes at discharge were associated in particular with younger age, traumatic brain injury (versus non-traumatic), or absence of tracheostomy at admission. CONCLUSION: The GRACER register is a useful tool for the assessment of epidemiological and clinical information on sABI patients. In light of the positive impact on patient outcomes, rehabilitation in specialised units is highly encouraged and should occur as soon as possible. Implications for Rehabilitation There is a need for more epidemiological and clinical data associated with severe acquired brain injury, particular regarding those of non-traumatic origin. In a retrospective multicentre study of a regional cohort using data from an online regional register in Italy (GRACER), more than three-quarters of patients displayed improvements in physical and/or cognitive function at discharge from the rehabilitation units. Better outcomes at discharge were associated in particular with younger age, traumatic brain injury (versus non-traumatic) or absence of tracheostomy at admission. Admission to a specialised rehabilitation unit is highly encouraged for patients with severe acquired brain injury, and should occur as soon as possible. Policy-makers and service planners should continue to develop strategies and allocate adequate resources for rehabilitation services due to their positive impact on patient outcomes. In particular, patients with conditions associated with increased likelihood of poor outcomes may require special attention during rehabilitation to improve outcomes at discharge.

Early rehabilitation for severe acquired brain injury in intensive care unit: multicenter observational study.

BACKGROUND: The increased survival after a severe acquired brain injury (sABI) raise the problem of making most effective the treatments in Intensive Care Unit (ICU)/Neurointensive Care Unit (NICU), also integrating rehabilitation care. Despite previous studies reported that early mobilization in ICU was effective in preventing complications and reducing hospital stay, few studies addressed the rehabilitative management of sABI patients in ICU/NICU. AIM: To collect clinical and functional data about the early rehabilitative management of sABI patients during ICU/NICU stay. DESIGN: Prospective, observational, multicenter study. SETTING: Fourteen facilities supplied by intensive neurorehabilitation units and ICU/NICUs. POPULATION: Consecutive sABI patients admitted to ICU/NICU. METHODS: Patients were evaluated at admission and then every 3-5 days. Clinical, functional and rehabilitative data, including Glasgow Coma Scale (GCS), Disability Rating Scale (DRS), The Rancho Los Amigos Levels of Cognitive Functioning Scale (LCF), Early Rehabilitation Barthel Index (ERBI), Glasgow Outcome scale (GOS) and Functional Independence Measure (FIM) were collected. RESULTS: One hundred and two patients (F/M 44/58) were enrolled. The mean duration of ICU stay was 24.7±13.9 days and the first rehabilitative evaluation occurred after 8.7±8.8 days. Regular postural changes and multijoint mobilization were prescribed in 63.7% and 64.7% cases, respectively. The mean session duration was 38±11.5 minutes. Swallowing evaluation was performed in 14.7% patients, psychological support was provided to 12.7% of patients' caregivers, while 17.6% received a psycho-educational intervention, and 28.4% were involved in interdisciplinary team meetings. The main discharge destinations were Severe Acquired Brain Injury rehabilitation units for 43.7%, intensive neurorehabilitation units for 20.7%. CONCLUSIONS: Data showed that early rehabilitation was not diffusely performed in sABI subjects in ICU/NICU and rehabilitative interventions were variable; one-third of subjects were not referred to dedicated rehabilitation unit at discharge. CLINICAL REHABILITATION IMPACT: The study stresses the need to spread and implement a rehabilitative culture also for critical ill patients due to neurological diseases.

Predictive value of circulating insulin-like growth factor I levels in ischemic stroke outcome.

CONTEXT: Cerebrovascular disease is highly prevalent in the general population, frequently leading to permanent invalidity and reduced quality of life. IGF-I is recognized as an important neuroprotective factor against cerebral hypoxic insult. OBJECTIVE: The objective of the study was to evaluate pituitary function, in particular GH-IGF-I axis, in adult patients receiving rehabilitation after an ischemic stroke. SUBJECTS AND METHODS: We studied 42 patients (12 females; age range, 50-88 yr) during rehabilitation after stroke, evaluating the relationship between the GH-IGF-I axis and the severity (National Institutes of Health stroke scale) and outcome [Rancho Los Amigos Scale of Cognitive Functioning (LCFS); Functional Independence Measure (FIM); modified Ranking Scale] from stroke. RESULTS: GH deficiency was demonstrated in five patients (11.9%). Peak GH after GHRH + arginine test and IGF-I levels did not correlate with severity of stroke. IGF-I was positively correlated with LCFS (r = 0.305, P < 0.05) and the difference between FIM on admission and at discharge from rehabilitation (DeltaFIM; r = 0.361, P < 0.02). Outcome indexes (LCFS, FIM at discharge, DeltaFIM) and occurrence of favorable outcome (modified Ranking Scale 0-1) were significantly (P < 0.05) higher in patients with IGF-I levels 161.8 mug/dl or greater (50th percentile of the patient distribution). LH-FSH deficiency (three cases), ACTH deficiency (one case), and hyperprolactinemia (two cases) were detected. One patient had primary hypogonadism, and six males had low testosterone with normal LH and FSH levels. By multivariate analysis, IGF-I level was the main significant predictor of DeltaFIM and LCFS. CONCLUSIONS: Ischemic stroke may be associated with pituitary dysfunction, particularly GH and gonadotropin deficiencies. The higher IGF-I levels observed in patients with better outcome suggest a possible neuroprotective role of IGF-I. Circulating IGF-I may predict functional performance during rehabilitation and ischemic stroke outcome.
