Role of neurorehabilitation in the recovery of bilateral thalamic stroke related to the artery of Percheron anatomical variant.

Bilateral thalamic stroke is a rare condition, mostly related to the presence of the artery of Percheron (AoP) variant. The clinical presentation of AoP-related strokes is remarkably heterogeneous and often includes cognitive and behavioural alterations. Our report describes the clinical course of an AoP-related bilateral thalamic stroke and highlights the pivotal role of a tailored rehabilitation programme plays in enhancing recovery. A man in his 40s was admitted to the neurology ward due to the abrupt onset of mental status alterations and weakness in his left limbs. The first brain CT scan and subsequent MRI exam revealed a bilateral thalamic stroke and the presence of an AoP anatomical variant. After the first critical phase, the patient's condition became stable, but he still suffered from severe attention, memory and speech deficits. The patient was then transferred to the rehabilitation unit and was subjected to a tailored neurorehabilitation programme that allowed a complete recovery of the symptoms. Neurorehabilitation plays a pivotal role in the patient's recovery and should always be pursued to minimise the residual deficits and, most importantly, to prevent permanent cognitive deficits.

Robot-Assisted Training for Upper Limb in Stroke (ROBOTAS): An Observational, Multicenter Study to Identify Determinants of Efficacy.

BACKGROUND: The loss of arm function is a common and disabling outcome after stroke. Robot-assisted upper limb (UL) training may improve outcomes. The aim of this study was to explore the effect of robot-assisted training using end-effector and exoskeleton robots on UL function following a stroke in real-life clinical practice. METHODS: A total of 105 patients affected by a first-ever supratentorial stroke were enrolled in 18 neurorehabilitation centers and treated with electromechanically assisted arm training as an add-on to conventional therapy. Both interventions provided either an exoskeleton or an end-effector device (as per clinical practice) and consisted of 20 sessions (3/5 times per week; 6-8 weeks). Patients were assessed by validated UL scales at baseline (T0), post-treatment (T1), and at three-month follow-up (T2). The primary outcome was the Fugl-Meyer Assessment for the upper extremity (FMA-UE). RESULTS: FMA-UE improved at T1 by 6 points on average in the end-effector group and 11 points on average in the exoskeleton group (p < 0.0001). Exoskeletons were more effective in the subacute phase, whereas the end-effectors were more effective in the chronic phase (p < 0.0001). CONCLUSIONS: robot-assisted training might help improve UL function in stroke patients as an add-on treatment in both subacute and chronic stages. Pragmatic and highmethodological studies are needed to confirm the showed effectiveness of the exoskeleton and end-effector devices.

Robotic rehabilitation for end-effector device and botulinum toxin in upper limb rehabilitation in chronic post-stroke patients: an integrated rehabilitative approach.

BACKGROUND: Determine the effects of an integrated rehabilitation protocol, including botulinum toxin and conventional rehabilitation exercise plus end-effector (EE) robotic training for functional recovery of the upper limb (UL) compared to training with the robot alone in post-chronic stroke patients with mild to severe spasticity, compared to training with the robot alone. METHODS: In this prospective, observational case-control study, stroke patients were allocated into 2 groups: robot group (RG, patients who underwent robotic treatment with EE) and robot-toxin group (RTG, patients who in addition have carried out the injection of botulinum toxin for UL recovery). All patients were assessed by Fugl-Meyer Assessment (FMA), Motricity Index (MI), modified Ashworth scale (MAS), numeric rating scale (NRS), Box and Block Test (BBT), Frenchay Arm Test (FAT), and Barthel Index (BI) at baseline (T0), T1 (end of treatment), and T2 (3 months of follow-up). RESULTS: Forty-four patients were included and analyzed (21RG; 23RTG). From the analysis between groups, the results suggested how there was a statistically significant difference in favor of RTG, specifically ΔT0-T1 and ΔT0-T2 for B&B p = 0.009 and p = 0.035; ΔT0-T1 and ΔT0-T2 for FAT with p = 0.016 and p = 0.031; ΔT0-T1 for MAS shoulder p = 0.016; ΔT0-T1 and ΔT0-T2 with p = 0.010 and p = 0.005 for MAS elbow; and ΔT0-T1 and ΔT0-T2 with p = 0.001 and p = 0.013 for MAS wrist. CONCLUSION: Our results suggest, in line with the literature, a good efficacy in the reduction of spasticity and in the improvement of the function of the UL, with the reduction of pain, adopting a rehabilitation protocol integrated with BoTN, robot-assisted training, and traditional physiotherapy.

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.
