Combined effects of cerebellar tDCS and task-oriented circuit training in people with multiple sclerosis: A pilot randomized control trial.

BACKGROUND: Balance and mobility impairments are frequent in people with multiple sclerosis, partly due to cerebellar dysfunctions. Task-oriented behavioural approaches were previously shown to promote physical function. The possibility exists that cerebellar transcranial direct current stimulation (ctDCS) applied during training, known to increase the excitability of the brain, can boost rehabilitation effects through modulation of cerebellum-brain inhibition. OBJECTIVE: To test the efficacy of cerebellar ctDCS stimulation combined with motor training on mobility and balance in people with multiple sclerosis. METHODS: 16 subjects were randomly assigned to receive real- or sham-ctDCS and task-oriented training daily over two weeks in a double-blind, randomised clinical pilot trial. Functional mobility, balance, walking performance and quality of life were tested before and after treatment and at two-week follow-up. Effects of cerebellar stimulation on psychological and executive functions were also recorded. RESULTS: Walking performance, balance and quality of life improved for both groups at post-treatment assessment which was maintained at 2-weeks follow up. A two-way ANOVA revealed a significant time effect for balance and walking performance. A significant interaction effect of time-treatment (F = 3.12, df = 2,26; p = 0.03) was found for motor aspects of quality of life assessment in patients who received real-ctDCS. CONCLUSIONS: Task-oriented training improves balance and mobility in people with multiple sclerosis, but ctDCS does not boost motor training effects.

Video game therapy on mobility and dual tasking in multiple sclerosis: study protocol for a randomised controlled trial.

INTRODUCTION: Multiple sclerosis (MS) is one of the major causes of disability in young adults and affects mobility, compromising daily living activities and participation in social life. Cognitive domain is also frequently impaired in people with MS (PwMS), particularly the capacity to perform dual-task activities. Impaired cognitive processing abilities need to be treated, and motor and cognitive aspects need to be considered together. Recently, video game therapy (VGT) has been used in rehabilitation to improve motor outcomes and cognitive processing speed. The aim of this study is to test the efficacy of commercially available VGT on mobility and dual tasking in PwMS compared with standardised balance platform training (BPT). METHODS AND ANALYSIS: This will be a parallel-assignment, double-blinded, randomised control trial. Forty-eight (24 per arm) PwMS with Expanded Disability Status Scale 4-5.5 will be randomly assigned to receive 1 hour training session over 4 weeks (three sessions/week) of either: (1) VGT on commercial video game console to train balance and mobility-related activities or (2) BPT to perform balance, postural stability and weight-shifting exercises with and without visual feedback. The same assessor will evaluate outcome measures at points: before and after the 12 training sessions and at 3 months of follow-up. The primary outcome will be functional mobility, assessed by the Timed Up and Go test. We will also evaluate gait, risk of fall, fatigue and health-related quality of life as well as cognitive and psychological aspects (depression, anxiety and attentional performance) and stability through posturographic evaluation. Dual-tasking assessment will be performed combining posturographic and neuropsychological tests. Data analysis will be performed to compare the efficacy of the two treatments. ETHICS AND DISSEMINATION: Ethical approval have been granted from the local Ethics Committee. Study results will be communicated through high-quality journals and national and international conferences. TRIAL REGISTRATION NUMBER: NCT03353974.

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.

Decompressive craniectomies, facts and fiction: a retrospective analysis of 526 cases.

BACKGROUND: The aim of this article was to review the clinical practice of "bone flap decompression" in Regional Neurosurgical Units with no particular protocol in use. METHODS: From January 2005 to December 2008, a retrospective and multicentre study was conducted on patients who were treated with decompressive craniectomy (DC) in seven departments of neurosurgery in Italy. This study included patients with traumatic brain injury, stroke, aneurysmal subarachnoid haemorrhage and cerebral arteriovenous malformations. Data were retrieved from individual medical records. RESULTS: We identified 526 patients with DC. Age was the most significant predictor factor of survival, together with pupil reactivity, time of decompression and size of the bone flap. The effect of age in predicting survival was so important that in patients over 65 years old we did not find any other significant factor related to survival. In younger patients, the survival rate was much better with a large bone flap (p = 0.01). Unfortunately, 57% of patients were decompressed with a bone flap of less than 12 cm in diameter. This was probably due to the association in 80% of cases between haematoma evacuation and decompression. CONCLUSIONS: The current practice in many centres is different from published papers. Decompression is common over the age of 65 years, is associated with haematoma evacuation and often the bone flaps are inadequate in terms of size.

Randomized study on removable PGE2 vaginal insert versus PGE2 cervical gel for cervical priming and labor induction in low-Bishop-score pregnancy.

BACKGROUND: Dinoprostone vaginal insert has been compared to Dinoprostone cervical gel in few studies, whose cases presented different Bishop scores and gestational ages at admission, and various treatment strategies in control arms. The present study compares the vaginal insert to the cervical gel in patients with low Bishop score at term. METHODS: Prospective multicenter randomized trial, with parity-based randomization. Admission criteria: single pregnancy with Bishop score of 0-4, gestational age of 37-41 weeks, intact membranes, no previous cesarean section, no bleeding or abnormal cardiotocography at admission. RESULTS: Vaginal prostaglandins were required as a second-line induction procedure in 25% of study patients versus 47.1% of controls (p < 0.03, chi2). Study patients experienced shorter induction-to-delivery time (920 +/- 428 versus 1,266 +/- 740 min, p <0,01), with a mean difference of 5 h and 46 min between the groups. Even though patients that received vaginal insert showed a trend of increased incidence of abnormal cardiotocography during labor (12% versus 6.3%) and hyperkinetic labor (11.8% versus 2.1%), the incidence of cesarean sections (21.4% versus 21.6%), cesareans for fetal distress (12.5% versus 11.8%), and umbilical artery pH <7.10 (4.9% versus 2.5%) was comparable between the two groups. CONCLUSIONS: Dinoprostone vaginal insert is more efficient than cervical gel in promoting cervical priming and labor induction in low-Bishop-score patients at term. The vaginal insert placement seems to be safe for the mother and the newborn, although larger studies are required to investigate uterine hyperstimulation incidence.

Doppler predictors of adverse neonatal outcome in the growth restricted fetus at 34 weeks' gestation or beyond.

OBJECTIVE: The study was undertaken to assess whether prenatal Doppler variables can identify cases of fetal growth restriction (FGR) approaching term who are at risk for adverse neonatal outcome. STUDY DESIGN: From a cohort of FGR cases delivered at >or=34 weeks, fetal biometry and pulsatility indices (PI) of fetal arteries obtained less than 2 weeks before delivery were related to adverse neonatal outcome, defined as admission to the neonatal intensive care unit (NICU) for indications other than low birth weight alone. RESULTS: Stepwise regression analysis showed that after controlling for gestational age at delivery and fetal biometry, only the last umbilical artery (UA) PI percentile was significantly predictive of adverse neonatal outcome (odds ratio=1.02, 95% CI 1.01-1.03, P=.02). Receiver operating characteristic curve analysis identified a UA PI at the 65th percentile as optimal predictor of adverse neonatal outcome (sensitivity=60%, false-positive rate=30%). CONCLUSION: In FGR cases delivered at >/=34 weeks' gestation, Doppler PI at the UA independently predicts the likelihood of admission to the NICU for reasons other than low birth weight alone.
