Abstract
The study aimed to determine longitudinal trajectories of cognitive function during the first year after stroke. The Montreal Cognitive Assessment (MoCA) was used to screen cognitive function at 36-48 h, 3-months, and 12-months post-stroke. Individuals who shared similar trajectories were classified by applying the group-based trajectory models. Data from 94 patients were included in the analysis. Three cognitive functioning groups were identified by the trajectory models: high [14 patients (15%)], medium [58 (62%)] and low [22 (23%)]. For the high and medium groups, cognitive function improved at 12 months, but this did not occur in the low group. After age, sex and education matching to the normative MoCA from the Swedish population, 52 patients (55%) were found to be cognitively impaired at baseline, and few patients had recovered at 12 months. The impact on memory differs between cognitive functioning groups, whereas the impact on activities of daily living was not different. Patients with the poorest cognitive function did not improve at one-year poststroke and were prone to severe memory problems. These findings may help to increase focus on long-term rehabilitation plans for those patients, and more accurately assess their needs and difficulties experienced in daily living.

Abstract
Several studies have demonstrated that the dynamic factor at the mobile segment affects the severity of myelopathy in patients with cervical ossification of the posterior longitudinal ligament (C-OPLL), and posterior decompression supplemented with posterior instrumented fusion at the mobile segment provides good neurological improvement. However, there have been few reports of changes in range of motion at the mobile segment (segmental ROM) after laminoplasty (LP). The aim of this study was thus to retrospectively investigate changes in segmental ROM after LP and the impacts of these changes on neurological improvement in patients with C-OPLL.A total of 51 consecutive patients who underwent LP for C-OPLL since May 2010 and were followed for at least 2 years after surgery were included in this study. Neurological status was assessed using the Japanese Orthopaedic Association (JOA) score before surgery and at 2-year follow-up. Segmental ROM at the responsible level for myelopathy was measured preoperatively and at 2-year follow-up using lateral flexion-extension radiographs of the cervical spine.The mean JOA score improved significantly from 10.7 points preoperatively to 13.5 points at 2 years after surgery (mean recovery rate, 45.0%). The mean segmental ROM decreased significantly from 6.5 degrees before surgery to 3.2 degrees at 2 years after surgery. In the good clinical outcome group (recovery rate of the JOA score ≥50%; n = 22), the mean segmental ROM decreased significantly from 5.8 degrees preoperatively to 3.0 degrees postoperatively. It also decreased significantly from 7.1 degrees to 3.4 degrees in the poor clinical outcome group (recovery rate of the JOA score <50%; n = 29).This study showed that segmental ROM was stabilized after LP in most patients with C-OPLL. Neither preoperative nor postoperative segmental ROM showed significant differences between the good and poor clinical outcome groups and neither a postoperative increase nor decrease of segmental ROM significantly affected the recovery rate of the JOA score.

Abstract
ABSTRACT Metabolic acidosis is observed in 98% of patients with out-of-hospital cardiac arrest (OHCA). The longer the no-flow or low-flow duration, the more severe is the acidosis in these patients. This study explored whether blood pH in early stages of advanced life support (ALS) was an independent predictor of neurological prognosis in patients with OHCA.We retrospectively enrolled patients with OHCA from January 2012 to June 2018 in a single-medical tertiary hospital in Taiwan. Patients with OHCA whose blood gas analyses within 5 minutes after receiving ALS at the emergency department (ED) were enrolled. Patients younger than 20 years old, with cardiac arrest resulting from traumatic or circumstantial causes, with return of spontaneous circulation (ROSC) before ED arrival, lacking record of initial blood gas analysis, and with do-not-resuscitate orders were excluded. The primary outcome of this study was neurological status at hospital discharge.In total, 2034 patients with OHCA were enrolled. The majority were male (61.89%), and the average age was 67.8 ± 17.0 years. Witnessed OHCA was noted in 571 cases, cardiopulmonary resuscitation was performed before paramedic arrival in 512 (25.2%) cases, and a shockable rhythm was observed in 269 (13.2%). Blood pH from initial blood gas analysis remained an independent predictor of neurological outcome after multivariate regression.Blood pH at early stages of ALS was an independent prognostic factor of post-OHCA neurological outcome. Blood gas analysis on arrival at the ED may provide additional information about the prognosis of patients with OHCA.

Abstract
BACKGROUND Kawasaki disease (KD) is an acute, self-limiting systemic vasculitis that predominately affects children. Neurological involvement is a known complication of KD, however, its association with KD severity remains elusive. We aimed to systematically describe the general manifestations of neurological involvement in KD, determine whether neurological involvement is a marker of disease severity in patients with KD, and assess the relationship of such involvement with intravenous immunoglobulin (IVIG) resistance and coronary artery lesions (CALs). METHODS We retrospectively reviewed data from 1582 patients with KD between January 2013 and December 2017. Profiles of patients with neurological symptoms (group A, n = 80) were compared to those of gender- and admission date-matched patients without neurological involvement (group B, n = 512). Multivariate logistic regression analyses were performed to determine whether neurological involvement was significantly associated with IVIG resistance. RESULTS Neurological involvement was observed in 5.1% (80/1582) of patients with KD. The neurological manifestations were diffuse, presenting as headache (13/80, 16.3%), convulsions (14/80, 17.5%), somnolence (40/80, 50.1%), extreme irritability (21/80, 26.3%), signs of meningeal irritation (15/80, 18.8%), bulging fontanelles (7/80, 8.8%), and facial palsy (1/80, 1.3%). Neurological symptoms represented the initial and/or predominant manifestation in 47.5% (38/80) of patients with KD. The incidence of IVIG resistance and levels of inflammatory markers were higher in group A than in group B. However, neurological involvement was not an independent risk factor for IVIG resistance or CALs. CONCLUSION Rates of neurological involvement were relatively low in patients with KD. Neurological involvement was associated with an increased risk of IVIG resistance and severe inflammatory burden. Our results highlight the need for pediatricians to recognize KD with neurological involvement and the importance of standard IVIG therapy. TRIAL REGISTRATION Retrospectively registered.

Abstract
BACKGROUND The early identification of cerebral palsy (CP) in the primary care context is often problematic and referral for diagnosis often delayed. This study aimed to identify clinical features associated with the early detection of CP that can be used by the primary care provider. METHODS We performed a scoping review by searching six electronic databases. We included English language articles that addressed the diagnosis of CP and/or its differential diagnosis in children and ways of detecting CP before the diagnosis is established (i.e., early clinical signs of CP) via (1) questions on the patient's clinical history, (2) developmental screening and/or health questionnaires, or (3) physical or neurological examination. RESULTS Included studies (n = 41; 27 overview studies and 14 original studies) were grouped into the three themes. Most of the overview articles relied on expert opinion, and all original studies included patients at high risk of developing CP. The most commonly identified features from each theme were early hand preference on clinical history, delayed or absent achievement of motor developmental milestones on developmental screening, and persistent primitive reflexes on neurological examination. CONCLUSIONS Overall, the literature on the early observable clinical signs that should prompt referral for investigation of possible CP in the specific context of well-baby care surveillance was sparse and inconsistent. Further research should focus on evaluating the contribution of readily identifiable clinical features.

Abstract
INTRODUCTION The national protocol of genetic counselling and pre-symptomatic testing for late-onset neurological diseases began in Portugal in 1995. Initially, it was accessible only to adults at-risk for Machado-Joseph disease, but was later extended to other hereditary ataxias, to Huntington's disease and to familial amyloid polyneuropathy caused by Val30Met mutation at the transthyretin gene. The aim of this study was to describe the profile of the population seeking pre-symptomatic testing, while also reflecting on the experience of conducting the protocol of multidisciplinary sessions since 1996. MATERIAL AND METHODS We conducted a retrospective study and collected data from clinical records of consultands who requested pre-symptomatic testing at our centre in Porto (Portugal) during the first twenty years of practice (1996 - 2015). RESULTS A total of 1446 records were reviewed. The most common reason for testing was to reduce uncertainty (41.7%). The rate of withdrawals before results disclosure was lower (16%) than reported in other international experiences with pre-symptomatic testing, while 45% of the consultands dropped out the protocol after learning the test results (73.5% of them were non-carriers). As far as the mutation carriers were concerned, 29.6% adhered to the protocol a year after test disclosure. Consultands that had learned about presymptomatic testing through healthcare professionals tended to adhere more to pre-symptomatic testing consultations. DISCUSSION The profile of Portuguese consultands at risk for late-onset neurological diseases is similar to those reported in other international programs. The largest group in this data set was the one comprising the subjects at risk for familial amyloid polyneuropathy caused by Val30Met mutation at the transthyretin gene, and it is likely that therapeutic options for this condition may have influenced this result. Adherence to pre-symptomatic testing may change in the future since effective therapies are available (or given the fact that people think effective treatments are imminent). CONCLUSION This study reflects the first comprehensive description of a Portuguese experience with pre-symptomatic testing for late onset neurological diseases. The development of innovative approaches to improve the consultands' experience with pre-symptomatic testing and their engagement in genetic departments is still a challenge in Portuguese genetics healthcare departments. A better coordination among primary care and genetics healthcare services is needed.

Abstract
Thoracolumbar disc herniation (TLDH) is a rare and progressively disabling disorder; surgical procedures predispose the subjects to high incidence of complications including recurrence, neurological aggravation, and adjacent segment degeneration.Ten patients with TLDH underwent posterior approach operation in our institution from January, 2006 to December, 2015. The mean preoperative duration of clinical symptoms was 16.5 months. The clinical data including operative time, blood loss, and hospitalization duration were investigated. Furthermore, pre and postoperative neurological status was evaluated by the modified Japanese Orthopedic Association (JOA) scoring system and pain by visual analog scale (VAS) scoring system.The mean operative time was 176.50 ± 20.55 minutes, the mean blood loss was 435.00 ± 89.58 mL, and the mean hospitalization length was 13.30 ± 2.97 days. All patients were followed with a mean period of 35.1 months. The mean JOA score of all patients before operation, at discharge, 3 months after operation, and at last follow-up was 6.50 ± 1.28, 7.60 ± 1.22, 8.90 ± 0.99, and 9.00 ± 0.92, respectively. The differences between the pre and postoperative JOA and VAS scores were significant (P < .05). However, the differences of JOA and VAS scores at postoperative 3 months and final follow-up were not statistically significant.Posterior approach operation is an ideal surgical technique for treatment of TLDH; the operative time, blood loss, hospitalization duration, and symptomatic improvement are favorable.

Abstract
OBJECTIVE The aim of this study was to evaluate whether monitoring of acute carbon monoxide-poisoned (COP) patients by means of quantitative Romberg's test (QR-test) during a hyperbaric oxygen (HBO₂) therapy regimen could be a useful supplement in the evaluation of neurological status. METHODS We conducted a retrospective study (2000-2014) in which we evaluated data containing quantitative sway measurements of acute COP patients (n = 58) treated in an HBO₂ regimen. Each patient was tested using QR-test before and after each HBO₂ treatment. Data were analyzed using linear mixed models (LMM). In each LMM, sway prior to HBO₂ therapy was set as the fixed effect and change in sway after HBO₂ therapy was set as the response variable. Patient, treatment number, weight and age were set as random effects for all LMMs. RESULTS From the LMMs we found that larger values of sway prior to HBO₂ produced a negative change in sway. We found no correlation between CO level and sway (P=0.1028; P=0.8764; P=0.4749; P=0.5883). Results showed that loss of visual input caused a significant increase in mean sway (P=0.028) and sway velocity (P⟨0.0001). CONCLUSIONS The Quantitative Romberg's test is a fast, useful supplement to neurological evaluation and a potential valuable tool for monitoring postural stability during the course of treatment in acute COP patients.

Abstract
BACKGROUND Despite multiple risk factors for neurodevelopmental vulnerability, few studies have assessed neurodevelopmental performance of Australian Aboriginal children. An important risk factor for neurodevelopmental vulnerability is prenatal alcohol exposure (PAE), which places children at risk for Fetal Alcohol Spectrum Disorder (FASD). AIMS This study assesses neurodevelopment outcomes in a population of Australian Aboriginal children with and without PAE. METHODS AND PROCEDURES Children born in 2002/2003, and living in the Fitzroy Valley, Western Australia between April 2010 and November 2011, were eligible (N=134). Sociodemographic and antenatal data, including PAE, were collected by interview with 127/134 (95%) consenting parents/caregivers. Maternal/child medical records were reviewed. Neurodevelopment was assessed by clinicians blinded to PAE in 108/134 (81%) children and diagnoses on the FASD spectrum were assigned. OUTCOMES AND RESULTS Neurodevelopmental disorder was documented in 34/108 children (314.8 per 1000). Any diagnosis on the FASD spectrum was made in 21/108 (194.4 per 1000) children (95% CI=131.0-279.0). CONCLUSIONS AND IMPLICATIONS Neurodevelopmental impairment with or without PAE is highly prevalent among children in the Fitzroy Valley. Rates of diagnoses on the FASD spectrum are among the highest worldwide. Early intervention services are needed to support developmentally vulnerable children in remote communities.

Abstract
INTRODUCTION Although pneumonia is a major complication after acute ischaemic stroke (AIS), pneumonia prediction scores have not been extensively validated. This study aimed to compare the discrimination performance of 5 pneumonia prediction scores in AIS patients. MATERIALS AND METHODS We retrospectively reviewed all consecutive adult AIS patients whom presented to our emergency department within 4.5 hours of symptom-onset between January 2012 and February 2015. Diagnosis had to be made by a neurologist and infarcts confirmed by neuroimaging. We excluded patients with pneumonia on presentation. Pneumonia predictors were based on the 5 prediction scoring models: Kwon's score, Chumbler's score, Acute Ischaemic Stroke-Associated Pneumonia Score (AIS-APS), A2DS2 score and ISAN score. The definition of stroke-associated pneumonia was based on the criteria by the Pneumonia in Stroke Consensus Group. Analysis using area under receiver operating characteristics curve (AUROC) was performed. RESULTS Forty (5.5%) out of 731 patients analysed had stroke-associated pneumonia (SAP). A2DS2 score had the highest discrimination capacity (AUROC 0.88; 95% CI, 0.84 to 0.92), followed by AIS-APS (AUROC 0.87; 95% CI, 0.83 to 0.91), Kwon's score (AUROC 0.86; 95% CI, 0.82 to 0.92), Prestroke Independence, Sex, Age and National Institutes of Health Stroke Scale (ISAN) score (AUROC 0.85; 95% CI, 0.80 to 0.90) and Chumbler's score (AUROC 0.79; 95% CI, 0.74 to 0.84). However, there was no statistical difference of discrimination capacity among A2DS2 score, AIS-APS and Kwon's score. CONCLUSION A2DS2 , AIS-APS and Kwon's scores performed comparably in discriminating SAP in AIS patients.

Abstract
BACKGROUND The pathogenesis and progression of branch atheromatous disease (BAD), which differs from lipohyalinotic degeneration (LD), remains controversial. Few studies have investigated the lipid indices and glycometabolism status factors for BAD in first-ever penetrating artery infarction (PAI). METHODS We retrospectively examined acute stroke patients with PAI admitted within 3 days after stroke. All patients underwent diffusion weight magnetic resonance imaging (DWI) and magnetic resonance angiography (MRA) and/or computed tomography angiography (CTA). Progression was defined as an increase by 2 point or higher in the National Institutes of Health Stroke Scale score. The characteristics, clinical data were statistically analyzed. RESULTS BAD and LD were diagnosed in 142 (57%) and 107 (43%) patients, respectively. Patients with BAD had higher low-density lipoprotein cholesterol (LDL-C) compared with those with LD (p = .013). Elevated LDL-C was related to early neurological deterioration in patients with BAD (p = .045). The percentage of lenticulostriate arterial (LSA) infarction was greater than that of the pontine penetrating arterial (PPA) infarction in acute PAI (75.1% vs. 24.9%; p < .001). PPA infarction was more prevalent in the BAD group compared with the LD group (34.5% vs. 12.1%, p < .001). The PPA infarction had older age at onset and higher HbA1c concentrations than those with the LSA infarction (p = .014, p = .036 respectively) in the BAD and LD patients, respectively. CONCLUSION LDL-C may be associated with both the pathogenesis and progression of intracranial BAD. The LSA infarction was the most frequently subtypes in PAI. Age at onset and HbA1c seem to be closely associated with the PPA infarction of first-ever PAI.

Abstract
To investigate the clinical characteristics and short-term prognosis of elderly patients with Guillain-Barré syndrome (GBS).We retrospectively analyzed the clinical data of adult GBS. According to the age, the enrolled subjects were divided into 2 groups, that is, patients ≥60 years (elderly group) and those aged 18 to 59 years (nonelderly group). The clinical characteristics and short-term prognosis of the patients in the 2 groups were compared.In total, 535 patients were enrolled. There were 67 patients fell into the elderly group with a mean age of 69 years old; while 468 patients fell into the nonelderly group with a mean age of 39 years old. We found that the elderly patients had significantly lower incidence of antecedent infections (49.3% vs 66.2%, P < 0.01). The time from onset to admission (5 vs 4 days, P < 0.05) and time from onset to nadir (7 vs 6 days, P < 0.05) were significantly longer in the elderly patients. It was noteworthy that more elderly patients were found with lymphocytopenia (55.4% vs 37.3%, P < 0.01), hyponatremia (25.0% vs 10.2%, P < 0.01), hypoalbuminemia (9.0% vs 2.6%, P < 0.05), and hyperglycemia (34.3% vs 15.2%, P < 0.01). Importantly, the elderly patients had longer duration of hospitalization (17 vs 14 days, P < 0.05), higher incidence of pneumonia (29.9% vs 18.8%, P < 0.05), and poorer short-term prognosis (58.2% vs 42.7%, P < 0.05). In patients with severe GBS, no significant differences were observed in disease severity, treatment modality, incidence of pneumonia, and duration of hospitalization between the 2 groups. However, more patients in the elderly group showed poor short-term prognosis (84.1% vs 63.8%, P < 0.01). Further, old age (≥60 years) (OR = 2.906, 95% CI: 1.174-7.194, P < 0.05) and lower Medical Research Council (MRC) score at nadir (OR = 0.948, 95% CI: 0.927-0.969, P < 0.01) were risk factors for poor short-term prognosis in severe GBS patients.The clinical characteristics and short-term prognosis of elderly patients with GBS are distinct from nonelderly adults. Old age (≥60 years) and lower nadir MRC score serve as predictor for poor short-term prognosis in severe GBS patients.

Abstract
OBJECTIVE: To investigate the extent of within-system reliability and between-system correlation for the “Sydney” and “Sunnybrook” systems of grading facial nerve paralysis, and to examine the interobserver reliability and agreement of the “House Brackmann” grading system. STUDY DESIGN: A fixed-effects reliability study in which 6 otolaryngologists viewed videotapes of patients with facial nerve paralysis. SETTING: University and medical Centers. PATIENTS: Patients with unilateral lower motor neurone facial nerve dysfunction greater than 1 year after onset, none of whom had undergone surgical reanimation procedures. INTERVENTION: Twenty-one patients with facial nerve paralysis were videotaped while they performed a protocol of facial movements. Six otolaryngologists viewed the videotapes and scored them with the Sydney and Sunnybrook systems, and then gave a House Brackmann grade. MAIN OUTCOME MEASURE: The 3 systems of grading facial nerve paralysis were evaluated and compared with the use of intraclass correlation coefficients, Pearson's weighted kappa, and percentage exact agreement values. RESULTS: The Sydney and the Sunnybrook systems had good intrasystem reliability and high intersystem association for the assessment of voluntary movement. Grading of synkinesis was found to have low reliability both within and between systems. The House Brackmann system had substantial reliability as shown by weighted kappa but had a percentage exact agreement of 44%. CONCLUSIONS: For clinical grading of voluntary movement, there is good correlation between ratings given on the Sydney and Sunnybrook systems, and within each system there is good reliability. The assessment of synkinesis was far less reliable within, and less related between, systems. Although the reliability of the House Brackmann system was found to be high, examination of individual grades revealed some wide variation between trained observers.

Abstract
Although functional neurological symptoms are often very disabling there is limited information on outcome after treatment. Here we prospectively assessed the short- and long-term efficacy of an inpatient multidisciplinary programme for patients with FNS. We also sought to determine predictors of good outcome by assessing the responsiveness of different scales administered at admission, discharge and follow-up. Sixty-six consecutive patients were included. Assessments at admission, discharge and at 1 year follow-up (55%) included: the Health of the Nation Outcome Scale, the Hospital Anxiety and Depression Scale, the Patient Health Questionnaire-15, the Revised Illness Perception Questionnaire, the Common Neurological Symptom Questionnaire, the Fear Questionnaire and the Canadian Occupational Performance Measure. At discharge and at 1 year follow-up patients were also asked to complete five-point self-rated scales of improvement. There were significant improvements in clinician-rated mental health and functional ability. In addition, patients reported that their levels of mood and anxiety had improved and that they were less bothered by somatic symptoms in general and neurological symptoms in particular. Two-thirds of patients rated their general health such as "better" or "much better" at discharge and this improvement was maintained over the following year. Change in HoNOS score was the only measure that successfully predicted patient-rated improvement. Our data suggest that a specialized multidisciplinary inpatient programme for FNS can provide long-lasting benefits in the majority of patients. Good outcome at discharge was exclusively predicted by improvement in the HoNOS which continued to improve over the 1 year following discharge.

Abstract
The Mastication Observation and Evaluation (MOE) instrument was developed to allow objective assessment of a child's mastication process. It contains 14 items and was developed over three Delphi rounds. The present study concerns the further development of the MOE using the COSMIN (Consensus based Standard for the Selection of Measurement Instruments) and investigated the instrument's internal consistency, inter-observer reliability, construct validity and floor and ceiling effects. Consumption of three bites of bread and biscuit was evaluated using the MOE. Data of 59 healthy children (6-48 mths) and 38 children (bread) and 37 children (biscuit) with cerebral palsy (24-72 mths) were used. Four items were excluded before analysis due to zero variance. Principal Components Analysis showed one factor with 8 items. Internal consistency was >0.70 (Chronbach's alpha) for both food consistencies and for both groups of children. Inter-observer reliability varied from 0.51 to 0.98 (weighted Gwet's agreement coefficient). The total MOE scores for both groups showed normal distribution for the population. There were no floor or ceiling effects. The revised MOE now contains 8 items that (a) have a consistent concept for mastication and can be scored on a 4-point scale with sufficient reliability and (b) are sensitive to stages of chewing development in young children. The removed items are retained as part of a criterion referenced list within the MOE.

Abstract
The aim of this study was (a) to develop an assessment tool (the Democritos Movement Screening Tool for Preschool Children - DEMOST-PRE), designed to provide preschool educators, clinicians and researchers with information about assessment and screening of the motor proficiency of children aged 4-6 years, as well as the development and control of movement programmes and (b) to assess its factorial validity. First, tool's content and face validity were established and its final structure was determined. Then, the DEMOST-PRE was administered to 435 children (197 girls) aged 48-71 months (M=60.48 months, SD=6.98). The factor analysis conducted revealed two distinct components. Present evidence combined with the DEMOST-PRE administrative traits make it promising for preschool aged children's assessment.

Abstract
This paper reports on a study that aimed to assess the inter-rater agreement of observable neurological signs in the upper and lower limbs (eg inspection, gait, cerebellar tests and coordination) and elicitable signs (eg tone, strength, reflexes and sensation). Thirty patients were examined by two neurology doctors, at least one of whom was a consultant. The doctors' findings were recorded on a standardised pro forma. Inter-rater agreement was assessed using the kappa (κ) statistic, which is chance corrected. There was significantly better agreement between the two doctors for observable than for elicitable signs (mean ± standard deviation [SD] κ, 0.70 ± 0.17 vs 0.41 ± 0.22, p = 0.002). Almost perfect agreement was seen for cerebellar signs and inspection (a combination of speed of movement, muscle bulk, wasting and tremor); substantial agreement for strength, gait and coordination; moderate agreement for tone and reflexes; and only fair agreement for sensation. The inter-rater agreement is therefore better for observable neurological signs than for elicitable signs, which may be explained by the additional skill and cooperation required to elicit rather than just observe clinical signs. These findings have implications for clinical practice, particularly in telemedicine, and highlight the need for standardisation of the neurological examination.

Abstract
INTRODUCTION Atypical febrile seizures (AFS) have been related with a higher incidence of severe pathologies of the central nervous system (CNS). Recent studies show a reduction in the prevalence of some of these diseases, a fact that could affect their management. AIMS. To determine the prevalence of severe pathologies of the CNS in patients treated for AFS in A and E departments and to detect any differences between these and patients suffering from AFS that is not associated to any severe pathology. PATIENTS AND METHODS A retrospective study was conducted by reviewing the medical records of patients diagnosed with AFS between November 2008 and November 2011. RESULTS Altogether, the sample consisted of 231 episodes of AFS (223 patients), with an average age of 1.7 years (p25-75=1.2-2.3 years), 133 (57.6%) of whom were males. Twelve patients (5.2%; 95% CI=2.7-8.9) were diagnosed with a severe pathology of the CNS. In patients with a severe pathology of the CNS, AFS is on most occasions the first episode (91.7% versus 63%; p=0.036) and more than one diagnostic criterion is present (50% versus 15.1%; p=0.007). Moreover, focal seizures (50% versus 12.8%; p=0.003) or epileptic status (25% versus 5.9%; p=0.041) are more common, and patients present altered levels of awareness that persist after the episode (66.7% versus 31.5%; p=0.002). CONCLUSIONS Given the fact that the prevalence of severe pathology of the CNS in patients with AFS is low, carrying out complementary tests or admission to hospital on a routine basis are not recommended. Certain characteristics of the episode increase the likelihood of AFS being the manifestation of a severe pathology of the CNS (being a first episode, presenting more than one diagnostic criterion for AFS and being a focal seizure or epileptic status), and should therefore be taken into account in the management of the patient.

Abstract
This study examined criterion-related validity and clinimetric properties of the pediatric balance scale (PBS) in children with cerebral palsy (CP). Forty-five children with CP (age range: 19-77 months) and their parents participated in this study. At baseline and at follow up, Pearson correlation coefficients were used to determine criterion-related validity by analyzing the correlation between the PBS, including PBS-static, PBS-dynamic, and PBS-total, and criterion measures, including the Gross Motor Function Measure-66 items (GMFM-66) and Functional Independence Measures for Children (WeeFIM). Responsiveness was examined by paired t test and by standardized response mean (SRM). The minimal detectable change (MDC) was analyzed at the 90% confidence level, and the minimal clinically important differences (MCID) was estimated by anchor-based and distribution-based approaches. The PBS with GMFM-66 and WeeFIM showed fair-to-excellent concurrent validity at pretreatment and follow up and predictive validity. The SRM values of all PBS scales were 0.75. For the PBS-static, PBS-dynamic, and PBS-total, the MDC(90) values were 0.79, 0.96, and 1.59, and the MCID ranges were 1.47-2.92, 2.23-2.92, and 3.66-5.83, respectively. Improvement of at least MDC values on the PBS can be considered a true change, not measurement error. A mean change must exceed the MCID range on PBS to be considered clinically important change. Therefore, all PBS scales were moderately responsive to change. Clinicians and researchers can use these clinimetric data for PBS to determine if a change score represents a true or clinically meaningful effect at posttreatment and follow up.

Abstract
BACKGROUND Supracondylar fracture of the humerus is one of the most common elbow injuries in children. It represents 60% elbow fractures and 16% all pediatric fractures. Extension-type fracture is the most frequent mechanism of this injury. MATERIAL/METHODS The aim of our study was to analyse early vascular and neurological complications of supracondylar humerus fractures in 122 children hospitalized in the Department of Orthopaedics and Traumatology, determine fracture types and duration of symptoms, as well as to establish methods of early diagnosis and treatment. The study covered cases of patients treated in the years 2004-2010. RESULTS Acute neurovascular complications occurred in 15% patients with supracondylar fractures (18 children). Nerve damage was found in 11% patients with displaced fractures (12 children). The average duration of symptoms was 49 days (ranging from 2 days to 5 months). Symptoms of vascular injury occurred in 8% children with displaced fractures (8 children) and were characterized by absent or weak pulse of the radial artery. CONCLUSIONS 1. Fracture reduction is a priority procedure in the cases of displaced supracondylar fracture, while further diagnostic steps and treatment of possible complications should only be applied afterwards. 2. The incidence of vascular and neurological complications positively correlates with fracture progression according to Gartland classification.

Abstract
BACKGROUND There have been no recent population-based studies on all-cause adult neurological morbidity in sub-Saharan Africa. We have developed a screening survey to improve the feasibility in performing these studies. METHODS Our screening instrument contains both history questions and examination items. We pilot tested this instrument in the Hai District, Tanzania, and Butajira, Ethiopia using trained individuals from the local communities. To measure sensitivity, we applied the instrument blindly to 25 previously-identified subjects with Parkinson's disease, stroke or epilepsy. To measure specificity, we examined 42 randomly selected previously screened subjects. We also compared the validity of the entire instrument to the history-only section. RESULTS There were 669 adult subjects screened in both communities (150 screen-positives, and 519 screen-negatives). The sensitivity of the instrument was 100% (95% CI 84.2-100%) and the specificity was 82.4% (95% CI 66.1-92.0%). However, when restricting the instrument to the history-only section, the sensitivity remained unchanged, but the specificity became 91.2% (95% CI 76.3-97.7%; p=0.48). CONCLUSIONS We have created a valid tool to screen adults for neurologic morbidity in resource-poor communities. The use of the history-only section of the tool is adequate as a screen and will improve feasibility.

Abstract
This study examined the arm position sense in children with Spastic Hemiparetic Cerebral Palsy (SHCP) and typically developing children (TD) by means of a contralateral matching task. This task required participants to match the position of one arm with the position of the other arm for different target distances and from different starting positions. Results showed that children with SHCP exhibited with both arms larger matching errors than the TD group, but only when the distance between the arms at the start of the movement was large. In addition, the difference in errors between the less-impaired and the impaired limb changed as a function of the distance in the SHCP group whereas no interlimb differences were found in the TD group. Finally, spasticity and restricted range of motion in children with SHCP were not related to the proportion of undershoot and size of absolute error. This suggests that SHCP could be associated with sensory problems in conjunction with their motor problems. In conclusion, the current study showed that accurate matching of the arms is greatly impaired in SHCP when compared to TD children, irrespective of which arm is used. Moreover, this deficit is particularly present for large movement amplitudes.

Abstract
This study examined criterion-related validity and clinimetric properties of the Pediatric Motor Activity Log (PMAL) in children with cerebral palsy. Study participants were 41 children (age range: 28-113 months) and their parents. Criterion-related validity was evaluated by the associations between the PMAL and criterion measures at baseline and posttreatment, including the self-care, mobility, and cognition subscale, the total performance of the Functional Independence Measure in children (WeeFIM), and the grasping and visual-motor integration of the Peabody Developmental Motor Scales. Pearson correlation coefficients were calculated. Responsiveness was examined using the paired t test and the standardized response mean, the minimal detectable change was captured at the 90% confidence level, and the minimal clinically important change was estimated using anchor-based and distribution-based approaches. The PMAL-QOM showed fair concurrent validity at pretreatment and posttreatment and predictive validity, whereas the PMAL-AOU had fair concurrent validity at posttreatment only. The PMAL-AOU and PMAL-QOM were both markedly responsive to change after treatment. Improvement of at least 0.67 points on the PMAL-AOU and 0.66 points on the PMAL-QOM can be considered as a true change, not measurement error. A mean change has to exceed the range of 0.39-0.94 on the PMAL-AOU and the range of 0.38-0.74 on the PMAL-QOM to be regarded as clinically important change.

Abstract
OBJECTIVE Frontline health professionals need a "red flag" tool to aid their decision making about whether to make a referral for a full diagnostic assessment for an autism spectrum condition (ASC) in children and adults. The aim was to identify 10 items on the Autism Spectrum Quotient (AQ) (Adult, Adolescent, and Child versions) and on the Quantitative Checklist for Autism in Toddlers (Q-CHAT) with good test accuracy. METHOD A case sample of more than 1,000 individuals with ASC (449 adults, 162 adolescents, 432 children and 126 toddlers) and a control sample of 3,000 controls (838 adults, 475 adolescents, 940 children, and 754 toddlers) with no ASC diagnosis participated. Case participants were recruited from the Autism Research Centre's database of volunteers. The control samples were recruited through a variety of sources. Participants completed full-length versions of the measures. The 10 best items were selected on each instrument to produce short versions. RESULTS At a cut-point of 6 on the AQ-10 adult, sensitivity was 0.88, specificity was 0.91, and positive predictive value (PPV) was 0.85. At a cut-point of 6 on the AQ-10 adolescent, sensitivity was 0.93, specificity was 0.95, and PPV was 0.86. At a cut-point of 6 on the AQ-10 child, sensitivity was 0.95, specificity was 0.97, and PPV was 0.94. At a cut-point of 3 on the Q-CHAT-10, sensitivity was 0.91, specificity was 0.89, and PPV was 0.58. Internal consistency was >0.85 on all measures. CONCLUSIONS The short measures have potential to aid referral decision making for specialist assessment and should be further evaluated.

Abstract
The diagnostic value and reliability of selected neurological clinical tests was studied in control subjects with normal neuroimaging (n=42), and subjects with a focal brain lesion (n=38). The items were studied by two examiners blinded to group membership and using standardized protocols, and subsequently by a neurologist who was not blinded to diagnosis. The positive likelihood ratios ranged from 1.06 (pronator drift) to 22.11 (single leg stance with eyes open, while the negative likelihood ratios ranged from 0.47 (tandem gait) to 0.97 (pupil symmetry). Three items (single leg stance - eyes closed - firm surface; single leg stance - eyes open - foam surface; and tandem gait) successfully distinguished between the two groups (odds ratio p<0.05). The inter-rater reliability was generally poor, with only tandem gait showing excellent agreement (kappa [K]=0.92). Tandem gait was the only item to show noteworthy agreement (K=0.93) between the examiners and the neurologist. The tests varied considerably in their ability to detect radiologically demonstrated structural brain lesions, and several items were poorly reproducible, questioning their value as part of a routine neurological examination.

Abstract
BACKGROUND There is a lack of consistent evidence regarding associations of neurological soft signs (NSS) with illness-related variables in schizophrenia. This study examined NSS in first-episode psychotic patients with respect to their factor structure and associations with risk factors, pre-morbid characteristics, psychopathology and spontaneous extrapyramidal syndromes. METHOD First-episode, drug-naive patients with schizophrenia-spectrum disorders (n=177) were assessed for NSS using the Neurological Evaluation Scale, and its 26 constituting items were factor analysed. The identified neurological dimensions were then entered into hierarchical regression models as outcome dependent variables of a set of predictors including risk factors (familial loading for schizophrenia, obstetric complications), pre-morbid characteristics (neurodevelopmental delay, symptoms of attention deficit-hyperactivity disorder, pre-morbid functioning), psychopathological domains (reality distortion, disorganization, negative symptoms, mania, depression, catatonia) and spontaneous extrapyramidal syndromes (parkinsonism, dyskinesia, akathisia). RESULTS Five neurological domains were identified: sequencing, release signs, sensory integration, abnormal movements and coordination. Multivariate analyses showed independent associations (p<0.01) of sequencing with familial liability to schizophrenia, deterioration of pre-morbid adjustment and parkinsonism; release signs with obstetric complications, catatonic symptoms and parkinsonism; sensory integration with familial liability to schizophrenia; abnormal movements with familial liability to schizophrenia, obstetric complications, parkinsonism and dyskinesia; and coordination with neurodevelopmental delay. The empirically derived factors explained additional variance over and above that explained by subscale scores across the examined variables. CONCLUSIONS Familial liability to schizophrenia, obstetric complications, neurodevelopmental delay, deterioration in pre-morbid functioning and observable motor disorders appear to contribute independently to domains of neurological dysfunction. The findings support a neurodevelopmental model of NSS in schizophrenia.

Abstract
The objective of this project was to develop sobriety tests that can be administered in the seated position to assist water patrol officers in detecting alcohol-related impairment in boaters. Four seated sobriety tests were administered to 330 boaters to determine the tests' usefulness in classifying boaters as having blood alcohol concentrations (BACs) below the illegal limit (BAC<.08%) or above the illegal limit (BAC ≥ .08%). Data were obtained by a team of four marine officers and two civilian observers on Lake of the Ozarks in central Missouri. The overall correct percentages, sensitivity, and specificity of the tests were consistent with what is typically reported in literature on the roadside sobriety tests. The tests' reliability was also consistent with what is typically reported in literature on the roadside sobriety tests. Thus, the four tests may assist marine officers with assessments of alcohol-related impairment in boaters.

Abstract
Caregivers of persons with profound intellectual and multiple disabilities (PIMD) often describe the quality of the daily movements of these persons in terms of flexibility or stiffness. Objective outcome measures for flexibility and stiffness are muscle tone or level of spasticity. Two instruments used to grade muscle tone and spasticity are the Modified Ashworth Scale (MAS) and the Modified Tardieu Scale (MTS). To date, however, no research has been performed to determine the psychometric properties of the MAS and MTS in persons with PIMD. Therefore, the purpose of this study was to determine the feasibility, test-retest reliability, and interrater reliability of the MAS and MTS in persons with PIMD. We assessed 35 participants on the MAS and MTS twice, first for the test and second a week later for the retest. Two observers performed the measurements. Feasibility was assessed based on the percentage of successful measurements. Test-retest and interrater reliability were determined by using the Wilcoxon signed rank test, intraclass correlation coefficients (ICC), Spearman's correlation, and either limits of agreement (LOA) or quadratically weighted kappa. The feasibility of the measurements was good, because an acceptable percentage of successful measurements were performed. MAS measurements had substantial to almost perfect quadratically weighted kappa (>0.8) and an acceptable ICC (>0.8) for both inter- and intrarater reliability. However, MTS measurements had insufficient ICCs, Spearman's correlations, and LOAs for both inter- and interrater reliability. Our data indicated that the feasibility of the MAS and MTS for measuring muscle tone in persons with PIMD was good. The MAS had sufficient test-retest and interrater reliability; however, the MTS had an insufficient test-retest and interrater reliability in persons with PIMD. Thus, the MAS may be a good method for evaluating the quality of daily movements in persons with PIMD. Providing test administrators with training and clear instructions will improve test reliability.

Abstract
BACKGROUND There is currently much interest in the use of decompressive craniectomy for patients with severe head injury. A number of studies have demonstrated that not only can the technique lower intracranial pressure but can also improve outcome. Whilst many patients who would otherwise have died or had a poor outcome now go on to make a good recovery, there is little doubt that complications can have a very significant impact on long term outcome. METHODS By using the corticosteroid randomisation after significant head injury (CRASH) collaborators outcome prediction model, three patients were selected who had a similar outcome prediction. All three patients developed intracranial hypertension following trauma and had a decompressive craniectomy. RESULTS Despite having a similar outcome prediction only one patient made an uneventful recovery. The remaining two patients suffered significant complications. CONCLUSIONS This report illustrates the potential clinical applications and limitations of an outcome prediction model and demonstrates the impact that complications can have on eventual outcome.

Abstract
OBJECTIVES Physical examinations performed by residents in many specialties are often incomplete and inaccurate. This report assessed the documentation of the neurologic examination performed by emergency medicine (EM) residents when examining patients with potential psychiatric or neurologic chief complaints. METHODS A retrospective chart review of neurologic examinations documented by EM residents was performed. An eight-item neurologic examination score was created and analyzed by resident postgraduate year. A linear mixed model was used to determine if differences in neurologic examination scores existed between resident year, type of complaint, and resident year and type of complaint. A one-point difference in scores was considered clinically important. RESULTS A total of 384 charts were reviewed. An average of 4.26 items (95% confidence interval [CI] = 3.91 to 4.62) out of a possible eight were documented that did not vary by resident year of training (p = 0.08). An effect was found for type of complaint. Documentation was lower for psychiatric than for neurologic complaints: mean score for psychiatric complaints 3.97 vs. mean score for neurologic complaints 4.55 (difference -0.58, 95% CI = -1.02 to -0.14). No interaction was found for type of complaint and resident year. A clustering effect was identified for individual residents. CONCLUSIONS Emergency medicine residents do not document detailed neurologic examinations on patients with neurologic or psychiatric complaints. Individual resident variation contributes to this documentation.

Abstract
BACKGROUND The objective of the study was to investigate neurological deficit in schizophrenia and to compare soft neurological signs in positive and negative subtypes of schizophrenia. SUBJECTS AND METHODS 66 patients with schizophrenia were evaluated with the Positive and Negative Syndrome Scale to classify the subtype of schizophrenia: positive subtype (36 patients) and negative subtype (30 patients), all of which were entering into remission. To examine the neurological soft signs we compared scores on the Neurological Evaluation Scale (NES) for positive and negative subtype. RESULTS The negative subtype of schizophrenia showed significantly higher neurological soft signs in comparison to the positive subtype, with reduced functioning in the sensory integration and motor coordination subscale as well as the other subscale. CONCLUSION The main finding in this study indicates that patients with schizophrenia have neurological impairment, and that the negative subtype has significantly higher neurological impairment than the positive subtype. The results further support the significance of the soft neurological signs as a possible marker of different subtypes of schizophrenia.

Abstract
BACKGROUND The aim of this study was to identify the characteristics of patients with stroke who were discharged home despite their need for acute hospital treatment. METHODS This study included 611 consecutive patients with ischemic stroke who were admitted to our hospital within 7 days of stroke onset. The patients were divided into two groups: those directly admitted and those readmitted after having previously been seen at our hospital or other facilities. The patients' characteristics and symptoms at the time of their initial visit were analyzed. RESULTS In all, 61 patients (10.0%) were initially discharged. The presence of hypertension, a summer admission, ambulance transport, and evaluation by neurologists were more frequent in the direct admission group than in the nondirect admission group. There was a lower incidence of consciousness disturbance and motor deficits in the nondirect admission group than in the direct admission group. The incidence of visual disturbance, gait disturbance, vertigo or dizziness, nausea, and sensory disturbance was higher in the nondirect admission group than in the direct admission group. On logistic regression model analysis, evaluation by nonneurologists (odds 33.0), hypertension (3.14), absence of consciousness disturbance (5.26), absence of paralysis (2.27), and presence of sensory disturbance (3.45) were independently associated with being initially discharged. CONCLUSION Physicians tend to consider that a patient has no need to be admitted into hospital if the patient is alert, has a sensory disturbance, or has no paralysis.

Abstract
OBJECTS Technical aspects of local chemotherapy in inoperable brainstem gliomas by convection-enhanced delivery (CED) are still under experimental considerations. In this study, we characterize the feasibility of multiple cannula placements in the rat brainstem. MATERIALS AND METHODS In 38 male Fisher rats, up to three guided screws were positioned in burr holes paramedian at 2.5 mm anterior and posterior to as well as at the lambdoid suture. Using Alzettrade mark pumps (1 microl/h flow rate over 7 days) either vehicle (5% dextrose) or 0.1 mg carboplatin was delivered via one, two, or three cannulas, respectively. During cannula insertion, electrocardiogram and respiratory rate was monitored. All rats were subsequently evaluated neurologically for 8 days. For drug distribution in coronal sections, the brain tissue concentration of platinum was measured. HE staining was used to evaluate the local site of drug delivery. Heart and respiratory rate remained within normal range during surgical procedure. Neurological scoring showed only mild neurological impairment in the groups receiving two or three cannulas, which resolved after vehicle delivery. However, after carboplatin delivery, this deficit remained unchanged. Drug distribution was more homogeneous in the three cannula group. Histological slices visualized edematous changes at the sight of cannula placement. CONCLUSION The unilateral application of up to three cannulas in the brainstem of rats for local drug delivery studies is feasible. The remaining neurological deficit in carboplatin-treated animals underlines the need of low toxicity drugs for CED in the brainstem.

Abstract
BACKGROUND Medication side-effects such as tardive dyskinesia (TD) are known to occur in individuals with a history of psychotropic drug use. This study aimed to contribute to the development of measures for assessing TD by examining the validity of the Matson Evaluation of Drug Side-effects (MEDS) with the Dyskinesia Identification System: Condensed User Scale (DISCUS) in 163 adults with intellectual disability (ID). METHOD To establish convergent validity, the relationship between the MEDS and the DISCUS in identifying TD was examined. To establish divergent validity, the ability of the MEDS to differentiate between TD and other side-effects was investigated. RESULTS The MEDS demonstrated convergent validity with the DISCUS on the Central Nervous System--Parkinsonism/Dyskinesia (CNS-PD) Subscale. The MEDS showed divergent validity with the DISCUS in cardiovascular and gastrointestinal side-effects, Parkinsonism symptoms (i.e., tremor, mask-like face), dystonia, and akathisia. DISCUSSION The MEDS appears to have significant clinical utility in measuring tardive dyskinesia and other medication side-effects in individuals with ID.

Abstract
BACKGROUND The purpose of the study was to describe sensorimotor profile in children with mild intellectual disability (ID), and to examine the association between cognitive and motor function. METHODS A total of 233 children with mild ID aged 7 to 8 years were evaluated with measures of cognitive, motor and sensory integrative functioning. RESULTS Children with mild ID performed significantly less well on all test measures. 44.2% of children scored in the impaired range on seven out of 22 sensorimotor measures. They had weaker fine motor skills than gross motor skills. Sensory integrative functions were only mildly impaired. Total IQ substantially predicted overall performance on each motor test. Specifically, verbal comprehension and processing speed indexes were significant predictors of gross and fine motor function. CONCLUSIONS Sensorimotor dysfunctions were found to be very frequent in children with mild ID. Early identification of sensorimotor impairments is essential to prompt early intervention and facilitate better integration into regular school settings.

Abstract
BACKGROUND AND PURPOSE In patients with systemic lupus erythematosus (SLE), severe neurological syndromes indicating central, peripheral or autonomic nervous system involvement are frequently seen. Antiphospholipid syndrome (APS) increases the risk of nervous system involvement. The aim of the study was to assess neurological manifestations occurring in patients with SLE and to evaluate their association with APS. MATERIAL AND METHODS One hundred thirty-seven patients (123 women and 14 men) with SLE were studied. Fifty out of 137 patients (43 women and 7 men) were diagnosed with APS. All patients underwent full neurological examination and diagnostics. Neurological syndromes were classified according to the standardized American College of Rheumatology (ACR) nomenclature. RESULTS Neurological syndromes were found in 89 cases out of 137 admitted SLE patients (64.96%). Headache was present in 52 patients (37.96%), polyneuropathy in 17 (12.41%), cerebrovascular disease in 13 (9.49%), seizures in 10 (7.3%), cranial neuropathy in 5 (3.65%), demyelinating syndrome in 5 (3.65%), mononeuropathy in 3 (2.19%), movement disorder in 3 (2.19%), and aseptic meningitis in 2 patients (1.46%). Our study indicated that 78% of patients with APS showed nervous system involvement as compared with 57.47% of SLE patients without APS (p=0.01). CONCLUSIONS Neurological syndromes occurring most frequently in SLE patients include headache, polyneuropathy and cerebrovascular diseases. Antiphospholipid syndrome increases the risk of nervous system involvement. We found that APS was strongly associated with neurological manifestations and in particular with cerebrovascular diseases and seizures.

Abstract
Each year 330 of every 100,000 inhabitants in Germany suffer a mild traumatic brain injury. About 25% suffer persisting post-concussion syndrome (headache, dizziness). Although many studies have been carried out to make a prognosis of the long-term outcome of these patients, there are still no relevant tests for a valuable statement. The aim of our study was to identify parameters to predict post-traumatic complaints. Therefore we conducted a prospective study of 74 patients who were admitted with a mild traumatic brain injury in our hospital from March 2004 till October 2006. We were able to show a significant correlation between complaints and a pathological CT-scan and biochemical markers during the first two weeks. For long-term complaints only the SKT (Syndromkurztest) we used for a neuropsychological assesment was able to show a significant correlation.

Abstract
The purpose of this study was to assess neurological soft signs in children and adolescents with isolated cleft of the lip or palate (iCL/P) compared with healthy controls. Children with iCL/P were recruited through the university cleft clinic. Control subjects were recruited through advertisements. Of the 166 subjects who participated (age range 7 to 17 years, M = 12.5, SD = 3.2), 77 had iCL/P (48 male) and 89 were healthy controls (44 male). All participants took the Physical and Neurological Examination of Subtle Signs and selected tests of motor coordination. A multivariate analysis of variance assessed differences between subjects with and without iCL/P. Also, a Pearson correlation estimated the relationship between the neurological soft signs and age. Subjects with iCL/P scored significantly higher on all neurological soft signs variables. These higher scores were associated with younger age. Findings lend support to the hypothesis of aberrant brain development in children with iCL/P.

Abstract
Recent findings suggest that compromised patient effort occurs in nonlitigious settings, but the nature and base rate of suboptimal effort in these settings remains poorly understood. In the treatment-seeking, acquired brain injury, outpatient rehabilitation sample included in this investigation, 21.8% of the patients scored below recommended cutting scores for suboptimal effort on the Test of Memory Malingering (TOMM). Disability status was the only variable explored in this study to be associated with suboptimal effort. It should be noted, however, that the proportion of patients on disability was large in both the optimal and suboptimal effort groups, suggesting that failure on the TOMM may not be a specific predictor of disability status in this sample. Importantly, performance on the TOMM was unrelated to age, education, time from injury to evaluation, and injury severity. Depression and anxiety were also shown to be unrelated to TOMM performance in this rehabilitation sample. As expected, performance on neurocognitive testing was significantly lower in the suboptimal effort group. This study suggests that reduced effort occurs outside forensic settings, is related to neuropsychometric performance, and urges further research into effort across various settings.

Abstract
The Modified Ashworth Scale (MAS) is a clinical scale used to assess muscle spasticity. While the evidence indicates that the reliability of the MAS is better in the upper limb and in certain distal muscle groups, no investigation has compared the effect of limbs and muscle groups on the MAS reliability. This study aimed to evaluate the effect of limb and muscle group on the reliability of the MAS in patients with spastic hemiplegia. Thirty subjects with upper and lower limb muscle spasticity were recruited for this trial. Two female experienced physiotherapists participated in this examination of reliability, and rated each patient in a randomized order in a single session. For the intrarater reliability, the second rater repeated the test 1 week later. Shoulder adductor, elbow flexor, wrist flexor, hip adductor, knee extensor, and ankle plantar flexor were tested on the hemiplegic side. Results demonstrated moderate inter (kappa=0.514, SE=0.046, p < 0.001) and intrarater (kappa=0.590, SE=0.051, p<0.001) reliability. For the inter and intrarater reliability, the agreement obtained for the upper and lower limb was similar. In the upper limb, the agreement between raters on the distal wrist flexor was significantly higher than the agreement on the proximal shoulder adductor. In the lower limb, there was a similar agreement between raters on the distal ankle plantar flexor and proximal hip adductor. For within rater, the agreement on the proximal and distal muscles of both limbs was not statistically significant. The Modified Ashworth Scale had moderate reliability. The limbs had no effect on the reliability. The agreement on distal wrist flexor in the upper limb was significantly higher between rater than in the proximal shoulder adductor. The agreement obtained with the MAS was not good, which questions the validity of the measurements.

Abstract
OBJECTIVE To establish the test-retest and interrater reliability as well as the concurrent construct validity of the Dynamic Gait Index (DGI) as a measure for dynamic balance in people with chronic stroke. DESIGN Cohort study. SETTING Day hospital and ambulatory care at a rehabilitation center. PARTICIPANTS A consecutive sample of 25 participants, at least 3 months poststroke and able to walk at least 10m with or without a walking aid, participated in the study. Two independent raters rated performances on the DGI. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The DGI was administered in 2 testing sessions 3 days apart. In the second session, the participants were rated by 2 raters. Intraclass correlation coefficients (ICCs), model 2,1, and the Bland and Altman method were used to analyze total scores and item scores. Concurrent construct validity was tested by correlating results to the Berg Balance Scale, the timed walking test, the Timed Up & Go test, and the Activities-specific Balance Confidence Scale. RESULTS ICCs for test-retest and interrater reliability of total scores were good (.96, .96, respectively) whereas reliability for single item scores was moderate to good (range, .55-.93). The hypotheses for concurrent construct validity were confirmed with all measures (range, .68-.83). CONCLUSIONS The DGI showed high reliability and showed evidence of concurrent validity with other balance and mobility scales. It is a useful clinical tool for evaluating dynamic balance in ambulatory people with chronic stroke.

Abstract
Non-motor symptoms (NMS) in Parkinson's disease (PD) are common, significantly reduce quality of life and at present there is no validated clinical tool to assess the progress or potential response to treatment of NMS. A new 30-item scale for the assessment of NMS in PD (NMSS) was developed. NMSS contains nine dimensions: cardiovascular, sleep/fatigue, mood/cognition, perceptual problems, attention/memory, gastrointestinal, urinary, sexual function, and miscellany. The metric attributes of this instrument were analyzed. Data from 242 patients mean age 67.2 +/- 11 years, duration of disease 6.4 +/- 6 years, and 57.3% male across all stages of PD were collected from the centers in Europe, USA, and Japan. The mean NMSS score was 56.5 +/- 40.7, (range: 0-243) and only one declared no NMS. The scale provided 99.2% complete data for the analysis with the total score being free of floor and ceiling effect. Satisfactory scaling assumptions (multitrait scaling success rate >95% for all domains except miscellany) and internal consistency were reported for most of the domains (mean alpha, 0.61). Factor analysis supported the a prori nine domain structure (63% of the variance) while a small test-retest study showed satisfactory reproducibility (ICC > 0.80) for all domains except cardiovascular (ICC = 0.45). In terms of validity, the scale showed modest association with indicators of motor symptom severity and disease progression but a high correlation with other measures of NMS (NMSQuest) and health-related quality of life measure (PDQ-8) (both, rS = 0.70). In conclusion, NMSS can be used to assess the frequency and severity of NMS in PD patients across all stages in conjunction with the recently validated non-motor questionnaire.

Abstract
Seizures have been reported frequently in feline infectious peritonitis (FIP) but have not been studied in detail in association with this disease. The purpose of this study was to perform a retrospective analysis of neurological signs in a population of 55 cats with a histopathologically confirmed neurological form of FIP. Seizure patterns were determined and it was attempted to relate occurrence of seizures with age, breed, sex and neuropathological features. Fourteen cats had seizure(s), while 41 cats had no history of seizure(s). Generalised tonic–clonic seizures were seen in nine cats; and complex focal seizures were observed in four patients. The exact type of seizure could not be determined in one cat. Status epilepticus was observed in one patient but seizure clusters were not encountered. Occurrence of seizures was not related to age, sex, breed or intensity of the inflammation in the central nervous system. However, seizures were significantly more frequent in animals with marked extension of the inflammatory lesions to the forebrain (P = 0.038). Thus, the occurrence of seizures in FIP indicates extensive brain damage and can, therefore, be considered to be an unfavourable prognostic sign.

Abstract
BACKGROUND The multicenter SPIDY trial (pallidal stimulation for generalized, idiopathic dystonia) recently reported a marked improvement in dystonia which was assessed by the Burke-Fahn-Marsden (BFM) scale. However, the reliability of this tool has rarely been evaluated and its use in a multicenter study has never been assessed prospectively. PURPOSE To evaluate the concordance between three unblinded clinical raters and one single-blinded rater for 10 prospective series of ratings on the BFM scale in 22 dystonic patients of the SPIDY study. METHODS Ten assessments on the BFM scale were performed under various stimulation conditions at different time points (before surgery and 1, 3, 6, and 12 months afterwards). Patients were first evaluated by three unblinded clinical raters (one per center). All assessments were videotaped and sent to a blinded rater. Intra- and inter-rater reliability was assessed using intraclass correlation coefficients. RESULTS The intra-rater reliability at inclusion was better for the blinded rater than for the clinical raters. The inter-rater reliability (comparing the blinded rater with each clinical rater) was "very good" at inclusion, "fair" at month 1 and was "good" at month 3, month 6, and month 12. CONCLUSION Blinding (rather than video) is probably the key factor in better intra-rater reliability and can produce more accurate rating than clinical rating. Consequently, a blind procedure should be performed systematically in multicenter studies. As inter-rater reliability is good in trained unblinded raters, the BFM scale may also be used in the follow up of dystonic patients in movement disorders centers, in clinical practice.

Abstract
OBJECTIVES Most of existing stroke scoring systems have limited ability to evaluate patients with cerebrovascular events in the vertebrobasilar territory. We devised a new scale, the Israeli Vertebrobasilar Stroke Scale (IVBSS) in order to directly and more accurately assess clinical deficits of patients with vertebrobasilar stroke. The present study measured the reliability and validity of the IVBSS. PATIENTS AND METHODS Forty-three patients (mean age+/-S.D., 70.9+/-8.8 years, 27 males) with vertebrobasilar stroke were evaluated with the IVBSS (11 items), the NIH Stroke Scale (NIHSS) and the disability modified Rankin Scale (mRS) by independent examiners. Interobserver agreement was rated by weighted kappa statistics for each item and the total IVBSS score. Validity was examined with Spearman rank coefficients to compare the IVBSS with NIHSS and mRS. RESULTS Excellent reliability was demonstrated between the examiners for almost each item and the total score of the IVBSS (kappa>0.75). The total IVBSS score was strongly associated with NIHSS and mRS results (r=0.80 and 0.76, respectively; P<0.0002). CONCLUSIONS The IVBSS is a valid instrument that allows the assessment of patients with vertebrobasilar stroke with high reliability. Further observations are warranted to determine the predictive value of the IVBSS for stroke outcome.

Abstract
The Assisting Hand Assessment (AHA) provides a new perspective of hand function evaluation relevant for children with unilateral upper limb disabilities. It measures how effectively the involved hand is actually used for bimanual activity, which, for these children, might be the most important aspect of their hand function. The aim of this paper is to report the conceptual framework and the evidence for validity, reliability, and responsiveness to change for the measures. Previously, the AHA has been evaluated for children aged 18 months to 5 years and excellent inter- and intrarater reliability was demonstrated. This paper reports further evidence of construct validity and reliability for the AHA measures involving an extended age range of children with hemiplegic cerebral palsy or obstetric brachial plexus palsy from 18 months to 12 years of age (mean age 4y 11mo [SD 2y 9mo] range 18mo-12y 8mo). A Rasch measurement model was used to analyze 409 assessments from 303 children (170 males, 133 females). The analysis generated a scale demonstrating large capacity to reliably separate and spread personal ability measures, indicating sensitivity to change and a hierarchy of the items ranging them from easy to hard. Aspects of item fit, relationship between age and ability measures, and development of assisting hand function are discussed.

Abstract
OBJECTIVE Paratonia is an external stimulus dependent increase in muscle tone that is absent at rest. It is thought to occur commonly in Alzheimer disease (AD) but is understudied. This study examines paratonia in a multiracial sample. METHODS The sample consisted of 80 patients who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for AD. They received a battery of neuropsychiatric assessments. The authors examined the relationship between paratonia and multiple variables. RESULTS Bivariate and logistic regression analyses revealed that paratonia correlated significantly with disease stage (based on the Geriatric Depression Scale) and number of frontal release symptoms. There were no significant correlations of paratonia with age, race, sex, depression, physical health, neuroimaging findings, functioning, or neuropsychiatric symptoms. The authors found significant association with frontal symptoms. CONCLUSIONS The potential utility of paratonia as an independent marker of disease stage in AD and its role in signifying frontal lobe dysfunction suggests that closer attention should be paid to its assessment.
