Abstract
UNLABELLED Positional plagiocephaly (PP) denotes flattening of the skull that occurs frequently in healthy infants. Aim of this study was to estimate the prevalence of positional plagiocephaly and to identify the risk factors in a cohort of healthy infants in order to help prevention of PP. In a prospective design, all healthy full-term infants, ranging from 8 to 12 weeks of age, who presented at the public immunization clinic in Ferrara, were eligible for the study. After obtaining informed consent, we interviewed the parents and examined the infants using the Argenta's assessment tool. Of 283 infants examined, 107 (37.8%) were found to have PP at 8-12 weeks of age. In 64.5%, PP was on the right side, 50.5% were male and 15% presented also with brachycephaly. Risk factors significantly associated were lower head circumference, advanced maternal age, Italian compared to African, and supine sleep position, in particular for infants born at 37 weeks, preference for one side of the head. In logistic regression, risk factors significantly associated were lower birth weight, advanced maternal age, and supine sleep position. CONCLUSIONS Positional plagiocephaly is a common issue faced by pediatricians; our results reinforce the need of improving prevention both of sudden infant death and positional plagiocephaly, through uniform messages provided prenatally and postnatally by different health professionals. "What is Known:" •The incidence of positional plagiocephaly varies due to population studied and measuring methods. •Different factors are considered in the literature as being associated to positional plagiocephaly (infant factors, obstetric factors, infant care practices, sociodemographic factors). "What is New:" •This is one of the few European studies quantifying positional plagiocephaly prevalence in a population of unselected healthy infants. •In this study, positional plagiocephaly is confirmed as a common issue, related to some factor (as supine sleep position and positional head prevalence) that should be addressed in pre and postnatal counseling. •The prone sleepers rate in our population highlight the need to improve parental awareness regarding SIDS prevention, in particular in borderline gestational age.

Abstract
OBJECTIVES Feasibility, validity, and diagnostic accuracy of a non-invasive dynamic ambulatory test were assessed with near infrared spectroscopy (NIRS) evaluating foot perfusion in peripheral arterial disease (PAD). METHODS This was a prospective observational study. Eighty PAD patients (63 males, 71 ± 9 years), including 41 patients with coexisting diabetes, participated. Thirteen healthy subjects (8 males, 26 ± 8 years) were also studied by echo colour Doppler providing 160 diseased and 26 non-diseased limbs. Under identical clinostatic conditions, participants performed a 10-repetition toe flexion tests with NIRS probes on the dorsum of each foot; the area under the curve of the oxygenated haemoglobin trace ("toflex area") was calculated and the ankle-brachial index (ABI) was measured. Time of execution, rate of wrong tests, and adverse reactions were recorded. Within session reliability was assessed by administering the test twice, with a 5 minute interval between tests. The validity was assessed determining whether the toflex area was (a) dependent on the oxygen delivery from the lower limb arteries simulating PAD conditions by a progressive blood flow restriction (40-120% of systolic pressure) in healthy subjects; (b) consistent with the degree of PAD ranked by ABI and correlated with ABI and ankle pressure values in PAD patients. The diagnostic accuracy in detecting PAD was compared with examination using echo colour Doppler ultrasound. RESULTS All tests were rapidly, satisfactorily (<1% mistakes), and safely performed. Toflex area values, superimposable in the two sessions (intra-class correlation coefficient 0.92), were comparable to PAD values following blood flow restriction, consistent with PAD severity, correlated with dorsal pedis artery pressure (r = .21; p = .007) and ABI (r = .65; p < .001) in PAD, but not in the presence of diabetes. Toflex area was similar to echo colour Doppler for detecting PAD following receiver operating characteristic curve analysis (area = 0.987, p < .001; toflex area values ≤ -28 arbitrary units, sensitivity/specificity 95.6/100). CONCLUSION The toe flexion test enables ambulatory assessment of foot perfusion and PAD detection, even in the presence of non-measurable ABI or diseases affecting the microcirculation.

Abstract
BACKGROUND Gait disorders are common in multiple sclerosis (MS) and lead to a progressive reduction of function and quality of life. OBJECTIVE Test the effects of robot-assisted gait rehabilitation in MS subjects through a pilot randomized-controlled study. METHODS We enrolled MS subjects with Expanded Disability Status Scale scores within 4.5-6.5. The experimental group received 12 robot-assisted gait training sessions over 6 weeks. The control group received the same amount of conventional physiotherapy. Outcomes measures were both biomechanical assessment of gait, including kinematics and spatio-temporal parameters, and clinical test of walking endurance (six-minute walk test) and mobility (Up and Go Test). RESULTS 16 subjects (n = 8 experimental group, n = 8 control group) were included in the final analysis. At baseline the two groups were similar in all variables, except for step length. Data showed walking endurance, as well as spatio-temporal gait parameters improvements after robot-assisted gait training. Pelvic antiversion and reduced hip extension during terminal stance ameliorated after aforementioned intervention. CONCLUSIONS Robot-assisted gait training seems to be effective in increasing walking competency in MS subjects. Moreover, it could be helpful in restoring the kinematic of the hip and pelvis.

Abstract
AIM Chronic fatigue (CF) severely affects patients with multiple sclerosis (MS), but its pathogenesis remains elusive and the effectiveness of available treatments is modest. We aimed to evaluate the effect on CF of the balloon dilatation of stenosing lesions affecting the main extracranial veins configuring the chronic cerebrospinal venous insufficiency (CCSVI), a condition strongly associated with MS. METHODS Thirty-one MS consecutive patients (16 males, age 46.2+/-9.4 years) with associated CCSVI and CF underwent the endovascular procedure. Fatigue was assessed using the Fatigue Severity Scale (FSS) and Modified Fatigue Impact Scale (MFIS) at baseline (T0) and one (T1), six (T6) and twelve (T12) months after the procedure. In ambulatory patients (N.=28), mobility was evaluated using the 6-min walking test at T0 and T1. RESULTS and MFIS scores significantly improved from preoperative values, and the positive trend was maintained at one year (FSS: T0=5.1+/-1.0 to T12=3.5+/-1.8, P<0.001; MFIS-total score: T0=34.9+/-14.8 to T12=22.5+/-13.7, P<0.001; MFIS-Physical subscale: T0=21.2+/-8.0 to T12=13.5+/-9.7 P<0.001; MFIS-Cognitive subscale: T0=9.2+/-9.5 to T12=6.0+/-6.3, P=0.03; MFIS-Psychosocial subscale: T0=4.5+/-2.1 to T12=2.5+/-2.1, P<0.001). Six-min walking distance (6MWD) at T1 improved significantly (332+/-190m to 378+/-200m, P=0.0002). In addition, an inverted correlation between 6MWD and MFIS-physical subscale variations was found in the subgroup of patients (N.=8) with no lower limb motor impairment (r=-0.74, P=0.035). CONCLUSION The reestablishment of cerebral venous return dramatically reduced CF perception in a group of MS patients with associated CCSVI, suggesting that CF is likely the symptom of CCSVI.

Abstract
AIM The aim of this study was to propose a kinematic classification of gait according to six minute walk test performance. METHODS Thirty-four hemiplegic subjects were enrolled. Six-minute walk test (SMWT), gait analysis and Walking Handicap Scale score (WHS) were measured. A k-means cluster analysis was used to classify the sample into three sub-groups which were homogeneous in spatio-temporal parameters, kinematic variables, and which reflected three meaningful levels of walking competency. RESULTS Three clusters were identified: low-functioning walkers (Cluster 1) walked for 88-172 m; intermediate-functioning walkers (Cluster 2) walked for 180-302 m and high-functioning walkers (Cluster 3) were able to cover 349-430 m. The authors found homogeneous gait profiles in these subgroups. Between-group differences on kinematic data and WHS scores were also underlined. CONCLUSIONS Cluster analysis was able to identify consistent gait characteristics of spatio-temporal, walking endurance and sagittal plane kinematic profiles in hemiplegic subjects and is useful for categorizing the levels of walking competency in these subjects.

Abstract
Stroke is one of the main causes of death and disability in the adult population. Changes in pituitary hormone secretion may be observed during the acute phase of stroke, representing part of the adaptive response to injury. However, reduced pituitary hormone secretion, caused by pituitary and/or hypothalamus damage, may also occur. Hypopituitarism has been observed in 19% of patients with ischemic stroke and 47% of patients with subarachnoid hemorrhage, presenting as an isolated deficiency in most cases. Diabetes insipidus is very rare. Low IGF-I levels, during the acute phase of stroke, have been associated with poor outcome and high mortality. During rehabilitation, higher IGF-I levels have been observed in patients with better outcome, suggesting a neuroprotective role of IGF-I. Accurate evaluation and long-term follow-up of all patients with stroke are necessary to define the prevalence of hypopituitarism, and its relationship with type, severity, and outcome from stroke. Discovery and adequate treatment of possible endocrine deficiencies may improve outcome and quality of life of patients with stroke.

Abstract
AIM To verify the effectiveness of a 120 day home-based program guided by the pain threshold speed (PTS). METHODS Twenty-nine patients with stable claudication were measured for ankle pressure (AP), ankle-brachial index (ABI), PTS, maximal speed (Smax) on treadmill. Daily walking sessions at a speed 20-30% below PTS were prescribed. Determination of the training speed was supervised and facilitated at home. The program included a daily record of exercise data and symptoms, an intermediate PTS re-evaluation to adjust the training speed, and the reassessment of all the parameters after 120 days. RESULTS Overall patients showed a reduction of systemic blood pressure (151.3+/-14.3 to 147.6+/-18.3 mmHg; 77.1 +/-9.1 to 72.4+/-8, p=0.008) while AP did not. ABI increased from 0.65+/-0.13 to 0.71+/- 0.18 (p=0.01). PTS and Smax rose from 3.2+/-1.1 to 4.2+/-1.5 km/h (p=0.0001) and from 3.9+/-1.3 to 4.6+/-1.3 km/h (p=0.0001), respectively. According to their compliance, patients were divided into 3 groups: 1) trained (T, n=14): exercise at the prescribed speed, 2) free-walkers (FW, n=7): walking speed markedly below PTS and 3) untrained (U, n=8): incomplete program compliance. T group showed symptom reduction up to pain disappearance. The ABI change (0.72+/-0.09 to 0.82+/- 0.16, p<0.02) was correlated to AP increase (r= 0.879). PTS and Smax rose from 3.6+/-1.1 to 5.4+/-0.8 km/h (p<0.02) and from 4.7+/-1.2 to 5.7+/-0.7 (p<0.02), respectively. FW showed improvement of all parameters, and U a better walking efficiency. CONCLUSIONS In patients with claudication, a low-cost home-based program driven by PTS allows dramatic improvements of functional parameters.

Abstract
The importance of the duration of contraction on the excitability of the motoneuronal pool was evaluated by measuring the H reflex from soleus muscle after short and long contractions at constant effort equal to 60% maximal voluntary contraction (MVC); the difference between the amplitude of H reflex at rest and after contraction of different duration was evaluated in 10 normal subjects and in one hemiparetic patient. The authors found a significant inhibition of H reflex after contraction of 10 seconds and after 40 seconds and a longer duration of the inhibition after 40 seconds. In the hemiparetic patient the H reflex did not show inhibition which suggests a possible reduction of the presynaptic inhibition, and a lack of modulation of the motoneuronal pool after contraction.

Abstract
Twenty-four patients, showing a good clinical recovery from coma-inducing injury and coping well with the activities of everyday living, were tested, at least 1 year after trauma, on motor speed and reaction time, and given a neuropsychological examination. While the patients generally performed within the normal range on the neuropsychological tests, their motor speeds and reaction times--both simple (SRT) and complex (CRT)--were significantly slower than those of matched controls. This points to a subclinical bradykinesia. The patients' motor speed scores did not correlate significantly with any of the neuropsychological tests; nor did SRT or CRT. While the difference between simple and complex reaction time was significantly greater in the patient group, the percentage difference was not significantly different between the two groups. Collectively, these results suggest that bradykinesia and bradyphrenia do not necessarily overlap. Finally, there was no significant correlation between motor performance and severity of original injury, whether the latter was measured by number and size of lesions or by duration of post-traumatic amnesia.

Abstract
We examined 14 vegetative brain-injured patients with proton magnetic resonance single-volume spectroscopy (1H MRS) at 1.5 T to establish whether there were changes in relative concentrations of N-acetyl aspartate (NAA), choline (Cho) and creatine (CR) metabolites from those found in healthy brains. Spectra were obtained from two different (2 x 2 x 2 cm) volumes of interest in the left and in the right frontal cortex, normal on MRI. All spectra revealed abnormalities compared with normal spectra obtained from age-matched control subjects. Values outside the normal range for at least one of the metabolite ratios were observed in all patients. Cho/Cr was markedly higher and NAA/Cho and NAA/Cr were markedly lower than in the control subjects. At different times six patients regained awareness and the ability to obey commands, and four were re-examined; changes in metabolite ratios were observed, which were different in individual patients. The NAA/Cho ratio reaches statistical significance in discriminating between the patients with a poor outcome (death or prolonged vegetative state) and those who regained awareness; the dividing line appears to be at a value of about 1.6.

Abstract
A patient presented left-sided apraxia, constructional disturbances with the right hand and left tactile anomia after a severe head injury. MRI showed a callosal lesion involving the middle and posterior third of the truncus. This finding supports the thesis that the posterior callosum plays a predominant role in the interhemispheric mediation for praxis, as well as in the right-left transfer of spatial information guiding constructional performance. Left-sided apraxia was evident on imitation, on verbal command and on visual presentation of an object, but not on tactual presentation and during the actual use of objects. Moreover, apraxia on imitation showed a more rapid recovery than apraxia on verbal command. These data are consistent with the hypothesis of a left-hemisphere dominance for praxis, which is almost absolute when the retrieval of the appropriate gesture requires a semantic analysis of the stimulus.

Abstract
Muscular hypotrophy due to arm or leg immobilization (MH) in absence of neuromuscular pathologies was tested by EMG spectral analysis, in order to identify a possible neurophysiological method able to analyze this kind of particular clinical picture. Two different groups of patients were tested. In group 1 the patients were suffering from vastus medialis muscle MH due to meniscus surgery, in group 2 the patients were suffering from biceps brachii muscle MH after humerus fracture. A significant difference between normal and pathological muscles was found and the methods may be useful in the neurophysiological evaluation of MH.
