ABSTRACT

BACKGROUND: Brain damage can affect several functions related to speech production leading to dysphonia and dysarthria. Most rehabilitation treatments focus on articulation training rather than on pneumophonic coordination and respiratory muscle strength. Respiratory training using an intermitted positive pressure breathing (IPPB) ventilator can be used for this last purpose; no agreement on a standard protocol has been reached to date. AIM: To evaluate the feasibility and the effectiveness of a standardized incremental protocol of respiratory training using IPPB to treat dysphonia and dysarthria. DESIGN: Case series study. SETTING: Neuropsychological Rehabilitation Unit in an Italian Neurorehabilitation Division. POPULATION: Thirty-two subjects with dysphonia and dysarthria resulting from neurological lesion. METHODS: Participants were assessed using clinical evaluation scales (GIRBAS scale of dysphonia, Robertson dysarthria profile), respiratory function test, and arterial blood gas analysis in air. The evaluations were performed at baseline and after 20 sessions of respiratory training with IPPB. The protocol provided a default increment of ventilator parameters. All subjects also underwent a standard speech and language therapy treatment. A satisfaction survey to assess acceptability and the Goal Attainment Scale were applied. RESULTS: All participants fulfilled the protocol. No complications or discomfort were reported. Subjects' satisfaction at survey was 97.7%. After respiratory training, all respiratory function parameters increased, but only maximal voluntary ventilation (MVV), maximum inspiratory pressure (MIP), and maximum expiratory pressure (MEP) were statistically significant (P<0.05). Clinical evaluation scales significantly improved (P<0.05). Correlation between respiratory function parameters and clinical evaluation scales showed a moderate correlation between MVV, MEP, MIP, and Robertson dysarthria profile (P<0.01). A weak correlation was found between MIP, MVV, and GIRBAS scale (P<0.05). CONCLUSIONS: Our protocol showed to be practical and well-tolerated. After respiratory training, MVV, MIP and MEP improved in significantly. Clinical scale scores improved in all participants. CLINICAL REHABILITATION IMPACT: Respiratory training using IPPB ventilator can be useful in implementing speech and language treatments in subjects with dysphonia and dysarthria linked to brain injury.

ABSTRACT

In older age, several observational studies investigated risk factors for suicide attempts/completed suicides; however, contrasting evidence came from population-based setting. In the present systematic review, we described through a narrative synthesis the significant associations existing among risk factors and suicide attempts/completed suicides in subjects aged >65 years. From the 39 population-based studies selected in six different databases until February 15, 2021, we analyzed the most frequent 28 risk factors for suicidal behaviour. The risk factors more associated to suicide attempts than other variables frequently related to suicidal behavior in older age were: depressive disorders, methods employed to self-harm (particularly poisoning), and psychotropic drug utilization followed by psychological factors and disability. Moreover, male sex, violent methods to self-harm, any psychiatric disorder (depression, anxiety and bipolar disorders), a poor medical condition, stressors/bereavement, and living alone appeared to be more significant for predicting completed suicides in late life. In older age, efforts for suicide prevention should be based on strategies to assess and treat psychiatric disorders along with psychological interventions, particularly in males.

ABSTRACT

BACKGROUND: Undocumented migrants experience many health problems; a comparison with a suitable control group of natives living in the same socio-economic conditions is still lacking. METHODS: Demographic data and data on risk factors, chronic conditions and dietary habits were obtained for 6933 adults (2950 Italians and 3983 undocumented migrants) receiving medical assistance from 40 non-governmental organizations all over the country. RESULTS: Attributed to the fact that these were unselected groups, differences were found in their demographic features, the main ones being their marital status (singles: 50.5% among Italians and 42.8% among migrants; P < 0.001). Smokers were more frequent among Italians (45.3% versus 42.7% P = 0.03); the same happened with hypertension (40.5% versus 34.5% P < 0.001). Migrants were more often overweight (44.1% versus 40.5% P < 0.001) and reporting a chronic condition (20.2% versus 14.4% P < 0.001). Among those on medications (n = 1354), Italians were fewer (n = 425) and on different medications. Differences emerged also in dietary habits. CONCLUSIONS: Differences in health conditions exist between native-borns and undocumented migrants, not because of a bias related to socio-economic conditions. Further studies are needed to design sustainable health policies and tailored prevention plans.

ABSTRACT

AIM: Chronic low back pain represents a major problem throughout the world which is increasing largely because of the aging world population. Clinical practice Guidelines can be powerful tools for promoting evidence-based practice, as they integrate research findings in order to support decision making. This study aimed to review recommendations for the management of Chronic low Back Pain in primary care based on high-quality recent and recently updated Clinical practice Guidelines. METHODS: CINHAL, PubMed, EMBASE, PEDro, Google Scholar, Government websites, Scientific Association websites were searched until April 2019. The retrieved documents underwent several consecutive selection steps: semi-automated duplicate screening, documents selection based on title and abstract screening. Finally, three independent investigators screened the documents for the selected inclusion criteria and reviewed the retrieved documents by means of the AGREE II instrument. RESULTS: A total of 3055 records were retrieved, of which 10 Clinical practice Guidelines met the inclusion criteria. The overall quality of these Clinical practice Guidelines was moderately variable. The recommendations of four Clinical practice Guidelines deemed as "excellent" were extracted and summarized. Although we tried to implement the most comprehensive research strategies, some Clinical practice Guidelines may be missing due to publication bias or incomplete indexing. CONCLUSIONS: This study showed a partial progress in respect of the methodological quality of the Clinical practice Guidelines. Several AGREE II domains demonstrated low scores, particularly the "applicability" and "monitoring and auditing criteria" are the domains most susceptible to amendments in future.Implications for rehabilitationClinicians should be aware that among recently published/updated clinical practice guidelines for the management of chronic low back pain in primary care only few were deemed to have high quality.Increasing evidence suggests the efficacy for self-management to improve low back pain outcome.Physical treatments are recommended in order to improve low back pain outcome while many physical modalities such as TENS, ultrasound, laser therapy are not.Psychological treatments are recommended and should be included as part of a broader treatment plan.

ABSTRACT

We asked a group of four researchers without experience in the field, to fill in the simplified Scoring Table based on Conversational Analysis principles. Researchers underwent a single-day training based on the linguistic differences in the event description by patients with epileptic seizures (ES) and psychogenic nonepileptic seizures (PNES). Two raters reached 100% agreement with the gold standard and even in the worst case the error was only 25%. This tool could be used for first screening, because it is very easy to administer, both for the interview and for the Scoring Table completion, confirming the usefulness of Conversation Analysis in differential diagnosis between ES and PNES.

ABSTRACT

A sound postural system requires sensorimotor integration. Evidence suggests that individuals with Autism Spectrum Disorder (ASD) present sensorimotor integration impairments. The Physiological Profile Assessment (PPA) can be used to evaluate postural capacity assessing five physiological subsets (i.e., vision, reaction time, peripheral sensation, lower limb strength, balance); however, no studies applied the PPA in young individuals. Therefore, this study aimed to investigate the PPA in children and adolescents with ASD compared with age-matched typically developing (TD) individuals and examine the relationship between the PPA subset within the ASD and TD participants according to different age groups. Percentiles from the PPA were obtained from the TD children and adolescents (n = 135) for each test. Performances of the individuals with ASD (n = 18) were examined relative to the TD percentiles. ASD participants' scores were above the 90th percentile (i.e., poor performance) in most sensory, motor and balance parameters. Performance in most of the PPA tests significantly improved with older age in the TD group but not in the ASD group. The study findings support the use of the PPA in TD children and adolescents while further research should investigate postural capacity in a larger ASD sample to enhance the understanding of sensorimotor systems contributing to compromised postural control.

ABSTRACT

Background: Successful rehabilitation is associated with physical, psychological, environmental, social, and personal factors based on the International Classification of Functioning, Disability and Health (ICF) framework. The influence of age has been suggested as crucial personal factors that may affect rehabilitation needs in post-stroke survivors. The aim of this study was to investigate the qualifiers of the ICF core set for stroke to detect differences in rehabilitation needs and goals between older (O, >65 years old) and younger (Y, ≤65 years old,) post-stroke individuals. Materials and methods: In this observational study, the comprehensive core set for stroke was filled during the rehabilitation period. Patient information was obtained using disability scales was translated into certain ICF categories using linking rules. Frequency, similarity, and linear regression analyses were performed for ICF qualifier profiles among Y and O patients. Results: Forty-eight ICF variables were significantly different between Y (n = 35, 46.17 ± 11.27 years old) and O (n = 35, 76.43 ± 6.77 years old) patients. Frequency analysis showed that activity of daily living and basic needs were more prevalent in O patients, whereas regaining of social role and social life were more prevalent in Y patients. The average Jaccard Index result (similarity analysis) was more homogeneous in O than in Y patients. Conclusions: ICF qualifiers are useful to design patient-centered care. Y patients have more heterogeneous needs and require more personalized program than O patients.

ABSTRACT

BACKGROUND: Around 253 million people worldwide suffer from irreversible visual damage. Numerous studies have been carried out in order to unveil the effects of electrical stimulation (ES) as a useful tool for rehabilitation for different visual conditions and pathologies. OBJECTIVE: This systematic review aimed to 1) examine the current evidence of ES efficacy for the treatment of visual pathologies and 2) define the corresponding degree of the recommendation of different ES techniques. METHODS: A systematic review was conducted in MEDLINE and Cochrane Library database to collect documents published between 2000 and 2018. For each study, Level of Evidence of Effectiveness of ES as well as the Class of Quality for the treatment of different visual pathologies were determined. RESULTS: Thirty-eight articles were included. Studies were grouped according to the pathology treated and the type of stimulation administered. The first group included studies treating pre-chiasmatic pathologies (age-related macular degeneration, macular dystrophy, retinal artery occlusion, retinitis pigmentosa, glaucoma, optic nerve damage, and optic neuropathy) using pre-chiasmatic stimulation; the second group included studies treating both pre-chiasmatic pathologies (amblyopia, myopia) and post-chiasmatic pathologies or brain conditions (hemianopsia, brain trauma) by means of post-chiasmatic stimulation. In the first group, repetitive transorbital alternating current stimulation (rtACS) reached level A recommendation, and transcorneal electrical stimulation (tcES) reached level B. In the second group, both high-frequency random noise stimulation (hf-RNS) and transcranial direct current stimulation (tDCS) reached level C recommendation. CONCLUSIONS: Study's findings suggest conclusive evidence for rtACS treatment. For other protocols results are promising but not conclusive since the examined studies assessed different stimulation parameters and endpoints. A comparison of the effects of different combinations of these variables still lacks in the literature. Further studies are needed to optimize existing protocols and determine if different protocols are needed for different diseases.

ABSTRACT

INTRODUCTION: Stroke may result in decreased trunk muscle strength and limited trunk coordination, frequently determining loss of autonomy due to the trunk impairment. Furthermore, sitting balance has been repeatedly identified as an important predictor of motor and functional recovery after stroke. Given the importance of the trunk, it is therefore mandatory that validated tools be available to assess its performance. A systematic review of the currently available clinical measurement tools to assess trunk performance after stroke has been carried out. EVIDENCE ACQUISITION: We searched the PubMed database from January 2006 to April 2017 to select articles which reported or included a clinical measure of trunk performance used in an adult stroke population. The data collected were integrated with the results of a previous review published in 2006. A total of 302 articles were identified, of which 19 were eligible for inclusion. EVIDENCE SYNTHESIS: Numerous clinical tools have been validated to assess trunk performance after stroke, including the Trunk Control Test, the Trunk Impairment Scale, the Postural Assessment Scale for Stroke, the Ottawa Sitting Scale, the Modified Functional Reach Test, the Function In Sitting Test, the Physical Ability Scale, the Trunk Recovery Scale, the Balance Assessment in Sitting and Standing Positions, and the and Sitting-Rising Test. CONCLUSIONS: Several scales and tests have been demonstrated to be valid for assessing trunk performance in stroke. Some of these have already been refined by Rasch analysis to increase their psychometric characteristics. Further psychometric analysis of these tools in large and different samples is, however, still needed.

ABSTRACT

Introduction Tracheostomy weaning in patients who suffered a severe acquired brain injury is often a challenge and decannulation failures are not uncommon. Objective Our study objective is to describe the decannulation failure rate in patients undergoing rehabilitation following a severe acquired brain injury (sABI); to describe the factors associated with a successful tube weaning. Methods We conduct a retrospective analysis of charts, consecutively retrieved considering a 3-year window. Variables analyzed were: age, sex, body mass index (BMI), Glasgow Coma Scale (GCS), cause of hospitalization (stroke, trauma, cardiac arrest), date of the pathological event, gap between the index event and the first day of hospitalization, duration of Neurorehabilitation Ward hospitalization, comorbidities, chest morphological alteration, kind of tracheostomy tube used (overall dimension, cap, fenestration), SpO2, presentation and quantification of pulmonary secretion, maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP), respiratory frequency and pattern, cardiac frequency, presence of spontaneous cough, cough strength, and blood gas analysis. Results We analyzed 45 tracheostomised sABI patients following stroke, trauma, or cardiac arrest. The weaning success percentage was higher in Head Trauma patients and in patients presenting positive spontaneous cough. Failures seem to be associated with presence of secretions and anoxic brain damage. GCS seemed not related to the decannulation outcome. Conclusions Parameters that could be used as positive predictors of weaning are: mean expiratory pressure, presence of spontaneous cough, and cough strength. Provoked cough and GCS were not predictive of weaning success.

ABSTRACT

[Purpose] Homonymous hemianopia is one of the most common symptoms following neurologic damage leading to impairments of functional abilities and activities of daily living. There are two main types of restorative rehabilitation in hemianopia: "border training" which involves exercising vision at the edge of the damaged visual field, and "blindsight training," which is based on exercising the unconscious perceptual functions deep inside the blind hemifield. Only border effects have been shown to be facilitated by transcranial direct current stimulation (tDCS). This pilot study represents the first attempt to associate the modulatory effects of tDCS over the parieto-occipital cortex to blindsight treatment in the rehabilitation of the homonymous hemianopia. [Subjects and Methods] Patients TA and MR both had chronic hemianopia. TA underwent blindsight treatment which was combined with tDCS followed by blindsight training alone. MR underwent the two training rounds in reverse order. [Results] The patients showed better scores in clinical-instrumental, functional, and ecological assessments after tDCS combined with blindsight rehabilitation rather than rehabilitation alone. [Conclusion] In this two-case report parietal-occipital tDCS modulate the effects induced by blindsight treatment on hemianopia.

ABSTRACT

[Purpose] The aim of this study was to estimate the prevalence of abnormal shoulder ultrasonographic findings in a sample of asymptomatic women. [Subjects and Methods] A secondary analysis of a cross-sectional study was performed. We recruited 305 women (aged 18-56 years). All the subjects had a structured interview screening for self-reported symptoms and underwent a shoulder ultrasonographic examination, in which both shoulders were examined. The radiologist was blinded to the clinical history of the participants. All detectable shoulder abnormalities were collected. [Results] Of the subjects, 228 (74.75%) were asymptomatic at both shoulders, and 456 asymptomatic shoulders were analyzed. Lack of uniformity (supraspinatus, infraspinatus, subscapularis, and biceps brachii long head) was found in 28 shoulders (6.14%), 19 (4.17%) on the dominant side and 9 (1.97%) on the non-dominant side. Tendinosis (supraspinatus, infraspinatus, subscapularis, and biceps brachii long head) was found in 19 shoulders (5.32%), 12 (2.63%) on the dominant side and 7 (1.53%) on the non-dominant side. Calcification and other abnormal findings were reported. [Conclusion] The most common abnormalities were calcifications within the rotator-cuff tendons and humeral head geodes; other degenerative findings were less common.

ABSTRACT

To evaluate psychotropic drug use in undocumented migrants and natives in the same conditions of poverty. We studied drug dispensation by a nongovernmental organization during the year 2014. Drugs were identified according to the Anatomical Chemical Therapeutic classification and their quantity was measured in defined daily doses (DDD). We determined the percentage of patients taking at least one medicine with psychotropic activity in relation to the total number of patients receiving medicines of any class. We also calculated the individual DDD for psychoactive drugs. The percentage of natives receiving this type of medicine is significantly higher than that of undocumented migrants. Individual DDDs for each class of psychotropic drug are comparable in Italians and undocumented migrants and, among the latter, no difference was found in relation to ethnicity. Our findings describe for the first time the use of psychotropic medicines by undocumented migrants. On this basis, we hypothesize that poverty is more important than migration and ethnicity in generating the need for this type of pharmacological treatment. Both natives and undocumented migrants show poor adherence to treatment. This situation should be considered when programming health interventions in this field for the very poor and undocumented migrants.

ABSTRACT

BACKGROUND AND OBJECTIVE: Several studies suggest that general exercise (GE) and physical therapy programmes (PT) improve the outcomes of Parkinson's disease (PD) patients; however, the available data do not allow a determination of which treatment is more effective. Our study aims to compare the effects of physiotherapy and general exercise in Parkinson's disease. METHODS: Design and setting: Randomized controlled trial -general hospital outpatient clinic. The participants were patients with Hoehn Yahr stage II PD. Two randomized groups: one receiving PT and one receiving GE. The outcome measures were the FIM, Hamilton Rating Scale, TUG test, and UPDRS. RESULTS: FIM median scores improved by 3 points in the PT group after treatment, and the improvements were maintained at follow-up. The GE FIM median scores were unchanged after treatment and were reduced by 1 point at follow-up (p < 0.05). The TUG test time was reduced in the PT group but increased in the GE group with a 3-second difference between groups at follow-up, suggesting improved functional mobility after specific physiotherapy (p < 0.05). The UPDRS median score change from baseline was significantly different between the two groups at the end of treatment (6.5 points) and at follow-up (11 points), with a benefit for the physiotherapy group. CONCLUSIONS: Physiotherapy seems to be more effective than a generic exercise programme in patients with Hoehn Yahr stage II PD.

ABSTRACT

We analysed drug dispensation by charitable organisations in a year time. Drugs were grouped according to the Anatomic Therapeutic Chemical classification and the amount dispensed was calculated with the system of the Daily Defined Dose (DDD) and expressed as DDD/1000 subjects/day. A number of 87,550 subjects were studied (13,308 Italians; 74,242 Immigrants). Though we noticed a great sesonal variability, the drugs most frequently dispensed were those for the respiratory, cardiovascular and gastrointestinal system and antibiotics, which is different from the rest of the Italian population and the immigrant population assisted by our National Health Service (NHS). We also found that chronic diseases are increasing in these subjects. We conclude that the subjects not receiving NHS assitance have, at least in part, different health patterns and requirements. This should be considered when planning tailored interventions.

ABSTRACT

About 20%-30% of patients undergoing neurological rehabilitation report visual field defects, one of the most frequent of which is homonymous hemianopsia (loss of the same half of the visual field in both eyes). There is still no consensus as to whether homonymous hemianopsia is best treated in a restorative or compensatory manner. The aim of this review is to describe the effects of restorative rehabilitation, whose long-term efficacy is still being debated. We analyzed 56 articles describing the use of various techniques used to promote visual field recovery but concentrating on two approaches: "border training," which involves exercising vision at the edge of the damaged visual field, and "blindsight training," which is based on exercising unconscious perceptual functions in the mild of the blind hemifield where the scotoma is deep. Both techniques have been supported by functional imaging studies showing evidence of cortical rearrangement (plasticity) after rehabilitation. Although no formal meta-analysis was possible, the results of a semiquantitative evaluation suggested that the improvement in visual skills obtained is related to the type of training used: Border rehabilitation seems to improve the detection of visual stimuli, whereas blindsight rehabilitation seems to improve their processing. Finally, the addition of transcranial direct current stimulation seems to enhance the effects of visual field rehabilitation.

ABSTRACT

BACKGROUND: The bilateral transfer of a motor skill is a physiological phenomenon: the development of a motor skill with one hand can trigger the development of the same ability of the other hand. OBJECTIVE: The purpose of this study was to verify whether bilateral transfer is associated with a specific brain activation pattern using functional magnetic resonance imaging (fMRI). METHODS: The motor task was implemented as the execution of the Nine Hole Peg Test. Fifteen healthy subjects (10 right-handers and five left-handers) underwent two identical fMRI runs performing the motor task with the non-dominant hand. Between the first and the second run, each subject was intensively trained for five minutes to perform the same motor task with the dominant hand. RESULTS: Comparing the two functional scans across the pool of subjects, a change of the motor activation pattern was observed. In particular, we observed, in the second run, a change in the activation pattern both in the cerebellum and in the cerebral cortex. We found activations in cortical areas involved in somatosensory integration, areas involved in procedural memory. CONCLUSIONS: Our study shows, in a small group of healthy subjects, the modification of the fMRI activation pathway of a motor task performed by the non-dominant hand after intensive exercise performing the same task with the dominant hand.
