Facial expressions and identities recognition in Parkinson disease.

Parkinson's Disease (PD) is associated with motor and non-motor symptoms. Among the latter are deficits in matching, identification, and recognition of emotional facial expressions. On one hand, this deficit has been attributed to a dysfunction in emotion processing. Another explanation (which does not exclude the former) links this deficit with reduced facial expressiveness in these patients, which prevents them from properly understanding or embodying emotions. To disentangle the specific contribution of emotion comprehension and that of facial expression processing in PD's observed deficit with emotions we performed two experiments on non-emotional facial expressions. In Experiment 1, a group of PD patients and a group of Healthy Controls (HC) underwent a task of non-emotional expression recognition in faces of different identity and a task of identity recognition in faces with different expression. No differences were observed between the two groups in accuracies. In Experiment 2, PD patients and Healthy Controls underwent a task where they had to recognize the identity of faces encoded through a non-emotional facial expression, through a rigid head movement, or as neutral. Again, no group differences were observed. In none of the two experiments hypomimia scores had a specific effect on expression processing. We conclude that in PD patients the observed impairment with emotional expressions is likely due to a specific deficit for emotions to a greater extent than for facial expressivity processing.

Evidence-based improvement of gait in post-stroke patients following robot-assisted training: A systematic review.

BACKGROUND: The recovery of walking after stroke is a priority goal for recovering autonomy. In the last years robotic systems employed for Robotic Assisted Gait Training (RAGT) were developed. However, literature and clinical practice did not offer standardized RAGT protocol or pattern of evaluation scales. OBJECTIVE: This systematic review aimed to summarize the available evidence on the use of RAGT in post-stroke, following the CICERONE Consensus indications. METHODS: The literature search was conducted on PubMed, Cochrane Library and PEDro, including studies with the following criteria: 1) adult post-stroke survivors with gait disability in acute/subacute/chronic phase; 2) RAGT as intervention; 3) any comparators; 4) outcome regarding impairment, activity, and participation; 5) both primary studies and reviews. RESULTS: Sixty-one articles were selected. Data about characteristics of patients, level of disability, robotic devices used, RAGT protocols, outcome measures, and level of evidence were extracted. CONCLUSION: It is possible to identify robotic devices that are more suitable for specific phase disease and level of disability, but we identified significant variability in dose and protocols. RAGT as an add-on treatment seemed to be prevalent. Further studies are needed to investigate the outcomes achieved as a function of RAGT doses delivered.

Sensory Profile of Children and Adolescents with Autism Spectrum Disorder and Tip-Toe Behavior: Results of an Observational Pilot Study.

Atypical sensory processing is frequently reported in persons with autism spectrum disorders (ASD), and it is one of the described diagnostic criteria for ASD. There is also mounting literature supporting the presence of motor impairments in individuals with ASD. Among these motor signs, tip-toe behavior (TTB) is a possible clinical finding, but its etiology is not clearly understood. It is suggested that TTB in ASD could be a sign of a sensory modulation impairment, but evidence is lacking and controversial. The main aim of this pilot study is to explore sensory features in a sample (4 females; 28 males) of children and adolescents with ASD (age range: 7-18). All participants also presented Intellectual Disability. Participants were divided in two groups, matched for age and gender, on the basis of the presence or absence of TTB (16 ASD TTB group vs. 16 ASD NO-TTB group) and then evaluated by using the Short Sensory Profile. We found that both ASD groups tend to significantly present sensory-related behavioral symptoms, but ASD TTB individuals more frequently showed the specific pattern of "under responsive/seeks sensation" than ASD NO-TTB individuals. These preliminary findings support that sensory-motor features might be taken into consideration when rehabilitation for TTB in children and adolescents with ASD is necessary.

Combined Motor and Cognitive Rehabilitation: The Impact on Motor Performance in Patients with Mild Cognitive Impairment. Systematic Review and Meta-Analysis.

Mild cognitive impairment (MCI), a neurodegenerative disease leading to Alzheimer's disease or dementia, is often associated with physical complaints. Combined physical and cognitive training (PCT) has been investigated to see the effects on cognitive function, but its impact on motor functions and activities of daily living has not been explored yet. The combination of physical and cognitive training may be a valuable non-pharmacological intervention that could preserve motor function and quality of life (QoL). We aimed, therefore, to analyze if combined PCT is effective at improving motor performance in patients with an MCI. A systematic electronic literature search and a meta-analysis were conducted. The following criteria were compulsory for inclusion in the study: (1) randomized controlled trial design; (2) combined PCT compared to motor training alone or no intervention; (3) motor outcomes as a study's end point. Nine articles met the inclusion criteria. Results showed that PCT significantly enhances balance compared to motor training alone (SMD 0.56; 95% CI 0.07 to 1.06; I2 = 59%; 160 participants), whereas a significant improvement was found for mobility in the PCT group when compared to no intervention (MD -1.80; 95% CI -2.70 to -0.90; I2 = 0%; 81 participants). However, there is no evidence that people with MCI experience an increase in gait speed and QoL at the end of their practice sessions. Further investigation with larger samples and a longer period of monitoring after intervention should be undertaken.

Feasibility of a standardized protocol for respiratory training with intermitted positive pressure breathing ventilator application in dysphonia and dysarthria.

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.

Psychodynamic interpretation of linguistic findings in patients with epileptic and psychogenic non-epileptic seizures: the role of metaphors.

This work points out the main differences in the semantic expressions used by patients with psychogenic non-epileptic seizures (PNES) and epileptic seizures (ES). In reference to the body as a phenomenological entity, in ES the concept of the body-object prevails while in PNES the body, with all its life attributes, predominates. In description of seizures and in similitudes and metaphors used, ES patients focus on the description of the attack, trying to close the "gap" with a big effort, while patients with PNES concentrate on the context and on the presence of bystanders. Patients with PNES are unable to describe their own attack, since this it is not at the core of their distress, but rather the manifestation of something else, which is hiding the extreme anguish associated with experiences of the past that cannot be revealed (expressed). In the case of ES, instead, the ability to talk and the willingness to elaborate on the emotions become useful tools for facing the disease, an entity perhaps unsurmountable but at least manageable, to the benefit of everyone. In general, we can say that the experience of a disease (real or symbolic) deserves constant attention because it gives us the opportunity not only to probe the depth of the emotional experiences but also the psychic structure of the individual in front of us. A cure would not be a cure without considering such fundamental elements. It would become a sterile exercise of prescribing medications without paying attention to the person, which is the best way of preserving dignity in a state of illness.

Prosthesis rejection in individuals with limb amputation: a narrative review with respect to rehabilitation.

OBJECTIVE: To evaluate the refusal of the prosthesis in order to highlight elements in determining the acceptance/rejection of the prosthetic devices, and its role on rehabilitation program. METHODS: A literature review through a search of the database Medline for studies published between October 2007 and May 2020 using the key words "prosthesis", "limb", and "accept"*. RESULTS: Nine studies were included. Women appear to be more concerned about discomfort in using body-powered devices and about prosthesis cosmetic appearance. Level of limb amputation was considered relevant for prosthesis rejection only for the upper limb. Children fitted with prosthesis before two years old were less likely to abandon the prosthesis, preschool children have a lower drop-out prevalence compared to adults and school-age children. CONCLUSIONS: Understating the factors for rejections is crucial for more favorable health outcomes; multiple psychological factors should be considered during the rehabilitation process of individuals with limb amputation. Rehabilitation should consider psychosocial assistance for acceptance and perception of body representation and its discrepancy with the real body.

Evidence for managing chronic low back pain in primary care: a review of recommendations from high-quality clinical practice guidelines.

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.

Physiological Profile Assessment of Posture in Children and Adolescents with Autism Spectrum Disorder and Typically Developing Peers.

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.

Differences in Rehabilitation Needs after Stroke: A Similarity Analysis on the ICF Core Set for Stroke.

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.

Non-invasive current stimulation in vision recovery: a review of the literature.

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.

Linguistic analysis in the differential diagnosis between cognitive impairment and functional cognitive impairment (depression): a pilot study.

The differential diagnosis between cognitive impairment and functional cognitive impairment (depression) is complex and difficult, especially in the early stages of the disease. The aim of our study was to test linguistic analysis as a diagnostic tool to support clinical, and test-based diagnoses for this differential diagnosis. We enrolled 13 patients, requesting a diagnostic consultation in a Alzheimer Evaluation Unit. A provisional diagnosis through a neuropsychological evaluation (interview and neuropsychological tests) was made at baseline, while a definitive diagnosis was provided after six months, or, if not possible, after 12 months. The linguistic analysis was performed at T0 in blind by a linguist. Patients' language was studied at linguistic (morphological, syntactical, lexical literal and textual) and conversational (verbiage and humor) level. The correspondence rate between the linguistic analysis at T0 and the definitive diagnosis was 76.9%, compared to 58.4% between the neuropsychological équipe analyses at T0 and definitive diagnosis. There is no single patognomonic phenomenon for cognitive impairment or depression, but rather a linguistic cluster can lead to a diagnosis with a fairly good reliability.

Parameters Influencing Tracheostomy Decannulation in Patients Undergoing Rehabilitation after severe Acquired Brain Injury (sABI).

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.

Transcranial direct current stimulation (tDCS) combined with blindsight rehabilitation for the treatment of homonymous hemianopia: a report of two-cases.

[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.

Ultrasonography of the shoulder: asymptomatic findings from working-age women in the general population.

[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.

Physical Therapy Versus a General Exercise Programme in Patients with Hoehn Yahr Stage II Parkinson's Disease: A Randomized Controlled Trial.

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.
