The role of brain oscillations in post-stroke motor recovery: An overview

Stroke is the second cause of disability and death worldwide, highly impacting patient’s quality of life. Several changes in brain architecture and function led by stroke can be disclosed by neurophysiological techniques. Specifically, electroencephalogram (EEG) can disclose brain oscillatory rhythms, which can be considered as a possible outcome measure for stroke recovery, and potentially shaped by neuromodulation techniques. We performed a review of randomized controlled trials on the role of brain oscillations in patients with post-stroke searching the following databases: Pubmed, Scopus, and the Web of Science, from 2012 to 2022. Thirteen studies involving 346 patients in total were included. Patients in the control groups received various treatments (sham or different stimulation modalities) in different post-stroke phases. This review describes the state of the art in the existing randomized controlled trials evaluating post-stroke motor function recovery after conventional rehabilitation treatment associated with neuromodulation techniques. Moreover, the role of brain pattern rhythms to modulate cortical excitability has been analyzed. To date, neuromodulation approaches could be considered a valid tool to improve stroke rehabilitation outcomes, despite more high-quality, and homogeneous randomized clinical trials are needed to determine to which extent motor functional impairment after stroke can be improved by neuromodulation approaches and which one could provide better functional outcomes. However, the high reproducibility of brain oscillatory rhythms could be considered a promising predictive outcome measure applicable to evaluate patients with stroke recovery after rehabilitation

Early hip fracture surgery and rehabilitation. How to improve functional quality outcomes. A retrospective study

Introduction: Hip fractures are one of the major disability causes associated with a high morbidity and mortality rate. Early surgery and stable fixation could be associated with better pain control, possibly lower mortality rates, and early recovery of autonomy. Aim: The aim of this study was to analyze a population affected by hip fractures exploring the effects of an early surgery and rehabilitation approach in relation to functional outcomes. Materials and methods: This study included 140 adult patients (mean age 79.35±11.71, range 66-94 years) with hip fractures admitted to the orthopedic unit of the University Hospital of Messina who underwent surgery and a rehabilitation program while hospitalized. Exclusion criteria were patients not surgically treated or discharged with no rehabilitation sessions. Clinical outcomes were evaluated post-surgery and before discharge as follows: pain quantification using the visual analogue scale and functional evaluation using the Barthel Index. A rehabilitation protocol was started within 48 hours after surgery. Results: The study sample resulted in 140 patients. Eighty-seven of them (63.14%) underwent hip replacement surgery, and 53 patients (37.86%) underwent internal fixation surgery. The greater part of the sample (68.42%) had surgery within 48 hours. Patients with more comorbidities had worse clinical outcomes, as shown by the Barthel Index, timing of verticalization and walking, and pain control. Between admission and discharge, the Barthel Index score improved, as did the pain complained of by most patients. Conclusions: A direct connection between orthopedics and the rehabilitation team, even after discharge, should be established and promptly organized to gain the best clinical outcomes. Indeed, we propose the triad early verticalization, pain control, and Barthel Index as a possible tool to define functional quality outcomes in post hip fracture surgery

The Padel phenomenon after the COVID-19: an Italian cross-sectional survey of post-lockdown injuries

The impact of COVID-19 on sport and physical activity has been a subject of considerable interest and concern. Padel satisfies the desire for social interaction and a return to sport after a period of inactivity. The aim of this study is to show a correlation between return to sport and related injuries in a population of Padel players. The study was carried out in a survey mode, consisting of a questionnaire with four sections and fifty questions on the biographical data of the individual, lifestyle before and after the pandemic, knowledge and playing level of Padel and injuries. The self-administered online questionnaire was developed and validated by a panel of physiotherapists, orthopaedic surgeons, and physiatrists with experience in clinical practice and/or musculoskeletal research. The study was conducted in a survey mode from a smartphone or computer via a link to a multiple-choice document. The link to the questionnaire was distributed via mailing lists, social media, and chat applications

Structural Connectivity-Based Parcellation of the Dopaminergic Midbrain in Healthy Subjects and Schizophrenic Patients

Background and objectives: Functional deregulation of dopaminergic midbrain regions is a core feature of schizophrenia pathophysiology. Anatomical research on primates suggests that these regions may be subdivided into distinct, topographically organized functional territories according to their connectivity to the striatum. The aim of the present work was the reconstruction of dopaminergic midbrain subregions in healthy subjects and schizophrenic patients and the evaluation of their structural connectivity profiles. Materials and Methods: A hypothesis-driven connectivity-based parcellation derived from diffusion tractography was applied on 24 healthy subjects and 30 schizophrenic patients to identify distinct territories within the human dopaminergic midbrain in vivo and non-invasively. Results: We identified a tripartite subdivision of dopaminergic midbrain, including limbic, prefrontal and sensorimotor territories. No significant differences in structural features or connectivity were found between subjects and patients. Conclusions: The parcellation scheme proposed herein may help to achieve detailed characterization of structural and functional anomalies of the dopaminergic midbrain in schizophrenic patients

Association between pain, arthropathy and health-related quality of life in patients suffering from acromegaly. A cross-sectional study

Introduction: Despite successful therapy, acromegalic patients have reduced health-related quality of life (HRQoL) compared to healthy controls. Finding predictors of poor HRQoL can be crucial to improving these patients’ global health state. Aim: The primary objective of the study was to find out predictors of HRQoL. Secondary objectives were: (I) to determine correlations with AcroQoL subscales, and (II) to identify predictors for subscales. Materials and methods: In this cross-sectional study conducted in 2019 at the Messina Policlinic Hospital, 45 acromegalic patients were assessed at the Physical and Rehabilitative Medicine Ambulatory. During routine outpatient clinic attendances, the following questionnaires were administered: Acromegaly Quality of Life Questionnaire (AcroQoL), Patient-Assessed Acromegaly Symptom Questionnaire (PASQ), and Western Ontario and McMaster Universities Arthritis Index (WOMAC). We furthermore included the following variables obtained by medical record review: age, BMI, disease duration, previous surgery (Yes/No), previous radiotherapy (Yes/No), use of GH lowering medications (Yes/No), hypertension (Yes/No), diabetes mellitus (Yes/No), and biochemical control of the disease (Yes/No): immunoradiometric assays were employed to serum GH and IGF-1 measurements to identify biochemical control of the disease. Correlation between outcome measures and AcroQoL has been performed. Pearson’s r was calculated for continuous data following normal distribution (AcroQoL, PASQ, AcroQoL-B, AcroQoL-R, WOMAC-P), while Spearman’s rank order correlation was calculated for non-normally distributed data (WOMAC, WOMAC-F, WOMAC-S, AcroQoL-P) and point-biserial correlation for binary variables (biochemically controlled disease, use of GH lowering medications, radiotherapy, surgery). The same correlation analysis was performed for the AcroQoL subscales. Multiple linear regression with backwards, stepwise analysis was used to assess the influence on AcroQoL of correlated variables. Results: AcroQoL was strongly negatively correlated with PASQ (r=−0.700, p<0.001) and negatively correlated with WOMAC [rs (43)=−0.530, p<0.001] and among WOMAC subscales with WOMAC-Physical fitness [rs (43)=−0.518, p<0.001] WOMAC-Pain [r (43)=−0.428, p=0.003], WOMAC-Stiffness [rs (43)=−0.393, p=0.007], and radiotherapy [r (43) =−0.314, p=0.035]. After univariate stepwise regression, PASQ was the strongest independent predictor of AcroQoL, with R2 of 0.392 [F (1,43)=27.695, p<0.001]. Conclusions: This study shows that the severity of painful symptoms is the most important predictor of HRQoL in patients with acromegaly; at the same time, acromegalic arthropathy leads to pain and to a variable amount of functional impairment, exerting great impact on the patient’s perception of his health status. Measure of the progression of arthropathy and symptomatic management could lead to a great HRQoL benefit
