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
Quadriceps Muscle and Medial Retinaculum Combinate Effects on Patellar Instability during Knee Flexion
Background: Patellar instability can cause pain and disability. A finite element model of a healthy human knee was performed to analyze the role of quadriceps and medial retinaculum imbalance in patellar instability. Methods: The model was created by matching magnetic resonance and computed tomography images of a normal adult patient’s knee. Muscle force intensities were calculated by static optimization, considering the lower limb muscles, knee movement and the ground reaction during walking. Patellar instability was experimentally generated by progressively uncoupling muscular forces, (90 N versus 110 N), while at the same time, the load derived from the quadriceps was gradually reduced by 20%. Results: This loss in force symmetry of 10 N on the retinaculum may produce a displacement of approximately 7 mm, with an increase in patellar contact forces of approximately 44%. When the quadriceps force is reduced by 10% and the unbalanced medial retinaculum acts together, the displacements are in the order of 14 mm, and the patellar contact forces increase by 84%. Conclusion: A reduced quadriceps force alone is not able to cause significant patellar instability, while an imbalance of forces at the level of the retinaculum could lead to patellar instability, especially when the two effects are combined. A better understanding of joint relationships and muscle synergies can help to improve clinical approaches to patella instabilit
Whole Body Cryostimulation: A New Adjuvant Treatment in Central Sensitization Syndromes? An Expert Opinion
Central sensitisation is defined as a multifactorial etiopathogenetic condition involving an increase in the reactivity of nociceptive neurons and alterations in pain transmission and perception in the central nervous system. Patients may present with widespread chronic pain, fatigue, sleep disturbance, dizziness, psychological (e.g., depression, anxiety, and anger) and social impairment. Pain can be spontaneous in onset and persistence, characterised by an exaggerated response and spread beyond the site of origin, and sometimes triggered by a non-painful stimulus. Whole-body cryostimulation (WBC) could be an adjuvant therapy in the management of this type of pain because of its global anti-inflammatory effect, changes in cytokines and hormone secretion, reduction in nerve conduction velocity, autonomic modulation, and release of neurotransmitters involved in the pain pathway. In several conditions (e.g., fibromyalgia, rheumatoid arthritis, and chronic musculoskeletal pain), WBC affects physical performance, pain perception, and psychological aspects. Given its multiple targets and effects at different organs and levels, WBC appears to be a versatile adjuvant treatment for a wide range of conditions of rehabilitation interest. Further research is needed to fully understand the mechanisms of analgesic effect and potential actions on pain pathways, as well as to study long-term effects and potential uses in other chronic pain conditions
Short- and Midterm Comparison of Platelet-Rich Plasma with Hyaluronic Acid versus Leucocyte and Platelet-Rich Plasma on Pain and Function to Treat Hip Osteoarthritis. A Retrospective Study
Hip osteoarthritis (HOA) leads to pain and reduced function. The use of intra-articular injections based on corticosteroids, platelet-rich plasma (PRP), or hyaluronic acid (HA) is becoming a common symptomatic therapy for HOA. For the first time, we compare the effectiveness of plasma with a high concentration of platelets and leukocytes (L-PRP) with PRP+HA in patients with mild to moderate HOA. A total of 26 patients in each group were administered with either L-PRP or PRP+HA. Outcomes were evaluated at baseline, 3 months, and 1 year after the injection. The mean visual analog scale (VAS) and Harris hip score (HHS) within and between groups among different time points were compared using repeated measures ANCOVA (age set as a covariate). Both treatments were effective in reducing VAS, but not in significantly increasing HHS. In the group treated with L-PRP, VAS showed interaction between time and treatment (in favor of L-PRP). Pairwise comparison for treatment and time point evidenced a significant difference at 1-year follow-up between L-PRP and PRP-HA. Outcomes support the idea that both treatments may be effective in reducing pain, with maximal pain reduction achieved after 3 months. L-PRP showed better results in reducing VAS over time. Both treatments are effective at reducing pain in the short to medium term. L-PRP could be the treatment of choice due to a more marked effect over time. Nevertheless, further research is needed to better describe the clinical outcome of these formulations
Platelet-Rich Plasma Combined with Hyaluronic Acid versus Leucocyte and Platelet-Rich Plasma in the Conservative Treatment of Knee Osteoarthritis. A Retrospective Study
Background and objectives: Knee osteoarthritis (KO) is one of the most common joint diseases, determining knee pain and reduction of mobility, with a negative effect on quality of life. Intra-articular injections of different formulations of platelet-rich plasma (PRP) are an increasingly common non-surgical treatment for KO. Recently, in order to combine the anti-inflammatory effect of platelet rich plasma and the viscosupplementation effect of hyaluronic acid, a formulation of PRP combined with hyaluronic acid (PRP + HA) has been proposed. The purpose of this study is to retrospectively compare the effectiveness of plasma with high concentration of platelets and leukocytes (L-PRP) with PRP + HA in patients with mild to moderate (Kellgren–Lawrence scale II-III grade) KO. Materials and Methods: Among the 51 patients included, 28 have been treated with L-PRP, while 23 with PRP + HA. A retrospective evaluation at baseline (T0), after 3 months (T1) and 1 year (T2) has been performed. The outcome analyzed are the Knee Society Score (KSS), the Visuo Analogic Scale (VAS) (at T0, T1, and T2) and the Knee Injury and Osteoarthritis Outcome Score (KOOS) (T0 and T2). We evaluated change in mean scores within and between groups among different time points using repeated measures ANCOVA. Results: Although the two treatments have been both effective in reducing VAS, the group treated with PRP + HA showed a significantly lower KSS. Conclusions: Our results show that the use of both treatments may help to reduce pain in patients with mild to moderate KO. PRP + HA showed better results in improving knee mobility and function. These results should be considered only preliminary: Further research is needed to completely describe the clinical effectiveness of these formulations
Whole-Body Cryostimulation in Post-COVID Rehabilitation for Patients with Obesity: A Multidisciplinary Feasibility Study
Background: A post-COVID condition can reduce activity and quality of life, resulting in a significant socioeconomic and health burden. Understanding its impact on patients’ health is important for the development of personalized rehabilitation interventions. An independent association between obesity and post-COVID condition was found because of complications and comorbidities. Methods: Sixteen patients with obesity and post-COVID symptoms (i.e., dyspnea, pain, poor sleep quality, muscle fatigue), admitted to the Istituto Auxologico Italiano, Piancavallo (VB), Italy, were recruited for a four-week rehabilitation program including conventional exercise therapy, nutritional intervention, psychological support and whole-body cryostimulation (WBC). Results: All participants attended all sessions of the program. Anthropometric data showed statistically significant changes in weight, waist circumference and body mass index. Biochemical analyses showed significant reductions in lipid and inflammatory profiles. There was a significant improvement in physical performance, reduction in pain and improvement in psychological well-being. Conclusion: A multidisciplinary rehabilitation protocol including WBC, designed for patients with obesity and a post-COVID condition, is safe and feasible. The overall improvements demonstrate that multidisciplinary rehabilitation was effective on post COVID patients and suggest that the use of WBC is safe and could play a role as a booster in rehabilitation programs
Safety and Efficacy of Hybrid Cooperative Complexes of Sodium Hyaluronate and Sodium Chondroitin for the Treatment of Patients with Symptomatic Knee Osteoarthritis
Abstract Introduction Knee osteoarthritis (KOA) represents a widespread degenerative disease that causes pain and motor disability. Conservative treatments mainly focus on relieving symptoms, improving joint function, and trying to delay surgery. Safety and efficacy of hybrid cooperative complexes (2.4% sodium hyaluronate and 1.6% sodium chondroitin; HA-SC) for symptomatic KOA were investigated in a single-arm, prospective, pilot study. Methods Patients with a visual analogue scale (VAS) pain score ≥ 4 and Kellgren–Lawrence Grade < 4 received a single intraarticular HA-SC injection. Patients with a VAS score change from baseline ≤ 1 received a second injection at day 30. Device-related adverse events (DR-AEs)/adverse events (AEs) were primary endpoints. Secondary endpoints included Western Ontario and McMaster Universities Osteoarthritis Index LK 3.1 (WOMAC LK 3.1), VAS, patient global assessment of disease status (PtGA), and patient proportion needing a second injection. Results Of 83 patients with KOA (Kellgren–Lawrence Grade, 2–3), 34.9% had DR-AEs at day 7. No serious DR-AEs/AEs were reported. A significant (P < 0.0001) reduction over time in VAS pain score plus WOMAC pain, stiffness, physical function limitation, and total scores was reported. Median PtGA scores indicated a ‘slight improvement’ at most follow-up visits. Only 18.1% of patients required a second injection. Conclusions A single intraarticular HA-SC injection was safe, well-tolerated, and did not lead to major deterioration in terms of reducing knee pain, stiffness, and physical function limitation in patients with symptomatic KOA
Cerebellar Atrophy Associated with Primary Sjögren's Syndrome: Diagnosis, Therapy, and Virtual Reality Rehabilitation: A Case Report
Cerebellar involvement in primary Sjögren's syndrome (pSS) is an uncommon condition, with only a limited number of cases described worldwide. A 43-year-old woman affected by cerebellar atrophy associated with pSS was referred to our center to undergo a cycle of physical rehabilitation therapy. Although motor symptoms started when the patient was 23 years of age, the underlying disease remained undiagnosed for several years. Neurological examination before rehabilitation revealed ataxic gait, dysmetria, nystagmus, and hypermetric saccades; the patients complained about unsteadiness while standing or walking. To improve balance and gait abilities, a 20-session cycle of balance rehabilitation, based on a combination of conventional physical therapy and virtual reality exergames, was prescribed. The outcomes of rehabilitation were evaluated with balance tests and three-dimensional (3D) gait analysis. To our knowledge, this is the first case describing the diagnostic workout for cerebellar atrophy associated with pSS and the subsequent motor rehabilitation. This work highlights the importance of early diagnosis and rehabilitation in patients with central nervous system involvement in pSS
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
