Molecular Changes in the Ischemic Brain as Non-Invasive Brain Stimulation Targets-TMS and tDCS Mechanisms, Therapeutic Challenges, and Combination Therapies.

Ischemic stroke is one of the leading causes of death and disability. As the currently used neurorehabilitation methods present several limitations, the ongoing research focuses on the use of non-invasive brain stimulation (NIBS) techniques such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS). NIBS methods were demonstrated to modulate neural excitability and improve motor and cognitive functioning in neurodegenerative diseases. However, their mechanisms of action are not fully elucidated, and the clinical outcomes are often unpredictable. This review explores the molecular processes underlying the effects of TMS and tDCS in stroke rehabilitation, including oxidative stress reduction, cell death, stimulation of neurogenesis, and neuroprotective phenotypes of glial cells. A highlight is put on the newly emerging therapeutic targets, such as ferroptotic and pyroptotic pathways. In addition, the issue of interindividual variability is discussed, and the role of neuroimaging techniques is investigated to get closer to personalized medicine. Furthermore, translational challenges of NIBS techniques are analyzed, and limitations of current clinical trials are investigated. The paper concludes with suggestions for further neurorehabilitation stroke treatment, putting the focus on combination and personalized therapies, as well as novel protocols of brain stimulation techniques.

The Role of Glia in Wilson's Disease: Clinical, Neuroimaging, Neuropathological and Molecular Perspectives.

Wilson's disease (WD) is inherited in an autosomal recessive manner and is caused by pathogenic variants of the ATP7B gene, which are responsible for impaired copper transport in the cell, inhibition of copper binding to apoceruloplasmin, and biliary excretion. This leads to the accumulation of copper in the tissues. Copper accumulation in the CNS leads to the neurological and psychiatric symptoms of WD. Abnormalities of copper metabolism in WD are associated with impaired iron metabolism. Both of these elements are redox active and may contribute to neuropathology. It has long been assumed that among parenchymal cells, astrocytes have the greatest impact on copper and iron homeostasis in the brain. Capillary endothelial cells are separated from the neuropil by astrocyte terminal legs, putting astrocytes in an ideal position to regulate the transport of iron and copper to other brain cells and protect them if metals breach the blood-brain barrier. Astrocytes are responsible for, among other things, maintaining extracellular ion homeostasis, modulating synaptic transmission and plasticity, obtaining metabolites, and protecting the brain against oxidative stress and toxins. However, excess copper and/or iron causes an increase in the number of astrocytes and their morphological changes observed in neuropathological studies, as well as a loss of the copper/iron storage function leading to macromolecule peroxidation and neuronal loss through apoptosis, autophagy, or cuproptosis/ferroptosis. The molecular mechanisms explaining the possible role of glia in copper- and iron-induced neurodegeneration in WD are largely understood from studies of neuropathology in Parkinson's disease and Alzheimer's disease. Understanding the mechanisms of glial involvement in neuroprotection/neurotoxicity is important for explaining the pathomechanisms of neuronal death in WD and, in the future, perhaps for developing more effective diagnostic/treatment methods.

Is there a connection between spine alignment, chest mobility, shoulder joint and respiratory parameters of patients with ankylosing spondylitis?

INTRODUCTION: Ankylosing spondylitis is chronic progressive disease, which decrease functions of musculoskeletal system including chest area. Those changes influences respiratory mechanics, worsen conditions of proper ventilation of lungs. OBJECTIVES: Rating of functional and respiratory parameters and dependence between them at patients with ankylosing spondylitis. MATERIALS & METHODS: The study included 45 patients with diagnosed ankylosing spondylitis. Chest and upper limbs mobility, resting spinal curvature alignment were assessed, and respiratory parameters were measured in a plethysmographic chamber JAGGER MasterScreen Body. RESULTS: Ankylosing spondylitis patients had lower respiratory parameters especially sReff, and FRC. Restriction of chest and upper limbs mobility was also demonstrated. Forward head extension was observed based on the occipital wall test. Correlations between functional parameters and correlations between functional and respiratory parameters were shown, in particular MIP, MEP, sReff, Rtot, TLC, ERV. CONCLUSIONS: The study confirmed a decrease in functional and respiratory parameters in the examined patients with ankylosing spondylitis compared to the applicable standards. A significant relationship was found between functional parameters in the upper body and respiratory parameters, which worsen with increasing thoracic dysfunction. The obtained results indicate the directions of therapy that should be taken into account to improve respiratory parameters and reduce respiratory dysfunction in these patients. Chest-focused physiotherapy appears to be an important element in improving function in patients with ankylosing spondylitis.

Factors associated with employment of powered wheelchair users.

Purpose: To identify correlations between demographic, health-related, environmental factors and the employment status of power wheelchair (PWC) users.Method: We retrospectively analysed semi-structured interviews with 128 participants, their assistants or family members, and the participant's provided medical records. Participants were adult PWC users who applied for grants in purchasing a new PWC for gaining or keeping employment between 2019-2021 in Mazovian Province, Poland.Results: Forty-six PWC users (35.9%) were employed while applying for the financial support programme. Fischer's Exact Test of Independence identified positive correlations between employment and education level (p < 0.001), residing in an urban area (p = 0.02), being employed before starting PWC use (p < 0.001), having vocational rehabilitation (p < 0.001), and living in a relationship (p = 0.002). There were no associations between employment status and sex, age at study entry, age at disability onset, living alone or with others, duration of PWC use, or full or part-time PWC use. Our findings indicate that PWC users are at risk of non-employment and financial hardship. This research may support policies for PWC provision that would support gainful employment. The results show that access to quality education, vocational rehabilitation, and perhaps the physical/emotional support from others in close relationships matter. These aspects should be considered in educational policies, transportation, and physical environmental accessibility for PWC users, supporting their gainful employment.

Paid employment is recognised for its positive impact on the financial situation, health, and overall life satisfaction of power wheelchair users. Rehabilitation professionals can play a crucial role in facilitating the attainment and maintenance of employment throughout the clinical process.Educating power wheelchair users with factors conducive to supporting their employment, such as pursuing advanced education, utilising vocational rehabilitation services, residing in urban areas, fostering meaningful social relationships, and drawing upon previous employment experiences, may improve outcomes.Sex, age, disability cause, duration of disability, and reliance on a power wheelchair as the primary mode of mobility were found to be unrelated to employment status among power wheelchair users.Further investigation into the needs of the power wheelchair user population in their pursuit of gainful employment is justified.

A Study of Polish Family with Scoliosis and Limb Contractures Expands the MYH3 Disease Spectrum.

A disease associated with malfunction of the MYH3 gene is characterised by scoliosis, contractures of the V fingers, knees and elbows, dysplasia of the calf muscles, foot deformity and limb length asymmetry. The aim of this study was to identify the cause of musculoskeletal deformities in a three-generation Polish family by exome sequencing. The segregation of the newly described c.866A>C variant of the MYH3 gene in the family indicates an autosomal dominant model of inheritance. The detected MYH3 variant segregates the disease within the family. The presented results expand the MYH3 disease spectrum and emphasize the clinical diagnostic challenge in syndromes harbouring congenital spine defects and joint contractures.

Can the Initial Parameters of Functional Scales Predict Recovery in Patients with Complete Spinal Cord Injury? A Retrospective Cohort Study.

Regaining greater independence in performing daily activities constitutes a priority for people with tetraplegia following spinal cord injury (SCI). The highest expectations are connected with the improvement of hand function. Therefore, it is so important for the clinician to identify reliable and commonly applicable prognostic factors for functional improvement. The aim of this study was to conduct an analysis to assess the impact of initial functional factors on the clinical improvement in patients during early neurological rehabilitation (ENR). This study assessed 38 patients with complete SCI aged 17-78 who underwent ENR in 2012-2022. The analysis included the motor score from the AIS (MS), the Barthel Index (BI) and the SCIM scale values at the beginning of the ENR program and after its completion. During ENR, patients achieved a statistically significant improvement in MS, BI and SCIM. The initial MS and the level of neurological injury constituted the predictors of functional improvement during ENR. Significant statistical relationships were observed primarily in the correlations between the initial MS and BI, and the increase in the analyzed functional scales of SCI patients. Higher initial MS may increase the chances of a greater and faster functional improvement during ENR.

Impact of Robotic-Assisted Gait Therapy on Depression and Anxiety Symptoms in Patients with Subacute Spinal Cord Injuries (SCIs)-A Prospective Clinical Study.

BACKGROUND: Mood disorders, especially depression, and emotional difficulties such as anxiety are very common problems among patients with spinal cord injuries (SCIs). The lack of physical training may deteriorate their mental state, which, in turn, has a significant impact on their improvement in functioning. The aim of the present study was to examine the influence of innovative rehabilitation approaches involving robotic-assisted gait therapy (RAGT) on the depression and anxiety symptoms in patients with SCI. METHODS: A total of 110 participants with subacute SCIs were enrolled in this single-center, single-blinded, single-arm, prospective study; patients were divided into experimental (robotic-assisted gait therapy (RAGT)) and control (conventional gait therapy with dynamic parapodium (DPT)) groups. They received five training sessions per week over 7 weeks. At the beginning and end of therapy, the severity of depression was assessed via the Depression Assessment Questionnaire (KPD), and that of anxiety symptoms was assessed via the State-Trait Anxiety Inventory (STAI X-1). RESULTS: SCI patients in both groups experienced significantly lower levels of anxiety- and depression-related symptoms after completing the seven-week rehabilitation program (KPD: Z = 6.35, p < 0.001, r = 0.43; STAI X-1: Z = -6.20, p < 0.001, r = 0.42). In the RAGT group, post-rehabilitation measurements also indicated an improvement in psychological functioning (i.e., decreases in depression and anxiety and an increase in self-regulation (SR)). Significant results were noted for each variable (STAI X-1: Z = -4.93; KPD: Z = -5.26; SR: Z = -3.21). In the control group, there were also decreases in the effects on depression and state anxiety and an increase in self-regulation ability (STAI X-1: Z = -4.01; KPD: Z = -3.65; SR: Z = -2.83). The rehabilitation modality did not appear to have a statistically significant relationship with the magnitude of improvement in the Depression Assessment Questionnaire (KPD) (including self-regulation) and State-Trait Anxiety Inventory (STAI) scores. However, there were some significant differences when comparing the groups by the extent and depth of the injury and type of paralysis. Moreover, the study did not find any significant relationships between improvements in physical aspects and changes in psychological factors. CONCLUSIONS: Subjects in the robotic-assisted gait therapy (RAGD) and dynamic parapodium training (DPT) groups experienced decreases in anxiety and depression after a 7-week rehabilitation program. However, the rehabilitation modality (DPT vs. RAGT) did not differentiate between the patients with spinal cord injuries in terms of the magnitude of this change. Our results suggest that individuals with severe neurological conditions and complete spinal cord injuries (AIS A, according to the Abbreviated Injury Scale classification) may experience greater benefits in terms of changes in the psychological parameters after rehabilitation with RAGT.

Cardiac involvement in polymyositis and dermatomyositis: diagnostic approaches.

Polymyositis (PM) and dermatomyositis (DM) are rare idiopathic inflammatory myopathies (IIM). Myocardial involvement in patients with IIM is an unfavorable prognostic factor and one of the most common cause of mortality in this group of patients. The purpose of this review is to present current knowledge on cardiovascular manifestations observed in IIM. Data published in English until December 2021 were selected. Clinical symptoms suggesting cardiac involvement are non-specific and require a differential diagnosis in accordance with cardiological guidelines. Troponin I is specific to cardiac injury and should be preferred to other markers to evaluate the myocardium in IIM. Abnormalities in electrocardiography are common in IIM, especially non-specific changes of the ST-T segment. In standard echocardiography left ventricular diastolic dysfunction is reported frequently. New diagnostic technologies can reveal clinically silent myocardial abnormalities. However, the prognostic value of subclinical impairment of myocardial function require further studies.

Impact of Robotic-Assisted Gait Training in Subacute Spinal Cord Injury Patients on Outcome Measure.

The improvement of walking ability is a primary goal for spinal cord injury (SCI) patients. Robotic-assisted gait training (RAGT) is an innovative method for its improvement. This study evaluates the influence of RAGT vs. dynamic parapodium training (DPT) in improving gait motor functions in SCI patients. In this single-centre, single-blinded study, we enrolled 105 (39 and 64 with complete and incomplete SCI, respectively) patients. The investigated subjects received gait training with RAGT (experimental S1-group) and DPT (control S0-group), with six training sessions per week over seven weeks. The American Spinal Cord Injury Association Impairment Scale Motor Score (MS), Spinal Cord Independence Measure, version-III (SCIM-III), Walking Index for Spinal Cord Injury, version-II (WISCI-II), and Barthel Index (BI) were assessed in each patient before and after sessions. Patients with incomplete SCI assigned to the S1 rehabilitation group achieved more significant improvement in MS [2.58 (SE 1.21, p < 0.05)] and WISCI-II [3.07 (SE 1.02, p < 0.01])] scores in comparison with patients assigned to the S0 group. Despite the described improvement in the MS motor score, no progression between grades of AIS (A to B to C to D) was observed. A nonsignificant improvement between the groups for SCIM-III and BI was found. RAGT significantly improved gait functional parameters in SCI patients in comparison with conventional gait training with DPT. RAGT is a valid treatment option in SCI patients in the subacute phase. DPT should not be recommended for patients with incomplete SCI (AIS-C); in those patients, RAGT rehabilitation programs should be taken into consideration.

Neurological Wilson's Disease Signs-Hepatic Encephalopathy or Copper Toxicosis?

Wilson's disease (WD) is a rare autosomal recessive (AR) disorder resulting from mutations in the ATP7B gene, which is responsible for the encryption of transmembrane copper transporting ATPase. The symptomatic presentation of the disease is estimated to be about 1 in 30,000. The impairment of ATP7B function results in a copper overload in hepatocytes, which further leads to liver pathology. This copper overload also occurs in other organs, most particularly in the brain. This could then cause the occurrence of neurological and psychiatric disorders. Symptoms differ substantially and most often occur between the ages of 5 and 35 years. Early symptoms are commonly hepatic, neurological, or psychiatric. While disease presentation is most often asymptomatic, it could also range as far as to include fulminant hepatic failure, ataxia, and cognitive disorders. Various treatments are available for Wilson's disease, including chelation therapy and zinc salts, which can reverse copper overload through different mechanisms. In select cases, liver transplantation is recommended. New medications, such as tetrathiomolybdate salts, are currently being investigated in clinical trials. With prompt diagnosis and treatment, prognosis is favorable; however, diagnosing patients before the onset of severe symptoms is a significant concern. Early screening for WD could help in diagnosing patients earlier and improving treatment outcomes.

Prophylaxis of occipital pressure sores in patients after elective spinal surgery in a pandemic condition.

Background: Occipital pressure sores (OPS) are complications of the use of cervical collars. Prophylaxis of OPS in patients after cervical spinal surgery (CCS) appears to be neglected. Material and methods: Cochrane Central, EMBASE, PubMed, SCOPUS, and Web of Science databases were searched for studies on OPS after CCS. Results: We present the case of a patient with rheumatic arthritis who was secured with a hard collar after revision CCS and was not seen by a health professional due to the COVID-19 outbreak. The result was an OPS leading to deep tissue infection. The patient required a prolonged hospital stay and long-term antibiotic therapy. We found a lack of literature on OPS prevention in patients after CCS. Conclusions: Patients with rheumatoid arthritis using collars after CCS are at risk of OPS. Protocols of prevention of OPS should be reviewed with respect to challenges resulting from epidemiological restrictions and accessibility of telemedical technologies.

Cognitive and Physical Intervention in Metals' Dysfunction and Neurodegeneration.

Metals-especially iron, copper and manganese-are important elements of brain functions and development. Metal-dysregulation homeostasis is associated with brain-structure damage to the motor, cognitive and emotional systems, and leads to neurodegenerative processes. There is more and more evidence that specialized cognitive and motor exercises can enhance brain function and attenuate neurodegeneration in mechanisms, such as improving neuroplasticity by altering the synaptic structure and function in many brain regions. Psychological and physical methods of rehabilitation are now becoming increasingly important, as pharmacological treatments for movement, cognitive and emotional symptoms are limited. The present study describes physical and cognitive rehabilitation methods of patients associated with metal-induced neurotoxicity such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease and Wilson's disease. In our review, we describe physical (e.g., virtual-reality environments, robotic-assists training) and psychological (cognitive training, cognitive stimulation, neuropsychological rehabilitation and cognitive-behavioral and mindfulness-based therapies) methods, significantly improving the quality of life and independence of patients associated with storage diseases. Storage diseases are a diverse group of hereditary metabolic defects characterized by the abnormal cumulation of storage material in cells. This topic is being addressed due to the fact that rehabilitation plays a vital role in the treatment of neurodegenerative diseases. Unfortunately so far there are no specific guidelines concerning physiotherapy in neurodegenerative disorders, especially in regards to duration of exercise, type of exercise and intensity, as well as frequency of exercise. This is in part due to the variety of symptoms of these diseases and the various levels of disease progression. This further proves the need for more research to be carried out on the role of exercise in neurodegenerative disorder treatment.

Psychometric validation of the Polish version of the Central Sensitization Inventory in subjects with chronic spinal pain.

BACKGROUND: Central sensitization is an amplification of neuronal signaling within the central nervous system. The Central Sensitization Inventory was introduced in 2012. A Polish version of the CSI (CSI-Pol) was developed in 2019, but it was not psychometrically validated. The aim of this study was to validate the CSI-Pol in a sample of Polish-speaking patients with chronic spinal pain and compare them with a group of healthy control subjects. METHODS: The CSI-Pol was administered to 151 patients with chronic spinal pain recruited from two centers. It was re-administered 7 days later. The psychometric properties were then evaluated, including test-retest reliability, construct validity, factor structure and internal consistency. We correlated the CSI-Pol with functional scales, depression and social support scales and compared CSI-Pol scores in the clinical subjects with 30 healthy control subjects recruited from medical staff and their families. RESULTS: The CSI-Pol demonstrated excellent internal consistency (Cronbach's α =0,933) and test-retest reliability (Intraclass Correlation Coefficients - ICC =0.96), as well as significant positive associations with other patient-reported scales, including the Neck Disability Index (r = 0.593), Revised Oswestry Low Back Pain Disability Questionnaire (r = 0.422), and other measures of functional and depressive states. An exploratory factor analysis resulted in a 4-factor model. CSI-Pol scores in the clinical sample (35.27 ± 17.25) were significantly higher than the control sample (23.3 ± 8.9). CONCLUSION: The results of this study suggest that the CSI-Pol may be a useful clinical tool for assessing central sensitization related symptoms and guiding appropriate treatment in Polish-speaking patients with spinal pain.

Temporomandibular joint disorders in patients with rheumatoid arthritis.

OBJECTIVES: The aim of this study is to draw the attention of patients, doctors and therapists to the importance of temporomandibular joint (TMJ) problems in rheumatoid arthritis (RA). MATERIAL AND METHODS: The research was conducted at the National Institute of Geriatrics Rheumatology and Rehabilitation in Warsaw. The study involved 60 subjects. The test group consists of 30 patients with diagnosed RA. The control group (n = 30) consisted of healthy participants of similar age. The study analyzed the occurrence of problems in TMJ joints, acoustic phenomena and the level of pain. Masseter muscle development, range of abduction motion and pain during palpation of soft tissues were assessed on the basis of the joint pain map of Prof. Mariano Rocabado. RESULTS: In the RA group, more than half (56.7%) had problems with the TMJ, 70% of them had masseter hypertrophy and clicks in the TMJ, and 46.7% had tinnitus (in the control group: 10%, 30%, and 30%, respectively). Patients also had a limited range of abduction movement in the TMJ (38.0 ±6.1 mm). Analysis of the pain map of Prof. Mariano Rocabado in RA patients indicates a significantly greater number of pain structures. In the control group no pain was observed in structures such as the posterosuperior synovial and bilaminar zone, posterior ligament, or retrodiscal area. CONCLUSIONS: Temporomandibular joint problems in RA patients were more serious than in the control group and these differences were statistically significant for most tests. The awareness of the problem with the TMJ in RA patients is very low; participants of our study were 100% unaware that the function of the TMJ could be improved. Additionally, there are no guidelines for the treatment and rehabilitation of these joints.

Systemic lupus erythematosus and critical illness polyneuropathy.

Systemic lupus erythematosus (SLE) is a chronic disease of connective tissue with multi-organ involvement. Manifestation in the nervous system is one of the most difficult symptoms to assess and interpret. The aim of the study is to indicate diagnostic problems in patients with SLE in whom neurological symptoms are present at the time of diagnosis of SLE but also with complications that occurred after diagnosis. In the presented case, the appearance of flaccid tetraparesis with areflexia suggested peripheral damage to the nervous system. In the electromyography performed in this patient, acute axonal polyneuropathy was mainly suspected. Further differential diagnosis should consider other acute and subacute developing polyneuropathies. Guillain-Barré polyneuropathy deserves special attention. To our knowledge, this is the first case documented in the literature of the coexistence of critical illness polyneuropathy and SLE.

Copper, Iron, and Manganese Toxicity in Neuropsychiatric Conditions.

Copper, manganese, and iron are vital elements required for the appropriate development and the general preservation of good health. Additionally, these essential metals play key roles in ensuring proper brain development and function. They also play vital roles in the central nervous system as significant cofactors for several enzymes, including the antioxidant enzyme superoxide dismutase (SOD) and other enzymes that take part in the creation and breakdown of neurotransmitters in the brain. An imbalance in the levels of these metals weakens the structural, regulatory, and catalytic roles of different enzymes, proteins, receptors, and transporters and is known to provoke the development of various neurological conditions through different mechanisms, such as via induction of oxidative stress, increased α-synuclein aggregation and fibril formation, and stimulation of microglial cells, thus resulting in inflammation and reduced production of metalloproteins. In the present review, the authors focus on neurological disorders with psychiatric signs associated with copper, iron, and manganese excess and the diagnosis and potential treatment of such disorders. In our review, we described diseases related to these metals, such as aceruloplasminaemia, neuroferritinopathy, pantothenate kinase-associated neurodegeneration (PKAN) and other very rare classical NBIA forms, manganism, attention-deficit/hyperactivity disorder (ADHD), ephedrone encephalopathy, HMNDYT1-SLC30A10 deficiency (HMNDYT1), HMNDYT2-SLC39A14 deficiency, CDG2N-SLC39A8 deficiency, hepatic encephalopathy, prion disease and "prion-like disease", amyotrophic lateral sclerosis, Huntington's disease, Friedreich's ataxia, and depression.

Relationship Between Level of Economic Development, Age, and Etiology of Spinal Cord Injury: A Cross-Sectional Survey From 22 Countries.

OBJECTIVE: To examine relationships between age and spinal cord injury (SCI) and cause of SCI and how this depends on economic development. DESIGN: Cross-sectional survey. SETTING: Community, 22 countries representing all stages of economic development. PARTICIPANTS: A total of 12,591 adults with SCI (N=12,591). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Interactions between age at injury and gross domestic product per capita based on purchasing power parity (GDP PPP) quartiles calculated with the application of logistic regression with the Maximum Likelihood estimator. Independence between SCI cause and age was assessed with the Wald test. RESULTS: In persons with traumatic SCI, younger age was associated with a higher likelihood of injury in motor vehicle collisions, whereas older individuals had a greater chance of SCI due to falls. Associations between increased likelihood of high-energy traumatic SCI and younger age, low-energy traumatic SCI with older age, nontraumatic SCI with older age in persons injured in adulthood, and a higher prevalence of incomplete SCI lesions in individuals injured at an older age were revealed. Higher GDP PPP influenced positively the likelihood of low-energy SCI in older individuals and was negatively associated with the chance of sustaining SCI in motor vehicle collisions and the likelihood of having nontraumatic SCI at an older age. CONCLUSIONS: SCI in older age is predominantly because of falls and nontraumatic injuries. Higher country income is associated with an increased proportion of SCI sustained later in life because of low-energy trauma involving cervical injury and a lower chance of being because of motor vehicle collisions. An increased prevalence of nontraumatic SCI in older individuals associated with lower country income may reflect a higher exposure to socially preventable conditions and lower access to or efficacy of health care. Future studies on etiology of SCI should make the distinction between low and high falls and overcome underrepresentation of older persons.

Adherence to prescriptions of therapeutic exercises in patients with traumatic spinal cord injury.

INTRODUCTION: Spinal cord injury (SCI), which disrupts motor, sensory and autonomic functions, causes significant changes in the functioning of an individual. It is believed that most of the conditions secondary to SCI, i.e. osteoporosis, spasticity or cardiopulmonary diseases, are associated with immobility. The aim of the study is to assess the adherence to prescriptions of therapeutic exercises (APTE) in patients with SCI after acute phases of rehabilitation. MATERIAL AND METHODS: The criterionfor APTE recognition was the performance at least twice a week for a minimum of 30 minutes of active exercises with resistance, and exercises maintaining the range of movement of the joints The research tools were own questionnaire and the WHOQOL-BREF scale. RESULTS: 46 subjects (63.9%) met the APTE criteria. The most frequent place for performing the exercises was the subject's home with 43 subjects (93.5%) with APTE performed the exercises in their homes. 17 subjects (36.9%) with APTE performed exercises during stays at various rehabilitation centres. The main cause for the lack of APTE was the limited availability of facilities considered necessary by the respondents to adhere to the instructions. In statistical analysis, the level of neurological injury correlated with meeting the APTE criteria. It was discovered that a subjective assessment of the exercise dose correlated with the place where the exercises were performed, but did not correlate with meeting the APTE criteria. CONCLUSIONS: The basic place for performing exercises (as instructed in hospital) was the subject's home. Limited access to reimbursed environmental therapy resulted in an increased cost of exercises supervised by commercially-employed physiotherapists. The current gaps in the system of supervision and counselling of subjects post-SCI necessitate changes in the Polish health care system.

What do physiotherapists and physiotherapy students know about autonomic dysreflexia?

CONTEXT/OBJECTIVE: Autonomic dysreflexia (AD) is an emergency condition typical for individuals with spinal cord injury (SCI). Adequate health professionals' knowledge of AD is important for the effective and safe rehabilitation of persons with SCI. The purpose of the study is to assess the knowledge of AD in undergraduate and postgraduate physiotherapists. The data gained will be useful for better addressing of AD in clinical practice. DESIGN: An observational study. SETTING: Rehabilitation College in Warsaw, Medical University of Warsaw, Poland. PARTICIPANTS: 52 undergraduate and 68 postgraduate physiotherapists. INTERVENTION: AD knowledge testing. OUTCOME MEASURES: A test assessing knowledge of causality and consequences of AD created at the Medical University of Warsaw. RESULTS: No significant differences in test scores between under- and postgraduates were found (P = 0.09). Higher scores were noted in physiotherapy masters as compared to bachelors (P = 0.01), in participants who have an in-patient practice (P = 0.04), a practice longer than 5 years (P = 0.02) and those who see patients with SCI more frequently (P = 0.01). A self-assessed knowledge of AD was admitted as poor or none by 96.2% of undergraduates and 86.8% of postgraduates. CONCLUSION: In the studied population the knowledge of causality and consequences of AD presented by undergraduate and postgraduate physiotherapists was low. Lower test scores were associated with a lower level of professional education achieved, having an outpatient practice only and having fewer patients with spinal cord injury. Efforts should be made to improve undergraduate and postgraduate education on AD of physiotherapists.

Copper Dyshomeostasis in Neurodegenerative Diseases-Therapeutic Implications.

Copper is one of the most abundant basic transition metals in the human body. It takes part in oxygen metabolism, collagen synthesis, and skin pigmentation, maintaining the integrity of blood vessels, as well as in iron homeostasis, antioxidant defense, and neurotransmitter synthesis. It may also be involved in cell signaling and may participate in modulation of membrane receptor-ligand interactions, control of kinase and related phosphatase functions, as well as many cellular pathways. Its role is also important in controlling gene expression in the nucleus. In the nervous system in particular, copper is involved in myelination, and by modulating synaptic activity as well as excitotoxic cell death and signaling cascades induced by neurotrophic factors, copper is important for various neuronal functions. Current data suggest that both excess copper levels and copper deficiency can be harmful, and careful homeostatic control is important. This knowledge opens up an important new area for potential therapeutic interventions based on copper supplementation or removal in neurodegenerative diseases including Wilson's disease (WD), Menkes disease (MD), Alzheimer's disease (AD), Parkinson's disease (PD), and others. However, much remains to be discovered, in particular, how to regulate copper homeostasis to prevent neurodegeneration, when to chelate copper, and when to supplement it.
