Depression is the most common and devastating psychiatric disorder in the world. Its symptoms, especially during the pandemic, are observed in all age groups. Exercise training (ET) is well known as a non-pharmacological strategy to alleviate clinical depression. The brain-derived neurotrophic factor (BDNF) is one of the biological factors whose expression and secretion are intensified in response to ET. BDNF is also secreted by contracted skeletal muscle that likely exerts para-, auto- and endocrine effects, supporting the crosstalk between skeletal muscle and other distant organs/tissues, such as the nervous system. This finding suggests that they communicate and work together to induce improvements on mood, cognition, and learning processes as BDNF is the main player in the neurogenesis, growth, and survival of neurons. Therefore, BDNF has been recognized as a therapeutic factor in clinical depression, especially in response to ET. The underlying mechanisms through which ET impacts depression are varied. The aim of this review was to provide information of the biological markers of depression such as monoamines, tryptophan, endocannabinoids, markers of inflammatory processes (oxidative stress and cytokines) stress and sex hormones and their relationship to BDNF. In addition, we reviewed the effects of ET on BNDF expression and how it impacts depression as well as the potential mechanisms mediating this process, providing a better understanding of underlying ET-related mechanisms in depression.

Stroke is a high-risk factor for depression. Neurological rehabilitation is greatly difficult and often does not include treatment of depression. The post-stroke depression plays an important role in the progress of treatment, health, and the life of the patient. The appropriate treatment of depression could improve the quality of life of the patient and their family. The study aimed to evaluate the impact of physical activity and socio-economic status of the patient on the effectiveness of recovery from depression and the severity of the symptoms of depression. The study was conducted with 40 patients after stroke aged 42–82 years, and included 10 women and 30 men who were hospitalized for two weeks. The severity of depression/anxiety (D/A) symptoms were evaluated two times; at admission and after two weeks of physical therapy. The hospital anxiety and depression scale (HADS) questionnaire was used for this purpose. Socio-economic status was evaluated by several simple questions. It was revealed that physical therapy has a positive influence on mental state. The severity of D/A symptoms after stroke is related to the financial status of the patients (χ² = 11.198, p = 0.024). The state of health (χ² = 20.57, p = 0.022) and physical fitness (χ² = 12.95, p = 0.044) changed the severity of symptoms of anxiety and depressive disorders. The kinesiotherapy in the group of patients with post-stroke depression had positive effects; however, economic and health conditions may influence the prognosis of the disease.

Gait is one of the examined functions in child development. It should be economical and symmetrical. One test increasingly used by physiotherapists and pediatricians is asymmetrical tonic neck reflex (ATNR). Physiologically, it is observed from in utero up to six postnatal months. This reaction is inhibited with the growing maturation of the central nervous system (CNS). In some children, when the natural process of development is incorrect, ATNR manifests later in life, when it is observed as an automatic response of muscle tension to head rotation. Analysis of pelvis symmetry in the gait of children with active ATNR is important for better understanding their specific movements. In the gait of children with persistent ATNR, some variations are observed. The aim of the study was to investigate the gait symmetry of preschool children and the influence of persistent ATNR. Fifty preschool children with a trace form of ATNR were examined. The distribution of the gait parameters was determined using a BTS G-SENSOR measurement instrument. ATNR negatively influences pelvic obliquity and pelvic rotation (p < 0.01). Younger children have a statistically higher symmetry index of pelvis obliquity in the examined group (p = 0.015). Boys obtain a higher result of symmetry in pelvic tilt than girls in the group (p = 0.027). ATNR affects walking symmetry in preschool children, thus evaluation of the reflex activity and then proper therapy is required to support proper development.

Background: Above-knee amputations (AKAs) contribute to gait asymmetry. The level of asymmetry is affected by the type of knee prosthetic module. There is limited evidence suggesting that more technically advanced solutions (microprocessor modules; MicPK) are superior to less advanced ones (mechanical modules; MechPK). The study aimed to evaluate the variable range of hip and pelvic joint movements during gait and look for differentiating areas with an increased level of asymmetry of the gait cycle in individuals who underwent an AKA and are equipped with MicPK or MechPK.Methods: Twenty-eight individuals participated in the study; 14 were assigned to a study group of individuals who underwent a unilateral AKA, and the other 14 were healthy participants as a control group. The movement task was recorded using the optoelectronic SMART-E system following the standard Davis protocol (the Newington model). A new method of quantifying gait symmetry using the symmetry function (SF) is proposed. SF is an integral measure of absolute differences in time-standardized signals between sides throughout the whole cycle of motion variability.Results: In the frontal plane, there were significant differences between groups in the asymmetry of the range of movement in the hip joint of the intact limb. In the middle of the support phase, the intact limb was more adducted in individuals with MicPK and less abducted in people with MechPK (differences in mean 180%, p < 0.000; max 63%, p < 0.000; min 65%, p < 0.000). In the sagittal plane, the range of asymmetry of the flexion and thigh extension of the intact limb was similar to and only slightly different from the physiological gait. In the transverse plane, higher asymmetry values were noted for individuals with MicPK. In the final stage of the swing phase, the thigh was more rotated both externally and internally. The size of the asymmetry, when compared to gait of healthy individuals, reached 50% (differences in mean 115%, p < 0.232; max 62% p < 0.26; min 50, p < 0.154).Conclusions: In the study group, the assessed ranges of pelvic and thigh movement in the hip joint differed only in the frontal plane. Individuals who underwent a unilateral above-knee amputation may gain less from using MicPK than anticipated.

Background: Ischemic stroke is the most common cause of disability in adults. Deficiency of vitamin D in patients with car-diovascular diseases is increasing. Only a few studies have assessed the relationship between serum vitamin D levels and functional capacity and degree of disability. This study aimed to evaluate the association between serum vitamin D levels and physical outcomes of 94 patients who underwent physical rehabilitation following ischemic stroke. Material/Methods: A group of 94 patients was enrolled; however, 80 patients (61.8 & PLUSMN;6.9 years) were included. They underwent a 6-week rehabilitation using proprioceptive neuromuscular facilitation (PNF, 60 min daily), mirror therapy (MT, 30 min daily), and occupational therapy (OT, 45 min daily). The Barthel Index (BI) and modified Rankin scale (mRS) were used for functional assessments. Laboratory blood tests for serum vitamin D and insulin-like growth factor 1 (IGF-1) levels were conducted. Results: There was a significant increase in BI scores (median difference=2.0 points [pts]; P<0.001) and IGF levels (me-dian difference=124.6 ng/ml; P<0.001) after rehabilitation. There was a significant decrease in mRS scores (me-dian difference=7.0 pts; P<0.001), but there was no significant difference in vitamin D levels (P=0.40). The ef-fect of age (B=-0.01, P=0.04) and serum vitamin D level (B=-0.02, P=0.01) on the BI score was demonstrated. The effect of body mass index (BMI) results (B=-0.07, P=0.02) on the mRS score was observed. Conclusions: Lower serum vitamin D levels and more advanced age may be associated with worse functional outcomes in first-ever ischemic stroke patients.

Stroke is a serious cause of premature death among adults and the reason for much long-term disability. Understanding the mechanisms of disability and the potential for recovery of stroke patients should be one of the highest priorities of the health care system. Neurorehabilitation of post-stroke patients focuses on functional recovery by activating mechanisms of natural reorganization. Proprioceptive neuromuscular facilitation (PNF) and mirror therapy (MT) are neurorehabilitation methods activating brain plasticity, and their clinical utility for stroke survivors is still under studied. This study compared two neurorehabilitation methods using PNF or MT on functional recovery in patients after a first-ever ischemic stroke. This prospective and interventional randomized clinical study involved a group of 50 patients (34 males and 16 females) with first-ever ischemic stroke, aged 48–82 years being in the recovery-compensation stage and admitted to the unit for early post-stroke rehabilitation. Patients were randomly enrolled into two groups in terms of rehabilitation method used: PNF (n = 26) or MT (n = 24). Barthel Index (BI) was used for assessing functional status at baseline (M0), and 3 (M1) and 6 weeks (M2) after intervention), and modified Rankin Scale (mRS) was used for assessing a disability level at baseline (M0), and 6 weeks (M2) after the intervention. Statistically significant differences were noted in the two study groups in BI (main effect: <0.05). There was an improvement in the MT group between M1 and M2 by 3.6 points, M1 and M3 by 6.9 points, and M2 and M3 by 6.9 points. For the PNF group, there were differences between M1 and M2 by 4.1 points, M1 and M3 by 7.2 points, and M2 and M3 by 3.1 points. Moreover, statistically significant differences were noted in both groups in mRS (main effect: p < 0.05). There was a decrease of 2.2 points in the MT group between M1 and M2 measurements. For the PNF group, there were differences between M1 and M2 by 2.3 points. There were no statistically significant differences between the MT and PNF groups in both BI and mRS scores (p < 0.05). In conclusion, both PNF and MT neurorehabilitation methods could be useful for improving functional status and reducing disability level in patients after first-ever stroke during the regenerative-compensatory stage.
