This article describes the manufacturing technology of biocompatible flexible strain-sensitive sensor based on Ecoflex silicone and multi-walled carbon nanotubes (MWCNT). The sensor demonstrates resistive behavior. Structural, electrical, and mechanical characteristics are compared. It is shown that laser radiation significantly reduces the resistance of the material. Through laser radiation, electrically conductive networks of MWCNT are formed in a silicone matrix. The developed sensor demonstrates highly sensitive characteristics: gauge factor at 100% elongation −4.9, gauge factor at 90° bending −0.9%/deg, stretchability up to 725%, tensile strength 0.7 MPa, modulus of elasticity at 100% 46 kPa, and the temperature coefficient of resistance in the range of 30–40 °C is −2 × 10⁻³. There is a linear sensor response (with 1 ms response time) with a low hysteresis of ≤3%. An electronic unit for reading and processing sensor signals based on the ATXMEGA8E5-AU microcontroller has been developed. The unit was set to operate the sensor in the range of electrical resistance 5–150 kOhm. The Bluetooth module made it possible to transfer the received data to a personal computer. Currently, in the field of wearable technologies and health monitoring, a vital need is the development of flexible sensors attached to the human body to track various indicators. By integrating the sensor with the joints of the human hand, effective movement sensing has been demonstrated.

Significant evidence suggests that regular physical activity (PA) leads to numerous physical and psychological outcomes in the elderly. This cross-sectional study was designed to further explore this issue by investigating the associations between PA (measured by accelerometer) and kyphosis and lumbar lordosis abnormalities, pain, and quality of life (QoL) in the elderly. In this cross-sectional study, 163 older adults (73 women) over 65 years of age (mean age: 68.70 ± 3.09) from Russia acted as participants. The following instruments were used to measure research variables: ActiGraph wGT3X-BT for measuring PA, spinal-mouse for measuring kyphosis and lumbar lordosis abnormalities, and the World Health Organization Quality of Life Scale (WHOQOL-BREF) questionnaire for measuring QoL. Pain was measured using two questions. The Independent t-test and a regression analysis were used to analyze data. The results showed that our sample participated on average in 15.8 min of moderate PA (MPA) per day, which is lower than the recommended guidelines. Men were significantly more physically active than women. In addition, MPA was significantly associated with lower kyphosis and lumbar lordosis abnormalities and pain in older adults. Finally, MPA was significantly associated with higher QoL. These findings indicate that PA is a critical concern for the elderly. Accordingly, physical educators and fitness instructors should adopt appropriate strategies to promote an active lifestyle among older adults.

The relevance of the research presented in this article is determined by the high prevalence of speech disorders among patients of various profiles. Currently, aphasia accompanies various diseases, which may naturally affect the formation and development of arbitrary regulation among this category of patients, disrupting their processes of self-control in behavioral and emotional reactions. The aim of the article is to identify the features of arbitrary regulation in case of sensory and motor aphasia. The method of studying of the outlined problem is the diagnosis of manifestations of human behavior at the level of arbitrary regulation. For this purpose, the tests "Serial Picture and Story Arrangement" and "Path Tracing" were used. They allow assessing the patient's abilities to concentrate attention, analyze speech text, and exercise emotional and motor self-control. The parameters identified during the study made it possible to distinguish differences in the manifestation of arbitrary regulation at the level of patients with motor and sensory aphasia. In case of sensory aphasia, aspects of low attention concentration and programming activity are observed; a high threshold of emotional excitability alongside with the unstable psycho-emotional sphere can be detected. At the same time, patients with motor aphasia demonstrate the ability to concentrate attention on task performance, stability of psycho-emotional indicators, and high abilities of understanding and analyzing the speech addressed to them. The data obtained during the study will allow specialists to improve the diagnostic, communicative, and neurorehabilitation procedures, thereby enhancing the possibilities for speech restoration in patients with aphasia, which may have practical value for the medical-social sphere.

Acquired speech disorders remain relevant in the scientific literature, given the prevalence and wide range of clinical manifestations. Sensory and efferent motor aphasia differ in various combinations of articulatory and lexical disorders, depending on the temporary organization and localization of lesions. Taking into account the importance of timely neuropsychological assessment for determining correctional and pedagogical tactics, the article discusses the current differential diagnostic aspects of sensory and efferent motor aphasia.
