This paper presents the development of a robotic system for the rehabilitation and quality of life improvement of children with cerebral palsy (CP). The system consists of four modules and is based on a virtual humanoid robot that is meant to motivate and encourage children in their rehabilitation programs. The efficiency of the developed system was tested on two children with CP. The effect of using the robot is an increase in the number of exercise repetitions, as well as the time spent on therapy, developing and strengthening the child’s musculature. Additionally, the children are able to produce socially acceptable gestures in the context of non-verbal communication for socialization. The main advantages of this system are its flexibility and ease of use. Besides the proposed use in CP rehabilitation, this system can be used in the rehabilitation of people recovering from surgery or injuries. Use of the proposed system significantly decreases the work load of the therapist who would be conducting the repetitive motion, allowing the therapist to see an increased number of patients. In the future, the number of different movements the robot is able to perform will be increased by way of domain-specific modelling and language.

(1) Background: The influence of different factors on balance in adolescence is assessed by conducting functional balance tests that examine its different components. (2) Materials and methods: The study sample comprised 110 healthy adolescents of both sexes, aged 12–18 years. Single Leg Stance with Eyes Open (SLS-EO) and Eyes Closed (SLS-EC) tests were conducted to evaluate static balance, whereas the Functional Reach Test (FRT) and Lateral Reach Test (LRT) were performed to establish functional stability limits. The influence of sex, age, demographic factors, anthropometric characteristics, participation in sports activities, and trunk extensor muscle endurance (Biering–Sorensen test) on balance performance was determined through correlational and univariate linear regression analyses. (3) Results: Older age (Beta [β] = 0.247; 95% CI [0.75, 5.20]; p < 0.01) and better trunk extensor muscle endurance (β = 0.224; 95% CI [0.015, 0.13]; p < 0.05) were significant predictors of the SLS-EO results, while younger age (β = −0.219; 95% CI [−1.32, −0.11]; p < 0.05) and higher muscle percentage (β = 0.237; 95% CI [0.06, 0.48]; p < 0.05) emerged as significant predictors of LRT performance, and greater bone mass was a significant predictor of FRT results (β = 0.444; 95% CI [3.62, 8.17]; p < 0.01). However, none of the independent variables was a statistically significant predictor of the SLS-EC results. (4) Conclusions: The current study found that age, trunk extensor muscle endurance, muscle percentage, and bone mass are significant predictors of different balance components, suggesting that balance is task-specific.

Idiopathic scoliosis (IS) is a three-dimensional deformity of the spine and the trunk, of unknown etiology. Balance or postural control can be defined as the ability to maintain the body's line of gravity above the base of support and thus to avoid falling. Adequate balance control is not only important for maintaining postural stability, but also for safe mobility during activities of daily life. This requires efficient central processing of information coming from the visual, vestibular and somatosensory (proprioceptive) systems. The aim of this article was to review the literature about postural stability and balance performance in patients with idiopathic scoliosis. Some studies showed that people with idiopathic scoliosis have reduced postural stability, assessed with posturography, as well as proprioceptive and vestibular deficits. Two hypotheses in the literature, biomechanical and sensory integration hypotheses, tried to explain this from different points of view. The biomechanical hypothesis emphasizes biomechanical and morphological changes in IS as responsible for poorer postural stability, while the hypothesis of sensory integration points out that certain people with idiopathic scoliosis have impaired dynamic regulation of sensorimotor integration due to an inaccurate evaluation of sensory inputs. Studies that used clinical balance tests showed difficulties in mediolateral stability and dynamic proprioception in IS. Further studies on balance in this population are needed to deepen knowledge in this area.

Background/Objectives: As adults spend about 30% of each day asleep, having a sleep disorder can negatively affect their functioning. The study objective was to determine the factors that influence sleep quality among patients and healthcare providers in the primary healthcare setting. Methods: This study included respondents of both sexes aged 18–90 years, comprising outpatients and the healthcare providers working in the General Medicine Service at the “Liman” Department of the “Novi Sad” Health Center in Novi Sad, Republic of Serbia. Demographic data along with factors related to lifestyle and sleep habits were collected using a demographic questionnaire specifically designed for this research. The standardized Pittsburgh Sleep Quality Questionnaire, Serbian version (PSQI), was used to assess sleep quality. Results: The study sample comprised 92 respondents (42 healthcare providers and 50 patients), 73.9% of whom were female, with an average age of 50.0 years. Although 50% of healthcare providers reported sleeping only 3–6 h the previous night, according to the PSQI results, patients had lower overall sleep quality (54.0% vs. 33.3%; p = 0.046) and achieved lower scores in the DISTB (sleep disturbances, p = 0.001), SLPQUAL (subjective sleep quality, p = 0.013) and MEDS (use of sleeping medication, p = 0.003) PSQI domains. Conclusions: Sleep quality is impaired in more than half of patients and more than a third of healthcare providers. By detecting and acting on the factors in the home and work environment that affect quality of sleep, and by changing lifestyle habits, sleep quality in adults can be improved.

Introduction. Osteoporosis is a metabolic bone disease characterized by reduced bone mineral density and damage to the bone microarchitecture, which leads to bone fragility, thus increasing the risk of osteoporotic fractures. While different diagnostic methods can be employed for detecting bone mineral density decrement in a timely manner, dual energy X-ray absorptiometry remains the gold standard in research and clinical practice. Bone mineral density estimation methods. Osteoporosis can be diagnosed through conventional radiography, quantitative ultrasonography, quantitative computed tomography, and magnetic resonance. Nonetheless, dual energy X-ray absorptiometry is the gold standard in the diagnosis of osteoporosis on which further treatment and monitoring are based. The dual energy X-ray absorptiometry apparatus is equipped with the Fracture Risk Assessment Tool, which estimates the 10- year probability of a major fracture and hip fracture due to osteoporosis. The use and interpretation of osteoporosis diagnostic evaluation modalities is based on the International Society for Clinical Densitometry guidelines for diagnosing osteoporosis in adults and children. According to the International Society for Clinical Densitometry recommendations, the aforementioned quantitative visualization modalities should be used alongside laboratory analyses of bone metabolism markers to supplement diagnostics and monitor treatment efficacy in patients suffering from osteoporosis. Conclusion. Assessment of risk factors and early diagnosis are prerequisites for timely treatment and effective monitoring, which is necessary for arresting the progression of bone mineral density loss and preventing the occurrence of osteoporotic fractures.
