Factors Affecting Balance Performance in Adolescents.

(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 [ß] = 0.247; 95% CI [0.75, 5.20]; p < 0.01) and better trunk extensor muscle endurance (ß = 0.224; 95% CI [0.015, 0.13]; p < 0.05) were significant predictors of the SLS-EO results, while younger age (ß = -0.219; 95% CI [-1.32, -0.11]; p < 0.05) and higher muscle percentage (ß = 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 (ß = 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.

Student stress and worry related to distance education during the COVID-19 pandemic.

INTRODUCTION: The Coronavirus Disease 2019 (COVID-19) pandemic has caused considerable stress and anxiety in the general population, especially among students. The objective of this study was to determine the stress and anxiety levels among medical rehabilitation students induced by distance education during the COVID-19 pandemic. METHODOLOGY: The sample for this prospective cross-sectional study included 96 students pursuing the medical rehabilitation undergraduate degree at the Faculty of Medicine, University of Novi Sad, Serbia. All respondents took part in an online survey created on the Google Forms platform and accessed via the Facebook social network. The questionnaire included a sociodemographic section, the perceived stress scale (PSS), and the worry about online learning scale (WOLS). All data were analyzed using the IBM SPSS version 25. RESULTS: The study involved 96 students with an average age of 21.97 ± 1.55 years, 72.9% of whom were female. The total stress reported by the students during the COVID-19 pandemic was higher in females than in males (21.75 [SD = 7.50] vs. 17.84 [SD = 8.58]; p < 0.05). Younger students were more susceptible to experiencing stress during the pandemic (rho = -0.217, p < 0.05). Moreover, 57.3% of students suffered from moderate stress, while the WOLS scores indicated that distance education induced a high level of discomfort in this cohort (3.8 [IQR = 1.6]). CONCLUSIONS: Medical rehabilitation students showed a moderate level of stress and a high level of concern about distance education. This stress was more prevalent among younger students and females.

Risk factors for neck pain-induced disability among primary healthcare workers: A pilot study.

BACKGROUND: Neck pain (NP) is associated with high disability rates among healthcare workers. OBJECTIVE: To determine the potential risk factors associated with disability due to NP among healthcare staff working in primary care settings. METHODS: This 30-day prospective cross-sectional study involved a survey of 63 healthcare personnel (55 women and 8 men aged 45.30±12.34 years) of two primary healthcare centers in Serbia, who completed a general questionnaire developed for this purpose along with the Neck Disability Index (NDI), whereby the potential predictors of NP-related disability were assessed using the statistical package SPSS ver. 24. RESULTS: Female healthcare workers achieved a higher score on the NDI scale (Me = 8.00, p < 0.05), as did older respondents (r = 0.260, p < 0.05), those with longer work experience (r = 0.323, p < 0.05), and those that wear prescription glasses (Me = 9.00, p < 0.01). Higher NDI scores were also achieved by respondents that suffered from neck pain at the time of the study (Me = 12.50, p < 0.001), especially if they relied on pain medication (Me = 13.00, p < 0.05), and topical analgesic creams (Me = 12.50, p < 0.05) for treating neck pain. CONCLUSION: Female sex, older age, greater work experience, current neck pain, use of pain-relieving medications and creams, and need for prescription glasses to correct vision increase the risk of disability due to pain in the cervical spine among healthcare workers.

Test-retest reliability of pressure pain threshold and heat pain threshold as test stimuli for evaluation of conditioned pain modulation.

OBJECTIVES: There is growing interest in conditioned pain modulation (CPM) protocols for evaluating the function of the descending pain-modulatory system in clinical settings. The aim of this study was to evaluate test-retest reliability of a CPM protocol with contact heat as a conditioning stimulus (CS) and two test stimuli (pressure pain threshold (PPT) and heat pain threshold (HPT)), all applied within one session. In addition, gender and age differences were evaluated. METHODS: The study included 87 healthy subjects (average age 37.95 ± 12.02 years, 57.5% females). The magnitude of the results of the CPM test was calculated as the difference between subject-reported pain thresholds before and after application of the CS. To assess the reliability of the protocol, a subgroup of 66 subjects underwent re-test after 14±1 days. In order to investigate the influence of age on the CPM magnitude, subjects were divided into subgroups (20-29, 30-39, 40-49, 50-59 years). RESULTS: The pain thresholds for both test stimuli (TS) were significantly higher following the application of the CS (p < 0.001). Values of the interclass correlation coefficient (ICC) for the CPM with PPT as the TS indicated good reliability (ICC=0.631, 95% CI:0.365-0.782), while those for the HPT indicated poor reliability (ICC=0.328, 95% CI:-0.067-0.582). Significant differences in CPM between genders were found for both TS. Significant CPM differences were not detected among the four age subgroups for either TS. CONCLUSIONS: CPM effects can be successfully induced with both PPT and HPT as a TS, but PPT showed significantly higher reliability.

Potential risk factors for back pain in children.

OBJECTIVES: Back pain often develops in early childhood and becomes more frequent during adolescence. The aim of this study was to determine potential risk factors and the therapy effects on back pain in children. METHODS: This retrospective study included 96 boys and girls treated for back pain in outpatient and hospital setting in the 1.1.2016-31.12.2016 period at the Institute of Child and Youth Health Care of Vojvodina, Serbia. The influence of sex, age, physical activity and presence of concomitant locomotor system deformities, as well as applied therapies, on the back pain in children was analyzed using SPSS ver. 21. RESULTS: The studied sample comprised of 56.3% girls. The average age of the subjects was 14.64 years, 43 (44.8%) of the children were physically active. In children suffering from back pain, spinal column deformities were also noted, mostly scoliosis (27.1%) and kyphosis (20.8%). Chronic pain was diagnosed in 54 children (56.3%). The average pain intensity, as measured on the VAS, was 5.72 and 0.92 before and after therapy, respectively (p< 0.05). CONCLUSION: Among the analyzed parameters, only lumboishialgia was a significant factor in the onset of back pain, which declined following ergonomic education and physical therapy.
