Objectives: Determine if (a) a better trunk stability and endurance are associated with an improved whole‐body dynamic balance, and if (b) the assessment tests can be interchanged within each capability.Methods: Sixty‐three physically active young males performed three trunk stability (i.e., the lumbopelvic stability, the unstable sitting and the sudden loading sitting tests), three trunk muscle endurance (i.e., the Biering–Sørensen, the side bridge and the front bridge tests) and four whole‐body dynamic balance (i.e., the tandem and the single‐leg stance, the Y‐Balance, and the single‐leg triple hop tests) tests two times. After assessing the reliability of the variables, a Pearson correlation analysis was performed.Results: The correlations between trunk stability and endurance tests with dynamic balance tests were non‐significant except for the unstable sitting test with both the tandem (r = 0.502) and the single‐leg stance (r = 0.522) tests. Moreover, no relationships were observed between the trunk stability and the trunk muscle endurance tests. Interestingly, no relationships were found between most tests within each capability (i.e., trunk stability, trunk endurance, and dynamic balance) except: (i) the front bridge stability test and the back (r = 0.461) and the side (r = 0.499) bridge stability tests; (ii) the two side bridge endurance tests (r = 0.786); (iii) the tandem and the single‐leg stance tests (0.439 ≤ r ≤ 0.463); (iv) the Y‐Balance and the single‐leg triple hop tests (0.446 ≤ r ≤ 0.477).Conclusion: Better trunk function does not seem to be a relevant factor for dynamic balance in young active males. In this population, specific measures are needed as the test interchangeability is questioned.

People with Alzheimer’s disease (AD) diagnosis who get informal care remain at home longer, reducing the demand for healthcare resources but increasing the stress of caregiving. Research on the effectiveness of physical training, psychoeducational, cognitive–behavioural, and health education programs in reducing the caregiver load and enhancing health-related quality of life (HRQoL) exist, but none exist about an integrated interdisciplinary program. The goals of this project are (1) to assess the Integral-CARE Interdisciplinary Program (IP) applicability, safety, effects on HRQoL, and the incremental cost-effectiveness ratio for AD caregivers; (2) to evaluate the IP applicability and cost-effectiveness to enhance the physical, psychoemotional, cognitive–behavioural dimensions, and the health education status of informal caregivers, and (3) to study the transference of the results to the public and private sectors. A randomized controlled trial will be conducted with an experimental (IP) and a control group (no intervention). The PI will be conducted over nine months using face-to-face sessions (twice a week) and virtual sessions on an online platform (once a week). There will be an initial, interim (every three months), and final assessment. Focus groups with social and health agents will be organized to determine the most important information to convey to the public and private sectors in Extremadura (Spain). Applicability, safety, HRQoL, incremental cost-effectiveness ratio, and HRQoL will be the main outcome measures, while secondary measures will include sociodemographic data; physical, psychoemotional, health education, and cognitive–behavioural domains; program adherence; and patient health status. Data will be examined per procedure and intention to treat. A cost-effectiveness study will also be performed from the viewpoints of private and public healthcare resources.

Background: Maintaining balance is essential for older adults to preserve independence and reduce fall risk. However, empirical evidence linking trunk stability with balance and gait is scarce, partly due to the lack of accessible field tests. Smartphone-based accelerometry field tests offer a promising approach to assess trunk stability outside the laboratory. Objective: The study aimed to determine (1) the association between trunk stability and whole-body balance and gait and (2) the extent to which trunk stability and whole-body balance field tests align with laboratory-based assessments in older adults. Methods: A total of 53 physically active older adults performed 2 trunk stability tests (ie, the lumbopelvic stability [field] and the unstable sitting posturographic [laboratory] tests), 2 whole-body balance tests (ie, the tandem stance posturographic [laboratory] and the whole-body static balance [field] tests), and 2 gait-related tests (ie, the straight-line gait and the modified Timed Up and Go [field] tests) 2 times. A Spearman correlation analysis was performed after assessing the reliability of the variables. Results: Significant positive low-to-high correlations were found between the lumbopelvic stability and the whole-body static balance tests (0.380≤ r ≤0.700; P <.01). A low positive correlation ( r =0.436; P <.01) was also observed between the unstable sitting posturographic test and the tandem stance posturographic test. No correlations were found between trunk stability and any gait-related test. No moderate-to-high relationships (0.289≤ r ≤0.487; P <.05) were found between laboratory and field tests (both for trunk stability and whole-body balance). Conclusions: Better static lumbopelvic control during exercises like the back bridge and the bird-dog is linked to improved whole-body balance in active older adults, suggesting that these positions be included in future interventions to enhance trunk stability. Accessible smartphone-based field tests for lumbopelvic stability offer a promising approach for the standardized assessment of trunk stability. However, direct extrapolation from field tools to laboratory findings is unfeasible due to a lack of correlation. These findings highlight the potential of smartphone-based field tests to complement clinical and research assessments of balance in older adults.

Trunk rotator training is important for performance, stability, and injury prevention, but the intensity of anti-rotation exercises is difficult to quantify precisely. Break-tests may provide a practical method to assess maximal anti-rotation strength and its dependence on body posture. This study determined the intra- and inter-session reliability of a break-test for quantifying maximal anti-rotation trunk strength during a cable woodchop exercise, and examined differences and relationships across common postural configurations. Twenty-two physically active men completed two testing sessions separated by one week. Maximal isometric break force was assessed in seated, kneeling, half-kneeling, staggered-stance, and parallel-stance positions. Force was progressively applied by an evaluator within a standardized time window until posture was lost. Reliability was evaluated using intraclass correlation coefficients (ICC) and typical error (TE), while between-position differences and relationships were analyzed using repeated-measures ANOVA and Pearson’s correlations. The break-test demonstrated excellent intra-session reliability (ICC = 0.90–0.97; TE = 0.4–1.0 kg) and robust inter-session reliability (ICC = 0.78–0.90; TE = 0.8–1.4 kg). Maximal anti-rotation strength was posture-dependent (p < 0.001): half-kneeling produced the highest forces, whereas seated and staggered-stance positions constrained performance. Correlations between positions were moderate to high (r = 0.59–0.84), suggesting shared and position-specific strength characteristics. These findings support the break-test as a reliable and practical method for quantifying maximal anti-rotation trunk strength, helping standardize assessment and guide position-specific load prescription.

Fibromyalgia is a condition that primarily affects women and compromises the quality of life (QoL), life satisfaction (SWL), mental health and cognitive function of sufferers. This study aimed to analyze the effects of a physical activity program based on Virtual Square Step Exercise on the above conditions in women with FM. A 12-week randomized controlled trial was designed with 61 women with FM assigned to a control group (CTL) and an experimental group (VSEE). The VSSE group performed VSSE sessions three times a week for 12 weeks, while the CTL continued with their usual treatment. The applicability and safety of the program was tested in this population. In addition, the participants’ QoL, SWL, mental health status, and cognitive function were assessed before and after the intervention program using different questionnaires and tests. VSEE was found to be applicable (with adherence greater than 85%) and safe (with no accidents, injuries, or health-compromising incidents) in women with FM. The VSEE showed a significant reduction in self-perceived depressive symptoms compared to the control group (p < 0.05). In contrast, no significant changes in QoL, SWL, mental health and cognitive function were observed in the VSEE compared to the CTL (p > 0.05). Therefore, even though our VSEE-based intervention was found to be applicable and safe in women with FM, it did not produce significant changes in improving QoL, SWL, mental health, and cognitive function in our sample. The small sample size and post-pandemic context may have affected the findings. More research with a larger sample size is needed to confirm the effects and applicability of VSEE in women with FM.

Alzheimer’s disease is the most common type of dementia, severely affecting the families and caregivers who live with those affected. The aim was to explore the physical, psychological, and behavioral benefits for caregivers of people with Alzheimer’s disease. Fifteen semi-structured interviews were conducted with informal Alzheimer’s caregivers upon completion of the program. Following a discussion on the topics, categories, and codes among the researchers, a consensus was reached to obtain the final themes and categories. Three main categories were obtained: (1) perceived benefits by the participants; (2) applicability of the knowledge; and (3) proposals for improvement. Participants expressed having perceived improvements in their ability to manage emotions and cope with the situation created by the disease, physical capacity, and in their relationships. In this sense, the application of the contents addressed during the intervention became a fundamental tool for the participants’ daily lives. This study showed how an interdisciplinary intervention with psychological sessions, health education, and physical activities could be beneficial for improving both the physical and mental health of caregivers.
