The aim of this trial is to assess the effectiveness and cost-effectiveness of a supervised and more personalised mhealth intervention compared with conventional exercise therapy in people with chronic non-specific low back pain.

This study aims to evaluate the effectiveness of an Integrated Learning Support System (ILSS) in preparing undergraduate nursing students for immersive simulated training in managing drug-induced nephrotoxicity. The study hypothesizes that the ILSS, which accommodates different learning styles, will be more effective in reducing stress and anxiety compared to the standard learning model (SLM). The research will involve a parallel randomized controlled trial with 96 students from two Brazilian institutions. The students will be divided into control and experimental groups, with the latter using the ILSS in addition to SLM during preparation. The study will assess outcomes such as knowledge acquisition, skill development, and stress reduction using various instruments, including the Lasater Clinical Judgment Rubric and DASS-21. The study's findings aim to validate the ILSS as a tool to enhance learning outcomes and reduce stress and anxiety, thereby promoting better professional development and patient safety in nursing practice.

This study aims to investigate the musculotendinous adaptations in the Achilles tendon and the muscles composing the triceps surae induced by triathlon training and competitions in high-performance and low-performance athletes. Twenty high-performance triathletes, twenty low-performance triathletes, and twenty physically active and healthy individuals of both genders will be recruited to constitute the research groups. Ultrasonography will be employed as the assessment method for the structures of the Achilles tendon and the muscular architecture of the triceps surae. The quality and portability of ultrasonography, coupled with its real-time information capabilities, make it the appropriate choice for this evaluation. The VISA-A scale (Victorian Institute of Sport Achilles Assessment) will be used to measure pain and function of the Achilles tendon. The reliability of ultrasonography measures will be obtained by evaluating images of individuals using the intraclass correlation coefficient, allowing for the analysis of result reproducibility. Data analysis will involve comparisons among the high-performance, low-performance, and physically active groups, aiming to identify differences in musculotendinous adaptations related to performance and injury predisposition. Structural changes occurring in these structures and their potential association with sports performance and/or injury predisposition will be explored. Overall, this study utilizes a comparative cross-sectional research design, where different groups are assessed regarding musculotendinous adaptations in the Achilles tendon and triceps surae through ultrasound-derived measures. The use of the VISA-A scale and the assessment of measure reliability will provide additional data on pain, function, and result reproducibility.
