Digital, Remote, and Ecological Assessment of Fatigue/Fatigability, Mobility, and Functional Activity in Multiple Sclerosis: A Scoping Review
Background/Objectives: Digital, remote, and ecological tools may complement clinic-based assessment in multiple sclerosis (MS), but the distribution of evidence across fatigue/fatigability, mobility, and real-world functional activity remains unclear. This scoping review mapped tools, metrics, constructs, contexts of use, and reported clinical utility in adults with MS, with attention given to whether the evidence was balanced across domains. Methods: Following Joanna Briggs Institute guidance and PRISMA-ScR/PRISMA-S reporting standards, five databases were searched on 14 March 2026. After deduplication, title/abstract screening, full-text assessment, and manual extraction and verification, the findings were synthesized descriptively without formal critical appraisal. Results: Of 3100 records identified, 1433 unique records were screened and 125 sources were included. Gait was the most frequently assessed domain (105/125), followed by fatigue/fatigability (33/125), physical activity (29/125), and sleep (2/125). The most frequent technologies were wearable devices (60/125), accelerometry (54/125), remote/home-based/telemonitoring modalities (52/125), and inertial measurement units (42/125). Conclusions: The evidence is predominantly gait- and mobility-focused, while fatigue/fatigability and broader real-world functional activity are less consistently represented. Reported clinical utility was usually framed around functional assessment, longitudinal/remote monitoring, rehabilitation planning, patient stratification, and decision support, but these characteristics were extracted as reported and were not independently appraised.

Feasibility and Pre–Post Changes Associated with a 12-Week Treadmill Walking Training Programme on Walking Performance, Physical Function, Fatigue, and Quality of Life in People with Multiple Sclerosis: A Single-Arm Pilot Study
Background/Objectives: Walking impairment and fatigue are common in multiple sclerosis (MS) and contribute to reduced physical function and quality of life (QoL). This study evaluated the feasibility, safety, and pre–post changes associated with a 12-week treadmill walking training (TWT) programme on walking performance, physical function, fatigue, and QoL in people with MS. Methods: Single-arm pilot study with pre–post assessments (T1–T2). Eleven adults with MS (Expanded Disability Status Scale [EDSS] ≤ 6) completed supervised TWT for 12 weeks (two 25 min sessions/week) at the Complejo Asistencial Universitario de Soria (Spain). Outcomes included SF-36, Timed Up and Go (TUG), 4 m gait speed, Short Physical Performance Battery (SPPB), and Modified Fatigue Impact Scale (MFIS). Within-participant changes were analysed using paired t-tests or Wilcoxon signed-rank tests as appropriate; effect sizes were reported as appropriate for the statistical test. Results: SF-36 total score did not change significantly (p = 0.160), while general health (p = 0.039) and vitality (p = 0.043) improved. Walking performance improved (TUG, p = 0.007; 4 m gait speed, p < 0.001), and physical function increased (SPPB, p = 0.003). Fatigue impact decreased (MFIS total, p = 0.015; physical, p = 0.007; psychosocial, p = 0.026), whereas the cognitive subscale did not change significantly (p = 0.094). Adherence was 91.7%, and no adverse events were reported. Conclusions: In this pilot sample, a 12-week TWT programme was feasible and safe and was associated with improvements in walking performance, physical function, and fatigue, with QoL changes limited to specific SF-36 domains. These findings support proceeding to a randomised controlled trial to establish efficacy. These findings should be interpreted as preliminary and exploratory, given the single-arm pre–post study design.

Association Between Workplace Sedentary Behavior, Age, and Waist-to-Height Ratio in Spanish Male Workers: An Observational Study in a Large Occupational Cohort
Prolonged sitting (PS) in the workplace has been linked to a higher risk of developing non-communicable chronic diseases. Simultaneously, an elevated waist-to-height ratio (WHtR) is considered a reliable measure of increased risk for the same condition. The main objective of this research was to examine the relationship between workplace PS and increased WHtR among male workers from the Spanish region of Castilla y León. The secondary objective was to assess how age affects elevated WHtR in workers. This retrospective observational study was carried out in accordance with the STROBE guidelines. The sample included 85,670 male workers, categorized by job type (with or without PS) and age (2), Pearson correlation coefficients, and odd ratios (OR) were used to analyze associations. Among workers with PS, X2 = 0.73 (p = 0.391) and 1.11 (p = 0.292) were reported, and among those without PS, X2 = 0.86 (p = 0.354) and 1.24 (p = 0.265), for the years 2022 and 2023, respectively. Therefore, there was no significant association between workers with or without PS and an elevated WHtR, both in those younger than and older than 40 years of age. Advanced age (≥40 years) showed a significant association with increased WHtR (p < 0.01; OR = 2.6). However, no statistical association was observed between PS and elevated WHtR (p > 0.05; OR = 1.15). These findings suggest that age plays a more prominent role than occupational PS time in WHtR among male workers. Future studies should consider other factors, including physical activity and dietary habits, that could affect WHtR.

Effect of Hip Muscle Strengthening Exercises on Pain and Disability in Patients with Non-Specific Low Back Pain—A Systematic Review
Low back pain (LBP) is a health problem that affects 70–80% of the population in Western countries. Because of the biomechanical relationship between the lumbar region and the hip, it is thought that strengthening the muscles of this joint could improve the symptoms of people with LBP. The objective of this study is to evaluate the current evidence on the efficacy of hip strengthening exercises to reduce pain and disability in people with LBP. Clinical trials were collected from the PubMed, PEDro, and Scopus databases published up to September 2022. Based on the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines and using CASP and PEDro tools for methodological quality assessment, we selected studies that included hip strengthening exercises as part of LBP treatment and measured pain and/or disability parameters. Among the 966 records identified in the search, a total of 7 studies met the established selection criteria. Overall, participants who performed hip strengthening exercises had significantly improved in pain and disability. The methodological quality of the included studies was assessed as “good”. In conclusion, the addition of hip muscle strengthening exercises iterating interacted with LBP, effectively improving pain and disability.

Effects on Respiratory Pressures, Spirometry Biomarkers, and Sports Performance after Inspiratory Muscle Training in a Physically Active Population by Powerbreath®: A Systematic Review and Meta-Analysis
Sports performance in athletes can be limited by respiratory factors, so it is understandable to propose that inspiratory muscle training (IMT) can improve respiratory function and exercise performance. Power-Breathe® (PwB) is a sectorized respiratory muscle training tool that uses a resistive load to train IMT. There is currently a growing interest in respiratory muscle training, so we set out to systematically assess the effects of IMT with PwB on respiratory parameters and athletic performance in physically active, healthy adults. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, the Cochrane and PEDro scales to assess methodological quality, effect size using the Rosenthal formula, and the Cochrane tool for estimation of risk of bias, studies searchable in Medline, Web of Science, and Cochrane. In addition, for the performance of the meta-analysis, the documentation and quantification of the heterogeneity in each meta-analysis were directed through the Cochran’s Q test and the I2 statistic; in addition, a publication bias analysis was performed using funnel plots. Of the total of 241 studies identified in the search, 11 studies for the systematic review and nine for the meta-analysis met the exclusion and/or inclusion criteria. IMT, with PwB, showed significant improvements in maximal inspiratory pressure (MIP) and substantial improvements in forced vital capacity (FVC) in the meta-analysis results. Also, sports performance was significantly increased by IMT with PwB. In conclusion, the use of PwB is an IMT tool that improves respiratory and sports performance.

Evaluación de actividad física como coadyuvante terapéutico para pacientes con enfermedad inflamatoria intestinal: una revisión.
Inflammatory bowel disease (IBD) includes Crohn’s disease (CD) and ulcerative colitis (UC). Pharmacological treatment in IBD presents a loss of efficacy and side effects, inviting to consider alternative strategies, such as the practice of physical activity (PA), as a therapeutic adjuvant. The purpose of this review was to evaluate the effectiveness of PA interventions as a tool to in-crease physical fitness, and health-related quality of life (HRQoL) and improve the symptomatology in patients with CD and UC, identifying the optimal PA component. The review was performed, by searching the electronic databases Medline (PubMed), SciELO, and Cochrane Library Plus, including randomized controlled trials from the last 10 years that related to IBD and PA, until January 31, 2022. We found four studies with a total of 133 patients. The performance of PA in patients with IBD (UC and CD) increases (p>0.05) physical capacity, skeletal muscle mass, bone mineral density, and HRQoL, significantly (p<0.05) increasing mood. In addition, it significantly (p0.05) of fatigue, blood pressure, and microbiota restoration was observed. Moderate PA and performed regularly for a minimum of eight weeks, favors the improve-ment of the IBD patient at the physical, psychological, HRQoL, and symptom-atology levels.
