PMA-zeolite supplementation during oxaliplatin chemotherapy significantly reduced the incidence and severity of peripheral neuropathy and other side effects in a double-blind RCT.
The role of ozone treatment as integrative medicine. An evidence and gap map.
A comprehensive evidence map of ozone therapy across 94 clinical conditions identified musculoskeletal and wound-healing applications as the best-studied areas, while revealing major research gaps in neurological and metabolic conditions.
The Effects of Massage Guns on Performance and Recovery: A Systematic Review.
Massage guns improve short-term flexibility and reduce perceived muscle soreness, but evidence for enhancing athletic performance or accelerating strength recovery remains limited.
Clinical Efficacy of Mechanical Traction as Physical Therapy for Lumbar Disc Herniation: A Meta-Analysis.
Mechanical traction significantly reduces pain (VAS) and disability (ODI) scores and improves overall treatment effectiveness in patients with lumbar disc herniation compared to non-traction controls.
Alexander Technique classes improve pain and performance factors in tertiary music students.
Alexander Technique classes reduced pain and improved performance-related factors such as posture awareness and stage confidence in music students.
Systematic review and meta-analyses on the effects of whole-body vibration on bone health.
Whole-body vibration training produces small but significant improvements in lumbar spine bone mineral density, particularly in postmenopausal women.
Effects of rebound exercises on balance and mobility of people with neurological disorders: A systematic review.
Rebound exercise on mini-trampolines improves balance, postural stability, and functional mobility in people with neurological conditions including stroke, multiple sclerosis, and Parkinsons disease.
Autogenic Training in Mental Disorders: What Can We Expect?
Autogenic training shows promise as an adjunctive therapy for anxiety, depression, insomnia, and somatoform disorders, though high-quality evidence remains limited for most psychiatric conditions.
The effectiveness of a 6-month intervention with sit-stand workstation in office workers: Results from the SUFHA cluster randomized controlled trial.
A 6-month cluster RCT found that sit-stand workstations significantly reduced occupational sitting time and improved cardiometabolic markers in office workers.
Clinical Practice Guideline: Nasal Irrigation for Chronic Rhinosinusitis in Adults.
Evidence-based clinical guideline recommends nasal saline irrigation as a core treatment for chronic rhinosinusitis, with large-volume isotonic or hypertonic solutions most effective.
Does whole body vibration therapy assist in reducing fat mass or treating obesity in healthy overweight and obese adults? A systematic review and meta-analyses.
Whole-body vibration reduces body fat percentage and body weight in overweight and obese adults, though effect sizes are modest compared to conventional exercise alone.
Ozone as an adjuvant therapy for COVID-19: A systematic review and meta-analysis.
Ozone therapy as an adjuvant to standard COVID-19 treatment significantly reduced mortality risk and shortened hospital stays, though the overall certainty of evidence was low.
Effects of percussive massage therapy on fascia echo intensity and fascia thickness in firefighters with chronic non-specific low back pain: a randomized controlled trial.
Percussive massage combined with core stability exercises reduced fascia thickness and improved fascia quality in firefighters with chronic low back pain, outperforming exercise alone.
Mini-Trampoline Jumping as an Exercise Intervention in Postmenopausal Women to Improve Women Specific Health Risk Factors.
A 12-week mini-trampoline jumping program improved cardiovascular fitness, lower body strength, and balance in postmenopausal women, supporting rebounding as a practical exercise option for this population.
A four-week minimalist shoe walking intervention influences foot posture and balance in young adults-a randomized controlled trial.
A 4-week minimalist shoe walking intervention improved balance and shifted foot posture toward a more neutral arch in young adults compared to conventional shoe controls.
Biomechanics and Injury Prevention for Barefoot/Minimalist Running.
Barefoot and minimalist running promote a forefoot strike pattern that reduces impact loading rates and may lower injury risk, though a gradual transition period is essential to avoid metatarsal stress injuries.
