Knee pain is one of the most common and difficult problems to "explain" in sports medicine clinics and rehabilitation departments. The patient complained of pain when going up and down stairs, sitting for long periods of time, and squatting; Doctors rely on physical examinations, scales, and imaging to make judgments. In the past, when faced with anterior knee pain, clinical and scientific research relied heavily on itscale(Overall Symptoms and Function) andImage(Bone and cartilage structure) to evaluate——Long term lack of rapid, non-invasive, objective, and reproducible quantitative methods for the mechanical state of individual muscles, especially for the presence of mechanical imbalances within muscle groups.A seemingly simple but difficult question to answer isIs there an imbalance within the muscle group? How serious is the imbalance?   Recently,Team ...

Cardiovascular disease is one of the major health burdens worldwide.Biomechanical indicators of arteries, including intramural stress, axial/circumferential stiffness and local blood pressure, are not only the physiological basis for maintaining normal hemodynamics, but also important mechanical clues for the occurrence and progress of hypertension, atherosclerosis, heart failure, stroke and other diseases. These indicators are highly dynamically coupled in time and space and exhibit significant anisotropy,However, existing in vivo measurement methods are mostly limited to a single indicator or rely on multiple measurements at different times/locations and population statistical assumptions, making it difficult to achieve local, synchronous, and individualized mechanical characterization. PART01 New research, new progress New Research & New Developments   In Augus...

  On May 30, 2025, Sun Yang's team from Peking University Third Hospital, together with the team from Beijing Chaoyang Hospital, published a groundbreaking study in the international journal BMC Musculoskeletal DisordersSuccessfully achieved high-precision prediction of PFI (especially patellar tilt and patellar high position), providing a new paradigm for non-invasive dynamic evaluation of PFI.   Article link:https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186/s12891-025-08778-7   Clinical challenge: Lack of dynamic assessment methods for PFI   Knee pain troubles many people,The traditional diagnosis of PFI mainly relies on static imaging examinations such as X-rays, CT, MRI, etc. This often leads to a lack of objective mechanical indicators to guide the development of conservative treatment plans, such as rehabi...

This studymuscle fatigue  BackgroundConcept Fatigue: In daily life, people may experience a decrease in work ability, which is called fatigue. Sports fatigue: In 1982, the American Society of Sports Biochemistry officially defined "the inability of the body to maintain a specific level or intensity of exercise" as sports fatigue. (Decreased work ability - exhaustion) Sports induced muscle fatigue: Sports induced muscle fatigue is defined as a physiological phenomenon in which the maximum voluntary contraction force or output power temporarily decreases when muscles contract due to exercise. mechanism of occurrence ① Exhaustion theory This theory holds that,In motionDuring the process, a large amount of energy substances (ATP, phosphocreatine, sugar, fat, etc.) are consumed in the body, resulting in energy shortage and a decrease in muscle working ability, ...
