Harnessing musculoskeletal modeling: A leap forward in personalized muscle strength assessment
2024-06-27
(Press-News.org)
Researchers have developed an innovative method for assessing spinal muscle strength, utilizing isokinetic testing combined with advanced spine musculoskeletal modeling. This cutting-edge approach, detailed in a study published by the Cyborg and Bionic Systems journal, marks a significant advancement in personalized health and athletic training.
Understanding individual muscle strength is crucial for optimizing physical therapy and enhancing athletic performance. Traditional methods, however, often fall short in precision. The newly introduced technique by Zuming Xiao and colleagues from the Beijing Institute of Technology and Shenyang Sport University bridges this gap by integrating direct muscle strength measurements with dynamic simulations.
The study involved five healthy male volunteers, each undergoing detailed isokinetic testing—an objective method to measure muscle strength at constant movement speeds. This data was then synergized with a digital model of the spine's musculoskeletal system, meticulously constructed to mirror the human anatomy's complexities.
One of the key innovations of this research is the incorporation of muscle synergy and intra-abdominal pressure (IAP) in the modeling process. Muscle synergy refers to the cooperative activation of muscle groups, enhancing the model’s accuracy in simulating natural movements. IAP, generated by the abdominal muscles during exertion, plays a significant role in spinal stability, an aspect crucial for both athletes and those undergoing rehabilitation.
The results demonstrated that this integrative approach could identify specific spinal flexor and extensor muscle strengths with unprecedented accuracy. The method’s validity was reinforced through simulations that showed high correlation with actual measured values, proving its potential to transform how muscle strength is assessed and rehabilitated.
For athletes, particularly those in sports requiring significant back strength and flexibility, this method allows for tailored training programs that enhance performance while minimizing injury risks. In rehabilitation, it promises more effective recovery strategies, personalized to individual muscular capabilities and recovery progress.
This breakthrough is a step towards more personalized medicine and training regimens, offering benefits across health care and sports, ensuring individuals not only recover faster but also perform better, backed by a deep understanding of their unique muscular makeup.
The paper, "Muscle Strength Identification Based on Isokinetic Testing and Spine Musculoskeletal Modeling" was published in the journal Cyborg and Bionic Systems on May, 24,2024, at DOI: doi.org/10.34133/cbsystems.0113

OAKLAND, Calif., June 27, 2024 – Power outages are on the rise nationwide as climate change brings more frequent wildfires, heat waves, and severe weather events. The Federal Emergency Management Agency (FEMA) and the state of California have both recently established funding to help communities create “resilience hubs” that rely on solar+battery systems to provide emergency power for residents.
A new study in the journal Risk Analysis finds that strategically placing resilience hubs throughout California could generate up to 8 GW of solar energy and lower the state’s carbon emissions by 5 million tons ...

A new study has illuminated the connection between inflammatory bowel disease (IBD) and lipid profile. IBD is a chronic condition that causes inflammation in the intestines. Abnormal lipid factor levels such as cholesterol in IBD patients have been observed in previous studies, but whether this association is causal remained unclear.
This study employed Mendelian randomization (MR) to investigate the potential causal link between lipid profile and IBD. The results revealed no significant ...

Researchers have identified a protein called PFDN6 that may play a role in the development and spread of colorectal cancer (CRC). The study, published in [journal name], found that PFDN6 levels are increased in CRC patients and contribute to tumor growth. By reducing PFDN6 in lab studies, scientists were able to slow cancer cell spread and increase cell death. These findings suggest that PFDN6 could be a target for future CRC treatments.
CRC is the third most common cancer worldwide and has a poor prognosis, especially ...

When operating on the heart, surgeons may find another issue in the patient. Depending on what they see, the surgical team may address on the secondary condition during the same operation.
These are sometimes called concomitant procedures.
However, two studies led by Michigan Medicine find that female patients who undergo heart surgery are less likely to have secondary ailments corrected during a procedure — despite guidelines that indicate they should.
“Across the spectrum of cardiovascular care, from medical management to transcatheter and surgical procedures, there is growing evidence that women ...

LONDON, ON – A team at Lawson Health Research Institute is the first in Canada to perform a transplant using a technique called abdominal normothermic regional perfusion (A-NRP), which could lead to more organs being available for transplant. The technique was used to optimize organs from two donors in April 2024 at London Health Sciences Centre (LHSC), resulting in the successful transplantation of two kidneys and two livers to four patients.
“Organ donation after circulatory death (when the heart stops beating) has historically been less reliable than organ donation after brain death,” explained Dr. Anton Skaro, Associate Scientist ...
