Injuring a tendon might not be immediately noticeable, but it’s crucial to be aware of the potential long-term consequences. Tendon injuries often do not heal properly, which can jeopardize everyday activities and overall functionality.
Understanding Tendon Functionality
Tendons play a vital role in connecting muscles to bones, enabling body movement. When tendon tissue becomes inflamed, ruptures, or deteriorates, it can lead to pain, stiffness, swelling, and weakness. According to Nelly Andarawis-Puri, a bioengineering researcher at Cornell University, even if your muscles are strong, impaired tendons can significantly affect your stability and functionality.
Common Causes of Tendon Injuries
Tendon injuries can occur due to sudden awkward movements, but they are more commonly associated with repetitive activities. For instance, typing for extended periods can lead to hand pain, while repetitive jumping exercises might cause knee problems. Andarawis-Puri notes that the most prevalent type of tendon injury is due to overuse or wear-and-tear, which might not be painful initially and can remain unnoticed for a long time. During this silent period, significant damage can accumulate, leading to degeneration.
Steps to Take if You Suspect a Tendon Injury
If you suspect a tendon problem, it’s essential to seek treatment promptly to prevent further damage. Treatment options may include pain relievers, ice, rest, and sometimes physical therapy. Researchers like Andarawis-Puri are exploring how exercise, under the right conditions, can aid tendon repair. Animal studies suggest that waiting at least two weeks before resuming exercise might be beneficial.
Research and Innovations in Tendon Repair
Animal studies have provided intriguing insights into tendon repair. Some animals, like zebrafish, can regenerate tendon tissue throughout their lives. Jenna Galloway, a regenerative medicine expert at Massachusetts General Hospital and Harvard Medical School, is investigating how mammals respond to fully torn tendons. Unlike zebrafish, human tendons typically scar rather than regenerate.
At the University of Michigan, Adam Abraham is studying how chronic injuries alter tendon fibers. Tendons consist of cells called tenocytes and collagen protein bundles that form long, spiraling chains. These chains function like springs, allowing tendons to absorb force from body movements. Abraham’s team has developed a method to grow 3D structures from patients’ tendon cells, enabling researchers to expose the tissue to various conditions and observe their responses. This research aims to identify potential solutions for tendon repair.
Preventive Measures for Tendon Health
While researchers continue to explore tendon repair, it’s crucial to take preventive measures to maintain tendon health. The National Institutes of Health recommends warming up before physical activities, engaging in regular exercise, taking breaks during repetitive tasks, and gradually increasing activity levels to prevent overuse injuries.
By understanding the importance of tendons and taking proactive steps to protect them, individuals can reduce the risk of injury and maintain their overall functionality.
