Which of the following injuries is a consequence of microtrauma or repetitive stress?

How are overuse injuries diagnosed?

To diagnose an overuse injury, your child’s doctor will take a medical history and gather information such as how often your child trains and at what level of intensity. During a physical exam, the doctor will move your child’s joint around to pinpoint when and where it feels uncomfortable.

The doctor may order x-rays to determine if your child has a fracture. Because stress fractures and growth plate damage are often not visible on x-rays, they may also order an MRI (magnetic resonance imaging). The more detailed images provided by MRI could help confirm the diagnosis.

How are overuse injuries treated? 

Your child’s treatment will depend on the type of injury. Treatment usually starts with R.I.C.E. (rest, ice, compression, and elevation), and sometimes medication to help control pain and swelling.

Rest is the most important thing an athlete can do for an overuse injury. This means restricting all activities that use the injured area for a period of weeks or months — your child’s doctor will recommend a time frame. Depending on the injury, they may also recommend a splint, cast, or boot to protect the injured area as it heals.

For a severe injury, treatment may include:

  • temporary crutches or a wheelchair
  • physical therapy to stretch and strengthen the injured muscles, ligaments, and tendons
  • surgery if the injury is recurring, your child is in constant pain, or if a muscle, tendon, or ligament is badly torn

Nonsurgical innovations in treating tendon and ligament injuries

Boston Children’s Sports Ultrasound Clinic offers regenerative medicine, a minimally invasive approach to treating sports injuries that stimulates the body’s natural healing processes.

  • Shockwave therapy uses shockwaves to stimulate the release of growth factors into injured tissues. The treatment can relieve pain and promote healing of injured tendons, ligaments, and other soft tissues.
  • Platelet-rich plasma (PRP) injections can also stimulate tissue regrowth and healing. Platelets are cells that occur naturally in the blood and promote healing. PRP injections involve isolating platelets in a sample of a patient’s blood and injecting those platelets into the affected area.

How we care for overuse injuries

As the largest and most experienced pediatric and young adult sports medicine practice in the country, the Sports Medicine Division at Boston Children's combines personalized care with innovative treatment for each athlete we treat.

Our Sports Medicine team consists of sports medicine physicians, orthopedic surgeons, physical therapists, podiatrists, athletic trainers, sports psychologists, dietitians, and many others who collaborate in every aspect of our patients’ care and their recovery.

The Micheli Center for Sports Injury Prevention, part of the Sports Medicine Division, is dedicated to the prevention of sports injuries. Through research and clinical training, we offer practical strategies that help young athletes reduce their risk of injury while enhancing their sports performance. Our rehabilitation and strength training programs help injured athletes return to play stronger and healthier.

Whether injury prevention or recovery is your goal, we have the skills and dedication to help your child remain active in the sports they love.

What is a microtrauma injury?

A microtrauma is an injury resulting from repetitive stress to tissues, and is characterized by an insidious onset of symptoms. From: Physical Therapy of the Shoulder (Fourth Edition), 2004.

Which of the following refers to the relative ability of a tissue to resist a particular load?

Stiffness = the relative ability of a tissue to resist a particular load. Stress = the internal resistance of the tissues to an external load. Strain = deformation of tissue due to a load.

Which of the following is the term used for an injury to the Musculotendinous unit?

Abstract. A strain, by definition, is a stretching or tearing of a musculotendinous unit. The degree of disability associated with this injury is dictated by the location and severity of the injury and the specific needs of the patient. A strain can be arbitrarily classified as first, second, or third degree.

Which property of skeletal muscle allows the tissue to return to normal following deformation?

Contractility allows muscle tissue to pull on its attachment points and shorten with force. Muscle tissue also has the quality of extensibility; it can stretch or extend. Following contraction or extension, a muscle can return to its original length when relaxed due to a quality of muscle tissue called elasticity.
