MUSCLE PHYSIOLOGY

Detailed explanation-1: -Grade 3 muscle strain: The muscle or tendon has completely torn. You might need surgery.

Detailed explanation-2: -Grade III (severe) strains represent the complete rupture of the muscle. This means either the tendon is separated from the muscle belly or the muscle belly is actually torn in 2 parts. Severe swelling and pain and a complete loss of function are characteristic of this type of strain.

Detailed explanation-3: -A muscle tear, also known as a muscle strain or pull, refers to soft tissue damage that has been done to a muscle or its tendons. Injuries to the muscle and tendons can also involve some of the surrounding structures including nerves.

Detailed explanation-4: -Similar to a sprain, a strain may be a simple stretch of your muscle or tendon, or it may involve a partial or complete tear of the muscle and tendon. Symptoms of a strain may include pain, muscle spasm, muscle weakness, swelling, inflammation, and cramping.

Detailed explanation-5: -Overview. A muscle tear or muscle rupture in the hand can impact a person’s ability to perform normal activities of daily living or participate in sports. This type of injury, also called a muscle strain, can result from an acute injury that occurs during sports or normal daily activities or from overuse.
