A strain is a type of acute injury that occurs to the muscle or tendon. Similar to sprains, it can vary in severity, from a stretching of the muscle or tendon to a complete tear of the tendon from the muscle. Some of the most common places that strains occur are in the foot, back of the leg (hamstring), or back. [2]
Nerves play an important role in repetitive strain injuries as it is nerves that get pulled in injured soft tissues ultimately affecting motor functions. [2] Pressure on the nerve will impair blood flow which can impair either distal or proximal points to the first injury and cause pain. [8]
A strain is an acute or chronic soft tissue injury that occurs to a muscle, tendon, or both. The equivalent injury to a ligament is a sprain . [ 1 ] Generally, the muscle or tendon overstretches and partially tears, under more physical stress than it can withstand, often from a sudden increase in duration, intensity, or frequency of an activity.
For example, in the U.S. there were more than 16 million strains and sprains treated in 2004, and the total cost for treating MSDs is estimated to be more than $125 billion per year. [30] In 2006 approximately 14.3% of the Canadian population was living with a disability, with nearly half due to MSDs. [ 31 ]
Sprains can occur at any joint but most commonly occur in the ankle, knee, or wrist. [12] The majority of sprains are mild, causing minor swelling and bruising that can be resolved with conservative treatment, typically summarized as RICE: rest, ice, compression, elevation. However, severe sprains involve complete tears, ruptures, or fractures ...
A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion.. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movem
Strains and sprains to the back muscles can be caused by improper movements while lifting heavy loads, overuse of a muscle, sudden forceful movements, or direct trauma. [8] Herniated discs are associated with age-related degeneration, trauma such as a fall or car accident, and bending or twisting while lifting heavy weights. [ 9 ]
Inversion Ankle Sprain: landing on an uneven surface sprains the ankle. Swelling, localized pain, difficulty bearing weight, and limping are signs of an inversion ankle sprain. [23] Eversion Ankle Sprain: injury related to the ankle turning outward or rotating externally. A typical symptom of eversion ankle sprain is excruciating pain that ...
