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. Strains most commonly occur in the foot, leg, or back.
Sprains are commonly seen in vulnerable areas such as the wrists, knees and ankles. They can occur from movements such as falling on an outstretched hand or a twisting of the ankle or foot. [2] The severity of a sprain can be classified: Grade 1: Only some of the fibers in the ligament are torn, and the injured site is moderately painful and ...
Sprains may be mild (first degree), moderate (second degree), or severe (third degree), with the latter two classes involving some degree of tearing of the ligament. Sprains can occur at any joint but most commonly occur in the ankle, knee, or wrist. [2] An equivalent injury to a muscle or tendon is known as a strain.
Knowing the symptoms that can be experienced with a sprain is important in determining that the injury is not really a break in the bone. When a sprain occurs, hematoma occurs within the tissue that surrounds the joint, causing a bruise. White blood cells responsible for inflammation migrate to the area, and blood flow increases as well. [2]
Miners and poultry workers, for example, must make repeated motions which can cause tendon, muscular, and skeletal injuries. [10] [11] Jobs that involve repeated motion patterns or prolonged posture within a work cycle, or both, may be repetitive. Young athletes are predisposed to RSIs due to an underdeveloped musculoskeletal system. [12]
This causes inflammation, and in turn pain due to the accumulation of histamines, prostaglandins, and potassium. [7] [9] An earlier theory posited that DOMS is connected to the build-up of lactic acid in the blood, which was thought to continue being produced following exercise. This build-up of lactic acid was thought to be a toxic metabolic ...
Stress injuries (stress fractures and stress reactions) of the lumbosacral region are one of the causes of sports-related lower back pain in young individuals. [18] The onset of the observed cervical fractures in sports injury were likely due to continued momentum that transferred loads superiorly through the neck, which exacerbates injuries to ...
Post-thrombotic syndrome (PTS), also called postphlebitic syndrome and venous stress disorder is a medical condition that may occur as a long-term complication of deep vein thrombosis (DVT). Signs and symptoms
