Quadricep and Hamstring Strains
Quadriceps are the muscles in the front of the leg, connecting the hip with the side and front of the knee joint. Hamstrings are the muscles in the back of the thigh that connect the hip to the back of the knee joint. The most common cause for these strains is muscle overload, which is when the muscle is stretched or challenged beyond capacity. There are several risk factors that increase the likelihood of these strains occurring: muscle tightness, imbalance where one muscle is stronger than another, weak muscles, or fatigued muscles. If the strain occurs during an activity, a sudden sharp pain in the front or back of the thigh, depending which muscle group it is, will be felt. Other symptoms include swelling, bruising and weakness that can last for several weeks.
Physical therapy will work to improve range of motion and strength.
