Knee pain is one of the most common symptoms with running and accounts for about half of running-related injuries. If you are a runner who is experiencing knee symptoms or you are a runner who wants to prevent future injuries, there are several ways you can reduce impact or load on the knee joint. One of the most common causes of movement impairment in running is lack of control or strength of the hip extensors, which can ultimately lead to knee pain.
Habitual postures can also lead to muscle imbalances. A person may be sitting at their desk all day slouching forwards, which can lead to tight hip flexors and lengthened/weak glute muscles. Tight hip flexors can lead to a lack of hip extension range of motion, thus driving an issue at the back. Because the body likes to find ways around restrictions, this person might compensate with excessive mobility at the low back joints to make up for that lack of hip mobility. Over time, changes in these tissues structures can ultimately become a source of pain.
