In postural assessment, what is often the cause of excessive bend in the knees?

The excessive bend in the knees during a postural assessment is often attributed to tight hamstrings. When the hamstrings are tight, they can restrict the natural mobility of the pelvis and hips, leading the body to compensate by altering the knee position. When the hips are not able to extend properly due to tightness, the knees may bend more than usual as a way to accommodate for that lack of movement in the hip joint.

Tight hamstrings can create a posterior pelvic tilt, which can affect overall alignment and function, contributing to an altered knee position. This tightness can also limit the range of motion during activities like squatting or running, further reinforcing the compensation of bending the knees excessively.

In contrast, weak quadriceps typically lead to difficulties in extending the knee rather than a bend, shortened calves can affect ankle mobility but do not directly cause knee bending, and weak glutes may lead to other compensatory postures but do not specifically lead to excessive knee flexion. Understanding these connections helps develop more effective strategies for addressing postural imbalances.
