Dorsiflexion is the movement which decreases the angle between the dorsum (superior surface) of the foot and the leg, so that the toes are brought closer to the shin. The movement moving in opposite directions is called plantarflexion. The same term can be applied to the wrist and hand, with movement of the palm towards the forearm termed palmarflexion.
Put more simply: it applies to the upward movement of the foot at the ankle joint.
It occurs at the ankle.
The range of motion for dorsiflexion indicated in the literature varies from 12.2 to 18 degrees.
Impact of Limited Range of Motion 
Literature indicates there are several factors that relate to ankle dorsiflexion and that any one of them can cause limitations within the ROM of the ankle. Patellofemoral pain syndrome, for example, is oftentimes associated with tightness in both the gastrocnemius and the soleus. The result of both muscles lacking in flexibility can also cause the ankle to lose range of motion, more specifically, can cause a limitation in dorsiflexion. In turn, this will limit the body's ability to perform weight-bearing tasks when lowering center of mass. This will be most commonly seen during exercises such as the squat, where calf flexibility and ankle range of motion play a significant role.
