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.
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 (range of motion) of the ankle. Patellofemoral pain syndrome, for example, is often 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.
Foot drop is a condition, that occurs when dorsiflexion is difficult for an individual that is walking. It can severely affect the gait of an individual. It can be caused by nerve damage, muscle or spinal nerve trauma, abnormal anatomy, toxins or disease. Diseases that can cause foot drop include stroke, Amyotrophic lateral sclerosis (ALS or Lou Gehrig's Disease), muscular dystrophy, Charcot Marie Tooth disease, multiple sclerosis, and Friedreich's ataxia. It may also occur as a result of hip replacement surgery.
