Foot drop is a common clinical condition, mostly caused by nerve injuries such as common peroneal nerve injury and lumbar spinal nerve root injury. Some paralyzed patients, such as stroke and traumatic brain injury patients, may also develop foot drop. Foot drop is mainly due to nerve injury resulting in weakness of the anterior tibial muscles, the foot can not be raised caused, if you want to exercise walking, the first thing is to strengthen the muscle strength of the anterior tibial muscles. There are two methods, when the tibialis anterior muscle does not contract at all, you can use low frequency, acupuncture and other electrical stimulation methods to promote muscle contraction; when the tibialis anterior muscle has some contraction, the dorsum of the foot can be slightly lifted, you can use biofeedback training as well as muscle training, mainly to do resistance muscle training; when the muscle strength of the tibialis anterior muscle is relatively weak, but can do the full range of ankle dorsiflexion, you can do some impedance stronger Only when the tibialis anterior muscle is strong, can we maintain a normal gait in walking.
