Foot drop, also known as dropped foot or drop foot, is the inability to raise the front part of the foot up toward the shin. This happens due to weakness or paralysis of the muscles that lift the foot (National Institute of Neurological Disorders). Patients who suffer from foot drop often scuff their toes along the ground; they may also bend their knees to lift their foot higher than usual or swing their leg out to the side to avoid hitting their toes on the ground. Electrical stimulation has been proven to help patients manage symptoms associated with foot drop.
Weakness in the muscles that lift the foot (a movement called dorsiflexion) can be addressed through a comprehensive program using an electrical stimulation device.
The electrical stimulation device works by sending impulses to the muscles via surface electrodes that attach to your skin. This causes the muscles to contract and lift the foot. This movement can help build muscle mass, re-engage the brain, and help stretch the back of the calf, which can sometimes become tight.
A strengthening program with electrical stimulation can be done in a sitting or lying position. While the electrical stimulation unit is flexing your ankle, try to work with it and pull your toes and ankle up further, if possible. Try to aim for 30 minutes per day for this exercise. Both the SaeboStim One and SaeboStim Pro can be used during exercises for foot drop treatment to assist in muscle strengthening.
For those who have some ability to move the ankle, ETS (EMG Triggered Stimulation) can also be used as part of their rehabilitation. An added benefit to this modality is that the user has to actively participate in the movement. With this type of stimulation, the patient lifts the ankle as much as possible. The device detects this movement and when the user reaches a preset threshold, the electrical stimulation is triggered to increase the movement further. The Saebo Myotrac Infiniti is an e-stim device that can be used for this type of triggered stimulation to assist in the treatment of drop foot.
Some people have tightness in their calf muscles at the back of their lower leg. They may struggle to switch off and relax these muscles, which can add to the problem of the already weak muscles at the front of the lower leg. Our Saebo Myotrac Infiniti has a unique program to assist with this issue: Reciprocal EMG Triggered Stimulation or RETS.
During the RETS program, biofeedback is set up on the calf muscles to detect if the muscles are relaxed or tight/over-working. When the user relaxes the calf muscle to a pre-set threshold, stimulation is provided to the muscles that lift the foot, usually the Anterior Tibialis on the front of the shin. This program helps the user learn how to relax the calf muscles before engaging the muscles that lift the foot while walking. This exercise can be also done while sitting as preparation for gait retraining.
The SaeboStim Spa provides circumferential “underwater” nerve stimulation that is consistent, comfortable, and evenly distributed throughout the affected area. This form of stimulation surrounds the feet with a soothing and uniform level of current that treats the underlying conditions.
In addition to providing low-level sensory electrical stimulation for clients suffering from stroke and other neurological injuries, the SaeboStim Spa’s specialized waveforms provide treatment for additional conditions including peripheral neuropathy and nerve pain disorders. This breakthrough device can calm the nerves and increase blood flow which allows the nerve cells the potential to recover.
Many survivors that suffer from foot drop may also experience spasticity, swelling, decreased sensation and/or pain. SaeboStim Spa’s advanced low level stimulation assists in improving many of these symptoms. Simply submerge the affected foot, along with the associated rubber electrodes, into the water for a 30-minute stimulation session daily. This is an excellent way to stay on top of your foot recovery. In addition to regaining more function from your foot, it is equally important to safely improve your gait without risk of falls. The out-of-shoe SaeboStep is a lightweight, uniquely designed foot drop brace that provides convenience and comfort while offering optimum foot clearance and support during walking. The fully adjustable dial tightens the cords to lift up your foot during the swing phase of walking.

There are some medical conditions for which electrical stimulation therapy is not safe to use.
If you have a pacemaker, uncontrolled epilepsy, uncontrolled atrial fibrillation, cancer, or are pregnant, you should not use this type of therapy. When in doubt, contact your physician or a trained therapist for professional advice.
