WARNINGS
Neck Stimulation - Stimulation should not be applied over the patient's neck, because severe spasm of the muscles may occur and the contractions may be strong enough to close the airway or cause difficulty in breathing. Stimulation over the neck could also have adverse effects on the patient's heart rhythm or blood pressure. Chest Stimulation - Stimulation should not be applied across the patient's chest because the introduction of electrical current into the chest may cause rhythm disturbances to the patient's heart, which could be lethal. Open or Infected Wounds - Stimulation should not be applied over open wounds or over swollen, infected, or inflamed areas or skin eruptions, e.g. phlebitis, thrombophlebitis, varicose veins. Cancer - Stimulation should not be applied over, or in proximity to, cancerous lesions. Electronic Monitoring Equipment - Stimulation should not be applied in the presence of electronic monitoring equipment, such as cardiac monitors and ECG alarms. Monitoring equipment may not operate properly when the electrical stimulation device is in use. Bathing/Showering - Stimulation should not be applied when the patient is in the bath or shower. Sleeping- Stimulation should not be applied when the patient is sleeping. Machinery Operation- Stimulation should not be applied when the patient is driving, operating machinery, or during any activity in which electrical stimulation can put the patient at risk of injury. ODFS Dropped Foot Stimulator User Manual

Consult with the patient's physician before using this device, because the device may cause lethal rhythm disturbances to the heart in susceptible individuals. Stimulation should only be applied to normal, intact, clean skin. 5.0
PRECAUTIONS
Long-term Effects - The long-term effects of electrical stimulation are unknown. Transcerebral Stimulation - The effects of stimulation of the brain are unknown. Therefore, stimulation should not be applied across the patient's head and electrodes should not be placed on opposite sides of the head.
Gynecology - Caution should be used over the menstruating or pregnant uterus. Sensory Loss - Caution should be used over areas of skin that lack normal sensation. Keep Out of Reach of Children - Keep this device out of the reach of children. Electrodes/Leads - Use this device only with the leads, electrodes, and accessories recommended by the manufacturer. Spasticity - If stimulation causes increased spasticity (involuntary, exaggerated muscle stiffness and spasm), discontinue use and consult your physical therapist.
Pregnancy - The safety of using electrical stimulation during pregnancy has not been established.
Supervision of a Licensed Practitioner - Use this device only under the continued supervision of a licensed practitioner.
Skin Irritation - Some patients may experience skin irritation or hypersensitivity due to electrical stimulation or electrical conductive medium (gel). The irritation can usually be reduced by using an alternate electrode placement. A slight reddening of the skin under the electrode is normal. If stimulation causes long-term marking of the skin, discontinue use and consult your physical therapist.
Latex Allergies- Caution: The Tubigrip elastic stocking contains natural Rubber Latex which may cause allergic reactions. This item is provided as an accessory to the ODFS device. If you are sensitive to products that contain latex, your clinician will discuss possible alternatives (to using this elastic stocking) with you.
Cardiac - Patients with suspected or diagnosed heart disease should follow precautions recommended by their physicians.
6.0
Epilepsy - Patients with suspected or diagnosed epilepsy should follow precautions recommended by their physicians. Hemorrhage - Caution should be used if the patient has a tendency to bleed internally, such as following an injury or fracture. Recent Surgery - Caution should be used following recent surgical procedures when stimulation may disrupt the healing process.

Foot Switch
Stimulating a nerve in the side of your leg will activate the muscles that lift the foot. The stimulation is timed by using a "foot switch" that is worn inside your shoe under the heel of your foot. The ODFS System is made up of several parts connected together and worn on your body. The stimulator allows you to turn the system on and off and to make some adjustments as instructed by your therapist. The stimulator is an electronic device about the size of a pack of playing cards. It may be worn on a belt clip or
in your pocket. The electrode leads are cables worn under your clothing that connect the stimulator to self sticking skin surface electrodes on the side of your leg. A small foot switch is placed in your shoe under the heel. The foot switch is connected to the stimulator by a separate lead. The foot switch turns the stimulation on and off in time with your walking pattern. The cork insole keeps the foot switch in the correct position in your shoe. The elastic tubing helps keep the electrodes and cables in the proper position.

ELECTRODE PLACEMENT
Position yourself comfortably in a straight backed chair. When finding the electrode position and testing the device it is best to have your leg straight. 1. 2.
NOTE: Your therapist may give you different electrode placement instructions to get the best result for you. Follow your therapist's home going instructions including the electrode position worksheet on page 25 of this manual.
Be sure the stimulator is turned off. Connect the electrodes to the leads by inserting the pin on into the connector on the end of the electrode. Push the pin all the way in so no bare metal is seen. Repeat this step for your second electrode. Remove any oil or lotion from your skin before applying electrodes. See section on Preparing the Skin. Check your skin for cuts, abrasions or reddened areas. Do not apply electrodes over these areas. Contact your therapist for instructions. Peel the electrode away from the plastic sheet by lifting at the electrode edge. Do not pull the electrode by the connection. Place the electrode connected to the black plug on your leg as instructed by your therapist. Place the electrode connected to the red plug on your leg as instructed by your therapist. The lead color is important. Typical electrode placement is described below and pictured in Figure 4.

The electrode connected to the black plug is placed over the common peroneal nerve, just below the head (top) of the fibula bone. To find your fibula locate the ankle bone on the outside of the ankle. Run your fingers up this bone on the outside of your leg. The top of the fibula bone will be the bony bump you feel before you get to your knee. The electrode connected to the red plug is placed approximately 2 inches below and slightly forward of the black plug electrode. Common peroneal nerve Top of fibula bone black plug

STIMULATOR SET UP Connect the electrode lead to the socket labelled as OUTPUT on your stimulator. Turn the stimulator on until you hear a beep then press the TEST button. Adjust the level of stimulation by turning clockwise the black dial labelled ON/OFF/ LEVEL to the level recommended by your therapist. Watch your foot move. The ideal movement is the foot lifted (dorsiflexion) with a small amount of turning to the outside (eversion). Your therapist will advise you if your foot movement is correct.
Contact your therapist if you have problems getting the correct response you want from the stimulator.
More Less
NOTE: The test button will provide stimulation for a short period of time and then stop. You will need to press the test button again. a. If the correct movement is not produced: 1. Increase the stimulation level a little 2. Press the test button again b. If the correct movement is not produced adjust the position of the electrodes. 1. If your foot is turning outward too little, bring the active (black plug) electrode further back to increase turning outward. 2. If your foot is turning outward too much, bring the active (black plug) electrode slightly further forward to decrease turning outward. 3. The position of the passive (red plug) electrode can also be adjusted to balance the lift of the foot in the same way. Bring the electrode towards the shin bone to decrease excessive outward turning of the foot. Avoid stimulation directly over the shin bone. It can be uncomfortable.
