The Odstock® Dropped Foot Stimulator Pace (ODFS® Pace) is a single channel, foot switch controlled neuromuscular stimulator designed to correct dropped foot. Self adhesive skin electrodes are placed on the side of the leg over a nerve called the common peroneal. Stimulation causes the foot to lift (dorsiflexion) and tilt slightly (eversion). Electrode positions can also be chosen that produces a reflex action, adding knee and hip flexion.

For people with dorsiflexor weakness, every step requires high concentration because they tend to scuff their toes along the ground. Even a stone or a small uneven spot can become a big obstacle. Some people may swing the leg forward using their hip muscles. This requires more effort and leads to bad posture, which may result in back pain. Long distances are often avoided as a result of muscle fatigue setting in. This can lead to a withdrawal from social life and activities, and quality of life suffers.
Stimulation feels like pins and needles and most people quickly become used to the sensation.
