PhysioDirect is pleased to announce the introduction of Odstock Functional Electrical Stimulation (FES) technology to their clinical practice. We choose this device because of it’s clinical application and affordability for the user.


The ODFS Pace & ODFS Pace XL are designed to improve walking in people with stroke, multiple sclerosis, traumatic brain injury, cerebral palsy and other neurological conditions.


The Odstockâ Dropped Foot Stimulator (ODFS Pace) is a single channel, foot switch controlled neuromuscular stimulator designed to correct dropped foot in upper motor neuron conditions (where there is damage to the brain and spinal cord (cervical & thoracic segments).   Skin surface electrodes are placed, over the common peroneal nerve as it passes over the head of the fibula and the motor point of tibialis anterior.  Stimulation produces dorsiflexion and eversion of the foot and in certain electrode configurations produces a withdrawal reflex, adding knee and hip flexion. 

The rise and fall of the stimulation can be adjusted to prevent a sudden contraction that might induce a stretch reflex of the calf muscles.  An extension to the stimulation envelope after heel strike can also be added, mimicking the natural activity of the anterior tibialis muscle, which contracts eccentrically to lower the foot to the ground and stabilises the ankle at initial contact.


Dorsiflexion and eversion in swing phase of gait produces:

  • Improved ground clearance
  • Reduced tripping and falls
  • Reduced compensatory activity
  • Reduced effort of walking
  • Reduced spasticity
  • Increased walking speed
  • Heel strike with eversion
  • improved loading response
  • greater stability in stance
  • Greater range of mobility
  • Greater safety, confidence and independence while walking
  • Long term therapeutic benefit
  • Greater social interaction and improved quality of life



The principal application of the ODFS Pace is as a long term mobility aid.  However, the ODFS can also be used in gait re-education following stroke, traumatic brain injury and spinal cord injury.


Walking is facilitated through stimulation of the common peroneal nerve at the knee, activating paralyzed leg muscles and improving motion at the ankle, hip and knee.  A footswitch in the shoe triggers the stimulation as the user walks.


Studies show the ODFS improves walking speed by an average of 27% and walking endurance by 29%, in people who have had a stroke. By preventing the foot from dragging on the ground the Pace also reduces the risk of falling particularly in stroke & MS.


Set up within minutes, the pocket-size ODFS Pace can be worn all day. It provides an immediate, observable improvement in walking even years following the onset of stroke or MS. ODFS users report walking with greater safety, with less effort especially out of doors, with improved confidence in their mobility and with less dependency on a wheelchair.


As an Orthosis, the ODFS Pace & Pace XL are very easy to set up & use on a daily basis.  Users simply: position the electrodes, set up the stimulator, walk & tune the stimulus. At PhysioDirect, our physiotherapists will set this for your unique needs and then show you how to activate for your daily use.


The ODFS Pace uses a wired footswitch. The ODFS Pace XL can use both a wireless and wired options  The ODFS Pace XL, offering a choice of wireless footswitch operation ensures that  triggering of stimulation is best suited to the user’s needs and walking ability. The Pace can be positioned at the knee using a soft velcro band, clipped at the waistline or in a pocket.
