The DMO Medical e-step® system combines the benefits of dynamic elastomeric fabric orthosis with neuromuscular stimulation to correct the effects of drop foot.
The effectiveness of the e-step® comes from the complimentary way in which these two parts of the system work together. The DMO Dorsiflex Sock provides stability to the ankle joint at heel strike and throughout the stance phase. The neuromuscular stimulation provides assistance for lifting the foot to produce a more natural walking pattern which avoids the unnecessary and excessive eversion created by some FES systems.
Preliminary studies have shown that use of the e-step® system can reduce the effort required to walk by 50%.
How it works
Small and carefully timed stimulation signals are supplied to the affected leg in time with the steps. This stimulation activates the nerves and then muscles responsible for raising the foot, causing them to contract, lifting the toes clear of the ground as the leg swings forward.
A more natural gait can make walking easier while imposing less stress on joints, something that is particularly important for developing limb function.

The DMO Medical e-step® is a complete drop foot solution that comes supplied with an XFT-2001® neuromuscular stimulator as part of the system. Stimulation is accurately timed to the wearer’s pattern of walking and uses Bluetooth® wireless foot sensor technology or an inbuilt micro-electronic tilt sensor and to detect steps. The system can be set up to use either of these.
The XFT-2001® neuromuscular stimulator used in the e-step® system has a self-tuning function to ensure that whatever footwear is being worn, the stimulator timing will be at optimum setting.
Motion Tilt Sensor
The foot sensor is located in a pocket within the sole of the sock that has a Bluetooth® wireless transmitter which is securely held in an easily accessible pouch. The foot sensor detects when a step is about to commence and communicates with the stimulator to activate the muscles to begin raising the foot. Alternatively the micro-electronic tilt sensor can be used to detect the step by monitoring the position of the leg while walking.
The best method for each wearer will be decided when working with your clinician to set up the system.
