Advanced FES Technology

Compared with AFO which mechanically lifts your foot, the FES device provides low-frequency electrical pulses to stimulate the peroneal nerve, which causes the muscle to contract and enables the normally lift the foot. The stimulation can also improve your muscle strength, and flexibility and prevent atrophy. But if your peripheral nerves are damaged, the device may not work to help restore mobility.

User-defined Protocol

You can adjust the specific parameters of the FES machine to get your most comfortable and effective treatment experience and it allows you to save this protocol for the next quick therapy.

Small & Lightweight, Wearable Convenient

Our foot drop stimulator MStim Drop LGT-233 only is small with dimensions of 59(L) × 59(W) × 22(H) mm and weighs only 60g, making it easier to use and giving no burden for patients while walking. The patient can easily wear the device in a cuff below the knee.

Built-in Smart Sensor

The most striking feature of Our MStim Drop LGT-233 is that it has a built-in sensor to detect valid gait events, provide precise stimulation to help clear the foot and measure how far you’ve walked.

APP Control 

Download GZ Longest APP “MStim Drop,” from APP stores, and enable Bluetooth to connect with our FES device to get more intuitive and accurate operation. And you can monitor changes in walking angle every moment and see how far you’ve walked.

Energy Saving & Cost-efficient 

This foot drop stimulator is built with a rechargeable battery that lasts more than 4 hours on a single charge. As there is less need to replace batteries, it’s more cost-saving and more environmentally friendly.

Product Information

Our FES machine MStim Drop provides the foot with dorsiflexion through electrically stimulating muscles in the affected lower leg. It comes with two treatment modes – training mode and walking mode.

  • Training mode is the transition from passive training to walking training for patients who are unable to perform active training. This mode can be selected for muscle training while sitting or lying down, to accelerate muscle recovery, slow atrophy of the injured calf, maintain and improve range of motion in the ankle, and enhance local blood circulation.

  • Walking mode refers to electrical stimulation for foot drop while walking to restore neuromotor function. It can help to maintain a normal gait when walking. Stimulation during walking and repeated training will leave traces on the cerebral cortex. At the same time, it will give feedback to the central nervous system and restore brain neuromotor function.


Our FES device is applicable for patients suffering foot drop caused by:

  • MS, stroke, spinal cord injury, peripheral neuropathy, and other neurological diseases
  • Injury of tibialis anterior

Operation Demonstration


1. What is FES?

Functional Electrical Stimulation, or FES, is a method of externally controlling muscles when signals from the brain can no longer control movement. This can happen after a spinal cord injury, stroke, or neurological disease such as Multiple Sclerosis. FES improves the quality of life for patients with neurological disabilities across the globe. The most common application for FES is the correction of dropped foot. Stimulation is applied to the outside of the leg using self-adhesive electrodes, causing the muscle to contract and the foot to lift; select the image to expand.

2. Why should you choose MStim Drop LGT-233?

Actually, it is a potential market for foot drop. Walking impairment is one of the most common dysfunctions that affect the ability to perform activities of daily living in stroke patients. More than 70% of hemiplegic patients can regain walking ability, but most of them do not achieve good gait and walking speed, which becomes the biggest cause of future falls. Lower extremity motor dysfunction is one of the more serious factors affecting the activities of daily living in stroke patients. Patients with stroke are prone to abnormal gait during walking due to reduced motor muscle strength, poor control, and muscle spasm, increasing the risk of balance disorders and falls.

3. How many treatment sessions could cure the indications?

It varies from the severity of the patient and should be confirmed by the professional therapist.
