WE ARE THE EXPERTS FOR FUNCTIONAL ELECTRICAL STIMULATION DEVICES

Supplementing lost functions, relearning movement patterns, preserving muscle mass and treating pain are just a few examples to illustrate the possibilities of electrical stimulation. Electrical stimulation has been a valuable tool for rehabilitation for a long time and it is part of MEDELs mission to support caretakers and patients with high-quality electrical stimulation devices for innervated and denervated muscles. In the past years, we put a strong focus on functional electrical stimulation (FES) and developed methods to improve the application of FES with intuitive FES control methods.

Our new Device Generation for Multi-Channel Electrical Stimulation

Multi-Channel Stimulation

  • All of MEDELs devices allow multi-channel stimulation (2-4 channel)
  • Each channel can stimulate a different muscle
  • Each channel can use different stimulation parameters and timing
  • Using multiple channels allows or supports functional movements, e.g. grasping an object
  • Functional multi-channel stimulation enables a muchmore engaging training compared to simple muscle stimulation

KT Motion®: Unique all-in-one-solution

Features

  • Multi-channel functional electrical stimulation
  • EMG triggered stimulation
  • Biofeedback
  • Exponential current to stimulatedenervated muscles
  • Sensor control for dynamic intensitystimulation (DIS)

Benefit

  • EMG triggered multi-channel stimulation can elicit functional movements to support motor learning (e.g. after stroke)
  • Dynamic intensity stimulation assists in performing functional movements and enables task-oriented training
  • Contralateral control of stimulation intensity by using a bend sensor on the healthy hand can be used to intuitively determine the degree of movement of the impaired hand
  • Multi-channel stimulation allows effective muscle strengthening routines (e.g. after spinal cord injury)

 

KT Neuro®: Easy-to-use multi-channel stimulation

Features

  • Multi-channel functional electrical stimulation
  • EMG triggered stimulation
  • Biofeedback

 

Benefit

  • EMG triggered multi-channel stimulation can elicit functional movements to support motor learning (e.g. after stroke)

KT Parese®: Reliable Electrical Stimulation, with a switch

Features

  • Two-channel functional electrical stimulation
  • Easy control with external switch
  • Exponential current to stimulate denervated muscles

  • External switch assist in performing simple functional movements and enables task-oriented training
  • Two-chnalle stimulation allows effective muscle strengthening routines

KT Move®: Simple EMG triggered stimulation

Features

  • Two-channel electrical stimulation
  • EMG triggered stimulation
  • Biofeedback

Benefit

  • EMG triggered stimulation with two channels can elicit simple functional movements to support motor learning (e.g. after stroke)
  • Two-channel stimulation allows effective muscle strengthening routines

Externally controlled stimulation with switches and sensor

Methods

Externally controlled stimulation

Externally controlled stimulation

The timing of the stimulation can be controlled externally through the use of analogue switches and sensors. This makes it possible to trigger and control functional movements and to use the stimulation device for temporary compensation of a motor disability or for task-oriented training, mainly after centrally induced paralyses such as stroke and craniocerebral trauma.The sensor/controller is used to control the pulse width, i.e. the increase and decrease of the stimulation intensity.

EMG-triggered stimulation

EMG-triggered Stimulation

EMG-triggered stimulation programmes are using residual muscle activities, e.g for neurorehabilitation after centrally induced paralysis (e.g. stroke).
A command is generated by the voluntary generation of muscle activity, which triggers a stimulation event.
The electrical muscle activity measured via the surface electrodes is visualised with a bar.
If this exceeds a threshold, the stimulation is triggered.

Biofeedback programmes

Biofeedback programs

Biofeedback programmes are used for the pure display of muscle activity. The electrical muscle activity measured via the surface electrodes is visualised with a bar.

Cyclic stimulation programmes

Cyclic stimulation programmes

Cyclic stimulation programmes are mainly used for strengthening paralysed muscles and for simple movement training after centrally induced paralysis.

Denervation programmes

Denervation programmes

Denervation programmes are used for the stimulation of muscles that cannot be stimulated by classic biphasic square pulses, for example due to a peripheral nerve injury.

Electrical Stimulation and Indications

Stroke

After a stroke many survivors suffer from severe motor impairments. The brain’s ability to learn makes it possible to relearn lost movement patterns. Many repeated movements are necessary during rehabilitation to achieve meaningful results. Functional electrical stimulation can elicit functional movements with controlled current pulses, supporting the patient’s rehabilitation program.

Herniated disc

A herniated disc can cause peripheral paralysis in the leg if the natural stimulus between nerve and muscle is interrupted due to damaged nerves. Electrical muscle stimulation can compensate for a lack of the body’s own impulses: With special triangular impulses via adhesive electrodes on the denervated muscle area. The muscle can contract again without affecting the surrounding innervated musculature.

Craniocerebral trauma

Patients with craniocerebral trauma are often severely impaired in their mobility. Functional electrical stimulation can sustainably support the self-determined practice of everyday movements. The neuroplasticity of the brain makes it possible to relearn movement patterns. By repeatedly performing movements, the non-impaired areas of the brain can take over control of the affected regions.

Incomplete paraplegia

In paraplegia, the connection in the spinal cord is broken. The transmission of commands from the brain to the muscles in the other parts of the body is missing. Body functions that are controlled by the areas of the spinal cord below the respective injury fail. FES helps to maintain or build up muscles, strengthens the cardiovascular system and promotes decubitus prophylaxis.

Injuries

Nerves may have been pinched, pressed or injured as a result of an accident or surgery. If the nerve is very severely damaged, partial or complete peripheral paralysis may result. Functional electrical stimulation has proven to be an effective supplement to occupational and physiotherapeutic services: To prevent muscle breakdown and to build up the muscle cross-section.

Multiple sclerosis

Functional electrical stimulation can enable functional movements and contribute to muscle preservation or restoration. By the application of electrical stimulation pulses spasticity can be reduced and preserving functions of the legs or arms can be supported by the FES assisted movement training.
