STIWELL med4 Surface Stimulator
Training with Functional Electrotherapy
Impulses for your Life
Functional electrotherapy helps you become mobile again after damage to the central nervous system (CNS). Training with the STIWELL med4 assists with your rehabilitation and therefore helps you return to everyday life more quickly. It is used to build muscle strength, promote circulation, regenerate and relax musculature, fight pain and relearn movement patterns.
You can also train at home with the STIWELL med4 after brief therapeutic instruction.
The electrodes are applied to the skin where the musculature is to be activated. Your doctor or therapist establishes the precise electrode position.
Main cable with plug to connect the electrodes
The colours of the electrode cables and plug connectors on the main cable make it easier to assign the four stimulation channels.
With the help of the stimulation device, you can control the stimulation and adjust the intensity of the pulses together with your doctor or therapist. You can also choose from various training programmes.
Advantages at a glance
Control of movements
You can train simple but also complex movement patterns with the STIWELL med4. This is made possible by the four stimulation channels. For example, you can practise how to open and close the hand, or how to correctly bring food to the mouth while eating. Your ability to control the movements on your own keeps improving.
Motivated by training
Intensive and regular training with the STIWELL med4 improves your ability to control muscles as well as your coordination, endurance and strength. Games are provided with the stimulation device for this purpose, making training easier. The STIWELL med4 can be connected to a PC.
Training with electrical impulses
When the central nervous system (CNS) is damaged, consciously controlling certain muscles is difficult. Some residual function does remain in many cases, however the patient is not able to complete the movement. The STIWELL med4 sends electrical impulses through the skin, activating the movements.
During training, you attempt to tense the muscle. If this is successful – even just to a very minor extent – weak electrical signals are generated on the skin as the result of muscle activity. The STIWELL med4 measures these signals, amplifies them and activates the muscle via the nerve.
The brain learns
Through the use of the STIWELL med4, the brain can learn to control the muscles again. It is possible for undamaged regions of the brain to gradually take over tasks from the damaged area – a tremendous effort by the human body.
Three or four muscle groups usually have to be activated in order to learn complex movement patterns. Functional electrical stimulation (FES) using the STIWELL med4 can accomplish this thanks to four stimulation channels. This allows you to practice grasping objects, setting them down in a specific location and releasing them again.
Biofeedback makes your accomplishments visible
When you try to tense the muscle, the response is sometimes so minor that you do not even perceive it. What is known as biofeedback can make these miniscule reactions visible. This is also known as electromyography (EMG). The resulting muscle responses are visualised on your PC or made audible by sounds. By allowing you to perceive the intensity of the responses, even minor training success becomes apparent for you.
Neuromuscular electrical stimulation (NMES) can be prescribed by a physician in the following cases:
- Prevention and delay of muscular atrophy caused by immobilisation (e.g. cast)
- Strengthening muscles during a rehabilitation phase
- Maintaining and/or improving joint mobility
- Muscle relaxation, decubitus (pressure sore) prevention
- Treatment of aconuresis/strengthening the pelvic floor muscles
- Maintaining the trophicity and muscle mass of peripherally denerved muscle groups in the neuromotoric rehabilitation phase
- Functional rehabilitation of the locomotor system
- Treatment of paresis and movement training after nerve reconstruction
- Transcutaneous electrical nerve stimulation (TENS)
Indications for EMG-triggered (EMG-controlled) muscle stimulation and/or biofeedback training:
- Disorders or injuries of the central nervous system (e.g. spasticity or paresis after a stroke, disorders after head/brain trauma)
- Disorders or injuries of the spinal cord (e.g. incomplete paraplegia)
- Peripheral nerve lesions capable of regeneration
- Neuro-orthopaedic functional disorders
- In sports, neuromuscular electrical stimulation can be used for additional muscle training and for muscle regeneration.
