Experience Functional Electro-Therapy

Our vision of electrotherapy places the patient at the centre of pain management and rehabilitation. The treatments we recommend are additional solutions to a range of means within the reach of the person suffering.

Health care providers such as physicians, pharmacists, psychologists, physiotherapists, occupational therapists, and nutritionists work together to relieve pain and improve the patient's well-being.

We offer 4 electrotherapy treatment options

  1. The TENSFor pain management and helps to restore optimal function

  2. The muscle stimulator To improve muscle function

  3. The denervated muscle stimulatorTo artificially maintain the contractile properties of the muscle due to peripheral nerve damage

Pain Management

Transcutaneous Electrical Nerve Stimulation (TENS)

Clinically proven, this method is used in the treatment of many types of pain, both subacute and chronic, by physiotherapists and other health specialists.

How do TENS relieve pain?

TENS electrotherapy enhances the effectiveness of natural pain-control mechanisms. Electrotherapy is a safe treatment: even when used over a long period of time, this method does not present any risk of addiction. Furthermore, this treatment does not cause any undesirable side effects.

The treatment is effective on its own and is also a useful complement to other pharmacological and physical treatments.

In High Frequency

The electrical impulses transmitted by electrodes (placed on the surface of the skin, on or near the painful area) stimulate the sensory nerves, which reduces or closes the passage of pain signals to the brain. The sensation of pain is then temporarily reduced or even imperceptible. This mechanism is explained as part of the Gate Control Theory, as proposed by Melzack and Wall in 1965.

In Low frequency

TENS acts on the release mechanism of endorphins (the body's natural opiates), which foster well-being, quality sleep and pain relief throughout the body.

Muscular Rehabilitation

Neuromuscular Electrical Stimulation (NMES)

The treatment aims to improve the muscle function and quality of one or more normally innervated muscles.

In rehabilitation, the main objectives of home muscle stimulation are:

  • Increased muscle strength following a musculoskeletal injury, in the presence of neurological disorders, before and after surgery
  • Gain or maintenance of joint amplitude
  • Muscle rehabilitation and facilitation
  • Decrease in spasticity
  • Functional electrical stimulation (walking aid)
  • Perineal rehabilitation

In sportsmen and women, muscle stimulation is used to:

  • Improve muscle performance
  • Prepare muscles before a sports activity
  • Relax after the activity
  • Promote a faster return to sport while reducing the risk of relapse after an injury

How do NMES stimulate muscle activity?

Neuromuscular electrical stimulation is applied to a muscle that is normally innervated. Muscle fibres are not directly stimulated, rather it is through their nerve endings that the stimulation is carried out.

Electrodes are applied to the muscle to be worked so that the current stimulates the motor nerve. Depending on the objective of the treatment, one of the electrodes will be positioned directly on its motor point (strongest point of the muscle) in order to obtain a quality contraction.

Treatment of denervated muscles with a muscle stimulator

The treatment aims to artificially induce muscle contractions to keep the muscle healthy (fibrosis prevention). The nerve axons are then allowed to grow back to reach this muscle and restore its ability to contract naturally.

A partial or total denervation of a muscle resulting from:

  • Trauma (surgery, section, tearing)
  • Compression (disc herniation, held position, accident with a heavy object)
  • Viral disease (shingles, facial paralysis, Parsonage-Turner syndrome)

What are the contraindications to using a TENS or a muscle stimulator ?*

Absolute contraindications

  • Circulatory cancer

  • DVT / Active phlebitis / Embolism with low frequency programs

Local contraindications with treatment under medical or interdisciplinary supervision

  • Transthoracic application
  • Anterior face of the cardiac region
  • Genital organs (mandatory training)
  • Electronic implant

  • Pregnancy (abdominal and lumbar region during pregnancy)
  • Epilepsy
  • Sensory skin disorder, loss of sensitivity
  • DVT/phlebitis/embolism (risk of thrombus displacement in the bloodstream)
  • Hemorrhage (may promote bleeding)
  • Tuberculosis (during the active phase)

Local contraindications

  • Transcranial application
  • Anterior region of the neck and carotid sinuses (throat)
  • Eyes
  • All infections
  • Skin damage
  • Persistent undiagnosed pain


  • Circulatory disorder
  • Communication Disorder
  • Skin disease
  • Active epiphyseal plate
  • Preventive anticoagulant therapy (watch for vascular and cardiorespiratory signs and symptoms)

Can I Use the Device During my Daily Activities?

Most patients who use their TENS while performing their daily tasks or during conventional physiotherapy exercises can divert their attention from pain and thus reduce their fears about physical activity (Free translation from the original text: Vaillancourt and Léonard, 2017; Yoshida et al., 2015).

The more you move during your physical rehabilitation, the sooner you recover.

The Functional Electro-Therapy approach developed by Electro Service was specifically designed to encourage patients to remain active during their treatment by following the personalized recommendations of a therapist.
