Motor control principles

Action planning is quickly altered in patients

For many Stroke or CRPS patients, Action planning is altered or non‑existent. They lose awareness of their own body, but also the memory of motor functions.
DESS_OUT_frise_ENG_MotorCtrlPrinciples_V0.7

Without representation of movement, i.e. without this essential stage of action planning, the movement cannot be effective and accurate.

DESS_OUT_frise_ENG_MotorCtrlPrinciples_V0.7
“The problem is not the repetition of movement but the ability to plan what to do.
It’s not a problem of muscle power, it’s a problem of control of the body.”

IVS3 for Upper Limbs

DESS_illus_IVS3_3D

Vision plays an essential role in the early stages of reconstructing body image and motor control. With an intense immersion, IVS allows the patient to reintegrate a healthy functional limb and to focus on the representation of movement.

IVS4 for Lower Limbs

DESS_illus_IVS4_3D
Adapted to wheelchairs, the IVS4 allows patients to work seated to learn basic movements and more complex coordination, then in a standing position, to focus on a functional approach to balance and walking.

“Seeing a movement is almost like doing it.”

IVS replaces the image of the affected limb with a positive image of movement performed by the healthy limb.

Upper or Lower Limb movement observation with IVS automatically induces a cortical sensorimotor activation.

Reinstating coherence between what the patient intends to do and the sensations he perceives prompts relearning.

IVS – Intensive Visual Simulation

Positive visual feedback promotes relearning

IVS relies on brain plasticity principles.

Integrating IVS among the therapeutic pathway stimulates the central control of movement and bolster patients’ abilities in action planning.

The technological platform

Personalized therapy programs

Showcasing more than 15 years of research, IVS integrates a smart therapy-based algorithm assistance to make the therapists’ day-to-day work easier.

Based on the evaluation performed by the therapist, IVS offers a variety of exercise sequences.

It recognizes the best suited movements to the patient’s impairments.

IVS manages the planning of sessions and patient’s overall program.

An “augmented assistant” facilitates the preparation of the session.

Why is IVS
a unique & patented technology?

  1. Intense immersion to reintegrate a healthy functional limb
  2. High level of clinical evidence on VST approaches (both for Upper & Lower Limbs)
  3. Neurological lateralized stimulation
  4. Early start of therapy, accessible to flaccid patients or cognitive disorders
  5. “Enhanced assistant” with diversified exercises
  6. Intensive therapy with few exclusion criteria
  7. Ultra-easy to handle: 30 sec. to start a session
  8. Complementary to conventional approach and robotic devices
