C.A.R.E.N Stable Suit with Computer Assisted Rehabilitation Environment (C.A.R.E.N)

C.A.R.E.N (Computer Assisted Rehabilitation Environment) offers an integrated solution for stability and balance related disorders. C.A.R.E.N supports the use of therapeutically constructed Virtual Reality (VR) applications using real-time feedback. Dedicated assessment applications are used for objective and quantitative measurements, while motivating exercise activities help to train impaired balance control and stability. Balance (or static postural stability) and dynamic stability are key features in many therapeutic programs. Many patients with neurological disorders experience difficulties in balance and stability control, potentially restricting a healthy active lifestyle. Impaired balance and stability is often also the cause of falls, with devastating consequences like extensive rehabilitation programs or even hospitalization. C.A.R.E.N can measure and improve postural stability and balance control.

Assessment applications provide doctors and therapist with objective measures to define a base level, to monitor treatment progression and to set the level of personalized training applications. Immersing patients in a challenging environment with real time feedback is beneficial for  balance restoration. The available exercise games for training are specifically developed for stability and balance enhancement in immersive and motivating therapy environment. C.A.R.E.N contains a carefully selected set of applications for both the assessment and subsequent training of balance and stability. Proven, precise therapeutic protocols are implemented in challenging VR (Virtual Reality) environment.


Unambiguous and dedicated assessment applications are used to obtain quantitative and objective outcome measures, which helps the therapists to identify stability and balance related issues. The applications are used to define a base-level of the patient and monitor therapy progression.

The Stable Assessment Aplications Include:

  1. Limit of stability;
  2. Measures the maximal Center-of-Pressure (CoP);
  3. Mediolateral displacement.


Fun, motivating and engaging exercise sessions are supported by a set of training applications with immersive VR environments and game-play. Exercise applications are driven by therapeutically relevant parameters. Training intensities are set automatically by the patient specific assessment application outcomes. However,the therapist is always in control to decrease or increase the intensity of the training.

The C.A.R.E.N balance stability training applications include:

Improves ML( Medio-Lateral) and AP (Anterio-Posterior) stability by maneuvering a CoP(Center of Pressure) driven car through the city while avoiding approaching traffic.

ML and AP stability is challenged when the patient needs to use its CoP to steer a ball through mazes of increasing difficulty levels.

Visual balance is trained in this application where the patient mimics a wobbling tower while blocks that fall from the sky need to be caught to build a higher tower.

Dynamic stability is required to successfully steer a boat through a challenging track without hitting buoys or sharks. The goal is to complete the track as fast as possible.

In this dual-task application the road visually passes while stepping on the spot. Objects flying by need to be hit with the arms.

Reaction time and muscle force training. Hit the targets as quick as possible after they appear by making knee bends.

Dynamic stability improves while stamping a mole back underground the moment he shows his head. Watch out, he’ll appear at different locations.


Don’t cause a traffic jam by alternately re-locating your feet at the right time to let cars pass. Be careful not to stop the police.

In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
