STABLE
STability And Balance Learning Environment
Assessment & Training for Fall Prevention
using Therapeutic Virtual Reality Applications
Assess and Improve Stability
and Balance with STABLE
STABLE offers an integrated solution for stability and balance
related disorders. STABLE 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 fun and motivating exercise
games help to train impaired balance control and stability.
Balance (or static postural stability) and dynamic stability are key features
in many therapeutic programs. Many elderly and 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 of elderly, with devastating consequences like
extensive rehabilitation programs or even hospitalization.
STABLE can measure and improve postural stability and balance control.
Assessment applications provide the therapist with objective measures to
define a base level, to monitor treatment progression and to set the level
of personalized training applications. Balance and stability are trained by
immersing patients in a challenging environment with real-time visual
feedback, which is beneficial for fall-prevention. The available exercise
games for training are specifically developed for stability and balance
enhancement in a fun and motivating therapy environment.

STABLE contains a carefully selected set of applications for both the assessment and subsequent training of
balance and stability. Known therapeutic protocols and parameters are implemented in challenging VR
environments.
Assessment
Unambiguous and dedicated assessment applications are used to obtain quantitative and objective outcome
measures, which helps the therapist to identify stability and balance related issues. The applications are used
to define a base-level for your patient and monitor therapy progression.
The STABLE assessment applications include:
Limits of Stability. Measures the maximal Center-of-Pressure (CoP)
displacement in medial-lateral (ML) and anterior-posterior (AP)
directions.
Limits of Stability Envelope. Records various outcome measures, like
maximal distances, movement envelope, speed and deviation from a
straight line, while the patient moves its CoP in 8 different directions.
Postural Stability. Calculates the standard deviation of the CoM while the
patient stands still on two legs, with eyes closed, in tandem stance or in
one-leg-stance.
Visual Tracking. Measures the ability to perform a visual tracking task
using the frequency at which the patient cannot successfully follow a
target.
Functional Reach. This test measures the distance (cm) between arm
length and maximal forward reach, using a fixed base of support.
Speed Knee Bend. Measures how fast your patient performs a knee
bend. The ability to generate muscle forces rapidly like this is very
important for fall prevention.
Dynamic Stability. Calculates response times, needed for
adaptability in daily life which is a prerequisite to prevent falls.
Training
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 STABLE training applications include:
The City Ride. Improves ML and AP stability by maneuvering a CoP driven
car through the city while avoiding approaching traffic.
The Maze. ML and AP stability is challenged when the patient needs to
use its CoP to steer a ball through mazes of increasing difficulty levels.
Reach the Skies. 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.
The Boat. 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.
Road Encounters. In this dual-task application the road visually passes
while stepping on the spot. Objects flying by need to be hit with the
arms.
Hit! Reaction time and muscle force training. Hit the targets as quick as
possible after they appear by making knee bends.
Hit the Mole. Dynamic stability improves while stamping a mole back
underground the moment he shows his head. Watch out, he’ll appear at
different locations.
Traffic Jam. 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.
A STABLE future
Therapeutic concepts and protocols are under constant development
due to cutting edge research, new clinical insights and both patients
and therapists needs. Therefore Motek Medical is continuously
working to improve and develop applications for STABLE. Close
collaborations with leading clinicians and researchers all over the world
ensures a constant high level knowledge for the development of new
applications to improve human performance.

CAREN
CAREN (Computer Assisted Rehabilitation ENvironment) is our leading product.
CAREN is a hardware and software system that creates a virtual environment in
which a patient carries out exercises. CAREN systems always consist of a motion
base, motion-capture system, force-plates, a (semi-cylindrical) projection
screen and the D-flow software. There are three default configurations
available, which can all be tailored to your specific needs.
GRAIL
Your complete gait-lab in 25m2 for gait analysis and gait training using realtime feedback on any gait parameter. GRAIL (Gait Real-time Analysis Interactive
Lab) uses an instrumented dual-belt treadmill, a motion-capture system,
synchronized Virtual Reality environments, 3 video cameras, optional EMG
and a user-friendly off-line analysis tool. GRAIL supports mechanical and visual
challenging conditions to improve (pathological) gait patterns, without being
