Sports Concussion Assessment Device

Developed by TBI Diagnostics Pty Ltd.

The SCAD Deck Balance Tracking System Assess Balance System gives health professionals an all-in-one solution to assess and train balance by administering computerised protocols with gold-standard force plate technology. SCAD Deck is used for balance assessment, fall risk analysis, balance improvement programs, concussion management,  wellness, chiropractic care, physical therapy, vision therapy and balance research.

Protocols are easy to administer and results include comparisons to normative data where possible. Since being introduced in 2014, over 250,000 tests have been performed.

SCAD Deck has set a new standard for accurate, reliable and affordable balance testing and training.

Balance and Posture are important indicators of health and well-being.

How it Works


The sensitivity of the SCAD Deck Balance Plate and Sport Balance software for concussion was quantified by calculating the percentage of concussed athletes who showed a decline in balance from baseline testing to post-concussion testing.

The criterion for determining whether a decline in balance had occurred was an increase in the BBT result of more than 5 cm (i.e. more than 5 cm greater sway following concussion compared to baseline), as prescribed by the SCAD Deck Sport Balance software.


Balance Testing for Physicians, Hospitals, and Senior Living Facilities has never been easier or more affordable.
Falls represent a potential liability issue in medical facilities including both hospitals and doctor’s offices.

This is the first affordable, objective force-plate testing system allowing hospitals to obtain a computerised balance and fall risk assessment in minutes.  At completed the patient’s fall risk is assessed as Low, Moderate, or High.

Balance Tests

SCAD Deck Assess Balance Software provides protocols for balance assessment and protocols for balance training and rehabilitation. The protocols for assessment include:

Balance and Fall Risk Assessment

The BBT Test is a general balance assessment providing detailed postural sway analysis. After each trial, the centimeters of postural sway are calculated and compared to over 20,000 norms to calculate percentile rankings. In addition, a fall risk assessment of Low, Moderate or High is provided with each test result.

Weight Distribution

Accurately determine weight distribution percentages in the left/right and front/back directions as well as the location of body center of pressure as it relates to global postural alignment.


The Clinical Test of Sensory Integration and Balance is used to assess how the main three sensory feedback systems for balance (i.e. proprioception, vision, vestibular) function relative to one another. Integrated normative data provides percentile rankings for each of the four trials.

Limits of Stability

Measure the functional base of support using this biofeedback assessment. Patients stand with feet flat on the plate and lean as far as possible in all directions. The total area, and the area in each quadrant of the plate is calculated in real time.

Cervical Challenge

Measure postural sway with the patient’s head in 11 different positions. The different positions expose specific vestibular configurations and performance on each trial can be interpreted and utilised by a trained neurologist.

Single Leg Stance

The Single Leg Stance Test compares the postural sway of an individual when they stand on their left foot versus when they stand on their right foot. When completed, the left-versus-right results are compared and a Symmetry Index is calculated. A person is considered within the Symmetric Range if they show less than 15% difference between right and left.

Balance Training & Rehabilitation

SCAD Deck Assess Balance comes with multiple training protocols that allow focused training of postural control. This includes Left/Right, Front/Back, Diagonal and Random Target acquisition protocols, as well as a Target Tracking protocol.

SCAD Deck Balance Training helps individuals learn to control postural sway using biofeedback. During training, the real-time location of a person’s center of pressure, must move their center of pressure into targets of varying difficulty.

Each of the five training programs run for default of three minutes but can be longer or shorter as desired. Left/Right and Front/Back deliver uniaxial targets in various sizes and locations. Diagonal delivers biaxial targets in various sizes and locations.

Reporting and Tracking

One of the most important features of Assess Balance is the tracking and reporting of results. Each time an individual is tested, the results are stored and available to compare against prior results.

A concise and detailed report is always available to share with the individual, their family and their health providers.

These same reports can be used for billing and if needed, for personal injury validation. All the reports are stored locally on the computer and can also be stored in local or cloud based servers.
