Computerized Dynamic Posturography (CDP)
comprised of the Sensory Organization Test (SOT), Motor Control Test (MCT) and Adaptation Test (ADT) protocols is the standard of care for the assessment and treatment of patients with balance, dizziness and mobility problems. Because CDP can identify and quantify the sensory (visual, vestibular and somatosensory) and motor functions involved in balance control, the information obtained provides an efficient means of understanding your patients’ balance deficits and can effectively guide your treatment planning.
Sensory Organization Test (SOT)
The SOT protocol objectively identifies abnormalities in the patient’s use of the three sensory systems that contribute to postural control: somatosensory, visual and vestibular. During the assessment, inaccurate information is delivered to the patient’s eyes, feet and joints through sway referencing of the visual surround and/or the support surface.

Head Shake-Sensory Organization Test (HS-SOT)
The HS-SOT is a two-condition enhancement to the SOT. During the assessment, inaccurate information is delivered to the patient’s feet and joints through sway referencing of the support surface while the patient performs rhythmic head movements about a specified head axis. Separate protocols allow isolation of problems to yaw, pitch, and roll movement axes.
Modified Clinical Test of Sensory Interaction on Balance (mCTSIB)
The mCTSIB is a simplified derivative of the SOT that provides objective evidence of sensory dysfunction, but not specific information related to the individual senses. Postural sway velocity is quantified under four sensory conditions: eyes open firm surface; eyes closed firm surface; eyes open unstable surface; and eyes closed unstable surface.
Stability Evaluation Test (SET)
The SET assesses functional balance control based on the patient’s postural sway velocity during six testing conditions over a period of 2-5 minutes. Results are presented in graphical form, with COG traces shown for each condition tested, and a composite score that quantifies the COG sway or postural stability in a weighted average of all six conditions.
Motor Control Test (MCT)
The MCT assesses the ability of the automatic motor system to quickly recover following an unexpected external disturbance. Sequences of platform translations of varied sizes in forward and backward directions elicit automatic postural responses. The size of the translation is scaled to the patient’s height to produce sway disturbances of equal size.

Adaptation Test (ADT)
The ADT assesses the patient’s ability to minimize sway when exposed to irregularities and unexpected changes in support surface properties. Sequences of platform rotations in the toes-up or toes-down direction elicit automatic motor responses.

Limits of Stability (LOS)
The LOS quantifies the maximum distance the patient can intentionally displace their COG in the four cardinal directions and the four diagonal directions, and maintain stability at those positions. Measured parameters are reaction time, COG movement velocity, directional control, end point excursion, and maximum excursion.
Rhythmic Weight Shift (RWS)
The RWS quantifies the patient’s ability to rhythmically move their COG from left to right and forward to backward between two targets at three distinct speeds The measured parameters are the on-axis COG velocity and directional control.
Weight Bearing Squat (WBS)
During the WBS, the patient is instructed to maintain equal weight on each leg while standing erect and then squatting in three positions of knee flexion. The percentage of body weight borne by each leg is measured with the patient standing at 0° (erect), 30°, 60°, and 90° of knee flexion.
Dynamic Visual Acuity (DVA)
Test The DVA test measures changes in visual acuity at head velocities associated with the Vestibulo-Ocular Reflex (VOR).
Gaze Stabilization Test (GST)
The GST measures the maximum head velocity the patient can achieve while maintaining accurate vision.
Unilateral Stance (US)
The US quantifies postural sway velocity with the patient standing on either the right or left foot with eyes open and with eyes closed.
The STS quantifies the patient’s ability to rise from a seated to a standing position. Key components of this task include shifting the body COG forward from an initial position over the seat to a location centered over the base of support, followed by extension of the body to an erect stand while maintaining the centered COG position. The measured parameters are weight transfer time, rising index (force exerted to rise), sway velocity during the rising phase, and left/right symmetry of the rising force.
Walk Across (WA)
The WA quantifies characteristics of gait as the patient walks across the length of the force plate. The test characterizes steady state gait by having the patient begin well behind and continuing beyond the force plate. Measured parameters are average step width, average step length, speed and step length symmetry.
Tandem Walk (TW)
The TW quantifies characteristics of gait as the patient walks heel to toe from one end of the force plate to the other. Measured parameters are step width, speed, and endpoint sway velocity.
The SQT quantifies turn performance characteristics as the patient takes two forward steps, quickly turns 180° and returns to the starting point. Measured parameters are the time to execute the turn and the sway velocity during the turn execution.
The SUO quantifies motor control characteristics as the patient steps up onto a curb with one foot, lifting the body through an erect standing position over the curb, swings the other foot over the curb, and then lowers the body to land the swing leg on the force plate. Measured parameters are rising index (force to rise), movement time, and impact index (control of impact force descending onto the swing leg).
Forward Lunge (FL)
The FL quantifies movement characteristics as the patient lunges or steps forward onto one leg, then pushes back with that leg to return to a standing position. Measured parameters are distance, time, impact index (impact force) and force impulse.
NeuroCom systems provide the essential elements for objective documentation of each patient’s initial and interim performance over time, as well as automatic comparison of patients’ data to age-matched normative data. An analysis screen and printed reports provide graphic and numeric documentation of movement time, lifting force, landing impact, movement distance, directional control, and sway velocity during functional assessments.
The Evaluation Note provides a printout summarizing the balance performance attributes that were in the abnormal range during the assessment (as compared to the reference population or normative data).
Daily Training Report
The Daily Training Report provides a daily record of the training exercises performed, including the following elements: treatment time, exercise and training parameters, exercise compliance, and clinician entered notes.
The Progress Report is a graphic summary of the patient’s performance over successive testing dates. This report documents improvement over time and provides supportive data for payment or continuation of rehabilitative services.
