Stabilometry in a sitting position

Clinical use. Stabilometry in a sitting position with or without sequential tests of head-neck (P.seq.CC), is used for the investigation of vertigo likely to be of cervical origin by researching the positions of the head in space that trigger the symptomatology. It is also used for the study of the balance of the trunk in a sitting position in those patients who present deficits from pathologies of the central or peripheral nervous system (strokes, ataxias, polyneuropathies, ALS, multiple sclerosis, etc.)

Protocol. The patient is placed barefoot in a sitting position on the platform, following the standard instructions for positioning the feet. It must remain still with the upper limbs with the hands above the knees, while the tibiae are at 90 ° with respect to the femurs which are spread at 30 °. He must remain silent and not move for 30 seconds (standard) to OA and then 30 seconds to OC. If the sequential tests of head-neck are carried out (P.seq.CC) the patient must remain standing for the static tests with the head for 5 seconds in each of the following positions:

• Head in neutral position

• Retroflex head

• Head rotated to the right and left

• Head rotated to the right and left with hyperextension

• Head tilted to the right and left

For dynamic tests, the patient is invited for 5 seconds for each maneuver to do in sequence:

• Continuous rotation of the right / left head

• Continuous head flexion / extension

• Continuous right / left head inclination.

For Postural Stabilometry at 51.2 seconds the patient should be positioned at OA and OC as per standard stabilometry.

Procedures. The indicator used is unique for sequential head-of-neck tests:

1. Stabilogram: search for instability spikes


The standard and postural are used:



3. Subtended area

4. Length of the track


Also here are used normality tables as from literature.

Execution times for the exam: for the standard 1 minute; for the Seq.CC tests 2 minutes. For the Postural 52.1 seconds.

Conclusions. Within 30 minutes the operator analyzes the data (the indicators), prints the graphs and goes to the end, handing it over to the patient in a sealed envelope.

The report written and signed by the doctor with the diagnostic conclusions, the prescriptions or therapeutic recommendations or in-depth clinical studies (MRI, CT etc.) is given to the patient after the examination. If the patient is a physiotherapist / rehabilitation expert, based on the disability, the project and the objective are provided as per PRI (individual rehabilitation plan).

The instrumental exams can then be repeated for the normal follow-up based on the indicators to be checked over time. If, by time control, the same doctor can prescribe the tests to be repeated on the company's request
