Lingering concussion symptoms
Dizziness, visual strain and slow reactions can outlast the headache. When your exam finds a balance problem, GyroStim becomes part of care for post-concussion symptoms, paced to what you tolerate.
Rancho Santa Fe only
Dizziness, poor balance and slow reactions make a normal day hard work. GyroStim trains how your brain handles motion, one measured session at a time.
Overview
Maybe the room still tilts when you turn your head. Maybe a busy store wears you out, or your reactions feel a step behind on the field.
These problems often come from how the brain handles motion, vision and body position. GyroStim trains that system in a chair that turns you through controlled rotations while you hit targets.
It is one of the tools our neurological rehabilitation center in Rancho Santa Fe uses after a full exam.

What it is
GyroStim is a computer-controlled chair that rotates you on several axes while you aim a laser pointer at lit targets. The motion challenges the inner-ear balance system and the visual system together, so the brain practices taking in motion and responding with accurate movement.
Your exam sets the starting speed, direction and length of each run.
You sit secured in the chair and hit lit targets as it rotates.
The system records your accuracy, and the next run is adjusted to your response.
The re-check
If your run data and symptoms stop improving, we change the plan or tell you GyroStim is not the right tool.
The vestibular system is the balance organ in your inner ear. After a concussion or other injury, its signals can stop matching what your eyes see, a common cause of dizziness.
Conditions
We use GyroStim when your exam shows a balance, motion or visual-motor problem, most often with these conditions.
Dizziness, visual strain and slow reactions can outlast the headache. When your exam finds a balance problem, GyroStim becomes part of care for post-concussion symptoms, paced to what you tolerate.
For people working to regain balance, coordination, and movement after a head injury, often in coordination with their medical providers, GyroStim is one part of rehabilitation after a traumatic brain injury.
Vertigo has several causes, so the exam comes first. Recurring vertigo care can include GyroStim when motion processing is the problem.
GyroStim is one option in a plan for the rocking feeling of MdDS, the swaying that lingers after a boat trip or flight.
GyroStim may help with the balance side of migraine-related dizziness.
When cars, boats or screens bring on nausea, GyroStim can be one part of a gradual plan for motion sickness, starting below your limit.
Why here
True Performance is listed in the official GyroStim provider directory, the only Southern California listing as of September 2026.
Speed, direction and target tasks come from your exam and your last run. Sessions start at or below what your brain handles now, so you are not pushed into a flare.
The chair records accuracy and timing on every run, so you can see whether things are changing.
Other options
GyroStim is not the only way to train balance. Exercises from a vestibular physical therapist help many people. GyroStim adds measured, whole-body rotation, so we use it when your exam shows that extra challenge fits.
Is it for you
If the second list applies, we check with your physician before any session.

A complimentary call about your symptoms and goals.
About 90 minutes, plus data and history gathering. We check balance, eye movement, coordination and motion tolerance.

The clinic
Dr. Jeff McWhorter, D.C., a chiropractor whose practice focuses on functional neurology and concussion rehabilitation, built GyroStim into our concussion and balance program because it gives measured balance training that can be adjusted run by run.
GyroStim is one piece of the brain and balance rehabilitation we provide in Rancho Santa Fe. Book an exam to see whether it fits your goals.
Visit
Rancho Santa Fe only
GyroStim is available at our Rancho Santa Fe office only: 18029 Calle Ambiente, Suite 507, in Cielo Village. We are about two miles from Lake Hodges, with easy access for patients from across North County San Diego.
The first step
We explain cost and payment options on your intro call, before you book an exam. The total depends on how many sessions your plan needs.
You sit secured in the chair while it rotates through set directions and speeds. You aim a laser pointer at lit targets over several short runs, about 30 minutes in all.
Some motion is part of the training, but the chair starts gently, below your current limit. We lower the challenge if symptoms climb.
We work with kids of all ages. With a parent's written consent, the level of GyroStim stimulation is set to the young patient's symptoms and to the results of their first and follow-up evaluations.
Dr. Jeff McWhorter, D.C., sets your GyroStim protocol after a detailed evaluation, exam and review of your injury and history. We re-check as you go and tell you plainly if GyroStim is not helping.
