Functional neurology and chiropractic care
Keystone is a small practice for adults with lingering symptoms after a concussion, or with dizziness and balance concerns. We test how your eyes, balance and neck work together, then build a plan with you. It does not cure a disease, and it works alongside your physician.

Scope
Functional neurology is an exam-and-exercise approach to how your eyes, balance and movement work together. It is not a treatment for a disease, and we say so before your first visit.
Your chiropractor looks at how these systems are working today, then plans exercises and care from what the exam shows.
Test eye movements, balance and coordination
Check how your neck and spine move
Write an exercise plan you can follow at home
Recheck on a schedule we set with you
Send a summary to your physician if you ask us to
Some things belong to your physician, and some to the emergency room. We keep to our part.
Act as a treatment for a disease
Replace the physician who diagnosed your concussion
Promise a result or a number of visits
Manage your medicines
Care for sudden or severe symptoms
The assessment
About 75 minutes, in this order.
Your chiropractor asks what you have noticed, what you want back and what your physician has told you. Bring any notes you have.
Simple tests with a penlight, a target and a balance pad. You can stop any test at any point.
We check how your neck and back move and where they are tender.
You leave with your findings in plain words, a short exercise list and a date to recheck. If something needs a physician first, we say so.
Home exercises
Eye-tracking, head-turn and standing-balance drills are short, written down and shown to you in the room. We change them at each recheck and drop what doesn't suit you.
Gaze and eye-tracking drills
Standing balance on firm and soft surfaces
Walking and head-turn practice
A written list you can keep

Questions
Your chiropractor listens first, then tests your eye movements, balance and coordination and checks how your neck and spine move. You leave with your findings in plain words and a written plan. The visit takes about 75 minutes.
Exams and exercises are low risk, and some tests can bring on brief dizziness or tiredness, so you can stop at any point. Hands-on care for the neck carries rare serious risks, which your doctor explains before any adjustment. If you have a sudden severe headache or neck pain, new weakness or numbness, trouble speaking or seeing, call 911 before booking.
Your chiropractor sets a plan after the exam and rechecks it as you go. We don't promise a number of visits or a date for any result, and results vary from person to person.
We bill health plans for visits your plan covers, and plans differ a lot on what they pay. Our care coordinator checks your benefits before your first visit. How fees work explains each step.
You pay at the visit, and your chiropractor tells you the fee for each part of it first. You have the right to a good faith estimate in writing before your first visit. Ask us, and we can give you an itemized receipt to send to your plan.
Call or send a note. Please keep health details for the visit; the form never asks for them.
