“Stroke rehabilitation is difficult to monitor. By testing the patient, before and after acupuncture treatments, the medical staff can document the treatment outcome with objective data. The individual has given up on recovery when he is convinced to try again by his family. Upon seeing the results his treatment is having on hand control, the patient is encouraged to continue with the treatment and is able to regain most of his control of the left hand. Improvements were also seen in the right hand, but to a lesser extent.”

The results of this treatment are presented/published in the American Public Health Association (APHA) 2017 Annual Meeting & Expo (Nov 4 – Nov 8) Abstract #380447: “Utilizing Fine Motor Control Measurements for Outcome-Based Acupuncture Practice: An Evidence-Based Research Study”

Athletes will not report injuries they feel will remove themselves from active play or admit they are not the best athlete. Untreated injuries result in diminished capabilities and poor team results. Closed head injuries, concussions, and mild traumatic brain injuries (mTBI)are difficult to diagnose due to the absence of apparent injury. The injured athlete often denies he or she is even injured. Cognitive symptoms due to the mTBI injury may not appear for weeks.

“Traumatic brain injury (TBI) is a major cause of death and disability in the United States. From 2006 to 2014, the number of TBI-related emergency department visits, hospitalizations, and deaths increased by 53%.”


Red Oak Instrument’s medical device monitors the fine motor control capabilities of sports team members. This allows trainers, coaches, and medical staff to improve capabilities of the team while screening and treating unreported injuries. By monitoring reaction times and hand coordination, small injuries may be detected prior to becoming serious injuries as shown in the figure on sports management below. These measurements may be used as a screening test which detects and quantifies symptoms of mTBI in less than ten minutes. Identifying and documenting a physical injury, protects an injured patient from re-injury.The technology also monitors recovery and rehabilitation rates, and identifying when a patient has fully returned to normal. ROI’s Fine Motor Control screening solution is a patented, peer reviewed, FDA 510(k) approved, with more patents pending.


In the example shown, a tennis player developed a problem with her left hand. ROI’s tests presented the problem, and the trainer addressed the situation. Note that the traditional physical measurement of the reaction times does not indicate a problem at all.

Business Model

Revenue Model

Initial sales or leasing of the equipment will account for initial revenue. This is approximately $5,000 per device/year.

A monthly service fee is included in this amount to provide remote HIPAA compliant access, maintenance, and software upgrades.

As the company grows, we plan to provide remote testing clinics which will provide tests for walk in patients. Our beta testing has been seeing walk in subjects willing to pay $79 to $129 per test. This has been advertised to encourage parents to have their kids tested when they suspect injury. This has shown to be effective with soccer leagues and community sports leagues. Kiosk locations in Malls and/or pharmacy or grocery stores could also be used.

A second-generation sensor system with additional capabilities is already under development and is intended to enhance the capabilities of medical professionals, allowing them to gather more in-depth data. This will give the medical practitioners the ability to better diagnose injuries ranging from traumatic brain injury to Alzheimer’s, and will be available for ~$20,000/yr.

Customer Values

Sports trainers, coaches, physical therapists, sports clinics, wellness clinics, and doctor’s offices can conduct and evaluate the tests, and then charge a fee through a capitated service. Three CPT codes have been successfully used for reimbursements in our beta trials with a minimum reimbursement of $63 per test.

Business Model



Our initial customers are sports teams, schools, and small medical clinics (PTs, chiropractors and acupuncturists); we intend to expand to larger clinics and hospitals within 12 months. We plan to have sales of the units, and the monthly service fees for server access and updates, making Red Oak Instruments cash positive with 3% penetration of the Houston market. We presently have beta units in Montana and Virginia as well as the units in our hometown of Houston.

Competitive Landscape

Most of the competitive testing presently available is subjective and requires a trained medical practitioner to accurately administer the test. This is not how it is done in practice since medical staff are expensive. Red Oak Instrument’s tests are fast, objective, and may be administered by anyone after a one-hour training program.

Our tests are repeatable - if the same person runs a second test, you get the same results.

Our tests are reproducible, different people testing the same person get the same results. Our only competitor who can claim this would be a PET scan (positron emission tomography) and they are expensive.

Competitive Landscape



Beginning in 2008, Red Oak Instruments’ beta units have been tested and used by orthopedic surgeons (CTS), psychologists (PTSD/mTBI), and epidemiologists (mTBI, fibromyalgia, Alzheimer’s). Our mTBI technology has been published in peer reviewed papers and presentations have been made at State and National brain injury conferences.

To further market acceptance, early adopters are encouraged to publish their results in papers on mTBI in appropriate sports/training journals. Acceptance in schools (sports applications) are being pursued through the Parent/Teacher organizations, similar to the defibrillator campaign. Parents want assurance their children are safe and well.

In addition, 100 testing systems have been constructed, calibrated and are ready for commercialization.

    Recently published research in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association provides more evidence that detection of TBI could result in mollifying the effects of dementia 20 to 30 years later. ROI will be expanding its research program to study the correlation between loss of fine motor control and dementia, and more importantly, whether loss of fine motor control can be used to detect early signs of dementia. This would benefit geriatric doctors in their annual physical evaluation of their patients. While dementia cannot be reversed at this time, it appears that it can be delayed and the progression reduced if detected early enough.

    ROI’s unique technology has enabled a Houston Chiropractor to collect supportive data and publish a case report demonstrating the efficacy for additional research into a new chiropractic procedure. The case report, “Non-surgical manual spinal neural decompression adjustment of the Y-axis: Can the results be quantified?” has been accepted this week by The Chiropractic Journal Asia Pacific. The purpose of the initial study was to determine whether or not a measurable physiological change would be detectable in his patients due to his procedure.

    ROI’s systems were able to provide the quantitative physiological information needed to allow this study to be completed. This recent work with a chiropractor now adds to the contribution to research our sensors have provided to GPs, Orthopaedic surgeons, sports trainers, coaches, and acupuncturists over the past few years.
