The Future of Neck Performance.
Meet the Kinmetrix Arc: the world's first digital neck strengthening device. Enhance power, range of motion, and potentially reduce concussions. Revolutionizing sports safety.
The Numbers Speak for Themselves
Evidence-based performance data driving the Kinmetrix mission.
For every 1-pound increase in neck strength, odds of concussion decreased by 5%*
Concussions go unreported or undetected.
NHL head & neck injuries such as concussion cost $353,300 USD per injury.
A 10% increase in extension strength was associated with a 13% reduction in concussion rate.
The Arc Is Unlike Anything That Came Before
Engineered for Performance
Industrial-strength sensors, robotics, and motors ensure accurate precision and dependability. Built for the demands of elite athletic training.
Precision Sensors
Finally, know exactly where weakness or strength exists and in which movement and isolated area. Easily run performance programs to increase flexibility and directional strength.
360° of Freedom
The neck is a complex system with over 20 different muscles. The Arc allows for measuring and strengthening at all angles — no other device comes close.
Multi-Layer Safety
Multiple overlapping safety features prevent injury during use. Three-point restraints reduce accessory muscle use. No direct forces applied to the head.
Specifications

- Measure Digital Range of Motion (without handheld goniometers)
- Both Iso-Kinetic AND Iso-Metric Exercises
- Strengthen Neck in 360 Degrees
- Resistance levels of up to 300 lbs
- Natural ARC motion isolates specific muscles
Why Neck Strength Matters
Decades of peer-reviewed research support the critical role of cervical strength in athlete safety and long-term health.
Neck Strength & Concussion Risk
For every 1-pound increase in neck strength, the odds of concussion decreased by 5%.
Collins et al., 2014
Extension Strength & Concussion Rate
A 10% increase in extension strength was associated with a 13% reduction in concussion rate.
Mihalik et al., 2011
Neck Strengthening for Headache Relief
Targeted neck strengthening significantly reduces chronic headache frequency and intensity.
Ylinen et al., 2003
Cervical Strength & Posture Correction
Strengthening cervical muscles improves forward head posture and reduces associated pain.
Falla et al., 2007
Neck Strength & Cognitive Health
Cervical muscle strength is positively correlated with cognitive function in aging populations.
Holtermann et al., 2010
Neck Training & Athletic Output
Neck strengthening programs improve reaction time, balance, and overall athletic performance.
Portney & Watkins, 2009
Built for Champions at Every Level
From youth leagues to professional franchises, the Arc delivers the same precision cervical training — protecting every athlete, at every stage of the game.
Professional & Elite Athletes
Hockey, football, rugby, MMA — any contact sport where neck strength is the difference between a concussion and staying in the game.
Sports Medicine Clinics
Offer evidence-based cervical assessment and strengthening programs. Generate detailed exportable reports for patient care and insurance documentation.
Performance Training Facilities
Differentiate your facility with the world's only digital neck strengthening system. Add measurable value to every athlete's training program.
University & College Programs
Protect student-athletes with proactive neck strengthening protocols. Reduce injury liability and improve on-field performance outcomes.
Beyond Sport: The Clinical & Institutional Standard
The Kinmetrix Arc delivers objective, quantifiable cervical data that transforms how clinicians treat, how insurers adjudicate, and how institutions protect the people in their care.
Insurance Providers & Adjusters
Neck injuries are among the costliest claims in sport and motor vehicle accidents. The Arc delivers objective, quantitative cervical data — legally defensible measurements that reduce fraudulent claims, support accurate adjudication, and lower long-term payout risk.
Chiropractors
Differentiate your practice with the only digital cervical strengthening and assessment system. Generate exportable, insurance-ready reports documenting objective ROM and strength data — supporting treatment plans, reimbursement claims, and patient compliance.
Physiotherapists & Sports Medicine
Integrate the Arc into return-to-play and post-concussion rehab protocols. Quantify cervical deficits at intake, track recovery session-by-session, and discharge with documented, peer-reviewed outcomes that give patients and insurers confidence at every stage of care.
Military & Defense
Blast exposure, vehicle rollovers, and load-bearing helmet fatigue place extreme demands on cervical musculature. The Arc provides objective pre- and post-deployment cervical profiling — identifying at-risk personnel, tracking rehabilitation, and building normative data for military populations.
Space Agencies & Aerospace
Microgravity causes significant cervical deconditioning in astronauts, increasing injury risk upon return to Earth. The Arc supports pre-mission strengthening protocols and post-mission rehabilitation — providing the quantitative cervical data that space medicine programs require.
Intelligence Built Into Every Session
