About DAVID

Introduction of the DAVID iSeries


DAVID Health Solutions Ltd. is the global leader in evidence-based rehabilitation solutions for musculoskeletal disorders. With the introduction of the i-Series, we’ve redefined how clinics and fitness facilities worldwide deliver intelligent, targeted, and measurable therapy and training—merging state-of-the-art biomechanics with smart automation.

Used by professionals in over 48 countries, the DAVID Exercise Therapy Solution has helped millions of patients overcome chronic and recurrent pain. The i-Series brings this proven approach to the next level, now featuring servo motor-controlled resistance, fully digital loading profiles, and cloud-based data integration.

Each i-Series device is built for joint-specific isolation, biomechanically optimized loading, and pain-free motion, providing a safe and effective training experience. Through our advanced EVE software platform, users receive real-time biofeedback, automated intensity adjustments, pain monitoring, and detailed reporting—beneficial for both clinicians and users.

Originally developed for rehabilitation, the i-Series is now also available for the fitness and wellness industry. This opens the door to preventive, science-based training programs for general members, older adults, and corporate wellness initiatives—bridging the gap between therapy and performance.

Why the i-Series?

  • For clinics: Scalable and standardized care, reduced therapist workload, higher throughput, and better outcomes.
  • For fitness and wellness centers: Evidence-based training, objective progress tracking, joint-friendly resistance, and new service offerings to attract health-conscious members.
  • For members and patients: Safe, motivating, and intelligent training tailored to personal needs—whether recovering, maintaining function, or preventing injury.

In my life, I will never stop developing better ways to help people move without pain.

History of DAVID

DAVID was established in 1981 by Arno Parviainen. The early years involved intensive loading principle development and other biomechanical features. Collaboration was close with Professor Paavo Komi from the University of Jyväskylä. Science papers published several articles validating the variable loading principle integrated into all devices. In the mid-80s, DAVID’s focus started to shift to device-based exercise in rehabilitation. The first product in this area was for knee rehabilitation using sophisticated training and testing technology, including EMG. In the early 90s, DAVID introduced a revolutionary patented hip lock mechanism which allowed therapeutic exercises to be used for even the most severe back patients. The foundation of the David Spine Concept today is the comprehensive treatment program built around the technology. In 1999 Arno sold the company, but in 2008, an opportunity emerged to buy back the business, which Arno did with his son, Lauri, a medical doctor who had an IT company with projects in cloud computing. A series of development projects were initiated, and during the past 14 years, a cloud-based IT platform was introduced in 2010. All products were redesigned, including a completely new shoulder system. Today, DAVID has the world’s most advanced therapeutic exercise platform, but development continues in exciting new areas.

A Word from Our Founder

At DAVID, we’ve always believed that the future of musculoskeletal care lies at the intersection of precise biomechanics, intelligent technology, and human-centered design. With the introduction of the i-Series, we’ve taken a major leap forward—offering our most advanced line of devices yet. These systems combine servo motor technology, adaptive loading, and real-time data integration to deliver personalized, measurable, and scalable training solutions for clinics and wellness centers alike.

While we’re proud of what we’ve built, our journey is far from over. The EVE ECO platform has opened doors to global data collection at a scale never before possible. This growing database will fuel continuous improvement, helping us refine every movement, every protocol, every outcome.

We invite all our users—clinicians, therapists, and members—to share their feedback. Your experiences help us evolve.

In my life, I will never stop developing better ways to help people move without pain.
