What Aretech does

Aretech, LLC is a privately held medical device company founded in 2009 by Joe Hidler, PhD and headquartered in Sterling, Virginia. The company designs, engineers, and hand-assembles robotic body-weight support (BWS) systems for rehabilitation therapy, with every system built in-house by the same engineers who developed the original technology. Aretech pioneered the field of robotic body-weight support following a U.S. Military grant aimed at treating wounded service members returning from Afghanistan and Iraq.

The company's product portfolio spans the full rehabilitation continuum: ZeroG and ZeroG 3D provide dynamic gait and balance therapy with TRiP perturbation training for fall prevention; Ovation and Luminaire are dynamic BWS treadmill systems serving higher-weight and space-constrained clinics; and BabyG provides 3D body-weight support for infant and toddler early mobilization. All products are FDA listed, with ZeroG additionally CE MDR marked and IEC 60601-1 certified, and manufacturing operates under ISO 13485 quality management. Notable technical differentiators include dynamic unloading that maintains constant offload through vertical movement (eliminating the 'yo-yo' effect of manual support), patented TRiP perturbation technology for in-motion balance training, DualArrest fall prevention, and the recently launched Arcade 3D interactive gaming suite.

Aretech sells directly to enterprise healthcare customers through an outside field sales team, using custom quotation-based pricing under multi-year contracts. Customers are primarily inpatient rehabilitation hospitals, outpatient therapy clinics, pediatric rehabilitation centers, and VA/military medical facilities serving patients recovering from stroke, traumatic brain injury, spinal cord injury, and other neurological conditions. The company provides its own installation crews and ongoing support, and claims a global customer footprint served from its single Virginia headquarters. No external institutional funding has been disclosed, and the company appears entirely founder-owned.

Core offering

Aretech designs, engineers, and hand-assembles robotic body-weight support (BWS) systems used in clinical rehabilitation to offload patient weight during gait, balance, and fall-prevention therapy. The portfolio includes ZeroG 3D, ZeroG, Ovation, Luminaire, and BabyG systems (plus the Arcade 3D interactive gaming module), which are sold to rehabilitation hospitals, outpatient clinics, pediatric centers, and VA/military medical facilities, with installation and ongoing engineering support provided directly by Aretech.

Product overview

Aretech offers a portfolio of robotic body-weight support (BWS) rehabilitation systems designed for every stage of patient recovery. The core portfolio includes ZeroG 3D (world's #1 selling 3D BWS system), ZeroG (original gait and balance system), Ovation (interactive treadmill training), Luminaire (BWS treadmill), and BabyG (pediatric early mobilization). Add-on modules include Arcade 3D interactive gaming for ZeroG 3D, TRiP perturbation training for fall prevention, and DualArrest fall protection across treadmill systems. All systems are hand-assembled in the USA using precision engineering.

Products and services

• ZeroG 3D The world's #1 selling 3-dimensional body-weight support system that enables patients to move freely in any direction (forward, backward, side-to-side, circular) across a large workspace, supporting complex high-level activities. Designed for inpatient and outpatient rehabilitation facilities delivering intensive gait and balance therapy.
• ZeroG The original robotic body-weight support gait and balance system, pioneered by Aretech since 2009. Provides dynamic BWS with TRiP fall-prevention training, enabling gait therapy, reactive balance recovery, and hands-free fall protection for inpatient rehabilitation programs.
• Ovation Interactive treadmill system with dynamic body-weight support for patients up to 700 lbs. Features DualArrest fall protection, an Infotainment Display, and a wheelchair-accessible Launchpad, enabling high-intensity gait training in clinical rehabilitation settings.
• Luminaire Space-saving dynamic body-weight support treadmill system for patients up to 450 lbs, featuring constant unloading accuracy up to 200 lbs, DualArrest fall prevention, slat-belt treadmill surface, and a 24-inch touchscreen interface. Designed for clinics with limited footprint.
• BabyG Early mobilization system for infants and toddlers providing 3-dimensional body-weight support (2-20 lbs dynamic offload), enabling pediatric patients to develop natural motor skills through self-directed movement and play. Built for pediatric therapy facilities and early-intervention programs.
• Arcade 3D Interactive gaming suite integrated with ZeroG 3D, featuring adaptive games on a 55-inch display that respond to patient movements in real time for postural control, dual-tasking, and high-intensity therapy. Adds an engaging gamified rehabilitation layer to existing ZeroG 3D systems.

Quantifiable outcome

• Patients with acute traumatic brain injury who trained with ZeroG more than doubled functional gains of standard care (59.7 vs 21.1 FIM points, p=0.007)
• +1 more outcomes

Direct peers

• AlterG: AlterG produces anti-gravity treadmills using differential air pressure to provide body-weight support during gait training. It is the most direct non-robotic competitor to Aretech's BWS treadmill systems (Ovation, Luminaire), serving similar outpatient orthopedic and neurological rehabilitation clinics.
• Tyromotion: Tyromotion provides robotic and computer-assisted therapy devices for upper and lower extremity rehabilitation, balance, and gait training. It competes with Aretech in the robotic and sensor-based rehabilitation equipment category sold to neurorehabilitation facilities.
• Motek Medical: Motek Medical (part of DIH) provides advanced gait and balance training systems including the C-Mill and GRAIL, often integrated with body-weight support and virtual reality. It is a direct competitor to Aretech's ZeroG 3D in the instrumented, technology-enabled gait and balance rehabilitation category.
• Ekso Bionics: Ekso Bionics develops robotic exoskeletons for rehabilitation and gait training in stroke, spinal cord injury, and acquired brain injury patients. It competes with Aretech in the robotic-assisted gait rehabilitation category, targeting similar inpatient rehabilitation hospitals and VA/polytrauma centers.
• Hocoma: Hocoma (now part of DIH Medical) is the closest direct peer to Aretech, offering the Lokomat robotic gait therapy system and other robotic rehabilitation devices for neurorehabilitation. Both companies sell robotic body-weight-supported gait and balance therapy systems to inpatient rehabilitation hospitals, making them head-to-head competitors in the same clinical category.
• Bionik Laboratories: Bionik Laboratories offers robotic rehabilitation solutions for upper and lower extremity therapy targeting stroke and neurological recovery. It competes with Aretech in the robotic neurorehabilitation equipment category sold to rehabilitation hospitals and clinics.
• ReWalk Robotics: ReWalk Robotics makes powered exoskeletons for individuals with spinal cord injury and stroke, used in clinical rehabilitation settings. It overlaps with Aretech in robotic-assisted gait therapy for neurological patients in rehab hospitals and VA facilities.

Emerging players

• Woodway: Woodway manufactures specialized medical and rehabilitation treadmills used in clinical gait and sports medicine settings. It is a partial peer via the treadmill platform that Aretech's Ovation and Luminaire systems are built around.
• Restorative Therapies: Restorative Therapies makes functional electrical stimulation (FES) cycling and therapy systems used in neurorehabilitation for patients with stroke, spinal cord injury, and MS. It overlaps with Aretech in serving rehabilitation clinics treating neurological patient populations, though via a different modality.
• Saebo: Saebo produces upper extremity rehabilitation devices and orthoses for stroke and neurological patients, primarily in outpatient and home settings. It is an adjacent player serving similar neurological patient populations but focused on the upper limb rather than gait and balance.
