The InMotion ARM is an evidence based, intelligent interactive rehabilitation technology that senses patient movements and limitations, providing assistance-as-needed™ in real-time. It allows clinicians to efficiently deliver optimum intensive sensorimotor therapy to the shoulder and elbow to achieve the development of new neural pathways. The InMotion ARM has been sold in over 20 countries, including the United States for rehabilitation. Extensive research has shown it to be effective, especially for stroke and cerebral palsy

Broad clinical application shown to improve functional outcomes across the continuum of care.1


InMotion ARMTM Software

Intensive — 1024 movements per therapy session with evidence-based treatment protocols.

Therapy protocols allowing clinicians to customize treatment. Therapeutic exercise games for:

  • Motor planning
  • Eye-hand coordination
  • Attention, visual field deficits/neglect
  • Massed practice

2D Gravity Compensated Therapy is more effective than 3D Spatial Therapy 

IMT’s modular, “gym-of-robots” systems approach to neurorehabilitation is the only system designed to optimize the use of robotics for neurorehabilitation in a manner that is consistent with the latest clinical research and neuroscience, taking into account the latest understandings on motor learning interference and motor memory consolidation. For instance, training planar and vertical (anti-gravity) movements in alternate days leads to better outcomes than training during the same session2.

By measuring patient kinematic and kinetic data objectively, IMT’s robots have shown that for severe to moderate brain injury the effectiveness of therapy is optimized by allowing the robots to focus on reducing impairment and allowing the therapist to assist on translating the gains in impairment into function.

InMotion EVAL™

Quantifies upper extremity motor control and movement recovery allowing clinicians to distinguish true recovery from compensation

Establishes a baseline and measures progress to:

  • Determine medical necessity
  • Justify continuation of treatment based upon measurable gains

Quantifiable measures for:

  • Shoulder stabilization
  • Smoothness of Arm movement
  • Arms ability to move against resistance
  • Mean and Maximum arm speed
  • Arm Reaching error
  • Joint independence

Correlated with traditional assessment scales:
Fugl-meyer, Motor-Power and NIH stroke scale performance*

Maximum Shoulder Force

Optional InMotion Eval module.

Allows clinicians to measure a patient’s ability to generate maximum shoulder flexion/extension, adduction/abduction force.

Custom Designed Technology

6 degree-of-freedom force-torque sensor monolithic aluminum device containing analog and digital electronics systems.
Module attaches to the InMotion ARM™ Robot.
