Balance rehabilitation system G9

arm mobility

Overview
The AIDFLEX G9 Dynamic Arm Support Trainer compensates for arm weight to facilitate guided active movement in patients with upper-limb motor impairments. The device supports proximal shoulder movements while allowing small shoulder-girdle, wrist and finger motions required for manipulation and grasping. Minimal voluntary activation of shoulder and hand musculature is sufficient to use the trainer.

Key product statement
Antigravity dynamic arm support providing full range of motion and adjustable unloading.

Start using the machine in three simple steps

• Adjust the device height — height is easily adjusted for seated or standing use.
• Secure the forearm on the armrest — soft cuff stabilizes the forearm in the chosen position.
• Select support intensity — a rotary control sets the level of antigravity assistance.

The following diseases / conditions can be treated on the G9

• Stroke (post-stroke hemiparesis)
• Spinal cord injury (SCI)
• Polyneuropathy
• Shoulder injuries and impingement
• Elbow injuries
• Glenohumeral arthrosis
• Shoulder capsule lesions
• Upper-arm hemiparesis
• Use in healthy workers needing prolonged arm abduction

Intended use
The G9 is intended for clinical and home rehabilitation as well as workplace or office support. It is suitable for physical therapy and occupational therapy programs with progressive adjustment of load and range of motion. The device is universal for right and left arms and for seated or standing positions; it can also serve as ergonomic unloading support for healthy users required to hold the arms abducted for extended periods.

Advantages
Fine-frequency adjustment of the antigravity effect enables tailored unloading for motor rehabilitation of the upper extremity.

• Preserves natural movement patterns — promotes activation of cortical motor areas involved in complex sequences.
• Reduces muscular load — unloads neck and shoulder muscles during prolonged tasks.
• Maintains joint mobility — regular guided movement helps prevent contractures and deformities.
• Supports rehabilitation progression — comfortable assistance encourages active participation.
• Facilitates development of independent movements — dynamic unloading aids relearning of coordination and precision.
• Stable support mechanism — ensures consistent assistance for precise therapeutic exercises.

Technology / Functional notes
Antigravity assistance is delivered via low-inertia springs controlled by fine-frequency signals to provide uniform compensating force. Smooth adjustment of unloading force permits individualized support; the mechanism allows safe standing exercises while preserving balance and comfort.
