IVES+ GD-611 — EMG-Triggered Functional Electrical Stimulator for Stroke

The OG Wellness IVES+ GD-611 is a CE-marked, clinically validated EMG-based functional electrical stimulator (FES) designed for the rehabilitation of upper and lower limb paralysis in patients with stroke (cerebrovascular accident), spinal cord injury, multiple sclerosis, and other neurological conditions causing motor impairment. IVES is an Integrated Volitional control Electrical Stimulator for upper- or lower-limb rehabilitation of patients with paralysis caused by cerebrovascular diseases or locomotive disabilities.

Six Treatment Modes — Full Clinical Versatility in One Device

The GD-611 has a total of six treatment modes, with Power Assist mode being the core mode, along with External Assist, Trigger, External Trigger, Normal, and Sensor Trigger modes. A single stimulator allows the therapist to cope with a variety of patient conditions and carry out rehabilitation aimed at reducing muscular atrophy and pain.

① Power Assist Mode (Core Mode) The GD-611's flagship mode. Electrical stimulation is output in real time in proportion to the EMG signal in the body part being treated. Weak voluntary effort produces mild stimulation; stronger effort produces stronger stimulation — creating a therapeutic feedback loop that maximizes neuromuscular re-education at every level of residual function. 

② External Assist Mode (GD-611 exclusive — requires bipolar electrode cord) Electrical stimulation is delivered in proportion to the EMG signal in the untreated body part. By stimulating the paralyzed body part in proportion to the EMG signal in the healthy part, both sides are trained. This cross-limb mode drives stimulation of the paralyzed limb using the healthy limb's EMG signal — promoting bilateral cortical engagement comparable to mirror therapy. This mode is exclusive to the GD-611 and unavailable on the GD-612 patient sub-unit. 

③ Trigger Mode When the EMG signal of the treated body part reaches a set threshold, electrical stimulation is delivered according to the set parameters. A standardized stimulation burst is triggered once voluntary effort crosses a defined EMG threshold — suited to patients requiring consistent stimulation patterns rather than proportional output. 

④ External Trigger Mode (GD-611 exclusive — requires bipolar electrode cord) When the muscle action potential in the untreated body part reaches a set threshold, electrical stimulation is delivered to the treated body part according to the set parameters. The healthy limb acts as the threshold trigger, driving therapy in the paralyzed limb — another GD-611-exclusive cross-limb mode for severe unilateral paralysis. 

⑤ Normal Mode Conventional programmed electrical stimulation delivered at set parameters without EMG feedback. Suitable for patients in the earliest acute stages where voluntary EMG signals are undetectable, or for pain management and disuse atrophy prevention.

⑥ Sensor Trigger Mode (requires Gait Sensor accessory) Electrical stimulation is initiated and terminated based on the response of the gait sensor. When the gait sensor detects that the patient's heel has lifted off the floor, stimulation is delivered according to the set parameters. This gait-synchronized FES mode is the primary lower limb rehabilitation mode of the GD-611, making it clinically effective for foot drop management in stroke and neurological patients — delivering peroneal nerve stimulation precisely timed to the swing phase of gait.

Original IVES Electrode Technology

In Power Assist Mode, a 3-pole gel electrode cord consisting of the IVES 2-pole gel electrode in combination with the IVES gel electrode is used. The IVES 2-pole gel electrode is the original electrode which detects the EMG signal. This proprietary design achieves simultaneous EMG detection and electrical stimulation delivery from the same electrode site. The fixed distance between IVES's bipolar gel electrodes makes it easy to precisely duplicate the desired electrode positioning over multiple treatments — ensuring consistent EMG detection sensitivity and stimulation delivery across sessions, enabling meaningful clinical progress tracking over time. 

45-Patient Storage with Named Profile Recall

IVES can store treatment settings for up to 45 patients. Names can be assigned for easy recall, eliminating the need to manually enter the settings each and every visit. In busy clinical environments where multiple patients share the same GD-611 throughout the day, this multi-patient storage dramatically reduces therapist setup time and eliminates transcription errors. Patient usage history — total treatment time, number of stimulation events, and cumulative stimulation duration — is automatically logged and viewable from the GD-611, supporting clinical documentation and compliance monitoring.
