Ami Life Neuromuscular Stimulator

Ami Life is a modern medical device for the treatment and rehabilitation of dysphagia (swallowing difficulties). Developed as part of the Globus product family, it is a CE-certified medical device.

The Ami Life device is compact (160×99×35.4 mm) and lightweight (404 g). It features four independent channels for electrostimulation, operating at 0–20 mA. The stimulation waveform is rectangular, biphasic, symmetric, and compensated, with a frequency range of 1–80 Hz and pulse widths of 80–260 µs.

Target group and application

Ami Life is primarily designed for patients with swallowing difficulties. It is recommended for complications of neurological and muscular disorders, cardiovascular and cerebrovascular events, respiratory diseases, iatrogenic conditions, and fibrosis/stenosis caused by radiotherapy. It is particularly effective post-stroke, for dysphagia following intubation, and after head or neck injuries.

Benefits for professionals

For therapists, Ami Life offers precise, well-documented treatments with adjustable and trackable stimulation parameters. Built-in programs include sensory (120 µs, 80 Hz), sensorimotor (200 µs, 80 Hz), and motor (260 µs, 80 Hz) protocols optimized for various therapeutic goals. The device stores data from the last ten treatments for easy monitoring.

Patient benefits

Ami Life provides comfortable and safe therapy. Battery-powered and portable, it can be used at home under medical supervision. Treatments are non-invasive and cause minimal discomfort when parameters are set correctly, helping restore swallowing function, improve quality of life, and reduce dysphagia-related risks.

Treatment protocols and mechanism

• Sensory program (120 µs, 80 Hz) focuses on sensation enhancement and neural stimulation.
• Sensorimotor program (200 µs, 80 Hz) combines sensory and motor nerve effects.
• Motor program (260 µs, 80 Hz) targets muscle function improvement.

During therapy, electrodes are placed on the front of the neck and face to stimulate muscles and nerves involved in swallowing.

Application technology and procedure

Proper electrode placement is critical. The user manual provides detailed guidance and illustrations for correct positioning relative to the jawline, hyoid bone, thyroid cartilage, and cricoid cartilage. Symmetry must be maintained both laterally and along the midline.

Safety and contraindications

• Not for use on skin lesions or tumors at the treatment site.
• Contraindicated if swallowing is impaired by structural or neurological abnormalities.
• Not to be used on active infection sites or over the carotid sinus nerves, especially in patients with known carotid sinus hypersensitivity.

Usage protocol

Before use, clean the skin thoroughly. Apply electrodes only to intact, clean, dry skin. Ensure adequate electrode adhesion before starting. Gradually increase stimulation intensity while monitoring patient response. Treatment duration and frequency depend on patient condition and therapeutic goals.

Documentation and follow-up

Ami Life enables documentation and tracking of treatments. It stores data from the last ten sessions and allows saving custom programs, aiding therapy evaluation and protocol refinement.

Ami Life in modern rehabilitation

Ami Life plays a vital role in modern rehabilitation, providing effective therapy for patients less responsive to traditional methods. It is especially valuable when restoring swallowing function is crucial to quality of life.

Research and clinical experience

Clinical studies support the device’s efficacy, particularly in post-stroke dysphagia. Properly applied electrostimulation significantly improves swallowing function and reduces dysphagia complications.

Future developments

Ami Life is under continuous development, with ongoing optimizations and new features based on user feedback. Future enhancements may include refined treatment protocols and new therapeutic applications.

Recommendation

Ami Life is a complex, versatile medical device offering significant support for dysphagia therapy. With correct use and adherence to safety guidelines, it is an effective tool for professionals and patients in rehabilitation.
