I. MTZ-M Computer Intermediate Frequency Electrotherapy Device Product Overview

The MTZ-M Computer Intermediate Frequency Electrotherapy Device utilizes the principle of low-frequency modulated intermediate frequency current. It is pre-programmed with 20 treatment protocols for common and frequently occurring diseases, featuring strong penetration,

no electrolysis, improvement of local blood circulation, analgesia, anti-inflammatory effects, and more. This device is microprocessor-controlled and offers various modulation combinations such as continuous modulation, intermittent modulation, break modulation, and variable modulation,

enabling patients to experience stimulating and massaging effects on the body such as pushing, grasping, tapping, pulling, pressing, kneading, patting, and vibration. It also includes pulsed direct current drug iontophoresis functionality, allowing for drug penetration therapy.

II. Structural Composition:This product consists of a main unit, leads, and electrode pads.

III. MTZ-M Computer Intermediate Frequency Electrotherapy Device Scope of Application

This product can stimulate neuromuscular tissue, soften scars, release adhesions, and has analgesic, anti-inflammatory, and local blood circulation improvement effects, along with

drug iontophoresis functionality. However, the body may easily develop adaptation.

Examples of Indications:

Neuromuscular stimulation: Muscle dysfunction after nerve or muscle injury, disuse muscle atrophy, constipation, vocal cord paralysis, gastroptosis.

Analgesic and anti-inflammatory effects: Frozen shoulder, lateral epicondylitis, cervical spondylosis, lumbar disc herniation, degenerative osteoarthropathy, rheumatoid arthritis,

rheumatoid arthritis, sprains, contusions, myofibrositis, muscle strain, pelvic inflammatory disease, adnexitis, chronic pharyngitis, mammary gland hyperplasia, sciatica, peripheral

nerve injuries, joint contractures, chronic prostatitis, delayed union of fractures.

Scar softening and adhesion release: Scars, scar contractures, postoperative adhesions, intestinal adhesions, stenosing tenosynovitis, post-injection indurations.
