I. KT-1 Neuromuscular Stimulator Product Overview

The KT series neuromuscular stimulator consists of two models: KT-1 and KT-2. The KT-1 is a well-established product that our company has been producing for many years since its establishment.

The KT-1 neuromuscular stimulator is designed based on low-frequency pulse electrotherapy and tailored to the physiological and pathological characteristics of neuromuscular tissues. It selectively applies bidirectional pulse waves of different frequencies to various muscle fiber tissues.

This product features four independent treatment channels, allowing simultaneous use by multiple users or multi-site treatment for a single patient. The treatment method utilizes skin electrodes.

II. Structural Composition

This product consists of a main unit, leads, and electrode pads.

III. Indications

This product provides analgesic and anti-inflammatory effects for conditions such as hyperosteogeny, lumbar muscle strain, sprains and contusions, and joint pain. It also stimulates muscles and reduces muscle tension. However, the body may easily develop adaptability.

IV. Contraindications

Acute suppurative inflammation, bleeding tendency, malignant tumors, thrombophlebitis, active tuberculosis, individuals with cardiac pacemakers, pregnant women, local foreign bodies, cardiac region, lower abdomen of pregnant women, and those intolerant to electrical current.
