Description

A therapeutic modality using alternating current in the 1–10 kHz range to stimulate nerves and muscles, reduce pain, and promote tissue healing without significant skin resistance.

Main Uses

Primary clinical uses include pain modulation (e.g., chronic low back pain, osteoarthritis), reduction of muscle spasm and stiffness, enhancement of local blood circulation and tissue metabolism, facilitation of neuromuscular re-education post-stroke or injury, and adjunctive management of edema and delayed wound healing. Commonly applied in rehabilitation centers, physiotherapy clinics, and pain management units.

Normal Range

Medium-frequency electrotherapy (MFE) is a non-invasive physical therapy modality, not a diagnostic laboratory test; therefore, it has no numerical 'normal range' or quantitative biomarker values. Treatment parameters (e.g., frequency: 1–10 kHz, intensity: 0–100 mA adjustable, pulse width: 10–500 μs, duration: 10–30 minutes) are individually titrated based on patient tolerance and clinical goals—not standardized reference intervals.

Low Values - Possible Causes

N/A — MFE does not produce quantifiable 'low values'; however, subtherapeutic outcomes may result from inadequate dosage (e.g., insufficient intensity or duration), improper electrode placement, severe sensory neuropathy limiting perception, skin barrier issues (e.g., excessive dryness or callus), or device calibration error.

High Values - Possible Causes

N/A — MFE does not yield 'high values'; adverse responses (e.g., muscle twitching, pain, skin irritation) may occur due to excessive current intensity, prolonged treatment time, compromised skin integrity, underlying nerve hyperexcitability (e.g., in radiculopathy), or incorrect waveform selection (e.g., using dense-disperse mode at high amplitude without ramping).
