Intended Use

Interferential and Premodulated Modes: Pain relief for: Symptomatic relief of chronic intractable pain and/or management of traumatic or post surgical pain. Ultrasound Therapy: Ultrasound therapy is available from the HF54 and indicated for: Applying therapeutic deep heat within body tissues for the treatment of selected chronic and sub-chronic medical conditions such as: Relief of pain, Muscle Spasms, joint contractures. The combination ultrasound & electrotherapy modes offer deep heat for pain management (ultrasound therapy) at the same time that electrical stimulation for either pain management or muscle stimulation is being delivered. Two electrotherapy modes utilizing Premodulated IFC can be utilized at a time in conjunction with the ultrasound mode. These are using One or two ultrasound applicators. The second ultrasound applicator is optional. Infrared Therapy (using optional HF023): An Infrared Therapy Probe is available as an optional accessory (HF023) for use with the Hill Laboratories HF54 Combination Ultrasound Interferential and premodulated stimulation system or for stand-alone use with an optional external medical grade, isolated power supply. It is used to provide topical heating for: Temporary increases in local blood flow and circulation, Temporary relief of minor muscle and joint aches, Temporary relief of pain and stiffness, Relaxation of muscles, Temporary relief (or relaxation) of muscle spasms, Temporary relief of minor pain and stiffness associated with arthritis.

Device Story

HF54 is a multi-modality physical medicine device combining ultrasonic diathermy, interferential current (IFC) stimulation, and optional infrared light therapy. Device inputs include user-selected parameters for ultrasound intensity/frequency and electrical stimulation waveforms. System transforms these inputs into therapeutic deep heat (ultrasound), muscle stimulation, or pain management currents (IFC/premodulated). Infrared probe (HF023) provides topical heating. Operated by qualified therapists in clinical settings. Output is delivered via ultrasound applicators, electrodes, or light probe. Healthcare providers use outputs to manage pain, reduce muscle spasms, and improve circulation. Benefits include non-invasive management of chronic/traumatic pain and musculoskeletal conditions.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on bench testing, compliance with mandatory standards (21 CFR 1050.10), and consensus standards (IEC 60601-1, 60601-1-2, 60601-2-5, 60601-2-10).

Technological Characteristics

Combination system for ultrasonic diathermy, IFC/premodulated stimulation, and infrared therapy. Complies with IEC 60601-1 (safety), IEC 60601-1-2 (EMC), IEC 60601-2-5 (ultrasound), and IEC 60601-2-10 (stimulators). Features include ultrasound applicators, electrical stimulation outputs, and optional infrared light probe. Device is intended for professional use by therapists.

Indications for Use

Indicated for patients requiring symptomatic relief of chronic intractable pain, management of traumatic or post-surgical pain, relief of muscle spasms, and joint contractures. Infrared therapy indicated for temporary relief of minor muscle/joint aches, pain, stiffness, and muscle spasms, and for increasing local blood flow/circulation.

Regulatory Classification

Identification

An ultrasonic diathermy for use in applying therapeutic deep heat for selected medical conditions is a device that applies to specific areas of the body ultrasonic energy at a frequency beyond 20 kilohertz and that is intended to generate deep heat within body tissues for the treatment of selected medical conditions such as relief of pain, muscle spasms, and joint contractures, but not for the treatment of malignancies.

#### Substantial Equivalence (SE) Rationale 12.1

The HF54 offers electrical stimulation, ultrasonic therapy and/or combination of the two and shares the same or similar basic characteristics including waveforms, operating frequencies and the same use in physical medicine and neurology as the predicate device. The new device and the predicate device are intended to be used by a qualified therapist.

The light wavelengths (visible and infrared) and output intensities for the HF023 Infrared therapy probe are the same as the predicate device's Infrared therapy probe cleared under K031239.

The methods of application and intended use/indications for use are the same and the same patient population is intended to be treated by the new device and the predicate device.

The ultrasound output and electrical stimulation currents are consistent with FDA guidance and international standards. The predicate device claims compliance to the same standards.

The materials used in construction of the device and the method of information display are similar. The measured parameters for the proposed HF54 are the same as those displayed on the predicate devices.

#### Conclusion 12.2

The proposed HF54 including HF023 Infrared Therapy probe is Substantially Equivalent to the Dynatronics Solaris device cleared under K031329.
