Clinical-Grade Therapeutic Ultrasound  |  1 MHz  |  Pulsed & Continuous Modes  |  3 Intensity Settings  |  Pre-Warming Soundhead to 95°F  |  IPX7 Waterproof Soundhead  |  5/10/15 Minute Timer  |  Up to 6 cm Tissue Penetration  |  Complete Kit Included  |  6-Month Warranty

A clinical-grade portable therapeutic ultrasound device for professional and home care use. The US Pro 2000 2nd Edition delivers 1 MHz ultrasound energy deep into body tissue — inducing vasodilation, increasing local blood flow, and providing evidence-based relief of musculoskeletal pain, muscle spasm, and joint stiffness. Three output intensity settings, pulsed and continuous operating modes, and three timer selections provide broad treatment flexibility for different clinical presentations. The aluminum soundhead pre-warms to 95°F for patient comfort before therapy begins, then deactivates during active treatment to allow optimal therapeutic delivery. The soundhead is rated IPX7 waterproof for underwater therapy applications. Maximum tissue penetration depth approximately 6 cm. Includes ultrasound gel, AC/DC adapter, hard carrying case, quick-start guide, and instruction manual. 6-month warranty.

Technical Specifications

Key Features

• 1 MHz therapeutic frequency — penetrates deep tissue to approximately 6 cm; appropriate for treatment of muscles, tendons, ligaments, and periarticular tissue below the skin surface
• Three output intensity settings — Low (0.8 W/cm²), Medium (1.0 W/cm²), High (1.2 W/cm²); allows the clinician or user to match treatment intensity to tissue depth, condition acuity, and patient tolerance
• Pulsed and continuous modes — pulsed mode delivers mechanical energy with reduced thermal effect; continuous mode at 100% duty cycle delivers both thermal and mechanical energy for deep tissue heating
• Pre-warming soundhead — heats to 95°F before therapy begins for patient comfort; automatically deactivates once therapy is engaged so the warmth does not interfere with therapeutic ultrasound delivery
• Three timer settings — 5, 10, and 15 minutes; covers standard clinical treatment session lengths
• IPX7 waterproof soundhead — aluminum soundhead rated for submersion in underwater therapy applications up to 30 minutes at 1 meter depth; the device body is not waterproof — only the metal soundhead portion
• Ergonomic soundhead design — shaped for easy handling and consistent skin contact during treatment
• Portable and compact — clinical-grade performance in a format suitable for clinic, home care, or travel use
• Complete kit — device, 8-oz ultrasound gel, AC/DC adapter, hard carrying case, quick-start guide, and instruction manual
• 6-month warranty

Clinical FAQs

What is the difference between pulsed mode and continuous mode on the US Pro 2000?

The US Pro 2000 operates in two distinct modes that produce different therapeutic effects. In continuous mode (100% duty cycle), the ultrasound energy is delivered without interruption — the consistent energy transfer generates both thermal and mechanical effects in the tissue. The thermal effect produces deep tissue heating at tissue boundaries (skin, adipose tissue, and bone interfaces), stimulating local blood flow through vasodilation and increasing tissue extensibility. Continuous mode is generally indicated for chronic conditions where deep heating is the primary therapeutic goal — chronic muscle tightness, joint contracture, scar tissue, and subacute to chronic pain. In pulsed mode, the ultrasound energy cycles on and off at duty cycles of 30–50% depending on the intensity setting selected. The interrupted delivery reduces thermal accumulation and shifts the primary effect toward non-thermal mechanical mechanisms — microstreaming and acoustic cavitation — which influence cell membrane permeability, tissue fluid dynamics, and inflammatory mediator activity. Pulsed mode is generally preferred for acute or subacute conditions where thermal effects should be minimized — acute inflammation, fresh soft tissue injury, or situations where the treatment area is over a bony prominence where heat accumulation would be poorly tolerated. The three intensity settings on the US Pro 2000 interact with mode selection: the same intensity setting produces different effects depending on whether pulsed or continuous mode is selected.

What does the soundhead pre-warming feature do and why does it turn off when therapy begins?

The pre-warming feature heats the aluminum soundhead to approximately 95°F before the therapy session starts — so when the clinician or user first applies the soundhead to the patient's skin, the contact is warm rather than cold aluminum, which can be jarring and tense the superficial muscle. The pre-warming is a comfort measure only and has no therapeutic function. The pre-warming turns off automatically when the therapy timer is activated because the heat from the pre-warming element could interfere with the thermal effects of the ultrasound energy itself, making it impossible to accurately control the thermal dose being delivered to the tissue. Therapeutic ultrasound produces its own heat through sound energy conversion in the tissue — the goal is controlled, precise deep tissue heating from acoustic energy, not surface warming from a resistive heating element. Having both operating simultaneously would make the thermal effect less predictable. The sequence is therefore: pre-warm the soundhead → apply to skin → start timer → pre-warming deactivates → therapeutic ultrasound delivers controlled energy to the tissue.

What conditions is therapeutic ultrasound used for and is a prescription required?

Therapeutic ultrasound at 1 MHz is used in clinical practice for a range of musculoskeletal conditions. Common clinical applications include chronic muscle tension and trigger points, tendinopathy and tendon inflammation (rotator cuff, Achilles, patellar, plantar fascia), ligament sprains in subacute and chronic phases, bursitis, joint contracture and scar tissue, and conditions associated with reduced tissue extensibility such as frozen shoulder (adhesive capsulitis). At 1 MHz, the device penetrates to approximately 6 cm — appropriate for deeper tissue structures including shoulder girdle muscles, hip muscles, lumbar paraspinals, and large joint periarticular tissue. At 3 MHz (not available on this device), penetration is shallower at 1–2 cm for more superficial structures. The US Pro 2000 is marketed for both professional and home care use. For clinical application, patient selection, mode selection, intensity, duty cycle, and treatment duration should be determined by a licensed physical therapist, chiropractor, or other qualified clinician with training in therapeutic modalities. Individuals using the device for home care should have their treatment parameters established by a qualified clinician before self-administering. A prescription is not required for purchase, but clinical guidance for appropriate use is strongly recommended. Call our team at 1-866-218-0902 with questions about this product.
