ASTER PHYSIO AP CS-103A Professional Commercial Digital Therapeutic Ultrasonic

Dual Frequency 1&3 MHz

27 Treatment Programs/Protocols

Therapeutic ultrasound at 1 MHz and 3 MHz frequencies is widely used in physical therapy and rehabilitation to promote healing, reduce pain, and improve tissue function. Here’s how each frequency works and what it’s best used for:

—

🔬 Frequency Differences & Penetration Depth

| Frequency | Penetration Depth | Best For Treating |
|———-|——————-|——————-|
| 1 MHz | ~5 cm (deep tissues) | Muscles, joints, deep tendons |
| 3 MHz | ~1–2 cm (superficial tissues) | Ligaments, tendons, scar tissue, fascia |

💡 Key Therapeutic Uses

✅ 1 MHz Ultrasound
– Deep tissue heating: Enhances blood flow and tissue extensibility
– Pain relief: Especially effective for chronic low back pain and deep muscle aches
– Muscle strain recovery: Accelerates healing through increased circulation
– Joint stiffness: Improves mobility by warming deep structures

✅ 3 MHz Ultrasound
– Superficial tissue healing: Ideal for tendinopathies like rotator cuff or Achilles issues
– Scar tissue management: Softens fibrotic tissue and improves flexibility
– Ligament injuries: Promotes collagen remodeling and reduces inflammation
– Skin and fascia treatment: Enhances elasticity and reduces adhesions

🔥 Thermal vs Non-Thermal Effects

– Thermal effects: Continuous ultrasound raises tissue temperature, improving circulation and flexibility
– Non-thermal effects: Pulsed ultrasound promotes cellular repair via micro-cavitation and acoustic streaming
