Therapeutic Ultrasound

Therapeutic ultrasound helps to aid in pain relief, tissue healing, and improving mobility. There are two types of ultrasound: longwave and shortwave, each with unique characteristics and applications, tailored to different treatment goals.

Longwave Ultrasound 

​​

Longwave ultrasound typically operates at frequencies below 1 MHz, which allows for deeper tissue penetration. It is particularly effective in treating chronic conditions such as muscle and tendon injuries, ligament strains, or deep tissue inflammation. Longwave ultrasound helps to promote blood circulation, reduce swelling, and accelerate healing by reaching deeper structures, including muscles and joint capsules.

Benefits of Longwave Ultrasound:

  • Deep tissue penetration for chronic muscle, tendon, and ligament injuries

  • Enhances circulation and promotes healing of deeper structures

  • Reduces inflammation and swelling

  • Helps with scar tissue remodeling and tissue flexibility

​

Shortwave Ultrasound 

​

Shortwave ultrasound, operating at frequencies higher than 1 MHz, delivers energy to superficial tissues, such as skin, muscles, and tendons near the surface. It is ideal for treating acute conditions, including soft tissue injuries like sprains, strains, and post-operative recovery. The high-frequency waves generate heat in superficial tissues, which helps reduce pain, increase collagen production, and promote muscle relaxation.

Benefits of Shortwave Ultrasound:

  • Shallow tissue treatment, ideal for acute injuries and superficial conditions

  • Increases local blood flow and reduces pain by promoting muscle relaxation

  • Aids in collagen formation and wound healing

  • Reduces inflammation and accelerates recovery

When and Why We Use One Over the Other:

  • Longwave ultrasound is used for chronic conditions and deeper tissue issues, such as older muscle injuries, tendonitis, or deep joint inflammation. It is beneficial when treating conditions that require deep tissue healing, as it penetrates deeper layers.

  • Shortwave ultrasound is used for acute injuries, such as sprains, strains, and post-surgical recovery. It is more effective for superficial conditions and helps with immediate pain relief and muscle relaxation.

​

By selecting the appropriate type of ultrasound based on the tissue depth and condition being treated, I can provide the most effective and targeted therapy for each animal’s specific needs.
