Which modality is commonly used to treat tendinopathies by promoting tissue healing and reducing pain?

• A. Cryotherapy
• B. Therapeutic ultrasound
• C. Electrical stimulation
• D. Manual therapy

Answer: (B)

Therapeutic ultrasound is commonly used to treat tendinopathies because it can actively support tissue healing while also reducing pain. The energy from ultrasound heats the target tissue, increasing blood flow, metabolic activity, and collagen fiber extensibility, all of which help the tendon repair process. It also has non-thermal effects, such as cavitation and micro-streaming, that can enhance cellular activity and collagen synthesis, promoting healing at the cellular level.

Cryotherapy mainly offers short-term pain relief and reduced swelling without actively stimulating long-term tendon healing. Electrical stimulation is typically used for pain modulation and muscle activation rather than directly promoting tendon tissue repair. Manual therapy can improve mobility and decrease pain through soft tissue and joint techniques, but it does not provide the same direct, tissue-level healing stimulus that ultrasound offers.
