Effectiveness of Ultrasound Therapy for Carpal Tunnel Syndrome

Ultrasound Therapy

Hello, Director! Regarding the treatment of carpal tunnel syndrome, during the 3-minute ultrasound therapy, I feel very sore and soft, and the dosage is consistently kept at the lowest level.
Will this still achieve the desired therapeutic effect? Thank you!

Hello, in response to your question, I would like to provide the following suggestions:
1.
The general treatment dosage should be approximately 0.6 W/cm² to 1.5 W/cm².

2.
If you feel that there is not much improvement or if the flexibility is insufficient, and you cannot overcome the sensation of soreness, you may consider the following treatments:
<1.> Switch to intermittent ultrasound output, which will prevent heat accumulation in the tissues and reduce the sensation of soreness.

<2.> Increase the area treated with ultrasound and decrease the duration of application, which can also help reduce the sensation of soreness.

<3.> Consider using other laser devices that provide similar effects as an alternative.

More Info

Ultrasound therapy has been widely studied and utilized as a treatment modality for various musculoskeletal conditions, including Carpal Tunnel Syndrome (CTS). CTS is characterized by the compression of the median nerve as it passes through the wrist, leading to symptoms such as pain, numbness, and tingling in the hand and fingers. The effectiveness of ultrasound therapy in treating CTS can vary based on several factors, including the duration of treatment, frequency, intensity, and the specific parameters of the ultrasound used.

In your case, you mentioned that during the 3-minute ultrasound therapy sessions, you felt a significant amount of discomfort, describing it as "very sore and soft." This sensation can be a normal response to ultrasound therapy, especially if the treatment is targeting inflamed or irritated tissues. However, it is essential to ensure that the intensity and duration of the ultrasound are appropriate for your condition. Generally, ultrasound therapy for CTS is administered at a frequency of 1 MHz or 3 MHz, with a duty cycle that can be continuous or pulsed, depending on the treatment goals.

The typical treatment duration for ultrasound therapy can range from 5 to 10 minutes per session, and it is often recommended to have multiple sessions per week for several weeks to achieve optimal results. If you are only receiving 3 minutes of treatment, it may not be sufficient to provide the therapeutic benefits associated with ultrasound therapy. The effectiveness of treatment can be influenced by the total energy delivered to the tissue, which is a function of both the intensity and the duration of the ultrasound application.

Moreover, the sensation of discomfort during treatment should be monitored closely. If the discomfort is too intense, it may indicate that the intensity is set too high or that the treatment is not being applied correctly. It is crucial to communicate any discomfort to your therapist, as they may need to adjust the settings or technique to ensure that the treatment is both effective and tolerable.

In addition to ultrasound therapy, a comprehensive treatment plan for Carpal Tunnel Syndrome may include other modalities such as splinting, corticosteroid injections, physical therapy, and ergonomic adjustments to reduce strain on the wrist. Splinting, especially at night, can help keep the wrist in a neutral position, reducing pressure on the median nerve. Physical therapy can also provide exercises to strengthen the wrist and hand muscles, improving overall function and reducing symptoms.

In conclusion, while ultrasound therapy can be an effective treatment for Carpal Tunnel Syndrome, the parameters of the treatment, including duration and intensity, play a crucial role in its effectiveness. If you feel that the current treatment duration of 3 minutes is insufficient, it would be advisable to discuss this with your healthcare provider or therapist. They may consider adjusting the treatment plan to include longer sessions or additional therapeutic modalities to enhance your recovery. Always ensure that any discomfort during treatment is communicated to your therapist to tailor the therapy to your needs effectively.
