Carpal Tunnel Syndrome (CTS) is a common condition affecting the hand and wrist, characterized by pain, numbness, and tingling. It occurs when the median nerve, which runs through a narrow passageway in the wrist called the carpal tunnel, becomes compressed or irritated. While many treatment options exist, shockwave therapy is emerging as a non-invasive approach with potential to alleviate symptoms and promote healing.
Understanding Shockwave Therapy
Shockwave therapy utilizes high-energy acoustic waves to stimulate healing and reduce pain. These sound waves are generated by a device and delivered to the affected area. This transmission of mechanical energy into the tissues triggers a biological response. This mechanical stimulation activates the metabolic rate of cells, leading to tissue remodeling. There are different types of shockwave therapy, which vary in how the energy is delivered. The therapy has been used for various musculoskeletal conditions, including tendonitis and plantar fasciitis.
How It Addresses Carpal Tunnel
Shockwave therapy targets the tissues within the carpal tunnel to address median nerve compression. The high-energy pressure waves penetrate deep into the affected area, promoting increased blood circulation. This enhanced blood flow helps reduce inflammation and delivers essential healing nutrients to the compressed median nerve and surrounding structures.
The therapy also stimulates the body’s natural healing response by creating microtrauma, which can lead to the generation of new blood vessels and the release of growth factors. This process encourages tissue regeneration and the repair of damaged tendons and ligaments. Additionally, shockwave therapy can break down scar tissue and adhesions that may further compress the median nerve, improving flexibility and range of motion in the wrist.
What to Expect from Treatment
Patients undergoing shockwave therapy for carpal tunnel syndrome can expect a series of treatment sessions. A typical course involves 3 to 5 sessions, spaced a week apart, though this can vary based on individual needs and the severity of the condition. Each session lasts between 5 to 15 minutes.
During the procedure, a gel is applied to the skin over the carpal tunnel area, and a handheld device delivers the acoustic waves. Patients may experience sensations such as mild discomfort, a buzzing, or tapping feeling during the treatment. Discomfort usually subsides quickly after the session concludes. Patients can resume their daily activities without downtime. Minor, temporary side effects like redness, slight bruising, or soreness in the treated area are possible but generally resolve within a day or two.
Effectiveness and Suitability
Current scientific evidence suggests that shockwave therapy can be an effective non-invasive treatment for mild to moderate carpal tunnel syndrome. Studies have shown significant improvements in pain reduction, hand grip strength, and nerve conduction velocity in patients receiving shockwave therapy. Research indicates improvements in validated scores for pain, symptom severity, and functional status.
Shockwave therapy offers a non-surgical alternative, reducing risks associated with incisions or anesthesia. While conservative treatments like splinting and corticosteroid injections are common, and surgery is an option for severe cases, shockwave therapy provides a promising non-invasive choice before considering more invasive procedures. Good candidates for this therapy include those with mild to moderate CTS symptoms who seek a non-surgical approach or those who have not found adequate relief from other conservative treatments.
