Shockwave therapy is a non-invasive treatment that stimulates the body’s natural healing processes. It involves delivering acoustic waves to targeted areas. This therapy has shown promise in addressing various conditions, including the reduction and remodeling of scar tissue, offering a non-surgical alternative to improve the appearance and function of scarred areas.
Understanding Scar Tissue
Scar tissue is a type of fibrous connective tissue that forms to replace normal tissue after an injury, surgery, or inflammation. It is primarily composed of collagen fibers, which, unlike the organized, multidirectional pattern of healthy skin, are typically arranged in a single direction. This different structure can make scar tissue less elastic and flexible than the original tissue.
The formation of scar tissue is a natural part of the body’s healing response, serving to close wounds and prevent infection. However, excessive scar tissue can lead to various issues, such as pain, itching, stiffness, and restricted movement. Internal scar tissue, like adhesions, can also form after surgery or injury, potentially causing pain and limiting the function of affected organs or joints.
How Shockwave Therapy Works
Shockwave therapy utilizes acoustic waves, generated by a specialized device and directed toward the affected tissue. As these waves penetrate the skin, they exert mechanical pressure on the scar tissue. This mechanical disruption helps break down the dense, fibrous structure of the scar tissue into smaller fragments.
The therapy also stimulates cellular activities within the treated area. It promotes neovascularization, the formation of new blood vessels, which increases blood flow to the damaged tissue. This enhanced circulation delivers essential nutrients, oxygen, and immune cells, aiding in the removal of scar tissue debris and facilitating the growth of new, healthy tissue. Shockwave therapy stimulates cells to release growth factors and triggers an inflammatory response, helping the body replace old scar tissue with more functional tissue. It also encourages collagen remodeling, improving tissue quality and elasticity.
Types of Scars Treated
Shockwave therapy treats a variety of scar types. It benefits hypertrophic scars, which are raised, red, and thickened scars remaining within the original wound boundaries. Keloid scars, also raised but extending beyond the injury site, can also be addressed.
The therapy has been investigated for its effects on post-surgical scars, including those from C-sections, where it can help accelerate healing and improve the appearance of older scars. Scars resulting from burns, often leading to contractures that restrict movement, may also benefit from shockwave therapy by improving pliability and reducing color mismatch. Additionally, fibrotic tissue associated with chronic musculoskeletal conditions or old injuries, like adhesions that can form internally, can be targeted to improve mobility and reduce discomfort.
The Treatment Process and Outcomes
During a shockwave therapy session, a healthcare professional applies a gel to the area. A handheld device then delivers acoustic waves directly to the scarred tissue. Most patients tolerate the sensation well, often describing it as a mild tapping or tingling, rather than pain.
The number of sessions required varies based on scar type and severity. Improvements are often observed after a few treatments, with noticeable changes occurring as early as six weeks. Each session lasts between 15 to 30 minutes, and patients experience minimal downtime, resuming daily activities immediately. Mild side effects may include temporary redness, swelling, or slight discomfort in the treated area, which subside within a few hours.
Outcomes from shockwave therapy for scar tissue include improved elasticity and pliability of the tissue, reduced pain and discomfort, and an increase in the range of motion, particularly for scars that limit movement. Many patients also report an improvement in the cosmetic appearance of their scars, including reduced height, improved pigmentation, and a less noticeable overall look.
