Laser vs Shockwave: Which Is Better for Tendon Injuries?
Dr. Ben Stokes • April 6, 2026

Persistent tendon pain can be frustrating, especially for active individuals who want to stay consistent with training and exercise. Tendon injuries such as Achilles tendinopathy, plantar fasciitis, and tennis elbow often develop gradually and may take longer to heal than muscle injuries.

In recent years, two advanced treatment options have gained attention in orthopedic rehabilitation and sports medicine: high-intensity laser therapy (Class IV laser) and extracorporeal shockwave therapy (ESWT) .

Both treatments aim to support the body’s natural healing processes and reduce pain. However, they operate through distinct biological mechanisms, and each may be better suited to certain types of injuries.

Understanding how these therapies work can help patients make informed decisions about their treatment options.

Understanding Tendon Injuries and Regenerative Modalities

Tendons connect muscles to bones and help transfer force during movement. Because they experience repetitive loading during activities like running, jumping, or lifting, tendons are especially vulnerable to overuse injuries.

Many chronic tendon injuries are not purely inflammatory conditions. Instead, they often involve degenerative changes within the tendon , sometimes referred to as tendinopathy.

Common tendon injuries include:

These injuries may develop when tissues are exposed to stress beyond their capacity to recover.

What Is Shockwave Therapy?

Shockwave therapy uses acoustic pressure waves to stimulate healing within injured tissue.

These waves travel through the skin and interact with the damaged tendon. The mechanical stimulation creates small micro-stresses in the tissue that activate the body’s natural healing response.

Research suggests that shockwave therapy may stimulate:

  • Growth factor release

  • New blood vessel formation

  • Collagen remodeling

  • Breakdown of calcifications and scar tissue

Because of these effects, shockwave therapy is often used for chronic tendon conditions that have not responded to traditional treatments.

What Is High-Intensity Laser Therapy?

High-intensity laser therapy uses light energy to stimulate cellular activity through a process called photobiomodulation.

When laser light penetrates the tissue, it interacts with mitochondria inside cells. This increases ATP (adenosine triphosphate) production, the energy source cells use for repair and regeneration.

Laser therapy may help:

  • Increase circulation

  • Reduce inflammation

  • Stimulate cellular metabolism

  • Decrease nerve sensitivity and pain

Laser therapy is commonly used for muscle injuries, joint irritation, and inflammatory conditions , although it can also support tendon healing.-

Key Differences Between Laser Therapy and Shockwave Therapy

Although both treatments support healing, they do so in different ways.

Feature Shockwave Therapy High-Intensity Laser Therapy

Energy Type Acoustic pressure waves Light energy

Main Biological Effect Stimulates tissue regeneration Enhances cellular metabolism

Best for Chronic tendon injuries Pain & inflammation

Sensation Mild mechanical tapping Gentle warming sensation

Typical Treatment Time 5–10 minutes 5–15 minutes

Both treatments are non-invasive and typically performed in an outpatient setting.

When Shockwave Therapy May Be the Better Option

Shockwave therapy is frequently used for chronic tendon injuries where healing has stalled .

Examples include:

These conditions often involve degenerative tendon tissue rather than acute inflammation. Shockwave therapy can help stimulate tissue remodeling and promote healing.

When Laser Therapy May Be More Helpful

Laser therapy may be particularly helpful when pain and inflammation are prominent symptoms .

Examples include:

Because laser therapy can reduce pain and inflammation, it may allow patients to participate more comfortably in rehabilitation exercises.

Why Some Patients Benefit From Both Treatments

In many cases, the two treatments are complementary rather than competing options .

For example, a patient with Achilles tendinopathy might receive:

  • Shockwave therapy to stimulate tendon remodeling

  • Laser therapy to reduce inflammation and pain

This combined approach can help address both the biological healing process and symptom management .

Why Physical Therapy Still Matters

While advanced treatments can support healing, they are most effective when combined with rehabilitation.

Physical therapy focuses on improving:

  • Strength

  • Mobility

  • Tendon load capacity

  • Movement mechanics

For musculoskeletal injuries, progressive loading exercises are often essential for long-term recovery.

Without addressing these underlying factors, symptoms may return even if pain temporarily improves.

Which Treatment Is Right for You?

The most appropriate treatment depends on several factors, including:

  • The type of injury

  • How long symptoms have been present

  • The severity of tissue irritation

  • Activity level and training goals

A thorough evaluation helps determine whether you qualify for either treatment and, if so, which approach is most appropriate.

The Bottom Line

Both shockwave therapy and high-intensity laser therapy can be valuable tools for managing tendon injuries.

Shockwave therapy is often used for chronic tendon conditions that require stimulation to restart the healing process, while laser therapy can help reduce inflammation and improve cellular activity .

When combined with targeted physical therapy, these treatments may help patients recover more effectively and return to the activities they enjoy.

Considering Treatment for a Tendon Injury?

If you’re dealing with persistent tendon pain or an injury that hasn’t improved with rest, a thorough evaluation can help determine the most appropriate treatment approach.

At Tualatin Valley Physical Therapy , we work with active individuals to develop personalized rehabilitation plans focused on restoring strength, improving movement, and helping patients return safely to activity.

Laser Therapy vs Shockwave Therapy FAQs

  • Both treatments can support tendon healing, but they work through different mechanisms.
    Shockwave therapy is often used for chronic tendon injuries because it stimulates tissue regeneration and collagen remodeling. High-intensity laser therapy is frequently used to reduce pain and inflammation , which can make rehabilitation exercises easier to perform.

    The best treatment depends on the specific condition, how long symptoms have been present, and individual activity goals.

  • Shockwave therapy can create a mild tapping or pulsing sensation during treatment. Some patients describe temporary discomfort during the procedure, especially in sensitive areas.

    However, treatments are short (usually 5–10 minutes), and the intensity can be adjusted to maintain comfort.

  • No. Most patients report a gentle warming sensation during laser therapy treatments. The procedure is non-invasive and generally comfortable.

  • Treatment plans depend on the severity and duration of the injury. Some patients experience improvement earlier, while chronic conditions may require a longer treatment plan. These treatments are combined with physical therapy for optimal results.

  • No. Shockwave therapy and laser therapy are supportive treatments , not replacements for rehabilitation.

    For tendon injuries, progressive strengthening exercises and movement correction are often necessary to restore tendon capacity and prevent recurrence.

It's National Physical Therapy Month: Why PT Isn't Just for Pain October is National Physical Therapy Month, a time to recognize how physical therapists help people move better and live healthier at every stage of life. This year, we want to bust one of the biggest myths about our profession. Most people think of physical therapy as something you need after a torn ligament, a joint replacement, or a morning when you wake up and can't turn your head. Physical therapists are very good at helping with those things. But treating injuries is only half of what we do. Physical therapy is also one of the most effective, yet underused, tools in preventive health care. A physical therapist can help you move better, lower your risk of chronic disease, and protect your strength and independence for decades to come. Exercise Is the Most Powerful Medicine You Don't Need a Prescription For We all know exercise is good for us, but it's easy to underestimate how good it is. Researchers have called exercise "the real polypill" because no single medication benefits as many systems of the body at once. If physical activity could be packaged into a pill, it would be the most prescribed drug in the world. Regular physical activity: Supports mood and mental health. A large 2023 review of nearly 100 systematic reviews found that physical activity meaningfully reduces symptoms of depression, anxiety, and psychological distress across a wide range of adults. Lowers your risk of chronic disease. Being active reduces the risk of heart disease, stroke, high blood pressure, and type 2 diabetes. In a study of 1.44 million adults, higher leisure-time activity was linked to a lower risk of 13 different types of cancer. Helps protect you from serious illness. In a study of more than 65,000 adults whose activity was directly measured, people who got regular moderate activity were less likely to be hospitalized, admitted to intensive care, or die from COVID-19. Protects your brain. In the long-running Framingham Heart Study, adults who were most active in midlife (ages 45 to 64) had a 41% lower risk of dementia, and those most active later in life (ages 65 to 88) had a 45% lower risk, compared with the least active. Improves metabolic health and sleep. Regular activity improves insulin sensitivity (how well your body uses insulin to manage blood sugar), lowers blood pressure, and improves sleep quality. Yet according to the CDC, fewer than 1 in 4 American adults meet the federal guidelines for both aerobic and muscle-strengthening activity. That means at least 150 minutes of moderate aerobic activity per week, plus strength training at least two days per week. Why is that? For many people, moving regularly hurts, feels overwhelming, or simply doesn't fit into everyday life. That's where your physical therapist comes in. How a Physical Therapist Helps You Stay Active for Life To stay active, you first need to move comfortably and with confidence. Physical therapists are doctoral-trained experts in the human movement system. A thorough PT evaluation looks at how your whole body moves, not just where it hurts. From there, your PT can: Find and address the root causes of pain, stiffness, or recurring injuries Improve your strength, mobility, and balance Build an exercise plan that fits your body, your goals, and your schedule Your PT can also work alongside the rest of your health care team. If your physician has encouraged you to lower your blood pressure, improve your cholesterol, or bring down your HbA1c (a blood test that reflects your average blood sugar over about three months), your PT can design an exercise prescription that supports those goals safely, even if you're working around joint pain or a past injury. Think of Your PT the Way You Think of Your Dentist You don't wait for a toothache to see your dentist. Your movement health deserves the same kind of regular attention. A physical therapist can be your go-to for regular movement screenings, program updates as your goals change, and early attention to small aches before they become real injuries. As your body changes across the decades, or as your life shifts from training for 10Ks to keeping up with your grandkids, your PT can help you stay pain-free, capable, and healthy. Aging is inevitable. Losing your mobility, strength, and independence doesn't have to be. Frequently Asked Questions Do I need to be injured to see a physical therapist? No. Many people see a PT to get stronger, move better, start a new activity safely, or reduce their risk of future injury. Is preventive physical therapy only for older adults? Not at all. Runners, lifters, weekend athletes, and busy professionals all benefit from having a movement expert in their corner. The earlier you build healthy movement habits, the longer they pay off. What happens at a preventive PT visit? Your PT will review your health history and goals, assess how you move, and look at strength, mobility, and balance. You'll leave with a clear plan tailored to you. Your Movement Coach and Lifelong Partner You don't have to wait for pain to see a physical therapist. Whether you want to run your first 5K, get back in the gym safely, or stay strong and independent for years to come, your PT can help you get there.
