Tendinopathy is a chronic tendon condition often triggered by repetitive stress or injury, leading to ongoing pain and reduced mobility. It affects millions in the U.S., contributing to missed work and rising healthcare costs. The condition is driven by a self-perpetuating cycle involving:
- Mechanical stress: Overloading tendons without adequate recovery causes structural damage.
- Chronic inflammation: Persistent inflammation disrupts healing and increases pain.
- Vascular changes: Abnormal blood vessel and nerve growth worsen symptoms and hinder repair.
Recent research highlights new factors like intratendinous pressure and metabolic health that may influence tendon dysfunction. Effective treatment requires addressing these interconnected issues through targeted therapies such as chiropractic adjustments, Graston technique, dry needling, and shockwave therapy. Combining these approaches can disrupt the cycle and improve recovery.

Main Causes: Mechanical Stress, Inflammation, and Blood Flow Changes
Tendinopathy is driven by a combination of mechanical stress, inflammation, and changes in blood flow. These interconnected factors create a persistent condition that can be challenging to manage.
How Mechanical Stress Contributes to Tendinopathy
Mechanical stress is the primary factor behind the development of tendinopathy. When tendons are subjected to forces beyond their ability to adapt, their structure starts to break down. This isn’t limited to sudden injuries – repeated overloading without adequate recovery leads to cumulative microtrauma.
Tendons are built to handle heavy loads, but they require sufficient recovery time between stress episodes. If this balance is disrupted, tenocytes – the cells responsible for maintaining the tendon structure – begin producing abnormal proteins and inflammatory substances. Over time, the tendon matrix deteriorates, weakening its overall integrity.
One of the most damaging aspects of mechanical stress is its cumulative effect. While each individual strain might seem insignificant, the repeated stress overwhelms the tendon’s natural repair processes. This damage isn’t confined to the affected tendon; surrounding muscles and joints often adjust their movement patterns to compensate, which can place additional strain on other tendons. These biomechanical shifts further exacerbate the problem, setting the stage for inflammation and delayed recovery.
Inflammation: A Double-Edged Sword
Inflammation plays a complicated role in tendinopathy, differing significantly from the typical healing response seen in acute injuries. While inflammation is usually a short-term process that aids recovery, in tendinopathy, it becomes chronic and counterproductive.
Chronic inflammation creates a harmful environment within the tendon. Instead of supporting repair, persistent inflammatory chemicals activate pain receptors, prolonging discomfort. This ongoing inflammation also alters the tendon’s mechanical properties, making it stiffer and less flexible. As a result, the tendon becomes more vulnerable to further damage, creating a vicious cycle.
Studies reveal that inflammatory markers can remain elevated in tendinopathic tissue for months or even years after the initial injury. This chronic state explains why tendinopathy symptoms often fluctuate and why standard anti-inflammatory treatments may fail to provide relief. Additionally, changes in blood flow and vascular remodeling exacerbate these effects, further complicating the healing process.
The Role of Blood Vessel Changes in Tendinopathy
Vascular changes significantly impact the tendon’s blood supply, which is typically limited under normal conditions. Tendinopathy triggers abnormal blood vessel formation, known as neovascularization, which is often accompanied by nerve growth, heightening pain sensitivity.
While increased blood flow might sound beneficial for healing, the new blood vessels in tendinopathic tissue are often abnormal and fragile. These vessels are prone to bleeding, which contributes to ongoing tissue damage. Alongside this, neoneural ingrowth – the growth of new nerve fibers – occurs, making the affected areas hypersensitive to touch and movement. This explains why tendinopathic tendons often feel more painful and sensitive than healthy ones.
A key driver of these vascular changes is vascular endothelial growth factor (VEGF), which promotes both blood vessel formation and the recruitment of inflammatory cells. However, these changes disrupt the tendon’s nutrient and oxygen supply. Some areas may become hypervascularized, while others suffer from reduced blood flow, leading to localized ischemia. This uneven distribution hampers the tendon’s ability to repair itself effectively.
These vascular and nerve changes shed light on why tendinopathy symptoms often persist, even after mechanical stress is reduced. Addressing these underlying blood flow and nerve issues is essential for effective treatment and long-term relief.
New Research: Tendon Pressure and Metabolic Factors
Recent studies are shedding light on new contributors to tendinopathy, moving beyond the well-established trio of mechanical stress, inflammation, and vascular changes. These emerging insights are helping to paint a more detailed picture of the condition’s complexity.
Pressure Inside Tendons as a Disease Factor
A fresh perspective in tendon research focuses on intratendinous pressure – the internal pressure within tendons. Although still in its early stages, this research suggests that elevated internal pressure might impact tendon mechanics and surrounding tissue conditions. If confirmed, this could mean that tendinopathy isn’t just about external forces acting on the tendon but also about what’s happening inside it. This idea points to the need for treatments that address both external mechanical stress and these internal pressure dynamics, adding a new dimension to the tendinopathy framework.
Metabolic Conditions and Tendon Health
There’s also growing evidence that metabolic factors may influence tendon health. Metabolic conditions could affect tendon structure and disrupt healing processes, making them another piece of the tendinopathy puzzle. These findings emphasize the importance of considering overall systemic health when developing treatment plans for tendinopathy.

Evidence-Based Chiropractic Treatments in Oklahoma City
Understanding how mechanical stress, inflammation, and blood flow changes affect the body helps guide effective treatments. At Portland Chiropractic Group in Oklahoma City, Dr. Brett Weaver uses therapies grounded in research to target these issues, aiming to provide lasting relief for patients dealing with tendon pain and dysfunction. By focusing on the underlying causes of tendinopathy, these treatments work to break the pain cycle and promote tendon recovery.
Chiropractic Treatments for Tendinopathy
Chiropractic adjustments are a key part of treating tendinopathy. They address joint issues that create abnormal stress on tendons. By restoring proper joint mobility, these adjustments reduce strain on the tendons, allowing the healing process to start. Adjustments to both the spine and extremities help normalize joint mechanics, easing the excessive stress that can lead to tendon damage.
Graston technique focuses on inflammation and tissue remodeling. Using specialized tools, this method breaks down scar tissue and fascial restrictions while boosting blood flow to the affected areas. The controlled microtrauma it creates stimulates collagen remodeling, which is essential for tendon repair, and improves circulation.
Dry needling targets both inflammation and muscle dysfunction linked to tendinopathy. By addressing trigger points, it helps reset abnormal muscle activity that can overload tendons. This technique also increases local blood flow, alleviating pain and helping to interrupt the cycle of inflammation.
Shockwave therapy is particularly effective for addressing blood flow issues in chronic tendinopathy. Acoustic waves used during the treatment stimulate the growth of new blood vessels in areas where blood supply has been compromised, supporting the healing process.
Benefits and Limitations of Each Treatment
| Treatment | Primary Benefits | Limitations | Best Used For |
|---|---|---|---|
| Chiropractic Adjustments | Improves joint mechanics, reduces tendon stress, addresses root causes | Requires multiple sessions, less effective for advanced tissue damage | Early-stage tendinopathy or preventing recurrence |
| Graston Technique | Breaks down scar tissue, improves tissue quality, boosts blood flow | Temporary soreness, requires skilled practitioner | Chronic tendinopathy with significant tissue restrictions |
| Dry Needling | Relieves trigger points, resets muscle patterns, provides quick pain relief | Temporary soreness, not suitable for needle-averse patients | Tendinopathy with muscle involvement |
| Shockwave Therapy | Encourages blood vessel growth, supports healing, effective for chronic cases | Multiple sessions needed, not ideal for all tendon locations | Chronic tendinopathy with poor healing response |
Patient-Focused Care at Portland Chiropractic Group

Instead of relying on a generic approach, the clinic creates customized care plans tailored to each patient’s unique situation.
The clinic’s open layout allows patients to see how each treatment works and understand its purpose. This transparency helps patients actively engage in their recovery, giving them a clearer picture of how specific techniques address their tendon issues.
At Portland Chiropractic Group, every treatment is backed by research, ensuring it effectively targets the root causes of tendinopathy. Dr. Weaver combines his clinical experience with the latest studies to provide treatments that aim for long-term healing rather than just short-term relief.
Functional training is another essential component. By teaching patients better movement patterns and strengthening key muscle groups, this approach reduces the risk of tendon overload and helps prevent future issues. This proactive focus on movement and strength supports lasting recovery.
Private consultations further enhance the care process. These one-on-one discussions give Dr. Weaver insight into not only the physical symptoms but also how tendinopathy impacts the patient’s daily life, work, and hobbies. This comprehensive understanding allows for treatment plans that address both the biological aspects of tendinopathy and the practical challenges patients face during recovery.
Future Research and Clinical Applications
Recent work by Gehwolf and colleagues sheds light on the intricate relationship between mechanical stress, inflammation, and vascular changes in sustaining tendinopathy. This deeper understanding is paving the way for more comprehensive treatment strategies. These findings expand on the established tendinopathic loop, creating opportunities for developing more holistic treatment protocols.
Combining Multiple Treatment Approaches
The tendinopathic loop explains why relying on a single treatment method often falls short. Since mechanical stress, inflammation, and vascular changes are tightly connected, addressing only one aspect leaves the cycle intact. New research supports a multi-faceted approach, combining treatments that target these interconnected factors. By tackling mechanical, inflammatory, and vascular issues together, integrated protocols may offer better outcomes.
Current Research and New Therapies
Emerging studies are now exploring additional factors that may influence tendinopathy, such as intratendinous pressure and metabolic health. Elevated internal pressure can restrict blood flow, exacerbating mechanical stress on the tendon. Meanwhile, metabolic factors are gaining attention as potential contributors to tendon health. These insights suggest that future treatments might include strategies to manage metabolic health and relieve internal tendon pressure, broadening the scope of therapeutic options.
Key Takeaways for Patients and Providers
Managing tendinopathy effectively requires early and consistent intervention. Because mechanical, inflammatory, and vascular factors are interconnected, recovery often takes time and patience. Acting early can help disrupt the tendinopathic loop, making treatment less complex in the long run.
For healthcare providers, these findings highlight the need for a thorough and comprehensive evaluation that goes beyond the site of pain. Addressing only the symptoms is less effective than considering the full range of factors contributing to the condition. By tailoring treatment plans to the individual needs of each patient, providers can improve outcomes. As research progresses, personalized approaches may not only enhance recovery but also make better use of healthcare resources.
FAQs
How can chiropractic techniques like the Graston technique and dry needling help treat tendinopathy?
Chiropractic approaches like the Graston technique and dry needling can be valuable in managing tendinopathy. These methods focus on treating the affected soft tissues to ease pain, improve blood flow, and minimize scar tissue buildup.
The Graston technique involves the use of specialized tools to break down adhesions and scar tissue, which can enhance mobility and encourage tissue healing. Meanwhile, dry needling uses thin needles inserted into trigger points or tight muscle areas to release tension, activate the body’s natural repair mechanisms, and promote recovery.
By addressing the underlying issues of tendinopathy, these techniques work together to reduce discomfort, restore function, and support healthier tendons over time.
How does intratendinous pressure contribute to tendinopathy, and what are the treatment options?
Intratendinous pressure contributes heavily to tendinopathy by placing extra stress on tendon tissues, limiting blood flow, and sparking degenerative changes. These issues can result in pain, reduced function, and slower healing.
Treatment strategies aim to lower this pressure and support tendon health. Popular methods include eccentric exercises, which help build tendon strength, and manual therapy, designed to improve mobility and circulation. In more severe cases, surgical options may be considered to ease the pressure and restore proper blood flow. Addressing the issue early with a personalized treatment plan is critical for a smoother recovery.
Why don’t standard anti-inflammatory treatments always work for tendinopathy, and what other options are available?
Tendinopathy is a tricky condition to treat because it’s not just about inflammation. While anti-inflammatory treatments might work for some issues, they often fall short here. That’s because tendinopathy involves degenerative changes, a disorganized collagen structure, and altered blood flow – problems that simple anti-inflammatory medications can’t solve. In fact, inflammation in these cases is usually minimal or paired with tissue degeneration, making traditional treatments less effective.
To tackle tendinopathy more effectively, alternative methods aim to address its root causes. These include physical therapy to ease mechanical stress, regenerative medicine to promote tissue repair, and treatments that focus on improving blood flow and metabolic factors. By targeting the complex processes behind tendinopathy, these approaches can offer more thorough and lasting relief.
