Myofascial trigger points in dogs: A comprehensive examination

Introduction to myofascial trigger points in dogs

Myofascial trigger points (MTPs) are changes in the muscles that can cause pain and dysfunction. In dogs, muscles make up a large proportion of body mass (44-57 %), which is why MTPs are particularly important in this species. However, MTPs are still poorly understood and recognized in veterinary medicine.

Causes of myofascial trigger points in dogs

The exact origin of MTPs is not yet fully understood. One possible cause is the so-called "integrated trigger point hypothesis," which describes MTPs as knots of contracted and thickened muscle fibers. These changes can be triggered by various factors:

• Muscle overload
• Traumatic injuries
• Chronic postural problems
• Metabolic disorders
• Stress and anxiety

Symptoms and diagnosis of myofascial trigger points

Dogs with MTPs can exhibit various symptoms, including:

• Local pain
• Restriction of mobility
• Muscle tension
• Changes in behavior, e.g., restlessness or aggression
• General weakness

The diagnosis of muscular trigger points (MTPs) is usually made through a careful clinical examination and palpation of the affected muscles. Identifying the trigger points can help to find the cause of the pain and develop targeted treatment approaches.

Where are myofascial trigger points in dogs?

Myofascial trigger points (MTPs) can occur in various muscles and body regions in dogs. The exact location of MTPs is individual and depends on various factors, such as the dog's physical activity, possible injuries, or postural problems. Some commonly affected muscles and areas in dogs are:

1. Neck and shoulder area: In dogs, MTPs can occur here due to stress, poor posture or overexertion, leading to pain or restricted movement.
2. Back muscles: The muscles along the spine, in particular, can be affected. Pain and tension in this area can impair the dog's mobility and even lead to behavioral changes.
3. Hind legs: In the thigh muscles, such as the quadriceps, muscular and transverse joint (MTP) trigger points can occur in dogs that frequently run or jump. These trigger points can cause pain and difficulty walking or climbing stairs.
4. Forelegs: The muscles in the foreleg, such as the triceps, can also be affected by MTPs. Pain in this area can lead to lameness or reduced weight-bearing capacity of the forelegs.
5. Hip and pelvic area: MTPs in the hip muscles or in the pelvic area can cause pain and restricted movement, especially when standing up, lying down or jumping.

It is important to note that MTPs are not limited to the areas mentioned above and can occur in various muscles and body regions in dogs. Accurate localization and diagnosis of MTPs should be performed by an experienced veterinarian or therapist.

Treatment options for myofascial trigger points in dogs

There are several treatment options for MTPs in dogs, including:

1. Manual therapy: Targeted massage techniques can loosen and relax the trigger points.
2. Physiotherapy: Exercises and movement therapy can help strengthen muscles and relieve tension.
3. Acupuncture: The targeted stimulation of acupuncture points can relieve pain and support the healing process.
4. Drug therapy: Anti-inflammatory and pain-relieving drugs can be used to alleviate the symptoms.
5. Trigger point injection: Injecting local anesthetics or anti-inflammatory drugs directly into the trigger points can reduce pain and relax the muscles.

How can Laser therapy Help with MTPs?

Laser therapy, also known as photobiomodulation or Low-level laser therapy Low-level laser therapy (LLLT) is known to be helpful in the treatment of myofascial trigger points (MTPs) in dogs. It involves directing light energy in the form of non-invasive, low-dose laser beams onto the affected muscle areas. The light energy penetrates the tissue and stimulates biochemical processes there, which can have various positive effects:

1. Pain relief: Laser therapy can promote the release of endorphins (the body's own painkillers) and desensitize pain receptors. This can reduce the perception of pain in dogs with MTPs.
2. Anti-inflammatory action: By stimulating blood flow and reducing inflammatory mediators, laser therapy can reduce inflammatory processes that are often associated with MTPs.
3. Muscle relaxation: The heat generated and increased blood flow during laser therapy can help to release muscle tension and improve tissue elasticity. This can reduce hardening in MTPs and improve the dog's mobility.
4. Accelerating healing: Laser therapy can stimulate cell regeneration and metabolism in the treated tissue. This can accelerate the healing of MTPs and promote the dog's overall well-being.

It is important to emphasize that laser therapy for MTPs is generally used as a complementary therapy and often in combination with other treatment approaches, such as manual therapy, physiotherapy, or medication. The optimal therapy should be individually tailored to the dog and determined in consultation with an experienced veterinarian or therapist.

Prevention of myofascial trigger points in dogs

To reduce the risk of developing MTPs / Myofascial trigger points in dogs To reduce this, the following measures should be observed:

• Regular exercise and physical activity
• Balanced diet and weight control

• Stress reduction through appropriate environment and activities
• Early detection and treatment of injuries or illnesses
• Regular check-ups at the veterinarian
• Professional support from animal physiotherapists or animal osteopaths if needed.

The role of pet owners and caretakers

Pet owners and caretakers play a crucial role in identifying and treating myofascial trigger points (MTPs) in dogs. They should be vigilant for potential signs and symptoms of MTPs, such as localized pain, restricted movement, behavioral changes, or general weakness. If MTPs are suspected, a veterinarian or a specialized therapist should be consulted.

It is also important that pet owners and caretakers are informed about MTPs and know what preventative measures they can take to reduce the risk of their dogs developing MTPs.

Interdisciplinary collaboration in the treatment of myofascial trigger points in dogs / MTPs in dogs

Treating myofascial trigger points in dogs often requires interdisciplinary collaboration among various specialists to ensure optimal care and recovery. These include veterinarians, animal physiotherapists, animal osteopaths, animal acupuncturists, and animal behavior therapists.

The collaboration of these experts enables a holistic approach to the treatment of MTPs, taking into account all relevant factors, such as the dog's physical, psychological, and emotional needs. This can help accelerate recovery, alleviate pain more effectively, and reduce the risk of relapse.

The importance of education and training on myofascial trigger points in dogs

Since myofascial trigger points in dogs are still relatively unknown in veterinary medicine, education and training for veterinarians and other professionals are of great importance. Targeted training and continuing education courses allow veterinarians and therapists to familiarize themselves with the latest findings and therapeutic approaches and expand their expertise in managing myofascial trigger points in dogs.

Pet owners and caretakers should also learn about myofascial trigger points and how to help their dogs with them. This information can be provided through events, brochures, online resources, or training courses.

Advances in technology for the diagnosis and treatment of myofascial trigger points (MTPs) in dogs

In recent years, technological advances have also been made that can be helpful in the diagnosis and treatment of myofascial trigger points in dogs. Examples include:

• Imaging techniques such as ultrasound or magnetic resonance imaging (MRI) can help to better visualize MTPs and their causes.
• Electrical stimulation or laser therapy, which can be used for pain relief and muscle relaxation.
• Wearables and sensors that monitor the movement and behavior patterns of dogs and can detect possible signs of MTPs at an early stage.

Integrating these technological advances into veterinary practice can further improve and individualize the diagnosis and treatment of MTPs in dogs.
