Muscle guarding is a physical response to pain, which emanates from the brain. It is a protective mechanism that causes the muscles around an injured area to tighten up and restrict movement to avoid further pain or injury. While muscle guarding can be beneficial in the short term, if left untreated, it may become part of the problem, leading to a vicious cycle of pain and anxiety. This can cause emotional distress and limit recovery, making it an area of interest for researchers.

What You'll Learn

Muscle guarding is a response to pain
Muscle guarding is a physical response to pain. It is a protective mechanism that is built into us, causing the muscles around an injured area to tighten up and restrict movement to avoid further pain or injury. This is often beneficial in the short term, allowing the body to heal. However, if left untreated, muscle guarding can become part of the problem, impeding recovery and worsening pain.
When an injury occurs, the body's first alarm is pain. The same nerves that signal pain also indicate that an injury has happened. The brain then seeks to protect the injured area by subconsciously directing the surrounding muscles to tense up, spasm, or lock. This is muscle guarding. It is an attempt by the brain to prevent further damage to injured tissues by ''splinting' the area with a spasm, effectively reducing painful joint movements. The brain acts to protect the body, and muscle guarding is its way of wrapping you up in bubble wrap.
While muscle guarding can be a good thing in the short term, protecting us from further injury, it can cause problems if it continues for too long. The restricted movement caused by muscle guarding can lead to muscle weakness and atrophy, as the muscles become weak and shrink in size from lack of use. This can result in a decreased function, limiting our lifestyles as we avoid using the injured area due to stiffness and soreness.
The continued pain, guarding, and loss of function associated with prolonged muscle guarding can lead to emotional and mental stress, including anger, frustration, depression, and helplessness. These negative emotions can increase stress and tension in the body, lower our motivation, and reinforce the pain cycle. The brain becomes hyper-aware, and rewired neural pathways cause it to infer pain even when none is present, leading to anxiety and chronic muscle guarding.
To break the pain cycle caused by muscle guarding, the focus should be on reducing or minimising the source of pain. Chiropractic adjustments and specific exercise therapy can help stop muscle guarding and restore normal function. Massage, heat, cupping, dry needling, and manual massage are also effective treatments for muscle guarding.

It can be triggered by injury or surgery
Muscle guarding is a physical response to pain, often triggered by injury or surgery. It is a protective mechanism that causes the muscles around the injured area to tighten up and restrict movement, acting as a splint to prevent further injury. While this can be beneficial in the short term, protracted muscle guarding can prolong pain and impede the recovery process.
When an injury occurs, the body's first response is to signal pain. The same nerves that signal pain also indicate that an injury has taken place. As a result, the body's protective response is to cause the muscles around the injured area to contract and guard the injury. This is known as muscle guarding.
In the case of injury or surgery, muscle guarding can be particularly prominent. For example, patients who undergo knee replacement surgery may experience post-surgical pain, leading to extreme muscle guarding that prevents them from performing their prescribed rehabilitative exercises. Similarly, muscle guarding can occur after a broken ankle, with patients tensing up even at the thought of the injured area being touched.
The brain plays a crucial role in muscle guarding. It receives sensory information from the injured area, including input from joint position sensors (proprioceptors), stretch receptors, and pressure receptors. The brain then interprets this information and categorizes it as pain. As a protective measure, the brain may instruct the muscles surrounding the injured area to lock or not function, defending the body against additional pain or injury.
While muscle guarding can be beneficial in the acute phase of healing, the chronic phase can lead to frustration for both clinicians and patients. Prolonged muscle guarding can worsen pain and impede recovery. This is because, over time, the guarded area of the body may become weak, fatigued, and atrophied due to disuse of the surrounding musculature.

It can lead to a vicious cycle of pain
Muscle guarding is a physical response to pain. It is a protective mechanism that causes the muscles around an injured area to tighten up and restrict movement, thereby avoiding further pain or injury. While this can be beneficial in the short term, protracted muscle guarding can lead to a vicious cycle of pain.
As muscle guarding restricts movement, it can lead to muscle weakness and atrophy over time. The affected area becomes weak and fatigued due to disuse, and the surrounding musculature shrinks in size. This decreased function further limits mobility and can lead to a downward spiral of pain and disability. The body's normal response to an injury should be to restore function and prevent the pain cycle from continuing. However, muscle guarding can impede recovery and worsen pain, prolonging the healing process.
The brain plays a significant role in muscle guarding. It receives sensory information about an injury and interprets it as pain. The brain then seeks to protect the injured area by subconsciously directing the surrounding muscles to lock or not function, triggering a muscle spasm. While this protective response is intended to prevent further damage, it can lead to chronic muscle guarding if left untreated. The brain becomes hyper-aware, and rewired neural pathways cause it to infer pain even when none is present, perpetuating the cycle of pain.
Anxiety and emotional stress also play a role in chronic muscle guarding. The continued pain, guarding, and loss of function can lead to anger, frustration, depression, and helplessness. These emotional and mental stresses increase stress and tension in the body, lower motivation, and contribute to the continuation of the pain cycle. Additionally, anxiety about moving the injured area can put muscles on even higher alert, exacerbating the problem.
To break the vicious cycle of pain, the focus should be on reducing or minimising the source of pain. Treatments such as physical therapy, chiropractic adjustments, heat, cupping, dry needling, and manual massage can help alleviate pain and muscle guarding. Addressing anxiety and emotional stressors associated with the injury may also be crucial in breaking the cycle.

Anxiety may play a role in chronic muscle guarding
Muscle guarding is a physical response to pain. It is the body's way of protecting itself from further injury. When an injury occurs, the nerves that signal pain also indicate that an injury has happened. The body's natural response is to cause the muscles around the injured area to tighten up and restrict movement to avoid pain. This is known as muscle guarding.
While muscle guarding can be beneficial in the short term, allowing the injured area to heal, it can become detrimental if it persists for too long. This is known as the chronic phase of muscle guarding, which often frustrates both clinicians and patients. The brain stays in overdrive, impeding recovery and worsening pain. The more the muscles clench, the more the body becomes locked, leading to decreased function and restricted mobility.
Chronic muscle guarding can be challenging to break out of, as the brain becomes hyper-aware, creating new neural pathways that infer pain even when none is present. This can lead to a vicious cycle where the brain learns to be in pain and any attempt to move the injured area can lead to anxiety, further exacerbating the muscle guarding.
Research has found that anxiety may play a significant role in chronic muscle guarding. In fact, anxiety, rather than pain, may be the main determinant in its development. When faced with an injured or recovering area of the body, the brain considers various factors, including the person's emotional state. If anxiety is present, it can put the muscles on even higher alert, leading to or exacerbating muscle guarding.
Treatments that help alleviate anxiety may also help reduce chronic muscle guarding and lessen pain. Specific exercise therapy, in conjunction with chiropractic care, can be effective in breaking the cycle.

Chiropractic adjustments can help treat muscle guarding
Muscle guarding is a physical response to pain, which emanates from the brain. It is a protective mechanism that causes the muscles around an injured area to tighten up and restrict movement to avoid further pain or injury. While muscle guarding can be beneficial in the short term, if it lasts too long, the restricted mobility can lead to muscle weakness and atrophy. It can also cause emotional and mental stress, leading to a downward spiral of continued pain and increased muscle guarding.
Chiropractic adjustments can be an effective treatment option for muscle guarding. Chiropractic care focuses on treating the musculoskeletal system and alleviating symptoms of pain, muscle stiffness, and dysfunction. By performing adjustments, chiropractors can trigger a relaxation response in the muscles that were previously guarded. The quick force applied during an adjustment overrides the pain sensation by triggering different, larger nerve fibers than the pain fibers. This nerve stimulation travels to the brain, resulting in the relaxation of the previously guarded muscles.
In addition to adjustments, chiropractors may recommend exercises, stretches, and ergonomic improvements to enhance posture and mobility. They may also suggest icing or heat therapy, electrical muscle stimulation, and techniques to manage stress and relax muscles. These complementary treatments can help break the cycle of pain and muscle guarding, improving overall recovery.
Chiropractic adjustments are a common alternative treatment option, especially for those seeking a non-invasive approach that does not involve prescription medication. A screening before the adjustment ensures that a patient is a suitable candidate for chiropractic care. If not, chiropractors can refer patients to other healthcare providers to ensure they receive the most appropriate treatment for their condition.
