Trigger Point Injections

Physiological Responses to Trigger Point Injections

Local Responses

• Pain relief: Trigger point injections can provide immediate pain relief by releasing tension in the affected muscle.
• Muscle relaxation: The injection can cause a decrease in muscle tone, leading to relaxation of the affected muscle.
• Increased range of motion: Trigger point injections can increase the range of motion in the affected joint or muscle.

Systemic Responses

• Release of tension: Trigger point injections can lead to a systemic release of tension, affecting multiple muscle groups.
• Endorphin release: The injection can stimulate the release of endorphins, the body's natural painkillers.
• Anti-inflammatory effects: Some injectable substances, such as corticosteroids, can have anti-inflammatory effects, reducing swelling and inflammation.

Neurological Responses

• Neurotransmitter modulation: Trigger point injections can affect the release of neurotransmitters, such as substance P and calcitonin gene-related peptide, which are involved in pain processing.
• Central nervous system modulation: The injection can influence the central nervous system's processing of pain, leading to a decrease in pain perception.

Other Physiological Responses

• Autonomic nervous system response: Trigger point injections can affect the autonomic nervous system, leading to changes in heart rate, blood pressure, and other autonomic functions.
• Hormonal responses: Some injectable substances, such as corticosteroids, can have effects on the hormonal system, including the release of cortisol and other hormones.

Physiological Responses to Trigger Point Injections

Local Responses

• Immediate pain relief is achieved by releasing tension in the affected muscle
• Muscle tone decreases, leading to relaxation of the affected muscle
• Range of motion in the affected joint or muscle increases

Systemic Responses

• Trigger point injections lead to a systemic release of tension, affecting multiple muscle groups
• Endorphins, the body's natural painkillers, are stimulated and released
• Anti-inflammatory effects, such as reducing swelling and inflammation, can be achieved with injectable substances like corticosteroids

Neurological Responses

• Neurotransmitters, such as substance P and calcitonin gene-related peptide, involved in pain processing are modulated
• The central nervous system's processing of pain is influenced, leading to a decrease in pain perception

Other Physiological Responses

• The autonomic nervous system is affected, leading to changes in heart rate, blood pressure, and other autonomic functions
• Hormonal responses, such as the release of cortisol and other hormones, can occur with certain injectable substances like corticosteroids
