Activation of trigger points may be caused by a number of factors, including acute or chronic muscle overload, activation by other trigger points (key/satellite, primary/secondary), disease, psychological distress (via systemic inflammation), homeostatic imbalances, direct trauma to the region, collision trauma (such as a car crash which stresses many muscles and causes instant trigger points ...
However, a mental health professional might use the DSM-5 to identify related conditions that could be influenced by chronic stress, such as: Post-traumatic stress disorder ( PTSD ) Adjustment ...
Symptoms of a myofascial trigger point include: focal point tenderness, reproduction of pain upon trigger point palpation, hardening of the muscle upon trigger point palpation, pseudo-weakness of the involved muscle, referred pain, and limited range of motion following approximately 5 seconds of sustained trigger point pressure. [2] The cause ...
The Golgi tendon reflex operates as a protective feedback mechanism to control the tension of an active muscle by causing relaxation before the tendon tension becomes high enough to cause damage. [7] First, as a load is placed on the muscle, the afferent neuron from the Golgi tendon organ fires into the central nervous system.
Stress management encompasses techniques intended to equip a person with effective coping mechanisms for dealing with psychological stress, with stress defined as a person's physiological response to an internal or external stimulus that triggers the fight-or-flight response. Stress management is effective when a person uses strategies to cope ...
Chronic stress reduces resistance of infection and inflammation, and might even cause the immune system to attack itself. [27] Stress responses can cause atrophy of muscles and increases in blood pressure. [28] When the stress is chronic, it will lead to sustained elevated blood pressure, impairing the heart functions. [7]
Because muscle spindles and tendon organs exhibit burst-like activity in response to rapid stretch, they play a vital role in reflexive perturbation responses. In a simulation study, it has been shown that the controllability of a limb in response to a perturbation is significantly increased when utilizing muscle spindle and tendon organ ...
