非外傷的情況下，軟組織的痠痛，通常和疲勞有關。不同於休閒峙的運動，在有目的及壓力下的勞動中，反覆的動作很容易產生疲勞，即使在不動的情況下，爲了長時間維持固定的姿勢，對於相關部位的肌肉群，也會產生一定的負擔。當超過自身的負荷閾值或恢復能力後，則警告性的痠痛便會出現，若不加以處理，便容易形成軟組織的慢性傷害。人體在做動作時，通常不會只使用到單一束肌肉，而是某相關部位的肌肉群。以手臂平舉爲例，可視爲手臂作功，從拳頭的角度來看，是單一向量移動所得的功；但就肌肉而言，卻不是單一肌肉束所致，而是複數的肌肉群，由數個合力矩作功總和的結果。當痠痛對手臂造成活動阻礙時，即活動範圍角度和出力大小受到限制或減少，從能量守恆的角度來看，對手臂肌肉群而言，受到痠痛限制的部分，即爲減少的作功數值，此數值可視爲協同肌群上數個力矩作功所減少的總和。隱痛點療法，就是把某部位出力作功所減少部分的總不日，分散於協同肌群中復數個分力矩，並將關節看作是力矩的起點，採取跨過關節的肌肉上，在類似潛伏性肌筋膜激痛點症狀的位置，來分散並舒緩疼痛的操作手法。

Non-traumatic soft tissue tenderness and pain often result from fatigue. Different from recreational sports, repetitive movements during exercise often result in fatigue. In order to maintain certain position for a long period of time, it creates burden to relative muscle groups. When the threshold is crossed, warning tenderness will appear. If the tenderness is not dealt with in time, it will result in chronic damage to soft tissues. When our body performs certain movement, a group of muscles instead of a single muscle bundle will be involved. Take shoulder abduction as an example, it is the work performed by the arm, a single vector started from the fist. It is a combined work done by several muscle groups. When the tenderness case limitation of movement, the limitation or reduction of the range of motion and muscle strength, it is the work that's not performed by the muscle groups of the arm. The value of the work is the combination of the reduction of work of synergistic muscle groups. The tender point treatment is to allocate the reduced work to other sub-torques within synergistic muscle groups, and consider the joint as the initial point of the torque, and apply manipulation on latent myofascial trigger point on muscles that cross the joint to alleviate pain.
