What common features characterize postural LBP/Pelvic Girdle Pain?

Postural low back pain (LBP) and pelvic girdle pain are often associated with muscle imbalances and gait abnormalities. This relationship arises because the body's biomechanics are altered due to compensation mechanisms, either from overuse of specific muscle groups or underuse of others. When particular muscles are overactive or tight, while their antagonistic or stabilizing muscles are weak or inhibited, this can lead to altered movement patterns. Such imbalances often manifest as gait abnormalities where individuals might change their walking pattern to accommodate or relieve discomfort, ultimately perpetuating pain and dysfunction.

In contrast, increased flexibility and strength would typically suggest a balanced musculoskeletal system, which is not characteristic of those suffering from postural pain. Similarly, consistent pain without muscle imbalances does not accurately depict the underlying issues since muscle imbalances are often a core problem leading to pain. Lastly, normal lordosis and kyphosis imply that the spinal curvatures are intact and not contributing to postural issues, which is generally not the case in individuals with postural LBP or pelvic girdle pain. Hence, the presence of muscle imbalances and gait abnormalities is a primary feature of this condition.
