Which movement should be avoided if a client presents with acute lower back pain?

When a client is experiencing acute lower back pain, it is important to consider which movements could exacerbate their condition. Sitting forward bends are especially problematic in this scenario because they often place significant strain on the lumbar spine. This movement requires flexing forward at the hips while maintaining some degree of spinal flexion, which can increase pressure on the discs and potentially irritate already sensitive tissues in the lower back. This added strain can exacerbate pain and hinder the healing process.

In contrast, other movements such as bridging, plank, and hinging at the hips can be performed with more control and often allow for spinal stabilization, which can be beneficial. Therefore, avoiding sitting forward bends is paramount in managing acute lower back pain effectively and encouraging recovery.
