What describes the posture of sway back?

1. Straightening of the lower thoracic spine and forward head position

2. Exaggerated lumbar lordosis and posterior pelvic tilt

3. Rounding of the thoracic spine and hyperextended knee

4. Flat thoracic spine with anterior pelvic tilt

The correct answer is: Rounding of the thoracic spine and hyperextended knee

The definition of sway back posture primarily involves a unique alignment and curvature of the spine. In sway back posture, there is a noticeable rounding of the thoracic spine, which is often accompanied by hyperextension of the knees. This posture displaces the pelvis and affects the overall alignment of the back and pelvis, leading to an appearance where the upper body may be positioned behind the hips. This description aptly fits the features of sway back. The rounding of the thoracic spine indicates a lack of extension in this region, while the hyperextended knees suggest increased reliance on the knee joints rather than proper muscular support from the hips and core. This misalignment is common in individuals with muscle imbalances and can result in discomfort or pain over time. The other options describe different postural abnormalities: - One option mentions changes in the lower thoracic spine and forward head position, which don't characterize sway back. - Another option talks about exaggerated lumbar lordosis and posterior pelvic tilt, which is more representative of a flattened lower back rather than the sway back characteristic. - The fourth option describes a flat thoracic spine with anterior pelvic tilt, which indicates a different postural issue altogether. Understanding these attributes helps in recognizing sway back posture and addressing its implications for exercise and rehabilitation effectively.
