When a client with fused vertebrae is performing Short Box Series on the Ladder Barrel, which variation should they omit?

In the context of the Short Box Series on the Ladder Barrel, clients with fused vertebrae should omit the round back with rotation variation. This is because clients with fused vertebrae often have restricted spinal mobility, particularly in the thoracic and lumbar regions, which makes rotational movements potentially hazardous. Rotating the spine can place undue stress on the fused vertebrae, leading to discomfort or injury.

The other variations, such as side stretch, flat back, and forward reach, primarily focus on flexion and extension or lateral bending, which can be adapted to accommodate varying degrees of spinal stability. These movements can still be performed safely without the rotational component, allowing the client to engage in the exercise while minimizing the risk of strain. Thus, omitting the round back with rotation keeps the workout effective while ensuring the safety and comfort of the individual with fused vertebrae.
