Which tests can best evaluate trunk rotation and separation?

The most effective way to evaluate trunk rotation and separation involves specific tests designed to directly assess the movement capabilities and flexibility of the trunk. In this case, trunk rotation tests focus on the ability of the thoracic spine to rotate, which is crucial for a proper body-swing connection in activities like golf. Additionally, lat tests can provide insights into how well the latissimus dorsi muscles, which are integral to trunk rotation, function and contribute to overall body mechanics. This combination of trunk rotation and lat tests ensures a comprehensive assessment of how well the upper body can separate from the lower body during dynamic movements, thus highlighting their importance in the context of sports such as golf.

In contrast, options that include assessments like forearm planks and wall sits primarily measure stability and endurance rather than dynamic rotational capability. Similarly, hip joint range of motion assessments focus more on lower body mobility, while central nervous system coordination tests evaluate broader movement patterns rather than isolating trunk rotation and separation specifically.
