Which assessment is most appropriate for evaluating a client's flexibility?

Goniometric measurements are specifically designed to quantify the range of motion in joints, making them the most appropriate assessment for evaluating flexibility. These measurements are taken with a goniometer, a tool that accurately assesses the angle of joint movement. By determining the degrees of angle through which a joint can move, clinicians can objectively assess flexibility and identify limitations or asymmetries.

This method provides precise data that can be used to track progress over time or determine the effectiveness of interventions aimed at improving flexibility. It's essential in practice because flexibility can vary significantly between individuals and throughout the body.

In contrast, dynamic stretching exercises primarily focus on preparing the muscles for activity through controlled movements, rather than assessing flexibility. Static stretching holds can improve flexibility when performed regularly but do not serve as a measurement tool. Functional movement screenings assess overall movement patterns and can give insight into flexibility issues, but they are not as precise for measuring the actual range of motion at specific joints. Therefore, goniometric measurements are the best choice for a focused evaluation of flexibility.
