Dynamic postural stability is an important measurement that is used in valuable clinical assessments, such as evaluating risk factors for injury or determining the progress of neuromuscular rehabilitation. It is commonly measured during jump landing tasks. Currently, the tasks used to measure dynamic postural stability are only conducted in uniplanar directions which fail to replicate the athletic environment. A single-leg hop stabilization task that incorporates a rotational component of the body would be more challenging and more closely resemble mechanisms of injury, particularly to the anterior cruciate ligament (ACL). Therefore, the goal of this study was to develop a test of dynamic postural stability that includes a rotational component and measure its reliability and precision.
The task was performed by fourteen college club and intramural athletes. Each subject performed two test sessions, with thirty minutes in between. In each session, five trials in both rotation directions were collected for each subject. To determine intersession reliability, the intraclass correlation (ICC 2,k and 2,1) and the standard error of measurement (SEM) were calculated for the DPSI scores between sessions. For rotation medially, the ICC (2,k) was 0.885 and the SEM was 0.086. For rotation laterally, the ICC (2,k) was 0.926 and the SEM was 0.139. These results support that the DPSI, assessed using a rotational jump landing task, is a reliable and precise measurement that is acceptable to use in future research.
