case_images: Use-case example of weekly changes in biomechanical principal component scores and self-reported pain in a collegiate female basketball athlete across the 2022-2023 competitive season. Specifically, on-court impact load and self-reported pain levels peaked before the detection of statistically significant alterations in on-court asymmetry. To highlight the on-court asymmetry-specific minimum detectable change (MDC), upper and lower bounds are depicted for red-flagging biomechanical fluctuations above and beyond the measurement error of the system. The MDC statistics are derived based on five-weeks of preseason training and normative biomechanical patterns exhibited at the cohort level, with this MDC value applied (+-) to the average value that this subject displayed across the same timeframe to calculate individualized bounds by which their on-court asymmetry fluctuated from their normative patterns. It is important to note that this figure underrepresents the amount of data that was collected per participant over the two-year study period, as (i) only data from the 2022-2023 season are presented, as the first season (2021-2022) was only used to train the PCA model, and (ii) only weeks in which all three forms of data (i.e., on-court biomechanics, CMJ biomechanics, and psychological state) were concurrently collected are visually represented for simplicity sake and interpretability.

case_images: The first example identified fluctuations in on-court asymmetry patterns and concurrent or prior changes in perceived pain and on-court impact load (Figure 1). In the first example (Figure 1), it is apparent that this female athlete showed fluctuations beyond their typical on-court asymmetry patterns near the end of the 2022-2023 competitive basketball season.
case_images: Use-case example of weekly changes in biomechanical principal component scores and self-reported pain in a collegiate female basketball athlete across the 2022-2023 competitive season. Specifically, jump asymmetry-specific minimum detectable change (MDC) upper and lower bounds are depicted for red-flagging biomechanical fluctuations above and beyond the measurement error of the system, which were paralleled, to some extent, by seasonal changes in self-reported levels of pain. The MDC statistics are derived based on five weeks of preseason training and normative biomechanical patterns exhibited at the cohort level, with this MDC value applied (+-) to the average value that this subject displayed across the same timeframe to calculate individualized bounds by which their jump asymmetry fluctuated from their normative patterns. However, this "unperturbed" baseline period was confounded by high levels of self-reported pain in this athlete, suggesting that our normative biomechanical patterns might not necessarily indicate what we would expect in this athlete. It is important to note that this figure underrepresents the amount of data that was collected per participant over the two-year study period, as (i) only data from the 2022-2023 season are presented, as the first season (2021-2022) was only used to train the PCA model and (ii) only weeks in which all three forms of data (i.e., on-court biomechanics, CMJ biomechanics, and psychological state) were concurrently collected are visually represented for simplicity sake and interpretability.

case_images: In contrast, the second example focuses on identifying alterations in jump asymmetry patterns while highlighting the potential difficulty in establishing normative biomechanical patterns without contextualizing them with other facets of health, such as self-reported pain levels (Figure 2). The second case example (Figure 2) highlighted seasonal fluctuations (i) during the end of the preseason in October 2022 and (ii) after the regular season just before collegiate-level playoffs in February 2023 that exceeded the MDC threshold in normative jump asymmetry patterns that we were able to red-flag for further examination. Interestingly, the on-court asymmetry and self-reported pain from this athlete, as seen in orange and black, respectively, in Figure 2, displayed similar and somewhat paralleled fluctuations to jump asymmetry.
