Yoga Validation Study
Previous studies have collected lower limb biomechanical data on yoga using marker-based motion capture, which is considered the gold standard for human motion analysis. However, wearing markers while performing yoga poses may be uncomfortable for participants, and placing markers is time-consuming and can vary between researchers. Markerless motion capture promotes natural movement more than traditional marker-based motion capture, but it has not yet been proven effective in collecting data on yoga. Thus, the objective of this study is to compare biomechanics data collected by marker-based and markerless systems during yoga in healthy adults. These findings will be used to design the experimental protocol of the post-THA study described below.
Hip motion during yoga in individuals post-total hip arthroplasty
Currently, no uniform clinical guidelines exist for returning to yoga following hip surgery. While we have previously quantified hip angles during yoga poses thought to stress the hip in healthy individuals, it is unclear whether patients who have undergone total hip arthroplasty (THA) and regularly practice yoga achieve similar joint angles during these poses. Thus, the overall objective of this proposal is to quantify lower limb joint angles during these poses in individuals post-THA who regularly practice yoga and age- and sex-matched controls without THA. The secondary objective is to investigate factors that may affect hip motion post-THA (e.g., pain, implant design).
