![]() ![]() The use of 2D motion analysis assisted with identification of key mobility elements impacted during the single and dual task conditions. Key mobility elements were significantly affected across dual task walking conditions in persons with PD. No significant relationships were found between disease severity (HY/UPDRSm) and turn strategy. Repeated-measures MANOVA differences were observed in WTT ( p = 0.01), number of turn steps ( p = 0.03), TTS ( p < 0.001), total number of TUG steps ( p = 0.01), and total TUG time ( p = 0.01). Turn strategy was consistent across TUG tasks despite added cognitive loading. All key elements were significantly different between TUG conditions with the exception of sit-to-walk and turn strategy. Thirty-one participants with PD completed this study. Participants performed Timed Up and Go (TUG) single, dual task conditions (TUG alone, TUG motor, and TUG cognitive). 2D motion analysis application was used to quantify seven key mobility elements including: sit-to-walk (STW) (s), walking turn time (WTT) (s), number of turn steps, turn-to-sit (TTS) (s), total number of TUG steps, total TUG time and turn strategy (on-the-spot or u-shaped). To determine the impact of dual-tasking on key mobility elements during a walking task in people with PD with 2D motion analysis. Walking for people with Parkinson’s disease (PD) degrades during motor-cognitive interplay (i.e., dual task conditions). Declining gait mechanics and turning ability result in more frequent falls and an interruption of daily activities in persons with PD. ![]()
