LSTM model's performance was evaluated using CC across various output window sizes of 5, 10, and 15 time steps. Input window sizes ranged from 10 to 100 time steps, including 10, 15, 20, 30, 40, 50, 70, and 100. The bar chart displays the average performance metrics for the bilateral elbow and knee joints, highlighting the impact of different output window sizes
