Joint angles of lower limb gait and sEMG signals

During the performance of five lower limb movements including level walking, ascending and descending stairs, and ascending and descending a slope (with a slope angle of 10°), the sEMG data of eight lower limb muscles—Rectus Femoris (RF), Vastus Lateralis (VL), Vastus Medialis (VM), Biceps Femoris (BF), Semitendinosus (ST), Tibialis Anterior (TA), Medial Gastrocnemius (MG), and Soleus (SOL)—and synchronized knee joint angle data were recorded. The sEMG signals of eight muscle channels on one leg were recorded using sEMG sensors at a sampling frequency of 1000 Hz. The angle data were collected using the VICON optical motion capture system, also at a sampling frequency of 1000 Hz. The movement duration for each subject was approximately 11 seconds.
