Outcomes
Primary Outcomes
Lower extremities kinetic
Time Frame: 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed
Three dimensional motion data were collected using a Vicon camera system during walking. Using motion capture system data to calculate the hip, knee internal/external rotation moment and ankle inversion/eversion moment via inverse dynamics method.
Lower extremities kinematic
Time Frame: 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed
Lower limbs alignment, including hip, knee and ankle joints. Using motion capture system data to calculate the joint angles.
Peak and average amplitude during stance phase
Time Frame: 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed
EMG data were collected using a Delsys, and Biopac EMG system during walking. Tibialis anterior/Peroneal longus/Abductor hallucis longus muscle activity were measured by electromyography (EMG).
Secondary Outcomes
- Peak and average amplitude during stance phase(10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed)
- Time of completed fatigue protocols(1 minutes after fatigue protocol completed)
- Inter-joint contact force(10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed)
- Lower extremities kinetic(10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed)
- Lower extremities kinematic(10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed)
