Outcome Measures
Primary Outcomes (5)
Kinematics of lower-limb during landing phase
The data will be collected by VICON motion capture system, include hip, knee and ankle joint angle in three plane. (frontal plane, sagittal plane and transverse plane)
from taking off to landing, about 5 seconds.
Kinetics of knee joint during landing phase
The data will be collected by VICON motion capture system and calculated by inverse dynamics, include knee flexion/extension moment, abduction/adduction moment, internal/external rotation moment.
from taking off to landing, about 5 seconds.
Muscle onset time of lower-limb muscles during landing phase
The data will be collected by wireless electromyography, include rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinosus.
from taking off to landing, about 5 seconds.
Muscle activation of lower-limb muscles during landing phase
The data will be collected by wireless electromyography, include rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinosus, anterior tibialis, medial gastrocnemius
from taking off to landing, about 5 seconds.
Muscle activation-Hamstring and Quadriceps ratio (H/Q ratio) during landing phase
The data will use the amount of hamstring and quadriceps muscle activation to calculate H/Q ratio.
from taking off to landing, about 5 seconds.
Eligibility Criteria
Age between 20-50 years old
You may qualify if:
- Only one leg has operation of ACL reconstruction
- At least 1 year after ACLR or have been back to sports
- Exercise in sports regularly.
You may not qualify if:
- Other operation of lower extremity exclude ACLR
- Any diseases or poor condition that will affect jumping or deterioration after jumping.
