Primary |
Stride Length Change |
Kinovea 0.8.15 software was used for gait video calibration to analyze and calculate the stride length, which is the longitudinal linear distance between two consecutive heel touches on the same side of the foot during walking. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |
|
Primary |
Step Length Change |
Kinovea 0.8.15 software was used to calibrate the gait video to analyze and calculate the step length, which is the longitudinal linear distance between two points when the left and right heels touch the ground during walking. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |

Primary |
Stride Length Time Change |
Kinovea 0.8.15 software was used to calibrate the gait video to analyze and calculate the stride length, which is the time between two consecutive landings on the same side of the heel during walking. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |

Step Length Time Change |
Kinovea 0.8.15 software was used to calibrate the gait video to analyze and calculate the step length time, which is the time between the two points where the left and right heels touch the ground during walking. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |
|
Primary |
Single Support Phase Change |
Kinovea 0.8.15 software was used to calibrate the gait video to analyze and calculate the single support phase, which is the time between the toe of one foot leaving the ground and the foot following the ground on that side during walking. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |
|
Primary |
Oscillation Frequency Change |
Oscillation Frequency (Hz) is the intrinsic pressure of the muscle, that is, the pressure carried by the muscle itself in the relaxed state or in the absence of voluntary contraction, and represents the muscle tone. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |
|
Primary |
Mechanical Stress Relaxation Time Change |
Mechanical Stress Relaxation Time (MSRT) is the time required for the muscle to return from its deformed state to its original state after active contraction or withdrawal of external pressure. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |
|
Primary |
Creep Change |
Creep (Deborah number) is the ratio of the mechanical stress release time to the time required for the muscle to reach maximum deformation by external force, SRT and Creep represent muscle viscosity. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |
|
Primary |
Range of Motion Change |
Active and passive Range of Motion in knee flexion. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |
|
Primary |
2000 IKDC Subjective Knee Evaluation Form Change |
2000 IKDC Subjective Knee Evaluation Form is divided into three modules: knee symptoms (7 questions), motor activity (10 questions) and self-functional score (2 questions), where knee symptoms include frequency and degree of pain, stiffness, swelling, locking and instability; motor activity includes activity level, going up and down stairs, squatting, kneeling straight down, sitting and standing up with bent knees, running, jumping and landing on the affected limb, and quick starts and stops; and self-functional score includes pre-injury and current self-functional scores, graded from unable to perform daily activities (0 points) to unrestricted daily activities (10 points). The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). Follow-up was performed again one year after the end of the intervention using the IKDC score. |

Secondary |
Degree of Knee Swelling Change |
The circumference of the knee joint was measured with a soft tape to indicate the degree of swelling of the knee joint. The subject was placed in a supine position with the lower extremities in a slightly flexed and relaxed position, and the hands were placed naturally on the side of the body. The medial and lateral femoral condyles were used as the midline of the knee joint, and the circumference of the knee joint enclosed by this midline was measured and recorded with the upper edge of the soft dipstick to reflect the swelling of the knee joint. The swelling effect of the intervention was reflected by the change in the circumference of the knee before and after training, and the difference in circumference between the two sides could reflect the degree of swelling. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |
|
Secondary |
Thigh Muscle Atrophy Change |
Thigh circumference can indirectly indicate the strength of the knee flexor and extensor muscles by indirectly reflecting the cross-sectional area of the thigh muscles, so the circumference of the thigh at 10 cm above the patella was measured with a soft dermatome to reflect the muscle strength of the thigh, and the resulting atrophy index was calculated to reflect the degree of atrophy of the thigh. The time, place, and testers of the test were kept consistent. |
Each subject was tested before the first intervention training and after the sixth intervention training (on average 2-3 weeks after the first intervention). |
