Brief summary

This study aims to investigate the improvement effect of visual-guided balance training on the knee joint function and gait performance of patients after ACLR, and to clarify the advantages of this training program compared to conventional rehabilitation training; at the same time, by including healthy individuals as the control group, it quantifies the differences in knee joint function and gait performance between patients after ACLR and healthy individuals, to verify whether visual-guided balance training can more effectively narrow the functional gap between patients after ACLR and healthy individuals, and promote the recovery of patients' knee joint function and gait closer to the healthy level. Ultimately, it provides scientific theoretical basis and practical guidance for the optimization of the rehabilitation plan after ACLR, and helps patients achieve comprehensive and high-quality recovery.

Detailed description

In this randomized controlled clinical study, patients with primary unilateral anterior cruciate ligament rupture were included. Starting from the 5th week after surgery, in addition to the standardized rehabilitation training content, the traditional group added general balance training, and the intervention group added visual guidance balance training. The analysis was conducted through movement function tests and evaluations, with the healthy group included as the control. The impact of visual guidance balance training on the movement function and biomechanical characteristics after ACLR was explored.

Interventions

Based on the traditional standardized rehabilitation program, additional universal balance training content has been added. Starting from the 5th week after the surgery and continuing until the 14th week, three times a week for a total of 10 weeks, the training duration was one and a half hours each time.

OTHERIntervention Group

Based on the conventional standardized rehabilitation program, add the content of visual-guided balance training.Starting from the 5th week after the surgery and continuing until the 14th week, three times a week for a total of 10 weeks, the training duration was one and a half hours each time.

Inclusion criteria

for patients: 1. Age between 18 and 45 years old; 2. Body Mass Index (BMI) ranging from 18.5 kg/m² to less than 35 kg/m²; 3. First unilateral ACL rupture and reconstruction surgery performed at this hospital; 4. Autologous hamstring tendon transplantation; 5. No or only minor injury to the meniscus, posterior cruciate ligament, medial collateral ligament or lateral collateral ligament; 6. Voluntary participation in this study and signing of informed consent form.

Exclusion criteria

for patients: 1. Patients who underwent ACL reconstruction more than one year after the injury; 2. Patients with severe injuries to the posterior cruciate ligament, medial collateral ligament or lateral collateral ligament (more than grade I; grade II is partial tear, thickening and tortuosity of the ligament, partial fiber interruption, and swelling of the surrounding soft tissues; grade III is complete rupture). ; Combined with severe meniscus tear; 3. Has a history of previous knee surgery, such as meniscus repair, ligament reconstruction, joint replacement, joint cleaning, etc.; 4. Has other knee joint diseases, such as: knee osteoarthritis, knee joint tumor, rheumatoid arthritis, tuberculosis, knee joint infection or inflammatory diseases, fracture, dislocation or other bone injuries, etc.; 5. Severe heart, lung, brain diseases or liver and kidney dysfunction, and visual and cognitive impairments. Inclusion criteria for the healthy control group 1. Age 18-45 years old; 2. Body Mass Index (BMI) ≥ 18.5 kg/m2 and \< 35 kg/m2; 3. No surgical history, injury history, or chronic joint diseases of the lower extremities; 4.

Design outcomes

Primary

MeasureTime frameDescription
Vicon 3D Gait TestingPreoperative baseline; 14 weeks after the operation; 6 months after the operationThe subjects first underwent a static test, and then chose to perform tests of slow jogging, walking and single-leg balance at their own pace. Observe the three-dimensional plane joint angles(degree) of each joint in the lower limbs.
isokinetic muscle strengthPreoperative baseline;14 weeks after the operation; 6 months after the operationThis isokinetic muscle strength test selected two angular velocities: 60°/second (slow speed) and 180°/second (medium speed). Observe the relative peak torque ( N·m/kg)of the quadriceps and hamstring muscles.
Imoove Balance Training TesterPreoperative baseline; 4 weeks after the operation; 14 weeks after the operation; 6 months after the operationThe dynamic balance ability of the subjects was evaluated. The main observations included the imbalance percentage, the score of the green target, coordination, stability, distribution balance, and the total score. The score ranged from 0 to 100, with a higher score being better.

Secondary

MeasureTime frameDescription
Tampa Scale for Kinesiophobia-11Preoperative baseline; 4 weeks after the operation; 14 weeks after the operation; 6 months after the operationTSK-11 (Tampa Scale for Kinesiophobia-11, a simplified version of the Tampa Scale for Kinesiophobia) is a tool used to assess an individual's fear of movement/body activity (kinesiophobia). It consists of 11 items, with a total score ranging from 11 to 44; the scoring rule is as follows: ≤ 26 points indicate no significant kinesiophobia, while \> 26 points indicate the presence of kinesiophobia, and the higher the score, the greater the fear of movement and the more severe the avoidance tendency.
Lysholm Knee Joint Scoring ScalePreoperative baseline; 4 weeks after the operation; 14 weeks after the operation; 6 months after the operationThe Lysholm Knee Joint Scoring Scale is a tool used to evaluate the function of the knee joint and to monitor the rehabilitation process after knee joint injury or surgery. The score ranges from 0 to 100, with a higher score indicating better recovery of knee joint function. The score ranges from 0 to 100.
ACL Return to Sport after Injury scalePreoperative baseline; 4 weeks after the operation; 14 weeks after the operation; 6 months after the operationThe ACL Recovery Sport Readiness Index (ACL-RSI) is a scale used to assess the psychological readiness of patients with anterior cruciate ligament (ACL) injury/reconstruction to return to sports. This scale consists of 12 items and is scored on a scale of 0 to 100. The higher the score, the better.
International Knee Documentation Committee Knee Assessment ScalePreoperative baseline; 4 weeks after the operation; 14 weeks after the operation; 6 months after the operationThe International Knee Documentation Committee Knee Assessment Scale is a comprehensive tool used to evaluate knee joint function. It aims to provide standardized assessment for patients with knee joint injuries or after surgery, with a score range of 0 to 100. The higher the score, the better.
Visual Analogue ScorePreoperative baseline; 4 weeks after the operation; 14 weeks after the operation; 6 months after the operationIt is mainly used to rate the degree of patient's pain, with scores ranging from 0 to 10. The lower the score, the better.
