ARTICLE HIGHLIGHTS

Research background

Suspension training (SET), a method of neuromuscular training that enables the body to carry out active training under unstable support through a suspension therapy system, has been widely used in the field of sports and rehabilitation. However, there have been few reports in the literature on the application of SET to the postoperative rehabilitation of anterior cruciate ligament reconstruction (ACLR) patients.

Research motivation

We hope to explore the effect of SET on neuromuscular function, postural control, and knee kinematics in ACLR patients.

Research objectives

To compare the clinical efficacy between SET protocol and traditional training protocol in ACLR patients.

Research methods

Forty participants were randomized to an SET group or a control group. The SET group subjects participated in a SET protocol over 6 wk. The control group subjects participated in a traditional training protocol over 6 wk. Isokinetic muscle strength of the quadriceps and hamstrings, static and dynamic posture stability test, and relative translation of injured knee were assessed before and after training.

Research results

A total of 37 patients were included in the final analysis (SET group, n = 19; control group, n = 18). The relative peak torque of the quadriceps and hamstrings in both groups increased significantly (P < 0.001), and the SET group increased by a higher percentage than those in the control group (quadriceps: P = 0.004, hamstrings: P = 0.011). After training, both groups showed significant improvements in static and dynamic posture stability (P < 0.01), and the SET group had a greater change than the control group (P < 0.05). No significant improvement on the relative translation of injured knee was observed after training in both groups (P > 0.05).

Research conclusions

SET can improve the postoperative rehabilitation effect of ACLR patients and is worthy of clinical promotion.

Research perspectives

We only focused on the effect of SET on the injured knee. Thus, further studies should be performed to explore its biomechanical impact on the hip and ankle joints of ACLR patients and provide more evidence for the clinical application of SET.
