Abstract:

Objective To explore the effect of trunk control training during unstable sitting on knee pain and function in patients with patellofemoral pain syndrome.

Methods From January, 2019 to December, 2021, 41 patients with patellofemoral pain syndrome in Beijing Rehabilitation Hospital were randomly divided into control group (n = 20) and experiment group (n = 21). Both groups accepted routine rehabilitation, and the experiment group accepted trunk control training during unstable sitting in addition, for four weeks. They were assessed with Visual Analogue Scale for pain (VAS) and Anterior Knee Pain Scale (AKPS), and measured stability indexes with Balancer before and after treatment.

Results All the VAS score, AKPS score, and the overall, anterior-posterior and left-right stability indexes improved in both groups after treatment (|t| > 12.089, P < 0.001); and improved more in the experiment group than in the control group (|t| > 5.864, P < 0.001).

Conclusion Trunk control training during unstable sitting may improve knee pain and function, and motor control.

Key words: patellofemoral pain syndrome, trunk control training, rehabilitation
