The effectiveness of an exercise programme on knee loading, muscle co-contraction, and @entity158 in XXXX with medial knee osteoarthritis: A pilot study.

BACKGROUND: @entity571 ( @entity571 ), which increases knee loading, muscle co-contraction, and @entity158 , is a mechanical disease that requires biomechanical exploration to reduce @entity158 in the knee. Therefore, this article aims to investigate the effectiveness of an exercise programme on the aforementioned outcomes in @entity1 with medial knee @entity571 . METHODS: Cohort pilot study design. A total of 19 @entity1 with knee @entity571 attended a six-week group exercise programme integrated with self-management education. The following outcomes were assessed before and after the exercise programme: external knee adduction moment (EKAM), knee adduction angular impulse (KAAI), knee antagonist muscle co-contraction, and @entity158 subscale of the @entity3331 and @entity571 outcome score (KOOS). RESULTS: Of the 19 @entity1 , 14 completed the study. The EKAM and KAAI did not show statistical significance post-exercise intervention (p=0.21-0.7 and 0.56, respectively). Muscle co-contraction between vastus lateralis and biceps femoris muscles decreased in early-stance (64.78 (44.35) compared with 38.10 (23.10), p=0.01) and mid-stance (27.62 (32.12) compared with 14.94 (17.40), p=0.04). A corresponding significant @entity158 reduction was observed (p=0.00) with a median (range) of 51.50 (47.00 to 62.50) at week 6 compared with 34.50 (29.25 to 41.25) at baseline. CONCLUSION: This is the first known study to explore the effect of an exercise programme on knee loading and muscle co-contraction in @entity1 with @entity571 . Although the value of EKAM did not change, the findings suggest that the reduction in vastus lateralis and biceps femoris co-contraction might be the mechanism behind the reduction of @entity158 .
