The aim of this study is to assess the efficacy of aquatic exercise on pain, gait, and balance among elderly patients with knee osteoarthritis.
We performed a randomized controlled trial at a university hospital. Overall, 32 men with knee osteoarthritis, aged ≥ 60 years, were included. Pain, balance, and gait were evaluated before and 2 months after interventions. The group control used acetaminophen and followed lifestyle recommendations. The intervention group performed the aquatic exercise three sessions per week for 8 weeks.
At the end of the study, mean pain scores were significantly different between the groups ( = 0.010). Within-group analyses showed that group intervention experienced significant pain relief ( = 0.019), whereas group control did not show the significant change ( = 0.493). There was significant improvement in favor of aquatic exercise with regard to static ( = 0.001) and dynamic ( = 0.001) balance, step length ( = 0.038), stride length ( < 0.001), and cadence ( < 0.001). However, we did not find a significant difference in step time and width between the two groups.
Aquatic exercise would be beneficial in decreasing subjective pain of osteoarthritis. There are some recognizable improvements in patients' gait and balance as well.
本研究旨在评估水上运动对老年膝骨关节炎患者疼痛、步态和平衡的疗效。
我们在一家大学医院进行了一项随机对照试验。总共纳入了32名年龄≥60岁的膝骨关节炎男性患者。在干预前和干预2个月后对疼痛、平衡和步态进行评估。对照组使用对乙酰氨基酚并遵循生活方式建议。干预组每周进行三次水上运动，共8周。
在研究结束时，两组之间的平均疼痛评分有显著差异（P = 0.010）。组内分析表明，干预组疼痛明显减轻（P = 0.019），而对照组没有显著变化（P = 0.493）。在静态（P = 0.001）和动态（P = 0.001）平衡、步长（P = 0.038）、步幅（P < 0.001）和步频（P < 0.001）方面，水上运动有显著改善。然而，我们发现两组之间的步时和步宽没有显著差异。
水上运动有助于减轻骨关节炎的主观疼痛。患者的步态和平衡也有一些明显改善。
