Purpose: Burn injury with pre-existing diabetes has poorer outcomes and complications. Balance and functional mobility are disturbed in diabetic patients with burn injury which increase the risk of total morbidity. The aim of the current study was to evaluate the impact of vibrational training as an additional intervention on postural balance, balance confidence and functional mobility in type 2 diabetic patients with lower limb burn injury.
Patients and Methods: Thirty-eight type 2 diabetic patients of both sexes with healed lower limb burn were randomly assigned into two equal groups: the vibration group and the control group. The vibration group received whole body vibration (WBV), 3 sessions a week for 8 weeks, in addition to the selected exercise program (balance exercises and resisted exercises), while the control group only received the selected exercise program. Biodex Balance System was used to assess the dynamic balance score, the Activities-specific Balance Scale to assess balance confidence and the timed up and go test to assess the functional mobility. All measurements were obtained before and at the end of the study after 8 weeks of treatment.
Results: Marked improvement in all dynamic balance indices; overall stability index, antero-posterior stability index and medio-lateral stability index, balance confidence and the functional mobility were obtained in both the vibration and the control groups (P< 0.05), whereas post-treatment comparison between groups revealed a statistically significant difference in favor of the vibration group in all measured variables.
Conclusion: Based on the results of the current study, it is possible to conclude that adding WBV training for an 8-week duration to a selected exercise program (balancing and resisted exercises) seems to be effective; in improving postural balance, balance confidence, as well as improving the functional mobility in type 2 diabetic patients with lower limb burn injury.

低振动训练作为对下肢烧伤 2 型糖尿病患者姿势平衡、平衡信心和功能活动性的额外干预：一项随机临床试验

目的：已有糖尿病的烧伤结果和并发症较差。烧伤的糖尿病患者的平衡和功能活动受到干扰，这增加了总发病率的风险。本研究的目的是评估振动训练作为额外干预措施对下肢烧伤 2 型糖尿病患者姿势平衡、平衡信心和功能活动度的影响。
患者和方法：将38例下肢烧伤愈合的男女2型糖尿病患者随机分为两组：振动组和对照组。振动组接受全身振动（WBV），每周 3 次，共 8 周，除了选定的锻炼计划（平衡锻炼和抗阻锻炼），而对照组只接受选定的锻炼计划。Biodex 平衡系统用于评估动态平衡评分，使用特定活动平衡量表评估平衡信心，并使用定时启动测试来评估功能流动性。在治疗 8 周后，在研究结束之前和结束时获得所有测量值。
结果：各项动平衡指标显着提高；振动组和对照组均获得整体稳定性指数、前后稳定性指数和中外侧稳定性指数、平衡信心和功能活动度（P<0.05），而治疗后组间比较差异有统计学意义有利于所有测量变量的振动组。
结论：根据当前研究的结果，可以得出结论，在选定的运动计划（平衡和抗阻运动）中加入为期 8 周的 WBV 训练似乎是有效的；在改善姿势平衡、平衡信心以及改善下肢烧伤 2 型糖尿病患者的功能活动度方面。
