INTRODUCTION
To examine the effects of tap dance (TD) on dynamic plantar pressure, static postural stability, ankle range of motion (ROM), and lower extremity functional strength in patients at risk of diabetic foot (DF).
RESEARCH DESIGN AND METHODS
A randomised, single-blinded, two-arm prospective study of 40 patients at risk of DF was conducted. The intervention group (n=20) received 16 weeks of TD training (60 min/session×3 sessions/week). The control group attended four educational workshops (1 hour/session×1 session/month). Plantar pressure, represented by the primary outcomes of peak pressure (PP) and pressure-time integral (PTI) over 10 areas on each foot, was measured using the Footscan platform system. Secondary outcomes comprised static postural stability, ankle ROM and lower extremity functional strength.
RESULTS
Reductions in intervention group PP (right foot: mean differences=4.5027.1, decrease%=25.672.0; left foot: mean differences=-5.906.33, decrease%=-22.653.2) and PTI at 10 areas of each foot (right foot: mean differences=1.0012.5, decrease%=10.463.6; left foot: mean differences=0.59025.3, decrease%=21.972.6) were observed. Substantial PP and PTI differences were noted at the second through fourth metatarsals, medial heel and lateral heel in the right foot. Substantial PP and PTI differences were detected at metatarsals 1 and 2 and metatarsal 2 in the left foot, respectively. Moderate training effects were found in plantar flexion ROM of both feet, lower extremity functional strength, and length of center-of-pressure trajectory with eyes closed and open (=0.321-0.376, p<0.05).
CONCLUSIONS
A 16-week TD training program can significantly improve ankle ROM, lower extremity functional strength, and static postural stability. To attain greater improvements in plantar pressure, a longer training period is necessary.

介绍
研究目的在于探讨踢踏舞（TD）对糖尿病足（DF）高危患者的足底动态压力、静态姿势稳定性、踝关节活动范围（ROM）和下肢功能力量的影响。
研究设计与方法
采用随机、单盲、双臂前瞻性研究方法，纳入 40 名 DF 高危患者。干预组（n=20）接受 16 周的 TD 训练（60 分钟/次×3 次/周）。对照组参加了 4 次教育讲座（1 小时/次×1 次/月）。使用 Footscan 平台系统测量足底压力，主要结果为每个脚的 10 个区域的峰值压力（PP）和压力时间积分（PTI）。次要结果包括静态姿势稳定性、踝关节 ROM 和下肢功能力量。
结果
干预组右脚的 PP（平均差值=4.5027.1，减少%=25.672.0；左脚的平均差值=-5.906.33，减少%=-22.653.2）和右脚 10 个区域的 PTI（平均差值=1.0012.5，减少%=10.463.6；左脚的平均差值=0.59025.3，减少%=21.972.6）均有显著降低。右脚的第二至第四跖骨、内侧足跟和外侧足跟的 PP 和 PTI 差异显著。左脚的第一和第二跖骨和第二跖骨的 PP 和 PTI 差异显著。双脚的跖屈 ROM、下肢功能力量和闭眼、睁眼时的中心压力轨迹长度均有中度训练效果（=0.321-0.376，p<0.05）。
结论
16 周的 TD 训练方案可显著改善踝关节 ROM、下肢功能力量和静态姿势稳定性。为了获得更大的足底压力改善，需要更长的训练时间。
