足跟抬高任务可用于评估糖尿病和周围神经病变患者的中足和踝关节运动功能障碍。量化脚跟上升过程中的运动协调对于更好地了解足部疾病患者的潜在有害运动策略非常重要;然而，糖尿病患者的协调性以及有限偏移对协调性的影响尚未得到充分了解。60例糖尿病合并周围神经病变患者、22例老年对照组和25例年轻对照组进行了单侧足跟抬高任务。测量中足（前足相对于后足）矢状面和踝关节（后足相对于小腿）矢状面和额状面运动学，并将其标准化为时间（0至100%）。计算各组中个体间的互相关系数。用图解法解释了足跟上提过程中中中足和踝关节位移与交叉相关系数的关系。与老年对照组相比，糖尿病和周围神经病变患者在足跟抬高过程中的中足和踝交叉相关系数显著降低（p=0.003 - 0.007）。老年人和年轻人的中足和踝关节交叉相关系数在脚跟上升过程中没有差异（p=0.059 - 0.425）。图形数据显示，两个关节的偏移和较高的互相关系数的趋势。一些个体的低偏移表现出较高的互相关系数。足部病变，而不是老化，损害中足和踝关节运动协调在脚跟上升任务。调查运动协调以及关节偏移将更好地告知和表征脚跟上升任务期间中足和踝关节的动态运动。
A heel rise task can be used to evaluate midfoot and ankle movement dysfunction in people with diabetes mellitus and peripheral neuropathy. Quantifying movement coordination during heel rise is important to better understand potentially detrimental movement strategies in people with foot pathologies; however, coordination and the impact of limited excursion on coordination is not well-understood in people with diabetes. Sixty patients with diabetes mellitus and peripheral neuropathy, and 22 older and 25 younger controls performed unilateral heel rise task. Midfoot (forefoot relative to hindfoot) sagittal and ankle (hindfoot relative to shank) sagittal and frontal kinematics were measured and normalized to time (0 to 100%). Cross-correlation coefficients were calculated across individuals in each group. A graphical illustration was used to interpret the relationship of midfoot and ankle excursion and cross-correlation coefficient during heel rise. People with diabetes mellitus and peripheral neuropathy showed significantly lower midfoot and ankle cross-correlation coefficients during heel rise compared to older controls (p=0.003 – 0.007). There was no difference in the midfoot and ankle cross-correlation coefficients during heel rise for the older and younger controls (p=0.059 – 0.425). The graphic data illustrated a trend of greater excursion of two joints and a higher cross-correlation coefficient. Some individuals with lower excursion showed a high cross-correlation coefficient. Foot pathologies, but not aging, impairs midfoot and ankle movement coordination during heel rise task. Investigating both movement coordination as well as joint excursion would better inform and characterize the dynamic movements of midfoot and ankle during heel rise task.
