The purpose of this study was to compare the effects of cold, heat, and contrast bath treatments on the amount of edema in first- and second-degree sprained ankles during the postacute phase of rehabilitation. Thirty subjects with postacute sprained ankles were assigned to a cold (n = 10), heat (n = 10), or contrast bath (n = 10) treatment group. A specially constructed tank was used to take pretreatment and posttreatment volumetric measurements of subjects' sprained ankles. Descriptive statistics, a 3 x 3 two-way analysis of variance for repeated measures, and Tukey's Honestly Significant Difference post hoc test revealed that cold therapy produced the least edema in subjects with sprained ankles (p less than .05). All three treatments (cold, heat, and contrast bath) produced an increase in the amount of edema in the postacute sprained ankles of the subjects. Heat and contrast bath therapy produced almost identical increases in the amount of ankle edema on each of the three days of the study. We concluded that cold therapy is the most appropriate of the three treatments if the therapeutic objective is to minimize edema before rehabilitative exercise during the third, fourth, and fifth days postinjury for first- and second-degree ankle sprains.
本研究的目的是比较冷疗、热疗和冷热交替浴疗法对一、二度踝关节扭伤康复后期水肿量的影响。30名踝关节扭伤处于康复后期的受试者被分为冷疗组（n = 10）、热疗组（n = 10）或冷热交替浴组（n = 10）。使用特制的水箱对受试者扭伤的踝关节进行治疗前和治疗后的容积测量。描述性统计、重复测量的3×3双向方差分析以及Tukey氏真实显著差异事后检验显示，冷疗使踝关节扭伤受试者的水肿最少（p < 0.05）。所有三种治疗方法（冷疗、热疗和冷热交替浴）均使受试者康复后期扭伤的踝关节水肿量增加。在研究的三天中，热疗和冷热交替浴疗法使踝关节水肿量增加的幅度几乎相同。我们得出结论，如果治疗目标是在一、二度踝关节扭伤受伤后的第三天、第四天和第五天进行康复锻炼前将水肿降至最低，那么冷疗是这三种治疗方法中最合适的。
