OBJECTIVE: The purpose of this study was to evaluate associations between skin surface temperature and pressure pain tolerance thresholds (PPTs) of asymptomatic individuals exposed to cryotherapy and thermotherapy. METHODS: Twenty-two asymptomatic female university students aged between 18 and 35 years underwent thermography and algometry assessments at 6 points in both knees before, immediately after, and 20 minutes after the application of frozen (cryotherapy) or heated (thermotherapy) gel bags in the right knee for 20 minutes. Data were analyzed by 1-way analysis of variance, Student test, and Pearson or Spearman correlation tests. RESULTS: There was a significant change in skin surface temperature after cryotherapy and thermotherapy, which was maintained after 20 minutes of withdrawal ( < .001). After the intervention, no significant differences were observed regarding PPT compared with the baseline measurements, nor between the experimental and control knees. CONCLUSION: Cryotherapy and thermotherapy produced significant changes in the temperature of the evaluated points after their application. No differences in pain tolerance were observed in these asymptomatic participants. There was little association between skin surface temperature and PPT in the knees of healthy women after application of the resources.
目的:本研究旨在评估接受冷冻疗法和热疗法的无症状个体的皮肤表面温度与压力疼痛耐受阈值(PPTs)之间的关联。 方法:22名年龄在18至35岁之间的无症状女大学生在右膝应用冷冻(冷冻疗法)或加热(热疗法)凝胶袋20分钟之前、之后立即以及之后20分钟,对双膝的6个点进行了热成像和痛觉测量评估。数据通过单因素方差分析、学生检验以及Pearson或Spearman相关性检验进行分析。 结果:冷冻疗法和热疗法后皮肤表面温度有显著变化,在撤去治疗20分钟后仍保持(P <.001)。干预后,与基线测量相比,PPT没有显著差异,实验膝和对照膝之间也没有显著差异。 结论:冷冻疗法和热疗法应用后,所评估点的温度产生了显著变化。在这些无症状参与者中未观察到疼痛耐受性的差异。应用这些疗法后,健康女性膝盖的皮肤表面温度与PPT之间几乎没有关联。
