Primary dysmenorrhea is characterized as painful menstruation without associated pelvic disease and has been considered common among young people of reproductive age. Cryotherapy is a technique aimed at analgesia and anti-inflammatory action. The objective of this study was to analyze the analgesic efficacy of cryotherapy in sedentary youth with primary dysmenorrhea. Methods were included sedentary, affected by primary dysmenorrhea. The analysis of pain intensity by visual analog scale (VAS) and the Brazilian Version of the Wisconsin Brief Pain Questionnaire were used for evaluation. The participants were randomly separated into a control group (CG, = 10) and a cryotherapy group (CryoG, = 10). The evaluations and treatment occurred during a menstrual cycle, with three interventions, in the initial 3 days of higher menstrual flow history report. CG showed a reduction in pain when comparing the 1st with the 4th day of assessment; CryoG showed a daily reduction in VAS; for the pain questionnaire, cryotherapy showed a reduction in interference with sleep dysmenorrhea; and for all other variables, although there was no significant difference, a large effect size was observed. Cryotherapy was effective in reducing pain in women with primary dysmenorrhea, with indication of clinical improvement in daily living activities.
原发性痛经的特征是疼痛的月经而没有相关的盆腔疾病，并且被认为在生育年龄的年轻人中很常见。冷冻疗法是一种旨在镇痛和抗炎作用的技术。本研究的目的是分析冷冻疗法对原发性痛经的久坐不动的年轻人的镇痛效果。方法包括久坐不动，受原发性痛经影响。通过视觉模拟量表（VAS）和巴西版威斯康星简短疼痛问卷分析疼痛强度进行评估。参与者被随机分为对照组（CG，n=10）和冷冻疗法组（CryoG，n=10）。评估和治疗在月经周期内进行，在较高的月经流量历史报告的最初 3 天内进行三次干预。CG 在比较第 1 天和第 4 天的评估时显示出疼痛减轻；CryoG 在 VAS 上显示出每日减轻；对于疼痛问卷，冷冻疗法显示出对睡眠障碍性痛经的干扰减少；对于所有其他变量，尽管没有显著差异，但观察到较大的效应量。冷冻疗法可有效减轻原发性痛经妇女的疼痛，表明日常生活活动的临床改善。
