Purpose: To investigate the effects of heat (surface and deep) and cold on the range of motion of the knee. Methods: A total of 40 volunteers were randomly allocated into four groups, with 10 participants in each group. The control group had no intervention, the infrared group received an application of surface heat conducted through an infrared device, the shortwave group received deep heating through a shortwave device, and the cryotherapy group had ice packs placed on them. A blind measurer performed the flexibility evaluation using a goniometer coupled to a board that evaluated range of movement of the knee. Data were statistically analysed by one-way analysis of variance and Tukey's comparison (for comparison between groups) and paired t-student tests (for before and after comparisons) to determine differences between groups, with a significance level of p<0.05. Findings: The infrared, cryotherapy and shortwave groups showed an increase in the range of motion compared with the control group. It was observed that the control and infrared groups showed no significant differences before and after application (p>0.05). However, the cryotherapy and shortwave groups demonstrated an effective increase (p<0.05). Conclusions: The three heating and cooling techniques caused a favourable increase of range of movement compared with no intervention. However, the shortwave and cryotherapy interventions were more effective in increasing the knee joint's range of motion.
Introdução: A auriculoterapia é uma alternativa de tratamento para a ansiedade e estresse. Essa terapia milenar vem se mostrando bastante eficaz em sanar as consequências do estresse e dor. Objetivo: Analisar os efeitos da auriculoterapia para o tratamento de dor e estresse em mulheres trabalhadoras de meia-idade em um estudo preliminar. Métodos: Para tal, foi realizada uma pesquisa transversal, piloto, descritiva e quantitativa, em que foram recrutadas 20 mulheres de 20- 50 anos. As participantes foram avaliadas por 3 questionários antes, durante e após o tratamento por auriculoterapia. Este consistiu na aplicação de sementes de mostarda em 3 pontos específicos da orelha (Shenmen, Rim e Tronco Cerebral), por um período de 8 semanas. Resultados: Observou-se uma diminuição significativa da pontuação de estresse (p<0,05) e, diminuição significativa da dor (p<0,05) após tratamento de 4 semanas e 8 semanas comparado com antes da intervenção. Conclusões: Através deste estudo, a auriculoterapia demonstrou reduzir a dor e o estresse, quando avaliado em mulheres trabalhadoras de meia idade.
