RESUMO
BACKGROUND: Knee osteoarthritis is the most common articular disease, and non-medical treatment of this disease has attracted the attention of researchers. The purpose of this study was to compare the effects of aromatherapy and massage therapy on knee pain, morning stiffness, daily life function, and quality of life in patients with knee osteoarthritis. METHODS: This is a clinical trial. In this study, 93 patients referred to the Imam Ali Hospital (Physical Therapy Clinic) who entered the study were randomly divided into three groups including massage therapy (n = 31), aromatherapy (n = 31), and the control (n = 31). The data gathering tools were a demographic characteristics questionnaire and the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire. The questionnaire was completed before intervention and at the 5th and 10th sessions after intervention in all three groups. Data were analyzed by SPSS software version 20, and Chi-square, Fisher's exact test, repeated measures test, one-way ANOVA test, and Tukey's post hoc test were used for analysis. RESULTS: The study shows that mean score subscale Symptoms and dryness in the 5th session and 10th session of intervention in the aromatherapy group is significantly higher than in the control group (p < 0.05). The massage therapy group had the highest pain score at the beginning of the intervention, but at the end of the 10th session of intervention had the least pain score. Mean score subscale Performance of daily life in the 5th session and 10th session of intervention in the aromatherapy group is significantly higher than in the control group (p < 0.05). Mean score in the subscale Performance, exercise, and recreational activities significantly differs between the aroma therapy and massage therapy groups compared with the control group in all times of interventions (p < 0.05), and in the mean score in the subscale Quality of life, there is no significant difference between the groups in all times of interventions (p > 0.05). CONCLUSION: The use of both massage therapy and aromatherapy is recommended for patients with knee osteoarthritis. Interventions should be prolonged for at least 6 months in patients so their effects appear on the patient.
