Aromatherapy massage with lavender essential oil and the prevention of disability in ADL in patients with osteoarthritis of the knee: A randomized controlled clinical trial.

BACKGROUND

Knee osteoarthritis is considered as one of the most prevalent musculoskeletal disorders which leads to joint degeneration and consequently disability in activities of daily living. This study aimed to evaluate the effects of aromatherapy massage with lavender essence on activities of daily living of patients with knee osteoarthritis.

METHODS

This is a single-blinded, randomized clinical trial. A total of 90 patients with osteoarthritis of the knee referring to the outpatient rheumatology clinics affiliated to Birjand University of Medical Sciences were selected via convenience sampling method. The participants were randomly assigned into three groups: intervention group (aromatherapy massage with lavender essential oil), placebo group (massage with almond oil) and control group (without massage). The activities of daily living of patients was evaluated according to the Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) at baseline, immediately after the intervention, 1 week, and 4 weeks after the intervention. Data were analyzed using SPSS statistical software version 16.

RESULTS

The activities of daily living of patients were significantly improved immediately and 1 week after the intervention in the intervention group compared with their initial status (p < .001) and that of the control group (p < .001 and p = .03 respectively). However, 4 weeks after the intervention, there was no significant difference between the groups according to the Western Ontario and McMaster Universities Osteoarthritis index (p = .95).

CONCLUSIONS

Aromatherapy massage with lavender essential oil may reduce the incidence of activities of daily living disability in patients with osteoarthritis of the knee. However, further studies are required to confirm findings of this study.
