Using lavender oil as an olfactory stimulus during vestibular rehabilitation exercises can improve balance and reduce fear of falling in people with multiple sclerosis.
Purpose To evaluate the effect of using lavender oil as an olfactory stimulus with vestibular rehabilitation (VR) on balance, fear of falling down, and activities of daily living of people with multiple sclerosis. Methods Forty participants were randomly assigned into experimental and control groups. The experimental group did the VR exercises while smelling the lavender oil scents. The control group did the VR exercises without it. Both groups did the exercises in ten 45-min sessions. We assessed the participants with the timed up and go (TUG) test, Berg balance scale (BBS), fall efficacy scale - international (FES-I), and the 29-item multiple sclerosis impact scale (MSIS-29). We did the tests at the baseline and after the last exercise session. Results The experimental group performed significantly better in the BBS (p = 0.007), TUG (p = 0.045), and FES-I (p = 0.016) tests as well as in the MSIS-29's psychological subscale (p = 0.034) than did the control group. Conclusions Using lavender oil as olfactory stimulus while doing the VR exercises can improve balance and reduce fear of falling down compared to doing the VR exercises without it in people with multiple sclerosis.
