“…Freeman S et al 25 ) , for instance, found in their test of balance ability with black pepper oil and lavender oil as olfactory stimuli that the COP values (RMS velocity and trajectory length in the medial-lateral and anterior-posterior directions) decreased significantly. Ebihara et al 26 ) also reported that the TUG (Timed Up and Go) test score of the elderly significantly decreased after being given olfactory stimuli of lavender oil and grapefruit oil. Sakamoto et al 27 ) also found an interesting result: seniors showed significantly lowered risk of falls after being given olfactory stimuli consisting of a lavender scent for 12 months.…”

“…Some recent research has suggested that olfactory stimulation may increase the postural stability of the elderly 25 ) . It has also been reported that olfactory stimulation increased the gait ability of the elderly 26 ) and that it decreased their risk of falls 27 ) . Many studies have been carried out to identify the relationship between olfactory stimulation and postural control, but not much has been reported on stroke patients.…”

[Purpose] The present study attempted to identify the effect of olfactory stimulation on the balance ability of stroke patients. [Subjects] Thirty-three (33 males) stroke patients participated in the study. The stroke patients were divided into three groups: a black pepper oil (BPO) group (n=11), lavender oil (LVO) group (n=11), and distilled water (DW) group (n=11). [Methods] Two sessions (control trial/stimulus trial) of Romberg’s test (eyes open 1 min/eyes closed 1 min) were conducted on a force platform to measure the data for the COP (center of pressure). Olfactory stimulation was provided at as a stimulus. [Results] With the eyes open, a statistically significant difference was found in average anterior posterior displacement (Ymean) and average medial lateral displacement (Xmean) among the three groups when comparing the groups before and after stimulation. The comparison between the eyes open and eyes closed conditions in each group showed a significant difference in the area of the 95% confidence ellipse (area) and Xmean of the BPO group and in the area of the LVO group (area, Xmean). [Conclusion] The findings indicate that the interaction of brain areas activated by the olfactory stimulation exerts an influence on the balance ability of stroke patients.

“…A previous study showed that olfactory stimulation using lavender oil improved balance in elderly people . In addition, another recent study reported that gait performance as measured using the Timed Up and Go test and 10‐m walking speed significantly improved after exposure to lavender olfactory stimulation . Although these studies demonstrated a transient effect of lavender olfactory stimulation, long‐term exposure to continuous lavender olfactory stimulation has not been investigated.…”

“…10 In addition, another recent study reported that gait performance as measured using the Timed Up and Go test and 10-m walking speed significantly improved after exposure to lavender olfactory stimulation. 11 Although these studies demonstrated a transient effect of lavender olfactory stimulation, long-term exposure to continuous lavender olfactory stimulation has not been investigated. It is conceivable that, if individuals were exposed continuously to lavender olfactory stimulation, the stabilizing effects of lavender odor on gait performance might prevent falls in frail elderly people.…”

“…We hypothesized that the perception of food-related odors during cooking could modulate the motor system by driving the motivation to eat. Although a number of studies have found beneficial effects of food-related odors on swallowing [8, 9], postural stability [10], gait performance [11], and grasping movement toward a food object [12], most of the food-related odors so far examined in relation to the motor system were trigeminal stimulants such as black pepper and lavender [8–11]. Therefore, the relationship between food-related odors and the motor system has not yet been fully clarified.…”

Background We have observed changes in body reactions during cooking, which is one of the treatment modalities used in occupational therapy. The perception of food-related odors during cooking may have behavioral effects on human activities through the activation of appetitive motivation. Objectives We investigated whether odor components contained in seasonings could facilitate the human motor system and the specificity of this effect. Methods The subjects were 72 healthy adults, randomly assigned to a water exposure group, a phenylethyl alcohol (PEA, pleasant rose-like odor) exposure group, and a Japanese soy sauce (Koikuchi Shoyu) exposure group (n = 24 each). The subjects' olfactory sense was stimulated by their sniffing of three different test tubes containing 5 ml of water, PEA, or Japanese soy sauce for 20 sec while they were seated. The modified Functional Reach Test (mFRT), which mimics a functional activity that is required in daily living and assesses a reliable measure of sitting balance, was performed prior to and immediately after the sniffing. Results Sniffing the soy sauce increased the subjects' mFRT scores. This facilitation effect was odorant-specific and was absent when the subjects were presented with water or PEA. Conclusions Cooking interventions are aimed at improving tool-handling skills such as using knives and chopsticks. The results indicate that treatment interventions using odors of seasonings would be effective for improving subjects' physical functions.
