زمينه و هدف: مطالعات نشان ميدهند رايحه سبب بهبود تعادل سالمندان ميگردد. هدف اين مطالعه، بررسي اثر محرك بويايي بر تعادل افراد جوان و مقايسه آن در مردان و زنان بود.
روش بررسي: آزمونهاي تعادل استاتيك ايستادن روي يك پا و تعادل ديناميك با استفاده از دستگاه سنجش تعادل بايودكس در دو مرحله پيش و پس از اعمال رايحه بر روي 40 داوطلب سالم در فاصله بهمن 1395 تا ارديبهشت ماه 1396 انجام شد.
يافتهها: تفاوت معناداري در شاخصهاي تعادل ايستا و ديناميك بر اساس شرايط وجود و عدم وجود رايحه ديده نشد. تفاوت معناداري در شاخصهاي ثبات كلي (0/034=P) و قدامي-خلفي (0/019=P) براي تعامل بين اثر جنسيت و رايحه و در شاخصهاي ثبات كلي (0/008=P) و داخلي-خارجي (0/023=P) براي اثر جنسيت در خانمها مشاهده گرديد.
نتيجهگيري: محرك بويايي تاثيري بر تعادل افراد جوان سالم نداشت اما رايحه بهطور معناداري اثر خاص جنسيتي دارد كه اين امر ميتواند به دليل حساسيت بيشتر خانمها نسبت به بو باشد.

Background: The previous studies showed that the odor can improve balance in the
elderly. The purpose of the current study was to determine the effect of olfactory
stimulus and its gender specific effect on the balance of young healthy people.
Methods: This is a pretest-posttest semi experimental study comprised 40 healthy
volunteers (age range 18-73 years) from February 2016 through May 2017. The static
balance test with one-leg standing time (OLST) and dynamic balance test using Biodex
balance system to measure overall stability index (OSI), anterior/posterior stability
index (APSI), medial/lateral stability index (MLSI) and overall limit of stability index
(OLOSI) randomly were performed before and after application of lavender scant as the
olfactory stimuli. A two-way repeated measurement ANOVA was used to assess the
effect of olfactory stimulus conditions and gender on dynamic balance indexes (OSI,
APSI, MLSI, and OLOSI). Since the distribution of the OLST was not normal, the
generalized estimating equations (GEE) method was used. Significance level of P<0.05
was adopted for all comparisons. Means are reported±SD unless otherwise stated. SPSS
software, version 21 (IBM SPSS, Armonk, NY, USA) was used to carry out all
statistical analyses.
Results: The results showed that in comparison of the two different conditions (no
odor/with odor), there was no significant difference in any of static and dynamic
balance indexes (P>0.05). There were significant differences in relation to the
interaction of the gender and odor in OSI (P=0.026), APSI (P=0.019). For gender, there
were statistically significant differences in OSI (P=0.002, F (1,38)=11.649), APSI
(P=0.001, F(1,38)=12.057), and MLSI (P=0.007, F(1,38)=8.228) for females.
Conclusion: Although there was no effect of odor on balance control of young healthy
people, we found that the odor has gender specific effect. This is probably due to the
more sensitivity of females to the odor.
