Amaç: Bu çalışma, ayak banyosunun uyku kalitesine etkisini araştırmak amacıyla 50 yaşlı birey ile tek kör, randomize kontrollü paralel gruplu bir çalışma olarak yürütüldü.
Yöntemler: Veriler “Yaşlı Bilgi Formu” ve “Pittsburgh Uyku Kalitesi İndeksi (PUKİ)” kullanılarak 1 Mayıs 2022 - 1 Temmuz 2022 tarihleri arasında Gümüşhane ili bir Devlet Hastanesinde toplandı. Ayak banyosu grubundaki yaşlılara normal uyku saatinden 50 dakika önce 41-42°C su ile 20 dakika ayak banyosu yapıldı. Kontrol grubuna veri toplama araçlarının uygulanması dışında herhangi bir uygulama yapılmadı. Veriler Ki-kare, Friedman, Wilcoxon İşareti ve Mann-Whitney U testleri ile analiz edildi.
Bulgular: Ayak banyosu grubundaki yaşlılardan elde edilen toplam PSQI ölçümlerinden ve tüm alt bileşenlerin medyan puanlarının en az birinin zamana bağlı olarak farklılık gösterdiği belirlendi (P<.05). Ancak kontrol grubundaki yaşlılardan elde edilen uyku latensi (B2), uyku süresi (B3), alışılmış uyku etkinliği (B4) ve uyku bozukluğu (B5) bileşen ölçümlerinde zamana bağlı olarak istatistiksel olarak anlamlı bir fark olmadığı bulundu (P>.05). Ayrıca, ayak banyosu grubundaki yaşlılarda uygulama boyunca “Alışkanlık Uyku Verimliliği (C4)” alt bileşeni dışındaki tüm PUKİ alt bileşenleri ve toplam PUKİ puanları azaldı.
Sonuç: Sonuç olarak ayak banyosunun yaşlılarda uyku kalitesini arttırdığı görüldü. Bu çalışmadan elde edilen bulgular doğrultusunda, ayak banyosunun çoklu deney grupları ile daha uzun süre karşılaştırılması önerilmektedir.

Objective: This study was conducted as a single-blind, randomized controlled parallel-group study with 50 elderly individuals to investigate the effect of foot bath on sleep quality.
Methods: The data were collected using the “Elderly Information Form” and the “Pittsburgh Sleep Quality Index (PSQI)” between 1 May 2022-1 July 2022 at a State Hospital in Gümüşhane province. The elderly in the foot bath group were given a foot bath with 41-42°C water for 20 minutes 50 minutes before normal sleep hours. No application was made to the control group except for the administration of data collection tools. The data were analyzed with Chi-square, Friedman, Wilcoxon Sign, and Mann-Whitney U tests.
Results: It was determined that at least one of the total PSQI measurements and median scores of all subcomponents obtained from the elderly in the foot bath group differed depending on time (P<.05). However, it was found that there was no statistically significant difference in the sleep latency (B2), sleep duration (B3), habitual sleep efficiency (B4) and sleep disturbance (B5) component measurements obtained from the elderly in the control group depending on time (P>.05). Again, All PSQI subcomponents and total PSQI scores, except for the subcomponent “Habitual Sleep Efficiency (C4)”, decreased throughout the application in the elderly in the foot bath group.
Conclusion: As a result, a foot bath improved sleep quality in the elderly. In line with the findings from this study, it is recommended to compare the foot bath with multiple experimental groups for a longer period of time.
