DOES MANUAL LYMPH DRAINAGE AFFECT AUTONOMIC FUNCTIONS IN HEALTHY WOMEN?: A RANDOMIZED CONTROLLED STUDY

Abstract

Purpose: This study aimed to examine the effects of manual lymph drainage (MLD) on autonomic functions in healthy women. Methods: 40 women were included in the study. In the single-blind randomized controlled study, the participants were divided into 3 groups MLD, sham MLD, and control group. After evaluating the demographic information, blood pressure (BP), and heart rate variability (HRV) of the participants, the cold pressure test was applied. Immediately after the test, BP and HRV were re-evaluated. The MLD group received MLD applications. A sham protocol was applied to the sham MLD group. The control group was asked to lie on their back for 10 minutes. After the application, participants were re-evaluated. Results: While systolic BP decreased in all 3 groups with the cold pressure test, it continued to decrease after the application in the sham MLD group (p<0.05). While there was a significant decrease in heart rate in the MLD, sham MLD, and control groups after the cold pressure test, a significant decrease continued only in the MLD group after the application (p<0.05). The RMSSD parameter of HRV increased significantly only in the MLD group after the application (p<0.05). The RR interval value increased both after the cold pressure test and after the application in MLD and control groups (p<0.05). Conclusion: MLD can be used in the activation of parasympathetic nervous system (PNS) due to the change in HRV parameters. PNS activation can be an important therapeutic approach in the treatment of some diseases, especially those with autonomic involvement.

MANUEL LENF DRENAJI SAĞLIKLI KADINLARDA OTONOMİK FONKSİYONLARI ETKİLER Mİ?: BİR RANDOMİZE KONTROLLÜ ÇALIŞMA

Öz

Amaç: Bu çalışma, sağlıklı kadınlarda manuel lenf drenajının (MLD) otonomik fonksiyonlar üzerindeki etkilerini incelemeyi amaçlamaktadır. Yöntem: 40 sağlıklı kadın çalışmaya dahil edildi. Tek kör randomize kontrollü çalışmada katılımcılar MLD, sham MLD ve kontrol grubu olarak 3 gruba ayrıldı. Katılımcıların demografik bilgileri, kan basıncı ve kalp hızı değişkenliği (KHD) değerlendirildikten sonra soğuk basınç testi uygulandı. Testin hemen ardından kan basıncı ve KHD yeniden değerlendirildi. MLD grubuna MLD uygulamaları yapıldı. Sham MLD grubuna sham protokolü uygulandı. Kontrol grubundan 10 dakika sırt üstü yatmaları istendi. Uygulama sonrası katılımcılar tekrar değerlendirildi. Sonuçlar: Sistolik kan basıncı soğuk basınç testi ile her 3 grupta da düşerken, sham MLD grubunda uygulama sonrası düşmeye devam etti (p<0,05). Soğuk basınç testi sonrası MLD, sham MLD ve kontrol gruplarında kalp atım hızında anlamlı azalma olurken, uygulama sonrası sadece MLD grubunda anlamlı düşüş devam etti (p<0,05). KHD'nin RMSSD parametresi uygulama sonrası sadece MLD grubunda anlamlı olarak arttı (p<0,05). RR aralığı değeri hem soğuk basınç testi hem de uygulama sonrası MLD ve kontrol gruplarında arttı (p<0,05). Tartışma: MLD, KHD parametrelerindeki değişiklik nedeniyle parasempatik sinir sisteminin aktivasyonunda kullanılabilir. Parasempatik sinir sistemi aktivasyonu özellikle otonomik etkilenim olan bazı hastalıkların tedavisinde önemli bir tedavi yaklaşımı olabilir.
