Evaluation of the effect of ultrasonic heating and exercise heating on muscles by ultrasound elastography: An experimental clinical trial

Abstract

Aim: Ultrasound (US) has been used for therapeutic purposes for many years due to its biological beneficial effects. İn this report we compare the effect of therapeutic ultrasonic heating with exercise-heating on the gastrocnemius / soleus muscles by quantitative measurements of ultrasound elastography.

Methods: İt is designed as a single blind experimental clinical study. Fourty (40) healthy male patients aged between 19-23 years were included randomly in the study. To the first group, we applied a continuous wave therapeutic US on both calfs (symmetrically) consisting gastrocnemius / soleus muscle groups at a frequency of 3 Mhz, 2 w / cm2 dose, for 6 minutes. To the second group, we applied a 15-minute jogging exercise program. Bilateral, symmetric measurements were made in the first 5 minutes with a wide band linear probe, US elastography before and after application. 

Results: A statistically significant decrease in ultrasound elastography strain value (UESV) after therapeutic US in gastrocnemius / soleus muscle groups was observed (p < 0.001 / p < 0.001). There was no statistically significant change in UESV in the gastrocnemius / soleus muscle groups in  the jogging group (p = 0.792 / p =0.187). When the percentages of ultrasound elastography strain ratio (UESR) were examined, there was a significant difference in the change of percentages in the gastrocnemius / soleus muscle groups in both groups (p = 0.005/ p = 0.001). According to this, in both muscle groups, the elasticity increased and the stiffness decreased in group 1 and in group 2, the stiffness increased in some cases and decreased in some, and in overall it was observed to increase. 

Conclusion: Therapeutic US-heating is an effective, reliable method that generally increases elasticity and reduces stiffness in calf muscles than exercise-heating.

Egzersizle ısıtma ile ultrasonik ısıtmanın kaslarındaki etkisinin ultrason elastografi ile değerlendirimi: Deneysel bir klinik çalışma

Öz

Amaç: Ultrason (US), biyolojik yararlı etkileri nedeniyle yıllarca tedavi amaçlı kullanılmıştır. Bu yazıda gastroknemius / soleus kaslarının egzersizle ısıtma ile terapötik ultrasonik ısıtmanın etkisini ultrason elastografi (UE) ile kantitatif ölçümleri karşılaştırdık.

Yöntemler: Çalışma tek kör deneysel klinik olarak tasarlanmıştır. Çalışmaya 19-23 yaşları arasında 40 sağlıklı erkek hasta randomize dahil edilmiştir. İlk grupta, 3 MHz frekansında gastroknemius / soleus kas gruplarını içeren her iki kalf kasları (simetrik olarak) üzerine 6 dakika, 2 w / cm2 doz sürekli akım terapötik US uyguladık.  İkinci gruba 15 dakikalık koşu egzersiz programı uyguladık. Bilateral, simetrik ölçümler ilk 5 dakikada geniş bant lineer prob, US elastografi ile uygulama öncesi ve sonrası yapıldı.

Bulgular: Gastroknemius / soleus kas gruplarında terapötik US sonrası ultrason elastografi strain değerinde (UESV) istatistiksel olarak anlamlı bir düşüş gözlendi (p <0,001 / p <0,001). Koşu grubundaki gastroknemius / soleus kas gruplarında UESV'de istatistiksel olarak anlamlı bir değişiklik yoktu (p = 0,792/ p = 0,187).

Ultrason elastografi gerim oranının (UESR) yüzdeleri incelendiğinde, her iki grupta da gastroknemius / soleus kas gruplarında yüzde değişiminde anlamlı bir fark vardı (p = 0,005 / p = 0,001). Buna göre, her iki kas grubunda da elastikiyet artmış ve grup 1'de ve grup 2'de sertlik azalmış, bazı durumlarda sertlik artmış iken bazılarında azalmış ve genel olarak artmıştı.

Sonuç: Terapötik US-ısıtma, genel olarak elastikiyeti arttıran ve baldır kaslarındaki sertliği egzersiz-ısıtmaya göre azaltan etkili ve güvenilir bir yöntemdir.
