“…For this study, an intramuscular depth of 1.6 cm from the skin surface, equal to twice the half-value depth for 3-MHz ultrasound, 32,45 was chosen for temperature measurements because this is roughly the depth of many joints and connective tissues commonly treated with ultrasound. 12 The rate of transducer movement for all treatments was 3 to 4 cm/sec and was controlled using a metronome at 60 beats per minute, as we have previously described.…”

Study Design: A counterbalanced, repeated-measures design with ultrasound device (Omnisound 3000C, Dynatron 950, Excel Ultra III) as the independent variable. The 2 dependent variables were intramuscular (IM) temperature at 6 minutes and at the end of a 10-minute treatment. Objective: To compare IM temperatures produced by identical 3-MHz ultrasound treatments between 3 different ultrasound devices. Background: Most recent studies prescribing intensity and duration parameters for thermal ultrasound treatments have been performed using an Omnisound device, but have not been verified in other common ultrasound devices. Methods and Measures: Six uninjured volunteers (mean age ± SD, 22 ± 3.4 y; mean height ± SD, 171.9 ± 11.0 cm; mean mass ± SD, 66.1 ± 11.1 kg) gave informed consent and served as subjects. Separate ultrasound treatments using identical parameters (3 MHz, 1.5 W/cm 2 , 10 minutes, treatment area equal to twice transducer surface area) were administered at 24 or 48 hours intervals using a different ultrasound device for each treatment. Left medial calf IM temperature was recorded every 20 seconds using implantable thermocouples at a depth of 1.6 cm below the treatment surface. Data were analyzed using MANOVA with Sidak adjusted multiple comparisons post hoc. Results: Tissue heating using the Omnisound device was greater than with either the Dynatron or the Excel. The results of treatments using Dynatron or Excel devices did not differ. The Omnisound was the only device to consistently produce IM temperatures above the 40°C therapeutic threshold and did so in less than 6 minutes. The other devices did not reach this threshold within the 10-minute treatment session. Subjects routinely reported heating sensations approaching discomfort when the IM temperature reached the 40°C therapeutic threshold. Conclusions: Because there are differences in thermal effects between ultrasound devices, our results suggest that recently published parameters for ultrasound intensity and duration parameters will not produce equally therapeutic effects for all ultrasound devices.

“…The depth of ultrasound penetration is described in terms of the halfvalue layer or the depth by which 50% of the ultrasound beam is at+ sorbed in tissue (35). In the muscle tissue model used for this study, this was deemed to be 2.5 cm for the triceps surae muscle at 1 MHz and .8 cm for the same muscle at 3 MHz.…”

“…According to the literature evidences, the approximate half-value depth of 1MHz is about 2.3 cm and 3-MHz continuous ultrasound is about 0.8 cm. Hence, 3MHz is used for superficial tissues up to 2 cm deep and 1MHz is used for deeper tissues up to 5 cm deep [17][18][19] . There are two operating modes of therapeutic ultrasound such as continuous and pulsed mode.…”

Introduction: Temporomandibular joint disorder (TMD) is a collective term given to the disorders affecting the Temporomandibular joint (TMJ), masticatory muscles and their related structures. The aetiology of TMD is complex and their management includes various invasive and non-invasive methods. The increasing trend in non-invasive, non-pharmacological interventions for the management of TMJ pain has led to the development of modalities of physical therapy. Ultrasound is an electrophysical treatment modality used in the management of TMD. The aim of this study is to provide an insight into ultrasound based treatment modalities used for the effective management of TMD. Materials and methods: Electronic database search was carried out in Google Scholar and PubMed using the search terms "ultrasound therapy", "therapeutic ultrasound" and "temporomandibular joint disorders". The results obtained from the database search were screened and included for the review. Commonly used therapeutic ultrasound methods in the management of temporomandibular joint disorders with the treatment protocols, advantages, limitations and other factors to be considered for an effective treatment outcome is discussed in the present review. Conclusion: Various new ultrasound-based TMJ therapeutic modalities may be developed in the near future.
