  • an evaluation of safety guidelines to restrict exposure to stray radiofrequency radiation from Short Wave Diathermy units
    Physics in Medicine and Biology, 2004
    Co-Authors: Nora Shields, Neil Ohare, John Gormley
    Abstract:

    Short-Wave Diathermy (SWD), a form of radiofrequency radiation used therapeutically by physiotherapists, may be applied in continuous (CSWD) or pulsed (PSWD) mode using either capacitive or inductive methods. Stray radiation emitted by these units may exceed exposure guidelines close to the equipment. Discrepant guidelines exist on a safe distance from an operating unit for operators and other personnel. Stray electric (E-field) and magnetic (H-field) field strengths from 10 SWD units in six departments were examined using a PMM 8053 meter and two isotropic probes (EP-330, HP-032). A 5 l saline phantom completed the patient circuit. Measurements were recorded in eight directions between 0.5 m and 2 m at hip and eye levels while the units operated at maximum output and data compared to current guidelines. Results found stray fields from capacitive CSWD fell below operator limits at 2 m (E-field 4.8–39.8 V/m; H-field 0.015–0.072 A/m) and at 1 m for inductive CSWD (E-field 0–36 V/m; H-field 0.01–0.065 A/m). Capacitive PSWD fields fell below the limits at 1.5 m (E-field 1.2–19.9 V/m; H-field 0.002–0.045 A/m) and at 1m for inductive PSWD (E-field 0.7–4.0 V/m; H-field 0.009–0.03 A/m). An extra 0.5 m was required before fields fell below the guidelines for other personnel. These results demonstrate, under a worst case scenario, emissions from SWD exceed the guidelines for operators at distances currently recommended as safe. Future guidelines should include recommendations for personnel other than physiotherapists.

  • Short-Wave Diathermy and pregnancy : what is the evidence?
    Advances in Physiotherapy, 2003
    Co-Authors: Nora Shields, Neil O'hare, John Gormley
    Abstract:

    Short-Wave Diathermy (SWD) is a form of electromagnetic radiation used therapeutically by physiotherapists. Its frequency of use has declined for several reasons, including concerns regarding its safety and in particular the possibility of adverse effects on pregnancy. This paper examines the evidence from animal and human studies on the possible hazards of stray radiofrequency (RF) radiation. It was concluded that no association has been found between SWD exposure and spontaneous abortion, prematurity, stillbirth or reduced fertility. An association was demonstrated, however, between SWD exposure and congenital malformations and low birth weight. Research has been completed investigating stray radiation levels in physiotherapy departments but is conflicting in its advice. International guidelines are available to promote the safe use of this equipment but offer little advice for pregnant operators. Further research is therefore necessary to enable all operators to apply treatment safely for both themselv...

  • Short Wave Diathermy current clinical and safety practices
    Physiotherapy Research International, 2002
    Co-Authors: Nora Shields, John Gormley, Neil Ohare
    Abstract:

    Background and Purpose Short-Wave Diathermy (SWD) is widely available, yet a comprehensive examination of current clinical practice remains absent from the literature. The present paper aims to assess clinical and safety issues in continuous (CSWD) and pulsed (PSWD) Short-Wave Diathermy application and subsequently indicate areas for future research. Method A postal survey was carried out among 116 senior physiotherapists in 41 Irish hospital-based physiotherapy departments. Results The response rate to the study was 75%. Analysis found that PSWD was the preferred mode of treatment with 27% of respondents using it more than once daily. Respondents considered both modes of treatment indicated for a variety of conditions. CSWD was rated as an effective treatment for chronic osteoarthritis, polyarthritis, non-specific arthrosis and haematomas. PSWD was reported an effective modality for acute soft tissue injury, haematomas, acute osteoarthritis, sinusitis and rheumatoid arthritis. Dose selection varied greatly but tended to be based on the type, nature and duration of the condition. Analysis of safety practices uncovered concerning findings. Although a high level of agreement was found on measures for patient safety, 30% of respondents reported that no measures for operator safety were taken and only five respondents stated they remained a specified distance from SWD equipment. Measures to ensure the safety of other personnel in the physiotherapy department were also lacking. Conclusions Given the availability of SWD equipment and its apparent efficacy in certain conditions, future research should aim to establish this by means of controlled clinical trials. The findings on safety practices underline the urgent need for comprehensive guidelines to ensure the safety of operators, patients and the general public during SWD application.

  • Contraindications To Continuous And Pulsed Short-Wave Diathermy
    Physical Therapy Reviews, 2002
    Co-Authors: Nora Shields, John Gormley, Neil O'hare
    Abstract:

    The application of electrophysical agents is one of the core treatment techniques used by physiotherapists. The decision to utilize a particular modality is based on the physical and physiological effects of that modality. In order to apply treatment safely, physiotherapists must also be aware of contraindications towards the use of such equipment. Current electrotherapy texts provide only broad contraindications to Short-Wave Diathermy (SWD) treatment, and information to deal with specific scenarios is often lacking. A list encompassing all cited contraindications has, therefore, been drawn up, and the rationale behind their exclusion from treatment discussed. The information derived from this review is expected to be of value to practising physiotherapists and undergraduate students when selecting appropriate electrotherapeutic intervention.

  • Comparing Hot Pack, Short-Wave Diathermy, Ultrasound, and TENS on Isokinetic Strength, Pain, and Functional Status of Women with Osteoarthritic Knees
    2008
    Co-Authors: Nuri Çetin, Aydan Aytar, Ayce Atalay, Mahmut Nafiz Akman
    Abstract:

    Cetin N, Aytar A, Atalay A, Akman MN: Comparing hot pack, Short-Wave Diathermy, ultrasound, and TENS on isokinetic strength, pain, and functional status of women with osteoarthritic knees: a single-blind, randomized, controlled trial. Am J Phys Med Rehabil 2008;87:443‐451. Objective: To investigate the therapeutic effects of physical agents administered before isokinetic exercise in women with knee osteoarthritis. Design: One hundred patients with bilateral knee osteoarthritis were randomized into five groups of 20 patients each: group 1 received ShortWave Diathermy hot packs and isokinetic exercise; group 2 received transcutaneous electrical nerve stimulation hot packs and isokinetic exercise; group 3 received ultrasound hot packs and isokinetic exercise; group 4 received hot packs and isokinetic exercise; and group 5 served as controls and received only isokinetic exercise. Results: Pain and disability index scores were significantly reduced in each group. Patients in the study groups had significantly greater reductions in their visual analog scale scores and scores on the Lequesne index than did patients in the control group (group 5). They also showed greater increases than did controls in muscular strength at all angular velocities. In most parameters, improvements were greatest in groups 1 and 2 compared with groups 3 and 4. Conclusions: Using physical agents before isokinetic exercises in women with knee osteoarthritis leads to augmented exercise performance, reduced pain, and improved function. Hot pack with a transcutaneous electrical nerve stimulator or Short-Wave Diathermy has the best outcome.

  • Heat distribution in the lower leg from pulsed Short-Wave Diathermy and ultrasound treatments.
    Journal of athletic training, 2000
    Co-Authors: David O. Draper, Kenneth L. Knight
    Abstract:

    OBJECTIVE To compare tissue temperature rise and decay after 20-minute Diathermy and ultrasound treatments. DESIGN AND SETTING We inserted 3 26-gauge thermistor microprobes into the medial aspect of the anesthetized triceps surae muscle at a depth of 3 cm and spaced 5 cm apart. Eight subjects received the Diathermy treatment first, followed by the ultrasound treatment. This sequence was reversed for the remaining 8 subjects. The Diathermy was applied at a frequency of 27.12 MHz at the following settings: 800 bursts per second, 400-microsecond burst duration, 850-microsecond interburst interval, peak root mean square amplitude of 150 W per burst, and an average root mean square output of 48 W per burst. The ultrasound was delivered at a frequency of 1 MHz and an intensity of 1.5 W/cm(2) in the continuous mode for 20 minutes over an area of 40 times the effective radiating area. The study was performed in a ventilated research laboratory. SUBJECTS Sixteen (11 men, 5 women) healthy subjects (mean age = 23.56 +/- 4.73 years) volunteered to participate in this study. MEASUREMENTS We recorded baseline, final, and decay temperatures for each of the 3 sites. RESULTS The average temperature increases over baseline temperature after pulsed Short-Wave Diathermy were 3.02 degrees C +/- 1.02 degrees C in site 1, 4.58 degrees C +/- 0.87 degrees C in site 2, and 3.28 degrees C +/- 1.64 degrees C in site 3. The average temperature increases over baseline temperature after ultrasound were only 0.17 degrees C +/- 0.40 degrees C, 0.09 degrees C +/- 0.56 degrees C, and -0.43 degrees C +/- 0.41 degrees C in sites 1, 2, and 3, respectively. The temperature dropped only 1 degrees C in 7.65 +/- 4.96 minutes after pulsed Short-Wave Diathermy. CONCLUSIONS We conclude that pulsed Short-Wave Diathermy was more effective than 1-MHz ultrasound in heating a large muscle mass and resulted in the muscles' retaining heat longer.
