Clinical Trial Summary

Chronic low back pain is a common problem which results in reduced functionality, quality of life and general well being. Conservative treatment includes patient education, exercise, maintaining a healthy body mass index and appropriate modifications to activities of daily living. Physical modalities are used to support the mainstay of treatment and include superficial heat, transcutaneous electrical nerve stimulation (TENS), ultrasound, short wave diathermy , traction, and complimentary therapies. In the clinical practice of the investigators, diathermy, in the form of ultrasound and short wave, is used to heat deeper tissues, increase tissue elasticity and metabolic rate and reduce pain and muscle spasm. The medical literature to date states that further studies are required to compare the efficacy of different diathermy modalities in the treatment of lower back pain. The aim of this study was to compare the efficacy of ultrasound to that of short wave diathermy and a treatment program which does not include diathermy in the treatment of a slipped disc.

Description:

Chronic lumbar pain is a common problem which results in reduced functionality, quality of life and well being. Chronic low back pain also results in many missed days of work and so is an economic burden as well as a social one. Subacute and chronic conservative treatment of low back pain secondary to a herniated disc of the lower back includes education, lifestyle modifications, and maintenance of a normal body mass index. Physical therapy includes range of motion, strengthening and aerobic exercises alongside use of physical therapy modalities such as superficial heating, low frequency analgesic modalities such as TENS and deep heating modalities such as ultrasonic waves and short wave diathermy. In Physical Medicine and Rehabilitation departments in Turkey, diathermy is commonly used as an adjunct to exercise in the inpatient treatment of disc herniation of the lumbar region. However, systematic reviews of the effects of diathermy in the form of ultrasound and short wave emphasise the necessity for further studies of their efficacy in the treatment of pain and impact on functionality and quality of life. Therefore, in this study the investigators aim to compare the efficacy of ultrasound and short wave diathermy in treating pain, improving disability and quality of life in patients with chronic low back pain secondary to disc herniation of the lumbar vertebrae.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in level of pain	visual analogue scale (VAS) score from 0 to 10cm for current pain. 0= no pain 10= the worst pain imaginable	Before treatment, 2 weeks after the commencement of treatment, 6 weeks after the commencement of treatment, 14 weeks after the commencement of treatment
Secondary	Change in level of Disability	Modified Oswestry Low Back Pain Disability Questionnaire. The Revised Oswestry Disability Index is a condition specific outcome measure for low back pain. The index consists of ten questions with six possible responses regarding the patient's back pain, (scored from 0-5), including the severity of pain and impact on activities of daily living. The minimum obtainable score is 0, the maximum obtainable score is 50. This score is then used to calculate the index percentage using the formula: [total score/(no. of questions answered x 5)]100. The higher the percentage, the greater the level of disability due to low back pain. The minimal detectable change (90% confidence interval)is 10%, change of less than 10% maybe attributed to measurement error.	Before treatment, 2 weeks after the commencement of treatment, 6 weeks after the commencement of treatment, 14 weeks after the commencement of treatment
Secondary	Change in health related quality of life	Short Form 36 (SF-36).The SF 36 is a generic health survey which assesses health concepts that are pertinent to functional status and well-being such as physical function, bodily pain, role limitations due to emotional and physical problems. The sub scale values are reported: physical functioning, bodily pain, vitality, general health, social functioning, emotional role, physical role, mental health. The lowest and highest possible raw score for the subscales are as follows: physical functioning 10-30, physical role 4- 8, bodily pain 2-12, general health 5-25, vitality 4-24, social functioning 2-10, emotional role 3-6, mental health 5-30. Higher values signify better well being in all subgroups. The raw score is then used to calculate the 'transformed scale: Transformed scale= [(actual raw score- lowest possible raw score)/possible raw score range]100	Before treatment, 6 weeks after the commencement of treatment, 14 weeks after the commencement of treatment
