Interferential therapy electrode placement technique in acute low back pain : a preliminary investigation . OBJECTIVE To determine the efficacy of interferential therapy ( IFT ) electrode placement technique compared with a control treatment in subjects with acute low back pain ( LBP ) . DESIGN Single-blind , randomized , controlled trial with a 3-month follow-up . SETTING Outpatient physiotherapy departments in hospital and university settings . PATIENTS A random sample of 60 eligible patients with back pain ( 28 men , 32 women ) were recruited by general practitioners and self-referral for physiotherapy treatment and randomly assigned to 1 of 3 groups . INTERVENTIONS ( 1 ) " IFT painful area " and The Back Book , ( 2 ) " IFT spinal nerve " and The Back Book , and ( 3 ) " Control , " The Back Book only . Standardized IFT stimulation parameters were used : carrier frequency 3.85 kHz ; 140 Hz constant ; pulse duration 130 micros ; 30 minutes ' duration . MAIN OUTCOME MEASURES Pain Rating Index , Roland-Morris Disability Questionnaire ( RMDQ ) , and EuroQol were completed by subjects pretreatment , at discharge , and 3-month follow-up . RESULTS All groups had significant improvements in all outcomes at follow-up . Subjects managed by IFT spinal nerve and The Back Book displayed both a statistically significant ( p = .030 ) and clinically meaningful reduction in functional disability ( RMDQ ) , compared with management via IFT painful area and The Back Book combined or The Back Book alone . CONCLUSIONS The findings showed that IFT electrode placement technique affects LBP-specific functional disability , providing preliminary implications for future clinical studies .
