To Produce Low Frequency Effects At Sufficient Intensity And At Sufficient Depth, Patients Can Experience Considerable Discomfort In The Superficial Tissues (i.E. The Skin). This Is Due To The Impedance Of The Skin Being Inversely Proportional To The Frequency Of The Stimulation. [The Barrier Presented By The Skin To The Passage Of An Electric Current Is More Complex Than Just Impedance, Or Resistance, But Will Be Regarded As Such For The Purpose Of This Explanation] In Other Words, The Lower The Stimulation Frequency, The Greater The Impedance To The Passage Of The Current & So, More Discomfort Is Experienced As The Current Is Pushed Into The Tissues Against This Barrier. The Skin Impedance At 50Hz Is Approximately 3200 Whilst At 4000Hz It Is Reduced To Approximately 40. The Result Of Applying A Higher Frequency Is That It Will Pass More Easily Through The Skin, Requiring Less Electrical Energy Input To Reach The Deeper Tissues & Giving Rise To Less Discomfort.Acco Interferential Therapy Unit(Digital, 29Prg.)TECHNICAL SPECIFICATION :-Programmes: 29 With Digital Display" OPERATING FREQUENCY : 230 Volt AC/50 Hz" Out Put Type : 100% Isolated" Medium Frequency : 4 Khz & 2Khz" Out Put : Two Separate Output CH-1 & CH-2" Out Put Current : 0 To 100ma : 0 To 100ma" Out Put Freq. :It Can Be Varied In 0-150 Hz Constant Mode By Using Beat-freq.Up/down Keys" Display :Green Colour Seven Segment Display."
