This study examined the effects of two different frequencies of Transcutaneous Electrical Nerve Stimulation (TENS) on chronically painful and stiff osteoarthritic knees. The effects studied were changes in pain state, changes in stiffness state, changes in circumference, and changes in range of movement. Three groups, each of 20 subjects, were given a single 30 minute application of TENS: the first group received High Rate (Conventional) TENS, the second group received strong Burst Mode (Low Rate) TENS, and the third (control) group received a placebo application using the same active TENS with nonfunctioning leads. Each TENS frequency was applied for the same length of time, at tolerable intensities, to the same four acupuncture points around the knee. Measurements of joint pain and stiffness using Absolute Visual Analogue Scales were made immediately before and after the TENS application. Objective measurements of joint circumference and range of movement were also made immediately before and after the test, using a tape measure and goniometer respectively. The length of time the post-test pain and stiffness relief lasted was determined by the subject reporting when his
ormal\" pain and stiffness returned. These reports were collected 24 hours after the test. The aim of the experiment was to establish the hypothesis that strong Burst Mode TENS would produce significantly greater and longer lasting effects than those produced by High Rate TENS. The results from the study did not entirely support the hypothesis but the significance of the findings suggested that continuing investigation into TENS action is warranted."
