High and low frequency electrode placement, Pt 2

More on electrode high and low frequency electrode pad placement, continuing where Part One left off. 
In fracture pain, for instance a rib fracture, there is often no need to establish the area containing nerves in the painful part of the skeleton. The electrodes should be placed around the pain site; high frequency usually brings relief for pain caused by rib fractures or vertebral compression.
In hip pain, one electrode should be placed at or around hip height, and the other in on the mid-outside of the thigh. High frequency is mostly used, and the color of the pin is irrelevant to its placement. 
In knee pain, the electrodes are placed, using high frequency, on either side of the joint space in order to allow the knee to bend.
In muscle pain, which frequently occurs in the neck and scapular (pertaining to the shoulders) areas, where trigger points and extra-sensitive areas may be found. Electrodes are placed over the painful site, if possible on the tender points. For low frequency intrascapular radiation (between the shoulders), it is recommended to use two sets of electrodes.
In afterpains (cramplike pains caused by contraction of the uterus after childbirth), high frequency electrode placement in the pain is advised, either on the back or stomach, or both. 
In pubic symphysis pain (caused by pelvis misalignment and linked to pregnancy and childbirth), electrodes are placed in the painful area, in the first lumbar vertebra in the groin, or over the sacroiliac joint in the back, but not over the symphysis (the joint that bridges the left and right pubic bones). Use high frequency. 
In labor pain, the sacral region is usually affected, but can be relieved with large electrodes like the 4’’ x 6’’ butterfly foam pads. In addition, place two electrodes on the back and a further two over the hips (down towards the groin), in order to preempt pain moving forward or down, as is it wont to do later on in the delivery. Use high frequency, and do not connect electrodes over the uterus.
In menstrual pain, electrode pads are placed in the painful site, either on the back or the stomach, or both, using high frequency. Acute ischemic pain may warrant the use of high intensity stimulation, which consists of high-frequency stimulation with very high amplitude for a short period of 60 seconds. 
In angina pectoris, the electrodes are placed on the painful area regardless of where the red and black pins go, using high frequency. Like in menstrual pain, high intensity stimulation may be used for acute ischemic pain.
