The aim of this post is to give you some handy tips and advice with using the electrodes for your electrical stimulation device. Our SaeboStim Pro is used in the tutorial videos at the bottom of this page, but the principles apply to any electrical stimulation device.
Do check back on this blog as the video tutorials are added to over time.
Any muscle lying under an electrode will be stimulated. Therefore select the correct size to ensure only the muscles you want to target are stimulated.
Standard sizes are:
1.25 inch/3.2cm round Consider these smaller electrodes for for smaller muscles e.g. around the thumb.
2 inch/5cm round Most commonly used size.
2 by 3.5 inch/5cm by 9cm rectangular Consider these large rectangle electrodes for larger muscles such as hamstrings and quadriceps
Looking after your electrodes
Electrode Placement – Most commonly used
Click on the videos below to watch our Clinical Specialist talk through various set ups.
Wrist and Finger extension – 1 lead with 2 electrodes. Place 1 electrode just up from the wrist on the finger extensor motor point and place the 2nd electrode further up the forearm on the tendinous part.
Grasp – Finger flexion with thumb flexion and adduction – 1 lead with 2 electrodes. Place 1 electrode near the wrist on the underside of the forearm and the 2nd electrode over the fleshy part at the base of the thumb. You may need to trim the edges of the 2nd electrode as shown in the video.
Alternating between Wrist/Finger extension and Wrist/Finger flexion – 2 leads. First lead is the same electrode placement for wrist and finger extension as described previously on this post. The second lead has one electrode placed near near the wrist on the underside of the forearm and the 2nd electrode about midway up the underside of the forearm.
Elbow flexion – 1 lead, 2 electrodes. Both electrodes placed mid upper arm on the biceps muscle. Ensure they have a minimum of 2 fingers space between them.
Shoulder Subluxation – 2 options available. Option 1 is with 1 lead and 2 electrodes – 1 electrode is placed on supraspinatus (the fleshy part just up from the shoulder blade) and 1 electrode on posterior deltoid (the back of the upper arm, just beneath the subluxation gap). Option 2 is with 2 leads. Set up lead 1 as per option 1 above. On lead 2 place 1 electrode on the middle of the upper arm and the 2nd electrode on the front of the upper arm; both positioned just beneath the subluxation gap.
Foot Drop – 1 lead with 2 electrodes. 1 electrode mid way down the shin on the fleshy part, just off the tibia (this is the bone running vertically down the shin). 2nd electrode is placed with its top right corner on the head of the fibula. To find this bone, run your fingers up from your ankle on the outside of your leg until you hit a bony prominence which is the head of the fibula. Our Clinical Specialist talks through how to make small adjustments to ensure the ankle is lifted with some eversion (ankle pointing outwards).
