Reflexology chart
Here is a link to some f r e e charts: https://www.doctemplates.net/free-reflexology-foot-charts/
The photo here is fairly simple, but should be enough information for a therapy beginner, or for home use. If you intend to become a practicing reflexologist there is a lot more to learn.
Reflex nerve endings
The body has more than 800 pressure points, but only 15 of them are found on the feet. Almost all parts of your body have a corresponding reflex area on your foot. The left foot normally corresponds to all the organs located on the left side of your body, and vice versa. Not all experts agree on the precise location of reflex areas, but there is a universal agreement on the major points
Reflexology points
Generally, there are four main reflexology points on the soles of every foot.
(1) The neck and head area involve all the five toes. In this section, you will find different points corresponding to the eyes, ears, and sinuses, among others.
(2) The chest area is found around the foot’s ball. This part is generally darker in color than the center of the foot. It’s connected to the shoulders, lungs, etc.
(3) The spine, which goes up the inside of every foot, is situated where the toes connect to the rest of the foot. This area is the most vital reflexology zone and acts as a highway for all communications between your nerves, your brain, muscles, and bones.
(4) The pelvic area is found at the heel. It’s typically darker in color, just like the chest point of the foot. This part of the feet corresponds to the buttocks and legs. The “waistline” is situated wherever your feet are widest. This part correlates with the liver, intestines, stomach, etc.
You'll want to have a diagram about as big as an 8 x 11 piece of paper. We keep laminated copies in our office.
Nicknames
If you are a therapist, I would recommend having a chart you can view during therapy, and then take notes for follow up sessions. If you are doing reflexology at home, it will help you keep track of what you are doing. If your chart has numbers, you can use that for tracking, or you can note the corresponding organ or body location to which the flex point leads.
Why is this important?
While I don't have clients who use 100% of their therapy session to get reflexology, we occasionally see people who either have a concern that indicates the use of reflexology, OR perhaps they just ask about getting some reflexology.
My experience is that you don't get "really good" at doing something unless you do it often AND with the intent of "getting good". However, a trained therapist should know enough to use a reflexology chart during a session and help their client. If you do start doing reflexology on a client, you'll get better as you learn their situation and get feedback about what works (and doesn't work).
Whenever I do reflexology, I get the client's permission to look at the reflexology chart while I'm working on their feet. We have experienced several noticeable improvements over the years.
